The workpiece slides in (or out, depending on which way I'm cutting) on my
Sherline 3.5 x 17 with the 3-jaw chuck. It just started this and I've had it
four years or so. Plus my much older Clausing 12 x 24 never does this. I've
cleaned the chuck and there is no oil on the jaw faces. I'm very puzzled.
Even taking just 0.005 cuts the piece just wont stay still. This project
involves cutting a ball, so a tailstock & center isn't the answer.

Sure would appreciate any insight. Thanks.

Are you sure the workpiece isn't so small that the jaws are meeting each other
before gripping the part fully?

I'm not at all sure why women like men. We're argumentative, childish,
unsociable and extremely unappealing naked. I'm quite grateful they do though.
