How to Build a Box Joint Jig

Resources

Tom uses an old milk crate that has a series of box joints to demonstrate the amount of glue surface that the joint creates. Each of these “fingers”, as Tom calls them, presents more gluing surface, and therefore more holding power. Building the joint can be done on either a router or a table saw.

Tom decides to use a table saw equipped with a dado blade. He and Kevin build a box joint jig which is a simple table saw sled equipped with adjustable stops and a pin. The pin allows for even spacing between dados. Tom and Kevin use black walnut to make the tray, which they sand, assemble, and then finish with food-safe oil.

Materials

1/2 inch pine stock (for the sled) 1/2 inch walnut stock Wood glue Painter’s tape Food-safe oil
