E-Wheeling Shelby Cobra Bonnet

[longyard]

Hi all. I hope to be posting a few more "how to" videos the next week or so. Here's the first. Mark Gerisch rolls a Cobra bonnet in less than an hour. The video is just over 20 minutes.

Thanks for posting that Bill, I enjoyed watching it and particularly liked the 'picture frame' analogy and blending in the edges once the shape is formed.

very interesting .. i notice it took the student a little time to get his foot work right if you noticed he was walking in small steps but toward the end he got the hang of the rocking method ..

A great video! What is the purpose of 'pinching' the sides together (pumping?).

Noobie questions maybe somebody can help me with:

Why is he very particular about how his partner holds the panel? Wouldn't the same shape be induced either way? Is he trying to get his partner to induce a closer to final arrangement while adding shape?

I typically wheel alone, and the other end slips on larger panels, but it seems like my shape doesn't suffer, only arrangement.

Nice video Bill.

I was hoping others would get in on the tutorials thread.

If one were to planish a spot on a sheet of metal using a hammer on top and dolly beneath, this may add some stretch but things don't change all that quickly as the metal has not be persuaded very well in which direction to go.

Now take a sheet of metal on a shot bag and strike it with a blocking hammer. This has given the panel a bit of stretch, but also given it direction.


RE: the helper holding the panel in tighter at the front of the panel, the hood has more crown across the front edge than the back edge, so it is being given more persuasion.
