Joint

Box joints—also called finger-joints—are a wonderfully strong and versatile joint. Often called the machine equivalent of the dovetail joint, the box joint is used for everything from pencil boxes to drawers and case construction. Once your table saw is set up properly, the actual work of cutting the joint goes very quickly.

Our Super Box Joint Jig combines versatility with accuracy and ease of use. Using a system of either single or multiple brass keys, the jig will cut box joints in '/k> in. increments from '/» in. all the way up to l⁵/w> in.—a range that encompasses nearly every possible use. Since brass stock isn't usually available at your local hardware store, we've arranged with a kit supplier to put together a hardware kit that includes not 44

And, if the top-quality multi-layer All-Birch plywood we used isn't sold locally, a plywood kit is available that includes all the plywood and Ma-sonite that you'll need (see Kit Sources).

Our super jig is a quantum leap away from the typical shop-made single-purpose box joint jig. where you made a wooden key for a specific size finger, glued it into a board, and then screwed the board to Ihe miter gauge. With this old-fashioned jig, it was critical to locate

the board so the key was exactly one key width away from the blade. There was no built-in adjustability in the jig, and if the initial set-up wasn't perfect, your only option was removing the screws and relocating the jig. Given the problems this can email, plus the difficulties that arise when the wooden key begins to fray or wear, it's not hard lo understand why so many hobby woodworkers seem to shy away from the box joint.

The Super Box Joinl Jig takes much of the fuss out of the set up process. But even more important, by including a The Woodworker's Journal
