Casting an Aluminium Flywheel Using Green Sand Open Mold

I think u might consider buying bigger memory Card !!! Maybe 100 GB 我只是從一個不同的視頻複製了這個評論，我希望這意味著好的東西

Jesus, the negative comments from virgins without the fucking balls to make their own videos is astonishing. There is one HUGE downside to the internet, the dickheads who use it.

What is the shrinkage percentage?

Use borax

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.

Not bad. That pretty good.

dok buat sempoi

ag wat natang pa woi vdeo trgantung ni hram x pham

Use sea salt

he wont live long. he s an id10t!

what was the white powder you put in to scoop out the slags? for what i figure out that powder helps to get the purity stick onto them to make it easier to take out the slag

Not bad. This was worth watching from the ingredients to the finished product.

where did u get the idea that potassium nitrate was used as a flux ?? i have heard of borax and some rosins ..

oxides will formed in casting due to open atmosphere ......video is good....

Excellent brother!

Good

que arena es esa que se usa para hacer los moldes??

BORAX

glad to see someone of the younger generation carrying out such projects,keep the flame alive!

随分と精度の低い鋳型だね。

Worst video ever I watched

Prova com

did you use a compressor tank cut in half for a crucible?

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.

Ain't it that green sand a little brown ish ? ... :-)

More serioulsty, what difference between red and green sand ? ...

And, thank you for the video !

Buying an equal piece of aluminium is much cheaper and you have quality control !

Do not try to "invent the wheel" again

i bet you dont even have safety glasses

this set up is a saftey violation waiting to happen.

Question?...what does the nitrate do to the aluminum?

Oh yeah very smart to have a bic lighter next to your forge, with a leaking crucible.

Do you think the iodine in table salt has an adverse effect?

I hope you dont do that stupid beating in next video. I liked in starting but I stopped that beating sound was unbearable.

Would this same method work for a releif sculpture? Also can copper work? I wanna do this to a lifesize releif. Does anyone know if it will work?

very gau

reason why kids these days burn shit down by being fucking idiots

Sir aluminum ko galane ke liye kao kaon si chijo ki jarurat padti hai puri jankari bataye hindi me

red glowing aluminium - it is allready liquid then a longer range of temperature - is in contact to water an explosive!!!!!! Take care!

why all those dislikes :(

Rock on dude! You remind me of me15 years ago lol

that brick smelter ! ❤

What kind of powder you used to mixed with? Thanks before

Take care guy!! It`s dangerous working with cast aluminum!!

ماهي المادة الذي اضفت للالمنيوم البودرة البيضاء هل تخبرني

You are taking a way too high risk here! Get some sand on the floor, and do it the safe way! Put both the furnace and the mould on the floor, and use SAND to put out any fire! It will be much easier to clean up afterwards.

thats what she said

Yeah, stick banging on a casting flask - that’s not a crucible - crucibles are made from high temp ceramic material. Put the camera on a tripod. Craps I’m sea sick from the bobbing around. Watch something else. 😂

where to find this particular sand ?

👍👍👍👍👍👍

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.
