With it back in the lathe, did you try ejecting it normally, but leaving the pressure applied overnight? Or leave a wedge in there. Time and penetrating oil often work wonders. I've gotten results with a battery charger & soda too. Another thought to try - make a split bushing with a hole the same size as the spindle. Use one half as an anvil and the other half as a drift, pounding it with a hammer. You'd be momentarily changing the shape of the spindle, maybe enough to break the rust and let the oil work. I'd only try this just before it goes into the trash bin.
