Mostly pics, it’s pretty self explanatory:
My pieces are long so it has to be tall:
And it’s dead nuts 90 degrees to my table saw top:
I am thinking of adding a foot on the opposite side (to the blade) of the jig that will slide on my table top (with a little wax) and give the jig a little more vertical stability.
I already have an idea to modify it for angled tenons. I’ll give that a try sometime …
