Re: Jeff's mill drill Timing pulley milling cutter

Well i would order belts from local bearing house, do not know of any
discount house.

I would really only want to use PowerGrip GT2. I looked around for a
few hours earlier for specs and could only find a sketch of various
belt shapes for comparison with no dimensions.

I think I found the patent here, but no dimensions.

Any ideas were to find them…
