I do have a question for you. In the build manual it shows your Polish guys building a rear fender by slapping the aluminum down over a hard solid male die while the edges are clamped. What is the material your dies are made from? How did you make them. I'm impressed that your guys could make such a large panel in one piece. Obviously there is some welding of subpanels going on but still, that is a unique way (at least to me to shape the reverse. Two of our members, Rick Tucker and Rhondo, stopped by your facility last year during the build of this car. I was impressed with the tour they were given. Your crew taking the time to do that certainly builds goodwill! A few years back there was a guy named Chuck who scratch built a Cobra Coupe and documented the entire build. Unfortunately, AOL changed it's storage policy and the data is no longer available. A huge loss for the metalshaping community.

We use TIG for small sized repair work or to finish off the end of the panel. David |

We make them any number of ways--by hand, CNC, cast the concrete, whatever it takes to get the shape we want. We use this method because it is MUCH faster. Also, we are able to make a much smoother car in the end than by using a wheel or some other method. Also, it doesn't require as much skill as the wheel or a Yoder. You can learn it pretty quickly if you are determined to make a good part. Granted, we have years of experience so we know where to hold things and where to hit things. We didn't make mirror bodies over night. David |

I glanced at the book -- and then downloaded it. Printed via the color laser and 3-hole punched and placed in a binder. I have my reading material for the plane rides next week!
I'm definitely impressed by all the CAD work involved to create the chassis. And then the followup machining/fitment of everything -- this was a giant task without question. I'm getting involved with both of these as of late for upcoming projects and I will admit it is a large task to accomplish as well as getting a mindset to trust it will all work. (I'm used to the old world method of fabrication and forming) Questions for David: (I haven't read the PDF's so hopefully the answers aren't already within) 1) What was the biggest mental obstacle in making the project happen? 2) New Technology -vs- Old World Craftsmanship -- what did you learn about the balance between the two and application thereof to upcoming projects? Thanks for the book in PDF form -- it should be a good read!

We used new technology where ever possible. The one thing in the project that impressed me the most was how everything fit together when we were done. CAD is amazing. I won't do another project without it. David |

David, do your 'standard' cobras also use the 3/4 aluminum tube substructure?

What you say is exactly right but of course it would not be economical to make one off parts or bodies in this way, which is where traditional methods like the wheeling machine ect. come in. These methods are perfect for low volume production, each part will be the same, less skilled labour, faster production but much higher initial set up costs. You also have the lower labour cost in Poland which makes these cars viable. David

On the billet car we used aluminum because the whole chassis was aluminum. David |
