This is not something I really plan in doing so this is merely an exercise.
Suppose you have a chuck with jaws that are slightly out of whack. You get the chuck body running true and a rod TIR is good 1" out from the jaws.
Then you measure 10" from the jaws and the TIR is way out.
What I'm wondering is if anyone has ever trued up the back of the chuck based off the jaws. Look at the following pictures.
Mount a bar in a chuck or collet. Turn it to true it up perfectly with a live center. Then slide the chuck over the bar and tighten the jaws.
I would thing that this would align the jaws with the bar. Then any difference in square should show up in the back of the vise.
My question would be how do you think this would work to square up chuck by taking a skim pass on the back of the chuck. (of course removing the pins first)
Would it stay square chucking different size bars?
What are your thoughts?
