Aw jeez, guys... don't go whacking the cotter! That's really not good for the BB at all. I have the Bike Smith cotter press myself and it's easy-peasy to use. Barring that, Sheldon Brown had a solution that worked in a pinch (check the site) and I've seen others cobble together a solution using a c-clamp and a socket. But heck, if you don't want to spend big money for the press (and that's as good a reason as any!), just take her down to the LBS. My local guys charged my neighbor five bucks.
