How to Make a Free Aluminium Melting Furnace

Make an aluminium melting furnace for free using a paint can as the furnace and a tin can as the crucible. With wood as the fuel it is capable of melting aluminium at home, completely free.

This cheap metal melting furnace (often called a foundry), will allow you to melt and cast aluminium at home.

I've seen so many videos on DIY aluminium melting that claim to be cheap and easy, but all of them require something like heavy insulation foam or a gas tank for fuel.
This is something I could just go to my local park and do with maybe ten minutes of rummaging in my rubbish bin beforehand.
Absolutely brilliant, cheers lad.

Pretty interesting, my suggestion would be to fill the can with water and freeze it so that the can does not de-form when drilled.

On the TV show "Friends", Phoebe had a brother. She wanted to get to know him better. She asked him what things he likes. He said, "I like things that melt." Feeling a little uncomfortable, she then asked him what he didn't like. He said, "I don't like things that don't melt."😂

The first 30 seconds of this video are more informative than the rest I've seen. thank you.

as a complete newcomer to this type of thing, im really looking forward to trying out my first, and free furnace 😍

Here’s a tip for ppl using wood… as time goes the high temperature will turn it into charcoal before it completely burns I did a test and the temp was basically the same maybe a 20degree difference

Thanks for the video because a lot of the others are hard to get products but these are all at home products

You never said what you used for your casting mold. What is it? I've used my portable fire pit to burn scraps & pieces of disposable wood and spring pruning off of the junipers and othe decorative wood in the yard. Got the fire so hot, i had to stand 20 ft away. Very good alternative. It also works great on windy days, you won't need the blow dryer.

Liked the video.

If you were to line your furnace with some fiberglass insulation your melt times would decrease dramatically.

This is fantastic I'm thinking of using cast aluminum as a substitute for unobtainium to replace a couple Miss parts for a current project

[JohnSmith-kieq]

Be VERY careful if you used a galvanised container, burning off the coating produces poisonous fumes that can kill, so burn off the coating in an open well ventilated area.

OK so I tried this and it does work. Thing is, I couldn't find a paint tin small enough so had to go with a larger tin. As you said in the video, it did take more wood. Problem is it was a amount of wood. I have a lot of precut pallet wood but I got about 8 cans done and needed to fill the tin twice. At that rate all the wood will be gone in no time. I also noticed that the crucible kept falling over and it's difficult to keep adjusting it as the fire gets so hot that it's hard to get close enough. I think it's back to the drawing board for me.

I'm not questioning the viability of this, but this is more of an engineering type question. Would not it get hotter if there was 1 source of directional wind at the bottom opposed to many? Like a 'rocket stove', or am i just wrong about that all the way around? Thanks

Looks like ! Your Using ! Quute ! An Absolute ! Lot ! Of Rusty ! Cans ! To Make some ! Aluminium ! Here !

[Wolfe_Metals_Stacking]

Never seen it done this way before. Will have to give it a try at some point. I have some cast pieces taking up space.

[ELPasoTX]

This is just what I need! I make 1:250 scale model airliners from wood if I could make a sand mould I could cast the fuselage and wings and make many of them far quicker than carving the wood! I will use drinks cans and used foil. I might use charcoal however as it burns a lot longer than wood.

How do you deal with the large amounts of aluminum oxide that will form when molten aluminum is exposed to atmosphere?

[michaelabratzel]

From my experience, even in a a 16cm high container 'air flow management' could be an issue.

Did you try it with less holes?

In my guess at least those 10mm holes on the side are contraproductive.

And maybe only one row of 22 or 20mm holes on the side.

[unknown_bravo_]

can you also use graphite cans for the crucible?

[bruce-le-smith]

That was very fun and easy to follow, thanks!
