Re: [TCML] DIY Tank Capacitor - Plate configuration confusion

["Brian Foley" <ka1bbg@xxxxxxxxxxx>]

Hi, the best are thin and wide, smaller mesh......should weld the two rims
in a few places, i have them taped with vinyl tape, so i can get breakout
off the topside...the tape burns thru often.....after welding some smoothing
with sandpaper would help prevent breakout from the rim, also once welded
the clamps that hold the 2 pieces together could be removed.....
it works just dandy for the price.....look at some of the bigger coils,
toroids made from chicken wire and foam rings.....they sure toss out the
sparks, no problem.......another one i have used, 2 identical alum frying
pans, sand the edge flat on both pieces, epoxy together, then sand it a
bit.....to make the joint smooth.....works just dandy especially if they
were tossed at the dump. you have to degrease the metal or the epoxy will
not stick....i put a hole and mounted it on the lathe, run some sand paper
over it to get a nice finnish......cul brian f.

Love the fan shroud toroid. Very creative.
Toroids are a rare bird to find in nature.
Does it break out at a pretty low voltage, or will it contain it well?

HI, Grant, first there are no idiots on this list.....some have much
less
knowlege of coils, some have extensive physics, electrical, engineering
backgrounds, math background who often give regularly of the
knowledge....write programs, and might even be a ham radio operator as i
am.....so skip the idiots...Jeff Behary who runs
www.eletrotherapymuseum.com/
has a huge stack of older information, and i bet he would be able to
point
you to some information, despite how busy he is..
for stacked capacitors.......cul brian f.
