Metal Casting at Home Part 3. Backyard foundry

[@dustyflair]

YOU ARE ONE BAD MAN!!! I love your work. As someone stated you make something that is not very easy look like you are riding a bike in the park! Keep up the good work!!!

[@TheLatchford]

Leave the lad alone,he is doing his own thing and trying to share it with you all.What is the problem with you all.I think the guy is brilliant .

[@Metalstacker]

I watched it twice now and now I understand what you are doing and why thay loose piece is there! Great video!

[@myfordboy]

@fly2000jtb The "locks" are plastic blocks with a locating pin to align the the 2 halves. The diagonal braces are there to reduce the volume of sand I need to use.

[@myfordboy]

@spyderz1303 I use 3/16 steel rod for the pins. Its the clay in the sand that holds it together.

[@myfordboy]

@kaningraff I haven't tried this myself as I have the real stuff but a lot of backyard metalcasters make their own by adding bentonite ( fullers earth) to play sand. It needs to be mulled ie rubbed together so the bentonite clay coats the sand. Around 10% is added to the sand.

[@Metalstacker]

Wow I need to watch this again looks a bit difficult, but I think I understand. That casting sand looks ideal!

[@myfordboy]

@Dach101 Pattern is made of wood as shown in part 8 video. A smooth finish to aid release from the sand.

[@myfordboy]

@kaningraf Correct . You will need to grind it down into a fine powder.

[@myfordboy]

It was put there to stop the previously cut feeder filling with sand.

[@BITTYBOY121]

Thank you so much - Watching this vid just helped me solve a problem i've been facing with a wooden patten for a mould to make a brushed DC perminaent magnet motor end cap (65mm dia by 35mm deep), the design has 2 x 18mm round bits that stick out on both sides where the brushes/brush holders will be - not i know not to glue these on with PVA!! - but to screw them in place so i can remove the main body of the motor end cap and withdraw the two 18mm pieces! *thanks!*

[@myfordboy]

@TheReaperofthefallen You need moulding sand from a foundry supplier or make your own from playsand and bentonite clay.

[@DavisOffGrid]

myfordboy... you are simply a bad a**. I've been studying this stuff for years and have so many ideas. This is the first time I'm come across your videos, but holy geez i wish i had your talent. i have a ton of projects in mind and if i could pull off what you do, I think i could make a go of it building my own products. please keep posting and i'll keep watching and learning. i just build all of the necessary equipment i need to do this. i'm working with green sand, but hopefull can pull it off

[@randomtux1234]

@myfordboy fantastic stuff, the flawless process, the no-extra-words presentation.

[@myfordboy]

@MrLeonard55 If you meen the small tool for cutting the ingate, they are used by artists and can be bought at an art shop.

[@lawrenwimberly1677]

anyone with an inkling of how to do these things don't need a verbal dialog: anyone who hasn't a clue ought not be attempting this in the first place. WATCH what the man does... Been watching his vids for a year, and while I KNOW how to do this stuff, I still find useful tricks in his vids.

[@berniecarlin18]

theres so much to learn here - i wish so much of it wasn't skipped over.

[@kerimil]

damn dude - you're awesome... I've seen some of your vids and I can tell it requires lots of knowledge and craftmanship... kudoz!!

[@myfordboy]

The brown object is the core. This is made from hardened sand as video 5. After the metal is poured the core can be broken out and this leaves the hollow innside.

[@myfordboy]

@lest128 You need a clay bearing sand.

[@myfordboy]

The feeder and riser are long to give pressure to the metal so it feeds the mould as the metal cools. The riser is not essential on a small casting like this It's more of a vent so was made small. Also I did not want a large sprue diameter to cut off but wanted to retain the cast finish on the part.

[@wackedoutdude]

Casting is quite a complex skill i envy you. It must of took ages to get this good. Keep up the good work.

[@jeniajuk]

Хорошое показательное видео . Приятно смотреть . Большое спасибо автору и низкий ему поклон.

[@myfordboy]

@fly2000jtb My sand is water bonded no oil required.

[@liljohnnotbigjohn]

subscribed. You have an excellent, informative channel.

[@barumman]

First class, you make it look easy.

[@AgentJJ22]

These videos are GREAT! Can you also Talc the part of the mold that touches the sand to ease the removal?

[@f.demascio1857]

Yes

[@myfordboy]

Yes a coin. Hard to put a price on home build furnace as it depends on the cost of materials in your area and what you may have already. It;s quite possible to melt aluminium with a large torch and stainless container, you waste a lot of heat though.

[@anasanas-ky5qm]

myfordboy how to make sand casting

[@spyderz1303]

What do you use for pins in the modesty blocks you use to line up the two halves of the moulds? Does the sand have oil in it or some other binding agent? It seems to stay put when it is compacted into the moulds.

[@naphom]

@chopperboy25 - Some cat litter is made of either bentonite or attapulgite clay... You just need to crush it in order to use it. I guess it would be easier if you could buy it in a powder form from somewhere.

[@myfordboy]

@noxnflame Greensand came from a foundry. I haven't tried making any.

[@myfordboy]

You would need to reach 1350 deg C to melt iron.

[@myfordboy]

@dirtydirty505 So do I. Myford is the make of my lathe.

[@myfordboy]

No. The meta flows in the cavity left in the sand and forms that shape.

[@myfordboy]

@tyler031734 I put a coin over the hole when the top flask was rammed up. Forgot to mention it.

[@hopeinflames3449]

I found something that just said find a strong steel barrel or other container, cut out a hole near the bottom for air intake hooked up to a blower, and use a bed of charcoal as the heat source.

[@BossYeahTheBoss]

Thank you Sir, you're simply outstanding!!

[@myfordboy]

@KrisKustomPaint No , its just my hobby.

[@paperjack93]

@myfordboy Where did you get foundry sand ?

[@pedrovargas5031]

Thanks for all your incredible videos. One question could you tell me please what kind of material do you use for the core when you foundry one aluminum piece ? Thanks.

[@myfordboy]

A core would used when the inside of a casting needs to hollow. The core is made of sand and held together with a binder, it can be baked or gassed to achieve this.Examples here Metal Casting at Home Part 33 Sodium Silicate & C02 Core Water Tank and Metal Casting at Home Part 5 Backyard Foundry Core Making

[@diddle228]

Do you ever end up melting down something you have made in the past to make something new? If so that would be pretty cool to see a video of the whole process of re-melting an old cast. Thanks!

[@myfordboy]

Sometimes the casting will not come out perfect and then it is cut up and remelted but I don't need to remelt something I have already made up into an engine.

[@diddle228]

Sweet stuff man I just found the playlist for all your hit and miss engines and I'm watching your LTD Stirling Cycle Engine Free Plans build right now. I'm gonna have to give it a try. Very creative. Keep it up.

[@myfordboy]

@bearpatch626 I don't know what that is.

[@tobin989]

how come your riser was that size? is it even necessary being so long and thin, shouldn't it be wider at it's base?

[@jsrnf]

What are the clips that you use on the side of your boxes ?

[@ampeyro]

why didn't you use the lost wax with that?

[@zedi412]

how did you make that core what materials and how did bond together ? really curiouse ty

[@Dach101]

the pattern is wooden? what do you paint it with to aid release?

[@KrisKustomPaint]

Very clever! Are you a foundry man by trade?

[@MrLeonard55]

Where do you get the small tools?

[@myfordboy]

@chopperboy25 Try a pottery supplier or Ebay

[@xDhimAgainxD]

Can you, instead of melting aluminium melt charcoal to produce molten iron?

[@noxnflame]

Where do you get the green sand or did you mix it? If you mixed it what ingredients and how much? Thanks!! Great vid

[@xarlock667]

So I have tried making green sand... I used PlaySand from Lowes, and repeatedly sifted the hell out of it to remove large pieces, then I added water. I made a mess that fails to do anything but piss me off. I tried using it in lost foam casting, and again failed, as the sand keeps collapsing into the foam. It is infuriating, as I need to cast a feeder for a .22 and cannot seem to make it work. Any advice?

[@backyardsounds]

Love the videos...

[@JonSpink]

@chopperboy25 You can buy it as cat litter its very cheap for a big bag. Make sure you get the clay stuff not the fancy stuff.

[@lest128]

would sand or clay work for molding

[@beneneto2008]

Muito bom seus vídeos, estou aprende a cada vez mais quando vejo eles.

[@papakelt1]

myfordboy Could you explain the purpose of the riser? And am I correct that the role of the feeder is to allow the molten metal into the mould?

[@f.demascio1857]

Besides proving a path for the molten metal, the riser also provides "head pressure" for the shrinkage that occurs during cool down.

[@myfordboy]

You have to make it from wood. please see my videos on pattern making.

[@kevinbrenton3036]

Very talented .

[@bearpatch626]

would clietchie clay work?

[@pauldude000]

@xarlock667 You need to add fine bentonite clay to the mix (10% or so) to make the sand adhere to itself. Otherwise it will fall apart like you describe.

[@AMANSINGH-mp2fx]

sir may i know what is that black powder thing

[@myfordboy]

@stradle124 I'm in the Uk so cannot help.

[@tobyw9573]

The white, rectangular links on the screen are sending me back to the previous video, not the next one as they say. Same problem with previous link. Does this problem affect all videos? Otherwise, super videos, cannot thank enough!

[@myfordboy]

That's intentional on this video. It was taking you back so you could see how the pour was done. If you want to watch the series in order here is the playlist kzbin.info/www/bejne/f4q9gIeqbt-HrJI

[@TheReaperofthefallen]

what kind of sand do i need for this and where can i get it

[@thangquocnguyenmdp]

The best engineering minded

[@myfordboy]

Sure can.

[@t5239857289578947594]

@myfordboy Great, there's a foundry supplier at every street corner. My bit of humor. I'll start looking.

[@hatejewsand2a]

You are wonderful...

[@myfordboy]

Part 5 video in this series shows how its made. I am now using a different method and that is shown in part 30

[@ianrodriguez3944]

what is the black powder material and if it's something special where can I get it please and thank you

[@myfordboy]

It's greensand. I only had a small amout of this blacl sand but now use Bromsgrove greensand from artisanfoundry.co.uk

[@altnrgaccount5466]

Is there any alternatives to using baby powder to keep the two sides from sticking together?

[@myfordboy]

What's wrong with baby powder , easy to get and cheap. Calcium carbonate is the profession material for this. Try chalk powder.

[@altnrgaccount5466]

There is a lot of controvercy surrounding it suggesting it is dangerous due to its tiny particle size.

[@myfordboy]

I'll take the risk.

[@altnrgaccount5466]

worse things happen at sea. :)

[@myfordboy]

No. Nobody can melt charcoal to make iron!

[@danielk1000d]

Hi, how are you? I'd like to know how to prepare this type of sand. What should I use?

[@myfordboy]

kzbin.info/www/bejne/o3-nnZx6gK1qfsk this is how i do it.

[@scottmasterson2594]

What is the black sand made out of??

[@myfordboy]

The sand is known as greensand. The stuff in the video is a foundry product. read more about greensand here. myfordboy.blogspot.co.uk/p/greensand.html

[@juicebox30961]

Very cool

[@larz0001]

@chopperboy25 try the grocery srore and buy kitty litter, or a pet store,, kitty litter is bentonite clay you just have to grind it into dust

[@myfordboy]

I saw them off!

[@myfordboy]

It is sand. Known has greensand it has a clay content to hold it together, More about greensand at myfordboy.blogspot.com

[@Dach101]

@myfordboy thanks, I should of waited with that question until I had seen all of your vids :)

[@myfordboy]

Special foundry sand.

[@tylerkrug7719]

That's a nice screwdriver, wiha right? Expensive little things, lol

[@1220975]

So...........What is it?

[@MrLeonard55]

Thanks.

[@scottmasterson2594]

Thank you

[@Artines999]

♥.♥ Thank you.

[@tobyw9573]

Ipad air, latest upgrade, v. 11.2 I think.

[@myfordboy]

Talcum powder.

[@camelazo]

4:11 unos pases magicoss!!!

[@thdmtr]

coooool =]

[@tyler031734]

Okay, wheres the trick? When you separate the cope and drag there's a slug of some type covering your pour spout. You didn't put it in there in the video. lol

[@iankleinschmidt712]

Magic

[@bearpatch626]

spelling is proboly bad.... its a clay commonly found out here iin tx

[@mackemcabbie]

Hi could you please make me an fa cup trophy

[@reapersoulman]

the only complaint I can gave to these vids are that you don't speak during them you seem like you know alot you really should tell us some info while you work or over dub the video later thanks for all the help by the way.

[@synapse131]

There's no iron in charcoal. Charcoal is added TO iron during forging to add carbon, which then forms steel and there are many sources of iron. In medieval Japan they used black sand from river beds and in medieval Europe they often used iron rich peat from bogs. These materials are added to a high heat furnace and the impurities mostly burned away. It would also require greater heat than aluminum. Correct myfordboy?

[@Gr8Success]

i hear frogs
