17-Feb-08 I found out why the fence will not clamp any more. The top part on the plywood is the original. Took me 5 hours to make the replacement part (for some reason Sears discontinued it). I was able to hold 1/64" after the repair, but it still took fussing with the fence for every setting to do so. I think I could get it to 1/128" if I align the table with the saw blade and figure out why the blade runs crooked on the arbor.
