Sand Casting Mould Making - no sound

[TheNessaNow]

how can i make home made sand casting sand? I cant seem to find powdered clay, were can i get it?

[TheStarChamberMusic]

Way more complicated than needs be.

[tarekno3man]

something is wrong the box is too big of this model,and why do u do 2 holes !!! u can put 1 hole and don't compress a lot but it is good job :)

[eclipzetint]

my speakers aren't working so I thought you were real good 

[nikhilkash92]

Excellent video! you demonstrated clearly thanks!

[nattsurfaren]

1:30 dropped chewing gum in mold.

[alecz182]

[camParduuu]

looks fun (Y)

[ponytang84]

stricle= strait edge

[ponytang84]

nice vid, and using some proper turms awell:)

[HakemShah]

Awesome! Thank u for posting :D i understand sand casting now.

[captmicha]

Can't you just mix regular, fine grain sand and oil?

[kumanosukeZZ]

this is way better than the previous video which had loud music playing in the background and no narrator

thanks

[thegreatwoodlife]

What I don't see many people doing is making clay molds, kiln the clay, and keep a permanent mould to use. It takes a lot longer, but well worth it.

[itallian59]

Well u at very talented I have to say and maybe if we become friends on YouTube we can share tips!!!!!!!!!!!!!!!¡

[halfmumi]

where can i get "parting powder"? Talk powder or chalk works fine or not?

[Truthhurts3pm]

@halfmumi Talk powder aka baby powder

[001FJ]

Thank you very much. We are studying this at university but it did not make sense to me until I saw it here :)

[dwilmer7]

1974 - 1976 I did this a million times, I loved the skill involved. I left the job due to too much smoke (LOL) but it is really a skill! Thanks for posting this. Regards.

[Avnsbol]

WTF?!

[pattyricks18]

is the sand reusable?

[laztom14]

nice video. thanks

[kk979]

Thank you for the video, the steps are very clear and helped me very much in understanding sand casting.

@slome815

well maybe with contact with direct liquid water but the molds made from green sand there is no problem at all with =) tho they dont have much water, but been tought that if you pour brass or iron into a green sand mold bound with bentonite and water you have an explosion to wait =)

[sys2]

fyi keneyed209 molten aluminium does not make a steam bomb when contacted with water, tho cast iron and those higher melting temp metals does =)

[slome815]

@sys2

alluminium does that too.

the only accident I ever had with molten metal was with Tin (melting point around 220 i think). there was water in the mould (not a sand mould) and all the Tin blew right out the mould into my face.

[madatiza]

Great job jenner keep it up lol

[abeaaaa]

This is very bad moulding, i honestly think a monkey could do a better job, or George Roberts at least.

[ramjam25]

can i mix oil and sand to make petrobond sand if yes whats the ratio?if not where do i buy it from in uk?

[EggMcMffn]

why make such large channels?

[ramjam25]

so the metal does not set in the channel.

[Topakeeper]

si vos sos moldeador yo soy astronauta esa pieza no se funde asi.Esa pieza mas de 3 minutos no se tarda,si trabajas asi te vas a fundir

[gtobin212]

this is terrible;) lol

only joking jenner, its fabulous!!

[speakersound34]

reali reali helpful fankkooo

[ezzat47]

for parting powder ,, i think we can use 200 mesh (grit) silica sand, its like flour or powdered sugar.

[Kevinjonas7890]

im confused?!?!?!?!?

[jaiszos]

What can be used as parting powder?

[jst2k09]

graphite is excellent and won't readily absorb moisture from the sand.

[Ianwoodcraftsman]

The sand looks like it's bonded with Petrobond, which doesn't use water to temper the mix. If so, oil is used instead; approx 10-30 SAE, detergent-free works best. Petrobond is made by Baroid in USA and is sold world-wide. Apparently you can get it pre-mixed with sand in UK

[northgatetechnology]

Not sure - something to do with molten aluminium and too much water content not being a good mix - - best place would be to check the H&S data that your LA supplies. We find it much easier because you don't have to worry about mixing and getting the consistencey just right.

[lilg606]

hey this is a great video. but i think you have to much water/clay in your sand

[northgatetechnology]

Thanks for the comment but there is no warer in the sand. It is oiled sand. Using water in sand in schools hasn't been the norm for a while because of the safey implications and getting the correct water /sand content.

[lilg606]

What are the implications? my school uses water in our sand and I've never herd of safty problems. it is hard to get the water/sand mixture right but we have large automated mixers so it is easy to correct the mix if me mess up

[lover40x]

thanks for your video.

[fedaikn]

i would appreciate if someone posted the composition of green sand, or even better, a way to make your own at home.

ich wäre dankbar wenn jemand die zusammensetzung des sandes verrät, oder noch besser, wie man den selbst zuhause machen kann

[northgatetechnology]

The sand we use is called petrabond sand and is oiled sand. It is available in 25Kg bags from suppliers in the UK for about £25

5. Unterkasten wenden und obere Modellhälfte, Einlauf- und Speisermodelle für den Zulauf auflegen.

6. Oberkasten aufsetzen

7. Wieder Modellsand aufsieben und andrücken.

Eingusstrichter herrausschneiden.Einlauf- und Speisermodelle herrausnehmen.Und Oberkasten anheben,wenden,absetzen.

8. Form verklammern.

9. Form ausgießen.

[hindustanboy]

1. Modellhälfte auf Formbrett legen und Unterkasten aufsetzen.

2. Modellsand aufsieben und andrücken auf Modellhälfte.

3. lageweise Verdichtung des Füllsandes

4. überstehenden Formstoff abstreichen

[hindustanboy]

Er hat bis zur Hälfte alles richtig gemacht,danach jedoch wär ich anders vorgegangen. Denn die letzten Schritte sind aufwendiger:

also hier die Zusammenfassung,die am Ende etwas ausweicht,von der Methode,die hier dargestellt wird:

[SKarmytech]

Wow this tutorial helped alot, as i'm still a begginer in metal casting and i'm still building my own homemade crucible furnace. You should think on making a picturized tutorial like this one on the Web, people could then downlaod it and it would be even more helpfull.
