Thanks for sharing this Marc.  I've been wondering how the other flat
coilers have been making out.

I finished the windings on my 25.25", 12 gage, close wound flat spiral coil
today.  It turned out very nice.  It will be another week before all the
polyurethane, resin, and Plexiglas are in place.  On this coil I'm going to
have 2 and possibly more sheets of 1/4" Plexiglas between the primary and
secondary to eliminate the spark-through.  I made the outer lead of the
secondary coil feed through the plywood base.  I'm hoping this will reduce
opportunities for sparking though (is this what you mean by racing?).

Do you have any pictures?

Dave

Well,
 To give an update of my 20" flat coil to date:
I wound a somewhat conical primary that hangs under the secondary, 70
deg. angled inward, 11 turns at 20" in.
  Racing arcs along the sec. windings are a real problem. I tried ground
out and ground in. It just seems that no mater what, they race? The arcs
show some good potential, I just need to get them to a topload?
 Longitudinal, shortatudinal or frustratingatudinal, this is a
challenging coil! Space wound with heavy wire would help in this, but
then we wouldn't learn?
  I'll keep playing and report as i go,
Marc M.
