Long retired tv engineer, with 3 other CNC machines in my stable already but toys are toys. First big (to me) lathe, a 1952 Sheldon 11" by about 42".

Buckets of backlash Between that, and difficulties with the clutch in the apron, I am inclined to just rebuild the crossfeed for a small rear driven ball screw, and one in the 1300mm, 20 or 25mm diameter for the carriage, doing away...
