I clicked into this thread expecting hobbyist/hacker machining with steel and brass and aluminum, and was surprised to see someone getting into electrical discharge machining. Those hair-fine wires, milled graphite electrodes, and ultrapure water baths can achieve incredible precision but are challenging even in an industrial context, though I know a few have made it work in their garage.
