I have an Airstream 345 motorhome that got bumped in the rear.
The bumper got pushed in about 3 inches and I want push it back
to it's original shape. They are extruded aluminum about .2 inches
thick. They are in the shape of a channel. I have a 55 ton arbor
I have been thinking about the best way to do this. I think that
I will make some wooden blocks that conform to the original
shape and use them with the press.
I have seen some amazing results in straightening alloy wheels
but they heat them. Should I heat the bumper? What temperature?
This is what it looks like next to my front bumper. The black mark
near the bend is just a reflection and not really there.
This shows the extent of the bend.
