Finally built a new Box Joint Jig for the new/used table saw I purchased this past year. Nothing fancy, base is 24" x 12" the jig was made from cabinet grade 3/4" plywood scraps form the job site, and oak runners. Dado cut is set for 1/4"
I made a couple of other boards to make box joints in either hexagon and octogon. All board faces have a strip of 150 grit paper glued in place to help with a grip.
Planning on making a few more, one for 1/2" joints and one for 3/4" joints.
These should come in handy making small boxes, and with multiple sides that I like to make.
