To do reverse curves would you have to stretch the outer edges befor running it through? What about regular curves , shrink the edges first and /or stretch the peak areas of the fender? The moving picture show of it's magic would be fantastic.

Don. The principle of what do sheet metal is probably clear to us. In my EW, it works in reverse curve. If you push sideways, it bends more.
But what makes the "mythical" olive no one has seen.

So far still an archaeological fairy tale.

I'm really curious if anyone will provide a video for better imagine.

I asked Bill Longyard if he knew of a video and he does not. However, he said he will be going to Awadi's shop in September and will be sure to take some video of it in action.

Thank you, Kerry. The machine is a rarity, but nobody actually knows what it is good for. And because "The devil likes details", we are interested in details.
To think means to know nothing. Exact description of machine operation.

Well I was wrong. That is the video I originally saw and obviously it does a reverse curve.

Super Mike. Thank you. "Beautiful Prince Kissed Snow White" ...
I wanted to know how it works.
Reverse curve. Yes, it easily makes a reverse curve.

My 2 wheels for EW can do the same thing. It is very well possible to control the deflection and bend some part more or less.

Yes, that is the video I remember seeing. Awadi is looking for the original for the non-Facebook folks.

Jaroslav, your ewheel setup is a small version of the same thing.

Another way to make reverse curves is to use the Pullmax etc with 'Hot Dog Dies'

Kerry. I saw your video and led me to my thoughts.

I have the great advantage that I can use the greater and more stable power of my great Eckold. I used the rubber tool at the bumper 3mm stainless steel to straighten the shape. A reverse curve was automatically created when pressing. The rubber tool (hockey puck) straightened her without visible traces.

Recently I needed to produce a reverse curve and I thought of the shape of the pulley in the photos. I attach a photo of the first attempt for it I used pulley without bearings. She was lying near my hand ... And for try it was good.

The round profile of the bottom tool makes the deep trace on thin or soft sheet metal.
