It seems to me you are the one full of himself, I answered you in my first sentence. There is a plethora of information posted here that you have not bothered to read, or try to help yourself any, and you then complain when we did answer you, Iron is not a starting point for casting, Aluminum is a much better starting point. which you would know if you took any time to educate yourself, you cant just jump in and cast iron, as John explained its not a skill that can be self taught, and its expensive learning curve. but have a good life,and I hope you dont kill anyone on your journey
