Re: first coil help



Original poster: "James Mathisrud by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jrmathis-at-pressenter-dot-com>

    update: well, i moved my primary up so that the first turn of the
primary is even with the first turn
of the secondary, i noticed that before the 3rd turn of primary was even
with the first turn of sec. this
helped a little. now im drawing off 4-4.5 in sparks, as opposed to 2in
sparks, but still no breakout!
tomorrow, i will start building an mmc cap (research and such) in hopes of
my crap caps being the main
problem. unless i can find someone who can measure the capacitance.
allowing me to adjust where necessary.
thanks to everyone
Ryan
