Anyone ever use a pinch roller on steel

What do they look like and what do the do??

Usually used for softer material, etc..etc to form or increase
strength of material.
See if you can open this image. Looks like a standard rolling
press....
What are you making now?

I want to open the wheel wells of my door slammer and was thinking about doing it that way.

Trying to get this effect.

Most of them I have seen vary in size from about like a shop shear up to very large production equipment.
Is this for the outer fenderwells on the Dart?
You may have to make a hand sized unit with some adjustable
hardened rollers (or use small roller/timken type bearings)
where you can roll it back and forth to get the desired look...
kind of like a portable english wheel
or
You might try an air powered nibbler to do the cut out ( and I know this leaves a single dimension edge), then fab you a "lip" on a roller press and mig it, or spot weld it back in to the expanded well.
Any race car chassis/body fab folks on the board?
Just my .02

Yup, for the dart sport. That is good idea on the weld the piece in.
I thought about cutting two inches out from the back of both openings then fitting a piece in the middle but I am lazy.

[OLDRAT]

Yea, I hear you.
Doubt if you would find any specific parts in a bone yard for that old lady, but you might find a fender profile from something else that would work, then you could cut out a couple of them and fit to your configuration. Might be less time consuming and cheaper.
Maybe someone that's an expert here would share some ideas

so, you wanna tub your ride-? buy big wheeltubs.....
as for using a pinch roller, what for-? bending the outer
fender panels-? you're talking cutting out the stock panels,
and making larger-radii openings-? not hard to actually
make the larger openings and conform to the stock body
lines, but alot of work to cut the stock openings out of the
body, and then weld in the new openings,...... my guess is
if you don't know what a pinch roller is/does, the job might
be over your head already. just my .02, and that plus .75
and you might be able to buy yourself a sode from the vending
machine...

Well considering I used to work at a chassis shop and have done it the other way I was looking for a way to do that was not so labor intensive and then required a bunch of body work, so **** you very much.
