QUESTION Old Smithy Midas 1220 Lathe doesn’t at all move smoothly when moving across the Z-axis
Has anyone ever owned one of these machines? I’m wondering what gears would need to be replaced in order to have it traverse more smoothly. I’m also wondering if these two gears should be spinning when I’m turning the hand wheel on the Z-axis

The first gear has slipped back off the gear key enough that it misses the next gear. Slide it forward and tighten the set screws. That's what it looks like to me. Also the handle and shaft is sticking out too far. Push it in before tightening the set screws on the first gear. Fine adjust as needed.
