Expanded steel added, along with a center front and top brace, to keep the expanded steel from folding in on itself, and to lock the front and rear structure together. I figure the expanded steel will provide good vertical support for taking weight, minimizing the amount of bracing needed. 13.1 lbs at this stage, which had me hopeful the overall project would compare favorably to a box made of wood.
I would do the top center brace differently if doing it again, but it'll do... The front should have been notched 1/8" to tuck in flush against the top of the angle iron, and the back should have been notched 1/4" since the rear angle iron sits down within the side pieces, for hinge clearance. That way, it would have been level with the perimeter for lid support, rather than only contacting the lid when it flexes down. But, since I decided to go with a thin plywood lid instead of ribbed bed metal, it has the inherent flexibility to make that a probable non-issue.
