As I recall, no force at all. The gyro is completely broken from the 
ties of precession. And, the math says so. From what googling I've done, 
I can't find anything definitive. But I do love a mystery.

Yes. All I could find on ebay are the over priced pot metal toys. My boy 
has a fab shop and machine tools. Maybe the next time I visit...

Best, Dan.
