[Elecraft] Toroid Winding

[Helmut Usbeck]

I have seen toroid winders for making power transformers and basically
it's a circular shuttle that that spins though the center of the toroid
while the toroid spins in sync with it.  It's a real mechanical marvel.

scroll down the page.  Always wanted to get one but have enough stuff in
the old Junque box/room, and as usual not enough bucks.
