Boring ID jaws

[M Code]

I want to clamp 6.5" on ID. So, to turn the jaws do I change the chuck clamp to ID and I turn the jaws till 6.5" ??

is this the way?

Yes, get a bigger ring for the od of the jaws to press against. Then turn jaws to size you want.

You want to reverse the clamping if that is what you are asking and then cut just a little over size with a positive taper toward the back. How deep are you going?

the size that I turn = the size of workpiece ID

the chuck is clamped in reverse?

You have to bore the jaws bigger than the work piece on a part that size I would go +.005/+.010. I would also bore at a positive taper smaller in the front bigger in the back.
