I Made a BIG Furnace to Melt Metals
Propane furnace made with scrap steel, glass and ceramic wool and refractory cement.
I wanted to reline the coal furnace i made five years back to melt aluminum but the structure was in very bad shape as it has been outside to the elements since I made it. So instead I made a new one that runs on propane with two venturi burners I made recently: • Forge / Furnace Ventur...
This has been very long project to make but definetly worth the time as now melting aluminum is much easier and also cheaper.
The furnace holds a 230mm tall crucible of 180mm in diameter, it should hold 35kg of aluminum.
Insulation from the inside out is composed of: refractory cement, ceramic wool, glass wool.
On the bottom center I inserted a refractory brick to have someting very solid to place the crucible on.
The lid is made just of recfractory cement, it's 58cm in diameter and 5cm thick, so it weights 20kg.

Finally. Seen a video.. stated it’s purpose in title.. showed a great way to DIY said product. No frills no BS. And accomplished this perfection without having to listen to some tool who just loves the sound of his own voice blab on about why he decided to bless us with his idea. Thank you kind sir.
And no annoying music.
Nicely done! I've got a washing-machine barrel that I've been holding onto for a while, now that I've seen how you finished yours I know what I need to do to finish mine!
It is very satisfying to watch something like that being made to suit someone's own needs.
Pro tip: when using concrete and forms put either axle grease or diesel fuel on the forms where you don't want the concrete to stick. Note: colored axle grease will stain concrete.
So a light layer of diesel on the bucket before cementing? Good to know, thank you!
We used to coat metal wall forums with a mixture of kerosene and diesel fuel so the concrete wouldn't stick to em.
Yep, the kerosene/diesel mix is pretty common in construction as a release agent. But really, anything greasy or oily that doesn't evaporate or wick into the concrete (don't used water based stuff) will likely result in success for a DIY project. Just be sure to use something expendable, non-porous, and preferably with a smooth finish that doesn't have an odd shape (like a coke bottle or something), because not even a release agent will work well enough to get some things out...that's where the expendable part comes in LOL
Just use furniture polish, it's convenient and low mess.
@@1TUFZ71 No... He's an idiot. Never use a combustible material at any point during this sort of process.
A year later I watching this again and still am amazed on how well you did this! Most just use wool and call it done you went all the way and did it perfect!
The quality of your work and your creativeness do not cease to amaze me. Your videos are some of the very best on KZhead all categories combined.
OMG your plate to stop the crucible from falling out while pouring is Genius. I have been contemplating this complicated slide arm thing.
That had to be one of the cleanest looking furnaces I've ever seen. Great work.
Absolutely , Wonderful
Unbelievably cool, thank you for sharing this! ...and thanks for not adding disturbing music in the background, it's just perfect like this. Highly appreciate this...
Old blue coat must be deleted before using themostable paint. It's cool crucible furnace. Sorry for my English.
Yeah, I see your point, the old blue paint coating might just turn to ash but hopefully all that insulation he put between it and his furnace center will protect it and the paint on top from turning to ash.
no need to apologize.. and yes, such thermoresistant paints strongly reccomend to remove old paint and even not to use primer coat
im tippin he took that into account...he's no dumb bunny you paint Nazis
@@busybee6889 He plainly didn’t, otherwise he'd have known to remove it. Only the insecure can't cope with constructive criticism, always right non learners
I made this and it ended up perfect all thanks to you! Great build....NOW the disclaimer LOL I installed casters under also like you and when I swung the lid the forge about tipped over from the lids weight, so I installed an axle at the rear. Also I made a 2nd handle mounted to bottom drum so I could steer it vs the movable lid trying to move it around didn't work so well for me. Thanks again!!
Excellent build! I like the use of the venturi burners. No need for a power burner when you're just babysitting the thing until you're ready to pour.
I'm always impressed at how you think in innovative ways to accomplish your goals. Very nice work!
Awesome build, nice incorporated design using your dual gas ventures / burners which work very well. 👍👍👍
Nice - very nice. I left my furnace behind when I moved - it was well weathered. Considering a Devil's Forge, but may make a second from scratch instead. Your video reminds me of the fun it was to make my first one. Single port, forced air injection, charcoal powered - a bit slow, fully functional for aluminum. Yours looks faster, hotter, and perhaps easily copper and brass capable.
Your lid, and the 2 crucible holders you use is by far the least stressful set up I have seen. Well done.
I need to do this.
We made one but smaller..

I've built at least 5 foundries till now. And I can confidently say that I'm about to build the 6th one. Like, holy shit. This is PERFECTION
what type metal that's inside the furnace that's used to heat the other metal, the one that doesn't melt ????
@@jmadventures9830 it's called crucible...it is made of porcelain or any other inert metal which can able to withstand high temperatures..
@@agriculturemachinerychanne9574 thanks I figured it out eventually... did you build a foundry ?
@@jmadventures9830 no
Excellent work, and excellent video showing us only the work and not filled with a bunch of distracting music or narration that wasn't needed. Consider me a fan, if all your videos are like this!
This was one of the most entertaining videos I have ever watched! At first thought you were going to weld the handle that you spin open the lid with. A vibrator underneath the pan you pour the metal in may flatten out the shape at the top to make it smooth before it cools down too much and get the air bubbles out of the metal. I remember in my weld class for one semester we always had the slag on top of the metal and had to tap it with a hammer to break it off. All we did was weld some steel with oxycetaline torch and also weld a tool box we all made with a spot welder. We also got to arc weld a little bit. I was in electronics, but the one semester we had to take a class that involved some welding. That was one of the most enjoyable classes I was glad I took even though it was required for my associate degree in electronics. I loved all the forming you did using plastic and other materials until you got the desired outcome. I could see a 3D printer being used to create plastic molds for you to make other things out of cement as well and being able to remove the plastic.
Your creative potential seems limitless.
I have a commercially produced, industrial grade furnace similar to this and it’s a great design. You can throw an electric blower on it as well and it’ll get your temps higher (mine has one built in). Look forward to seeing what you cast in one this size!
If youre using concrete or motar and you plan to use pipes like he used for the gases, dip the pipes into used motor oil. The oil prevents the concrete/motar from sticking to the pipe. When making sewer lines and manholes, we use 1 part deisel fuel and 3 parts oil for the ladders and holes for various pipes that are mapped into the concrete during pour
Hands down the most impressive and sophisticated home job I've ever seen,
I'm always really impressed that the homemade workshop tools and gadgets always look so professional and neat. Another great video!
Signed Edison.
That's a great idea. I have tried to cut so many things like that. With a wibly wobly cut.
Somebody knows their way around the fabrication shop! One of the best builds I've seen on KZhead in years! 💪👍
Damn, I love people's ingenuity sometimes. That angle grinder on a plywood fixture and using your microwave for the height...genius. lol. Made my day! Great stuff!
I love how he basically used his angle grinder as a can opener xD
I used a jackhammer to cut open 50 gallon drums all the time. I got quite good at it because I had to do it at least once a day at work for two years.
Yeah but I think you had enough
Albeit an expensive can opener.

Good job man! That puts those store bought devil forges to shame! Can't wait to see what you melt in it!
Another rock solid project by my favourite man-bun artiste. Thanks so much!
Amazing work one of the best looking foundry I have seen and incredibly creative to the extreme
I when I was a boy. Melted led in my mothers cooking pan's. Then she cooked my dinner and it. That could explain 🤔 a lot. M
hey, i've always melted lead in my cooking pots, and i've never noticed a proboboboblem... wait, what were we talking about? am i actually typing at the moment? i thought i was at the beach
@@auroraborealis5565 now thats funny!!
That would explain your typing skills
A reminder that ghettos in the us use a lot of lead paint, and lead poisoning has been shown to significantly increase aggression.
@@bacicinvatteneaca the rest of the world banned lead based paint decades before the United States did, because rich people were making money and our law makers thought that was more important than public safty.
I went from looking at a small easy to use electric metal furnace to some guy making his own gigantic one. That escalated quickly!
I've built a couple of forges and a furnace, some with home-made refractory, one with commercial materials. I'd just like to say that I can really appreciate your design and execution😊
Your ingenuity, engineering and execution of these projects is so inspiring! Thanks again!
This is by far the best DIY furnace I have seen yet... and I think it's the one I'm going to try replicate!! Really love the crucible tongs and pourers too!! Great vid thanks :) Edit: also great idea on cutting the drum!!
This is the best diy design ever seen! Can you tell some melting time? It would also be great to have more info about that tongs!
VERY CLEVER! Yes. I am jealous. Your design is functional and so ergonomic. I love it
good job, I found that the dense lining soaks up a huge amount of heat which wouldn't be a problem if ran for an extended period of time. i removed the hard brick and replaced them with soft brick 26's the temp in the furnace went past 2424F (that is max for a K tc) as soon as i sparked it off. it lives outside and is a little over 20 years old. Another thing you may want to keep in mind when building a furnace is the lining will expand and if the shell will not allow this it will crush it's self.
Can I just say that I love the fact that you used a microwave to make that cut at the perfect height 😂
I am really amazed how creative yet simple your designs are Keep it up Ps: big fan of your work 😍😍😍🤩
Apart from him not removing the original blue paint before putting on the high temp coating this is a perfect project. The best yet that I have seen , especially if like me you have a workshop to store a large heavy furnace . I too was contemplating just buying a lightweight one from vevor, but after seeing this I now want to copy it.. Also I have the tools and welding gear, but not much cash to splash as I've just retired. Building my own I can do a bit at a time and build it over a few months instead of having to pay out a big lump of cash to buy the Vevor. Also, this self build is bigger , far more robust and will have a much longer life. Great project, well done ! 😊
I agree because is the best furnace Me encantó su trabajo mi amigo. God Blessed you
What a smart build! I’m in awe 🤩
That's Awesome, BackstackD Castings would be impressed.
Terrific job! I need to make one of these altered to open from the side. I'll have to figure that part out.
Thanks!! I like when people think outside the box and go for it!
I feel so accomplished, and all I had to do was watch this and eat a sandwich. Great work
Super idée je vais testé ca
Simply AMAZING!! Greetings from Salem, Oregon!🌲🌲🌲🌲 Thanks for sharing!
Very nice Furnace, BBP!!! it should serve you along time. Thanks for sharing.
Very good work!!!
Nicely done, sir.
Well, that was awesome to watch and learn about. Cheers man.
I'm currently in welding school and I must say your welds are pretty good!
Awesome build, man!
All that to make cupcakes??? I salute you, sir!
Next time you are making a cast or mould using concrete or cement, cover the mould surface area with a thin layer of grease or thick oil, it will make extracting the mould much easier for you.
Gran trabajo, como todo lo que haces, muchas gracias por compartirlo amigo. Un fuerte abrazo desde España.
Overall, this was a very impressive build. I'd like to see a breakdown of the materials used & the overall cost. Did you think to include temperature sensors & gauge for specific metals, or is this just for aluminium/copper recycling? Also, that pourer handle has to be one of the cleverest methods I've seen to hold & pour with a crucible full of molten metal. Most of the time it's a set of curved tongs that have to be held in an annoyingly awkward way with heavy gloves.
Stick welder! About time some on on KZhead welds like the rest of us savages.
A stick welder can be perform to a very high standard... in the right hands.
I really liked it =) Now I am looking forward for what will come out from that aluminum casting.
Great video and very nice job on the furnace, thank you!
Awesome design! Definitely have to make one now!
Any updated?
cant wait new videos with melting stuff
DIY videos like this are so inspirational. The deep sense of satisfaction and pride in your own handiwork is something money can't buy.
Thank you for showing how to properly and safely use kao wool. Too many videos showing unsealed kao wool being used. Nice build!

Great job, really helpfull if i want to made one, thx again for thoses great videos.
its really good love your vdz from Pakistan
Such a smart design! Did you do this or were the plans available from somewhere?
This design looks robust and strong, but performs very poor on containing and isolating the heat. I would not recommend it.
@@shuvalassaf And what's the reasoning for your assertion here? As at the moment it's entirely baseless.
This is ok if you’re only planning on melting aluminium. I have a foundry made from an oil drum but use it for melting bronze. The problem with this design is there’s not much thermal insulation on the lid. I use a full size oil drum with 7.5cm of ceramic wool then coated in 5cm of refractory cement. I can use an A35 crucible easily with that setup and it only takes 2 hours to melt a full crucible. You’ll just have to work out what you’re going to be melting and work out what temperature you need before making it. I think the size of this is a bit over kill for the size of the crucible. That looks like an A12 maximum which I used to use with a small propane foundry which was only a fraction of that size.
MrPhuct there’s no point spending way more money on map gas if you can do it with propane though. Also I’m really commenting on this being a smart design. It’s more of a waste of the oil drum. There’s way more insulation than is needed on the walls and not enough on the top. Plus it has a chipboard bottom. Even if it doesn’t burn it won’t last very long. If someone was going to make something similar I thing this is a poorly thought out design. You can get so much more out of an ‘oil drum’ foundry. It’s a waste of materials (expensive materials) to make something so big for such a little crucible. To melt that material you have to heat up so much thermal mass it becomes more expensive. For something like an A12 crucible (I assume that what it is from the video) all you need is 2 layers of ceramic wool in a mini oil drum (domestic frying oil drum) otherwise you’re just wasting fuel to heat something up that you’re not going to melt. I have made several oil drum foundries and use them daily and I have had to strike the right balance for fuel efficiency, size of my castings, material and usage costs.
@MrPhuct what do you think about devil forge furnaces, would it be a nice investment over making one of these? Im planning on melting bronze copper aluminum and thats about it
Best effort I have seen. Thanks for posting.
Great keeping the flame at the side to create swirl affect in the furnace, very efficient!
The Better way would be to aim the pipes at a downward angle toward the base of the crucible, and the fire would swirl around the crucible all the way up the crucible sides, and ends up with a more efficient heating pattern. I know it works as I have mine made like that and it gets 10 Pounds of red brass from cold metal to pouring temp in 1/2 an hour. Annnd I am using standard natural Gas.
Is it hot enough to make a crucible steel?
Is there a specific microwave oven that I need to act as a height gauge for the levelling out the cut in the first clip, I really enjoyed watching this video and looking forward to seeing some more of your videos....Phil 🇬🇧
I am amazed you got away with using so much water with the cement.
Thanks for the great video, I need to make this... I think an old metal shopvac might make a good starting point.
