coil hunting
« on: April 16, 2005, 05:52:19 PM »
I been looking and hope someone knows of a better deal, so far I've found 60 KV
ignition coils at J C Whitney for 26.95. If you get 2 and hook the primary bassackwards
on one you get a neg. 60k for the skirt , and the other one can drive the cathode,
120kv, yay. Has anyone found or know of a better deal? Will 446 opposing miliamps,
223 on each coil be too much?If we go big is there a large inrush current to consider?
Does anyone have any info on Ken Rands construction techniques , I hear his plane was
very light and strong (home built aircraft way back in the past) I,m Just full of stupid
questions this morning isn't it great.

Most "pull it yourself' junk yards usually part with coils for about 4 bucks in my area. At this price, you could rip some open and have fun ruining....er...experimenting with them.

Yes I've looked at the junkyards but, stock coils only put out an average of about
32kv. Doubling that gets the voltage up some.There's a resister in the bottom of
a can coil, you can drive one with 15 volts without hurting it,reversing the voltage
on the primary doesn't seem to hurt them at all either. They need to run a while
reversed, I don't know if the core reverses polarity or what, I mark ones setup to
run backwards with a R with a paint stick.About 1 minute of operation and they
run fine after that, haven't hurt one of these coils yet,they're really well made
and can take a bit of a beating. Haven't tried pulses higher than 20,000 per min.,
they start to warm around there. Just touch the can if it's getting hot you have
to cut back the primary power some.

There are good chances of finding non-stock coils as well.  A lot of the 'heavy duty" coils from older pick-ups and such can have a bigger bite.

i picked me up two the other day.  Three bucks each, plus one dollar admission to get into the yard. Noow if I can just find my schematic. =)
