Building a Blacksmithing Gas Bottle Propane Forge & Burners

  • Published on Aug 10, 2017
  • It was time to upgrade to a gas forge to give some more heat control & efficiency vs my old charcoal 44 gallon forge. I bought a brand new 9kg gas bottle to use for the project. The burners I fabricated based on a design by John Carman.
    Safety Notes:
    - IF you use an old gas bottle, take extended precautions to make sure it's empty before cutting into it with an angle grinder. Better yet, buy a new one, they're cheap
    - IF you use galvanised components for your burners, like I did, ensure you remove any galvanising before using the burners. Both inside and out
    - ALWAYS wear a respirator & gloves when working with the insulation blanket until it has had a rigidizer applied. Do not light the forge without applying this.
    - This is an inherently dangerous project - take all safety precautions when constructing, working with propane gas and operating a gas forge. IF you're not sure about anything, then don't risk it.

    Due to popular demand, here is a list of components used in the burner and gas manifold construction:
    20mm x 40mm (3/4” x 1 1/2”) bell reducer x 2
    20mm x 25mm (3/4” x 1”) bell reducer stainless steel x 2
    20mm x 150mm (3/4” x 6”) pipe nipple x 2
    3mm x 100mm (1/8” x 4”) pipe nipple x 3
    3mm (1/8”) tee
    3mm (1/8”) 90 deg elbow
    40mm x 100mm (1 1/2” x 4”) pipe nipple
    0.6mm (0.025”) mig welding tip x 2
    3mm x 6mm (1/8” x 1/4”) nipple
    6mm (1/4”) female/female ball valve
    6mm (1/4”) male to 3/8” male flare fitting/adapter
    Added since video on gas bottle side of ball valve:
    0-60 PSI pressure gauge, 1/4” male thread
    1/4” tee
    1/4” x 1/4” nipple

    Due to popular demand, I have updated the video description to include a list of components used in the burners and gas manifold. Happy hunting!

      How hot do you think does it get? Can it also be used for burning ceramics?

      Hey, what you did there was extremely dangerous! You are lucky that this gas tank didn't explode! You mustn't grind or bore or something like that on a gas tank without havinging filled it up with water before!

    I get that you explained that you bought a brand new gas bottle but you might also want to explain why that is so important. Someone thinking they might save themselves a few dollars and use an old one that has held propane might be in for a very explosive experience. As I know your intent would never be to cause harm and strictly to share your build...…. you should remember that people of all ages might be attempting your project. Other than that.... good project.

    Really cool video. Love the music. SUPER great instructions. I use propane tanks all the time for projects as well. Got some really cool fun with fire tricks. Hint. And use them for pressurized water tanks for my DIY air compressor powered pressure washer for portable use. Hint. I really enjoyed your video and would like to invite you to check out some of my playlists I think we're like-minded. Have a great day.

    Great Video. Question: Why didn't you just use black gas pipe type fittings instead of going to all of the work to dip and clean the galvanized.

    Why don't you buy black iron fittings and nipples and not have to deal with the galvanize.

      It is possible to purchase a propane bottle that has never had any gas in it. I suspect that's what was done here.

    Hey! great build! two questions: 1. Is the threading for the copper welding tip 1/4" 20UNC? and 2. Is the threading on the converter 3/8" special (as in the propane hose has a finer threading than plumbing threading)?
