Building a convertible Waste-oil Aluminum Foundry/Forge Out of Scrap Metal | Free Aluminum Scrapping
HTML-код
- Опубликовано: 29 май 2020
- This was another necessity project to further my building capabilities. If you've been interested in building a forge or a foundry and haven't gotten around to it yet, hopefully this can offer you some inspiration!
With this foundry/furnace/forge, I can now make my very own cast aluminum parts and pieces for upcoming projects while not running expensive propane while still having the consistent heat that isn't offered by a wood-fired foundry. It's also a great way to use up old waste motor oil, vegetable oil, or any other kind of (safe to burn) waste oil!
If you have any questions about this project, feel free to ask them in the comment section and I will try my best to answer to my best abilities!
Thank you so much for taking the time to click on this video! If you enjoyed what you watched, then please consider liking, subscribing, and checking out my other videos!!

If some one else said this already, my apologies, your use of the inlet as a pivot point is engineering eloquence. Kudos!
Thank you so much!!
@@randomn6473 yes definitely some cool design ideas here. some things to consider for upgrades; atomizing spray nozzle for oil(could make one from aluminum melt ;) ), fan control and oil flow control. with these two we can control the oil flow/burn rate and wouldn't need the cyclone pre-burn chamber however cool it is(seems like extra complexity/point of failure?). you mentioned a door so that is all i can think of. great build, thank you for sharing!
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.
Great burner turned out! I also recently made a burner according to the secret drawings of the USSR. It works like hell))
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...
1:00 CAT loves the foundry
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!!
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.
Firstly, I really appreciate your kindness and support. I think quite a few people have interest in building them, but there just isn't a whole lot of info out there on them. I'm so glad this video could help!
Do you have plans for this? If so are they downloadable?

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💯🙏
We could certainly move away from this consumer make junk to throw away society
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!
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.
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 RUclips creator favorite list!
Edit: Just thought of something... if you had used diesel fuel as a bond breaker for the inner liner it may have released easier... also adding some form of vacuum break to your fuel line to let it clear all the way to the tank could make for cleaner transport and handling.
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.
Dude! Thank you for the idea I have a ton of oil and I’ve been meaning to build a forge
Glad I could help!
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.
nice combination of tools build. I always love to see the two or more tools in one kind of thing.
Great how you explain everything in detail at a lightning speed, I like it and do appreciate that lever xD
You're a freaking genius! 🤗💕🦄
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 🙏
Great explanation ! Thank you for sharing your project with us
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!
Damn! I only found out about his death because of your comment, nearly a year after he passed away :/
P.s. I really enjoyed Grant's forge videos :)
your inventions are saving the environment wherever u are just a little bit
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.
great design, good way to use old motor oil without pollute air!
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.
Thanks...I’m going to be building one soon and you’ve given me some great ideas and advice 👍👍👍
You're design is GENIUS! I mean, amazing concept.
Great to see a new video.
Loving the content and the explanations
Glad you like them! Thank you!
I don't understand why anyone would dislike this, unless they secretly work for OSHA.
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.
I'm still waiting for the turbojet wood gas engine I suggested on Instagram haha. Awesome build dude, great to see more from you!
Vv. C ml. .. l
I want a wood gas foundery as well
This is sick! I want to make one of these with my dad! It'd be so cool!
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
Thanks for the two in one idea Now I’ll have to make one
Good job. Now I am going to have to make one.
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.
Would love to see you try making bronze in the foundry!
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 Tate
Dam man your smart as hell! Great video! Keep up the great work!👍
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!
Another brilliant video
Fantastic design and build, again I'm impressed. Oh, wearing of cotton clothes around flame is great advice.
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 👍💯😎
Great Idea, yes I could use some cast parts!
fun seeing!
Awesome! Great Job!
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.
this gave me several great ideas. thank you for that. I wonder if it would make startup any easier to add a propane burner to it for initial burn to warm the burn chamber before switching to waste oil.
also, what is the sound track at the end of the video?
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.
I like your explanations, but especially your confident tone. KEEP THAT ON :)
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 RUclips, but never built one. Anyway, I gotta go see your heater build!
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!!!!
Great build en very nice explanation. Thank you
Nice Job!
Wow,,, it even got ,,,, a cat scan.😂🤣🤣👍 Thanks man.
Super cool site. Love it. Will tell everyone
Love the idea i will be trying to build my own.
Watched it all. Quite Interesting.
Awesome, thanks for sharing. Question: what do you think would have been a better release agent for your cement form besides cellophane? Grease?
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
Watched it all the way
Holy crap he is back!
Nice forge/foundry setup! i noticed that flame hitting that railroad spike handle pretty good! don't forget your gloves!
Nice job amazing job
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.
Thats pretty smart!
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 😁)
Great and helpful.
Very good !
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
Thank you for the comment! I will probably end up purchasing one soon. I saw that, but I'm not too sold on the idea of steel wool. I'm wondering about the flammability there.
Great content!
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.
This is awesome! Thank you for sharing?
I got so scared u had stopped making videos cause you released a couple in quick succession and then tailed off
great sense of humor
Thank You for a wonderful vid✔️
In my own experimenting, anyone reading this ALWAYS make sure to preheat any sort mold also know that there are 2 different types of aluminum explosions are possible do dilegent research and stay safe.
Yes I experienced the worst type and no I've not seen much about it on YT finally yes I did get hit with molten Aluminum but very very lucky I really didn't sustain deep burns.
Now suddenly having a forge myself, I know that the refractory has to glow before it's hot enough to forge. Would be curious to see if your system could be tuned to get that hot. Or hot enough to use as a kiln.
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.
You are a fellow McGyver like myself ! Good on ya m8!
Once I saw the presence of an official Science Cat, I knew this project would succeed.
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.
Hello. So from observing all your videos thus far I have an interesting idea that perhaps you will find of interest. What are your thoughts on wood gasifier that produces both gas and charcoal and for burning you utilize waste oil? So in a sense all charcoal after is for other uses.
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. :)
Very very amazing nice job because of your vlog tutorial I got some knowledge from you about that your vlog
What a beaut!
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.
Awesome project build and design. Question . Where the oil feed pipe tee's into blower to burner line , is there a reduction jet of any significant size in line? Thanks
the forge foundry is a great idea I am doing the same
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 build... Do you think flipping it to opposite direction would be better so the flame is on the bottom on blacksmith mode because the direction of the outlet pipe into the forge?
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.
You're amazing! Great ideas!
Would you consider making your "tank" run on wood gas? I would love to see that :D
any natural fibre is good, an old wool sweater is also excellent.
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.
Have you thought of any changes or upgrades you wish you had thought of doing the build now that several months of use has happened? I like this style of unit, reminds me of a model of the BOF furnaces in the steel industry back in the day!
that looks good for the enviornment
great work!
Thanks a lot!
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!
Jesuit H Chris... You just got an auto darkening hood? Are you in New Zealand?
holy shit, plaster and sand?!!! wow... dude, try bentonite clay, diatomaceous earth earth and Portland cement in a 1:1:1 ratio. way less likely to explode. The diatoms are the heat sink, the bentonite keeps the thing from cracking and the portland keeps it together. You still have to heat it slowly the first couple times, but way less scary and also still cheap.
