I'm done drinking around a lathe and I have some thoughts. Not about safety, exactly. I have learned to shake the spook of sneering at hands in pockets meaning laziness - it's merely safety in the workplace.
But I do have some questions that I've had a decent amount of time to opine on, but to no real affect. To be blunt, I've been wondering for the sake of just writing, whether or not it would be feasible if the power went out for too long, for someone to actually reproduce military arms. Could be any reason, really, foreign states using CBRN, or sabateur attacks, or WEF policies leading to an authoritarian government or lack of any government at all, how would weapons made after that event look, at best?
I've taken the AR-15 as an example, or a challenge, really, to reproduce with just scraps. Melting down things like hand tools, common recyclables, and components ripped from industrial or automotive machines. You might be surprised at one of the two, just how available they are, or just how high a temperature you need to reach to smelt them to the proper alloys.
But one thing I fail to see anyone considering is even if you can extrude a piece of aluminum you've melted down from cans and copper to achieve a 7075 alloy content, how fucking hard it would be to actually do a barrel. It's one thing to use a hydraulic press, but see pic related and I think you may have questions about how to make that machine. I'll keep those insights to further PrepHole questions.
But the main topic of this thread would be what are the common difficulties people would run into should there be a great reset? What were the most prohibitive innovations in modern firearms people just don't understand? We can't go out there and just make gucci guns without special order, if you don't have specialized tooling too.
