About a year ago I decided I wanted to build a TIG welded aluminum Mono chassis for my GT40. I know there is no good reason to build a new frame when the one you have is perfectly good but I like to learn new things and this seemed like a great way to learn. I have admired Frans design for years and have told him several times "man I wish I had thought of that!" After talking with Fran and explaining my reasons I started my design. After making all the sketches I needed I worked with Pete to create a solid model in CATIA to work out the details. I will attempt to share this chassis build with you as I have time and answer any questions. I have been working on this for about one year now so I'll attach pictures showing what has beeen done over that time.
A very sturdy frame jig was made using 6"X6" wide flange I beams. The sponsons were fabricated and welded. The floor pan was cut out along with the parts for the engine compartment. The sponsons were located to the floor and tacked in place. The transverse bulkhead was then welded in connecting the floor to the sponsons
