Do not wash it with water --- this is what you are trying to keep 
away from the coilform.  Use alcohol or acetone to strip it inside 
and outside prior to coating it with a good sealer.

Run bottom lead inside the coil and then out via a 1/4 inch x 2 inch 
long brass stud.  Have a nut in your base so it just screws into the 
base.  Easy setup and teaddown for transport.  Top lead stays outside 
the coil and slowly spirals up to attach to your toroid.

also good idea to put at least one 1/4 inch acrylic baffle in each 
end of the coil about 3-4 inches down.  Silicone in place with a lot 
of GE Silicone II (hardware store).
