Hi! As a worker in a steel factory I have a few top tips for you! I know aluminium and steel have totally different melting points and that but I really suggest that you work with this outside. When you drop molten steel on the floor it bounces and splashes everywhere. It will flee like rabid ants and set everything on fire. So with your next video I hope to see that your furnace and mould is on the floor with nothing that can burn close by. ;) Other than that, I like what you are doing. Keep it up!
In a time where a great many young people are gaming and wrapped up in social media this young man is learning a valuable trade. Well done young Sir, well done.
If you had possibly made a pit off to the side to pour into then allow it to slowly flow into your fly wheel. You will find less porosity in the aluminum casting, You will notice the difference when you machine it, Also definitely heating the mold to dry it out helps, You can see the gas pockets on the bottom of the casting, You will find micro pockets throught the whole casting, Just look at it with a magnifying glass and you will see what I mean. It is always better to try in some way to pour from the bottom of your crucible rather then the top, If you could have had material flow level into the pour from the crucible, you would have had a perfect pour with no gas or pockets of any kind. Use water glass to hold your sand firmly in place and you can heat this up to a lot hotter then you can with just green mold sand casting.
I can tell without question that you are one highly intelligent young man..makes me proud to see you doing something constructive. We need more young men like yourself
boy i never thought you will of such a little age.... you really beat many grown up mans.... your parents should be real proud of you, carry on with your works.... Hatz off to you.
I know it's been over a year since comments but cool video. after watching some of your lost foam castings I made some with the kids last night and they loved it. thanks for your videos and keep them coming.
If his "lack of safety" makes anyone cringe, just don't watch the video, gtfo. Go and worry about your own safety, in your own garage. I see these types of comments on tons of videos, and they are just an utter annoyance, I'm sure the kid realizes that it is dangerous, and doesn't give a shit, so just mind your own business, or don't watch the videos.
+rdizzy1 they have a valid concern to be fair welders gloves and face shield should be the bare minimum. Why take chances, it won't just burn you, it will eat your flesh if you give it chance!
Jarosh It's an annoyance for me, and it isn't even my channel, nor do I know this kid at all. People just need to mind their own business or not watch the videos. If I was him, personally, I would just delete any safety nazi comments. It is similar to telling a smoker that smoking is unhealthy and causes cancer, of course it is/does, we know it is unhealthy, we know the risks, and we choose to do so anyways. Some people choose to not give a shit, people need to realize this.
+VALE ™ Yes, a steam explosion is no laughing matter. You need to make the greensand just moist enough to compress in your hand and reproduce the shape without leaving sand on your hand and to break apart cleanly. Several YT casters show just how the greensand should look in their videos.
***** So? If he dies, he dies, it's his channel,his garage his choice what to do. Aside from that, the chance of him dying from this, is severely low, maybe the chance of him getting injured is mediochre, but not dying.
For one, he pored molten metal into a mold that is sitting on a wodden table. One leak and there would be trouble. Second, he even said it himdelf. The crucibal that was used had holes in it. Third, the shop ios a mess and filled with trip hazzards. There are others, but I won't bother noting them all.
+Richard Wheatley Thank you! I really want to do an ant hill! Problem is I can't find any since we don't really have a yard. Mostly woods. Best of luck with your castings!
Got to applaud anyone who gives things a go - but Christ man, you need to respect the temperatures involved. Be careful and get the essential safety equipment. I know there are safety Nazis on TH-cam, but you were seconds away from serious and painful injuries in this video.
Advice from someone who came very close to burning down his house. If your kiln is sitting on a wood floor or desk, always allow an airgap of at least an inch under the kiln to allow heat to escape. Without an air gap, enough heat will slowly migrate right through firebrick and ignite the wood below it.
CoolKoon I know but how much work is it to keep forging crucibles after another and you only get like 2 burns out of it before it fails. I found my 30 dollar graphite crucible to be very well made and it even got heated to 3000F and there wasn't even a scratch. It will save you a lot more in the long run rather than something that could fail at any time.
+ootie extreme That's true and graphite can be used for aluminium quite well too (although it kinda conducts heat too well, so a lot of it escapes through the crucible before the metal gets molten). Do you happen to have a good source of cheap graphite crucibles by any chance?
CoolKoon Well my crucible is a little smaller than the diameter of the cans so I need to cut them up a little but here is mine: www.amazon.com/Foundry-Graphite-Crucibles-Refining-Aluminum/dp/B00FBFF3GU/ref=sr_1_2?ie=UTF8&qid=1451516129&sr=8-2&keywords=crucible
+ootie extreme Oh, I see. That's clay graphite though, which is (if I understand it correctly) some sort of fired mixture of graphite powder and clay. It's more than fine for regular furnaces, but the kind of "arc furnace" I use would most probably crack them pretty fast. Thanks though ;)
+IAN 4000 you have no idea what field I endeavoured. this is where you watch what you say. if this child decides to play with castings that's fine. you asked a question and I have you a realistic answer that more then some probably think. now go off and play your fuck fuck games with someone else. you're trolling, it's obvious.
keith collins You're the one trolling. You came to hate on some kid's video because of his voice. The fuck else you want him to do? Tear the larynx out of a grown man and eat it to gain its power?
I think it's best to give him advice rather than tell him "this is not safe, this is not that"; at least the kid is not outside creating trouble, and is actually learning and doing constructive things with his time. That in itself is invaluable these days. Try and tell him how it can be safer instead. :)
Makerj101, @ 2:26 I am also going to highlight the danger of stepping down while carrying a very hot crucible of molten aluminium. Man that was dangerous, very dangerous. Think about safe work flow arrangement next time before you fire up your furnace.
It's amazing what you smelter will do to melt your metals an endanger your life for simple projects. I've been seeing thing that are close to breaking down but you are still using them. I'm not a smelter I'm a forger. I pull together what I need an always make sure I won't get hurt not that other have not endangered my life with their crazy idea's. But I call them family so I have to put up with them. Thank You Loader.
Yes yes, the kid needs to take more safety precautions, he'll learn the hard way soon enough and hopefully not too painfully....that's what it took when I was his age. What I like though is he is doing things he is interested in and he is learning along the way. Smart kid...keep up the good work....just be careful and don't burn the house down!
Any ideas on what too do with loads of bear bottles??? Prob better off filling with cement and making a glass wall than trying to melt that stuff right?
+\ 0909 I mean you could melt them down. I wouldn't because I have better sources of higher quality aluminum. But if that's the only aluminum you have then go with that.
try graphite powder on greensand moulds. A light coat of it will help your finish. if you want a more detailed mould try petrabond sand (motor oil and sand) it stink when you cast but holds finer details. just a lil advice from an ex foundry moulder.
I have no idea how I ended up here, but I've been watching your videos for 20 minutes stoned out of my mind, trying to figure out the fuck you doing. But seeing you working with all these different tools, melting shit and banging some wooden stick against a burnt can, I gotta say it's interesting. Love your spirit and enthusiasm! Anyways keep up with whatever the fuck you're doing!
I'm not gonna harp on you about safety, no need for a full fire suit if you're careful. But you absolutely must wear one of those clear face-shield or at least large safety glasses. I don't wear my face-shield when I'm melting, but I always wear a long sleeve flannel shirt and put the face-shield on to pour in case there's rogue water somewhere that could case an explosion. I'd also recommend looking for a cheap crucible online. You could find something decent and relatively cheap ($30-50 on Amazon) that has no danger of failing on your worktable.
have you tried bottom fed casting? you will find you get a much better casting (closed molds) because it reduces turbulence of the metal and also allows excess gas to escape through risers. it also means any slag or other impurities can float to the top without disturbing the casting.
It might be less hassle for you in the long run to buy a ceramic crucible or if you have a welder make a crucible from thicker steel. I'm gonna make a crucible from an offcut of pipe that has 8mm thick walls so that should hold up for a great many melts. Also when your pouring I noticed you had the aluminium red hot. It isn't too critical since your machining it but this can cause the casting to deform more as it cools and it lets more hydrogen gas into the aluminium which can cause bubbles. If your casting had to have thin bits in it then getting the aluminium that hot is a good idea but since this casting is so thick you don't need extra low viscosity of superheated aluminium. I like you ability to make a working furnace out of such simple materials.
+Rainbows871 You are probably right. I just like trying to do things as basic and cheap as possible so others can replicate easily. I do have access to a welder at HackPittsburgh so I may go that rout soon. For now I got a nice cast iron laddile thing at a thrift store. It's really thick. I've done a couple castings with it so far. Holds up really well. Only problem is it's kinda small. Only holds about 1.5LB of aluminium. Yeah you're right. I did heat it a little more than I really needed to. Thanks! Just something I'd been wanting to try.
i worked in a zinc foundry for many years casting zinc targets. all i can say to you my friend is all it will take is one good burn for you to realize that safety gear is paramount. while its fun and cool to cast, you should always be prepared.
+rdizzy1 this is true. but it also seems as if he has the desire to continue. he is doing a pretty obscure casting method that i myself only did a few times in my casting years. but you need to remember it only takes one time to get hurt. and even more so when you are just begining. when he started spraying it i was waiting for a spatter explosion. since it usually cools edge to center the casting may have looked solid but the center could have just been barely cooled over. i give him credit for attempting it. but leather gloves, long sleeve shirt, and a leather apron can be had dirt cheap. another worry was his limited space. he should have cleared it out a bit. after seeing his other videos he is a very competent individual. and definately has some brains in his head. safety should have been a thought in regards to this fact.
Very admirable to see a young man taking the time to learn and apply himself to something so productive, but, and it is quite a big but, PLEASE wear a leather apron and suitable leather footwear when pouring any molten metal.
glad to see someone of the younger generation carrying out such projects,keep the flame alive!
Hi! As a worker in a steel factory I have a few top tips for you! I know aluminium and steel have totally different melting points and that but I really suggest that you work with this outside.

Man I wish I would've known someone like you in my high school days. I've always loved creating things like this.

We get almost a full minute of smacking a burned out crucible with a stick, but only a couple seconds of the final product.... lol.
For real!
ikr!
+Amra LOL Yep! Sorry about that! hahaha :D
+Makerj101 Hey bud, what did you use as a crucible? (Sorry if you said it and I wasn't paying attention...)
+Amra Yah... WTF!
That's a really smart place to melt that...on a wooden desk in a garage! You're a very bright little girl!
Glad and laughed as you said "i got a fire extinguisher here" "Thumbs up" ;) Cool vid :)
+tommy sola Fire extinguisher would actually not have much of an effect on molten metal... but still it's the thought that counts right? :P Thanks!
+Makerj101 It depends on the type of extinguisher. Snow and water extinguishers probably do help....
Why is these type of videos are so satisfying?!
good job kid
boy i never thought you will of such a little age.... you really beat many grown up mans.... your parents should be real proud of you, carry on with your works.... Hatz off to you.

It's nice to see young people doing positive things like this. Good job! And keep up the good work! Subscribed :)
that is really cool, i never thought casting a flywheel would be that easy and those aluminum flywheels arent cheap at all great video!
Less time spent whacking your crucible next vid and more time with the finished wheel! Nice job too :)
I know it's been over a year since comments but cool video. after watching some of your lost foam castings I made some with the kids last night and they loved it. thanks for your videos and keep them coming.

They can keep their concern to themselves though, or not watch the kids videos.

Thats beautiful the final product was killer
be careful when mixing the sand if you use water. Because if u use too much water when you pour the aluminum, it can explode!
+VALE ™ Yes, a steam explosion is no laughing matter. You need to make the greensand just moist enough to compress in your hand and reproduce the shape without leaving sand on your hand and to break apart cleanly.
Several YT casters show just how the greensand should look in their videos.
+Mark Fryer Well, he obviously made it correctly, as there was no steam explosions, so I don't get why people comment this type of stuff.

super awesome job casting and machining that flywheel! Now try and cast your own pistons.
+Ray M Thank you! That'd be a cool project!
Shows us the finished product more.
+seeindarkness I sure will! There is going to be around 5 videos on the internal combustion engine!
@@makerj101
Why the potassium nitrate?
I love your videos guys. Brings out the geek in me and makes science so cool.
Thank you! :)
"makes science cool"? science is everything you douche!
why do you put potassium nitrate into the aluminum? can you explain?
+Karkenou It's an attempt to reduce bubbles in the final product.

I was really worried you weren't gonna show us that lathing part at the end. So good job!
Nice, followup video?

not entirely sure a fire extinguisher will help ..at that temperature ... it will re ignite as it burns through things .. best done outside ?
The Kaveman hi
mhmood halak
wow lots of negative comments. I think you did an amazing job.
I am in by no means a profesional, but even with my limited knowledge, I saw so many stupidly dangerous things in this video.
+Izeck Kattz Like?
For one, he pored molten metal into a mold that is sitting on a wodden table. One leak and there would be trouble. Second, he even said it himdelf. The crucibal that was used had holes in it. Third, the shop ios a mess and filled with trip hazzards. There are others, but I won't bother noting them all.
I have no idea what a flywheel is or why this was a recommended video or even why I watched it. But it was very cool.
he's making a flywheel for a internal combustion engine
What did you wind up using the flywheel in?
+Nick Ball homemade internal combustion engine. But then I made a better one. So this one was only used on the homemade ic engine for a few months.
That's rad, what's it power?
Makerj101 ยบบลบ
final product at the end looks very nice, next year I'm hoping to do some ant hill castings and I also want to do a little green sand casting.
+Richard Wheatley Thank you! I really want to do an ant hill! Problem is I can't find any since we don't really have a yard. Mostly woods. Best of luck with your castings!
Got to applaud anyone who gives things a go - but Christ man, you need to respect the temperatures involved. Be careful and get the essential safety equipment. I know there are safety Nazis on TH-cam, but you were seconds away from serious and painful injuries in this video.
+Mavermick1 Maybe... gotta live on the edge sometimes! :D
Not bad. This was worth watching from the ingredients to the finished product.
why potassium nitrate ?
Binds to impurities
Why isn't that making a bang? It is after all the oxidizer in blackpowder.
+Ruben Proost black powder, let alone potassium nitrate alone, doesn't just go bang unconfined like that. the most it does is burn really quickly.
because in black powder, there is a more than just potassium nitrate, you need also charcoal (fuel) and sulfur (to reduce ignition temperature)
Well, lighting a mixture of potassium nitrate and sugar also gives a flash, and aluminium is quite flammable.
Advice from someone who came very close to burning down his house.
If your kiln is sitting on a wood floor or desk, always allow an airgap of at least
an inch under the kiln to allow heat to escape.
Without an air gap, enough heat will slowly migrate right through firebrick and ignite the wood below it.

you could use aquarium sand for ur green sand. it's all the same size and it's so small so it captures every tiny detail.

I used baking soda and borax today and it made a huge difference. I was even able to pull more aluminum out of the dross.
Thanks man...i like ur experiment
