I did just that, Dan. Looks like an inexpensive, but elegant, solution to a common problem. Thanks for the tip! larry sandiego16v I'm measuring the shaft at .75" which equates to 19mm. My favorite supply house www.mcmaster.com doesn't list a 19mm clamp but they do have PN 60485K68 which is what I'd try. Just do a search for "shaft clamp" and you select you own favorite clamp! Dan
