Got more aluminum today, and couldn’t resist haphazardly laying it across the top. The bottom aluminum bar is 1/4″ think, 12″ X 16″. The top bar is 1/4T 16″ X 6″. And the two aluminum finned heat-sinks are 1/4ish” thick + Fins = 1.2″ish thick, 8.5″ X 6″. The final product will be trimmed accordingly, and sandwiched together using aluminum round bars as posts.
