Re: Cold bending 1 piece cranks?
Typically, if you go slow and take your time the metal will bend without breaking. Cranks are not made of extremely hard steel that would be prone to failure with careful bending. I've seen cranks on bikes that were run over by cars and they were bent way more than you'll need and they didn't break. I would suggest to concentrate the bending force so that you aren't compromising the bearings. Go for it and please share your idea/photos for a bender that others might find interesting.
