Do you have a lathe? If so, I would use that..... If not I would suggest boring some soft jaws to the finish od. Use a small jaw spacer so you can get as much "even" clamping force to the od of the part as possible. Basically make a split collet out of your soft jaws.... Releave the jaws for the boring and taping ops and try to clamp the part as lightly as possible. Just not to light... Good luck
