Re: Plastics

We used 1/8" 6061 aluminum sheet that we routered out in a rather minimal diamond pattern, leaving mounting locations for electronics and things, and it came out to about 3.7 pounds if I recall. It was quite stiff.

I like doing this because the bottom pan serves as the welding jig for the frame rails and crossmembers. It helps line everything up. We rivet the side rails and crossmembers to the bottom pan, then weld the joints.

In 2012 we used 1/8" ABS which was okay, but a little soft and flexible. We had to brace it.
