Straightening a bumper
 

Anyone have any creative ways of straightening a bumper? It’s pretty thick steel, original bumper on my 63.
Hoping to do it cold; do not have an oxy-acetylene torch.

Find something that has the radius of the curve you are trying to fix, or make a “buck” of the lip/radius then try a press, that and a lot of patience

If you could find another damaged bumper you could cut the damaged portion out and weld in the matching piece.

I just smooshed mine with a back hoe bucket while it was leaning against a big pile of rocks to straighten it. My truck doesn’t go to car shows.

Mine isn’t a show truck either. I don’t have a back hoe or a press.

A large adjustable wrench works pretty good for straightening out bends that are near the edge like that. Open the jaws just wide enough to fit over the edge and use it to bend the metal back into shape. Don't try to bend it back straight in one shot since that tends to cause the wrench jaws to introduce extra bends/ripples into the metal. Instead, just bend it back a small amount, working you way back & forth across the damaged area, until it's straight.

Another method that works pretty good is to use a large heavy duty C-clamp along with a chunk of thick steel ... something considerably thicker than the bumper (or whatever you're trying to straighten) so it doesn't bend instead.

It moves pretty well with a three or four pound hammer.
