I bought this D/R11 which is in what looks like great shape. Lead screw looks original and still has brand new looking teeth in the center where it would see the most use. No damage at all on the ways or compound, no nicks on the chuck even. I’m the 3rd owner, first bought a few and started a machine shop back in the day, this one was hardly used they said, then it was sold to the guy/brother of the original owner who i bought it from and it sat in his garage for 25 years. He used it twice he said.
Anyways, looking at the gear there don’t seem to be any missing teeth, geometry looks original on the tooth profile it’s not like they are sharp pointed from a lot of sloppy use. The whiteness marks on the shaft under the spindle line right up as the manual says it should so it should have the factory backlash settings. I can rock the gear back and forth a lot, as in at least a few degrees and that’s got to be where the noise comes from... when it running without a cutting load it’s an inconsistent rattle is the best I can describe it as. Under a cutting load it sounds OK, but it’s far from a "normal" mechanical sound.
My question is. is this normal? I am somewhat new to this lathe and still learning a ton but not new to mechanical design. To me it sounds bad.
