  1. The Johnson is a huge waste of gas at today's prices. I count my usage of propane in gallons per hour, literaly. I would either build a forge or buy an efficient one and forget the Johnson.

    If you were doing production and needed a lot of irons in the fire, it would be a different story.

    For a propane forge, you do'nt need a blower.


    The compartment is not that big in comparison to propane forges. It uses 90,000 btu's to heat to 2300 deg in 50 minutes, which seems like a long time.

    would you consider that to be heavy gas usuage?

    I could add a bad door to increase the usefulness. I wouldn't pay $500.
  2. An employee taught me how to stick weld on various carnival equipment. I have built many semi trailers for the business and eventually in 1968 my dad acquired an Oxiweld mig system with a yard arm that we still use today.

    In the late 40's my dad worked as a machinist but decided to enter the carnival bus. full scale. I recall him welding a kiddie swing ride and beating on the welds with a sledge hammer to prove to him that he knew what he was doing.

    Neither of us ever had a weld fail.

  3. Standard fire brick forges are usually gas hogs with long warm up and cool down times.

    The large Johnson's I have seen are more industrial forges and not a good choice for someone starting out.

    I skipped the middle man and bought a Johnson heat treat forge/furnace (Pedestal model) at a school auction in Columbus OH for US$40.


    Sounds like the same model I am looking at. How would you evaluate it for someone starting out? Did you need to redo the brick or coat it?
  4. The white and green is connected on a home buss panel but I had to consult the Nat. code one day and found that outdoor house trailers and such need to have the grnd (green) and neutral (white) isolated and not on the same buss bar.

  5. I have a 3 phase hyd unit I could use but some yahoo threw out a couple of heavy hyd. cylinders. I have been around many hyd. systems so I may attempt to plan on a build.

    I had some european 18" dia. air cylinders but I think those are gone also. I still have a larger air comp. that is not being used but it is still expensive to operate.

    No forge, no oven but a strong interest.
