Do any metal casting? - Page 3

Right then, this brick which I now believe is the wrong one.
Then my 3D printed helmet which I plan to make in aluminum...

Ok I will explain. I am a hobbyist who is building an exoskeletal armour based on the War-Machine but redesigned with the focus of a full range of motion with lights sounds and servo motors. This will be in steel, aluminum and titanium.
I am learning Hammer forming, Metalcasting, Machining.
I have read up on kinetic movement, mechatronics and studying engineering in relation to this.
I have working theories on the glove: open-closed mech.
The abdominal, boot, helmet mech.
I need to cast some materials as I don't know how else to make them.
I have been at this for some time as I have been in the research and development stage of my build...

Even more pics...

Awesome kiln man!!!! Your plan on casting the parts to make Iron man is so cool. What are u going t make it out of?
