I’m pretty sure you can find videos on it on YouTube, but it essentially boils down to creating an array of copper wire in the shape of the rifling, inserting that into the barrel liner, then putting the whole thing into the bucket and hooking the wire up to electricity. This then slowly etches the rifling into the liner through electrolysis.
