Grinder Workhead Rotation Direction?

If I'm looking at the T and C grinder from the right hand end, the grinding wheel rotates counterclockwise. I never observed the workhead motor operating before I brought it home from Peter Fou's and I have subsequently dismantled and reassembled the motor. My assumption ( ? ) is that the motor would rotate in a clockwise direction. Seems straightforward BUT I recall a discussion a while back about my Dumore tool post grinder and the trouble I was having achieving an acceptable finish. A suggestion was made to reverse the lathe spindle rotation.



So my question is "when cylindrical grinding, in what direction does the workpiece rotate? "
