INSTRUCTIONS FOR INSTALLA~rION AND OPERATION OF CRAFTSMAN LATHE

MODEL NUMBER 103.21600

- HEADSTOCK COVER HANDWHEEL I

LATHE BED TOOL REST LOCK

FIGURE I

Your lathe has been completely inspected and tested

at the factory. To prevent loss of parts during ship ­

ment, the headstock cover 28711 and the wrench

28714 have been packed separately in the enclosed

carton.

INSTALLATION:

The lathe shoulid be mounted securely on a work

table or bench. Three ¾ holes are provided in the

lathe bed for this purpose.

This lathe is so designed that the motor can be

mounted either bcehind or below the spindle pulley.

In either position,. a hinged motor mount should be

used to facilitate :shifting the belt to different pulley

------- steps for change of speed.

To install the V -belt remove the collar from the

outside end of the spindle, loosen the two pulley set

screws and pull the spindle out of the headstock. Do

not allow the pulley to drop. Install the belt around

the pulley and rein,sert the spindle . Engage the pulley

set screw in the flat provided on the spindle and tighten

securely. Reinstall the collar on the spindle and

tighten its set sc1rew securely, leaving only enough

end play to insure a free running spindle. Install the

headstock cover in position as shown in Figure 1.

Consider directiion of rotation when installing the

motor. The rotsttion of the spur center roust be

counterclockwise when viewed from the tailstock

end of the lathe.

A switch for quick power cut-off is recommended

at the left ha:nd end of the lathe.

LUBRICATION :

Before operating this lathe, fill the headstock bearing

reservoirs witlh. a good grade light machine oil. These

- - oil reservoirs are accessib"Je from the-rea" of ..the_ lathe

through the two oilers X-1900. Use either a pressure

feed or fine spout oil can to more readily displace air

in the reservoir. Keep . the reservoirs filled.

2

The bronze bearings used in this lathe are designed

to absorb andl meter oil to the spindle. These bear­

ings are porous and become saturated with oil. DO

NOT DRILL HOLES THROUGH THESE BEAR­

INGS. The oil reservoirs extend completely around

the bearings thus insuring uniform lubrication. The

ball type thrust bearing 18221. in the headstock has

been packed with grease at the factory and will require

no further attention for the life of the bearing. To

maintain sroo,oth operation of your lathe, a few drops

of light oil may be applied occasionally to the turning

and sliding units in the tailstock.

SPEED: Your lathe w ill give best results under normal con­

ditions, when driven by a H horsepower 1750 ~.P.M.

motor. For c•ontinuous heavy duty work, a½ horse­

power motor of the same R.P.M. should be used. By

using a three step pulley with dimensions similar to

those of the spindle pulley, the following recommended

speeds may be atfained;

Work Diamc,ter R.P.M. R oughing R.P.M. Finishing

Up to 3• 1750 2985

3" to 5' 1025 1750

5" t o 8" 1025 1025

The three step pulley mentioned may be obtained

from your Sears' retail or mail order store. Ask for

stock number 9-2788. Be sure to specify the shaft

diameter of your motor.

CONTRO>LS:

Major adjustment of the distance between the head­

stock and tailstock may be made by loosening the

tailstock 1-ock (Figure 1) until the tailstock may be

moved along the bed to the desired position. The

distance between the centers may be set from O to

24 inches. The tailstock lock should be tightened

securely boefore operation is resumed. Minor adjust­

ment of distance between centers may be made by

turning the handwheel either retracting or advancing

the cup center as desired. The lock handle is pro­

vided to secure the cup center after the proper position

has been selected. Always loosen the lock handle

before tun!ling the handwheel. The tool rest may be

raised and lowered or turned in its pivot after loosen­

ing the toe,! rest lock (Figure 1) with the wrench 28714

- provided. The~roonest and its holder28215 may be

moved to any desired position along the lathe bed

after loosening the clamp nut X-413 with the wrench

provided. The tool rest lock and clamp nut should be

securely tightened before proceeding with turning

operations.

OPERATION :

Parts to be turned between centers should be cut at

least ¾ irnch longer than the finished pieces to allow

material for cut-off after turning. The ends must be

cut square.

Locate and mark the centers of each end. In one

end make perpendicular saw cuts ½ deep through

the center, mark the other end with a prick punch.

Remove the spur center and tap it firmly into the

saw cuts, 1nount the work in the lathe and insert the

point of the cup center in the punch mark. When

clamping the work between the centers tum it by

hand. The piece should be held firmly, but should

rotate freely between the centers. _ Position the tool

rest close to the work piece and just above its center

line. Again turn the piece by hand to insure clearance

before applying power.

3

/ Start cutting in the middle and work toward the

ends until the work piece is round. After the rough

cut ha,s been completed, stop the lathe and adjust the

tool rest close to the work for the sizing and finishing

cuts.

The gouge chisel should be used for rough turning

operations with the top edge of the chisel tilted toward

the direction of cut. The degree of tilt, and amount

of cut will vary with the grain and hardness of the

wood.

Coves, or radial grooves are cut with the round nose

chisel,, while V-shaped grooves should be cut with a

spear point chisel. Finishing cuts are generally made

with the flat diagonal edge skew chisel. The parting

tool, a V-point tool with no bevel is used for cut-off

work, as well as for making sizing cuts for special

shapes and figures. It is sometimes desirable to cut

the work piece off with the parting tool after complet­

ing turning operations. In this case the diameter

at the points of cut-off should be reduced to about

¼ inch before sanding operations are started.

Before sanding or polishing a piece under power

between centers, stop the lathe and remove the tool

rest. When sanding and finishing under power, DO

NOT WRAP PAPER OR CLOTH AROUND THE _

WORK_ PIECE. T.h-is-p:=aetic<; ca~ r:::;;ult in serious

injur)'. ~ ,

Tw·ning operations may be performed on surfaces

of flat: pieces up to 8 inches in diameter. These pieces

may be attached directly to a face plate with short

screws or glued to a wood backing plate attached to

the face plate. When the backing plate is used, a

piece of paper glued between it and the work piece

will facilitate separation after completion of turning

operations. For face plate turning, the tool rest should

be pa:rallel to the work piece. Stop the lathe and re­

move the tool rest before sanding and finishing.

SAFE:TY:

Do not operate this lathe while wearing loose clothing

which might become entangled in the revolving work.

Double check all mounted work for security. Fast

spinning pieces can do serious damage if they break

loose as a result of a careless mounting. Keep the cut­

ting tools sharp and keep the tool rest close to the

work. Do not be afraid of high speeds on ordinary

spindle work.

Accessories for your lathe may be purchased from

your Sears' retail or mail order store.
