Several months ago at an auction, I bought a belt grinder. A Craftsman belt grinder. It featured a 1" x 42" belt and an 8" disc sander. I got it at a good price and thought that, being a Craftsman I could run to Sears and get belts for it.
Not so fast. When I went to Sears, they looked at me like I'd grown a tail. Evidently they haven't sold this belt grinder in several dozen years. So, I went over to Ace Hardware. No luck, no joy. The other day I was in Lowe's and wandered through their abrasives. I spotted two packs of 1" x 42" belts, so I picked them up, then I found some 8" discs. I picked those up too.
