Bill,
Don't make it too complicated. Guys have been rolling fenders on race cars using the baseball bat technique for decades. Its simple, it works, and it's not rocket science.

The fender rolling rig makes it a little more sophisticated, but the net result is the same - apply force to bend the fender lip towards parallel with the fender skin. The lip does not know if a bat or a roller is applying that force.

I'm all for simplicity, but I'm only worried about weakining the fender at the edge and have it deform. I've seen a few cars where that happened.
If it was a track only car I wouldn't care.

If you pull sideways on my fender lip it hardly moves. If I folded it I would worry that it would deform and retain that shape.

I guess I just need to look at one that has been done.

So what's the short story on roll bars and cages for Cabs?
Does anyone have any links to different types?
Can I get one that leaves the mounting plates in place and remove it for street. What's the wall thickness of typical tubes? Is it possible to use smaller diameter steel with thicker walls?

Bill -

If your rolling the fenders to fit bigger rubber, feel free to stop by and borrow my 8s if you think you'll go that route and want to make sure they'll fit.
