Once we were happy with the fit, we took the front cockpit tube, bent it to shape and then cleco'd it to the body. (That's the cleco you see sticking out here.) Then, we took a little tube and fit it to the cowl tube. We then lowered the body down onto the little tube, measured everything, and then...

Then you tack weld everything into place. Tack weld means very small weld--so it isn't so hard to break when you have to reposition the tubes because you measured wrong... :eek:

Here is a close up of the center cockpit support tube. Notice how it is already perfectly notched courtesy of our mill.

Perhaps our fiefdom lies outside familiar pastures.

You have to check, check, check to make sure things are right and square.

Here we are checking the "Z" axis height of the body relative to our CAD drawing. It is right on the money.

Here is the tool we used to measure with. You see Sandwich using it in the previous picture. Because we had to measure around the radiator to our datum, we sheared a piece of aluminum exactly at 11.4 inches long. We made sure the edges were perfectly square then we could measure over to the body.

When we are very sure everything is perfectly square--we weld again.

We write all the measurements down on the car so they can't get lost or walk away. Everyone knows what the measurements are and everyone knows we expect things to be as perfect as possible.

More notes on the CAD dimensions.

I'll sneak another MTV YouTube in about now.

I'm really bad at following directions. Just ask Jamo.

Great work.
The real question is this: Is David (Dr. Billet) & Company-- reinventing a simple Cobra Kit car or are they creating one of the finest pieces of art I have ever seen? (Yes, I have seen alot) It is almost a shame to put a body on it!

The project is planned as a one-off. I think it would be prohibitively expensive to sell these as a "normal" kit.

Everyone who sees the car says it is a shame to put a body on it. I need to think of a way to make the body easily removable. Now, that will be a trick that will probably not be possible. But, as you can see, I love a challenge.
