Metal parts cannot be formed in a Part Builder. Crafting a metal part is a 4step process. Create a Pattern of the desired part in the Stencil Table. Make that part in the Part Builder. Place the part in the Casting Table and pour either molten Gold or molten Aluminum Brass on it to create the Cast. 2 Gold Ingots or 1 Aluminum Brass Ingot are ...
