This idea has such shade-tree elegance, and yet I don't think I have 
ever heard of someone saying it actually *worked* for them.

Yup, the nasty tools came last as the bearing slowly disintegrated.

Ideally, you get a few hooks of some sort behind it (a few, so you are 
pulling evenly) and give them a steady tug or sharp rap or two and pull 
it out straight and intact.  I'm assuming that the "tool" for the job 
allows you to do this.

In fact, I am imagining how it would be put together right now... three 
hardened little hooks mounted with pivots to a central core piece, that 
is threaded down its center.  When a bolt is run through to push against 
the inside end of the crank, it also prevents the hooks from letting go. 
  Actually, duh, it is the bolt that "activates" the hooks by spreading 
them out.  Patent pending, haha.
