Are items #110 the bearings ?
I bought the lathe new twelve years ago and have only threaded with it a few times, the high side threads have always been poor quality but the low side have always worked fine. Cheap Chinese labor, you get what you pay for.WoW !! How many of these barrel threads have you cut on this lathe to have so wallowed out that key slot ?
Thanks, I've checked all that and snugged everything up, I have .010 backlash on the leadscrew. I also opened up the headstock and inspected every gear in the train, I ran about 50 passes and had no malfunction in aluminum. Replacing the gear made it thread "better", if it does it again threading in steel I will blame it on tool springing or operator error. thanks again for your help.I reread your first post. If your tool dug in, then your problems most likely are in your carriage. Do you have a lot of backlash in your cross or compound leadscrews?
Your cut of 0.001" shouldn't have caused any issues. My guess, is that your backlash isn't being taken up properly and the work piece is pulling in the rest of the backlash into the cut.
