Shrinking panels?

[Rhett]

I floped my zuk on the weekend and dinted the side of the bonnet. When panel beated back to shape is still has a wobble in it as it has streached the steel. Any one know how to reverse this??

um im not sure if this helps at all

but maybe you could use a wooden mallet and a dolley
(was taught this at tafe malet for shrinking and hammer for stretching)


maybe you could maybe hit it back in so it kinda has a slight bend inwards and smooth it out with bog

The method I have used before is with an oxy and a water soaked sponge.
Heat up the affected area one small (50c coin size) spot at a time until red hot, then hit it with the sponge. As it cools quickly it should shrink.

If you don't have an oxy handy, you can just make a small inward "V" in the panel - with a hammer and dolly, then bog over it.

The shrinking dollys I've seen have had a surface a bit like a meat tenderiser. Just go easy and it's fairly straight forward.

roll it on the other side

as isuzurover mentioned, heat the "stretched" area's and cool them down quickly.

the metal will essentially remember where it used to be (someone else can go into the long winded explanation for me)
