The lathe is a 1-1/2 yr old Delta 46-460. When we try to use it with a PSI Mandrel Saver, there's some pretty bad noises coming from the headstock. The noise gets louder and louder as I tighten the tailstock up to increase the clamping force on the bushings and pen blank. By the time there's enough force to tightly hold the pen blank, the noise sounds pretty bad. If I lighten the clamping force by backing off the tailstock, the noise goes away. But the blank is no longer clamped tight enough to turn it with a gouge or chisel.
Has anyone else had this sort of trouble using the PSI Mandrel Saver on their lathe? What can I do about it?
I think that maybe the PSI Mandrel Saver requires a lot of tailstock force to adequately hold a pen blank.. And that this force is transferred as a large side thrust to the bearings in my headstock causing my bearings to make noise. Anyway, I'm afraid that the headstock bearings might get ruined if I use the PSI Mandrel Saver.
I'd sure appreciate any help or ideas anyone has to offer. Thanks.. Larry
