I have made a few zero clearance inserts but thanks. The only real [problem is trying to make a good saw guard. I would also like to see if there is any way to make a riving knife (rides up and down with the blade) but it is an older construction saw not a good cabinet saw, so unlikely, unless there is a genius out there.
