FOUNDRY CASTING Making a Sand Mold part 1 TUBALCAIN

[CladCoin]

Interesting name. I have a video, here on youtube, where I found a penny, while metal detecting, that had been put in a press and has a Tubalcain symbol imprinted on it. Evidently it used to be a common item that was made for certain Freemasons. I have a question... where does one purchase foundry sand for mold making? Thank you for your time.

@CladCoin Do a google search for petrobond sand. You will find several sources

That was excellent most informative video I have ever seen on this subject. I wonder if you could mention a little more about the parting sand.

thank you very much for taking the time to keep this art alive for us.......I am interested in making a little home foundry also..........

Very good instructional videos. Good thing I am retired, I may be watching all night. You've got me interested in a new hobby.

now understand, here called the oil burns, it turns black, many use as fuel to the burner ...

you think that using oil is better than using water?

what's the difference?

[mrpete222]

There are 2 kinds of foundry sands. Oil bonded and waterbonded. I use oil type. I am using Petrobond brand sand. It is a mixture of fine white silica sand, 30 weight motor oil (without detergents), the Petrobond powder (a specially modified clay), and a splash of liquid catalyst. The mix is prepared in a machine called a muller, which stirs and mashes the sand.

I'm keeping a home foundry, I want to make a living working with casting ...

I make signs for residential addresses

[eddragon76]

am of Brazil, do not speak English, the translation of google so it is understood that detergent ...

not oil?

[mrpete222]

No--it is 30 weight motor oil. detergent is just an additive to most oils.

[Mcgheekevin1981]

@mrpete222 What brand and where do you buy non detergent. i have been searching forever for this.

[mrpete222]

@Mcgheekevin1981 Any farm store.

[eddragon76]

what kind of oil you put in the sand?

[mrpete222]

30 weight non detergent

[eddragon76]

hello, the compression made up on this side does not cause vibration damage to the mold?

I appreciate your interest.

Thanks Tublacane! I've known about sand casting for decades and even have a friend that has castings made for him, but this really answered some key questions about the materials used to do the process. Very helpful!!

Can't wait for the rest of the series.

Most interesting so far, using a different sand to what I am using (green sand, sand and bentolite clay, water)

The oiled sand would not dry out so much like the green sand I would imagine, I have to keep my sand in a closed bucket to keep it moist.

[mrpete222]

Thanks--the petro-bond sand is great--it always ready to be used.

[baconsoda]

This is super. I have never cast anything and I probably never will but I love to see processes.

Thank you for taking the time to show this,

Brendan

[mrpete222]

Thanks--I'll keep them coming.
