I bought a 6" unknown 3-jaw chuck to put on my rotary table, $23.00 on fleabay, stated that it needed cleaned up. I disassembled and cleaned it up. It turned out to be a Union chuck. It has " class S " stamped on it. Anyone know what it means ?
It looks to me to the thru-hole has been bored out. there are 3 holes in the back that have been bored into and 3 holes thru the front. I know the 3 larger holes in the back are for a backplate.
What are the bolt holes in the back and front for ?? dust cover ??
Any ideas are welcome !
