Internal Repairs on the wood cookstove

This morning I spent time rebuilding the interior air baffle that "turns on the oven heat". When open, smoke goes directly up the chimney. When closed, it forces smoke to go around the oven, heating it up before going up the chimney. The fire box got a new layer of high heat ceramic wool insulation, the same kind used in metal working furnaces. The shiney metal sheet side is towards the steel walls. I have placed some recycled brick in it to see how it will look when done. With the bricks I'm choosing, it will give a deeper fire box so we can use longer pieces of wood.
