>>2031568ok, go nuts, I guess.
an adjustable wrench is the tried and true tool, the handle allows for good leverage and ease of moving it in tiny increments.
the last time I did it, I left the derailleur on and used a jorgensen clamp: one jaw on the inner hanger surface, around the whole derailleur mount, and the other jaw on the mounting bolt. the handles gave pretty good leverage but it was really easy to see how it needed to be moved and line it up with the derailleur still on it. this was a welded steel hanger, though. I still think you should be able to bend yours, though, but I just can't speak from experience.
