A lot has been done to this lathe. The difficulty I had when I first started making modifications was identifying where the parts were. That to say I had difficulty finding a great deal of available information. So here goes.
Many parts are available new from the atlas company.
The information is likely more easily found for someone whom is more familiar with Machinery tools of this variety.
The headstock, or spindle whatever it's called is 1 inch 10 TPI. The OE Pully requires a 2 L belt. 2L290.
I have since upgraded to a variable speed motor. I wanted to use the original belt size but the diameter changed with the addition of the DC motor. I ended up using the 2L260.
I learned in the process of sourcing 2L belts. The number designation denotes the diameter of the belt, 290 being a 29 inch felt, 260 is a 26in belt and so on.
The names are very specific for each individual piece on the lathe. The saddle for instance needed to be tensioned using a Gib, which involves using set screws. Those were very difficult to source for me.
Something that is worth mentioning, the Half Nut on the drive is 1/2 16 TPI. This was not readily available information and took some research to solve for.
I have more information to add to this which I will when I'm not using my telephone , but that is where the photos I have to add live at the moment. It's been a long time since I've made a post, I apologize that it is not welding related.
The lathe saddle was .003 out. this pully is loose. a new one will be made now that the issue is solved for.
