Re: Set screw holes to act as keyways
tighten the set screw down hard where you want the pulley remove it and look for the witness mark. You can then drill a divot of just file a flat to increase the locking power. Depending on the shaft and set screw sizes drilling all the way through could compromise shaft strength.
