FREUD, I don't know what chalk on the floor is. I do know what a dry board is though. LOL If you give that tree picture I am sure we can get the tree house handled. But no mechanical drawings for the elevator to bring the LSR car up.
This is not my car, a few us are helping a friend with his car. It will be community car and will have several engines (the IRL engines are mine). Its very easy to maximize everything without spending any dollars. So far all we have in it is time and the few pieces that are taken from other cars. Having a clean sheet of paper to build the car will let us try some ideas out on the computer before we build. When I built my gas roadster I did some CFD ( a lot cheaper than a wind tunnel, even though I would like to go use the tunnel some time next year) work and found the area around the cockpit was crucial to the way my head rest faring was designed.
I do know what you mean though about chalk on the floor, we have almost 30 drawings for the suspension and related parts. Most will need a CNC.
By the way do you have any pictures of John Helash's Mustang with the 427 SOHC engine at Bonneville in '71'74.
