How are you verifying TIR from the Threaded part to the .562 Diameter?

If everything is on dial in the Machine, the TS shouldn't have anything to do with runout. Unless of course a person is using the same center hole to do final inspection. That's why I asked....

.562 dia shaft over 4." long with a .194 dia thrd relief at .6 long with a .250 -28 ext thrd at the end .300 long. I turn it all together with the tail stk ingaged the tail stk is running concentric to my chuck within .004 (not bad) but after i turn the part, and all is running concentric with the tail stk ingaged, when i retract it an remove the part from the machine the .194 dia springs enough that i have as much as .002 run out at the end (the thrd pd)
i have a .001 potion call out thrd to .562 dia. (which works out to .0005) would that head stk being off from the tail stk cause the problem i cant consistently hold true postion for the run out. (no matl condion call out)
