I purchased my grandpa’s Birmingham lathe and knee mill a few months ago from my dad and just recently got them placed in my shop. My grandpa had wired them for 110 and when I fired them up they are both grossly under powered. My grandpa passed away over 10 years ago so I have to backtrack whatever he did to the wiring to bring it all back to 220. I was able to figure out the mill and it is now firing on all cylinders and is working great! The lathe on the other hand, I am beating my head against a wall. I can trace it all out and eventually figure it all out but I thought I would post it up here to see if anyone has a wiring diagram, or photos of their wiring box and motor so I can figure out what is missing a little easier and quicker. It is the older Taiwan made Birmingham 14x40 with a single phase motor. I tried to attach photos but it keeps coming up with file size being too large. I’ll work on that issue later. Any help would be greatly appreciated! Thanks in advance!
