Mike,
The collars can be ordered at McMaster Carr; 3/4 inch ID.
Shipping will cost more than the collars..... Charleston hooked me up with where to order when I needed them. Be sure to get that carbide set up from Paul.

I found them in a local hardware store! They had them in the drawers with all the nuts, bolts etc. Shaft collar 3/4" I.D......and yes don't forget the carbide cutter set from Paul!!
