WORKSHOP GUIDE

SAFETY TIPS

. Wear appropriate safety gearwhen operating a woodworkingmachine: safety glasses, a faceshield for extra protection, andhearing protectors or earplugs. lfthere is no dust collection system,wear a dust mask. For exotic woods,such as ebony, use a respirator;the sawdust may cause anallergic reaction.

. Make sure that workshop lightingand ventilation are adequate andthat work surfaces are largeand sturdy.

. Read your owner's manuat care-fully before operating any machine.

. Tie back long hair, roll up longsleeves and avoid looseJitt ingc lo th ing . Remove r i ngs andother jewelry that can catch inmovtng pans.

. Keep children, onlookers andpets away from the work area.

. Unplug a machine beforeperforming setup or installationoperattons.

. Concentrate on the job; do notrush or take shortcuts. Never workwhen you are tired, stressed or havebeen d r i nk ing a l coho l o r us ingmedicat ions that inducedrowsiness.

. Whenever possible, clamp downthe workpiece, leaving both handsfree to perform an operation.

. Find a comfortable stance; avoidover-reaching.

. Turn the machine off if i t producesan unfami l iar v ibrat ion or noise;have the machine serviced beforeresuming operations.

. Keep your work area clean andtidy; clutter can lead to accidents.

INTRODUCTION

Giles Miller-Mead talks about

TABLE SAMS

he first table saw I ever encountered belonged to my friend's dad, a Danish boatbuilder. He'd built it himself out of an assortment of parts of indeterminate age

and origin and it proudly occupied a corner of his worlshop. It always amazed mehow Sven could turn out any number of identical, precisely cut pieces and then, afterchanging his set-up, make lengths ofbeautiful custom moldings. All these operationswere done with seemingly effortless efficiency.

I was always pestering him to let me try using it and, when he finally did, the firstproject we made together was a set of floorboards for my vintage cat a 1938 RoverSports Sedan. Even now, nearly 25 years later, I still look back at Sven and the floor-board project as the first stirrings of my desire to make a living from woodworking.

My present table saw, bought second-hand more than 10 years ago, is a l2-inchcommercial model with a 3-horsepower motor. I couldrlt imagine my woodworkingshop without it. I rely on my table saw at many stages throughout my projects, whethercutting workpieces to size, making different joints, building drawers and doors, orcreating a variety of molding patterns. I also make a lot of chairs in myworlahop andI find my table saw particularly usefirl for cutting the angled tenons on the seat rails.When I built my house, I started by building the worlshop; once that was up, the tablesaw came through for me once again, cutting sheets of plywood to size and makingall the trim for the entire house, as well as cutting other assorted pieces.

I think I like the table saw so much for two main reasons. First of all, it's such a ver-satile machine; second, since most of the motor and blade are beneath the table, youcan see at a glance what's going on. There's nothing to obscure your view of the worksurface. Still, I have a great deal of respect for its ability to cause bodily injury-a lesonthat's been drummed into me on a couple of occasions. But I consider it a safemachine, as long as the proper precautions are observed and the operator isnt overtiredor in too much of a hurry. All in all, the table saw is a magnificent machine and Icouldnt do without it.

A native of New Zealnnd, Giles Miller-Mead is seenhere inhis workshop/with one of his prized tools-avintage table saw acquired in the early 1980s.

Frank Klausz discusses

RADIALARM SAMS

ntil he was about 14 years old, myson was content to spend his sum-

mers in my shop doing sanding jobs.Then he decided to make somethinghimself. I suggested he design a jewelrybox, which I helped him construct. Thenext summer, he wanted to build some-thing without my help-which meantworking on mybig machines.

Being safety-conscious, I got a bit ner-vous. Still, I took him to the radial armsaw and explained the basics. Then Ipainted two red lines on the saw table,each a few inches away from the blade,and filled in the space in between. "Safety

with this machine is simple," I told him."Keep your hands away from the redzone." In no time at all, he was workingat the saw without supervision. He cut/rinch rabbets into the edges of his jew-elry box top and added a black ebonyinlay. I would have used a router, but hedid fine with the saw.

Because you pull the blade into a sta-tionaryworkpiece, the radial arm sawisa very safe machin*provided you set upproperly, use only sharp blades, followthe manufacturer's safety instructionsand, ifyou wish, add your own red zone.

I use the radial arm saw for a varietyof tasks: crosscutting rough lumber,cutting miters and dadoes, and ripping.If you rip, remember to feed evenlyand from the correct side of the table toavoid kickback.

Dave Sawyer talks about

BA)\TDSAMS

J have been a Windsor chairmaker forI l0 years. The machines in my shopare a lathe and a band saw. The lathe isessential; the bandsaw is a wonderfulconvenience. It cuts out seats, trimsrough wood, cuts turnings and spindlesto lengh, saws wedge slots, and is justplain handy. All these jobs could be donewith hand saws, but the band saw doesthem quicker and more accurately.

I was exposed to band saws at an earlyage in my father's display and exhibitshop. later I worked in a boatyard wherethe band saw made many wonderfulshapes. That must have been where Irealized it is my favorite woodworkingmachine. For a small shop limited to onestationary power tool, most folks wouldwant a table saw but a band saw wouldbe my choice.

Obviously, band saws are great forcutting curves, down to tiny radii with%e-inch blades. Angle cuts, straight orcurved, are easy. With a little fore-thought, you can make "release cuts"and get into reallytight places. Band sawsalso do a reasonable job of ripping withalz-inch or %-inch blade and a fence.My l4-inch Delta model will resawboards 6 inches wide-any thicknessfrom veneer on uD. Wth a 6-inch riserblock in its frame ii could resaw 12 inch-es. That would take a monster industrial30-inch table saw to make the samecut-or two passes with a 16-inch saw.

Iudith Ames on

DRILL PRESSES

f all the tools in my shop, the drillpress may not see as many hours

of use as some others, but for certaintasks it is indispensable. The machine Iuse is a Sears Craftsman, manufacturedin the mid-1950s.It came into our shopabout four years ago. What I like aboutthis drill press is its old-tool charm. theweight ofit. It's solid. It was built to last.

Prior to getting into furniture-mak-ing, I experimented with carpentry andcabinetmaking. I studied woodworkingin Colorado, taking classes with suchhighly respected furniture makers as ArtCarpenter. Fumiture-making is what I'vebeen doing for the last seven years. I findit very satisfiing. I'm constantly learningnew techniques and trying new designs.

I produce a line of furniture as well ascustom design pieces. I make a rockingchair for children with a design thatincludes bear paws on the arms anddowels set into a curved frame that pro-vides back support. I depend on the drillpress to bore precise holes for the dowels.

On a rocking chair I make for adults,the legs are square at the middle wherethey meet the seat, and have tenonsat either end that fit into the rockersat the bottom and the arms at the top.To make the transition between the leg'ssquare middle and round tenons,l sculptthe legs with a router and a spokeshave.The drill press reams the holes in therockers and the arms for the tenons.

Mark Duginske talks about

IOINTE,RShe first jointer I used was alreadyold when my father bought it. The

machine required constant care, whichwas good, because it taught me to con-centrate and pay attention to every boardI worked with. When I was 15 years old,we built a new house and used locallygrown oak for the trim and cabinets. Itwas my job to do all of the jointing.

A rule I learned then-and one thatI still follow today-is that the success ofany cabinetmaking project hinges onworkingwith wood thathas straight andsquare edges. The power tools that domost of the cutting in my shop nowa-days-the table saw and the radial armsaw-will cut accurately only if the stockI feed into them is square and true. If oneedge of a board is not straight, I won't beable to crosscut it squarely.

Getting offto a good start is where thejointer comes in. I use it to make thatcritically important first step, forming asquare corner where the edge and theend of a board meet. The jointer also hasa more creative application when I use itto make legs for furniture or even deco-rative moldings.

The jointer is not difficult to use ormaintain, but it requires skill to adjustthe machine and change the knives. Butlike all tools, mastering the jointer takespractice and concentration.

hether you are working withmilled boards from a lumber-

yard, old barn siding or sheets of4-by-8plywood, the table saw is an excellent all-around tool for cutting wood to width(ripping) and length (crosscutting). If thetable saw were used for nothing but tiresetwo cuts, it would still be a valuable tool.But the saw also accepts a wide variety ofblades and accessories, from roller standsthat assist with unwieldy panels (page 26)to molding heads capable of producingelaborate decorative trim (page 40). lndwith help from the simple, inexpensiveshop-made jigs featured in this chapter,the table saw is also unsurpassed forrepeat cuts and also valuable for makingsuch fundamental woodworking jointsas the lap, box and open mortise-and-tenon joints (page 44).

l0-inch blade. Properly tuned and main-tained, it can mill 3-inch stock repeated-ly without overheating.

If most of your work is with 3/E- or l-inch-thick stock typically used for cab-inetmaking, the open-base contractor'ssaw is a less expensive alternative. Its 1.5-horsepower motor turns an 8- or 10-inch blade, and the unit can be mountedon a mobile base, providing extra flex-ibility. In any case, the basic require-ment for a table saw-whether forcabinetmaking or general workshopuse-is that it must be capable of cuttinga2-by-4at both 90 and45".

For occasional use on light stock orwhere space is at a premium, the 8/+-inch bench top saw can easilybe hauledaround the workshop or the iob site byone person. When^ choosing a saw,

The precision and power of a table saw permit a woodworkerto make many different cuts with small risk of error. Sawingsquare and straight with hand tools requires considerable skilland time; but a woodworker who follows the procedures for thetable saw outlined in this chapter can produce clean, accuratecuts-consistently, and with relatively little effort.

Table saws are designated according to the blade diameterused. Models are commonlyavailable in 8-,9-, 10- and l2-indlsizes. The 8- and l0-inch models, however, are clearlythe mostpopular home worlshop saws. When choosing a table saw, firstconsider the type of woodworking you will be doing with it. Thefully enclosed stationary saw, like the one pictured on pagesl4-15, tipically uses a 1.5- to 3-horsepower motor to drive a

beware of exaggerated horsepower ratings. Check the motorplate:An honest l.5-horsepower motor should draw roughly14 amps at 115 volts; a 3-horsepower motor should draw 14 or15 amos at 230 volts.

SETTING UP

hether your table saw sits poisedto make its first cut, or is a sea-

soned machine with a home full of ftrr-niture to its credit, it cannot cut withprecision unless its adjustable parts arein proper alignment. A table saw withmisaligned parts can result in any one ofseveral frustrating problems, includingexcessive vibration, increased risk ofkickback, blade damage, burn marks onworkoieces as well as inaccurate cuts.Even irrors as little as r,/o+ inch can con-promise the quality and strength of apiece of furniture.

The components of your table sawrequiring the most attention are those

that contact and guide the workpieceduring cutting operations: the sarv table,the blade, the miter gauge and the ripfence. Before putting a table saw throughits paces on the cutting techniquesdescribed in this chapter, first set up themachine properly by checking and, ifnecessary, adjusting the alignment of itsparts. For best results, unplug the sawadjust the table insert setscrews to makethe insert oerfectlv flush with the sawtable, and irank the blade to its highestsetting. Then follow the steps shownbelow in the sequence that they appear.There is little point in aligning the mitergauge with the saw blade, for example, if

the blade itself has not been scuared withthe table.

To confirm that your table saw isproperly tuned, make a few test cuts. Agood way to ensure that your saw is cut-ting in precise, straight lines is to cut asquared board in two and flip one of thepieces over. Butt the two cut ends togeth-er. They should fit together without anygaps as perfectly as they did before theboard was flipped.

Because the normalvibration fromcutting can upset proper alignment, tuneyour table saw periodically; many wood-workers take the time to adjust their sawsbefore starting each project.

ALIGNING THE TABLE AND SAW BLADE

' l Checking table a l ignmentJ- Posi t ion the mi ter gauge at the f ront of the saw blade. Hold or c lamp aperfect ly squared wood b lock against the mi ter gauge and but t the end of theblock against a saw blade toolh (above). Then s l ide the mi ter gauge and theblock together toward the back of the table whi le rotat ing the b lade by hand.The b lock should remain but ted against the tooth as the b lade rotates f romfront to back. l f a gap opens between the b lock and the tooth, or the b lockb inds aga ins t t he b lade as i t i s r o ta ted , a l i gn t he tab le f o l l ow ing the owner ' smanua l i ns t ruc t i ons .

SAFETY

Q afety is as much a matter of attituder.J and common sense as correct tech-nique. The table saw is a powerfulmachine; all the safety devices in theworld will not make up for a cavalier atti-tude or rloppy work practices. On theother hand, a woodworker should notapproach a table saw with trepidation; atimid operator, someone reluctant tohold a workpiece firmly whiie cutting it,

faces as many risks as a careless worker.Caution mixed with confidence stem-ming from an understanding of themachine and the task at hand should bethe woodworker's guide.

Read the owner's manual suppliedwith your saw. Before starting a job,make sure you know how to use the safe-ty accessories that are designed to protectyou from specific injuries while operat-

ing the machine. Use devices like pushsticks and featherboards, as shownthroughout this chapter, to protect yourfingers from the blade. A hold-downdevice, such as the one illustrated onpage25,is also a worthwhile investment.And remember that not only your fin-gers and hands are at risk A safe work-shop also includes hearing protectors,safety glasses and dust masks.

Respecting the danger zoneTo avoid injury from the saw blade,constantly be alert to a "danger zone"that exists within obout 3 inches of theblade-both above and to either sideof it (left). Keep your hands out ofthis zone whenever the saw is beingused-even if the blade guard is inplace. To feed a workpiece past theblade within the zone, use a pushstick, a push block or a jig.

. Use a safety guard whenever possible.Before making a bevel cut, confirm thatthe guard wil l be clear of the blade.

o Do not leave the saw running when rtis unattended.

. lf you are interrupted, complete theoperation under way before turning offthe saw and looking up.

. Follow the manufacturer's instructionsto change accessories; unplug the sawfirst. Make sure that saw blades and cut-ters are sharp, clean and undamaged.

. Before cutting a workpiece, removeany loose knots from it using a hammer.Inspect salvaged wood for nails andscrews before cutting.

TABTE SAW SAFETY TIPS

o Do not start a cut unti l the blade isrunning at fu l l speed.

. Before using the saw each time,inspect its safety features. Make surethere is no binding or misalignment ofmoving parts. Do not use the saw untilsuch problems are corrected.

. Always feed wood into the saw bladeagainst the direction of blade rotation.

. Make sure the rip fence is lockedin position before ripping.

. Do not use the miter gauge in combi-nation with the rio fence to make acut-except when the blade does not cutcompletely through the workpiece, suchas for a dado or a groove.

. Use the rip fence or the miter gaugefor all cutting operations; never attemptto cut freehand.

. Before ripping a board, ensure that theedge in contact with the rip fence is smoothand completely straight and that the sur-face against the table is flat.

r Stand to one side of any workpieceduring any cutting operation in case ofk ickback.

. lf you have to reach past the blade,keep your hands at least 3 inches awayfrom it.

. Use a wooden stick, rather than yourfingers, to clear wood scraps from thesaw table.

TABLE SAW

HOW THE BLADE GUARD ASSEMBLY WORKSProtecting fingers and preventing kickbackThe standard table saw blade guard assemblyincludes a pivot ing, c lear-plast ic blade guard,which def lects f ly ing wood chips and reducesthe chance that f ingers wi l l s l ip accidental ly intothe blade. The guard is connected to a thin pieceof meta l known as the sp l i t te r o r r i v ing kn i fe .Attached direct ly in l ine with the blade, the spl i t -ter keeps the saw cut-or kerf-open. Withoutsuch a device, the kerf may close during a cut,binding the blade and throwing the workpieceback toward the operator with great force.Kickback can also result i f a workpiece jamsbetween the blade and the r ip fence. Furtherprotection from kickback is provided by a metalf inger (or f ingers) cal led an ant i-k ickback pawl,which normal ly r ides on the surface of the work-piece. In the event of k ickback, the f inger digsin, prevent ing the workpiece from f ly ing back.

Optional guards like the one shown at left provide extra

flexibility. HeId in place by a cantileuered ann bolted tothe side of the saw table, it features a plasfic shield raisedand lowered by a crank. Resting lightly on the workpiece.the shield serves as a hold-down and provides wide cover-age of the cutting area, allowing the woodworker to per-

For nlost cuts,both arms ride on top of the workpiece, but when the bladeis close to the rip fence one of the arms can be raised out ofthe way. The guard can also be trsed without the retrnct-able splitter when cutting dadoes and grooves-irnpossiblewith the standard guard because the splitter is an integralpart of the framework that holds it in place.

ANATOMY ()F A BLADE T()()TH

I table saw is ortly as good as the saw,f"L blade i t tunrs. A dul l or chippedblade can transform even the best oftable saws into a poor or even dangeroustool. To protect blades from damage,ar,oid stacking them directly atop eachother. Hang them individually on hooksor nlace cardboard between them.Renlace a blade that is dull or cracked orhal chipped teeth; more accidents arecaused by dull blades than sharp ones.

Keeo vour saw blades clean. Wood resinscun gu- r'rp a blade and hamper its abilityto make a smooth cut. To clean stickywoodresin andpitch offablade, soakit inturpen-tine, then scrub itwith steelwool. Spray-onoven cleaner can be used to dissolve stub-born deoosits.

Proolr blade performance is as mucha matter of using the right blade for thejob as keeping it clean and in good con-dition. \\4rereas in the past there wererelatively felv saw blades to choose from,today's woodworker faces a wide array ofoptions. As illustrated below, there areblades designed specifically for crosscut-ting or ripping, others to minimize kick-back or produce thin kerfs, and blades

Brazed to n shoulder on the snw blode,the corlride tip does the utttittg, whilethe gullet retnoves the sawdust. The

for cutting specific types of wood.Regardless of qpe, allblades are installedon the saw and adjusted for cuttingheight and angle in the same rvay(pages 22-23).

The most imoortant advance inrecent years has bein the introduction ofcarbide-tipped blades. These haveeclipsed traditional high-speed steel asthe blade of choice. The advantase ofcarbide-tipped blade, lies in their a6ilityto keep a sharp edge far longer than theirsteel counterparts. Composed of grainsof hard tungsten-carbon particles one-hundredth the thickness of a humanhair, the carbide chunks are bondedwith cobalt and brazed onto the bladewith copper or silver. Carbide is extreme-ly hardl the highest rating-C4-has ahardness value of94 on a scale that ratesdiamond as 100.

\Ahile carbide-tipped blades can staysharp for a hundred hours or more of,se, ihey are more difficult-and there-fore more expensive-to sharpen thanhigh-speed steelblades. Sti1l, most wood-workers believe the price is worth payingfor the advantages they offer.

RIPPING

p ipping has tradi t ional ly beenI\ defined as "cutting with the grain."But considering that some woodstoday-plywood and particleboard, forexample-have no overall grain pattern,the definition needs some amendine. Amore appropriate description focuseJonthe table saw accessory used to make arip cut. Whereas crosscutting is doneusing the miter gauge, ripping involves

the rip fence. (Except for certain cuts thatdo not pass completely through theworkpiece, such as a dado cut, the ripfence and miter gauge should never beused at the same time, or jamming andkickback can occur.)

Before ripping a workpiece, set theheight of the saw blade (page 23), thenlock the rip fence in position for thewidth of cut. The most crucial safety

concern when ripping is keeping yourhands out ofthe bladet path. For protec-tion, use accessories such as push sticks,featherboards and hold-down devices,

To use a hold-down device, it mayfirst be necessary to screw a wood aux-iliary fence to the rip fence. Auxiliaryfences are ideal surfaces for clamping;many woodworkers make them a per-manent fixture on their saws.

RIPPING A BOARD

CROSSCUTTING

s cutting with the grain is synony-mous with the use of the rip fence,

so crosscutting is defined by the deviceused to make the cut: the miter gauge.The general technique for making acrosscut, as shown below, begins withcorrect hand placement to keep theworkoiece both flush on the table andfirmly against the miter gauge. Theworkpiece is fed into the blade at a steadyrate. As with ripping, make sure thatscrap pieces do not pile up on the table,and keep both hands out of line with theblade. Also, keep the rip fence well backfrom the blade to prevent any cut-off

SOUARING THE W(lRKPIECE

part of the workpiece from becomingtrapped between the blade and fence andkicking back.

To reduce the amount of sandingyouwill need to do later, remember that theslower the feed, the smoother the cut,especiallywhen the blade breaks throughthe workpiece at the end of the cut.Althougha combination blade can beused for crosscutting, a crosscut bladewill produce a finer cut.

When a longer workpiece is being cut,it is a good idea to attach an extension tothe miter gauge to provide a more securebase. Miter gauges commonly have

two screw holes for just such an addi-tion-normally, a piece of hardwood3 to 4 inches wide and about 2 feet long.Use the miter gauge extension in con-junction with a stop block to makerepeat cuts (page 32).

For wide panels or long boards, ashop-made crosscutting jig (page 33) isparticularly helpful, and will ensure veryaccurate cuts. Thejig can also be used forsmaller pieces and provides a safe, con-venient way to perform most crosscuts.Many experienced woodworkers consid-er it the single most indispensable acces-sory for crosscutting.

Checking for squareUse a combinat ion square to con-

f i rm that the cut end of the workoieceforms a 90" angle with the edge. Withthe workpiece and square held up to thel igh t , there shou ld be no gap v is ib le .Mark an X on the cut end to help youremember which end has been squared.1 Making a crosscut

CROSSCUTTING A WIDE PANEL

1 Reversing the miter gaugeI to start the cutlf a workoiece is wider than the distancebetween the front edge of the table andthe saw blade, the miter gauge cannotbe used to begin a crosscut in its usualposit ion- in front of the blade. Instead,remove the gauge and insert i t in themiter slot from the back of the table; forextra stability, screw a wooden extensionto the gauge. To begin the cut, hold theextension with one hand whi le pressingthe workpiece against i t wi th the otherhand.

Insert the miter gaugeinto its slot from the front of the tableand complete the cut, holding the work-piece against the extension (rghf).

ANGLE CUTS

A n. of the reasons the table saw is so\-/ versatile is that both the mitergauge and the blade can be angled, pro-ducing not only straight cuts but miter,bevel and compound cuts as well. Mitersof between 30%nd 90o are cut by anglingthe miter gauge. Saw blades can be tiltedfrom 45o to 90' (page 2j),producingbevel cuts. Andbyanglingboth the mitergauge and the saw blade, a woodworkercan make a compound cut.

Whether crosscutting or ripping, thetechniques used for angle cuts are similarto those used when the blade and gaugeare at 90o. The difference is the result:With the blade at 90o, the woodworkerends up with a straight cut; with the

blade angled, a bevel cut. The sameapplies to crosscutting, although withboth activities extra care must be takento keep hands away from the blade,which now cuts a wider swath above thetable. When the blade is tilted, positionthe miter gauge or rip flence soihat the

blade angles away from it. This way theworkpiece is pushed away from the bladerather than pulled toward it, reducingthe chance that hands will stray into theblade. Gluing sandpaper to a miter gaugeextension will also reduce the chance ofa workpiece slipping during a cut.

\Compound cut

TW() JIGS FOR MAKING MULTIPLE ANGLED CUTS

A simple setup for fast repeat cutsScrew a wooden extension to the miter gauge, then use a slid-ing bevel to set the desired cutting angle of the gauge (above).l f you are making a compound cut, use the sl id ing bevel to setthe blade angle (page 23). Push the miter gauge to cut off theend of the extension. Place the workpiece against the exten-sion and l ine up the cutt ing mark with the blade. Clamp a stopto the extension at the opposite end of the workpiece. To makeeach cut, hold the workpiece f i rmly against the extension and,keeping both hands out of l ine with the saw blade, push theworkpiece steadi ly into the blade.

Cutting miter jointsBuild a crosscut jig (page 33) without an extension or a safetyblock. Then, cut two 12-inch-long 1-by-4s and place them at90" to each other in the middle of the j ig, centered on i ts kerf .Turn the j ig over and screw the 1-by-4s to the j ig. To make aseries of cuts, butt the workpiece against the lef t arm of thej ig, al ign the cutt ing l ine on the workpiece with the saw bladeand clamp a stop block to the arm at the end of the work-piece.

DADO CUTS

Q everal woodworking joints call forrJ channels to be cut into workpieces,allowing boards and panels to fittogether tightly and solidly, but incon-spicuously. Four of the most commontypes of channels are shown below(top).They are distinguished from eachother by their relationship to the woodgrain and their location on a workpiece.

Each of these cuts can be made on atable sawwith a standard blade by mak-ing repeated passes along the workpieceuntil the entire width of the channel iscut out. However, a table saw equippedwith a dado head can cut a dado, grooveor rabbet much more efficiently. Thereare several types ofdado heads. The twomost common are the adjustable wobble

dado and the stacking dado shownbelow (bottom).

The wobble dado is a single blademounted on a hub that can be adjustedto provide varying widths of cut.Installed on the saw arbor much like astandard blade, the wobble dado literallywobbles as it spins. The greater thetilt-set by a dial on the blade-thewider the channel cut by the blade .

The stacking dado comprises a pair ofoutside blades that sandwich up to fiveinside chippers. The width of cutdepends on how many chippers aremounted on the saw arbor alongwith the blades. Installing only theblades oroduces a W-inch cut. In-side chippers increase cutting widthinVta- , r /s - o r rA- inch inc rementsup to'%o inch-and up to I inch formodels that include metal shims. Paoerwashers can be added to orovide evenfiner width adjustment. Foi wider chan-nels, adjust the dado head for the widestpossible cut and make several passes.

Although adjustable wobble bladesgenerally are less expensive and simplerto install than stacking models, moststacking dadoes provide better results:channels with more precise widths, flat-ter bottoms and cleaner edges with aminimum of tearout.

From cuning grooves for shelves in abookcase to making a rabbet to jointuvo panels together, dado heads are

an indispensable and versatileaccessory for the table saw.

MOLDINGS

i\ table saw is more than just a machineA to cut wood. With the proper setup,a saw blade can serve as a milling deviceto cut cove moldings (page a3). And byreplacing the saw blade with a moldinghead and different sets ofcutters, a plainboard can become an elaborate molding.Pieces ofwood can be shaped separatelyand then glued together to form animpressive array of designs. The resultsrange from crown moldings for a cabinetto decorative door and frame mold-ings-made at a fraction of the cost oftheir store-bought counterparts.

Molding cutters are sold in sets ofthree, which are installed in a moldinghead and then fastened onto the arbor.By passing the wood over the cuttersrepeatedly and raising the molding headslightly each time, a pattern is cut intothe wood. The more passes, the deeperthe inscriotion.

Like a dado head, a molding headrequires its own table insert with a wideopening to accommodate the width ofthe cutters. A woodworker can make aninsert for each set ofcutters by placing ablank oiece of wood in the table insert

slot and slowly cranking up the moldinghead-much like making special insertsfor saw blades (page 22).

Molding heads have a reputation forbeing dangerous and while there arealways hazards involved when using atable saw there is little risk when mold-ing heads are used with proper care. Afew points to keep in mind: Do not cutmoldings on short lengths of wood; apiece should be at least 12 inches long.Also, do not cut moldings on narrowstrips; cut the moldings on pieces at least4 inches wide and then rio to width.

Millingbaseboard withmolding cuttersThree sets of cutters were used incombination to transform a pieceof walnut into an elaborate base-board molding at little cost (left).More than 30 blade profiles areavailable; by using dffirent cut-ters-also known as knives-onthe same board, an innovativewoodworker can miII an almostlimitless range of designs.

-|1 h. speed and precision ofa table sawI make it an obvious choice for cut-

ting joints, particularly repeat cuts. Oncea saw is adjusted to cut one box joint oropen mortise-and-tenon joint, for exam-ple, five or ten more can be cut in shortorder. The most time-consuming part isthe setup; and much depends upon thecare taken at this point. A few extra min-utes spent at the beginning will result ina strong, Iong-lasting joint. As always,measure twicd and cut once.

Every joint has its own specific qual-ities and applications. Lap joints are fre-quently used to make picture frames.

TABLE SAW OINERY

Made from two pieces ofwood that havehalf their thickness cut away, a lap jointis simple to make. When glued andclamped, it creates a strong joint thatdoes not require reinforcement.

A box joint, also known as a fingerjoint, is ideal for carcase work-for mak-ing drawers or boxes. It consists of inter-locking pins and notches, which are

The mortise-and-tenon joint is oftenfound in chairs and desks. Sometimescalled a bridle joint, it consists of a pro-jection---or tenon-from one board thatslides into a slot-or open mortise-inanother board. Like the box joint, itrequires a jig, which can be shop-built.The following section describes how tomake each of these useful joints.

work table. For most operations, theblade cuts through the workpiece andruns along a kerfin a piece ofhardboardor plywood ttrat is glued to the saw table.

The machine's many pivoting andsliding pars enable it to carry the blade

into a workpiece from a variety of dif-ferent angles and directions. Sliding theyoke along the arm pulls the blade acrossthe table for a crosscut.

SETTING UP

tl- h. setup procedures described onI these pages may seem long and

involved, but do not neglect them.Without careful maintenance, yourmachine will not cut with orecision.A problem with many radialarm sawsis that adjustments are left too loose,allowing excessive play in moving partsand resulting in sloppy cuts. Ideally,clamps should lock tight and slidingmechanisms should be neither too loosenor too snug.

Adjust the table (right), the clamps(below) and the sliding mechanisms(page 54)before every new project. Eachtime you use the saq clear the sawdustflom the gap between the table and thefence, and clear the track underneath thearm. Periodically, touch up the movingparts with a silicone-based lubricant. It isalso important to square theblade (page55) and check for heeling (page 56).

Before using your saw for the firsttime, you will need to install a fenceand an auxiliary table (page5Z). To testyour adjustments, crosscut a l2-inch-wide board and a 1-by-3 standing onedge, then check the cut ends with acarpenter's square.

RADIAL ARM SAW BLADES AND ACCE,SSORIES

:' ike its shop cousilr the table saq thel,-... radial arm saw is only as good as theblade on its arbor. To get the best perfor-mauce from your machine, keep itsblades clean and in good repair. Inspectthe arbor washers and blade collars, andreplace any damaged parts. Use a rag torvipe sirwdust or loose dirt from a blade;remove resin or pitch lvith steelr'voolandturpentine. Spray-on oren cleaner is alsouseful for dissolving stubborn deposits.To protect blades from damage, hangthern individually on hooks or, if youstack then, place cardboard betweenthem. Replace blades rvhenever theybecone crtrcked or chipped; sharpennon-carbide tipped blades regularly. Adull or damaged blade is rnore likely tocontr ibr"r te to accidents than a sharpbl i rde in good corrdi t ion.

In general, the radial arm saw uses thesanre types ofblades as a table saw (pnge20). Combination blades are suitable for90 percent of the jobs ,vou will be doing.Blades for specific jobs, such as cross-cutting or ripping, are also available. In

any case, it is important to consider thehook angle of a blade (left). The largerthe angle, the bigger the bite-and thegreater the r isk oia blade nrnnirrg acrossa workpiece when crosscutting or liftingstock when ripping. In both cases, feedthe blade through the rvorkpiece slowlyand firmly. While a hook angle of 30owould be suitable for a table saw, thesame blade on the radial arm saw couldprove unsafe. The ideal hook angle for aradial arm saw is I 5o or less.

Carbide-tipped blades are the choiceof most woodworkers today. Althoughthey cost more than the traditional high-speed steel blades and are more expen-sive to have sharpened, they hold theiredge considerably longer and are capableof more precise cuts.

In addition to sarv blades, the radialarm saw also accepts vanorls accessories,which are attached to either the arbor oran accessory shaft at the opposite end ofthe motor. On some models, the shaftcan spin at more than 20,000 rprn, mak-irrg i t ideal for porvering roLrter bi ts.

CHANGING A SAW BLADERemoving and installing bladesUnp lug the saw, lock the c lamps andremove the blade guard. Then, fit one ofthe wrenches suppl ied with the sawon the arbor between the blade and themotor. Holding the arbor steady with thistool, use the other wrench to loosen thearbor nut. (Radial arm saw arbors usuallyhave reverse threads; the nut is loosenedin a clockwise direction.) Remove the nutand the outer blade col lar, then sl ide theblade from the arbor. To instal l a blade,place it on the arbor with its teeth point-ing in the direct ion of blade rotat ion.Install the collar and start the nut by hand.With one wrench on the arbor proppedagainst the table, f in ish t ightening thenut ( lef t) , but avoid overt ightening.Ins ta l l the b lade guard .

SETTING THE BLADE HEIGHT

Preparing to make a cutFor a standard vert ical cut, lower the bladeinto one of the precut kerfs in the auxiliary table(page 57). For a cut partway through a work-piece, such as a dado cut, mark a l ine on theworkpiece for the depth of cut, then set thestock on the auxi l iary table and lower theblade to the line. For most saws, one turn ofthe elevating crank raises or lowers the bladetb or rAo inch. To gauge the crank on your saw,lower the blade to within % inch of the auxi l -iary table, then crank in the opposite direc-t ion unt i l the blade begins to move up. Holda piece of scrap wood that is at least I inchthick against the fence and cut into i t at oneend. Turn off the saw and raise the blade byexact ly one turn of the elevat ing crank. Sl idethe workpiece about % inch to one side andmake another cuI (right). The difference indepth between the two cuts wi l l show theamount the blade raises or lowers with oneturn of the crank.

SAFETY

I lthough the many moving parts ofA a radial arm saw make it one of themost flexible machines in the worlshop,they also make it one of the most dan-gerous. Crosscutting-the most basic useof the saw-requires you to pull theblade toward your body. And dependingon the setting of the arm, yoke andmotor, the blade can make its approachfrom several directions and angles. Wthevery cut, you have to anticipate exactlywhere the blade will end up.

When you rip boards on a radial armsaw, you feed the workpiece into the

RIPPING SAFELY

blade, and this demands even greatercare and concentration. The chances ofkickback are high enough that the safetydevices illustrated below and at rieht areabsolutely essential.

Armed with a thorough knowledge ofthe machine's operation, you can ap-proach it with a healthy mixture of cau-tion and confidence-as you would withany other power tool in your workshop.Make certain that all the clamps forholding the arm, yoke, carriage andmotor in position are locked wheneveryou turn on the saw Also be sure to

familiarize yourself with the owner'smanual for your machine, and take thetime to set up the many safety accessoriesand blade guards that are available.Remember, however, that no accessoryorguard can compensate for a lack of care-ful attention and common sense.

For any cut, keep your fingers at least6 inches away from the blade; use pushsticla or featherboards where possible tofeed or hold the workpiece. Wear safetyglasses at all times, and a mask or respi-rator and hearing protection for extendeduse of the saw.

Sefting up for the cutUnplug the saw, then set the workpiece on the table so that you wi l l befeeding against the drrection of the blade's rotation. (Most blade guardshave an arrow indicat ing which way the blade spins.) Fol low the owner'smanua l ins t ruc t ions fo r se t t ing the he igh t o f the an t i -k ickback dev iceand for positroning the nose of the blade guard so that it just clears theworkpiece. For added protection against kickback, install a wheeled hold-down device (pages 61 and 60 or spring-type hold-down fingers (page61). Feed the workpiece steadily (above), making sure that neither handis in l ine w i th the b lade.

RADIAT ARM SAW SAFETY TIPS

. Never insta l l b lades or otherdevices on both the arbor and theaccessory shaft at the same time.Keep a safety screw cap or guardover the accessory shaft when it rsnot in use to prevent it from snag-ging hai r or c loth ing.

o Never ooerate the saw without ablade guard. Use specialty guardsfor crosscuts and for molding or dadocuts with the motor and blade in thehorizontal position. When making arip cut, adjust the height of the anti-kickback device for the workpiece,

o Before starting a cut make sure thatthe motor is at full operating speed.

o Do not r ip a workpiece that isshorter than 12 inches. When makinga crosscut on stock shorter than7 inches, use a hold-down device,rather than a hand, to secure theworkpiece to the table or the fence.

r When ripping, ensure that the edgeof the workoiece in contact with thefence is smooth and straight; feedfrom the side of the table oppositethe splitter and anti-kickback device.

. To avoid kickback, always hold theworkpiece securely against the tableand fence when crosscutting.

o After making a crosscut, lock the ripclamo as soon as the blade is backbehind the fence.

ANTI-KICKBACK DEVICES AND SPEGIALTY GUARD

Another safety accessory for use in ripping andmolding operations is the set of metal hold-down fingers shown at right. Clamped to

L-shaped rods that extend over the fence oneither side of the blade, the fingers push the

workpiece down on the table. The rods canbe adjusted to accommodate various sizes

of stock.With the motor tilted to its horizontalposition, a special guard covers the portion

of the blade facing the front of the table. Touse the guard, you must frrst make a cutoutin the fence to allow the device's shield to belowered onto the workpiece. Before turning

on the saw, spin the blade by hand to ensurethat the guard does not obstruct it.

The hold-down device shown at left fen-tures rubber wheels that ride alongthetop of the workpiece, pressing it downagainst the table. The mechanism isinstalled at a slight angle so that thewheels also push the workpiece againstthe fence. The wheels and collar canbe adjusted to accommodate work-pieca ofvirntalf any thickness. To helpprevent kickback, the wheels aredesigned to rotate in one direnion only.Whm the yoke is rotated to the out-ripposition (page 67) and the workpieceis fed from the other side of the table, thewheek are swung around to turn in theopposite direction.

Page 64: Vol.20 - Woodworking Machines

CROSSCUTTING

-[t h. radial arm saw is best known forI its convenience in crosscutting. The

technique is straightforward: Hold theworkpiece firmly against the fence andpull the yoke and the blade through thestock. Since the thrust of the blade isdownward and toward the back of thetable, the cutting action helps to keep theworkpiece pressed against the table andthe fence. However, several factors cancause the blade to climb uo on the work-piece and jump toward you. Theseinclude a dull blade or one with teeth toolarge for the job at hand, poor qualitywood, or loose roller bearings. But evenwith equipment in proper repair, it is stillessential to remain in control of the bladeat all times.

As a rule of thumb, hold the work-piece against the fence with your lefthand, keeping it at least 6 inches fromthe blade; use a clamp to secure shortstock (page 64). Wth your right hand,pull the yoke, gripping it firmly to con-trol the rate of cut. The slower the feed,the smoother will be the results. To cutseveral workpieces to the same length orto saw a thick workpiece in more thanone pass, clamp a stop block to the fence,as shown below.

MAKING REPEAT CUTS

MAKING A CROSSCUT

Grosscutting a boardButt the workpiece against the fence with the 90" kerf in the fence lined upwith the waste side of the cutting mark. Support long stock with roller standsor a table. Holding the workpiece snugly against the fence, turn on the saw,release the rip clamp and pull the yoke steadily through the cut (above)wiIh-out forcing the blade. Once the blade cuts through the workpiece, push theyoke back, returning it to its place behind the fence. Lock the rip clamp.

Using a stop blockCut a small notch from one corner of the stop block, asshown, to prevent sawdust from accumulating betweenit and the workpiece. Measure along the fence to theleft of the kerf the length of the piece you need to cut;clamp the block at that point. Butt the workpiece againstthe block and the fence, then make the cut (/eff). To cuta thick workpiece in two passes, clamp the stop block tothe fence and cut hal fway through the stock, then f l ipthe workoiece over and f inish the cut.

62

Page 65: Vol.20 - Woodworking Machines

ANGLE CUTS

iter, bevel and compound anglecuts can be made with the radial

arm saw by tilting or angling its blade.The machine's arm swivels to the risht orthe left for miter cuts; the motoi tiltsclockwise and counterclockwise for bevelcuts. Comoound cuts involve bothswiveling the arm and tilting the motor.As discussed on page 65, you can alsomake a miter cut with a jig that hoidsthe workpiece at an angle.

Both the arm and the motor have pre-set stops at 45o angles. To eliminate anyplay in these index settings, push the armor motor as far as it will go in the stoppositions and hold it there while you lockthe clamo. To set the arm and motor atother angles, use a sliding bevel or thesaw's miter and bevel scales for precise

MAKING ANGLE CUTS

results. Always make a test cut first in apiece of scrap wood and measure the cutend with a protractor; then make anyfinal adjustments.

Whenever possible, make miter cutswith the arm swiveled to the right, ratherthan to the left. Working on the left sideof the table, you run the risk of pullingthe blade beyond the table's edge. You

often can make the same cut on the rishtside by turning the workprece over.

Regardless of the type of angle cut,you first need to cut a kerfin the fenceand the auxiliary table to provide a pathfor the blade. Make the kerf uo to % inchdeep ior miter cuts, or deep inough iorthe blade teeth to be below the table sur-face for bevel or comoound cuts.

MITER JIGTo make 45" miter cuts withouthaving to swivel the arm on the saw,use the shop-built j ig shown at right.The j ig holds the workpiece at anangle, so that the blade can remainin the 90" crosscutt ing posit ion.Refer to the i l lustrat ion for sug-ges ted d imens ions .

Before building the jig, make 45"miter cuts in the ends of two oiecesof 7a-plywood that will serve asguides. Then cut the base and thefence and screw the two boardstogether, leaving enough of thefence protruding below the base tofit into the slot between the frontaux i l ia ry tab le and the spacer ,Remove the s tandard fence andset the base on the tab le , sand-wiching the j ig 's fence between

the front surface and table sDacer.With the blade in the 90" crosscut-t ing posit ion, s l ice through the j igfence and % inch deep into the base,pulling the yoke forward as far asit will go, Turn off the saw.

Screw one of the guides to thebase so that i ts mitered end is

f lush against the fence with i tspoint touching the kerf in thebase. Position the mitered end ofthe second guide f lush with thefront of the table as shown. Use acarpenter's square to set the sec-ond gu ide a t a 90" ang le to thef i rst one.

RIPPING

hether you are cutting with thegrain ofa piece ofhardwood or

softwood, or sawing along the length ofa plywood panel with no defined grainpattern, ripping on a radial arm sawbears little resemblance to crosscutting.Rather than pulling the blade across astationary piece of stock, you will belocking the yoke in a position that holdsthe cutting edge parallel to the fenceand feeding the workpiece into the cut.

Depending on the width of the stockto be cut, the yoke can be rotated in twodirections. For a narrow cut, typicallyup to 14 inches, the yoke is rotated to

position the blade close to the fence.This is called the in-rip position. Forwider stock, the yoke is rotated in theopposite direction, leaving the blade far-ther from the fence in the out-rip posi-tion. For the maximum width of cut,relocate the fence behind the rear tableand use the out-rip configuration.

Because ofthe risk ofkickback andthe fact that you will be feeding theworkpiece with your hands, rippingdemands great care. Tiy to stand to oneside of the stock as you feed it to theblade and keep your hands at least 6inches from the cutting edge. Use a

push stick to feed narrow stock or tocomplete a cut on a wide workpiece.Where possible, use featherboards tohold stock firmly against the fence.

As illustrated below, a good hold-down device will provide an additionalmeasure of safety. Plan your cuts safely(page 60), always feeding the workpieceagainst the direction ofblade rotation:from the right-hand side of the table foran in-rip and from the left-hand sidefor an out-rip. Use the blade guardwhen ripping, and it is a good idea toinstall a new fence to keep the work-piece from catching in old kerfs.

RIPPING A BOARD (IN.RIP)

1 Installing a hold-down deviceI Unplug the saw, release the yoke clamp and rotate theyoke to the in-rip position; lock the yoke clamp. To positionthe blade for the width of cut you need, release the ripclamp, slide the yoke to the appropriate distance from thefence, and relock the clamp.

To install a wheeled hold-down device, replace the standardfence with an auxiliary fence about 1 inch thick and slightly

higher than the thickness of the workpiece. Use the templatesupplied with the device to bore three sets of holes along the topedge of the fence; one set should be directly in line with theblade and the others to either side of the first. Fit the pins onthe bottom ofthe hold-down device into one set of holes andt ighten the thumbscrew using a wood block to distr ibute thepressure evenly along the fence.

DADO CUTS

t|a h. same range of dado cuts that canI be made on the table saw (page36)-the cross-grain dado, the groove,the stopped groove and the rabbet-arealso possible on a radial arm saw As youwill discover in the pages that follow, theability of the radial arm saw to functionin either vertical or horizontal planesmeans that there is often more than oneway to make the same cut. Generally,most woodworkers find it easiest to keepthe blade in the 90o crosscutting positionwhen making cross-grain dadoes, rabbetsalong the ends ofstock and grooves in

wide boards. Moving the blade to thehorizontal position work best for a rab-bet along the edge ofa workpiece or fora groove in a narrow board.

There is a way of cutting grooveswithout a dado head. With a standardsaw blade you can make cuts on bothedges ofthe groove and then saw out thewaste between them in as many passes asis necessarv. But the iob can be donemore quickly and preiisely with a dadohead mounted on the arbor. The radialarm saw accepts either the adjustablewobble dado head or the stacking dado

(page j6). Although the stacking dadohead is generally more expensive andtakes longer to install, it produces cutswith flatter bottoms and smoother edges.

The wider swath cut bv the dado chip-pers and blades, compared to the relative-ly narrow width of a standard saw blade,means that you will have to feed the stockmore slowly. For safety's sake, keep trackof the dado head during a cut, noting itslocation on the table when the workpiecehides it from view. Install a standardguard or a dado head blade guard whenthe blades are turned horizontally.

Adding blades and chippersRemove the blade from the arbor (page59 and install a dado head followingthe manufacturer's instructions. For thes tack ing dado shown, f i t a b lade onthe arbor with the teeth point ing in thedirect ion of blade rotat ion.

MOLDINGS

f utting moldings is another of the\-r wood-shaping chores that fallswithin the repertoire of the radial armsaw. The same wide range of cuttersavailable for the table saw (page 40) canalso be used on the radial arm saw totransform boards into pieces of trim.Multiple boards can be shaped indiv-idually and then glued together to forman impressive array of designs. Theresults can range from cornice moldingfor a cabinet to decorative door andframe treatments.

CUTTING A MOLDING

Setting up and making the cutFit the cutters into their slots in the mold-ing head, then use a hex wrench totighten the setscrews (inset). lnstall themolding head on the saw with the f latside of the cutters facing the direction ofblade roiat ion. Mark a l ine for the widthof cut on the leading end of the work-piece, then posit ion the stock f lushagainst the fence. To secure the work-piece, clamp one featherboard to thefence to the lef t of the moldtng headand a second featherboard to the table.Brace the second featherboard with asupport board. Holding the workpieceagainst the fence, slide the yoke to alignthe molding head with the cutt ing l ine,setting up for a 7e-inch-deep cut. Removethe workpiece and turn on the saw. Useyour right hand to feed the stock slowlyinto the molding head (right); use yourleft hand to press the workpiece flushagainst the fence. To keep your handsfrom gett ing too close to the cutters,f in ish the pass with a push st ick. Fordeeper cuts, make as many Passes asnecessary, moving the molding head 7einch farther into the workpiece at a time.After successive Dasses have reduced thestock to the desired depth, make a f inal ,very shallow pass, feeding more slowlyto help produce a smooth f in ish.

Start by fitting a set ofthree identicalcutters into a molding head, which isthen attached to the saw's arbor in thesame way as a blade. Although the illus-tration below shows the molding head inthe horizontal position, the radial armsaw can turn this device at any anglebetween 0o and 90o, significantly extend-ing the range of designs you can pro-duce. Regardless of the molding headangle you decide to use, the workpieceshould always be fed repeatedly acrossthe spinning knives, with each shallow

pass cutting a little deeper until thedesired profile is milled.

Wittrthe molding head in the hori-zontal position, install an auxiliary table(page72) to raise the stock to the level ofthe knives. Install a molding head guardto protect your fingers from the cutters,positioning its shield just above theworkpiece. Do not cut moldings fromstock shorter than 12 inches long. Andrather than working with narrow stock,use wider boards and then make a riPcut to trim them to their final width.

or ease of operation and wide-ranging utility the band saw is

hard to beat. It is the only wood-working machine capable of makingboth straight and contour cuts. Inaddition to crosscutting and ripping,it is well suited for cutting curves andcircles, enabling the woodworker toproduce anything from a dovetailjoint to a cabriole leg.

Both rough and detcate work fallwithin its domain. Fitted with a7z-inch blade-the widest size avail-able for most consumer-grademachines-a band saw can resaw6-inch-thick lumber into two thin-ner pieces in a single pass. And with

toward the operator, kickback can-not occur. For this reason, the bandsaw is the tool of choice for rippingshort or narrow stock.

Band saws are classified accord-ingto their throatwidth-that is, thedistance between the blade and thevertical column, which supportsthe machine's upper wheel. Bandsaws for home workshoos fall in the10- to l4-inch range. Siws are alsocategorized according to their depth-of-cut capaciry which correspondsto the maximum gap between thetable and the upper guide assembly(overleaf). Although a 4- to 6-inchdepth of cut is typical for con-

a %o-inch blade, a band saw can zigzagitsway through a boardat virtually any angle, even making 90o turns during a cut.

But do not let this tool's versatility intimidate you;the bandsaw is surprisingly easy to use. Many cuts can be made free-hand by simply pivoting the workpiece around the blade.With the cutting techniques and shop-made jigs presented inthis chapter, you will be able to turn out intricate curves)cut perfect circles and produce uniformly square-edged ripcuts and crosscuts.

One other advantase ofthe band saw over other wood-working machines is itsielative safeness. Compared to the radialarm saw or table saw, the band saw is a quiet machine, so noise-related fatigue is rarely a problem. Moreover, very little of theblade-usuallv onlv 7e inch-is ever exposed while it is run-nirrg. And since the cutting action of the blade bears downon the workpiece, pushing it against the table instead of back

sumer-grade saws, the band saw shown on pages B0-Bl offersa height attachment that extends the vertical column toprovide a l2-inch depth of cut-handy for resawing particularlythick stock. But even with a standard machine, you can takeadvantage ofthe band saw's unsurpassed depth-of-cut capacityby cutting identical patterns into several pieces of woodstacked one on top of another. Imagine that you wanted tomake the same curved cut on 12 pieces of Vz-inch plywood.With a band saw you would simply stack the pieces, raise theguide assembly so that 6 inches of the blade is exposed andcut them in a single pass.

In choosing a band saw, look for one with a sturdy table thatcan tilt 45o in one direction and at least 10" in the other. In addi-tion, consider spending a little more for a 3/+-horsepower motor.For certain jobs, such as resawing a thick piece of stock, you willbe slad to have the extra power.

A %-inch band saw blade weaves its way alonga curved cuttingline, paring away a block ofmahogany to form a graceful cabriole leg.

ANATOMYOFABAND SAW

I s the name suggests, a band sawA blade is a continuous steel band.Varying in length from roughly 72 inchesto 104 inches depending on the size ofthe machine, the blade runs around rub-ber-rimmed wheels and passes throughan opening in the saw table. One of thewheels-typically the lower one-is thedrive wheel, which is turned by a motor.The blade is not fastened to the wheelsbut is held in place bytension and turnsthrough its elliptical path at roughly3,000 feet per minute-the average cut-ting speed for a l4-inch saw.

The blade is kept taut by means ofa tension handle. which raises and lowersthe upper wheel. A tilt knob that cantsthe upper wheel is used to keep the bladecentered on the wheels. The blade is keptsteady on its path by thrust bearingslocated behind the blade above andbelow the table, and by guide blocks,which prevent lateral movement.Although some cuts can be made free-hand, a rip fence and miter gauge areavailable with many models to guideworkpieces across the table.

The three-wheel band saw's wide throatcapacity - typically 20 inches, rather thanthe 10 to 14 inches available on most two-wheel models-makes it more convenient forworking with particularly large workpieces.

SETTING UP

he band saw has a reputationamong some woodworkers as a rel-

atively imprecise cutting tool. And yetband saws are routinely used in industryto cut very hard materials such as metalto very close tolerances. The factremains, however, that the tool can onlybe made to cut straight edges and pre-cise curves if it is kept finely tuned.

The ideal is for the blade to cutsquarely into the workpiece, producinga smooth, accurate result. But the pecu-liarities of band saw geometry can makethis ideal difficult to achieve. After bend-ing around the machine's wheels at 35

ALIGNING THE WHEELS

miles per hour, a section of the blademust straighten out by the time it reach-es the saw table a split second later.

For this to happen, the adjustableparts of the saw must be kept in properalignment so that the blade runssmoothly and square to the table.Particular attention should be paid to thewheels, the guide assembly and the sawtable itself.

To tune your band saw, unplug it,install and tension the blade you plan touse (page 87)then follow the set-up stepsdetailed on the following pages. lake thetime to do it right. Adjusting the band

saw may be more tlme-consummg thanlearning how to operate the tool. But theadvantages of a well-tuned machine willbe noticeable not only in the quality ofthe results but in the longevity of yourblades and of the band saw itself.Misaligned wheels or poorly adjustedguide blocls can lead to premature bladewear or breakage.

Installing nonmetallic guide blocls ona band saw can reduce wear and tearappreciably (page B3), but there is nosubstitute for getting around the need tocheck thrust bearings, guide blocks andwheels for proper alignment.

1 Checking wheel alignmentI To make certain that the wheels are oaral lelto each other and in the same vertical plane, loosenthe table lock knobs and tilt the table out of the way.Open both wheel covers and hold a long straightedgeagainst the wheel r ims as shown. The straightedgeshould rest f lush against the top and bottom ofeach wheel. l f the wheels are out of al ignment, t ryto br ing the top wheel to a vert ical posi t ion bymeans of the t i l t knob. l f the straightedge st i l l wi l lnot rest f lush, you wi l l have to adjust the posit ionof the upper wheel (step 2).

r) Shifting the upper wheel1 Movethe upper wheel in or out on itsax le fo l low ing the ins t ruc t ions in yourowner's manual. On the model shown, youmust first remove the blade (page 87)and the wheel. Then shif t the wheel byeither adding or removing one or morewashers (/efD. Reinstall the wheel andt ighten the axle nut.

ADJUSTING THE GUIDE ASSEMBTIES

1 Sefting the thrust bearingsI Set the upper guide assembly @age 85), then check byeye that the upper thrust bearing is square to the blade. lfnot, loosen ihe guide assembly setscrew, adjust the assemblyso that the bearing is square to the blade, and tighten thesetscrew. Then, loosen the bearing thumbscrew and turn theadjustment knob until the bearing just touches the blade.Back the bearing off slightly (above) and tighten the thumb-screw. (The lower thrust bearing, which is located directlyunder the table insert , is adjusted the same way.)To checkthe setting, spin the upper wheel by hand. lf the blade makeseither bearing spin, back the bearing off slightly and recheck.

r) Setting the guide blocksL fo set the upper guide blocks, loosen the guide blocksetscrews and pinch the blocks together using your thumb andindex finger until they almost touch the blade. Alternatively,use a slip of paperto set the space between the blocks andthe blade. Iighten the setscrews. Next, loosen the thumbscrewand turn the adjustment knob until the front edges of the guideblocks are just behind the blade gullets (abovd. Tighten thethumbscrew. Set the lower guide blocks the same way.

Heat-re sistant guide blo clesDesigned to replace the metal guide blocks suppliedwith most saws, nonmetallicblocks are made froma graphite-impregnated resin that contains a drylubricant. Because they build up less heat than con'ventional guide blocks, the nonmetallic variety lastlonger; they can also be set doser to the blade, pro-moting more accurate and controlled cuts. In addi-tion, contact between the blade and nonmetallicblocks does not dull theblade, as is common withmetalblocks. To install, unscrew the guide blocksetscrews, remove the old bloclcs and replace withthe new blocks; tighten the setscrews.

SAFETY

CUTTING SAFELY WITH THE BAND SAW

f ompared to the table saw or radialU arm saw the band saw seems Iike arelatively safe machine. There is noaggressive whine of a IVz- or 3-horse-power motor turning a lO-inch sawblade; instead, the band saw produces acuiet hum that some woodworkers likentb the sound of a sewing machine. Andwith its blade guard properly set, nomore than % inch of the blade is exposedabove the table.

Still, it is impossible to be too carefulwith anywoodworking machine and theband saw is no exception. Band sawblades occasionally break, and when

they do they tend to fly to the right ofwhere the operator normally stands'Therefore, it is wise to stand slightly tothe throat column side of the bladewhenever possible. If a blade snaps, turnoffthe saw and do not open the wheelcovers to install a new blade until thewheels have stopped completely.

Although the blade guard adequatelycovers the blade above the table, thereis no guard at the level of the tableor underneath it. As a result, you needto keep your hands out ofthe hole cov-ered by the table insert and refrainfrom reaching under the table to clear

debris from the blade before the bladehas come to a stop.

Most of the accidents that occur withthe band saw are a result ofexcessive feedpressure and poor hand position. Feed aworkpiece steadily into the blade, butwith a minimal amount of pressure' oth-erwise the blade may jam and break. Formost cuts, feed the workpiece with onehand, using the other hand to guide it.Keep your fingers out of line with theblade. Hook the fingers of the feed handaround an edge ofthe workpiece to pre-vent them from slipping into the bladeas your hand nears the cutting area.

BAI{D SAW SAFETY TIPS

o Except when changing a blade,always keep the wheel covers closed.

r Make sure that saw blades are sharp,clean and undamaged. Disconnectthe saw before changing a blade,

o Stand slightly to the left of theblade when cutting at the front of theband saw table. Do not stand, or allowanyone else to stand, to the right ofthe blade. This is the direction inwhich the blade wil l f ly if i t breaks.

o Do not cut unti l the blade is turningat full speed.

. Keep your hands away from theblade when the saw is on. Use a Pushstick or a jig to cut small or nanowoieces.

r Avoid making turns that are too tightfor the blade you are using. This canbreak the blade.

. Cut with the blade guard no morethan % inch above the workPiece.

r Before backing out of a cut, turnoff the saw.

Setting the upper guide assembly and blade guardBefore turning on the saw to begin a cut, set the upper guide assembly 7a inchabove the workpiece. Use one hand to hold the guide assembly in posit ion andthe other hand to tighten the guide assembly lock knob bbove). Alternatively,use the workpiece to lever the guide assembly up slightly, then tighten the lockknob. Setting the guide assembly as close to the workpiece as possible not onlyprotectsyou from the blade when the saw is running; i t a lso supportsthe bladeas i t cuts, minimizing excessive blade def lect ion.

BAND SAWBLADES

T umber mill band saws regularly useI-r blades as wide as l2 inches to cutlogs into boards. Blades for consumer-grade saws are much smaller-generallyranging fromrAe toVzinchwide. Buteven within this relatively narrow spec-trum, choosing the best blade for the jobis not always straightforward. There is nosingle all-purpose combination blade inband sawing, nor any blade specificallydesigned for ripping or crosscutting.However, a woodworker should keepthree basic variables in mind: toothdesign, blade width and blade set.

As illustrated at right, band sawbladesfor cutting wood are available in threebasic tooth designs; each design doessomething better than the others. Thechart below shows the importance ofselecting a blade of appropriate width forcutting curves. In general, narrowbladesare used for cuts with intricate curves,while wide blades are ideal for resawinqthick stock.

Blade set refers to how much theblade teeth are angled to the side, makinga saw cut-or kerf-that is wider thanthe blade. This reduces the chance of thebladebinding in a cut. Abladewith min-imal set, called a light set blade, producesa smooth cut and a narrow kerf, but isalso more prone to binding, which limitsits ability to cut a tight curve. A heavy set

blade-one with greater set-cuts fasterthan a light set blade, and is less likely tobind due to its wider kerf. However, aheavy set blade leaves more visible cor-rugated marla in the cut edge of a work-piece, an effect called "washboarding."

There are enough stresses on a bandsaw blade under the best of circum-stances without adding to them byimproper operation of the machine.Some of the many avoidable causes ofblade breakage include forcing a bladearound a curve that is too tight for itswidth, improper adjustment of the bladeguides, excessive feed speed or pressure,dull blade teeth, excessive blade tension,insufficient tooth set and running theblade for extended periods without cut-ting. Tension and track a blade (page 88)immediately after you install it. Incorrecttension can shorten the life ofa blade.

The typical band saw blade has a looplength of several feet. To reduce theamount of storage space, fold the bladeinto three loops as shown on page 87.Clean a band sawblade regularlyto keepit from gumming up with resins andpitch. Use a wire or stiff-bristled brushdipped in solvent such as turpentine,oven cleaner or an ammonia-basedcleaner. Before storing a blade or forremoving rust, wipe the blade with anoily rag. For rust, use steel wool.

When choosing a band saw blade for acontour cut, consider the tightest curvethat the blade will turn. (Jse the chartat left as a rough guide. In general, thenarrower the blade, the tighter the curve,given the same blade set. But becausewider blades resist unwanted deflection,a narrow blade is not always the bestchoice for a curved cut. A good rule ofthumb is to use the widestblade for thetightest curve required. The limitationson a blade's turning capacity cannot beignored. Forcing a blade around a cornerthat is too tight will cause it to bind inthe kerf, twist and, ultimately, snap.

l\ f uch of the curved wood thatlVl sru..r well-made frrrniture is cuton theiand saw, which can produce vir-tuallv anv contour. As shown in thepagei that follow, you cut curves in avariety of ways: by sawing freehand alonga cutting line, by making use of a pattern(page 90) or by relying on shop-built jigs.

Whatever the shape of the curve, thebiggest challenge in contour-cutting isavoiding dead ends, where the workpiecehits the throat column before the end ofa cut. When this occurs, you have to veeroffthe cutting line and saw to the edgeof the workpiece, or turn offthe saw andback the blade out of the cut. In eithercase, you must choose a new startingpoint for the cut. The key to avoidingsuch pitfalls is to visualize the cut before

CUTTING CURVES

vou make it so you can select the bestitarting point. If a dead end seemsunavoidable, mark cutting lines on bothsides of the workpiece. Occasionally,starting a cut on one side of a workpieceand finishing it on the other is the onlyway to make a cut.

On many contour cuts, making aseries of straight "release" cuts throughwaste areas as illustrated below will greatly facilitate the procedure. Ifbacktrackingout ofa cut is unavoidable, try to startwith shorter cuts and back out of these,rather than beginning with the longercuts. For particularly tight curves, drill ahole at the tightest curves and then cutto the hole along the marked cutting line.

One of the peculiarities of the bandsaw is that its blade will readily follow a

For greater control and accuracy,start a curve with a cut that runs acrossthe grain rather than with it. Whenentering a curve from a straight cut,remember to reduce feed speed slightlyto help ensure precision.

CUTTING A CURVE FREEHAND

1 Making release cuts and starting the curved cutI To keep the blade from binding in the kerf of a curvedcut, make a ser ies of straight release cuts from the edge ofthe workpiece to the cutt ing l ine. The exact locat ion of thecuts is arbitrary, but try to make them to the tightest parts ofthe curve, as shown. To start the curved cut, align the bladejust to the waste side of the cutting line. Feed the workpiecesteadi ly into the blade using your r ight hand, whi le guiding i twith your lef t hand (above). Make sure that nei ther hand isin l ine with the blade.

r) Finishing the cutL fo cutthe tightest parts of the curve, pivot the workpieceon the table, shifting your hand position as necessary. For thecut shown, saw to the end of the curved portion of the cuttingl ine, feeding with your lef t hand. Pivot the workpiece with yourr ight hand to avoid twist ing the blade; veer off the cutt ing l ineand saw to a release cut, if necessary. Keep two fingers of yourr ight hand braced against the table to maintain control of thecut (abovd. Turn the workpiece around and cut along thestraight port ion of the cutt ing l ine.

STRAIGHT CUTS

w:'kf.T*?iil:#,ffi:*: llfi llll-ffi lll llll'llll ll|l llll llll1ll llll llll llll llll llll llll llll llllmachines, the band saw is the ideal shoptool for resawing. Whereas a 10-inchtable saw would take two Dasses to resawa 6-inch-wide board, a standard l4-inchband saw can make the same cut in asingle pass.

Because the band sawblade is relativelythin, it produces a narrower kerf-and leswaste-than is possible with a table orradial arm saw Resawing can be done free-hand, but for more precision, use a pivotblock and a featherboard (page 96).Theband saw is also an excellent choice for rio-ping narrow or round stock (page 95).

Because the thin, flexible band sawblade has a natural tendency to pulseback and forth and sway from side toside imperceptibly as it cuts, you willneed to keep your machine carefullytuned to get smooth and accurate cuts.Without such fastidious maintenance,crosscutting and ripping will be imprecise.

Band saw blades also have a tendencyto "lead," or veer away from a straightline during a cut. This effect can be min-imized by reducing feed speed and usingsharp blades that are properly tensionedand tracked (page BB).

Although more pronounced withnarrower blades, some blade lead is gen-erally unavoidable. However, the lead ofa particular blade is usually constant andpredictable, so you can usually angleyour rip fence to compensate for it.

Crosscutting is a safe procedure onthe band saw. But remember, one of theshortcomings of this machine is thatcrosscutting is limited by the width of thethroat: typically 10 to 14 inches on a two-wheel consumer-grade tool.

RIPPING

Ripping a boardPosition the rip fence for the width of cut, adjusting its angle to compensate forblade lead. Butt the workpiece against the fence and feed i t steadi ly into the bladewith the thumbs of both hands (above). To maintain proper control of the cut, strad-dle the fence with the fingers of your left hand and keep three fingers of your righthand braced on the table.

The board shouldrest flush against the front edge of thesaw table. Ensure that the fence willpivot when the wing nut is loosened.

To use the fence, first mark a lineon the table for the blade lead (page94). Hold the suppod board in posi-tion, then loosen the wing nut to pivotthe fence and align its edge with themarked line. Tighten the wing nut,then clamp the fence in place. Feedshort or narrow stock, as shown, usinga push stick.

Then, screw the two cut pieces side-by-side to a base of solid wood or 3/q-inchplywood to form a V. To provide clearancefor the blade when using the j ig, makea cut halfway across the center of the Vand the base.

To make the rip cut, slip the blade throughthe c learance cu t , then c lamp the j igto the table. Feed the cyl inder into theblade using the thumbs of both hands(left).

ANGLEAND TAPERCUTS'f) y setting the band saw's miter gaugel)at an angle or tilting the saw tableyou can make precise angle cuts, such asmiters, bevels and tapers. For a miter cut,use a sliding bevel to set the miter gaugeto the desired angle-the gauge canbe turned uo to 90"-and then make thecut as you would a standard crosscut(page 97). For best results, make a testcut, check the angle of the cut edge

with a square and adjust the miter gaugesetting, ifnecessary.

For a bevel cut, tilt the table to thedesired angle-band saw tables tilt up to45o to the right and 10o to the left-and,for a cut along the grain, install the ripfence on the righrhand side of the blade.This will position the workpiece on the"downhill" side of the blade, keepingthe workpiece-and your hands-from

slipping toward the blade for a safer cut.For more accurate cuts, adjust the angleof the rip fence to compensate for bladeIead (page 94} Then, cut the bevel as youwould a standard rip cut. The simplesetuDs shown below can be useful formaking multiple miter and bevel cuts.

Thper cuts can be made freehand, butfor several identical pieces, using a jig(page 99) guarantees uniform results.

MAKING REPEAT ANGLE CUTS

Then, screw a board to the gauge as an exten-sion and cut of f the end to the lef t of the saw blade. Glue asandpaper str ip to the extension to minimize the chance ofthe workpiece's sl ipping during a cut. Use the extension as aguide to cut the f i rst miter, then make the miter cut on oneend of a stop block. To cut the second miter, mark a cutt ingl ine on the leading edge of the workpiece. Holding the work-piece flush against the miter gauge, align the cutting line withthe blade and butt the stop block against the end of the work-piece.

CUTTING DUPLICATE PIECES

I n effective method for producingA multiple copies of the same shape isto fasten layers ofstock together and cutthe pieces in one operation with a tech-nique known as stack sawing. Not onlyis it faster than cutting all the pieces sep-arately; it also ensures that each piece isa precise copy ofthe original pattern. Themethod is possible because of the band

TWO SETUPS FOR DUPLICATE PIECES

saw's unique capacity to cut through verythick wood. With a 6-inch deoth of cut aband saw can cut *rou$ as many as ei$tpieces of %-inch plywood in a single pass.

To bond the layers of wood togetherin preparation for the cut, some wood-workers drive nails through the wastearea; others use clamps. Both methods,however, can be hazardous ifthe blade

accidentally strikes a nail or a clamp. Asafer way is to use double-sided tape tohold the pieces together temporarily.

A stop block on the saw table will alsosave time when you are crosscuttingrepeatedly to turn out duplicate pieces.With the setup shown below, you canspeed the job of cutting a cylinder intoidentical slices.

Stack sawingFasten the pieces together in a stack, then mark a cutt ingl ine on the top piece. Before turning on the saw, make surethat the blade is perfect ly square with the saw table (page84); any error wi l l be compounded from the top to the bot-tom of the stack. To cut the stack, first make any necessaryrelease culs (page 89. For the curve shown, align the bladejust to the waste side of the cutt ing l ine, then use the thumbsof bo th hands to feed the s tack s tead i l y a long the markedpalh (above). Keep your fingers on the edges of the stack andbraced on the table to keep them safely away from the blade.

Using a stop blockMake a V-block with a miter bar as you would to crosscuta cyl inder (page 97). To produce several ident ical pieces,insert the V-block miter bar into the miter s lot and clamo astop block to the table so that the distance between the stopb lock and the b lade equa ls the des i red cu t -o f f leng th .

ANATOMY OF A DRILL PRESS

T-\ till presses come in various modelsLJ andsizes, but the basic design is thesame: A steel column 3 or so inches indiameter serves as a backbone to supporta table and a motor that drives a spindle.The spindle is attached to a geared chuckwhose jaws grip the shank of a drill bit orone of a variety of other accessories.

On some models, spindles are inter-changeable. The standard spindle is mat-ed to a chuck with aVz-inch capacity,which means that its jaws can acceptshanks ofdrill bits and accessories up toVzinchin diameter. Other spindles allowttre drill press to accept router bits, mold-ing cutters and mortising attachments.

The column is held upright by aheavy base, usually made of cast iron.For extra support and stability, the basecan be bolted to the shop floor, but the

weight of the drill press is normally ade-quate to keep it stationary.

The two most common tfpes of drillpresses are the floor model and thebench variety. The distinguishing featureis the length of the column: Floor modelshave columns from 66 to 72 inches high,whereas bench models ranqe from 36to 44 inches.

Since the table of a drill press can bepositioned anywhere along the length ofthe column, floor models can handlelonger workpieces. However, you can-tosome extent-overcome the limitationsof a bench-model drill press simply byswinging around the head of themachine. With the spindle extendedbeyond the edge ofthe workbench, theeffective column length is the distancefrom the chuck to the shop floor.

While most drill presses have tables that tilt, the radial arm drillpress features a head that rotates more than 9tr right and left.Such tools can perform jobs impossible on conventional drill presses,including drilling through the center of a j2-inch-diameter circle.

SETTING UPAND SAFETY

T ike any stationary power tool, theI-l drill press has to be kept in adjust-ment to perform well. Before switchinga machine on, check it carefully. Makesure all nuts and lock knobs are tight-ened. Even if you bought your machinenew, there is no guarantee that it is per-fectly ready to run. Check regularly thatthe table is square to the spindle.

SETTING THE DRILLING SPEED

SOUARING THE TABTEAligning the tableInstal l an 8- inch-long steel rod in thechuck as you would a drill bit (page 111),then raise the table unt i l i t a lmost touch-es the rod. Butt a try square against therod as shown; the blade should rest flushagainst the rod (right). lt there is a gap,remove the alignment pin under the tableusing a wrench (inset). Loosen the tablelocking bolt . Swivel the table to br ing therod flush against the square, then tightenthe locking bolt . (Since the holes for thealignment pin will now be offset, do notreinstal l the pin. The locking bolt is suff i -c ient to hold the table securely in place.)

There are also adjustments that have tobe made depending on the particular jobat hand, beginning with setting the &illingspeed. The speed is changed either byturning a knob or by shifting the positionof the belt-or belts-that connect themotor pulley to the spindle pulley.

The drill press has a reputation as a"safe" machine, and there is no denying

that machines such as the table saw andjointer account for a greater number ofserious accidents. Nevertheless, it is pos-sible for even seasoned woodworkers tohave accidents on the drill press. Unlikethe table saw, a drill press will not kickback, but it can grip a small workpieceand send it spinning out of control if thestock is not clamped properly.

Changing belt position and sefting belt tensionLoosen the belt tension lock knob and turn the belt tensionlever counterclockwise to shift the motor toward the spindle pul-ley and slacken the belts. To set the desired rpm, position eachbelt on the correct steps of the pulleys, taking care not to pinchyour fingers. (lf your drill press has a drill ing speed chart on theinside of the belt guard, refer to it in selecting the correct speedfor the drill bit diameter you will be using and for the type andthickness of stock.) To set the belt tension, turn the tensionlever clockwise while pressing the belt connected to the motorpulley until it flexes about 1 inch out of line (left). Tighten thebelt tension lock knob. Do not overtension the belt ; this canreduce belt and pul ley l i fe. Undertensioned belts may sl ip.

BITS AND ACCESSORIES

-f h. range of accessories for the drillI press is a testament to its versatility.

In addition to a variety of sandingattachments, there are also bits for&illittg t/az-inch holes, fly cutters for cut-ting 8-inch circles and plug cutters formaking plugs and dowels.

Most drilling is done with twist orbrad-point bits. Both consist of a cylindri-cal shanh which is held in the jaws of thechuc( and spiral-shaped grooves, knownas flutes. The grooves allow waste chipsand sawdust to escape from the hole, pre-venting overheating. The actual cutting isdone by either sharp spurs or a cutting lip.

As with any cutting tool, drill bitsmust be sharp to work well. And like asaw blade, a drill bit is actually more dan-gerous when it is dull. A blunt bit hastrouble digging into a workpiece andtends to heat up quickly, scorching thewood and the bit. Overheating can alsoresult if drill bits are dirty or gummed up.Clean them with fine steel wool.

For any accessory you install in thedrill press, be sure to remove the chuckkey after tightening the jaws; otherwise,you risk launching a dangerous projec-tile onceyou turn on the machine. Somekeys have a spring at the end of thegeared segment. Pressure is requiredwhen inserting the key; once you let go,the key ejects automatically.

STRAIGHT AND ANGLED HOLES

f, quipped with its tiltable table, the drillL press can bore holes at virtuallv anvangle. The steeper the angle, however, themore difficult it is for a brad-point or twistbit to dig into the stockwithout skating.Choose a Forstner or multispur bitwhendrilling holes at a very steep angle; both ofthese cutting accessories feature guidingrims that provide cleaner penetration.

TECHNIOUES F(|R BASIC DRILLING

Before drilling, make sure that thedrillbit is lined up over the hole in thetable: Otherwise, you risk damaging notonly the bit but also the table itself. Forfurther protection, some woodworkersalso clamp a piece of wood to the drillpress table.

For good results you will need to findthe right combination of drilling speed

(page 108)and feed pressure-the rate atwhich you lower the bit into the stock.Too much speed or feed pressure cancause burn marks on the workpiece andbiq too little will dull the bit's cuttingedge. With the proper combination, youshould be able to cut steadily withouthaving to put undue pressure on theouill feed lever.

Setting up and drill ingTo avoid spl interi ng-particu larly withplywood or particleboard-clamp a sup-port board to the table and set the work-piece on top of i t . Mark a start ing pointon the workpiece and al ign the bi t overit. Rotate the feed lever steadily to feedthe bit into the workpiece; use only enoughpressure to keep the bit cutting (/effl.Retract the bi t occasional ly to clear thehole of wood chips, and i f the machinelabors or the wood stafts to smoke, reducethe feed oressure or cut back on thedrilling speed (page 108).

POCKET H(IIE JIGPocket holes are commonly used withscrews to attach rails to a tabletop,They are drilled at an angle and solvethe problem of having to screw straightthrough a 3- or 4-inch-wide rail. Apocket hole jig (left, fop), shop-builtfrom %-inch plywood, makes simplework of such openings. For the jig,screw the two sides of the cradletogether to form an L. Then cut a 90'wedge from each support bracket sothat the wide side of the cradle willsit at an angle about 15'from the verti-cal. Screw the brackets to the jig baseand glue the cradle to the brackets.

To use the jig, seat the workPiecein the cradle with the side that willbe drilled facing out. Bore the holesin two steps with two different bits:Use a Forstner bit twice the widthof the screw heads for the entranceholes and a brad-point bit slightlywider than the width of the screwshanks for the exit holes. (The widerbrad-point bit allows for wood expan-sion and contraction.)

To begin the process, install thebrad-point bit and, with the machineoff, lower the bit with the feed lever,then butt the end of the workpieceagainst the bit. Position the jig toalign the bit with the center of thebottom edge of the workpiece (inset).Clamp the jig to the table and replacethe brad-ooint bit with the Forstner bit,

Holding the workpiece firmly inthe jig, feed the bit slowly to bore theholes just deep enough to recess thescrew heads. Then, install the brad-point bit and bore through the work-piece to complete the pocket holes(left, bottom).

DOWELS, PLUGS AND TENONS

f-\ owels are 2- to 4-inch-long woodI-r' cylinders used to reinforce simpleconstructions such as butt joints inwhich two pieces of wood are buttedtogether and held in place with glue. Bydrilling perfectly aligned holes in bothpieces of such a joint and inserting dow-els, you greatly strengthen the joinery.Another variation is the integral tenon,which looks and functions like a dowelbut remains part of one of the woodpieces being joined.

The plug-a shorter cousin of thedowel-serves to conceal counterboredscrews. Dowels and plugs can be cutfrom either softwood or hardwood. Thedifference between them-other thantheir length-is that dowels are cut fromend grain to give them cross-sectionalstrength. Plugs, on the other hand, are

not subiect to any radial stress and can becut either with or against the grain. Theycan either be concealed or used as a dec-oration depending on whether they arecut from the same stock as the workpiece.

Dowels of various diameters and in3- or 4-foot lengths are widely availablewherever wood is sold, but you can make

your own if you outfit your drill presswith a dowel cutter. The best way tomake plugs is to cut down a dowel or touse a plug cutter. Wth the latter acces-sory you can either cut through stockthe same thickness as the plug or bore astopped hole through thicker stock andpry the plugs out with a chisel.

'l

An integral tenon makes 0 strongjoint and is relatively easy to cut. Thetenon is produced with a dowel cutterat the end of a square piece of stock.

MAKING DOWELS AND INTEGRAT TENONS

Using a dowel cutterTo cut dowels, clamp a block of woodto the table and bore into its end grainto the required depth with a dowel cutter(far left). Free the dowels by cuttingthrough the block with a table saw or aband saw. lf you will be using the dowelsfor joinery, crimp their ends with the ser-rated jaws of plrers; this will provide theglue with an escape route and ensureproper glue coverage.

To cut an integral tenon on a longworkpiece, t i l t the table 90' and clampthe workpiece to the table, using pads toprotect the wood. Also clamp a supportboard to the workpiece and to the table.Use a dowel cutter to bore to the requireddepth (near /eft), then saw away thewaste to expose the tenon.

MORTISING TECHNIQUESQ ince the time of ancient EgYPt,r.) woodworkers have relied on themortise-and-tenon joint to connectpieces ofwood. Today, the joint is com-monly used to join rails to legs on desls,tables and chairs. Like most joints, themortise-and-tenon can be cut by hand.But for ease and efficiency in carving outmortises, the drill press equippedwith amortising attachment has become thetool of choice. The attachment consistsofa bit that rotates inside a square-edged

A typicat mortising attachment consists of a chiselholder (l), which is secured to the drillpres quill

by machinebolts at the top of theholder' The fence(2) and the hold-down bracket (3) on the table are

Chisels come in different sizes to cutmortises in a variety of widths. Thedepth is set with the drill press depth-stop; 7a-inch is typical. As shown onpage I20, it is important to make surethit the attachment is adjusted to keepthe workpiece square to the chisel. Ifyou are cutting the mortise in round

stock, use a V block to hold the work-piece securely in place.

The drilling speed (Page 108) formortising depends on both the tYPeof stock and the size of the chisel. Thelarger the chisel, the slower the speed,especially when you are drilling intohardwood. For a /r-inch-wide mortisein hardwood, for example, set uP for aspeedof 1200 rpm; for softwood, set up to1500 rpm-or even higher ifyou are cut-ting against the grain.

THE DRILL PRESS AS SANDER

f-\ rill presses make excellent sanders.L) The machine's table provides goodsupport for the workpiece, holding it at90o to the sanding drum to producesanded edges that are square to adjacentsurfaces. Andwith help from some sim-ple jigs, the drill press can sand not onlystraight surfaces but curved ones as well.

Sanding drums come in diametersranging ftomYzto 3 inches. The shaft ofa drum is inserted into the jaws of thechuck and secured in the same way thatdrill bits are installed. Sanding sleeves tocover the drum are available in a varietyof grits-from a coarse 40 grit to a fine

220 grit. In most cases, sleeves arechanged by loosening a nut at either thetop or the bottom of the drum, whichreduces the pressure and releases thesandpaper. Remove the old sleeve andslip on the new Tightening the nut willcause the drum to expand and grip thesleeve securely.

As with standard drilling operations,sanding requires a variety of speedsdepending on the job. The higher therpm, the smoother the finish, but highspeeds will also wear out your sleevesmore quickly. Most sanding is donebetween 1200 and 1500 rpm. Sanding

produces fine dust so remember to weara dust mask.

In addition to sanding, the drill presscan double as a router, although its rel-atively slow spindle speed keeps it fromperforming as well as its portable coun-terpart. While a drill press generatesroughly 3500 to 4500 rpm, a router tumsat more than 20,000 rpm, producingmuch smoother results.

To use your drill press as a router,you will need to buy a special spindleto attach router bits to the machine.Feeding the stock slowly will help com-pensate for the machine's slower speed.

compared to the table sawor band saw, but any wood-worker dedicated to precisionand craftsmanship will attestthat using this surfacing toolproperly is the first step inturning rough boards intowell-built pieces of furniture.The machine's main purposeis to shave small amounts ofwood from the edges and facesof boards, yielding smooth,

IONTER

With aV-block jigclampedto thejointer infeed table, you can cut beveled edges

into a workpiece accurately and safely.

Although the jointer's prin-cipal role is in surfacing oper-ations, using it for nothingmore than thatwouldbe eouiv-alent to restricting the tiblesaw to simole cut-off work.The jointer is also useful in sal-vaging warped stock (pageI35) as well as in shaping rab-bets, bevels and tapered legs(pages 1j6-38).

Jointers are categorizedaccording to the length of theircutterhead knives. In practical

straight and even surfaces from which all subsequent measure-ments and cuts are made. The jointer gets its name from thefact that two edges run across its planing blades should fittogether perfectly, forming a seamless joint.

Enors at the jointing stage of a project will have a ripple effectin all later procedures. Without a perfectly square edge to setagainst a table saw rip fence, for example, trimming a board tosize will produce a flaw that will be further compounded whenyou try to cut a precise-fitting joint.

Traditionally, the task of creating smooth, square edges wasperformed with hand planes, a painstaking proces that depend-ed on skill and experience. Nowadays, woodworkers rely on thejointer to do the job more quickly, effortlessly and accurately.Nevertheless, it is useful to consider the workings of a handplane when visualizing how a jointer is intended to work. Themachine functions much like an inverted hand plane withsomewhat larger blades driven by a motor, addressing the work-piece from below rather than above.

terms, this length determines the width of the jointert table and,more importantly, the maximumwidth of cutthatthe machinecan make. Sizes for consumer models range from 4 to 8 inches;6- and 8-inch jointers are the most popular. Depth of cut, whichranges from Vatoyzinch, is another distinguishing feature. Butunless you plan to make frequent use of the jointer's rabbetingcapabiliry a shallow depth of cut is adequate: The typical bitefor a surfacing pass seldom exceeds t/a inch.

When choosing a jointer, look for a machine on which thetables on both sides of the cutterhead are adjustable. And makesure the machine has a rigid, lockable fence that can be tiltedfor angle cuts.

The jointer is often confused with the planer (page 139),butthe two machines are not interchangeable. One important func-tion of the planer that cannot be effectively performed by a join-ter is planing a surface to make it parallel to the opposite surface.Planers can also handle wider stock, important when construct-ing panels such as tabletops.

In addition to smoothing stock or producingsquare edges, a jointer can be used to cuttapers in a workpiece, such as a table leg.

Depth of cut is determined by theamount that the infeed table is set belowthe oudeed table. The fence used to guidestock over the cutterhead is normally setat a 90o angle. But on most models thefence will tilt forward or backward forcutting bevels and chamfers.

SETTING UP AND SAFETY

I ccurate jointing depends on preciseA alignment of the two tables and thefence-the parts of the machine thatguide a workpiece into and over theknives. Begur by ensuring that the out-feed table is at the same height as the cut-ting edges of the knives at their highestpoinr Then check that the tables arc per-fectly square to the fence and alignedproperly with each other.

Before starting, make sure that thejointer is unplugged and install a clamp

onthe rabbetingledge to holdthe guardtemporarily out ofyour way.

Onceyou have the machine properlytuned, pause and consider safety. Theknives of a spinning cutterhead lookseductively benign. It is easy to forgetthat this harrnles-lookingblur can causeas muchdamageto fingers andhands ascan a table saw blade. Resist the tempta-tion to operate the jointer without theguard in place.When the guard mustberemoved from its normal position in

front of the fence for rabbeting opera-tions, install it behind the fence if yourjointer is set up for such a switch.

Even with the guard in place, alwayskeep your hands away from the knives.When jointing the edge of aboard, yourhands should ride along the workpiece,rather than on the tables. When face-jointing, always use push blocls to feeda workpiece across the knives. Whateverthe cut, remember to pres the worlgiecefirmly against the tables and fence.

SETTING OUTFEED TABTE HEIGHT

r) Adjusting the outleed tirble heightI Keepingthe hardwood board over thecutterhead, turn the outfeed table adjust-ment handle (right), raising or loweringthe table until the edge of a knife justbrushes against the board. Then check thetable height in relation to the other knives.

1 Checkingtable heightI Use a small wooden wedge to rotatethe cutterhead until the edge of one ofthe knives is at its highest point, Thenhold a straight hardwood board on theoutfeed table so that it extends over thecutterhead without contacting the infeedtable (left). The knife should just brushagainst the board. Perform the test alongthe length of the knife, moving the boardfrom the fence to the rabbeting ledge.Repeat the test for the other knives. lfone knife fails the test, adjust its heightas you would when installing a blade(page 131). lf none of the knives touchesthe board, adjust the height of the out-feed table (step 2).

JOINTER SAFETY TIPS

. Check regularly to make surethat the knives are sharp and secure-ly fastened to the cutterhead.

. Unplug the jo inter whi leinsta l l ing knives or per formingany setup operation.

. Wear appropriate safety glassesand hearing protection when oper-ating the jointer.

. Do not joint stock with looseknots or the workpiece may catchin the cut terhead.

. Never joint stock that is lessl h a n 1 2 i n n h o c l n n o

. Do not face-joint stock that isless than % inch th ick.

. Do not joint the end grain ofa workpiece that is less than 6inches wide.

. When the machine is running,keep your hands out of the area4 inches above and to either sideof the jointer's cutterhead.

. Never reach up into the dustchute unless the jointer is unplugged

1 Aligning the tablesI Remove the fence, then use the adjust-ment handle for the infeed table to br ingit to the same height as the outfeed table.Use a straightedge to confirm that the twotables are absolutely level. lf the alignmentis not perfect, adjust one or more of thegib screws at the back of the jointer untilthe straightedge rests flush on both tables;remove the pulley cover, if necessary, toaccess the screws. To adjust a screw, firstloosen its locknut, then make the adjust-ment using with a hex wrench (left). Trghtenthe locknut. At this point, the depth scale(page 126) should read "0." lf not, moveihp nnintpr tn thp "O" mark. ReCheCk thetable height @age 128)if you moved theout feed table.

r) Squaring the fence with the tablesL Wttn the fence set in its vertical position, hold a try square on the outfeedtable near the cutterhead and butt the square's blade against the fence. Thesquare should f i t f lush against the fence. l f there is any gap between the two,slacken the fence control handle and br ing the fence f lush with the squarebbove). l f necessary, pivot the metal stop out of the way when making thisadlustment. Then t ighten the handle.

JOINTE,RKNIVES

T T nl ike the blades of other wood-L-/ working machines, whose heightand angle are adjustable, jointer knivesare designed to function at just one set-ting: parallel to and at the same heightas the machine's outfeed table. As such,the height of all the knives must beidentical; a difference of as little as afraction of an inch can comoromise thejo in te r ' s -ab i l i t y to p roduce smooth ,square eoges.

Like all blades, jointer knives workwell only when they are sharp. However,because removing a jointer knife forsharpening and then reinstalling it prop-erly can be a time-consuming operation,many woodworkers go to great lengthsto avoid changing these blades. It is pos-

sible to use an oilstone to hone the cut-ting edges of slightly dull knives whilethey are in the cutterhead. But you riskremoving more metal from the cuttingedges than is absolutely necessary andthis can throw the knives out of align-ment with the outfeed table.

There are tricks you can use to pro-long the usefi.rl life of a set of knives (pagel3l), but once your rnachine begins pro-ducing uneven limp shavings or bur-nishing lhe wood, i t is t ime to removethe knives and have them reground. Besure to give the person doing the sharp-ening explicit instructions regarding thesame amount of steel to be removedfrom each knife. Otherwise, the cutter-head may become imbalanced, causing

machine vibration and also possiblemotor failure.

When changing your jointer knives,remove and reinstall them one at a time.Taking the blades all offat once and theninstalling them one after another can putstress on the cutterhead,

Ifyou are considering replacing theknives, you can choose between highspeed steel or tungsten carbide. The car-bide variety offers superior performancein cutting abrasive materials such as ply-wood; they cost more, however. Alwaysreplace the entire set ofblades, ratherthan individual knives. In the meantime,keep your knives clean by rubbing themoccasionally with a cloth dampened inturpentine or lacquer thinner.

IOINTING

A n. of the f i rst rules of jo int ing is\,/ that a workpiece should always befed across the cutterhead so that theknives are cutting with the grain, In thisway you will get the smoothest cut whilereducing the risk of splintering or kick-back. Ifthe grain changes direction in aworkpiece, feed the stock so that most ofthe cut is following the grain.

The sequence for jointing operationsshould depend on the wood you are

J()INTING AN EDGE

using. For rough lumber, joint the facesfirst (page 134), then do the edges(below). For wood on which both faceshave already been surfaced, jointing theedges is usually sufficient.

In general, set a cutting depth of 7sinch for softwoods or '/re inch for hard-woods. You can usually joint the edges byhand, but always use a push block toface-joint. Whatever the depth you select,check the setting before making the first

pass. Unplug the jointer and use a scrap ofwood to rotate the cutterhead so that all theknives are beiow the level ofthe tables.Then, place a board flush on the outfeedtable;the gap between the board's edge andthe infeed table will equal the depth of cut.

If most of your jointing involves work-ing with board edges, avoid dulling thesame narrow segment of your knives byroutinely moving the fence over slightlyto evenly distribute the wear.

1 Feedins a workpiece into the cutt -

I Lav the workoiece on the infeed table a few inchesfrom the knives, butt ing i ts face against the fence. Slowlyfeed the workpiece into the cutterhead knives (/eff), press-ing i t aga ins t the fence w i th your le f t hand wh i le mov ingit steadi ly forward with your r ight hand. As the workpiececrosses to the outfeed table, gradual ly shi f t your weightfrom your back foot to your front foot. Cont inue feeding thestock unt i l your r ight hand approaches the outfeed table.

r) Finishing the passI Wnenyour right hand reaches the outfeed table, reverse theposition of your hands while continuing to feed the workpiece.Gradually slide your left hand toward the back of the workpiece(right), mainlaining pressure against the fence. Then shift yourright hand further back on the stock to maintain downwardpressure just to the outfeed side of the knives. Continue thesehand-over-hand movements until the pass is completed.

OUTFEED TABTE ATIGNMENT

Poor results wrth a jointer can often be attributed to mis-al ignment of the outfeed table in relat ion to the cutter-head. Perfect jo int ing depends on the table's being atprecisely the same height as the knives @age 128).Thediagrams above illustrate what can go wrong if the out-feed table is too high or too low-and what should hap-

pen when it is at the correct height. lf the outfeed tableis set higher than the knives, jo int ing wi l l produce a taper(lefil; if the table is too low, the blades will leave a con-cave cut, cal led a snipe, at the end of the workpiece(center). When the table is properly adjusted the resultwill be a smooth, even cut tight).

JOINTING A FACE

Using push blocksMove the fence toward the rabbetingledge, if necessary, so that no portion ofthe knives will be exposed as the work-piece passes over the cutterhead. Lay theworkpiece face-down on the infeed tablea few inches from the knives, butting itsedge against the fence. Then put twopush blocks squarely on top of the stock,centered between its edges. (Use pushblocks with angled handles to keep yourhands from hitting the fence.) Slowlyfeed the workpiece across the knives(left) applying downward pressure on theoutfeed side of the knives to keeo the stockflat on the tables and lateral pressure tokeep it flush against the fence. For a longworkpiece, bring your left hand to the backof the workpiece when your right handreaches the outfeed table.

A PUSH BTOCKInstead of buying push blocks suchas the ones shovrrn above, some wood-workers prefer to make their own.Refer to the illustration at right forsuggested dimensions, although youcan tailor your design to the work-piece at hand.

Glue the lip to the underside ofthe base, flush with one end, Thenposition the handle on the top of thebase so that its back end is flushwith the end of the base. Screw thehandle to the base, driving the screwsfrom the underside of the base.Countersink the screws to avoidscratching the workpiece when youuse the push block. Bore a holenear the front end of the base so

you can hang the push block on thewall when it is not in use.

Use the push block as describedabove, but position it on the workpiece

so that the lip hugs the trailing end ofthe stock. Position your left hand onthe workpiece near its front end, brac-ing your thumb on the push block.

SALVAGINGWARPED STOCK

I lthough the jointer's principal valueA rests in its ability to smooth andsquare rough wood surfaces, it can alsostraighten out stock with other defects.The jointer is also useful for evening outboards that have concave (inward-bow-ing) or convex (outward-bowing) faces.The diagrams below show how to correctboth types of irregularities.

In each operation, the high spots onthe wood surface are passed repeatedlyacross the cutterhead until they areremoved. For a convex e dge (below,left),pass the high spot at the middle of theboard repeatedly across the cutterhead asmany times as necessary (cuts 1 and 2).Try not to 'hose-dive" or to allow the lead-ing edge to ride up while you are cutting.

When the surface is roughly even, makea final pass along the entire edge (cut 3).

For a concave edge, pass the high spotat one end ofthe board across the knives(below, right) as many times as necessary(cuts I and 2), then turn the boardaround to repeat the process at the otherend (cuts 3 and 4).When the surface isroughly even, make a final pass (cut 5).

Angled cuts along the corners of aworkpiece, known as chamfers, are madeon the jointer by tilting the fence to therequired angle or with the aid of a shop-made jig. Tapers are also straightforward.With a stop block clamped to each table,you can cut stopped tapers that leavesquare ends for joining to a tabletop orseat, or for carving into a decorative foot.

RABBETS, CHAMFERS AND TAPERSith a little resourcefi;lness, you cando more than produce square

PLANER

N or smoothing rough stock, planing aI 'g lued-up panel or reducing thethickness of a board uniforrnly, the plan-er is the ideal woodworking machine. Itsmain function is to plane wood from aboard, producing a smooth surface thatis parallel with the opposite face.

Planers are easy to use, but keep thefollowing points in mind to get the bestresults. Always feed stock into the knivesfollowing the direction of grain. Al-though the maximum depth of cut formost planers is 7e inch,limit each pass to%o inch and make multiple passes.

Some of the tasks you perform onthe jointer cannot be duplicated onthe planer. You cannot, for example,straighten out a warped board. Since theplaner produces parallel surfaces, waqpedstock will emerge thinner from themachine, but just as warped.

To make apass through the planer, stand to one sideof the workpiece and use both hands tofeed it slowly into the infeed roller, keep-ing its edges parallel to the table edges.Once the infeed roller grips the workpieceand begins pulling it past the cutterhead,support the trai l ing end of the stock tokeep it flat on the table (left). As the trail-ing end of the workpiece reaches the plan-er's table, move to the outfeed side of themachine. Support the workpiece with bothhands until it clears the outfeed roller. Toprevent stock from warping, plane fromboth sides of a workpiece rather thanremoving thickness from one side only.
