How should i go about fixing this? I want to straiten my rim out soon and this dent makes it had to find where the rim needs to be adjusted. I was thinking od using two blocks of wood and a big C clamp to try to squeeze it together but i wanted to know if there is a better way to do it?

I have the same problem, just not as bad, I'm also looking for suggestions

My rims are practically square. My advice.. Keep riding, replace the rim when you can afford to. I only feel it shake when I'm wide open in fifth, which isn't very often.
