Kevin,
I have rebent Cinelli bars. Funny things can happen when a bar gets bent. The trick is to properly determine exactly where the bar needs to be bent and in which direction. The other hard part is holding the bar in order to make the proper bend. I don't remember what I did; but recently I rescued some old logo # 64 bars using my solidly pedestal mounted vice. From there I was able to get the angles and leverage I needed. Took about a half an hour before they were perfect.
