I like the end product. You have grown your skills since beginning your channel. Keep it up.

Excellent video. What a lucky hypothetical girlfriend

Have you ever used a waste oil burner in a 55 gall drum to melt cans put a hole in the bottom for the metal to pour out waste oil will melt it engine blocks in 5 minutes that are made of aluminum once it hits temp and that takes about 15 to 20 minutes I'd like to see someone melting barrels of cans in one I'm planing to build one I saw some that use fire bricks in the bottom and all the flag is caught by the fire bricks as the metal runs down around them I'm going to use an old 100 pound propane tank when I build my melting furnace it don't need insulation on the drum the burner is so hot

Hello How much does that engine cost? Thanks.

I love this editing style mate!

I would guess that the orange tent of the ignots is from the orange sticker that was left on the bottom of one of the larger items he melted. It may have been the last item he put in. I was wondering why he didn't remove that orange sticker. I would remove any and all stickers, etc., for purity.

Отличные слитки получились из посуды. Кажется мастер идиот.

Looks like it has a good amount of bismut inside, not a pure tin

Use the gallium as the lubricant instead of oil.

Currently studying Material Science in my final year Physics degree, this has helped and made a lot of sense especially when you talked about Work hardening. Now the theory makes sense with practical

What would hsve happened if you had put it directly into the engine oil and ran it ???

Oil will protect the aluminum.

Maybe putting the gal in the coolant circuit would be more effective.

I see why it's called blacksmithing

Great vid. Sand paper the the top or drill small holes and do it again.!!!🎉

So i was going to use some refractory cement, but my biggest gripe with it is, i dont want the weight of what basically equates to a big block of loose cement wearing down the ceramic through movement. Using a thicker layer of cement of course

I would think of you out the gallium in the oil let it run the gallium will melt and mix with the oil leaving little gallium crystals all over the place when it cools. Then starting the engine cold might scratch the surfaces it is in contact with causing it to start reacting then leave the engine a few days and try to start it again.

I’m impressed! I thought the engine would fail, with the piston rings chewing the cylinder to hell. Could you do it again by just mixing the gallium into the fuel?

Rod = round Bar = flat* Forge = typically used for knife making, hobbyist sizes are smaller than furnaces and aren’t designed to melt metals, only heat them for forging, often with hammer and anvil Furnace = used to melt metal by heating it in a crucible* Foundry = where the furnace, molds, casting sand, crucibles live, and where metal pouring/casting etc takes place *what is seen in the video - in this case, a furnace is used to heat steel so one could argue that makes it a forge

Good video I think you need some music tho. Disco inferno would be a good choice.

Very nice video. Needs some music. I suggest "disco inferno" burn baby burn :) Anyway, I wonder if you could produce less slag or copper oxide during the remelting to obtain a better yield using various fluxes, nitrogen atmosphere furnace, alumina or zirconia (zircon) crucibles? Also, it would be fun to see various you create various alloya the copper with different metals and ratios (tin, zinc, magnesium, lead, gold, silver, antimony, germanium, bismuth). Then analyze the alloys in various states of crystallization (e.g annealed, work hardened, aged, tempered, solution treated, homogenized) then measure hardness, corrosion resistance (Gibbs equations), ductility, conductivity, ect. :)

I'm pretty sure precipitation hardening is an other word for quench hardening. Rather, quenching precipitated the dissolved alloying elements to form martensite and other structures. I make knife blades from hardenable bronze. I forge the blades by hand, and temper them on the fire. It's important to note that on a lot of aluminum bronzes for exemple, the hardness doesn't really come from the quenching process (the bronze doesn't harden much after quench) but from the decomposition of the martensite, aka tempering / aging. However tempering aluminum bronze is still pretty unexplored, and even the latest research papers don't give very precise processes. So i personally had to practice and find for myself a method.

it just occurred to me that the fabled metal of Atlantis was tempered brass. normally bronze is better but i think hardening brass might be how we got the idea for forging

Spoiler: the answer is no. Just sell em to the scrapper. No melting necessary.

Subscribed because of the 8-bit avatar art work.... and the great content.

is a rigidizer absolutely needed?

next time no music thx

I'd guess the reason the gallium didn't eat the aluminum is the coating of soot. Even a thin layer of oxidation can protect against the reaction of galium from what I've seen in videos. Often people have to scratch up the surface to start the reaction if the metal isn't freshly cleaned beforehand.

'i should call her'

I thought it would foul the plug.

Bud take the head back off, scrape a layer off the piston, and bead up the gallium on that location! Test every 5 to 10 min youll get a result!

Plot Twist! Somebody sold Mercury to him instead of gallium! Dund dun Dahh.... and he been handling it...☠️

Need to show a video on melting down that copper wire. That is where the big money is.

Best vid yet

There we go this’ll bring in the VIEWS

What gave you this idea to test if gallium will destroy an engine? Did you hear someone mention something about it? Just wondering what prompted your curiosity.

If you're going to melt down cans for profit, you're better off using molds for jewelry or decoration. You could sell a 2in crucifix, for example, for about $7 profit after polishing it.

Would be nice if you listed in the description all of the equipment used, the costs of it, when applicable, and links to where you bought items you had to purchase. Thank you for considering doing this in your future.

Of course, do Ingots normally sell for a decent price, say how much money would I receive for an Ingot that was 10kg?

I think you might want to temper the wood first

great video

Hah. I have been wanting to do this for 20 years! Thank you Thank You. I keep suggesting to do this very motor vs gallium experiment to the Project Farm yt channel for several years now - but no luck yet! Really love that you did this. I suspected it would be hard getting the gallium to take to the aluminum. I have seen people struggle to it only working on a very fresh scratch. Again - Huge thanks for trying this!

There's no garbage service where I live, and I have an energy drink addiction. The cans add up quickly and by the time there's theres so many that you have to do something about them, the raccoons have destroyed the bag for some reason and putting them in the car isn't an option. Touching each one is necessary one way or another. I'm considering melting them, if only to learn a new skill and solve the problem

Explanation in easy terms for beginners: Steel hardening: Heating it will change the inner structure from one state to an other (cubed lettice structure will change inside) --> suddenly quenching it will cool the steel rapidly down without giving it´s inner structure enough time to change back again too it´s normal room temp state. This creating inner stress and making it harder. To release the stress yo ucan heat up the material again to about 500°C and let it cool down slowly which will change some but not all structure and release acess stress thus making the material still hard but not brittle. Aluminium hardening: Heating it will relax the material and alloy components like copper can move freely (495°C-505°C with the help of a candle you can reach this temp without melting the part), all the alloy contents will be the same roughly everywhere within the metal --> quenching it will not change that, however the metal structure will now start to change at room temp. The alloys want to create small islands and will clump together and thus hardening the material You will be able to notice a difference already after minutes. It´s full strength will be reached in about 4 days. You can speed up the process by warming the part, simply put it in an oven at 100°C or so for a while. The colder the temp the less the atoms can move. In aircraft design the metal will be cooled down to below freezing ca. -20°C, to prevent it from hardening too much before it can be riveted.

You should put it around the sparkplug and into the oil. So its not out in a milisecond

precipitation hardening isn't age hardening, they are both different steps in the actual hardening. Basically it's like steel, but the opposite. when you quench steel it hardens, and you heat it up to disperse the martensite and have a more souple and flexible structure, but in a lot of non ferrous metals, quenching won't really harden the metal (quenching is precipitation hardening btw, beacause the alloying elements are expelled from the solution and form the martensite), but then heating it back up decomposes the martensite, and oddly enough, it's the decomposed martensite that actually becomes harder and stronger.

How long does a propane tank last using these?

I didn't think it was going to start that second time.

I put a dislike because you called it a forge when you use it to melt metal. You melt metal in furnace and the place you melt and cast it is a foundry. A forge is a facility for shaping hot metal heated in a furnace usually by hammering it to the desired shape. The furnace or fire as we called them is not the forge. (I workd at a forgemaster in Sheffield UK)

Thanks for puttin this together. This will be a lot safer than the method I've been using!
