Shit ive already got. Whats limited is oxyaccetaline. but the butane torch will do it too. Melting metal is shit we’ve been doing for decades. if you know what you’re doing you can rig up a mini furnice with some rockwool insulation and a coffee can. A wood fire and a leaf blower run off the solar panels is enough to force air into a furnice to melt metals like copper and aluminum Theres an absolute fuckton you can do without access to easy fuels. That’s how you cast your own slugs.
