So, a few years back, I managed to find myself a lathe. Schaublin 102 precision toolmaker's lathe, sold as "not working" and with a lever actuated cross slide. Was actually working fine, but required a 220V three phase supply, was also supplied with a whole bunch of other stuff, milling machine divi...

There's loads of plans in the pinned topic at the top of this...

I'd have done it with gas, but I don't have access to oxy-acet' any ...

Excellent!
