Making a mortise-and-tenon joint may be a daunting prospect to the novice woodworker, but with the proper tools, shaping the parts is a quite straightforward process. The tenon should be between one third and one half of the thickness of the stock from which it is made. Set your mortise gauge to the chosen tenon thickness, positioning the points so that it will score a pair of lines that distance apart. When using the mortise attachment, the drill press is operated in much the same way as when it performs ordinary drilling tasks.
On the table saw, position the fence so that the distance from the opposite side of the blade to the fence matches the desired length of the tenon.
The spinning bit will do most of the cutting, but the chisel squares off the corners around the hole, producing the shouldered mortise hole.
In cutting accurate mortises, it is essential that the sides of the chisel be square to the stock. Glue is often used to connect mortise-and-tenon joints, as are dowels driven through the joint. When shaped properly, mortise-and-tenon joints can even be decorative elements in the finished appearance of a piece. A perfectly shaped tenon that’s the wrong size or shape is no accomplishment at all.
It can be cut in several ways, among them the traditional approach of using sturdy mortising chisels and a mallet to chisel out the hole by hand. Clamp the pieces together, and insert the dowels, leaving them protruding from both sides of the joint. Another option is to use a Forstner or auger bit on your drill or drill brace to start the mortise, then clean and square it with a chisel.
