Hi guys,
here I will post about general stuff. All new things I buy, any technique I'm trying etc...
Let's get Started... !
My metal foundry experiments !
First, my equipment !
Some mixing pots
Some siringues, for a precise dosage
I bought high temperature RTV139 silicone from "Esprit Composite"

A Prince August Kit Ladle, talc and clamps

I also had a mini camping gaz heater for the metal.
I did build mold boxes out of cardboard (I don't have legos yet !)
First I tried to mold some conversions of existing miniatures.
I melted garbage miniatures to get the metal I needed !
As I didn't have any clue on "how to do it" I made several mistakes. Resulting in some problems !
(I'll just post the mold, erase the photos if it seems too much identifiable !)
So I identified some problems I thinks can be solved easily : next time I'll :
- pour the silicone of the mold in an angle so it doesn't give so much bubbles.
- put some release agent before I do the second part of the mold (I had to tear it in two pieces afterwards ! Hense the "multipart mold ^^)
- I won't heat the metal so much it changes color... ^^
The result is quite good but has some quirks. I won't post it because it might create IP problems.
For the "too much heat", I bought a LEE PRECISION MELTER

As you can see, the international version of the melter does not include a plug. So I have to buy a 500W plug. I am also going to include a switch to make it easier to use.
and a LEE LADDLE

My few questions :
- I have a problem cleaning the laddle. How do you do that ? I becomes very dirty with metal residues.
- Can you do metal casting in a pressure pot ? Will it increase the quality of the casting ?
Anything else ?
I'll post the next stages in a near future
