Good to hear, all of it. I'd maybe flat the shaft, but those setscrews aren't either big enough, nor long enough to not work loose, junking the holes in the pulley. If I flat or drill the stub, I'll replace the screws with much longer socket head cap screws. That is a thought, and may outlast me... And its at least a days fooling with TLM to do it. I think I'm convinced. ;-) Again, Thank you very much MC Cason. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
