Thanks. This info is very helpful. It sounds like if I get a sprocket
with a .375"
hub, I can probably bore it out. Or, I can get a clamp-type hub for
.75" and bore it
slightly to use the 20 mm handle hub. Hmm, only .452" thick, that is
too narrow
for a 1/2" belt. Maybe I need to use a 3/8" wide belt.

Well, if mine comes with the T nuts, then I don't have to worry about it.

Thanks much, it sure does help!
