I recently got a good deal on a new old stock Bison 10" independent 4 jaw.
Its the model with the FPJ logo instead of the actual Bison logo. In my
search to make sure I had actually gotten a chuck made by Bison I ran
across references to how fast you can spin a chuck. I'd never really
thought about it before.


The lathe I plan to use it on turns upto 2000 RPM. I have for short
periods spun the 10" import chucks that came with the machine at that
speed. Other than taking a little while to come up to speed I never
noticed any adverse issues. However! I'm certainly no expert on this
sort of thing.


How fast can I safely spin this big heavy Bison chuck? Is there a
reference where I can look it up? What about the cheaper 10" import 3 jaw
that came with the lathe or for that matter the cheaper 10" 4 jaw that
came with it?
