| 4 jaw chuck |

| modelman1938:
I have read many times in modelmaking magazines, when doing repetative jobs in a 4 jaw chuck to loosen only 2 jaws and note which ones these are. Place the next part in the chuck and tighten only these 2 jaws and it will run concentric. I have been following this method for over forty years and so far it has`nt worked out once and I have had to clock it in every time, I suppose it must work for some people or they would not recomend it. has anybody had any luck?.

Hi John, Thanks for the video. Much better for us beginners seeing someone do it rather than reading it in a book (which I do as well). The clip at the end just tops it off. :thumbup: Keep 'em coming. I'm learning a new language as well. Gary |

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.
