Here's my lazy way 
In the 3 jaw chuck turn all the od's and the thread - using a center support.
Hack it off about 1/4" longer turn it around and place it back in the 3 jaw chuck. Use some brass shim as to not mark the od. "Clock" it, if I can get it to be less than a thou off I go. Sometimes by rotating it in the chuck it can help.
Now if it is not cooperating I swear at it, go and talk to the dog have a cup of tea and a fag. On returning I swear a bit more at it and put the 4 jaw chuck on.
