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
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.
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 ;)
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
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!
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
@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.
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.
Just made one today, all this afternoon. While the cost of everything was actually like $100 for me since I was completely unprepared tool-wise, it worked amazingly and was surprisingly easy to make :)
Please let me know if you took any precautions with that galvanized steel bucket - the fumes I'm talking about. I wish to do this very same foundry but can only find galvanized steel such as in your post.
Did you have problems with the fire extinguisher crucible? I was planning on using one. My other option is to use a significantly thicker steel cup I made at work.
One of the first videos I ever watched, it is with immense dismay and sorrow that I say goodbye to this absolute legend, but I will leave you with one of my favorite quotes; "don't cry because it's over. Smile because it happened." -Dr Seuss
After several years of procrastinating i finally got around to making this yesterday. I picked up a leaf blower for 10$ 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.
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.
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 💙
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
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
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...
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?
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.
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 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.
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!
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
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.
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👍
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!!!
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...
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.
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.
Here are the prices for everything you'll need to make this. Please like this comment so other people can see. The Mini Metal Foundry Plaster of Paris - 15.98 1. Sand - $3.77 1” X 12” Steel Pipe - $7.13 1” PVC coupling [FLPT x Slip] (one threaded side one slip) - $3.14 1” PVC Pipe (2 ft length) - $2.89 4” U-Bolts - 1.27 x2 = 2.54 Steel bucket - $9.88 Small bucket - $2.35 5 Quart Big Mouth Bucket - $13.07 Final Price $58.35
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
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...
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
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!!
Nice Work. This reminds me of my Foundry course in secondary High School 1972. I did too similar thing you do. I remember molding coins and placing it in the JUXE- BOX, when it stacked-up in the coin slot inside the music machine, we were free to select and play any songs freely the whole night until the owner noticed that there's something wrong in their music machine.
Very informative , however i have one question. approximately how long should we wait for it to cure before cranking up the heat? To keep it from cracking due to excessive moister in the plaster.
TheHeadHunter1000 thanks, I just watched your video melting cans and saw the hair dryer! I had one, but when I went bald, the hair dryer went too lol......I never should have gotten rid of it, I've needed it for many things, none of which involve drying hair hahahha
michael C For doing aluminium you can use regular coal, or charcoal briquettes. If your setup is large enough you can just use wood. You don't need any other fuel source, just a lot of air. This can come from a reversed shop-vac type vacuum cleaner. Just that if you're gonna use wood, you'll have to keep adding a lot of it very frequently, so it's best to use hard wood like oak, elm, or hickory. Don't bother with pine or birch. The more air you put into it, the faster the wood (or coal) will burn, but also will reach a much higher temperature than say in a campfire or a fireplace. Also, when you drill the hole for the steel inlet tuyere, you want to angle it a bit to the side so that when the air comes in, it goes around the perimeter like a vortex. If you use coke in place of coal, your temperatures will skyrocket to the point where you can easily melt steel provided that you have a constant supply of pressurised air coming in, and a suitable ceramic crucible to contain it. I apprenticed in metallurgy for 2 years and since I've done all this, I'd recommend you get an electric furnace because those are the cleanest and easiest to use. And PLEASE watch videos on how to use these safely because if, for instance you're adding say Silver to an already molten mass, and you're not careful, you could end up with a face full of molten metal, same thing with pouring into an improperly cured mould. DO invest in all the safety equipment like gloves, goggles, face mask, the proper tongs, etc.
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.
+Chris Austin If you don't have one, you could spend about $15 for a real crucible made of graphite on ebay. You won't have to worry about a steel makeshift crucible melting on you being an additional bonus.

how much did it cost you total? he says less than $20 but everything he has listed is over $100

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....

i guess im not sure^^"

yep, the mold evaporates when the metal is poured and takes it's place, and voila! The cast is formed

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
Best tutorial for foundries so far, even if the measuring units are a bit confusing to me.
Very true, but see mine
Long live the King. RIP. May his legacy live on.
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.
Heroes get remembered, but legends never die.
Rest in peace King.
This is my favorite ever and got me in to metal work thank you for inspiring me
Rest in peace king. The king may be gone, but the kingdom will live forever
This video changed my life. New lifetime hobby. RIP Your Majesty
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

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 👍👍🥂
the only real king of random
RIP the legend. I hope the hardware store in heaven likes you just as much as your local one did.
i love this video so much and i am just finding out about his death and now im really sad and heartbroken
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...
VERY USEFUL WHO DOESN'T NEED A METAL FOUNDRY
I love this so much I use it for blacksmithing
So easy it is to make my buds love it
+Silver boy gay

+Lost In Space Electronics how is that gay?
+Lost In Space Electronics I think he was referring to his kids.
I’m still sad to this day Rest In Paradise legend
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!
Will be making this over the summer. Fly high brother man ❤
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
people from other counties be like: wtf is a 2.5 quart bucket
+indivisual Aka me ;_;
Hikatzura yea... litres is much easier
+indivisual Not for us 'muricans, we're just used to the imperial system.
+GamingTV You should get used to the metric system then
+indivisual you just said it was easier...?
i love your videos they're just like watching how its made xD
This man's videos are the best thank you !! Wow blown away with the awesomeness
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!
+CrazyMarkSRB thats what I did
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!!
What does the tube that sticks out the side do
l missed you buddy ....
same..
Same
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
Rip Man U will be missed
like many this was the first vid i saw. I couldnt believe the news when I heard it. Rest easy.
I cried the entire time while rewatching the first project I did of his. 😖😢😭
Nice Work.
This reminds me of my Foundry course in secondary High School 1972.
I did too similar thing you do. I remember molding coins and placing it in the JUXE- BOX, when it stacked-up in the coin slot inside the music machine, we were free to select and play any songs freely the whole night until the owner noticed that there's something wrong in their music machine.
2:42 Is that like the Crucible in destiny?
Nah the crucible in this case is just the part were the metals being melted are being held :P
ElementalNinja I was kidding lol
+Stopmo Kole oh ok lol xP
+Stopmo Kole it's actually like Arthur Miller's The Crucible, the classic play/movie about the salem witch hunt
+Stopmo Kole it's actually like Arthur Miller's The Crucible, the classic play/movie about the salem witch hunt
ratio for plaster, sand and water is for every 7 cups of plaster and sand you'll need 5 cups of water.
Does this get hot enough to melt copper? Hadn't seen anything in the comments section saying yes or no.
+AaronClarey : It can melt copper! Da da da it's a Furnace.
+AaronClarey It sure does. th-cam.com/video/kS949QQDtWQ/w-d-xo.html
+Grant Thompson - "The King of Random" You used propane with it. Can i melt copper with coals?
+Unknown Guy The crucible can't be made of plaster, plaster insulates heat and your crucible needs to transfer heat.
+Unknown Guy brobalby not cuz the bowl its in is steel or iron
Your videos were the best and brought entertainment to me in my free time R.I.P
Very informative , however i have one question. approximately how long should we wait for it to cure before cranking up the heat? To keep it from cracking due to excessive moister in the plaster.
same question
+Jesse Ancel I'd say 5 minutes or more, but then again it's just a guess.
+Jesse Ancel i made one only waited accople days and it didnt cracked but we melted the bottom out.
+Jesse Ancel if you get an answer to your question please let me know! Thanks!
+Jappleng University so trying to use this to melt copper is a bad idea?
Did I miss something? What are you using for fuel and a blower?
michael C Charcoal and a used 3$ hair dryer attached to pvc, a size converter, and steel piping.
TheHeadHunter1000 thanks, I just watched your video melting cans and saw the hair dryer! I had one, but when I went bald, the hair dryer went too lol......I never should have gotten rid of it, I've needed it for many things, none of which involve drying hair hahahha
michael C
I didn't make any videos on melting cans. :3 You are welcome though.
TheHeadHunter1000 oh sorry, I thought you were the poster of the video....anyhow, thanks for the info!
michael C For doing aluminium you can use regular coal, or charcoal briquettes. If your setup is large enough you can just use wood. You don't need any other fuel source, just a lot of air. This can come from a reversed shop-vac type vacuum cleaner. Just that if you're gonna use wood, you'll have to keep adding a lot of it very frequently, so it's best to use hard wood like oak, elm, or hickory. Don't bother with pine or birch. The more air you put into it, the faster the wood (or coal) will burn, but also will reach a much higher temperature than say in a campfire or a fireplace. Also, when you drill the hole for the steel inlet tuyere, you want to angle it a bit to the side so that when the air comes in, it goes around the perimeter like a vortex. If you use coke in place of coal, your temperatures will skyrocket to the point where you can easily melt steel provided that you have a constant supply of pressurised air coming in, and a suitable ceramic crucible to contain it.
I apprenticed in metallurgy for 2 years and since I've done all this, I'd recommend you get an electric furnace because those are the cleanest and easiest to use. And PLEASE watch videos on how to use these safely because if, for instance you're adding say Silver to an already molten mass, and you're not careful, you could end up with a face full of molten metal, same thing with pouring into an improperly cured mould. DO invest in all the safety equipment like gloves, goggles, face mask, the proper tongs, etc.
0:04 “the decorative flower pot is cake”
man I miss this legend he made my childhood
Same now it’s run buy two high school drop outs
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
Where can I get an empty fire extinguisher?
+Chris Austin City dump/landfill, or maybe at a scrap metal recycling operation. You could call them to see if they have any.
old used up blue propane torch bottles should also work.. just MAKE SURE they are empty so you don't blow your hands off.
Try a fire extinguisher service company. They do take them out of service if they can be refilled.
+Chris Austin If you don't have one, you could spend about $15 for a real crucible made of graphite on ebay. You won't have to worry about a steel makeshift crucible melting on you being an additional bonus.
+DailyAverageGamer what size do I get? I'm not seeing exact diameter sizes just labeled by number
Now I can forge battleaxes in my backyard
Teeny tiny battleaxes.
It won’t be strong but it will be stronger then wood
Thanks!
