[oletrucks] woodruff key tricks?

["McNulty, Bob" <BMcNulty@csuchico.edu>]

Anybody have any suggestions for removing a stubborn woodruff key from a
generator shaft.  I've tried the screw driver hammer trick, soaked it in
various penetrating oils, even heated the shaft mildly in combination
with the screw driver tapping on the end trick.  All to no avail.  

Thanks,
Bob in Chico
