I tried a decent-sized bearing puller. The Clymer manual recommends putting a penny on the nose of the crankshaft to prevent the bearing puller from damaging the threads. I ended up pushing the penny right into the nose.

Bye-bye crankshaft (it was damaged anyway).
I ended up biting the bullet and bought the
Airhead multi tool set from Cycleworks. Not cheap, but everything came apart and went back together smoooooooooothly.
