I've been watching for grinders and lathes for weeks on Craigslist. Just obsessively... constantly. Every day, several times a day. This truly is a waste of time. But one thing is clear. If you're scanning that much, you see deals. Like a late model South Bend Heavy 10, well-equipped for a thousand bucks in San Diego. Was gone within hours. Or a Boyar-Schultz surface grinder in Torrance, right near me, for $350. Missing a guard but otherwise all there. Another one was a Harig 612 for 500 bucks. That one I could have gotten but.. I already have a surface grinder. Also for sale, from that same seller, were boxes and boxes of grinding wheels. This I thought worth considering. It was up in Van Nuys. After what seemed like 10 rounds of phone tag, the Craigslist gods smiled and I found myself walking into a make space just off the 16R runway by the Van Nuys airport. There were diamond wheels in there, lots of other types but I didn't really know. Lots of new wheels. I thought asking for the entire lot was best. I offered $100. Then $200. Then the seller conferenced with her boyfriend, off site. $250 was the reply. I could live with that.
After taking a casual inventory when I got home, I think I did quite well. It works out to about $1 per wheel. About a third are unused: new in boxes. The majority of the rest are used but still usable. I don't think I'll ever have to buy a grinding wheel again.
It was interesting to see how extensive the custom dressing was in most of the wheels. Very thin profiles, some were delicate rings only a millimeter thick.
The seller never set up the grinder or used the wheels, but the previous owner was a deceased machinist living in Ojai. He also had an EDM machine.
