For those interested, if I'm not mistaken that's 4 scoops of gypsum, followed by 6 scoops of fine sand, (could be a clay sand mix) mix to consistency as shown.
Quit using gypsum in your refractories and you will get much better results. Hydrates dehydrate at high temperatures and loose much of their strength. Gypsum in particular also breaks down at heat.
@@shawnsmith9512 yes, I agree. Silica is much better, but precautions must be taken to keep the dust out of your lungs. I was simply filling in missing info from the video.
Fantastic job, if J. Gingery could see your version he would admire the confort of feeding the oil instead of charcoal as I admire. Just a single question if posible, ¿how much time does It take after closing the top cover with the Al pieces inside to reach enough melt temperature to take to the mold?
a tip for bending tubing (if you don't have a tube/draw bender), is to pack it full of sand first, seal it, then bend with medium heat; will keep tube from buckling.
When smelting aluminium in an steel crucible, the aluminium would always eat away the steel until the crucible would leak. Maybe i made it to hot and thats the problem
Aluminum shouldn't but I would think the crucible got to hot and the weight of the Aluminum behind the steel being weak from heat the weight is what made the hole
@@1000186ful maybe, but it also made an alloy that was barely workable with a file (verry hard). It also didn't deform the crucible and left a hole as if acid would have been inside.
Coś w tym jest. Mam podobny problem. Stalowy po 2-3 razach cieknie, nawet zmiana na grubszy materiał wiele nie pomaga. Jakby gorące aluminium robiło się jak pocisk kumulacyjny. Zmieniłem na tygiel grafitowy i na razie działa.
Add a layer of titaniumdioxide mixed with water-glass to your gently preheated iron crucible from inside and outside before melting aluminium, it will last longer.

you can fill the gas tank with water and then empty it. the water will push the residual gas out and normal air will get back in when you pour the water out
Yes exactly. I have used that method to repair fuel tanks in the past. However, there is no mention in the video about the danger. In my town maybe 20 years ago a man was killed when he took an angle grinder to an oil drum to make a barbeque. It exploded in his face.@@leenux1707
Yeah, that was not a cylinder from a flammable gas, but yeah, purge any cylinder with water and an acidic wash and you'll be good. Even have the cylinder mostly full of water for your initial cut, until it's open. Risk management. Purge it with a running vehicle exhaust even.
I like that you didn’t hide mistakes and failures here, but simply how you fixed them. Good job, I wish I had your skillset and tools
Шикарная идея,очень познавательное видео,спасибо за идею и Ваш труд!)

Excellent idea and workmanship. Thank you for sharing.
very professional fabricator and quality idea very impressive
Thank you for the great video. Have a great day 👍👍👍👏👏👏
Parabéns meu amigo ficou muito bom mesmo, vou fazer um desse para um amigo aqui ,muito obrigado por dividir com todos nós
Wow this is great
Nice 👍
This is the first video where someone has a guard on the angle grinder
Very good video

how does the oil burner work? simply dripping oil out the front of the pipe?
Clever❤
how you put oil level. Lower air hole or uper?
Where can I buy a fan like this?
Line benders are a thing and really inexpensive
👍
❤❤❤
What is that? Aluminum? That could have been accomplished with a $20 torch and a used terra cotta pot. How about iron or steel?

maybe its metal..but its not iron...its lead hehehe
Sir what kind of materials you use plsidentify

Good little burner but video should be called 'how to build a budget burner' .
Pity about the music too .
a lot of trouble to melt lead. If that is what it is and I'm pretty sure it is.
Taking an angle grinder to an empty gas cylinder is a very good way to decapitate yourself. Don't try this.

Refrigerant cylinder, perfectly safe. Only problem is acidic gas when residual refrigerant burns.

That one is not used oil.
Melting *ALUMINIUM* LOL
Irritating music rather than silence
Why can't we see the project with an explanation before having to constantly skip through watching boring construction videos first.
DIY videos without narration suck but when you add crappy generic "music" it just makes some completely unwatchable!
Great job! o7
