Hi Greg/All

I've had a few ideas and have looked around the Web at commercial
coil-winding machines.  An old matrix printer (nice stepper motors)
should provide the bits for the prototype...  I'll set up a site at
http://coils.mss.cx for my design notes.

I don't think that putting inter-winding layers would be half such a
pain if the that was all that you had to do!  My idea is for the machine
to dash off a winding, you stick on the paper/mylar/whatever, then the
machine does another winding...  Spray-on HV varnish may be another
alternative.

As yet, I haven't built a coil, so the prototype will be set up with
this in mind.

Cheers
