Hi David,
I'm planning on making the body from carbon fiber, I have an idea on a new process to add a little strength, (still playing but it looks as thought it will work) After searching for an off the shelf chassis, nothing is really tickling my fancy, exept yours. So I'm thinking about making my own. I just ordered some books on how to design a chassis. My latest thought is to make something like yours with either steel or aluminum ends connected by some super strong carbon tubes, they are awesome(I built a trade show booth for the company that makes them)
I'm glad I don't have the cash to pay someone to do this for me. It is too much fun. From what I've seen I don't have to tell you that. Congratulations on the new CNC, I've got an old 4'x8', I'm thinking about upgrading to something with a tool changer.
Keep Having Fun!
Chris
