maybe you`re right - i`ve only started reading archives, but imo it`s worth
working in this direction.

so we need to remove the strike rail and lift the coil upper from the
ground.

do you see a giant strike rail or stupid wide flat primary here? no? me too,
nevertheless in "most coils" they are still present. why not make primary
like here:

besides - your oltc2 ideally matches for this - only 1 turn, but instead of
this you`ve taken an "old 4.5" x 13" spark gap coil" - why?
:-PPP

i`ve read that we should use 2 hats - small & big, small one protects the
secondary, large - helps us to make big sparks :-)

first - if one specific person doesn`t have "120 foot sparks" that doesn`t
mean _anything_ - you know what i mean ;-)
second - i`am very very very sorry guys, coz this book costs only about $5
for russians:

as like this for example:

i`ve bought it just for fun, now it`s on my shelf, i`ve no time to read it,
but maybe some day - who knows?  :-)))
