I wanted to try out some box joints on my router table so spent a little time designing a jig. It struck me that I might want to do more than one size of box joints but I didn’t really want to build 2 jigs. I noticed that the router bit is not centered in the table and so I could combine both a 1/4” and 1/2” jig in one. It took a few test pieces to figure out the pin system but both sides work great. The 1/4” side works best on wood that’s 1/2” thick or less, though I’ve tried it with 3/4” with some success—just takes a lot of cleaning up afterwards.
Pics 1-3 are the jig itself
Pic 4 & 5 are PO Box door “safes” (not banks) made using the jig’s 1/2” side (3/4” lumber)
Pic 6 is a frame for a bulletin board made using the 1/4” side (about 1/4” thick lumber)
