Finger-Joint Jig for the Tablesaw

There are countless ways to cut finger joints (also called box joints). You can cut them by hand, with a router, or on the tablesaw. Over the years, Fine Woodworking has published plans for a variety of jigs to cut them. In issue #214, we featured another one: a dedicated tablesaw sled by Dennis Theisen of Grand Rapids, Mich. The jig is super easy to make (some can be highly-engineered like this one by Matthias Wandel) and cuts one size of fingers. You can easily adjust it using the rear fence face to get the cut dialed in just right.

Give the jig a try. Finger joints are perfect for box joinery, case construction without dovetails, shop furniture, and more. See how to make and use Theisen’s jig in the animation below then follow these links for written instructions and a plan with dimensions.
