Thanks for the info, espicialy about the baffles. I was reading 
somewhere on the net where a guy got his coil all put together, and 
the first time he fired it up, it arced inside the secondary and left 
a big nasty mark on the inside of the pipe, and he ended up scraping 
it and making another. So only ONE end inside, and use baffles!

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).
