  Jerry,

  I have built coil forms using the design of Chris Chapman. I use .062" =
circuit board material without the copper layer. I cut out the shapes =
with a saw and use a Dremel tool to cut slots as needed and use epoxy to =
bond it all together.=20

  In years past, I had difficulties in finding a "manual" coil winder =
and ended up with an old fashioned had drill.  (As you know, you have to =
search using the correct words or your mouth pursed just right to be =
successful.)

  =20

  Anyway, that hand drill is what I ended up with.  The EBay choices =
shown by Barry are interesting.  Thanks, Barry.

  =20

  Never-the-less, in past, I had more trouble finding proper shaped =
ready-made spools or bobbins to wind a coil.  And, if I tried to =
construct a rectangular shaped form, I had trouble getting the =
sandwiched parts to stick together!  I suppose that I did not have the =
correct adhesive.  I tried several without satisfaction.

  =20

  If anyone knows the secret to building a rectangular form, materials & =
glue, I'd appreciate knowing it.

  Regards,

  Jerry
