It doesn't necessarily mean its toast, it depends how bad it is. If it isn't too bad it will still clamp softer materials fine but could struggle with hard materials. (the jaws wont bite into hard

I bought an aftermarket 4-jaw chuck, but rarely use it.? When I do, its for different reasons, occasionally to get something more precisely centered, but even then it is more reliable to turn up a

I'll give that a try, is there anything do if the jaws are bell mouthed or is it toast at that point ? Are the soba 4 jaw chucks a better than the three or are they useless ? Any suggestions on a 4

I have had a number of 3-jaw chucks pass through my hands. I can offer the following observations. The earlier ones did not have a cupped washer in the back. The scroll ring on these usually spins

Hi there I've been trying to centre just round peices of steel and aluminium but just having too much luck, I also don't know anything much about machining or this lathe, so I have no idea what I'm
