The reason I went with 1/4" lexan instead of 1/8" aluminum is weight and time. With going with lexan, you don't need to do cheese holes. I have not done any stress analysis. This type of chassis with lexan sides has been proven for many years with 1126. Take a quick look into my pictures for reference. I like to design chassis that anyone can build. This is easily built for teams in a wood shop with very basic tools.

I just stayed with 1/4" lexan because that what we have in the shop at the moment. I am sure we could get away with 1/8" instead. It does have 4 mounting points on the front and rear rails and 2 points per inside rail.
