anybody have any airdux (or similar) coil stock they wish to part with
(cheap)?


Have you ever thought about winding your own? Find something of the
right diameter - PVC pipe, wood dowel, cardboard roll, etc. Wrap it
with waxed paper, then wind the wire on it tightly holding the ends down
with tape. Mix up some epoxy (24-hour cure will be stronger and more
flexible, but 5-minute epoxy will also work). Apply the mixed epoxy to
your coil in lines about 1/4 inch wide. Use at least six lines to make
a sturdy coil. Let the epoxy cure for several hours to overnight
depending on the epoxy chosen. Carefully withdraw the form and unroll
the waxed paper from the inside of the coil. It's really simple to do
and you have a real homebrew rig.

Thats my plan. I cannot afford the real air/mini-dux.

Forget the epoxy and use Duco Cement.

"polyester resin instead of the epoxy as it will not cure properly. I
won't say why, but instead leave this as a mystery for the readers of
this newsgroup."

For me the Duco Cement has always held better than epoxy.
