Hi Jeremy, Coilers,

Leave about a two inch space between the ends of the strike ring and you
should be fine on the "shorted turn" issue.  As to its spacing from the
primary, I've found that if it's a couple of inches above the outer-most
turn of the primary, it works just fine.  My primary is 10 turns total,
with the tap at turn 7, so there's a bit of auto-transformer action in
my primary making the free end hot.  I don't have troubles with arcing
from the primary free end to the strike ring.
