I have decided on a paint can forge should suit my needs for heat treating the blades I intend on making. I’m not going to be welding or forging any blades just heat treating blades from a 2 to 6 inches in length. So I don’t think I will need a hardened forge floor because I’ll just be setting small blades on it or holding or supporting them on a rest. 2 layers of Kaowool insulating blanket all around the inside and back wall with an extra cut to form a flat forge floor. Buttered and “Rigidized” with fumed silica. Then the inside will be coated with either Plistix or Metrikote. That in a nutshell will be the forge hull. I’ll close down the front with a couple of insulated fire bricks if needed. Now my big question is how to get it hot? A Propane torch? Maybe use a 3/8th or a 1/2” “T” burner, “Z” burner? Heck maybe something else? I have a grasp on how to build the burners, but I haven’t a clue on what size orifice to use on burners that size. I have read countless post about burner theory here by the masters and my head is melting.
