slamming the piece back in the 4 jaw never works. opening up just 2 jaws and reversing never works. the closest you can get is by using collets and even then its touchy.
i always plan for no re-set ups, if I have too clocking in always has to be done, and then thats done with a collet holder for the job if i am turning or milling or if too large i have a spigot on the mill that has my thread for the chuck, again thats 1 or so thou out.
