What's wrong with my lathe motor

Something to keep in mind for next time.  I found this handy image here:

That might not fit into the can that the capacitor goes into on most split phase motors. However, I have done that to solve the problem of not being able to obtain the long obsolete "sardine can" capacitors in vintage Craftsman with the capacitor in the base. Excellent old motors that run very quiet. Definitely worth repairing. Put shrink tube over the crumbly wiring. The bearings they used were so good you just repack them and good to go another 50yrs. You might have to add a pig tail to allow hookup to a drum switch for reversing but well worth the effort. I put one on one of my South Bend lathes and it runs sooo quiet. Also adjusted the end gears for the quietest operation. Really nice.

When my motor goes out, I'll be doing the VFD thing or perhaps BLDC route.

Either way, I want to automate the feed and crossfeed.

I managed to source this capacitor locally, 270μF instead of the original 300μF but it seems to have done the trick





The capacitor came with a resistor between the terminals, which from what I've read is to bleed off residual voltage from the capacitor when disconnected, but I removed it as the original didn't have one.

The tolerance for new electrolytic capacitors is usually +_ 10% (yours is +20  _ 0) so you are ok but it's so easy to obtain a 300 I don't know why you would sub.
Not going to hurt anything you're only spinning a chuck on start up. Only going to be on the start windings for  a split second.
Glad you got your lathe going again!

If you ever replace those twin belts make sure to get a matched set. +++
