I am a newbie blacksmith and want to build my own propane forge. To do so I recently aquired a air compressor that is 16 inches wide and ablut 24 inches long. I want to insulate it with 2inch ceramic blanket, cover that with a half inch of refractory cemnt and line the bottom with fire bricks. The problem is I do not know if I will be able to reach forge welding temp with how bug of a space I will have? Any I deas on how I might redesign are much appreciated.
