Did I break my lathe?

There is a MrPete222 video on YouTube on the subject of ways to remove a stuck chuck. I stupidly stuck mine a couple times and ended up making a tool using left hand threaded rod through the spindle as shown in the MrPete video. Basically that allows you to put a breaker bar on the back side to keep it from rotating. The left hand threads being key so you can pry the right way.

Since doing that a couple times I started getting a lot more careful about oil and clean threads :rolleyes:
 
I have the same lathe , the gears need to come off the shaft first.

I seem to remember that the cone pully has grub screws in it , mine were hidden under belt dust that had built up.

I came across this thread where someone refurbished the same Grayson lathe. There is a reply where someone had the same problem as me but intelligently asked first before taking a hammer to it. There is a little square hole in the gear and the gear is threaded. I'm not sure if that requires a special tool to hammer the gear around the thread? likely I've probably damaged other threads ..

I recommend a thread file. The other advice about files (farther up the thread) is good but it's a lot more aggressive and requires more experience and feel. Thread files are weird and seldom needed but this is the perfect application

Good point! Yes, a thread file in the right pitch is MUCH less risky!

Hm is this not too far gone for a thread file? I was wondering if I just filed all the bashed threads flat if it would still thread the end stop thing and the threaded gear on and off?

I can't find any information about threaded gears with little keyholes on them anywhere online. I tried putting a little screwdriver in that square hole on the gear earlier to try to tap it around the thread to take it off but got no movement. Is there some special key I put in there?

I would start with the tread file but you can might need to bring in the guns for this one.
 
I just wanted to tear it down to give it a thorough clean and oil. It's my first lathe and all the restoration videos I watched seem to take it down to the nuts and bolts
You can do that.

But, you’ll have to reset alignment, set clearances, etc.

If you take it apart make careful notes about shim placement and any alignment markings.

Without knowing there a problem I would be inclined to leave it together and start using it. That’s the only way you’ll really know the condition and if any work needs to be done.
