I have my own machine shop and my own metal spinning equipment and I've
done both and in my opinion it is far easier to spin a toroid than to
machine a rotory spark gap out of solid bar stock! As for minning and
refining ones own base metals, well to do the mining your going to have to
pay someone to let you work their mines or go find your own and the
refining is going to be either very costly or very work intensive. There
are some abandoned copper mines not too far from where I live and as a kid
I picked up several hundred pounds of copper ore and It would be easy to
purify the ore ( its mostly solid copper with a little rock) but I have
tried to draw my own wire and believe me you would much prefer to purchase
it that draw it, let alone insulating it.
