when I bought my lathe this little chuck was tossed in I never played with it too much until the other day when I got the idea it might be great for small pieces and as I only have a 4 jaw on the lathe this would be great as I could take pieces out to measure and not have to redial the work steady... well I took off the 4jaw and popped this thing in... its mt3.. well I put the dial on it and it was out .050" wow... so I didn't end up using it... looks like its seen some use and abuse is there any fixing these or are they any good to start with?
