When I was making a 32" round table top out of 6/4 maple I made this jig. It is simply a piece of 1/2" plywood with a couple of pieces of scrap fastened on to fit the Table Top of the saw. I drilled holes in it so that I can make tope from 2" to 48". The holes are every 1/2" apart close in and 1" apart further out. I use a pop rivet to hold the piece in place and then just spin away. Works great for making blanks for the lathe too.
