Types of Joinery
Mortise and Tenon
Simple and strong, the mortise and tenon joint has been used for thousands of years by woodworkers around the world to join pieces of wood, usually when the pieces are at an angle close to 90°. The end of the first member is called the tenon, and it is usually narrowed with respect to the rest of the piece. The hole in the second member is called the mortise.
A dovetail joint is known for its tensile strength or resistance to being pulled apart. It is used to join for example the sides of a drawer to the front. A series of pins cut to extend from the end of one board interlock with a series of tails cut into the end of another board. The pins and tails have a trapezoidal shape. Once glued, a wooden dovetail joint requires no mechanical fasteners.
Lock Miter Joints
The lock miter is very strong and its advantages are that it is hidden from the outside. It requires clamping in only one direction because of the built in locking action.
