I'm lucky on that one! My wife bought me an 8 inch EMCO with back 
gears and speed control on the head and a magnetic break. That baby 
will stop on a dime from 3000 RPM! When I wind coils I set the back 
gears to give me the thread pitch I want then I start up the head 
slowly and watch as it goes.

How do you space your windings on a jig like that? I mean it has no
longitudinal feed so your going to be holding the wire in your hand.
Not very precise if you ask me. Unless you set it up like a giant
bait casting fishing reel.
