Also, diecast joints are garbage. They ALWAYS get worn because soft metal on soft metal is shit as it is but it's even worse when they can't even get their tolerances right.
The proper way to do durable articulated joints is polished metal on constrained nylon. It'll be much tighter, won't get loose (for decades at least), and it'll be smooth as hell.
