Continuing work on this 1941 South Bend Lathe.

Continuing work on this 1941 South Bend Lathe. Spent some time taking apart the headstock. The white thing in the photo is a 3D printed thread protector. Not completely necessary, but I wanted to try making it. The headstock houses the drive pulleys as well as a back gear that slows the rotational speed of the spindle, as well as the spindle itself.

Splined Shaft Repair using Tig Brazing Wire


The splined shaft in the power feed clutch mechanism of my 1941 South Bend lathe has some wear and burrs on the ends of the splines. This is causing an issue with the effectiveness of the clutch. Since I have it apart, I’m going to go ahead and fix this now. I have no idea if this is the correct way to do this or not, never done anything like it before. But the risk is low. This shaft doesn’t spin at some crazy RPM, so I don’t see this causing any issues if I screw this up.

This is a splined shaft that is part of the power feed clutch on the 1941 South Bend lathe.

This is a splined shaft that is part of the power feed clutch on the 1941 South Bend lathe I am restoring. The splines have been rounded over at the top after 80 years of use. I’m thinking I might TIG braze some aluminum bronze on them and hand file them to shape. I’ve had good luck using it on cast steel, it should work here.⁠

1941 South Bend 13″ Lathe Restoration – Part 9 – Apron Disassembly


In this episode of the 1941 South Bend lathe restoration/refurbishment saga, I disassemble the apron. The apron has several gears and levers that are used to move the saddle and cross slide. A number of these parts are held together with taper pins that can only come out one way, unless the are busted in multiple pieces and no longer line up with the holes. The ride on the struggle bus was not always fun.
