primary conductor size and spacing



Original poster: "Bill Vanyo by way of Terry Fritz <twftesla-at-qwest-dot-net>" <vanyo-at-echoes-dot-net>

For my first coils primary, I used 1/4" copper tubing and 1/4" spacing
between the turns (1/2" between turn centers).  That was with three
15/60 NST's.  For my next (second) coil, I'm adding a fourth 15/60, and
would like to someday replace the NST's with a pole pig.  For this next
coil then, should I use 3/8" tubing and/or 3/8" spacing between turns?
