On my trip to Haiti in March 2016, I finished the ammo box stovetop oven. It is made with two ammo boxes, ceramic fiber board insulation, some stainless steel sheet, and various hardware. The oven chamber is 13" x 13" x 5". I plan to add split firebricks on the floor for use as a pizza oven. It fits on a household rocket stove but could be used over virtually any heat source.nike black leather school shoes clearance outlet
