Yeh, did look. I’m getting closer to 3D casting. Right now I just make a little for handprints my daughters make.

I am using sodium carbonate ( Washing soda). Sodium bicarbonate (baking powder) is a differant animal. Check out wikipedea.

I have sodium bicarbonate. Is there a diference? Your video states carbonate.

You need sand from a foundry or make it by adding 10% bentonite to regular fine sand.
If its sloppy its too wet.

How do you get the sand. mine was coarse and all I could do is make sloppy hand casts with my daughters. I’m wanting to move up in the casting world.

My video number 9 shows the furnace construction.

link on the right.
This is all I have as it was made a few years ago.

Do you have a video …
Do you have a video on you made the home made furnace!. This video is great. Videos is much better than reading from a book.

nice vid, wot is it exactly?

It depends on what …
It depends on what kind of sand your using. There are some kinds of casting sand (or there were…) that you simply added a small amount of oil to in order for it to hold it’s shape.
That was 20 years ago, so don’t hold me to that…

Brilliant video!

Does the casting affect the sand in any way to prevent it from being reused?

That is really good! Thank you so much for sharing. Interesting stuff.

Have you had any …
Have you had any problems with your aluminium castings versus the cast iron of the originals? Are there any strength issues?
I assume you use aluminium due to its lower melting point.
January 2nd, 2010 at 4:56 am
cast aluminium is a …
cast aluminium is a better grade than the extruded because extruded is alloyed with other metals/chemicals to improve the different required properties of the structure (resisitance to warping , tearing, integral strength etc) castings rarely need this “boost” because these problems usually do not arise from the thicker, sturdier shapes formed by casting

Interesting. I only …
Interesting. I only ever use metal that has been cast before so have not encounted this. The SS crucibles do eventualy fail , but they are cheap.
January 2nd, 2010 at 4:56 am
I have found that …
I have found that when I melt things like aluminum extrusions (which I think are close to pure AL) it will eat through SS after a few melts. With cast AL the SS containers last much much longer. I’m sure there is some chemistry behind this.

you know i really dont know what any of this is(maybe because im twelve) but for some reason i think its really interesting to whatch. my dad would probably know more about it though.
