WARNING:
Charcoal foundries can reach temperatures in excess of 1,000ºC, which is well above the melting point of hobbyists. This project should only be attempted with adequate knowledge and training, proper protective safety gear, and in a fire resistant area with adequate ventilation. The sparks flying from the foundry can ignite fires, and the fumes from burning dross can be toxic. Use caution and common sense. Use of this video content is at your own risk.

Project Inspired By:
This foundry is an original design, which comes after months of experimenting, and over 10 different prototypes. The functionality is founded on ideas I collected while searching the internet for different furnace designs.
Project History & More Info:
For this project I experimented with 10 different prototypes, to develop a reusable backyard foundry that melts aluminum soda cans easily and safely. I tested different refractory recipes, different containers, different setting for blowing air, and different types of makeshift crucibles.
I tried various ratios of portland cement, sand, perlite, plaster of paris, water, and even kitty litter. For containers, I experimented with clay pots, plastic buckets, no container, cinderblocks, and a galvanized steel pail.
I ended up favoring the galvanized steel pail, and a mix of 50% plaster of paris, and 50% play sand, by volume, which was inspired by a video by NightHawkInLight "How to Make a Soup Can Forge" bit.ly/IBSoupCa...
Depending on where you get, or find, your materials the cost can range anywhere from $5-$25 per unit. With the materials I used, I was able to make 2 units for under $40 ($20 each). Even on the high end, this is probably one of the cheapest, reliable, backyard foundries that can be made.
I used mine to melt soda cans, and extract the aluminum for future metal casting projects. All the soda cans came from a local recycling depot. I bought back 30 lbs from the depot to avoid having to drink gallons and gallons of soda. :) I stored the ingots in various forms, which you can see in the video"Melting Cans With The Mini Metal Foundry" goo.gl/pTP1uG
The technique for making the sword in that video, and the gun in this video is called "Lost Foam Casting" and will be demonstrated in a future project video.

This, this is the TH-cam I miss.
I agree.😌
Same
Same, and now TH-cam is just cheap clicks instead of great vids like this
Yeah...
me too
All these years later and i still remember all the steps as he lists them off, i always wanted to make this but never did cause i was like 12, but i will always remember him and his projects, he will always be the true King Of Random
So did you make it? Its never too late
I made it years ago and it lasts for 5 melts max. nostalgic, but not practical.
@@Kamal_AL-Hinai even with steel wool? he said in another video that it would last 10 times longer if you use that
i used to watch him as a kid too, i literally just made this waiting for everything to dry up rest in peace the legend himself 🙏
Being 12 hasn’t stopped me.
First video I watched of you RIP legend
Rest in peace
Same sad he’s gone
Yaruela same

Absolute legend
It's incredible how this video just popped up in my recommendations after all these years. I remember watching it when it first came out, and it inspired me to want to build something similar with my dad. Your influence on the whole DIY community on TH-cam was truly amazing. Rest in peace, man.
He truly made my childhood entertaining. Rest in peace
True. This man had an nevereding curiosity and left an massive impact on youtube. His DIY videos were unlike any other.
Is this fella still around?
@@DavidWilliams-wr4wb he passed away from a paragliding accident years ago 😢
legend passing @@huanlecongquoc957
Hundreds of you have been asking for the tutorial, and here it is as promised. I'm still using mine frequently and must have melted thousands of soda cans by now :) Some people are asking for a tutorial on how to make the sword, so I'm putting that one on the list for the near future ;)
Thanks for the great tutorials Grant! One of the best channels on TH-cam!
Grant can you make a video using the microwave mental melter? Cheers
I've been waiting so long for this. Tank you!
how do you depreasurize the extinginguisher
***** just activate it until the pressure meter go to the end of the red mark!
One of my favorite videos. My condolences go out to his wife and kids. Rest in Peace man.
What happened to him?
@@TurboWorldHe passed away in 2019 from a gliding accident
@@digitalcthulhu143 oh man, that is terrible. Prayers to the ones he left behind.
Such a sad thing !!!
I'm watching this for about the tenth time but this time i'm siting next to all the materials ready to make this forge Finally !!!!
how much did it cost you total? he says less than $20 but everything he has listed is over $100
I think that $20 figure was just for the Plaster and Sand - which I found to be accurate :)
I just picked up plaster of pairis and play sand at home Depot, about $25... But he was only talking about those, not the bucket or anything else....
@burnt Rubber yeah, and I can't recall off the top of my head, but aluminum melts around or just above 1200°... I build a similar one, and with the slow burning bbq charcoal, it will still melt it, but I tried some straight coal, burns a lot hotter.
@burnt Rubber and the movement of air over the ember's makes it hotter too
Still breaks my heart every time I'm forced to remember 💔. It might sound cheesy but I doubt he ever realized just how much his simple, entertaining, and exciting videos worked to inspire the next generation of scientific minds by showing them how ANYONE with a bit of time, effort, and willingness to learn can use ordinary stuff around the house to make something extraordinary and useful
Just made one today, all this afternoon. While the cost of everything was actually like $100 for me since I was completely unprepared tool-wise, it worked amazingly and was surprisingly easy to make :)
I first watched this video five years ago. Wow. That’s hard to believe. I’ve watched it dozens of times since then and I have finally made it. Grant you’ve been gone for a while now and my love goes out to you wherever you’ve found yourself in this stage of existence.
Love it. Made it. Works!!!!!! I did not bother with the pvc and just connected a hair dryer to the metal tube. I used the exact same measurements, you nailed it! Everyone who wants to repeat your success and has ZERO experience needs to follow your steps. I used a concrete mixer attachment on my drill and the mix came out great and gave me more time to form it before it set. Awesome video!
Careful your hairdryer dosnt get too hot. The pipe also helps keep your skin away from the hot pipe
+gamesdisk thanks for the tip. FLIR camera shows pipe at ambient next to the hair dryer and cool until insertion to kiln.
+meabn007 the pvc pipe is act like an isolator, so you better use it before your hairdryer turn off in the middle of working
+Primayoga Hogantara I find your lack of physics disturbing
meabn007 well according to my experience in the last couple of months that's what happen to me. but if you find it as a lack of physics maybe i'll read my book again. Thanks
One of the first videos I ever watched, it is with immense dismay and sorrow that I say goodbye to this absolute legend, but I will leave you with one of my favorite quotes; "don't cry because it's over. Smile because it happened." -Dr Seuss
You guys have truly inspired me to start a hobby. I build my own foundry yesterday using the steel wool to reinforce. I melted down some scrap cans and other aluminium tonight to cast my first muffin ingots. This thing is a blast.
Has your hobby taken you much further, 3 years later?
@StrangeChickandPuppo yes. I have upgraded to a manufactured foundry and am now experimenting with making alloys like Nordic Gold.
@@mikenash1020does this crucible have many limitations to what it can smelt?
First video I watched from him and actually made this with my dad.. rip brotha
F
After several years of procrastinating i finally got around to making this yesterday. I picked up a leaf blower for 10$ and used an old propane canister for my crucible. The leaf blower ended up being way too powerful so i rigged up a dimmer switch to an extension cord to tone it down some. Works awesome, love the tutorials, keep the videos coming.
Great project.
Ye
Just had to find this video and watch it one more time. Rest In Peace man. You really did change the diy community forever. Long live your legacy.
Imagine his 3 boys, they will forever be without a father. They loved him so much, imagine how they are feeling right now.
Still so sad by your passing. Your content was amazing, your personality was kind, and your legacy will never be forgotten. Thank you for years of quality content and fun 💙
Awesome!
The way that you formed the plaster and sand lining was a really good idea and i love the addition of the lid!
I need to make a new forge and my 5kg bucket of plaster of pairs arrived from ebay today!
Cant wait to give this a go once the weather gets better.
Also I don't know about your forge but after using mine it always stinks of sulfur. couldn't possibly use it as a plant pot!
The Art of Weapons The sulfuric smell comes from the plaster of paris as it decomposes and is heated to very high temperatures. I am not sure the exact temperature that it begins giving off the sulfuric smell though. For this reason, many people try to avoid using it as a refractory material and use a Portland cement, sand, and Fireclay mixture, which is more expensive, so there's a trade-off.
Hi the art of weapons (probably not your real name) I have been watching your videos for a while and me and my friend have made some slingshots from your tutorials and I just wanted to say that you are really good and keep it up
5 years ago.
Long live the king of random. Rest In Peace
Huh i get it long live the king

RIP
Awesome, Grant! Thanks for the detailed tutorial!
Oh man this weekend is going to be fun!!!
HOLY CRAP!!!.. Hi Brian.
kill1 Hi.
Brian cox Should have made it clear Hi Brian Brushwood.. lol.. But good on you
Lol ii knew u where subbed to this channel
Please tell me this comment has nothing to do with the video...
RIP to this man. I’m doing this project this week so I thank him for the great idea.
I took on this project today! It was a lot of work, but I was able to do it on the second try. My one suggestion is to pour the sand in the mixing bucket first, and then pour the Plaster of Paris. I had a lot of trouble evenly mixing the two ingredients when I did it the opposite way, and it ended up solidifying in the mixing pot before I could pour it. Overall, it was a lot of fun, and I look forward to using it. Thank you!
Robert Lewis water temperature plays a role also I accidentally use cold water for my frigerator and it took a lot longer than when I use warm sink water
It took longer to mix with cold water or to dry?
to dry
It's all about the chemistry.... Heat/energy affects stuff...

Why now
Does the mixture need to be exact? When I did it it never fully set and stayed damp.
Please let me know if you took any precautions with that galvanized steel bucket - the fumes I'm talking about. I wish to do this very same foundry but can only find galvanized steel such as in your post.
what do you uese for the blower
Did you have problems with the fire extinguisher crucible? I was planning on using one. My other option is to use a significantly thicker steel cup I made at work.
This was one of the first videos of his I ever watched. Now I’m watching it again, next to the stuff to build it.
First thing I ever made from his videos. Rest easy legend
What happened?
@@seth8128 he sadly passed away in a paragliding accident
Thank you, Grant! A couple of friends and I decided to create your metal foundry, and it worked out great!

SNEAK 100
Lol
**flowers catch fire**
@@Sharknoob21 at those temps yeah I let mine sit out at least for a while because at those temps you can't just pour water on them.
"Son, why is that flower leaking molten aluminum and smoking?"
@@ri5ux435 It's smoking because it looks cool to smoke and all the mini foundries are doing it.
make video about how to make the sand molds
he´s doing it i guess
Its actually really easy just use the thick foam the comes in packages and shape it into what you want to mold then bury it in the sand a few inches from the top
Lyrik Tech dont spoil it for them
i guess im not sure^^"
Lyrik Tech
yep, the mold evaporates when the metal is poured and takes it's place, and voila! The cast is formed
Rip, my friend you were the inspiration of many
Thank you for this very well done series. I used the foundry to reproduce a brass antique drawer pull. Many thanks.
Me and my brother watched this video and were completely blown away 3 years ago. R.I.P. you're an absolute legend
Just saw this great piece for the first time and wanted to respond only to be slapped in the face with this sad story of the demise of this gem. Rest in Peace great teacher. My heart is weighed down by this...
2:55 so gently pry the bucket
Proceeds to destroy the bucket vigorously
I just did it and it worked perfectly
I like these old types of videos better where he just kinda narrates
Way better than nates. Its just clickbate
Agreed
One of my favorite videos he made. He was so passionate about it.
One of my favorite videos from you rip
Thank you so much for this. I’ve just melted my first aluminum cans
Great project Grant!
Thank you great idea for my simple homestead.
Thank you Dan, the man!
Grant Thompson - "The King of Random" how did you de-pressurize the extinguisher
Grant Thompson - "The King of Random" can you name other metals that it works with?
Any idea how hot it gets?? I'm looking to make something that melts gold...
Finally made this yesterday. Used different refractory mix and a proper crucible but it worked great!
Thank You! You got me an A in my Sculpture class this semester for melting aluminum by myself :) Bc my instructor is ONLY impressed by metals! :) haha
And now he’s gone....................
He isn’t dead he just in a better work shop
I love the way you think on all your projects. You have opened my mind on EVERYTHING you do. WOW you have the best channel on you tube by far! Thank you and keep them coming. P.S made my own little BBQ out of a monster soda can. My friends were amazed how well it cooked.
I have to agree, Grant has amazing projects he truly the King of Random. Please keep them coming.
I just made this mini metal forge thanks to the king of randoms video!!! I just need to get a fire extinguisher for the crucible and a bag of briquettes. It costed me about $85 CDN for everything (I had the play sand and hole saws already) can't wait to cast Thor's Storm breaker when it's all ready!!!
My son and I built a foundry last month, and he insisted on trying it out one afternoon when the temperature was in the 20s. Needless to say, although it seemed to be eating the cans, no liquid aluminum could be seen. When we finally gave up, the contents of the crucible solidified quickly, and stuck.
We tried it again today, with the temps in the 60s, and it worked like a charm! The crucible heated up, and we kept tapping on the metal in it until finally the rebar went right through the slag and into the now melted aluminum. We spent several hours melting cans, and creating little "muffin" ingots, doing three pours and emptying the foundry for new charcoal between each one.
The only problem we ran into is we've now lost two lids. Both days, after we let the foundry and lid cool down, when we picked up the lid, it broke into three large pieces, each of which was dry and crumbly. My only guess is that we didn't allow the lids to cure long enough before using them... any ideas?
That's pretty neat!
plaster and sand are not going to hold up for long. Ceramic fiberboard from a pottery supply with a hole cut in the top would be better.
this is a great tutorial and fun project but a part like the lid will not last for many firings.
***** I had this problem once in school using plaster and sand as a mold. It happened to the whole class. Even after being very dry (kiln dry) the structure broke down and my aluminum flashed out of the cavity creating a bad casting. The mold got crumbly too. I seem to remember it being a problem with the sand. You might try a higher ratio of plaster, maybe even 100% plaster. You could try adding glass or wire mesh to the mix too. I'm not sure if it will work but it is worth a try.
Add some wires mesh or screws as support for the plaster to grab on to for the lid
I did it too but, with a metal bucket inside. At first I thought I screwed up, but I was very mistaken. I got to the temperature which it was needed to melt cans it worked very well. All the heat was kept inside, and was easier to maintain the temperature. Now for the lid, if you have any ceramic lids that might fit, that's good, or when curing the lid in the midst of curing the lid add more liquid. I don't know if it will work but try!
I have found that the fire extinguisher used in the video is extremely hard to come by. As a fellow engineer, I have found that a small acetylene torch tank will work.
Thanks!
Thank you
I was just thinking about the empty mapp gas tank sitting in the garage when I read your comment
Hey +James sorensen just use a steel flask which is from $1 - 10
make sure its empty first ;)
I made this 3 years ago. Great memories. May he Rest In Peace.
Hi,did the plaster crack at the time passes?
@@ridgidmaster9291 yes that’s bound to happen especially if u leave it in the rain or cold
@@ridgidmaster9291 from my experience at least
This video changed my life. New lifetime hobby. RIP Your Majesty
Going to the hardware store rite now to build my own and use my 3d printer to make molds for things to make from aluminium.
Thanks for sharing and as always Keep Building👍
doesnt the filament melt?
@@elijahlowe5254 that's how the molds Are made, the filiment burns away leaving a cavity for the metal.
Long live the King. RIP. May his legacy live on.
We loved your video! You made it seems sensible and easy. We were delighted to give this a go and we learned a great deal....Molten aluminium is actually very hot. Really. Molten metal poured onto concrete does this interesting "pop" thing that makes you think that safety glasses might have been a really good idea. Also, I am surprised and delighted to discover that I can teleport short distances. Not all fire extinguishers are made of steel.. Crucibles made out of aluminium don't work as well as one might like. Smoke rises and can come out the back of your hair dryer...
+Karen Pasqualucci Not sure what this comment is supposed to say overall but it was fun to read...
you forgot to use a magnet
+Karen Pasqualucci don't worry the molten metal will definitely burn through your glasses
Just finished testing mine out I didn’t use the same steel bucket and ran into some ventilation issues but it works ok now I’m ready to start casting
This is my favorite ever and got me in to metal work thank you for inspiring me
l missed you buddy ....
same..

Hey everyone, for those who are having troubles finding the "true cost", I had just bought all of the supplies to just make the foundry ALONE. Here is my list and the cost:
10 quart steel bucket - 9.88
1" pvc elbow - .98
2 U-bolt - 3.22
1" 2ft pvc pipe - 2.16
1" 10in. steel nipple(steel pipe) - 5.03
25lb plaster of paris - 10.98
premium play sand - 4.15
total cost: 39.45
Hope this helps!
I made this years ago, and just a few months ago I finally got a devil furnace but I still use both of them equally since this was my favorite project he ever did and he is the main reason I got into metal recycling at all.
Rest in peace king. The king may be gone, but the kingdom will live forever
Best tutorial for foundries so far, even if the measuring units are a bit confusing to me.
Very true, but see mine
it's sad to see what kind of videos they are making now : (

So I leaned a valuable lesson when making mine I used a metal bucket to create the hole in mine took 3 hours to get it out. Still use it today thought I would pass the message on make sure you use a plastic bucket
😂 sorry Jacob, I know it wasn’t meant to be funny...it just made me giggle...I’ll make sure I go with plastic 👍👍🥂
Guys if you dont have an old empty fire extinguisher just set your house on fire as an excuse to empty one ! :)
Good advice I tried it. Now what do I do when it's out but my house is still on fire. ;)
I Cant Think Of A Name
idk i had the same problem :\
+CrazyMarkSRB lol
+CrazyMarkSRB Call firemen... and tell them not to throw away empty extinguishers!

I’m still sad to this day Rest In Paradise legend
I made this when I was 13 just a couple years after the video is made, and he got me into his videos i’m now 21 and still have it
Hey Mr. Thompson and everyone, just wanted to warn you all that eye protection is a must when using the foundry, in addition to gloves, and anything else, etc. And also, DO NOT drop in a can that is closed. I tried melting an aluminum soda bottle, and the lid was on it. It blew up due to the gasses trapped inside of the closed bottle, that when heated up, expand, thus causing the explosion. I got molten aluminum on my face and neck. Thank the LORD none got in my eyes. Even though I was just wearing regular eyeglasses, I still could've gone blind. There are marks where the aluminum melted some of the plastic lens.
lol, yeah
Ahh, TH-cam. You can learn many things here. How to make a gummy bottle, how to fix your phone, and how to make lava in your backyard!

Who else is watching in 2023
2024 lol 😂
I'm totally building one of those
Yusuf Reyes I can't wait till I'm older to do this my dad wont let me do I didn't ask but I know he wouldn't let me P.S. I'm using my dads account and I'm a girl
Michael Lukowicz i have the same problem only i am using my own account
me to im not using my acount
Yusuf Reyes it's not as easy as he makes it seem. You will be at least 100 dollars into it by the time you finish
100 dollars for sand bucket and mix? I don't think so
Mind Blowing Project👏😎
i love your videos they're just like watching how its made xD
For those shopping for the materials, Home Depot has a 2.5qt "mixing container" for about 3 bucks that LOOKS like it might work in place of the $11 2.5 qt bucket recommended in the doobly doo. I haven't built mine yet to confirm...
Rip Man U will be missed
My dad and I are building on right now. Thank you
like many this was the first vid i saw. I couldnt believe the news when I heard it. Rest easy.
uhhh I've built a literal dozen of these (one small one for myself then a bigger one since it went so well)
and then i had to make mini foundries for all my friends!!

ratio for plaster, sand and water is for every 7 cups of plaster and sand you'll need 5 cups of water.

Old king of random: how to make a homemade metal foundry to melt metal
New king of random: what happens when you pour water into a cup?
Did you watch his "how to make dry ice" video?
What can I use if don't have an extinguisher?
You should have one anyway doing this kind of work, so buy two, use one so you know how the other one works if ever you need it, and then you've got one to recycle on this.
buy a discharged fire extinguisher
just buy a regular crucible for like $10
true
thanks
WARNING: This does NOT cost 20$. Try 100.
if you make more then one of them they tend to cost less
I made calculations, still about 60$ per thing if you make a ton.
Cost of used fire extinguisher: Free.. Cost of plastic bucket: $2 at dollar store.. it all really depends on if you know how to get stuff cheaper (or free)
Have you actually made this foundry? I tried making it, the cheapest way possible, and it costs at least 60$.
*****
i made it, sand+plaster cost $10 for enough to make 4 of these things. $5 for the steel bucket, i found a steel pipe for air at the scrapyard
Miss you man
