Maybe I'm looking at this wrong.
The jaws are true. Not enough run out for the work I do.
Problem I'm having is the outer part of the jaw will not hold thin material.
I am trying to hold a thin tubing, with a mandrel for support.
Because the jaws don't hold all the way out, the tubing sometimes spins in the chuck.
This is why I think the jaws are not parallel when clamping towards the outside.
Does this make sense????
It's called bellmouth, and it's common enough that it has a name. The jaws/scroll have been tweaked/worn from clamping parts at the outer end. It may not be apparent unless the jaws are loaded (under pressure).
