I've actually got another grinder, either identical to the one I got today, or at least very similar. It's virtually unused. I rescued it from the scrappers who hauled off an AMMCO brake lathe that was replaced by the school system where I worked when they "upgraded" my shop equipment. I wish there would have been a way to salvage the whole machine, but it would have required me to virtually steal it. Not a good career move!
