Most of the nuts came out with minimal force, but the last one just spins in place. I tried rubber gloves, painter's tape, and duct tape to get a better grip. I'd rather not cut a slot in the domed nut if there's another good strategy.
The rest of the restoration underway:
Wood glue isn't going to hold on metal at all.
Anti-seize to stop spinning? What? No. Anti seize is shit you put on threads so that when you come back years later, they still move.
Long acting lubricant.
And drilling out a bolt that's already spinning isn't going to be a fun time
