Thanks to everyone on the list who responded with great ideas and
sources including the ebay seller KQ4BY.  I will probably go that route
since I intend to use the middle section of the coil for the link, so I
will need a fairly large coil.

If it does not need to be real small, one way to get a good coil 
is to wind one out of copper tubing.
Home depot sells various types, small/thin, bigger and thicker...
I made the pi net tank coil for the pair of 4D32 rf deck out of copper
I soldered big wire terminal lugs (the crimp on type) on the ends of the
coil and 
bolted it to large ceramic standoff insulators.

Here is a link to a picture:


My thanks to wa5bxo who still has my pictures up!
The wine bottle in the picture was used to wind the tubing on.
The home brew receivers are in the background...
