I'm fighting end float vs dial functionality. On the compound, the 3 hole plate is worn. It has a wear counterbore on the screw side and rough surface finish on the dial side. Dial needs to run on a sleeve so its not part of the gap setting stack up. I stoned and flipped the plate to temporarily deal with the wear counterbore. There is a non-orthogonality somewhere that tightens this area to non functional on 1/2 rotation unless end float is run very loose. I suspect the trimmed end of the Acme thread is not new geometry any more and needs some TLC. When I was cleaning the lathe some weeks ago I could not disassemble the cross slide dial area so I don't know the details of the internal problems there. I will need to try again.
