build a foundry and sand-cast aluminum.
Welcome to my first guide! ! ! ! (
We love you, Fenris! You rock!
Give me your socks and let me frantically collect things related to you! ).
Thank you, thank you!
But seriously, I have to go to the teaching office. Please settle down.
In this note, I will detail how to build a simple, cheap, and effective foundry that can melt aluminum.
This foundry can be built quickly with very few tools or money, great for starting metal processingcasters.
I added this to the Epilog Laser cutter challenge, so if you like (
Like you can\'t), please vote.
I\'m your best friend. )
Before I direct your idea, let me tell you how the project is green.
I live in Hattiesburg, Mississippi, and there is no recycling center in Hattiesburg.
The nearest center is Jackson, Mississippi;
About 80 miles away.
No one wants to drive for 2 hours, just to hand in some jars that might be thrown away in 5 seconds.
My friends and I came in from here.
Our friends, family, and even those who just want to recycle, bring us a few pounds of aluminum cans every week, which usually only takes up space in the landfill.
We melt their rubbish, create tools or art, and then we can sell or give away.
Although this casting design pollutes the air with smoke, it teaches us (
Any other initial metal.
Caster who wants to learn with us)
What we need to know is how to build a greener, more efficient design
Burning propane or using waste
Oil as fuel (
Reduce the number of toxic chemicals that people will dump elsewhere).
As we learn how to build a cleaner, more efficient foundry, I will post instructures so that people MS places like Hattiesburg can do their part to save us
About legal issues!
First of all, this description involves fire, molten metal, sharp edges, electrical equipment close to water, burning paint/other harmful smoke, and some other dangers that I don\'t even know about.
If you\'re a disorganized person, you really shouldn\'t try to do that.
By reading this instruction, you agree that I am not responsible for any injury, property damage, personal injury or anything else you wish to sue me, in the construction and operation of the foundry described in the above Instructure, if you follow my instructions, there should be no problem with your safety.
I will do my best to elaborate on the safest approach.
Casting metal can be complicated.
It\'s a good idea to feel it first. Metal-
A good example of what we are doing.

Your tin can cuts a hole in one of the coffee cans for hair dryer installation. It\'s O. K.
If there are some horns that don\'t fit the hair-
Dryer nozzle, my No, my foundry works fine (See pic 2)
With your drill (
Or hammer/Spike combination)
Hole in the bottom of another coffee can.
Again, consistency is not a requirement.
There is an easy way to do this1. Insert hair-
Put the dryer into the air chamber 2.
Place fire room on top of air room
It\'s easy, but very dangerous.
If you push the fire chamber a little, the whole thing will fall over and form a challenge at your feet consisting of hot coal and molten metal.
On the other hand, however, being able to remove the fire chamber from the furnace gives you the advantage of being able to shake out the coal dust that will eventually clog the air chamber hole.
This can allow you to keep the fire burning for longer while melting multiple times.
If you feel that the fire chamber is loose and you can\'t handle it, then you should dig a fire pit and fill it with sand, place the metal stake on the ground and extend along the side of the jar.
This will keep the jar in place but still allow you to remove the fire chamber quickly.
It is important to separate the parts of the can, because they all produce different amounts of scum (
Garbage in metal must be removed)
And should be melted at different points in each smelting.
The 3 parts that must be separated are the top, side and bottom of the jar.
The picture shows my favorite way to destroy cans.
Unfortunately I can\'t get the image annotation to work, so you have to read the program here and follow the picture below. 1.
Cut the jar in half. 2.
Make a crack in the upper half and stick it on the lid. 3.
Tear along the cracks and pull out the siding from the top of the jar. 4.
Make a slit in the lower half of the jar, at a certain angle from the bottom. 5.
Tear as close to the bottom as possible and remove the siding.
If you make up a production line with some friends and one of them assigns one of the steps above to him/her, it will be much faster.
I split the jar into two halves, siding, top and bottom boxes, and occasionally there will be a box that will be used to coat the jar with the top or bottom.
Once you \'ve finished processing the can, it\'s time to get your foundry ready.
After assembling the stove, place a circle of coal at the bottom of the fire chamber (pic 1)
, Then place two coal perpendicular to the ground in the center of the ring, tilting each other (pics 2+3).
This increases the airflow under the tank and helps to heat all the coal and ultimately provide better melting.
The wrong way to do this is to put a coal flat under the jar ,(pic 4)
Block the airflow from the center of the furnace.
Next tin (steel actually)
It is possible to add coal evenly on the sides of the tin at the top of the two central coal until it stands itself.
If you don\'t want to make a mold, just some metal spots (ingots)
You can pour melted aluminum into a muffin jar.
Ingot can be
Melt later if you need metal.
Easy to make sand.
All you need is some sand and a way to design it on the inside.
You can do it with a stick or something, but the result may not be very good.
I think you get the best results when you use a month-like-D pattern on it
In this case, I found some pottery at the flea market.
If you have friends (or friends)
When you melt the metal, they can do a cool design with you.
All you have to do now is prepare your job. space.
Waiting at the foundry for countless possible misfortunes, you can eliminate almost all of them by being prepared.
I have some pictures of my casting equipment here-
Start and run, and some photos of me operating it.
Please note that the wires are far away from the walking space with buckets, so I will not trip over them, water and aluminum (i. e.
On the other side of the walking space.
You need to be able to walk around the stove without hitting anything.
You need them when you need water and mold, but don\'t be too close to you to hit them.
If you \'ve done all of the above, it\'s time to start your stove!
Make sure all your safety gear is in place and then get ready to do some metal at the end-melting!
Put your crucible in half first.
The way they fill the top of the tank, they burn the cleanest, so burning them first will produce more molten aluminum to drown out other tank parts.
Then, ignite the charcoal! ! ! Whoooo! fire!
If you use regular charcoal, you have to use a lighter liquid that can drop onto the hair dryer via the stove, so I only use instant glowing coal in the stove.
Once you think that the coal underneath and around the furnace is lit, start hair --dryer.
Next, you need to add coal to the sides of the Crucible until they form the floor as evenly as possible at its center.
Once the top of the Can starts to melt, you can see the glowing red color of the can, and it\'s time to get to the next step.
I have a few instructional videos to show you, but my mother accidentally removed them from the camera.
The world is crying. It\'s O. K.
The stove is quite straight, though-forward.
What you really need to do is 1.
Crucible filled with aluminum chips 2.
Cooling pliers in water 3.
Let the aluminum melt 4.
Remove scum with metal rods (
Hair floating on the surface)5.
Cool metal rods in water. 6.
If you don\'t have gas, repeat it.
Then, when you feel the hot air coming from the stove hitting your face, you need to hold your breath and the aluminum scraps should melt in this order;
Can be top, can be bottom, then can be side.
This is in the order of metal. to-dross yield.
After the aluminum melts, the scum should be removed quickly, otherwise it will gather with some aluminum and stick to the side of the jar, reducing the amount of pure aluminum that can be obtained every pour.
Here are some pictures of me going to slag.
Also, you have to be careful with the hot tools, not only because they burn you, but also because they burn something else.
For example, if you try to take coal out of coal with tongs
Coal will ignite the whole bag.
When you notice that the light of the Crucible begins to fade, either add more coal to the fire or prepare to pour the mold. The most self-
Explain the steps.
Pick up your crucible with pliers and pour the molten aluminum into your mold.
Its surface looks smooth while the aluminum is still melting, but if you look closely you can see that it starts to crystallize.
Try not to pour out from too high, otherwise the aluminum will crush the details of the mold.
Again, I apologize for the lack of video and I will upload some as soon as possible.
This is a photo of the finished product. (
I didn\'t use enough aluminum):(. . .
To be honest, you know you like this structure, I know you like this structure, and we all know you like this structure.
Why are we playing this game?
Don\'t talk about coy anymore. Vote for this structure!
But really, the laser cutting machine will be used very well.
