Rodger, I forgot to mention that this technique will only leave a very small hole in the center of the bottom of the circle. I just remembered that a technique used by David Marks on Woodworks was similar. He used the previous described technique to cut a pattern piece out of some 1/4" mdf or a similar material. He then fastened it to the good plywood using double face tape. Now with his router and a pattern cutting bit, he traced and cut the finished plywood. This left no nail hole in the finished piece.

Using a table saw I read about this procedure which seams fairly easy. For example you want a 3'diameter top. you make a support that will be clamped to the table of the saw with a small nail protruding 18" from one end. Now this support arm is positioned so that the nail is 18" from the blade. This is the radius of the circle. Now place your plywood on the nail with the blade lowered.As you slowly raise the blade while spinning the plywood the pivot you will cut a perfect circle. A similar technique may be used with a router table and If using hand held cutters then you would cut from the top and use the pivot arm to support the router or saw I thought that I saved the original information but my magic fingers took care of that. I will try and find it for you.

I have all the saws and tools for most things but am still learning from your shows how to use them in different ways. I need to make a few different jigs for different shapes and could enjoy hearing from you on how to make them. Thanks for your helping advice.
