So a few months back I purchased an atlas 4804, which as I understand is a Clausing lathe. At 12" there is probably .010 inch or more runout. Something that is very visible, might be more then I'm claiming. This is with the 3 jaw chuck. I have also a 4 ja2 and a face plate but have been unable to get the 3 jaw off. So is the small chuck the problem or do I have a bent spindle?
I have checked that the run out is not the stock but rather the chuck by rotating the stock. All bearings feel tight with no play. Run out is less at chuck then 12" or more out by a long shot.
I've tried using hex stock with a cheap air impact wrench to get the chuck off so I could try the drill chuck or 4 jaw but that hasn't worked as I've been unable to break the chuck loose.
I'm guessing somebody crashed this at some point however I can find no other signs of damage. Maybe(I hope) this is just a really crappy chuck.
