Metal Casting at Home Part 39, Cylinder Casting with Core

[@Bobcat1963]

Another successfully pour myford. Love watching you do metal casting. Please keep posting your video as the world will be watching you. Great Job!

[@raven92562]

You make it look easy. I'll be glad when I can do it this easily. Learning, but cast my own cope and drag locators as well as a ramming tool of Aluminum. Next time, I start casting drag and cope pieces for permanent drag and cope.

[@RubSomefastOnIt]

HOW DO YOU... like answering the same questions over and over in each video you make? lol love your videos got me started casting, as a machinist it opens up so many doors.

[@TheHelado36]

This looks so fun !!!!!!!!!! The furnace looks like an expensive item !

[@Itsbigpitch]

Tiny ones like that are a few hundred. The huge 1000 gallon ones I use at work at 20-30 thousand a piece and is like standing next to the sun.

[@abilalpk]

Excellent work.

[@barumman]

Nice job, you make it look easy. Best wishes.

[@attiksystem]

I love your security shoes! :)

[@myfordboy]

They are quick release footware,easily removed in case of metal spills !

[@jonyjbara3763]

You are a professional marvelous work I love this job...

[@eagle159sam]

Justo lo que estaba buscando. Excellent job.

[@1ramus1]

Great job.

[@stevehammel2939]

Amazing

[@BSCequalBOS]

Nice video as always! Just one question, what happens if you just let the flask with the greensand sit for 2 days and then use it for pouring? Will the mould be ok? I am asking because i think, maybe you will make one mould monday and tuesday the next one and maybe you will start your furnace on wednesday.

[@myfordboy]

In a industrial foundry they will make up the moulds one day and pour the next. I have not needed to do this but should be OK if the mould is closed so the sand cannot dry out.

[@solartubewell5609]

very good

[@MJB8765]

Hello, thanks for your great video,i have a question, how did you put core part in the mold without it touching the mold? The core part should be at a equal distance from the mold surface.

[@myfordboy]

I asked this a lot so have an explanation here myfordboy.blogspot.co.uk/p/metal-casting-tips-and-faq.html My next video will also show a core being located and I showed some other methods in this video kzbin.info/www/bejne/qXqlgoqeYpaYj80

[@hoppercar]

Your flask pins aren't long enough....if you have a core sticking up higher, than the pins are long....you could hit the core when closing the mold , and wreck it, before the pins engage

[@NGinuity]

Did you make a new smelting furnace at some point? The square add on looks a little different than what you had before but that may just be me not paying attention.

[@myfordboy]

I have 2 furnaces. This one is a commercial one. It's the same size and performs the same as my home made one.

[@ahmadal-qudsi4913]

Hello I want to thank you for this beautiful passages and I have a question for you ... what this white material developed by the smelting of aluminum ? And what her full name ? What are the benefits ? I'll be happy when I see your reply ... Thank you

[@myfordboy]

+ahmad al-qudsi Do you mean smelting or meting?

[@CompEdgeX2013]

Dang, I tensed when you dropped the half flask...Looks good in the end though. Video quality is really good...new camera lately? Cheers Colin

[@myfordboy]

Just shows how strong the mould is. Same camera. Cannon SX220.

[@aserta]

It's on the KZbin end. The compression works in mysterious ways. So mysterious not even KZbin employees know what it does.

[@martinherbig7723]

Hey, got a question about the degassing... what are you blowing in the molten material with that tube? is it just to mix in the sodium carbonate?

[@myfordboy]

I'm not blowing anything. The sodium carbonate is wrapped in foil and plunged to the bottom where it turns to gas.

[@martinherbig7723]

Thanks a lot, ill try that! ;)

[@aserta]

Your furnace, is it made out of a compressor by any chance?

[@myfordboy]

The one in this video is a commercial one by Kasenit. My earlier videos show my home one which works just as well.

[@aserta]

myfordboy Ah. Thanks for answering.

[@loloaqici82qb4ipp]

What is there not to like about a job well done?

[@Itsbigpitch]

When you do this on an industrial scale, pouring 80,000lbs molds everyday for 10 years, it looses its charm. I still enjoy manufacturing something each day though.

[@funkyole1125]

is there a reason you keep the core sand out of the casting sand?

[@RubSomefastOnIt]

it stays solid and wont mix back into the reusable casting sand.

[@myfordboy]

I don't want the sand to mix as it is different. A little bit won't hurt though.The core sand can be used again if it is thoroughly washed and dried.

[@DavidWahlstrom69sins]

Can you use clay instead of sand?

[@Itsbigpitch]

You could but removing it after the cast has hardened wouldn’t be as simple. In larger scale operations clay can be used and removed with heavy tool and machines but at home might be more effort than its worth to remove it.

[@Hoksmur]

Sorry, what is hydrogen at 9:13? I didn't catch. Where is it use or whrer can I give it?

[@myfordboy]

The metal absorbs hydrogen and can make the casting porous if not driven off.

[@Speeder84XL]

myfordboy How can it absorb hydrogen? Do you mean oxygen? Otherwise - where does the hydrogen come from? Maybe the propane if there is not enough air (but that's clearly visible because carbon will be realeased as well and black smoke and soot will come out from the furnace). But hydrogen doesn't react with aluminium anyway. The air is full of oxygen on the other hand, wich form oxide with the metal and can also make it porous. Worst thing is when melting thin metal stuff with a lot of air trapped in it like cans or thin wires - in those cases it helps to put some combustible stuff like a small piece of wood in the cruicible wih the metal and put a lid on before heating it. That "eat's" most of the oxygen away before the metal melts.

[@myfordboy]

Ride84XL I don't know the chemistry but it is well know that aluminium absorbs hydrogen when melted and that's why it is degassed.

[@cannibalholiday]

Ride84XL Look up "Hydrogen Gas Porosity" on Wikipedia for a good explanation. I'd link directly to it but then KZbin might eat this reply :)

[@odiekokee]

how do you make your mold patterns?

[@myfordboy]

Its just woodwork. I have a few videos on pattern making. Metal Casting at Home Part 15. Pattern making, start to finish. Metal Casting at Home Part 22 Flywheel Pattern Making & Casting. Metal Casting at Home Part 8 Pattern Making

[@odiekokee]

myfordboy Thank you. I just hadn't looked far enough.

[@karimnouioua7913]

how the first and second patern are made

[@myfordboy]

This video shows ow patterns are made. Metal Casting at Home Part 22 Flywheel Pattern Making & Casting.

[@sionmr2]

Блин, кто-нибудь, подарите ему уже новые ботинки!

[@fpego]

10:15 flux???

[@myfordboy]

I always answer questions but it's helpful if you can ask them in a full sentence to I know exactly what you want.

[@myfordboy]

Flux is sodium carbonate.

[@fpego]

What is the sodion carbonet?

[@fpego]

What is the sodium carbonate?

[@fpego]

What is flux?

[@stevefiveoh53]

Not bad but sorry its a bit amateur in terms of technique and speed.

[@AndyGuinan]

+Steve Mason that's why the series is called "metal casting at home"...can't expect someone to have a full foundary in their back garden haha I thought the techniques shown were really simple and easy to follow and I like how he explains everything in a lot of detail...not once does he claim to be a professional but I personally am inspired by his work which is probably one of the reasons why he filmed the process and uploaded it for others to see

[@stevefiveoh53]

Noted Andy. Thanks.
