  1. You are correct about the different heat content between natural gas and LP but when I first installed the furnace in my workshop 6 years ago I bought an LP conversion kit from the manufacturer and installed it. It involves changing all 5 jets and putting in a new pressure regulating spring. Then I used a homemade mannometer to set the pressure to spec which is 10” of water. So it’s all set to go from that standpoint. But it does sound like I should start with a conventional design and store the heater burners for another use. I sure hate to throw them away. Thanks for the help and advise
  2. I had a suspicion that using the 5 burners would not work properly which I am asking the experts. But it looks like such a nice unit I couldn’t just throw it out. What if I just build a heat treating oven to get blades and shafts to around 1900F and quench them? Or is that no better and I should just throw the burners and regulator out and use a proven design?
  3. I’m mainly a woodworker but I often make my own tools out of annealed O1 tool steel I buy and then I heat treat them with an acetylene torch. I’d like to build something closer to a Forge to use both for heat treating and to try some forging. I don’t have any experience with Forge building other than back when I was a teenage mad scientist I got hold of a large steel artillery shell, drilled a hole in the base and put a blower in it which allowed me to burn a charge of charcoal in it at enormous temperature. Recently the propane heater in my shop went out due to electrical board ignition problems. I put in a new heater but now I’m thinking the burner setup in the old one might be salvaged and converted to a Forge. There are 5 burners with Venturi tubes. The whole unit has a rating of 75,000 BTU. The burners with tubes as well as the regulator can be removed as one piece. It’s spark igniters could be activated manually with an ignition coil. The blower could be salvaged as well. I would use steel plate as a housing. Does this sound like a workable plan or should I start from scratch? i will try to post pix of old heater burners
