I bought a bunch of tool grinders a while back and this was one of them. Does anyone know anything about these? I've searched the internet and haven't come up with much. It was made by Union Twist Drill Co. I've used some of their drills before but I didn't know they made machine tools. It looks like it ought to be able to grind a radius on an end mill but I'm not a tool grinder so what do I know. Anyway it's a pretty cool old machine and other than the crappy paint job, it's in pretty good shape and I'd like to learn how to use it. I've got thousands of end mills I can practice on.:D
