Hello!! I am new here. And i am wondering if any of you have tried casting black powder gun parts/ normal gun parts yet. I would be really easy to just cast PLA 3D printed parts. I have the prints of this website: https://www.assra.com/Archivelibrary.htm Its single shot rifles. And i am looking at the Winchester High Wall 1886 rifle, as a concept. I havent 3D drawn the files completely yet. But a few evenings will get it done im sure. What actually made me look into casting is this file "M16 trigger" https://ibb.co/PGMGbqt (Its only there for a month..) And this video convinced me: You can make guns, and gunparts with casting. The thing is. What is the right approach? What plastics are the best? What mould material is the best? Ive seen jewlers investment powder where is vacuum needed when pouring. Ive seen boxes with sand, where the pour is performed. Ive seen hard sanded shell methods. The sanded slurry method seems to be the easiest. You slurry and sand your parts enough times. Burn out the plastic, and you pour with hot slag skimmed steel, and thats it.... But would it have good enough "resolution"? And i dont know what is a good method to heat the steel to the right temperature. Gas, induction??
