I am a retired carpenter and fairly new to machine work, (about 5 years). I have a classing 5914 lathe that I absolutely love and would never part with, but have got into buying small lathes, cleaning/repairing them, then selling them for a small profit to support my machining habit. The problem I have is I would love to keep one as a back up lathe, but can't decide which one to keep. I currently have a 1945 9" south bend model A bench top, a 1948 10" Logan/Montgomery wards bench top, and a 1966 12"atlas/craftsman commercial cabinet model. Easy lathe has normal wear, and each with it's own advantages and disadvantages. They all have QCGBs. You would think the bigger 12" atlas/craftsman would be a no brainier, but the flat ways and "zymak" gears has me worried. All suggestions would be appreciated! Thanks, Jim.
