    This is a sub-project of my crossbow project. I needed a way to forge parts for my crossbow so i built this forge.
    Any comments, advices and questions are welcome.

    Nice forge! I too built a forge from a brake drum. Works like a champ.
    FYI , if the hair dryer you are using does not have a cool setting, you might need to remove the heating element. It gets pretty hot and will melt the hair dryer! Learned the hard way. I use a small shop vac for my air supply, with a ball valve so I can regulate the amount of air flow.
    I noticed from your picture it looks your burning hard wood charcoal . Be careful, the sparks can start a fire. Check on eBay, there is great coal you can purchase fairly cheap.
    Great job, and happy forging!!!

    that's a nice forge. for folks just needing to forge a few parts, they can attach a large tin can with a hole cut in the side and holes poked into the bottom to a section of stove pipe. you can either stand the pipe up on a fire safe surface or suspend it between two trees or post. if it doesn't get hot enough simple add more stove pipe.

    for mine i used the stove pipe idea, but added a front tube/burn chamber and replaced the stove pipe with oil drilling pipe. i added a trimmed down 6" damper to control the air flow. no blower is needed since it is a rocket stove.

    Nice panne, would like to see pictures of the entire forge. How about some details on how you constructed it also!
    Very nice indeed!

    i'll post the sucky forge details in a separate thread. due to steel beating being highly addictive, i'd have to say most people won't be satisfied with a small rocket style like mine. the forced air brake drum design allows you to make much larger and complex projects.

    I really like this forge. Something I too want to do is learn smithing, but I too have issues with neighbors, and no nice back yard to play in.

    Thanks everyone :-)

    @jds6 - Thanks for the feedback - the hair dryer doesn't have cool setting so after a while it's stops working and return to function after it cools down. I plan to disconnect the heat unit since it not necessary. But I might upgrade it into vacuum cleaner. Nice tip for the ball valve, I might use it. And also the coal looks like a good advice.

    @panne - that's a nice forge you built, very innovative!

    Drum brake forge Empty improvement

    Post by ZigiMan on Thu Feb 28, 2013 5:40 am

    I added a little improvement to the forge - fast and easy way to turn on and off the hair dryer. I built a jig from a light switch that enable me to control the dryer by foot.

    Some new improvements:
    Bought coals which produce more heat without sparks (as jds6 advised me).

    Since the drum brake I have has a shallow hole I wanted something deeper. Took used fire extinguisher and cut of the head (the handle and spout) and cut it again, a little bit down from the top:

    And welded it to a plumbing connector.
    Here is the forge in action:

    So now it should be called: "Fire extinguisher forge" Very Happy

    Anthracite shouldn't smell bad, but some kinds of bituminous certainly can.

    So the quality might be the issue. I wasnt aware it could differ that much. A friend of mine works at the harbour moving cole from a ship to trains. I asked him to bring me some, i thought that would work fine. It burns great but is smells really bitumonous indeed, thick yellow smoke etc. I can throw those away i guess. Anthracite is a thing we do have at work (Steel-mill). I might be able to get me some of that, just have to figure out which quality that is i guess. Thanks Ken, i should have done my homework a bit better i guess....

    Greetings all
    When selecting a coal for the forge, you want to find a good smithing coal. This is a high quality bituminous coal. It is basically free from ash, sulfur, and other impurities as possible. The constituents of the coal should be as close as follows:
    Sulfur - Not over 1%
    Ash- Not over 7%
    Carbon- Not less than 70%
    Moisture- Not over 12%
    It is hard to find smithing coal to these constituents, but there are places that come really close.
    By the way, nice forge Zigiman!
