Newbie and questions about an old 109....

I guess just to be specific, just having a true spinning chuck would allow me to do alot of various small jobs that I'm already doing on the bench motor. Thats why I'm thinking of just getting a new spindle/bearings in there, getting the machine cleaned up and oiled, and then having something I can use right off the bat and continue to tweek/upgrade etc.

Hi @abracadabra,

It was a great learning machine for me. It was worn, but taught me what I needed to know to evaluate a lathe better next time.
I also learned how to (somewhat) work around the restrictions of small worn machines.
Looking back it was a great "stepping stone".

sheesh, $100 or so ? a regular guy will spend that much taking his wife or friend to dinner. . . . go for it.. .
 
If you get it; clean, lubricate, and check run out. What normally causes a bent spindle is a wreck while using the lathe.
If the spindle is straight there is no reason to buy a new one. If you need a spindle they are available with 3/4-16 thread. This is more common andit will be easier to find a chuck.
The spindle bushings wear very slow if lubricated so they are probably ok.
One miss understanding about run out: you can have a lot of run out and still turn a precision part. As long as the run out is consistent you can turn a true part.
A 3 jaw chuck will be sensitive to how you mount the part and as a practical matter will almost always have some run out, Again that does not mean that the part you turn will not be true and round. Don
