pic: Concept Frame

[EricH]

Looks almost like the one 330 did for the 2006 season...we moved the end rails farther in. For 2005 and 2007, we had three rails for mounting purposes on the inside.

Some pros and cons of the design:
Pros:
--clearly defined "keep out" zone due to the double rail
--strong
--simple

Cons:
--weight (those top bars add a lot--if you can remove them, do so.)
--Welding is virtually required.
--As drawn, the frame could bend if it takes a side hit. Consider adding inner blocks where the wheels won't go. (Which will also render the top bar mostly unnecessary.)

I would add a thin walled crossbar from the left front to the right rear, this could add some cross support, while also adding a light way to support a sheet of lexan to hold the electronics. This can also be done with a flat piece of aluminum.

hmm... did you draw that in google sketchup by any chance?
