That's a sweet set up.I aquired this whetstone about three weeks ago and though I am just out of my bilateral inguinal surgery and recovering, I had to swap leads on the terminals to this Dunlap motor to produce the correct rotation of the stone.
The previous owner had the stone turning away from the tool, not toward.
I can't wait to get back some mobility and can get back to finding a great handle to hang my PLUMB
I have heard that leaving some of those natural sandstones in water can ruin them. Not sure if it's true or not but I don't leave mine in a bath just in case.
Maybe it's BS ?
