Original poster: "by way of Terry Fritz <teslalist-at-qwest-dot-net>" <JACKBINTHEBOX-at-aol-dot-com> I'm hoping to build an RSG, but I have no idea where I can buy a nice fiberglass disc. Anyone have any idea where I might find one? I've looked at the hardware store, at sanding disks etc., but nothing they have will work. What is everybody out there using? Thanks! Jack
