Viel-- variable speed or slower speed?

You know, belts are somewhat different than a stone. I’m sure that many will disagree, but sharpening into a belt gives me the creeps. If the belt grabs the edge, it could cause regrets, or even possibly epidermal leakage.

Of course you would never, ever, use a leather, felt or other soft belt into the edge.

So, I think your reversible motor is a good thing.
