Not having a table saw, I needed an adjustable jig for cutting box joints on my router table. I liked the design by Shop Notes that has been used by several others on Lumberjocks, such as Tyka's posting. The design is for use with a table saw, but with a few small modifications, it works very well with a router table.
My router table didn’t have an adequate miter T-track to use for sliding the jig, so I added 2 parallel aluminum miter T-tracks to my existing Craftsman router table and I added 2 miter T-bars to the bottom of the jig. The original design had a 3/4” thick board on the bottom of the jig to help serve as a ledge for the piece being jointed. On a router table, that increases the distance a router bit would need to extend above the table to an unacceptable height, so I eliminated the board. I purchased the miter T-track, T-bar, and knobs from Peachtree Woodworking Supply. The rest of the metal hardware was 1/2” metal L-brackets and 1/4” x 20 – hex bolts, washers, lock nuts, screw insert nuts, and flat headed “elevator” bolts. The wood was ash.
