In my continuing quest to use readily available manufactured materials for stove construction, here is the steam pan charcoal stove with "perforated lollipop" air control. It is a 1/6 size steam pan (roughly 6" x 7" x 4" deep) inside a 1/2 size (roughly 10" x 12" x 6" deep) with 1" ceramic fiber board insulation between. The charcoal chamber is lined with expanded stainless steel to extend the life of the inner pan and improve air flow. Army surplus D rings are used for pot supports. Threaded rod for legs. It can be easily disassembled for repair. It has a small charcoal capacity like the BURN's Jikokoa (formerly Tank).
I plan to eventually build a two burner version in a full size steam pan.
