I bought a neat grinder at a flea market. Its a Sani-Grinder made for shaping, grinding and polishing orthotic appliances. 1/4 hp 3450 or 1725 rpm and runs in only one direction. Its American made and seems to be built well and runs smoother than my Chinese grinder. I wanted to make a tool grinder out of it but I'm not sure I can. It has a 3" drum sander on one side that is attached with what looks like a #1MT and a squirrel fan on the other side attached on a 1/2 round shaft with a set screw and no flat.
Any ideas on how I could make this into a tool grinder? Should I leave it and use it as is or try to sell it outright as they apparently are very expensive new. I will post a few pics also.
thanks in advance for any input
