Hey diy,

I recently got into blacksmithing and couldnt really find a good site with tutorials, so I took it upon myself to make one.

blacksmithingtutorials.com

check out this one if you want to make your own forge in your backyard:

blacksmithingtutorials.com/brake-drum-forge/

If anyone has any feedback or suggestions on things I could add just leave a reply!

I made a brake drum forge, it was practically fucking useless. Built a decent forge (2' square) and started burning coke beans and it's a whole different world.

Not saying people should run brake-drum forges, but I can see people who don't know any better being put right off smithing after struggling with a shitty forge. If you've got the means to make a brake drum forge then you've got the means to make a much better forge.

hey op, maybe you can help me out

i build my own forge, it works pretty good, but its giving me a little trouble, it keeps building up this sticky slag like substance near the air inlet

also having a tough time keeping the coal in a pile, and the anvil i have has a load of dents and scratches and chips , it ways about 50 55 pounds anything i can do to fix it up, get it some nice edges that won't chip on me (spend like 2 bucks per pound on it

pic related its the anvil, i also took a bunch of the forge

also he's a pic of my shit forge, doing the best i can, going to try using something like plaster or clay to make it better

it used to smoke a lot on me but then i moved it closer to the chimney, and put the concrete block pieces around the are hole which is pretty small about one inch around, works alright like i said but it could've been better if i had found 2, 2.5 inch pipe for the air system but i couldn't so there ya go

Anvil: That's a solid looking old-school anvil, obviously heavily rusted. The only way to repair it is to grind it flat.

Give it a ring with your hammer - it should have a clear tone. If it makes a thud, it's got a crack in it somewhere, and isnt' worth repairing.

Forge: Hard to tell from the picture what's wrong. Is the inlet (proper name tuyere) in the bottom? It's very easy to clog up and block airflow, you'll need a snake trap underneath it. I prefer French-style tuyere's which pipe air in from the side.

There is a LOT of coal ash in your pan. Get rid of it on a regular basis. It causes all kinds of bad things, including slag. Shift your live coal off to one side with your rake, and scrape the ash out. No need for a deep clean if you do this often.

Slag usually comes from metal detritus mixing with coal/ash into those glassy crap things. Expect much more of them if your fire is not burning clean, doesn't have enough O2, or if you heat metal to welding temperature (sending off sparks). It can also come from low quality coal. Just clean them out with your ash, above.

Coal and Slag: You need to practice making a good coal fire. First, fill your pan up with coal. The whole thing. Your pic shows a little bit around the center, that won't do. You want a huge pan full of the stuff.

After you start your fire, start building the coal into a mound. It should melt together into a semi-solid igloo sort of thing. This is a 'closed' fire. It makes the highest temperature and burns the cleanest. Poke a hole in the end where you want to stick your work - or both ends if needed to pass a bar through. As you add coal, start the fresh coal on the edge of the mound and gradually push it into center as it burns. This will burn out impurities before they get into your heating zone, this keeps contaminants out of the metal, allows higher temperatures, and reduces slag as well..

For larger pieces, make an 'open' fire. Make two mounds side by side, and with an open heating zone between them. You'll burn through lots of fuel very fast, but you'll get a larger heating area. Because it's open, this is an oxidizing fire, so it will make more slag and is not suitable for welding.

When you are done for the day, mound up all your still-burning coal and stir it in with some fresh stuff. Sprinkle water on the mound (do NOT pour) and stir until it's got some wispy smoke trails but no glow (in the shade). Let it smolder out for a couple hours. This will give you a mound of fresh coke (impurities already burned out) to start with the next day.

Lastly, never, every pour water on the coal until it's wet, or leave water in the pan. It will mix with the coal ash and form sulfuric acid, and eat away the bottom of your forge in no time.

getting the air to flow into the side would fix a lot of the problem i think im having,


also got about 50, (though really used a lot of it already so down to like 40 i think bought two boxes of anthracite coal for like 5 box off ebay

ill go to the forge here and try some of that stuff,
ill try and get an elbow on the inlet pipe so the the air vent doesn't get clogged up like its been doing, il post more pics from the workshop once i get the forge going

so guess ill post in about 30 mins if i can get my camera working

well\
got a few pics of it running
wasn't able to get the french vent in

but i did take your advice and made a shit load of coke, got a REAL nice heat, actually.. a bit no much heat, i burn the metal a little, but the forge is a real hassle, going to keep at it, probably going to buy a new forge in a few months probably in like. october
because its really fucking shitty this little thing but, going to have to get a little elbow for the "tuyere" but it works pretty well, going to also buy a phile, and work on the anvil, i strike it and it make a "tink" sound its not really a thud, and it doesn't really ring , its just a high pitch "tink"

really wish my phone would of let me post when i was out there

This is a table I'm making. I know it looks wonky, but it's actually square the ground is just uneven. The legs might be a but uneven though. Have to work on that

should also mention

all the "iron" metal im working with are holo pipes

they are not fun to work with, though they are pretty easy to shape

>>644840
looks pretty dude , are you going to make an inter framework to lay boards over so it will have a nice rustic tabletop

It's going to have metal slats on the top.
>pic slightly related

It will also have a shelf that I'm going to lace on with 1/4in rod. This table is just over 2 foot square and will probably weigh over 100lbs when I'm done.

For a french tuyere, get a bit of heavy ass pipe, heat it, and hammer it down to a 1/4 in flat opening. Hopefully you can mount it somehow or other abotu 1" off the pan floor. Yes it will get red hot while you work. Expect to replace it from time to time, or grind some slag out of the opening.

For one on the bottom, get a cast-iron forge grate from a forge company or your local horse / shoe supply store. A steel grate won't hold up nearly as long. A T-joint with a removable cover will be a good enough trap for ash. Don't rely on threaded pipes, the constant heat expansion will ruin them.

Fire: If you're melting your metal, you've got a good fire now. Practice and learn to control the airflow. Turn the air off while the metal isn't in the fire, no need to make a blast furnace :P

Fire looks good, good crust on the top and good coal color underneath. Lots of smoke - you may be using too much fresh coal. That's really hard to tell from a picture though, since I can't tell where in fire the smoke is coming from. You'll have to judge that yourself. Ideally, you'd be able to remove most of the bricks and use your coal mound itself to hold in the fire once you get good at managing the fire. Putting a couple heavy bits of metal like 1" bars on the bottom of the pan around the tuyere can help stop the fire from creeping around the pan if you go this route. Although honestly, if you like bricks, use em. It's your fire.

Looks like you're off to a great start. GL
