Ferd/289 Posted February 2, 2007 Share Posted February 2, 2007 love the progress, and getting a better understanding of how a lathe is used. Thanks for the pics, keep 'em coming Ferd Quote Link to comment Share on other sites More sharing options...
CRAVED Posted February 6, 2007 Share Posted February 6, 2007 i've just got a Lathe myself (borrowed from a mate who is moving for a few months) and i was trying to find some info on how to centre the 3 jaw chuck a little better as it seems to not be centering very well. i've read through the links posted and dont think the mods in http://warhammer.mcc.virginia.edu/ty/7x10/vault/Lathes/7x10-7x12-Projects/SetTruBackplate/ are really something i wanna do with a borrowed Lathe any tips would be great Quote Link to comment Share on other sites More sharing options...
datsunlover Posted February 6, 2007 Share Posted February 6, 2007 Generaly, 3 jaws simply do not run perfectly concentric, just the nature of the beast. Some can get pretty close, granted, but if you REALLY need to be precise, then a 4 jaw is what you need. Although a 4 jaw requires more skill/know how to set up a piece properly, it is the best way to run the piece perfectly true. That is an interesting link, but I would still go for a 4 jaw myself.. I don't believe that his 3 jaw (modified as it is) is going to be MORE acurate than a 4 jaw.. it just takes a lot of effort to get the 4 jaws running prefect (read; skill and patience!).

CRAVED Posted February 7, 2007 Share Posted February 7, 2007 Pretty sure there might be a 4 jaw chuck with the lathe, will dig through the boxes and have a look for it, then try it all again thanks for the insight Quote Link to comment Share on other sites More sharing options...
lbhsbZ Posted February 8, 2007 Share Posted February 8, 2007 How to center a 3 jaw: If the chuck itself is not acurate, clamp something in it to secure the jaws, and cut them true with either a boring bar (inside jaws) or tool bit (outside jaws). Generally, my chinese 3" 3 jaw clamps work perfectly, with no radial runout. I also have a chinese bandsaw that couldn't cut straight if my life depended on it, so if I chuck up something that I've cut on the bandsaw and measure runout an inch or so away from the chuck, its all over the place. Just get a dial indicator and small mallet and tap tap tap until you can measure runout in 2 places on your piece of stock and come up with 0. I through a hub on my 7x12 the other night to try to make it fit in a cobra rotor, and measured runout on the hub face as well as the radial runout. It took all of 2 minutes to get everything to 0. 4 jaw chucks are a pain in the ass. Maybe I'm just slow, but I usually spend at least 10 minutes or so trying to get something straight in a 4 jaw. I only use it for cutting odd shaped stock or offset holes. The 3 jaw gets used for everything else. Quote Link to comment Share on other sites More sharing options...
