building a dirt cheap waste oil foundry (0 fuel costs)

[@qweef69]

Those adapters are called bell reducers

[@hazlox]

Spray the kaowool with 50/50 water and sodium silicate to harden it :) it’s the industry standard or use clay slip

[@raukorist77]

By clay slip are you meaning like soak it? Or spray as well? Or just coat with slip. Husband of a potter so I have slip readily handy

[@hazlox]

@@raukorist77anyway will work honestly. Just getting something on is key. Id spray with pure slip then add cob for another durable layer. Then fiber cement for final layer

[@spacecase0]

Thank you for the video. I had no idea you could start an oil burner with oil soaked paper like that. Everyone else I see uses propane. Significantly harder to set up. I look forward to your next video

[@jonpierce8342]

Nice! I was commissioned to build a siphon spray waste oil burner years ago... Had a lot of fun doing the testing with it until I burned up my air compressor.

[@eduardodaquiljr9637]

the gas or fumes that evapoprates from used oil is gaseous and the process is called pyrlysis.When evaporating gas meets the air blast,combustion takes place by igniting.You can boost the flame by secondary blower.Thank you.

I made one just like this out of a metal bucket with a lid, it works with charcoal too

[@braddavis4377]

Good video. One thing I noticed with tutorials like this is that there is not much theory; there is much to show about how things are done, but l think, it's good to include the calculations behind what you did, so that if I want to scale my design, I have the tools to do that, like, what size burner I need to melt x amount of metal. That might be very useful info. Keep up the good work!

[@ebrahiemmurphy6506]

Loved the video, you should checkout Julian HG channel he uses a fuel pump with voltage control, with variable power for the pump and fan , he melted bronze. Keep up the good work. Thanks for sharing.

[@Thee-_-Outlier]

You have the makings of a TKOR'esque channel here. Good Luck

[@michaelsimpson9779]

Thanks for this content. Well presented.

[@jesperwall839]

Well done! 👍😀

[@JoTheVeteran]

Won't whatever you're melting be infused with the metals inside the oil? Primarily iron, steel, or iron oxide. I would suggest you remove all the iron using strong magnets to collect it on the bottom of a container, then slowly empty from the top. Also, isn't obsidian practically glass? You could actually make some stuff if you were to pick it with a steel rod, and blow on it. Then separate it using twisting motion, and red hit tongs.

[@PyrotechnicalScience]

Technically a small amount will but used motor oil contains about 10ppm lead and 10ppm other heavy metals which will mostly just leave in the exhaust, iron has the highest concentration of about 70-330 ppm which isn’t really much to worry about contaminating your metals. It’s pretty much glass as most rocks are made of silicon containing molecules much like glass which is silicon dioxide, so it should be possible to glass blow it, maybe I’ll give it a try!

[@goodmoodgoodday5385]

pretty interesting, do you have date what temperature you can reach with this system? I like to rebuild for my ore smelting process.

[@DarrenMalin]

would make a night blacksmiths forge. Well done Sir :)

[@amazingnew1]

Good work .thank you for nice idea

[@builtbycarma]

Awesome👍🏼

[@VerbenaIDK]

i wonder if a version could be build that works on heated ethanol/maybe idk amonia i always loved the idea.of using amonia as fuel for some.reaaon

[@PyrotechnicalScience]

Possible but I’d switch to using a sprayer head instead also might have some issues with your fuel boiling in the feed lines.

[@VerbenaIDK]

@@PyrotechnicalScience i would actually want to the fuel to boil in the lines, akin to a regenerative cooled rocket, so i'd keep the copper pipe near the body of the thing so it heats up alightly before being injected, and pobably make several holes in it to inject fuel from everywhere and near the air input, but then, i'd need a pump, but a fuel pump pobably would do it ig, small 12v ones sold for cars or something but then i am getting closer to a jet engine... about amonia, i'd pobably need pure oxygen or it wouldnt burn at all because the flammability range of amonia is shit

[@shortsenstuff]

its a nipple not a coupling or coupler good work though

[@shortsenstuff]

refering to the small threaded piece of pipe joining your reducers

[@tomcook5813]

Can you still use that crucible for casting metal?

[@PyrotechnicalScience]

Yes

[@Wikawo]

Try to fix the kaowool lid. Those fibers are dangerous

[@MarkPhilippNeumann]

Great video mate! I wonder what could be the estimated fuel consumption per hour of running it? A liter of waste oil maybe? I have lots of carshop owners as friends and can get an unpresidented amount of change oil from trucks and cars haha.

[@PyrotechnicalScience]

Really just depends how hard you run it and how big you make it! I’d say it’s more like a liter every 15 minutes if your running it like I was!

[@MarkPhilippNeumann]

@@PyrotechnicalScience I see! Thanks for the reply!

[@طارق.محمد.ش]

Good

[@afipantera]

I like your videos, but every time you pronounce the letter “s” in a word, you pronounce it as the “sch” sound. In speech, its called a slush. Its hard to watch, but i know im picky, and i still like your content
