A couple of month ago there was a post about a tablesaw dado set tearing plywood. I though I would share this jig as an alternative to routing dados on the tablesaw. What I really like about this jig is that you can clamp matching pieces together to get perfectly fitting dados. I also have a Freud 8" dado set for the tablesaw, but for larger pieces, I like this jig even more. The finished surface had a little fuzz that sanded right off with no tearout. I used a 1/2" straight bit for the routing and made two passes so that I could get just the right thickness for the plywood. One note of caution: make sure everything is clamped down very well. The first time I used it, I only clamped the jig and the piece moved and it messed up my dado.
