Now we're going to discuss four different types of basic wood joints. One of them is a dovetail joint, one of them is a mortise and tendon, another is a lap joint and the last one is forty five degree miter. First we're going to talk about dovetail joints. Dovetail joints consist of two parts, the dovetails and the pins. The pins slide in to the dovetails locking the two pieces together. The next one I'll be demonstrating is the lap joint. Lap joint consist of two pieces of wood with grooves in them half way through the width of the other piece. They interlock by the two grooves facing each other sliding together. If it's a proper fitting lap joint, two sides will be flush fitting at ninety degrees. The next joint we'll be doing is a forty five degree miter joint, where you have a forty five degree and a forty five degree cut on another board. When they're placed together it forms a ninety degree angle. The last joint I'll be demonstrating today is the mortise and tendon. The mortise and tendon is composed of a tendon and a mortise. The mortise being the hole and the tendon being the peg that slides in to the hole. The peg creates a ledge which now can support weight. Using these four wood joints, the dovetail, the mortise and tendon, the lap joint and the spline miter joint, you should be able to work on any kind of project you want whether it be furniture, a framing project or around the house wood work.
