Hi Tim,
Let me repost this since I screwed up an edit :-((.
You're going to get a wide spread of opinions on this and a lot depends on
how hard you push you secondary. I have two holes in my acrylic form
(8x36 winding). At the bottom, I did just what you are suggesting and
used a nylon screw to terminate the wiring. At the top, I ran the wire
into the center and up to a termination bolt on the end cap. I put an 1/2
inch acrylic bulkhead about four inches below the top turn to keep arcs
from going down the tube. I only used one bulkhead so as to not trap
outgassing. I also made sure the wire inside the form did not droop below
the top turn trying to keep the wire out of high field stress
areas. Lastly, I had a corona ring two inches above the top turn so the
internal routing should be surrounded by equal potential fields. Anyway,
I have achieved 74 inch power arc with no problems with the secondary yet.
