Andy, I think it's likely the cup was cross-threaded in there by a big machine and I may be looking at more drama if I ever get it out. New plan! The bike is near-new and most of it is higher quality stuff than this ridiculous bottom bracket (and the crappy crank I removed) so I stuffed more grease in there and put it back together. I have a square taper crank I can use, I'm going that way with it.
