My first lathe!! Old South Bend.

[Manual Mac]

this repair was done on my SB9 probably 60-80 yrs ago.
Done with the method matthewmuppet2 explained, although it may have been done with 6-32 screws.
This repair is still working fine, I cut threads often using the back gears.
Cheers

Your lathe looks like an old Workshop 9" model C lathe. I'm not sure that this model lathe is covered in the Illion book on ebay (too early). Also, these early lathes only used one type of oil (Type "C"). This one also didn't use the grease. I'm also not sure about the wicking system in this one. I believe that this lathe used a flow-thru lubrication system entirely (no sumps). This one used felts to retain the oil and slowly dribble it out where needed, but had to be loaded from the top.

Type C oil is a light hydraulic oil, modern ISO 32.

SLK001,
I just noticed your post as a model C. I bow to your expertise.
I assumed it was the B as in the attachment.

These lathes were only made for a couple of years. They were replaced by the later 9" series that is so common now. I used to own an old Model C Workshop. My grandfather was the original owner. I sold it after I picked up a Heavy 10. Nostalgia can only go so far!

well the world's your lobster if you have the ability to do MIG or TIG brazing. That's pretty far out of my wheel house so I'll defer to others, but the screws will certainly serve as a good anchor if there are any worries about how well the braze can be built up on its own.

These posts are getting me to think that maybe I will just repair mine with the screw method, and if I mess up, I can just do the add the gear method I described earlier.

ADM, there is a cone pulley available on ebay right now, just listed yesterday. I am not experienced enough to advise on whether or not it is a good deal or if it will fit your lathe.

Thanks! I'll check it.

Ended up taking a crack at doing the gear repair myself and I think it will work. Drilled and tapped for some 6/32 screws then TIG brazed silicone bronze around them. Shaped to finish.
