Reed and others, I am not sure how much help this is but here is a bad shot of my extensions. I just used some plywood I had laying around and applied a finish to help the wood slide. I did have to cut out a slot for the right side to allow my log mill and other tools to run past the edge of the table. At the back of the table groove on the left side I cut a small hole to allow me to get dust out of the groove.
My saw is located next to a work table which allowed me to rest it on that and in addition I use a bench vise to clamp the whole thing in place. the corner at the right front side has a small section of angle aluminim that I screwed to that table to allow the extension to rest on it.

If anyone is interested in more photos I could take some today and post later.

I think this equates nicely to wood turning as well . . . . .
