I made this tenoning jig as what I thought could be a solution to the 22.5-degree angle required for a flag display case. I have a right-tilt arbor on my tablesaw which necessitates using the jig in reverse—moving the fence to the left of the blade.
Maybe it would work for someone else, but it didn’t work for me for that purpose. I still could not get a correct angle close enough to be worth the bother. I ultimately rough cut the angle on the bandsaw and then sanded it to perfection with this sanding protractor jig that I made.
I hope that I’ll eventually get some use out of it for cutting tenons! Meanwhile, it works really well as a fence for taller pieces.
