Ajbforging Posted August 8, 2016 Share Posted August 8, 2016 So, I've gone through a few different designs, trying to build an efficient coal forge. I started out using a grill lid and putting a mixture of sand and plaster of Paris in it to form the bowl where my fire would be held, with a "airtight" tunnel coming from the side of the lid where I bolted the centrifuge fan I used for my air supply. This design brought me up to forge welding temperature but the "refractory" decayed. I demolished the bowl and decided to go with a firepot made of 1/4 stainless steel surrounded by patio brick. This design was a few steps back and I can't bring my heat up high enough to forge weld and begin folding metal. My question now is, is there a surefire design that can give me the heat efficiency? I am having a hard time believing a brake drum forge would give me ample amount of heat to hear up the metal to forge welding temperature. I eventually would like to attempt to make demascus steel. Which is why I stress forge welding. Quote Link to comment Share on other sites More sharing options...
