Butt joint

The simplest method for joining two pieces of wood to form a corner is called a butt joint (Fig. 609). It is formed very simply by overlapping the end of one piece over the end of the other.

To have any strength at all this joint must be fastened, first with glue and then with screws or nails.

This is the simplest type of joint, but also the weakest. All that is required to make a reasonably tight clean joint of this type is a good straight smooth cut on each of the ends to be joined. No special machining is required. Ends satisfactory for butt joining can be done with very modest equipment, making this the joint of choice when facilities are limited.

The disadvantage of the plain butt joint, in addition to weakness, is that the entire end grain of the overlapping piece is exposed. It is impossible to finish this end grain so that it will conform to the lengthwise grain of the rest of the side. If veneer-cored plywood has been used, the end grain can be particularly obnoxious.
