Hi Tom & LF,
The slotted discs on the first web page are very similar to my first attempt
at basket weave coils for loading my trap dipole for receive when I first
became interested in LF. I made the basket weave forms out of CD,s. I still
have them in a box somewhere.

Subject: LF: LF/MF: Coil Forms
Hello group,
just to whom it may concern:
I happened to find a web site (sorry - only in German) offering coil
form kits made from polyamid 6.6 with 30% glassfibers for basket coils
and cylindrical air coils:
http://www.roehrentechnik.de/html/flachspulen.html
http://www.roehrentechnik.de/html/luftspulen.html
They offer accessories like plug in pins, sockets and simple litz wire
too, the prices seem to be quite reasonable (I don�t get any commission ;-))
For all of the coil forms you can find some graphs about L and Q versus
number of turns, kind of wire and frequency.
Up to now I have`n tested this source by myself, indeed.
