Hello everyone,
I'm kinda stuck on why my coil wont work, obviously. First off,
the problem more specifically is when I power it up, the gap fires once
or twice and then all I hear is the hum of the transformers. When its
dark I can see a 1 inch arc from the toroid to a grounded wire, but
that's only once or twice (along with the gap). I believe it might be due
to mounting almost everything on wood. I always had that thought in the
back of my mind but never really wanted to listen. I'll list my specs
down below.
Secondary:
4.5" by 25" with 26awg
TeslaMap says 1,403 turns
6" by 22" aluminum duct toroid
first sec winding is 2.5" above first primary winding
Primary:
.25" copper tubing spaced .25" apart
about 9 turns tapped between 8-9
20 degree inverse cone
inside hole is about 5" raised about 1.5" off the mount board
Power supply/etc.
4 stack MOT (ballast is sec. shorted MOT) run at 120v unknown amps
50nf cap (5 bucket caps)
now using single static gap (used to use multi gap mounted on wood
which performed less results)
If inductance calculations are needed or anything teslamap would have just
ask. Same with other information. If remounting is the problem, I may have
a cheep source of acrylic. Any suggestions or comments will be greatly
appreciated. This is my second coil, my first was a 3.5"inch (but it
actually worked). Thanks for your time, I look forward to any responses.
