Vicmarc chuck not fitting on general lathe
I am using a vicmarc chuck at the moment for work, it came off the
general at work, and has fit on my general before, now it is refusing to engage and go all the way on, so I can't work till I fix it, any sugestions they are both 1x8's and it should fit, the threads are all clean. -- All they do is slap some lipstick on and try to pretend it's not a pig.

Might also check for an unthreaded portion on your shaft right up near the bearing. For reasons unknown, my 3000 has some. Believe a couple others do as well. Workaround is a precision washer or bushing to take up the slack. |

Reyd,
I have a couple of Vicmarcs, and have run into this problem a couple of times. It has always been chips and/or other crap on the threads, either on the head stock, or the chuck. Sometimes I can't see any junk, but blowing out with the air hose, and/or using a wire brush usually do the trick. If the chuck starts on ok and bogs down before it is tight. then there is something on the threads, even if you can't see it robo hippy |

Are you sure a drive center isn't in the taper? (I have a small drive that will fit inside my Vicmarc threads but I can seat the chuck all the way on anyway - maybe if you have one in the taper it's stopping the chuck from seating.) |
