Crikey, you were right! A left hand thread! When I think of how I tortured that poor screw trying to get it off. The part was so loose by the end, it could practically swing, and all I had to do was turn it the other way - aaarrghh!
Oh well, I got off another piece: the bit that connects to the wheel on the underside and moves the shuttle from side to side. It's actually 2 pieces, joined like an elbow with ANOTHER stubborn screw, but I put the whole thing into EvapoRust to clean, and I'll figure out how to detach them later, if necessary.
Bonus: I've gotten the lower rod to turn! I can make the big wheel go round and round on the underside now, and hadn't even gotten around to removing the rust from the rod! Once again, it was good old sewing machine oil that did the trick.
I'm SO close to being able to pull the entire bed off the machine. It was only held on with a couple of small screws. If only I could a) remove the needle plate or b) raise the presser foot a few millimeters, I could slide the whole thing off. So far no luck, though. (That's probably a left-hand thread screw holding down the needle plate too, which has defeated all my attempts so far.)
