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.
