Backyard Furnace - Aluminium

[Spart248]

The idea is to remove the slag, not mix it around more so its harder to get out -.-

[MausTanker]

u forgot to remove the impurities

[guyguy768]

those cupcakes r made just the way i like them

[ThePoliticalToons]

4:14 I was expecting the terminator to rise out of that.

[ZebbMassiv]

how much is a cupcake worth?

[kingmike40]

@ZebbMassiv With the price of aluminum being 3.00/pound about 3/pound.

[inhuman0id]

how toxic are those muffins? and the brownies ... ?

[Artoconnell]

I guess the upside is that hard drive is now gone forever?

[wilbeckj]

you need to scoop the slag off, not just poke at it!

[jekennamer]

stupid noobs

[jchsnathan]

he has enough stuff from his kitchen he should have brought a spoon

[hydrobot2003]

so for 12 cupcakes of aluminum and 1 cake pan... How much do you get paid? Honestly.

[StabOfMyVenom]

Refund for an aluminum can: 5 cents

Value of the aluminum as scrap: 3 cents

[draconite420]

@StabOfMyVenom Calue as aluminum made into bars: 10 cents, logic fail for you

[StabOfMyVenom]

@draconite420 maby in minecraft

[scottiblasto]

@draconite420 what if its about something other than making money... say the thrill of doing something that not everyone else does? Thats worth more than 10 cents to most.

[guitarded715]

ever notice how the aluminium slag smells awful? especially if you quench the newly hardened pieces? the slag usually (depending on what youve melted) has really nasty chemicals inside. if you melt down old pop cans, the paint doesnt all burn off. paint is metal too, just enough to mess up bits of aluminium, for safety sake, id suggest skimming.

[leandeganis]

dont you have to take all that floating stuff apart before? Isn't that scrap?

[leandeganis]

what kind of concrete or what do you use to build that box?

[Savrollo]

what is slag?

[Hamish087]

@Savrollo impurities and crap in the metal, usually rises to the top

[Savrollo]

@Hamish087 thank... I tried to google it but have no fair answer jejejeje

[wilbeckj]

I don't think he knows what slag is

[epicnessinacan1]

Aluminium cupcake come get them wall there hot

[spencerculpepper]

how does the aluminum not bind to the pan when it cools

[humanity6fl9]

i suspect if he's bringing it to the recycler, skimming the slag is a mute point.

[zombieX111222333]

cupcakes of death!

[humnboltsquid]

how did you make the burner assembly? and don't listen to the others..... they are just jealous it heats so fast

[humnboltsquid]

how did you make the burner assembly?

[MrMTurbo]

And........whats the point in this???

[1536mbComedy]

that's a good way to clean your pans out, just incinerate everything on the pan, lol

[210482fmj]

i think perhaps cleaning the metal before melting would eliminate some of the unwanted crap form it. I'm guessing the recycling factories use some kind of acid.

[nekbiodieselworks]

I've never seen cupcakes made that way before

[Tewrobert]

I hope your not breathing that stuff :) Take great care with your lungs ..

Great vid, thanks for sharing,

[stormryder4fr3]

some one needs better protection while pouring.

wleding apron and spats come to mind.

[TheMacason]

Omg why didn't you clean the aluminum first XD

[TheMacason]

:D Rick Roll'd

[UnstoppableSlinky]

What is the box thing made of?

[evangoodlock1]

Is there any point to casting muffin shaped aluminum pucks?

[roksys69]

@evangoodlock1 yes, that way it is easier to store and you have 100% aluminum and no slag in the mix

[NAMTRIP]

Cool,aluminum cup cakes!!

[pyrolynxproductions]

Dude whats the cast your using i'm surprised it won't melt from that hot metal.

[dolzaolcom]

@pyrolynxproductions Aluminium melts at 660.37 °C and steel around 1300ºC.

[bigcoolviking]

sift the slag don't be a drag

[Takiado]

@bigcoolviking haha nice

[frosty9595]

The music makes it all the more exciting..... lol

[xao616]

@nivenheim acctually i ended up just melting the sign whole, the stuff just wound up on top and i got it off.

[brentusman]

do like the dude is sayin' you must get rid of all the slag

or try to add some carbon

[brentusman]

do like the dude is sayin' you must get rid of all the slag

[TheDarkone1111]

Mmmm ! ... Aluminum Muffins !

[anuraganimax]

yummy



[zeedee21]

can you say Dros?

[honeybunchickens]

Is that regular concrete on that box you made

[8hollowtip8]

i like muffins

[MrKaddan]

can the aluminium muffins get shocked by cold water like ice cubes in hot water and crack?

[halo5549]

Aluminium muffins! :P

[junkymagi]

some of the slag is metal that was alloyed with the aluminum to make it harder, leaving some of it in the ingots lets you put some flux in next time you melt to realloy it (and if you're selling the aluminum ingots, makes them weigh more (^_^) )

I've got about a dozen 3.5" hard drives I'm fixing to melt down

already melted down a couple of ~5hp engine heads into ingots :o)

[superMarioClips]

looks like meurcury when you poured it !

[haylspa]

you know you would have more ingot's if you got rid of that slag that crap will make it weaker to if you don't get rid of it, also other then ingot's don't expect it to form well to any molds with that in it. I know you have heard that before but it is alot more easy getting rid of it the first time and you dont have as much waist also please keep in mind it's less work scraping it off then it is try-ing to mix it back in

[noxagol]

I would have just left it to cool as one giant block in the furnace. Once it was fully cooled it would have come straight out because of the shrinkage.

[1546LE]

MMMM warm milk

[panzuman]

those muffins look super tasty

[chooechooe]

a muffin weighs a muffin

[ballygeale1]

that was a great video 5 stars

[starshock01]

idk why but when you where dropping the little muffin casts into the water it made me lol

[Judy1989]

how much it cost per min?

[xao616]

i've got a few questions, correct me if im wrong on anything, but i believe he is pumping propane into the tube thats going into the box, and a reversed vacuum is pumping in oxygen to make it hotter...or not? anyways, what if you use mapp gas, and a bottle of pure oxygen, would that work better? what is the box? concrete? clay...?

and i've acquired some signs in my past (STOP or NO U TURN signs) those are aluminum. how do i get the reflective ... stuff... off it?

[starshock01]

regardless of the fuel if you add more oxygen the reaction will occur faster, and with any kind of residue on aluminum just melt it and the reflective stuff will blacken and turn into a powder that should sink in the crucible

[AidenZero]

hahah thats one way to clean your cookware, dump searing hot liquid metal into it lol

[danieleriver]

what is it the blak material for stamp??

[darksideofthebrick13]

you need to get rid of all that slag

[fedaikn]

@darksideofthebrick13 i guess this one is called dross , slag is a different thing and is usually encountered when melting brass, bronze, silver, gold, and especially iron

[snarfbot]

@darksideofthebrick13 thats not slag, its batter. muffin batter.

[ganjahero85]

heard a story about a guy throwing a pepsi can into a thing of molten aluminum after he was done with it. fucking shit went all over the place, he was working at a place called Mid-South, making water pumps for cars. Guess he picked the wrong day to have a refreshing drink on the job

[junkymagi]

@ganjahero85 hopefully that idiot didn't scar someone

few drops of liquid left will explode into steam and blow molten metal all over

[fosterssucks]

thats T2000's penis in there, and whatever else he wants it to be

[MediaGnome]

i got a question does the unpure 'stuff" stay behind when he pores the liquid into the mold it looks vary clean...also what do they use these aluminum cupcakes for?

[WoWbob396]

that stuff on the top is the dross i believe or AI it stays on the top and always reforms, but it is lighter than the aluminum so it floats and it stays there and so u can pore the liquid out and it will stay in there if u dont pore it too fast

[BasementBen]

WOW!!!

[Th33k]

i dare you to drink it...

[gaarainblood]

lol we are both sick fucks because when I was watching the Vid I thought the same thing

[bornfromground]

haha yea...  times for some shots everyone gather around!

[tjinga2u1]

you are supost to get the slag off but the final product looked fine :/ the aluminum when he pored it the slag didnt go threw the hole pourer thing i have a question what do you do after you make the ignots? i was going to make bars then heat them to make a knife but im conserned it may not be strong enoughf how many pounds can it hold befor it breaks?

[DjinnJuggler]

Aluminum is not good for knives, it's a ton softer than steel(which is what most knives are made of) Unless you want a knife that just looks good and cannot be sharpened, find something besides aluminum. Maybe grind down an old file? There's lots of videos on knife making, just research a bit.

[renderrob]

You gotta skim the crud off of it dude!

[DerekStickley]

ok so my shiny cupcakes and pie JUST came out from the furnace i mean oven so we have to wait a while for them to cool down yummm gots to love grandmas cooking

[kriegdouch]

what was that one piece that was blocking the flame, steel? and how is that torch operated, i don't see any lines going into it, or im missing something

[junkymagi]

Looks like it melts very well to me. For melting large pieces of scrap it's perfect, less work breaking large chunks down to melt. I've got an intake manifold that I'm going to have to break up before I can melt it down into ingots *sigh*

[pyropal000]

I have a couple of questions. What where those molds made of? Cast iron? Won't that melt, since it's iron, and can be melted and poured? Also, what keeps the aluminum from hardening into the mold and not coming out? I'm just starting metal casting, and need help.

[victorfan12]

It looked like a muffin tin

[junkymagi]

Cast iron melts a lot higher than aluminum, no chance molten aluminum will melt steel or cast iron.

[UGLandrum]

OK, invest in a keyboard with a comma key dude, I have simply done the research and been to college, I like to learn about interesting fields in science and industry. My statements are right, know it all's are usually wrong. BTW this guy is flirting with danger, I wouldn't want to be anywhere near that when it shatters.

[fairhit]

whats the thing called that you melted the amilminium in?

Jack.

[steveBB30]

small reverberatory furnace. V good at melting large amounts of aluminium quickly/efficiently but you get more dross (alu oxide, some goes into the casting during the pour), and more gas in the metal

furnance body looks like it was made by filling the gaps between two nesting boxes with a castable refractory. metal strips add strength/form lifting handles. (nice!)

Not a great idea to let the alu solidify inside, as it will expand on cooling/can crack the refractory. Nor to cool with water!

[junkymagi]

Special cement for high temps cast into that shape.

[yourBLOODisonme]

very nice video

[crazyboysofamerica]

and i thot my moms muffins were hard that makes them look like marrshmello

[rivestimento]

Che sarebbero??

[GodofCheos]

the braceted part is for thows of you who did not know what part was the slag

[GodofCheos]

ya ya what ever, what ticks me off hear is that he tryed to remix the slag (the chuncs of stuf that was on top of the aluminum) back into the molten aluminum. slag is the inpuritys that was in the aluminum before meltdown.

[27simber]

what is the pot made of mate

[iZimTehBloxxer]

Mmmmm...Aluminum.....

[JIMex2010]

awesome

liquid metal just like in the terminator 2 movie the bad guy

[death2148]

Oh yea and I wouldn't use cement it will crack and explode at some point ;D

[autograssboy]

what is Alzheimer??

[ryanhall2013]

Welding aluminum is also not a very smart thing to do.......  The yellow vapor is poison.

[UGLandrum]

It is also radioactive, those radioactive isotopes cling to micrscopic particles on iodine on the ash in the smoke and when breathed in they deposit themselves in your thyroid gland, leading cause of radioactive particles entering the body (the thyroid), this can result in premature death, a slow one though (over many years), not sudden. Always wear a respirator and possibly sealed eye protection since many toxins enter the body through your eyes.

[combinatorix]

You're an idiot.

[ryanhall2013]

Actually, I'm a chemical engineer, combinatorix. Certain types of aluminum produce ammonium hydroxide when heated.

[combinatorix]

You're still an idiot, and surely don't know anything about welding. Aluminum is commonly welded safely for thousands of purposes. Structural aluminum welds are commonly done using TIG welding, and while it is not easy, it is plenty safe for a trained individual. Obviously adequate ventilation is needed- as is with ALL types of welding. Besides the need to clear argon, many gases can be formed in the arc (most conspicuously ozone). Aluminum itself however, is not going release poisonous gas

[hatstalker]

Aluminium can be safly welded yes, its just a bitch to weld.

[combinatorix]

I don't even know how you can call yourself a chemical engineer. Ammonium hydroxide? Poisonous yellow vapor? Are you kidding me? Go check out wikipedia or something and educate yourself kid.

[hatstalker]

People i think he was referring to galvanized aluminium giving off Ammonium hydroxide.

[Onetnez]

is it true if you have more then one air scource the flame will be more intense??

[UGLandrum]

Not nessicarily, just have a steady smooth supply of air, with no imperfections on the inside of the blower casing and tubes. You don't want any turbulence until the air reaches the inside of the furnace chamber, then you want a vortex action, that is what is required to get the most efficentcy out of your blower and heating system.

[Morderesh]

to all you you tubers out there doing this smelting aluminum is increadbly stupid and all though it is a good way to get alzhimers

[junkymagi]

so all the people working at factories that produce the millions of aluminum products a year are getting alzhimers?

[ryanhall2013]

Yes, aluminum, freon, and household chemicals and pesticides can all causes Alzheimer disease.If you know that you are at risk for developing Alzheimer disease, you should talk to your doctor about a detoxification program.

[UGLandrum]

Aluminum deposits itself in your blood and cellular structure of your cells, it is a good idea to detoxify yourself every 10 years or so, even if you are not an aluminum welder, even if you cook with aluminum foil.

[UGLandrum]

Your paranoid, all you have to do is exercise some safety mesures and all will be fine. Its public paranoia propiganda, and its melting not smelting, smelting is used to separate the aluminum from the bauxite ore

[yourBLOODisonme]

UGLandrum, you are a tool.

[UGLandrum]

Oh, and how am I a tool? Because I acually know what I'm talking about, because I have the knowledge and research to back my words up. Because I have over 6 years experiance in the welding and metallurgy professions? Fuck you douche bag.

[ShadowCPU]

I still dont get why home-smelter(ers?) dont use ceramic liquid metal filters for slag reduction, they're like .50-$1.00 a piece

[CACBCCCU]

"I'm preempting anyone that would use this video to prove that there was a second gunman on the grassy knoll"

By also positing a yellow sky it seems you've merely highlighted the suggestion that someone apparently used a yellow reflective light bouncer or the like for this and doesn't want to admit it.

[junkymagi]

4:04-4:06, it's also reflecting the forge

why would anyone use a yellow light bouncer? I'm still lost why you think this is anything but someone's recording of making aluminum ingots outside under the sky...

It's obviously done late in the evening where *gasp* the sky does sometimes turn a yellow color

[CACBCCCU]

"It's reflecting the sky, not glowing yellow"

A uniformly yellow sky, eh?

I'm going to leave it at I find you unsurpassably difficult to believe.

[CACBCCCU]

By the way, the smoke coming off those baking tins is probably from burning teflon, which you do not want to be breathing.

[whittleddownbattery]

That's not a crucible, it's a slagbucket... Although the ingots look reasonably pure for what you're doing.

[samking12]

looks cool but why do this ??

[junkymagi]

Melting down scrap aluminum to either sell or to remelt to cast some stuff.

See the slag left in the bottom after the last is poured? That can't be used for home casting. When he remelts those ingots, he'll get a lot less slag and can sandcast new aluminum items.

[ShadowCPU]

Oh who knows these things? Ask the second gunman on the grassy knoll.

[respectbluder]

loool no u can eat nice metel cakes with your tea

[CACBCCCU]

Gotta hand it to the video-maker here, not only did the color-balance shift around, and is there an indication that yellow overhead illumination was used, but there's even a whistling soundtrack added.

[gorillailla202]

wtf is your prob? dude if u think its fake y r u watching and commenting a 1000 times? go outside and get a life

you=suck :D

[Phlatpop]

wow are you retarted or just plain arrogant

[junkymagi]

Why are you posting? This isn't a video effects clip, it's a metal melting clip. Comment on how he melts metal, not on how good or bad his video camera is.

Ever occur to you that since the guy is a metal caster, he may not care about what camera he uses so may have gotten one without caring how well it holds balance?

I could tell what was happening in the melt, which is all I cared about.

Now, if the poster was giving directions on how to film, then you might have some reason to complain.

[CACBCCCU]

I'm looking at it from the standpoint of pre-empting people who'd use this video to make certain false arguments involving the pyrometric optical properties of oxidizing molten aluminum mixtures viewed in daylight outdoors. Point being you can't confuse thermite runoff spills, especially when they're glowing bright yellow in broad daylight, with any molten aluminum mix that is externally heated to some point below 1500 C, yet alone one that needs a well-designed furnace to create.

Problem?

[junkymagi]

0-o

It's reflecting the sky, not glowing yellow, otherwise the edge in the big pan would be yellow too plus the "glow" changes when he's moving over the aluminum.

BTW, I'm preempting anyone that would use this video to prove that there was a second gunman on the grassy knoll... (see what I did there?)

[junkymagi]

BTW, at least HIS camera isn't jerking around *nudge nudge wink wink*

[CACBCCCU]

Compare 2:56 to 3:04, where the video color balance shifts from blue to yellow.

[CACBCCCU]

I notice the color balance constantly shifting around from 2:30 to 4:00 so much that it obviously changes the color of the dirt. That's a very clever way to get a yellow "glow" off the silver aluminum. Post-production-stage video effects are cheaper than stage lighting, so I'll guess the color-shifting is done post-production-stage.

[Coatul]

You can clearly see the tree's in the reflection, without a light or post in the way at 4:18.

[steveBB30]

Digi Cameras sometimes do that when exposed to large amounts of Infra red, they pick it up differently than the human eye does, and assosiate it was a visable colour. It's especally noticeable if the camera is set to automatic exposure/colour ballance, and then can't decide if the scene is lit by daylight/incandecent light, or flurescent tubes. None that I know have a "foundry work" setting

[CACBCCCU]

"Just one of the projects I've played at at one stage."

I noticed you do stage lighting. Nice yellow overhead light panels used at 4:11 here, anyway.

Now I guess I'll just be waiting for an alleged trump. Shouldn't take long.

[CACBCCCU]

The metal glows red at 2:07 in this.

"Asd for what we are trying to show.. Just one of the projects I've played at at one stage."

I guess this means that it is a good time these days to "play" at aluminum-vaporizing "projects."

[mormanman13]

you need to add some Borax to get those impurities out. Its sucks up those lumps and you just strain them out and you get high grade Al.

[redflame2000]

ALUMINUM MUFFINS!

[ivanov3000mltk]

Can you explain more detailed construction of the gas burner. I guess it is injection type? What is hole diameter, gas pressure etc.

[48EDGE84]

what a fool, why are you stirring the molten aluminum? All that's going to do is gas up you're aluminum. Just scrape the dross, and don't stir.

[ElectraFlarefire]

Lemme see..

The furnace is made of cement, silica sand, perlite and fireclay.. I'm melting down aluminium hard drives and other scrap metal before casting them into ingots for a later project.

The furnace is burning LPG and we know it can get up to tempreatures in excess of 1000 degrees C because we have melted(and destroyed) brass in it on a previous occasion.

Asd for what we are trying to show.. Just one of the projects I've played at at one stage.

[tTatmosT]

it's a GAS FURNACE it doesn't melt concrete... wait, concrete doesn't even melt!

[Schneelocke]

Interesting - but something tells me I shouldn't try this at home. c.c
