What's This?

Came with my lathe. Not sure what it is, what it does.

(this pic is not of the actual one, but just like it).

I agree with previous posts, a jackshaft for grinding or buffing, the threads should be opposed on the ends.

I agree with the above, but just to be clear, it's not part of your lathe.

I agree. I've seen those mostly sold as a "build your own buffer/grinder" part. With the bearing blocks so clost to the mounting ends, it looks like it would be better for a grinder setup.

Those saying jackshaft for grinding wheel or buffing are correct. I doubt it came with your lathe originally but having it is not a bad thing, now you need a 1750 rpm 1/2-1 hp motor and your in business.

Yes, is jackshaft for grinding, buffing etc.
However, it might also be used with carefully sized pulleys & belts to change lathe speeds.
I've seen it done with drill presses.
All kinds of potential complications, some bad.... But could be done.
