It's a hybrid of aluminum hub with nylon sleeve that I pressed onto it. It's not a solid wheel, as I think the aluminum part started out an ashtray or something similar. Total weight is about a pound or so. There's a very small crown on it, pretty much the same as a MT drive hub. Works well.

Looks good and I bet a whole lot cheaper than the MT. I still use my MT almost every weekend for something or other, so I can't complain about the price. Belt grinders are the way to go!

exmaxima1 - thanks for linking me here to your build thread!

I assume the black handwheel on the right locks the round shaft from spinning as well as fix the shaft fore/aft after the spring has taken the slack out of the belt?

How are you rotating the assembly up and down - looks like a countersunk set screw at the grinder/arbor area.

I like the abrasive cutoff wheel on the left. I can see that as quite handy. Clever.

Yes, that thumbscrew does lock the the tensioner. As far as the rotating assembly, that's not a setscrew. The assembly has a split bore, and that is a bolt that pinches it to the motor end bell.

Thank you.

Your description of the split bore at the end bell was exactly what I was trying to describe.
