Bought this Dumore grinder in a lot. not sure what it is or does besides grinding. There is a large pulley? on the back of the grinder as well. Has an old style tool post that folds down. Came in a built to fit Dumore box with tooling. There is a keyed chuck that slides the motor up and down the ways to move the grinder in and out. There's also a fitted stationary base to mount the unit into held in place with thumb screws. There are four holes in the side of the motor looks to be a way to use it in a different application. Its in great shape, spools up nicely doesn't look like it was ever used. Any insight would be appreciated.
