Default Lathe chuck problem

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.
