Building a convertible Waste-oil Aluminum Foundry/Forge Out of Scrap Metal | Free Aluminum Scrapping 

If some one else said this already, my apologies, your use of the inlet as a pivot point is engineering eloquence. Kudos!

About time you pet that poor cat. Little bugger was keen for some attention 🤣🤣🤣

Thanks for the video it gave me inspiration for a smelting foundry/forge I have had in mind to build for myself. Here are some ideas you and others may like. If you''re melting aluminum any iron or steel tubing with one end capped and welded will work. You can have the steel crucible from the bottom of the furnace to a few inches from the top of the inside of the furnace, that when a lid is on it, there is escape heat that carries the full length of the crucible. If you build ring out of iron to keep the bottom centered and another ring onthe top that can be bolted to the outside case of the furnace securely that is welded to the crucible, the tilting fuction will allow you to pour your molten metal into molds if you design a catch funnel that has a fine strong iron screen to catch any ferrous metal nuts, bolts, etc... and use iron pipe/tubing to flow the metal into your casing cone or molds. Always before pouring molten aluminum you need to degas it with sodium carbonate block pushed all the way to the bottom of the crucible using an inverted cone on a long metal rod - leave a few inches below full for this outgassing - stir the melted metal until it settles, add a fluxing dross (buy it online) and then skim off all dross for a clean melt as oxygen in the air forms aluminum oxide that has a higher melting point.

This has overnight become my absolute favorite channel I love this advanced diy content, I’m a welder myself and this channels given me so many ideas for some side projects and honestly I hope more people see this type of stuff bc we could all use some more hands on ideas to improve the world💯🙏

The dual-purpose design is a great idea and I am shamelessly going to copy all your best ideas. Thanks. FYI Carpets are rolled on very strong cardboard tubes up to around 12" in diameter. It doesn't really need it but you can seal it with spray lacquer to keep it dry while the plaster sets and then you can just burn it out. Carpet fitters are happy to give it away.

i’ve been meaning to make my own foundry, and thankfully it’s you to guide me through it. You’re one of my favorite creators, and are very explanative.

your inventions are saving the environment wherever u are just a little bit

1:00 CAT loves the foundry

This is sick! I want to make one of these with my dad! It'd be so cool!

You, sir, have an excellent talent at making a great making video! Love the skillful application of timestamps and guidance! Thank you for expanding my RU-vid creator favorite list!

You remind me a lot of the late Grant Thompson in the early days of his channel. I love your content dude. Looking forward to the next video!

I don't understand why anyone would dislike this, unless they secretly work for OSHA.

Dude! Thank you for the idea I have a ton of oil and I’ve been meaning to build a forge

Im a heating guy, just gave me a great idea of using the furnaces heat exchanger w plaster to melt in a crucible, gonna try that this summer.

Thanks for the two in one idea Now I’ll have to make one

Buddy, I've been waiting a looooong time for a new video from you. This foundry/forge is badass! Thanks for describing all the steps in detail. You've got some real talent and you obviously smart as smart! Kudos! P.s. Plaster of Paris expands when it cures. Opposite of concrete...

Great burner turned out! I also recently made a burner according to the secret drawings of the USSR. It works like hell))

You're design is GENIUS! I mean, amazing concept.

One trick I found when making the interior cavity - pull the form out when the plaster mix gets close to hard dough stage, the walls will stay solid but the form comes out easy.

You're a freaking genius! 🤗💕🦄

Watched and commented on a couple of video's so now I'm subscribing.😎 I just wish I was younger and still had your enthusiasm for everything (but I'm old, tired and cynical 😁)

When I worked for an ornamental plaster company we would use Crisco to coat our moulds which made removing the plaster very easy. But in this case you are also dealing with a lot of suction. Very cool build!

great design, good way to use old motor oil without pollute air!

great sense of humor

I like your explanations, but especially your confident tone. KEEP THAT ON :)

Awesome! I made a waste oil heater for the shop and it worked so good I wondered if I could forge with a setup like this.. and here you are doing exactly that! Thanks for the video!!

Wow,,, it even got ,,,, a cat scan.😂🤣🤣👍 Thanks man.

Watched it all the way

For removing the fire extinguisher from the plaster, try wrapping it in a few layers of that thick brown masking paper that painters use. The plaster mixture won't penetrate the paper and it'll have a bit of give to it as the mixture expands slightly when it sets up, so you can just pull the fire extinguisher (or whatever you're using) straight out. There'll be some of the paper left stuck to the plaster but that'll burn away pretty easily the first time you fire it up so who cares. Could also use a thick-walled cardboard tube but it'd be hard to find one that's the right diameter and is also strong enough not to get crushed by the plaster, and I'd avoid a sonotube since those have some sort of coating on the inside and I don't think burning whatever it's coated with would be a great idea.

any natural fibre is good, an old wool sweater is also excellent.

Dam man your smart as hell! Great video! Keep up the great work!👍

Fantastic design and build, again I'm impressed. Oh, wearing of cotton clothes around flame is great advice.

Good job. Now I am going to have to make one.

A picture is worth a thousand words...🤔🤔🤔🤔

As I said in a previous comment: I will look for more. Once again, Well Done. And good work. I was actually looking at forging when you randomly showed up. I won't criticize, you already hit that. I'm actually amazed that you have so many ideas, and many of my skills and knowledge. If I may... A cooking hint concerning your refractory: mix your dry ingredients first. Slowly add water to desired consistency. Pour your bottom to the depth needed and let it set partially while keeping the rest. Coat the inner form with lard or petroleum jelly (oils are too thin). Alternatively, leave it to concentrate the heat. By the time it burns out, you will have compensated... Or moved on to something else.

You are a fellow McGyver like myself ! Good on ya m8!

how can you be such a master welder, designer, fabricator and still not have an auto darkening hat until today? and use a flat file on a round hole? brilliant, man, it's brilliant. thanks. :)

This is pretty cool! I’ve built several of my own forges (and cooked my most recent one) and I am currently working on making my own foundry as well. I’ve never thought about using waste oil as forging fuel and I’ll give credit where credit is due, it’s not a bad idea at all. I will say that it will produce more smoke and fumes which will be hazardous to work around though.

I was fully expecting for you to pan over to see your welder is a couple of stolen RV batteries with jumper cables. Good show! I love it!

I'm still waiting for the turbojet wood gas engine I suggested on Instagram haha. Awesome build dude, great to see more from you!

Great idea for both a foundry and a forge in one. I do my own oil changes on the farm and I want a forge, didn’t think of about a foundry that I could pour other products from aluminum cans and sell. Thank You 🙏

I like the 14:50 didnt work segment before and after. comedy gold

Would love to see you try making bronze in the foundry!

Great build en very nice explanation. Thank you

I love the detailed jump ahead info on the screen in the very beginning, and I love that this isn't one of those stupid silent videos, thank you! Subscribing and liking just because of that 👍💯😎

Once I saw the presence of an official Science Cat, I knew this project would succeed.

Thanks for all the info.I might be using your idea as it to me is the best I've seen on any channel. I really like the double duty idea.you amazed me enough to subscribe so I can catch up and or not miss any of your content. Thanks again.

Great how you explain everything in detail at a lightning speed, I like it and do appreciate that lever xD

Nice forge/foundry setup! i noticed that flame hitting that railroad spike handle pretty good! don't forget your gloves!

I do like your setup. Been waiting too long for proper cement. so I will be doing the same with added materials.. Vermiculite and Perlite. In college, this was added to plaster mold material so as to use less plaster, Insulation, and the ability for the cement to vacillate in a more spongy format less cracking. Very good design sir!

Nice job! One way to make your cavity in the forge/foundry is to use a paper-based concrete pier form. You can cap the bottom end with a sacrificial cap and drill through it for your inlet. Best of all, to remove it, just fire it up!!! It will go away like magic! Actually, care should be taken when burning the form off since pieces might flake off and blow burning up into the air. I've seen so many of these foundry builds, even before RU-vid, but never built one. Anyway, I gotta go see your heater build!

OMG I'm so pleased i watched. , its called cling wrap not release. Thanks for sharing your fails with the success.

liking for the aluminum can pun

It's great. One suggestion: I would weld a spiral metal pipe around the combustion chamber to pass the oil through it to pre-heat/evaporate before feeding into the airstream. I expect a significant boost in burn efficiency.

Very very amazing nice job because of your vlog tutorial I got some knowledge from you about that your vlog

the forge foundry is a great idea I am doing the same

Great explanation ! Thank you for sharing your project with us

nice combination of tools build. I always love to see the two or more tools in one kind of thing.

Nice job Tate

Fantastic!! I have to make an adapter to mate an opposed twin experimental aircraft engine to an MGB flywheel and transmission to build a 1928 Morgan RIP GN hillclimb racer replica which was made to look exactly like the way airplanes were made at that time.There is only one in existence so my replica has to be perfect and although Morgan used a sliding chain gear assembly I am keeping it British with the MGB transmission and an MGB differential with the beautiful wire wheels. I am going to cast the adapter then chuck it up in the lathe to make it perfect. Thanks for sharing your build.

Great idea, I'm in the process of building one myself. I think I will use parts of your build like the stand and pivot for using it as both forge and foundry. My insulation will be cement (Portland) perlite, vermiculite and sand. My tank will be a 10 gallon bladder water tank that will be a bit bigger than the propane tank

Great project, well done! If you ever need the plaster to be super-insulating, think about using perlite in place of sand. Also, you were concerned about the paster of paris setting up. It sets up in less than an hour in warm weather.

If you haven't already I would look into a graphite crucible and Grant Thompson made a follow up video about his foundry where he lists so things that helped the casting last longer like putting steel wool in it. Also great videos love the style of figuring out things as you go

Bro! I just finished watching your biomass gasifier video. You could run the gas from that into your foundry and get a much higher temp. Necessity is the fuel for ingenuity. Good job

I got so scared u had stopped making videos cause you released a couple in quick succession and then tailed off

That was pretty cool. I'd use a ball valve and should add a flash arrestor at the end of that hose. Just in case. And I'd put a door on that thing maybe w a little window that sides open or whatever you know. Thanks for the build though.

Just saw this. Ive had similar ideas for years but never done it.

Restaurants are a great supply of oil as well. It smells really good when you're burning it too

Nice. Been talking about making a home made forge. Wasnt sure I liked the idea of ether propane or coal. But waste oil? That's a great idea.

An idea for removing the tank from the cemant. A long bit, drill a hold in the bottom and apply air pressure. Oh also apply grease to the taml for lub and to prevent sticking. Just an after tought. Great video's and keep them coming. Thank you. J.D.

fun seeing!

Great Idea, yes I could use some cast parts!

Great concept, a lead is the key to a hot foundry, cut ya a three inch hole and I like koawool in my cap. Great job and great info.

Nice Job!

Nice job amazing job

Thanks...I’m going to be building one soon and you’ve given me some great ideas and advice 👍👍👍

Love the idea i will be trying to build my own.

Well done, and thanks for sharing, ill be duplicating this design, and will start burning used oil as a means of recycling

Super cool site. Love it. Will tell everyone

Melting aluminium with firewood, hole in ground, and hair dryer. You have my attention

Needs drop down wheels to make your life easier while moving it Rando! Otherwise amazing build. Use a two bar linkage on both sides of the axle for the wheels that picks up the back and detachable rail so it works like a dolly with a permanent load placed upon it (the forge furnace). You took this the smarter route than when we made a forge that "can" smelt in our shop. As room is a premium for us as well. Post-Post Note. That top? Great plan its what we have, make a hinge from scrap round stock and sheet, works great. Bit of Kaowool and refractory for the lid to not have to redo it in the future and you're golden. It'll decrease warm up time for smelting and achieve higher temperatures for heating up your forge for smithing pieces. We did something similar for our forge and just called it a blast door... because... nerd joke. Not sure if you should keep the hole exposed or sealed though. Pretty sure you'll burn more of the fumes and have a cleaner emission coming from that waste oil, but at the same time it could put more impurities into your smelts and your steel for forging.

Being a plasterer next time lube the cilinder and remove that day you will know by touch it will not collapsse. Great work.

that looks good for the enviornment

Great and helpful.

When I did my first mini forge from King of Random video it only lasted 3-4 melts and crumpled horribly. Second time around I mixed the sand with plaster as much as could while it was still dry and only than added water and I had same problem with trying to remove plastic bucket, but man it was crazy how you tore apart aluminum fire extinguisher!

Very cool project brother. I just got around to this one and it's a very cool and unique design. Your video style reminds me a lot of Mr Teslonian, (with a little less apocalypse setting and feel) that's a good thing. Your view counts show that people like what you are putting out. Keep them coming. -Shane

interesting video, i used to work for foundation company, building basements, for the 8" walls we poured concrete into al. panels, for a smooth finish and getting the panels to come off the walls cleanly, they sprayed a diesel/oil mixture on the inside of the panels, i think around 50/50, you could call your local co. for the specifics, but your center piece should come out much easier.

Well done

It's a bit like watching myself. =) Home brewed ingenuity, complete with questionably cosmetic but solid welds! I've also seen people use plastic buckets for the center cavity mold and break it out afterwards. Personally, I've found good success with the hard cardboard construction tubes and burn it out afterwards.

I like your design, however i would add a variable speed switch to the blower and as you mentioned a proper cover. With those and practice with fuel control, I think itll work just fine. Thanks for the video!!

Very good !

Hey man I just wanted to give you some props. I'm a new sub. I'm also new to doing a RU-vid channel and I know how hard it can be. Congrats on your early success!! I'm trying to improve my video making skills...... I can build anything but sitting in front of my computer editing videos is not my strong point. Love your stuff man keep going! I bet it would be a ton of fun to build something with ya!! Let me know if you ever want to team up and build something obnoxious with somebody🤔😏. I'm gonna go ahead and share your videos too man. They are GOLD!

Great to see a new video. Loving the content and the explanations

for casting the refractory mixture I would try using sonotube cardboard tubes, made for pouring cylindrical concrete columns. After the refractory cures, you could simply apply heat from the burner and the sonotube would burn away. Sonotube is available in numerous diameters.

What a beaut!

Another brilliant video

Holy crap he is back!

Great content!

Again, freaken awsome! Subscribed for life buddy! Love it! If you make a second angled lock you can make this thing pour your aluminum, I.e. into molds!!!!

Watched it all. Quite Interesting.
