I am new to this forum and to forging itself, so please bear with me I have always been fascinated by the concept of molding metal to your will, into things that you imagine and can use afterwards. (A cool sword with a scabbard is my end goal) I chose a solid fuel for my first forge and I can't seem to get the charcoal hot enough to get to red for whatever reason? I know I should easily get orange/yellow temperatures with steel, but for some reason, which I suspect to be my air supply, it's just frustration and a lack of forging going on. I'm using Crown Oak natural charcoal (broken into 1-2" pieces), hair dryer, 2800 degree rated fire brick (2 or so inches thick), and a 2-3/8" chain link pole cut to size with slots pointed to the fire (side blower). My very first attempt, I used a metal vent metal thing with hose clamps for a tube, pointed directly into the briquettes (again I switched to real charcoal) and managed redish/low orange heat but ran out of fuel halfway so I made a compromised butter knife haha. Now, I can't get even red heat for some reason, and I feel like I am going crazy. The first forge was just inn the dirt with walls and a ceiling. The new one I built a little higher and made the floor, walls and ceiling out of brick now. Again, I suspect air flow is the culprit as the amount of charcoal isn't a problem (micro tabletop forges got orange heat that were inside of a literal bread pan). I don't know if I need more air flow and/or volume (wider tubes?) Yes, I looked for classes and they were booked until October near November and I would lose interest by then haha. I might try joining a blacksmithing group in plain township (Ohio) if they have one so they can help me out? Was also looking at a simple forge like this as I don't want to fork out 150-250 dollars for a welder for a brake drum forge. I very much want to explore this craft as I've basically not started it technically. I am slightly discouraged, but I don't give up that easily haha. Here is my sad, deformed, scratched (but shiny) butter knife I made, which, I am oddly proud of. The plus is I used a bolt, so it has those serrations that look cool (which I totally planned for... yup) Mind my hound lol she wouldn't move. I was also wondering about this mask I bought for zinc fumes. H.zip
Hey there. I am absolutely crash-coursing into forge making and metal working. I've gone through several crude forge designs and worked up to my current concept, that is a bit ambitious. I am having an absolutely ridiculous time getting by burners working properly. I am going to attach pictures to show what I have going on. Basically I have a 36" can lined with fire brick and refractory cement, that part holds heat so well! Then I use a 20# tank, low pressure regulator off of one of those tank-top heating burners, 3/8 OD hard copper lines, going to .35 MIG tips for burners. I have tried anywhere from 1 to 6 burners, different amounts of air holes in the 'venturi' area. So many things. Last night, with this setup I had two burners spaced about 5" apart working quite well. Finally all blue flames. But it's very temperamental and seems to end up choking itself out. When they work, they work well - but it's only in tiny spurts of good fortune. They definitely seemed to be running way too lean, and I increased the venturi holes by 400% and that is what really set it running better than ever. The second burner from the entrance chokes back too much though, and basically was only heating steel red-hot under directly under the first one. Running only one burner seems to just be too much gas. Two works the best. Should I have a flare on the end of the tubes? I've seen mixed things about this. Do I need to open up the back end of the forge... with more than 2 burners, and even with two sometimes there is excess fuel going into the chamber, and will sometimes choke out the flame. My main concerns at this point are should I have flares on the ends, and is it reasonable to think I need to knock a brick out of the 'back' wall to keep back pressure from building up in the chamber. Please help! I've wasted hundreds of $ already on parts through my trouble shooting and I'm admitting defeat. This is just way too complex to simply teach myself like many things I've done.
