Stone Grinder Cnc

I am sure that grizzly sells a horijontal wet grinder.To keep the water out of the mechanism,simply have the vertical shaft for mounting the stone come up out of the bottom of the circular splash container maybe 1 on a sort of flange.Put a drain hole in the bottom of the splash tub,so that the water can never get deep enough to reach the top of the flange.You could also use sealed bearings.
