dunno if I'm wrong...but my knowledge about coils and magnetism says that a coil must be made always turning the wire to the same way...like a type writer machine does when it reachs the end of a page...
@ liadon666: what you mean is bifiliar winding: than the machine first spins clockwise, and after 1 layer of turns, it spins anti-clockwise.
Coils made that way are completely inductive, with a resulting magnetism of zero.
In this vid the machine is turning in the same direction all the time, so the resulting magnetism is just as great as when they made 3 long layers of turns at first.
I rewind transformers for a living polemount, padmount, single phase, three phase.... I always wind in one direction on all the coils I wind. Yes the magnetism IS just as great but it produces a more stable, consistant magnetic wave... Its kinda like saying(hypothetically) one layer produces enough magnetism to make 15 volts at 1 amp where two layers would make 15 volts at two amps (Not real figures just giving an easy example)
weeardguy: Bifilar winding means _two_ windings being wound at the same time, making a pair of near-perfectly matching windings on a single core.

btw..cool machine ;-)

These coils will all be separated when done. Customer wanted to wind a number of coils with one setup.
