Types of Wood JointsButt JointThe simple butt joint is most commonly used. This joint is formed by nailing or screwing the end of one piece of wood to the end of the other. While this is simple, fast and effective, the butt joint leaves the heads of the screws or nails exposed.Used in cabinet making or Construction framing
The dowel joint is basically the same as the butt joint except dowels are used to hold the two pieces of wood together instead of screws and nails Construct blind dowel joints by drilling the holes only partway into each piece of wood. Then drive the dowels into these holes and glue them into position. The dowels are not always visible.
