So what if you cobbled up a 2N-whatever pass device in the line?

That produces a spark at the point of contact and I've gotten some real good welds that way.  Letting the wire touch the bolt/resonator and using a switch or similar just produces a spark at the point of contact with the capacitor/switch and nothing much happens where I want the weld.  Now the big problem is holding the end of the wire with something, so I can turn loose of the wire easily after welding.  Things are so small it's really hard to manage.  Hmmm, maybe hemostats, but I don't want to bend up the wire. After it's welded, I don't want to mess with the wire.  I've noticed after one weld, the wire is pretty much shot.  Not sure what this nickel wire will do, but I figure I've probably only got one chance.
