Balancing chucks?

(1/2) > >>

28ten:
Whilst testing the mini lathe I noticed a lot of vibration being caused by the chuck, this can't do much for the bearings or indeed accuracy.
Does anybody have any recomendations for curing the problem?

sbwhart:
Chuck are well balanced when you get them, its probably the mounting that at fault, can you waggle it, does it pull down square on the mounting plate, have you got the jaws in correct, are the bearing lose ?.

Chuck up a length of sturdy bar get hold of the end and try moving it up and down back to front, it shouldn't have much movement if at all.

Hope this helps

28ten:
The chuck is firmly mounted and the jaws are correct. Maybe I should try it tonight without jaws? See if they are the cause.

jim:
have you tried it with out any gears being driven? sounds more like a bearing on its way out??

28ten:
The bearings are fine, it's definatly the chuck. I hope it's something obvious I have missed  :D
