Lathe Cross Slide Problem

[EdK]

Got the .031" shim installed and it's still binding so I did the screw loosening process and at 1/4 turn the binding went away so now I need to make a .008" shim to add to the .031" shim. I think I'm hearing some scrapping of the nut on the trough. I'll know once I remove the nut and examine the bottom side for scratches. It appears I'm walking this fine line of keeping the nut from rubbing on the trough and getting the nut shimmed properly. I'm going to try adding the .008" shim and if that seems to do the trick and there is evidence of the nut scrapping on the trough, I'm tempted to remove the saddle and mill off .050" from the trough. I can't believe removing that amount would compromise the structural integrity of the saddle.
