That last one is just a standard lathe - i assume he just winds it in by hand and uses judgement to stop the chuck at the right time. makes me wonder what you could do with a hi speed power drill and a bottle jack!!!!!! Much skill needed i suspect

powerdrill.. would transfer too much energy back into your hands if hand-held. the friction is massive. imagine producing that much energy by hand.

Tesla battery connections are friction welded. Ultrasonically. It must be a very fast process as you can't get lithium cells too hot. For prospective, Spot welding is the norm, as soldering is too slow.

For prospective, Spot welding is the norm, as soldering is too slow. That same process has been used for many years on a microscopic scale to weld fine wires between silicon chips and their external contact pins when maufacturing ICs.
