Summary: When making woodworking projects, there are different ways to join wood, and each wood joint has a specific use, such as dovetail joints for tabletops, and mortise and tendon joints for benches. Learn about the strongest and weakest wood joints in this free video from an award-winning woodworker on basic carpentry.

"Now, we're going to talk about several different types of wood joints, and how they're actually applied, throughout use in furniture, and other objects. First, we're going to talk about the dovetail. It consists of a dovetail with the pins. The dovetails slide into the pins, locking the two pieces together. Here it is actually applied, within a piece of furniture. This piece right here on this tabletop, will later hinge up and over, creating another surface. The end piece right here, is dovetailed on. Another joint we have, is a mortise and tenon. This is used throughout all of these pieces. In this piece, each one of these cross slats, are mortised and tenoned into this side piece, creating a very strong and rigid structure. In this piece here, there are mortise and tenons, throughout the whole thing. This rail is connected to the legs, along with aprons on the side. Other mortise and tenons, are these through mortise and tenons, on the top of this bench. The legs come up through the seat, and then there's a wedge inserted into the tenon, which expands it, tightening it into it's place. The next joint I'm going to have, is a lap joint. The lap joint is two pieces of wood cut halfway through, that interlock with each other, and create a very strong glue surface. In this small bench, there's a lap joint at the bottom, connecting the two legs with the rail. Yet another joint, similar to a mortise and tenon, is a through peg with a wedge, holding this mahogany handle, on to this maple head of this mallet. One more kind of joint, is just an edge glue surface. This is a solid piece of mahogany, with two mahogany rails, edge glued right to the edge, creating a very strong, long grain, glue surface. As you can see, these basic wood joints can be applied to many aspects with woodwork, tools, boxes, furniture, and other types of woodwork."
