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.

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!

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!

[@RamboThePyro]

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.

[@Daegul2]

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?

[@CameronDuBeers]

That's pretty neat!

[@robbenjamin3558]

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.

[@ArtMechanicsOnline]

***** 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.

[@lunardust201]

Add some wires mesh or screws as support for the plaster to grab on to for the lid

[@thetrickster9898]

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!

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..

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.

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

[@TheHeadHunter1000]

michael C I didn't make any videos on melting cans. :3 You are welcome though.

[@muskokamike127]

TheHeadHunter1000 oh sorry, I thought you were the poster of the video....anyhow, thanks for the info!

[@SunRabbit]

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.

Ahh, KZbin. 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!

[@electricharmonyac7354]

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.

[@JC-bv6et]

same question

[@121bloodshot]

+Jesse Ancel I'd say 5 minutes or more, but then again it's just a guess.

[@chasegradner1634]

+Jesse Ancel i made one only waited accople days and it didnt cracked but we melted the bottom out.

[@ImGinaMarie]

+Jesse Ancel if you get an answer to your question please let me know! Thanks!

[@drewtoli2353]

[@renecabrera7224]

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.

Where can i get plaster of paris cheap in the UK???, online it's like £29 for 25kg bag

[@jook-000]

[@renee1062]

That itself is pretty cheap. Around a dollar for a kg.

[@faizanshariff3847]

+Jimbo-Kills you could get in a hardware shop!!!

[@jacobpaziuk6011]

+Faizan Shariff do you know if I need the steel bucket or will ant bucket do?

[@faizanshariff3847]

Jacob Paziuk i might insist u to take a steel bucket

[@JabbuGuy]

it's sad to see what kind of videos they are making now : (

[@New_user-hm4ug]

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.

[@thereve]

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...

[@ZorlacSkater]

Does this only work with *plaster of paris* or can i use *plaster of new york* too? PS: You did not explain how to fire it

[@KickBull]

you need plaster of LA

[@hughjanos8620]

ZorlacSkater you don't fire it

[@kyanidjevitamin]

no you can only use plaster of paris because Twins are allready fired out :( (sorry if is not funny but i am not american :)

[@kittenmeow7092]

You don't fire it

[@aeriumsoft]

No, it's plaster of Ittoqqortoormiit. Period.

[@jamessever8936]

what can you use for a crucible that wont break that can melt iron or steal?

[@nickpotter8695]

+James Sever amazon.com has graphite crucibles for good prices

[@vogel6554]

+James Sever Tungsten/Wolframium

[@jamessever8936]

SardinTheo48 nice, yea that would work unless you were some person who wanted to melt tungsten but i doubt anyone out there could even get it hot enough to melt tungsten and has no reason to anyway. Thanks!

[@vogel6554]

James Sever Actually, I was just kidding.

[@vogel6554]

Gobalf After a little research... Ok, wolframium/tungsten has a melting point at 3695 K. Lava has a melting point at 1800 K. Tungsten is almost 100% tougher to melt.

Will beach sand work instead of play sand?

[@xXneonfishXxGaming]

I used masonry sand and it worked

[@JelMain]

Probably. Pick it through, sieve it, and then wash and dry it.

[@oncapintada9790]

it works with concret in the place of plaster of paris, in brasil there is not.

[@oncapintada9790]

?

[@nicholasjohnson1136]

wot

[@CraftingSniper101]

what

[@JelMain]

So don't do it. Either you do as told, or you injure someone. Someone else from there asked a couple of weeks back, it's something like gyps without gesso.

[@toolzasm]

Plaster of Paris é gesso.

[@qorrid5485]

I remember trying to convince my dad to make this, ive since finished elementary and middle school and have an interest in cosplay and armour/weaponry so who knows maybe ill get to make one this summer (bc its just not hot enough here in cali/s) and make some actual metal pieces for my cosplays, I do like recycling as well

[@lukassiupsinskas725]

I was welding my foundry today and after work just go to youtube and find out that King is dead. RIP

[@BSANDY]

i love your videos they're just like watching how its made xD

[@cutepig4212]

can i put the steel wool in the actual plaster mix for the bucket itself to prolong the life of the furnace? I'm planning on building one of these and I have a limited budget and I'd rather spend a little more and build only one over time.

[@jaydude25]

Yes, it will hold together much better and makes it a bit less likely to explode on you if you get big air bubbles

[@cutepig4212]

Ok thanks

[@unclesunbro1577]

@@cutepig4212 put the bucket on something that vibrates pretty hard for the first minute or 2 of the setting time. It helps remove bubbles in the mix. They use a vibrating table when pouring big slabs of concrete so, it should at least help here.

[@fraggeddabloons5679]

Not under $20 anymore, just the sand and plaster of paris was $22 before tax. I'm $90 invested now, I hope it works.

[@JelMain]

Too many makers?

[@silaslegault7984]

ya its a lot more than he said and what a click baiter he is

[@fraggeddabloons5679]

NERF RIVAL studios My total amount invested was close to $150, but I bought a drill too. It works, but it didn't get hot enough to melt anything. I think it might be because I didn't make a lid so the heat is escaping too quickly.

[@suitguy969]

The parts of the materials that are actually used might be under $20, maybe that's what he meant

[@fraggeddabloons5679]

Dankus Memus The two main things are sand and plaster of paris. The two smallest bags were $22 total before tax.

[@roymiller2231]

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

[@MrJdmboy10]

Can this get hot enough to melt brass and copper?

[@JelMain]

Just about. Add more air, perhaps go to propane.

[@bryannoyce]

The charcoal will burn hot enough, but it needs enough air. It also might do a little damage to the smelter lining.

[@LegionStriker]

Maybe, this thing might reach temperatures of about 1,000 Celsius, which is borderline good enough for brass and a little under copper. I recommend using propane instead.

[@bryannoyce]

LegionStriker propane does not burn hotter than charcoal its just easier to mix with air. All metals were melted with charcoal before the 1800's.

[@LegionStriker]

Bryan Noyce In a small setup like this, propane will reach far higher temperatures.
