[AT] Bending a wheel? [OT]

[Louis R Godena]

I know that popular lore decrees that once a wheel is bent, it cannot be 
straightened, but is that really true.   I have a spoked wheel on a hay rake 
that is badly bent (I did it driving too close to an apple tree).   Has 
anyone ever seen one straightened successfully?   And who does that sort of 
thing (fix it, I mean)?

Any info, even anecdotal, would be great:-)
