As much as I thought the idea was ******** I watched how the old wrenches at my shop "adjusted" bent forks. I thought it was damaging for sure but apparantly you can do it once if its minor and get away with it.
Turn the wheel around in the frame and run it into a wall. IT sounds blunt and harsh but it workes. IF its a cheap, old brazed fork you may wanna just buy a new one for $15 though. Save your teeth.
