Hey guys -
I'm working on a Leblond 15" Regal lathe and want to remove the 90thou backlash in the cross slide leadscrew. So I set out to replace the screw, however I'm running into a bit of a wall and wanted to get advice here.
I ordered this: McMaster-Carr to replace the screw part and a 2.5" drop of brass to make a new nut.
The issue that I'm running into is I can't get the spline off the old screw. I knocked out the pin, but the spline won't budge. Any advice?
Thinking maybe to cut the old screw right past where the pin sat, bore out a bit of a hole, turn down the new screw for an interference fit, then just drive a pin to hold it together. I'm just worried about concentricity, but not sure how much it really matters in this application if I'm off by even 5 thou.
As an aside, anyone on here want to make the nut for me? I can't seem to find my 4 jaw chuck.
