Actually Darren, Brass may be easier, we are headed into Bob's territory here but take a piece of brass rod grind the end flat tin it with soft solder, clean the ball up as best you can, I guess with all the wd40 and air that you've blown through it, it's pretty clean by now, paint some flux on the ball, hold the brass rod against the ball, with something that is heat resistant and then hold a propane torch on the rod as close to the soldered end as you can get without causing damage, after the solder melts it will start to remote heat the ball and hopefully enough heat will get across that the rod becomes soldered to the ball, and it can be pulled out, the big risk here is heat sinking into the main body.
Another idea if you have a pretty close idea of the ball diameter is to form turn a concave end on a rod and use some Cyano-acrylate glue to stick the rod to the ball, the risk being that you could accidentally glue the ball in place, but if you did that you could drill and tap a tiny hole in the ball now that it won't spin.
So there you go, just when you thought we were all out of ideas.

Whatever it is, do it today, Tomorrow may not be an option and regret outlasts fatigue.
