Most REDNECK Forge Ever. Period.





Introduction: Most REDNECK Forge Ever. Period.

About: I am Jake and I make. I build awesome stuff out of simple materials, mainly dealing in the dangerous. Knives out of RR spikes, guns made of plumbing pipe, flamethrowers with coffee creamer, a cannon that sho...

I wanted to forge a knife.

But my old forge got scrapped. (Not that it was anything special. It was junk. Like most of my forges.)

I needed a forge. But I felt lazy.

So I grabbed a sink. And forged a knife.

WARNING: This is the lamest Instructable I've ever made.

Step 1: Video

Step 2: Cinderblock Base

You need some sort of platform or base to set up the sink (ahem; forge) on. It must be solid enough to support the weight, and have a gap underneath for the drain pipe to go down, so you can attach an air supply. It should also be heat resistant, as forges tend to get hot.

I had a few cinderblocks sitting around, and they seemed like the logical choice.

Step 3: Duct Tape. Lots of Duct Tape.

Duct tape is just the bestest stuf in the wurld.

^^ misspelled on purpoise

I know you think I'm nuts, but hey, it works. No point in wasting time and money buying pipe fittings. This is a quick-n-dirty forge.


I connected a metal pipe with a 90 degree angle to the drain pipe on the sink. I'll connect my air source to that.

Step 4: Hair Dryer Hacking......

There are a few choices when it comes to an air supply.

Hairdryer, leaf blower, heat gun, air mattress inflator thingy, etc. I went with a hairdryer. Mainly cause it was the only one I had.

Yeah, I just duct taped it to the end of the pipe. It works. You can be fancy if you want to be.

Step 5: Bent Wire Thingie

To keep the charcoal from falling into the drain, I crunched up a piece of wire fencing and stuffed that in the hole. That will keep any large pieces from falling down, and the smaller bits and dust should be kept out by the air blowing through the pipe.

Step 6: Fire Up the Sink!!!!

Wow, done already.

The forge actually worked very well. I was able to get up to forge welding temp easily and the sink help up to the heat just dandy. For forging out small stuff like knives, this is a very viable option for the monetarily challenged.

Or for those who just want to throw a forge together and start bladesmithing.

See ya' in the next (hopefully more interesting and better documented) project!

    This is a very cool project... or hot... ;)

    In any case, when you are done you simply turn on the tap to shut the forge off, don't you? XD

    How else? I'll tell you one thing this is good for; brushing your teeth on those cold winter mornings. Not only does it keep your face warm, but you get a nice suntan. People pay big bucks for that.

    You should really put a disclaimer on here. I can see a lot of idiots trying to use ceramic sinks, like this guy questioning a toilet. Toilets and other ceramics will EXPLODE with that kind of heat, due to air pockets. DO NOT USE A CERAMIC SINK OR TOILET!!

    the ceramic if it is not properly kneaded will explode through the air pockets, but when it is in the factory oven, not after

    How does not knowing about air pockets make someone an idiot, smartypants?

    ceramic does fire at very high temp but in a kiln so stuff cools slow and does not crack or BLOW UP like you said it is like you say not a good idea!

    I dont think it will explode. Porcelean fires to 2200 degrees F. And if there were any air pockets it would have exploded in the kiln. Maximum wrought iron forging temp is 2500, so you may see some reaction, but i dont think explosion is the risk. (Lots of ceramic firing experience, zero forge experience).

    Keep in mind, its true the metal melts at 2400 degrees, but the forges themselves generally get quite a bit hotter. It doesn't take long to get up to steel's melting temp with the blow dryer on high. Don't ask how I know :(

    That is a very good thing to point out. Never heard of them exploding, but makes sense. I'll cross toilet off my list.....

    A ceramic toilet or sink could explode. Only use a steel or iron sink, which is likely to have a ceramic coating.

    Alright fellas, i'm curious now. Anyone actually seen a ceramic sink or toilet explode? Or is this just one of those pieces of advice that everyone hears and passes on? I could certainly imagine one exploding, makes pretty good sense to me. Anyone actually seen it happen?

    All ceramics have to pass through a furnace at a very high temperature, if it is going to be waterproof it has to pass the 1000 degrees celcius, and I know this because my mother is a ceramist since before I can remember. In summary, the ceramic does not explode if it is cooked or properly kneaded.

    Thank you! I hate it when people do that. Advice without the experience to back it up is so much hot air that it could probably be used in this forge.

    I think this is an ingenious use of found materials. if it didn’t explode I think you can say it was a good idea. It’s a good design for a forge, but just any sink may not give you the same results.

    now I'll have to look through my junk piles to see if I have a suitable similar fire box, tried fire brick but they were problematic. thanks for sharing .

    I do not know about exploding but I doubt a porcelain sink would hold up for very long to the uneven heat of a fire in it. the stresses would probably be too much and would break like ordinary glass would. they make high temp porcelain lab ware but they are different than ordinary sinks

    Awesome - I may have to try this. Thanks for sharing. And nice touch keeping the faucet in place.

    Thanks! The nuts holding the faucet on were made of plastic (as most i've seen are) and melted off. So its removable. But removed it looks rather boring....

    I've been considering making an offset bbq using a sink, and you've given me enough to work with. Thanks. A forge is handy too.

    Clever! Sink comes with the fitting for the air hole already, etc. My only thought is that I'd probably go with a steel sink instead of ceramic, but ya gotta use what ya got.
