I enjoyed Patrick Warner's article on the box joint (Fine Woodworking #14, Jan.'79).I like the visual results, strength and ease of assembly the joint allows.Like Warner, I use a router to cut box joints, but my technique is different.
I have installed a guide block on the base of my router that acts as a jig for accurately spacing the finger cuts.The setup does not limit me in width, angle or length of project.I have made jigs to fit several common-size router bits but I usually prefer the 1/2-in.
setup for most work.The sketch shows how to mount the guide block for 1/2-in.cuts.The accuracy of the joint depends on how carefully you position the guide in relation to the bit.Drill the scr*w holes in the router base a little large to give yourself some adjustment room...
