I plan on using the forge for knives, decorative pieces, hand tools, that kind of thing. I recently saw a forge made out of a refrigerant tank, that looks like the size I would want. I plan on lining the inside with kaowool blanket, then ITC-100 or something similar. I was planning on using firebrick for the floor of the forge. I was going to use kaowool board to make the openings on either end of the forge body smaller but still have an opening on the back (exhaust) in case I make something longer, I can put it threw. Let me know if this sounds good.
