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.
