Joe and Grant,
I have in the past resurrected a worn out motor pulley. I moved the pulley over along it's shaft until it's edge would make contact with the handwheel. I then ran the motor at a fast clip and 'gouged' a deep groove in the old pulley's middle with a rough file. The depth of this 'gouge' was the same as the inside diameter of a bobbinwinder tire or o-ring. Slip the tire or o-ring over the pulley and realign it to the handwheel. Works perfectly. Clear as mud?????
