Here's the coil winder. The counter and motor are at www.surpluscenter.com: counter motor. I positioned the counter on the side right behind the shuttle and guides, so it's directly in my line of sight as I'm winding.

I used lengths of brass rod to form guides.

Two strips of plastic separated by springs form the width guides. A cam on the motor shaft bears against a micro switch to increment the counter once each revolution.

Tension is provided by blocks of wood and aluminum lined with felt, bolted to the side with an adjustable bolt.

The shuttle is an aluminum cylinder threaded onto a length of threaded rod, with a groove cut around it to guide the wire.

The electronic parts are all available from Radio Shack.

Here's the ciruit:
