I glued a shift knob on my old 510, with a metal looking compound , check to see if it has been glued by PO.....

That may be what happened, there appears to be some sort of resin or compound in the center of the knob when viewed from the top that could be glue, as the cap is missing. I've assumed its just a filler, but it could possibly be binding up. Its just strange that it'll move just an 1/8th turn every once in a while, I couldn't think of any sort of glue or locking mechanism that would allow it to turn a small amount once a day, haha. I'll also try heating it up when I get the change.

I think that the resin or compound you are seeing is actually a sleeve made of some kind of plastic material that is threaded for the shift lever. It should be a very light beige or amber color. This sleeve is actually glued into the hole in the center of the wooden shift knob. As you suggested, if there is no locking nut under the knob, you may be able to slowly apply some heat from the top where the shift button would be to slightly soften this liner material to release the shift lever.

Just a thought

I had that exact though, I'll give it a shot.

If it's not stock, one other (unlikely) possibility is that it has a set screw threaded into the bottom to lock the knob in place. If there's no retainer of any sort and it's a plastic insert as suggested above, I'm kinda surprised that the threads in the plastic don't just give way and strip out.

That's what mine did and I ended up making a threaded brass insert and glued it in place to replace the original plastic one.

Looks nice. And yeah, I wonder too about the stripping. The threads on the stick itself appear to be in good shape There must be some lock-tight on this thing. Maybe I need to add a belt wrench to the toolbox, not that my makeshift ones have really helped.

Carefully apply heat with a heat gun and see if it loosens up. Don't melt anything.

Heat up the Shift lever, not the Knob!

I got it off, just by doing it a little a day at a time. Took about a week altogether. When I got it off, it looks like its not threaded at all - Looks like that stuff was just glue, and I was making the threads as I turned. Haha. What a pain.. I've started sanding, and it looks better already. Still waiting for my gear map to arrive from Canada from Rob, then I'll rethread it.

Thanks for the suggestions guys!

Yup. I bet all your threads stripped out and so your previous owner gooped it up with epoxy and then shoved it onto the shaft to set-up.

Out of curiosity, how are you going to rethread it?

And more evidence to the file as to why this kind of repair is referred to as an IPO repair.

I was gonna see if I couldn't do something like Cap'n Obvious did, with a threaded insert of some kind.

Indeed, haha

I'll make you an insert. Send me a PM.
