Dear All,

We at GravityMagnet.com are more than happy to supply the best secondary
coils that can be made at reasonable prices. We have nice custom built
winding machines, and we have an absolutely fantastic method for finishing,
including polyprop, acrylic, q-dope, enamel, and other coatings.  On a large
coil it is our practice to put 80 or more layers onto a secondary coil. As
David said, this is a difficult, time consuming, and attention to detail
oriented business. The more coils we can manufacture, the cheaper we can
make them, especially to folks in the group.

Sincerely,

Miles Waldron
