I bought this Tesla coil years ago...
fixed spark gap, Allanson 12kV 60ma $300 - shipping $75
a three (3') foot stainless gazing ball for a maybe one day Van de Graaf generator. (bought new)
$200 - $50 shipping
four (4) Aerovox Energy Discharge Capacitors $300/1 $575/2 $825/3 $1000/all
These were shipped to me truck freight so I'd say that you probably need to be able to pick them up.
19X uF
10kV DC
100 nH (max)
9800 Joules
These were for a quarter shrinker that I never did complete... bought second hand.
Thanks for looking!
Please ask with questions/offers!

Hey dudes,
I recently got turned onto amateur electronics and more specifically tesla
coils. The main reason for this is for end game, powering a lifter, using
the Befield-Brown effect, and from what i understand, these things can
supply the types of power levels im looking for. Everything is going well
so far, just picked up a NST , 15kv 30ma, and started the build. Its a
small one, made some salt water caps, wired everything up according to the
plans found online, (pretty simple), but am running into some issues.
Specifically, its not working LOL (spark gap isnt triggering at all). Ive
heard the with these types of DYI caps, a large amount might be required
for the type of NST im using, 30ma. Basically im lookin for some advice on
different things to try, ive read about the miniature cap cell/grid and
those look interesting. But im new to this stuff and not prepared ot jump
in that deep yet. Any advice to a new coiler, wheher it be books, website,
personal info, or anything would be greatly appreciated. I can tell im
going to get pretty deep into this stuff. Anyways thanks,
Dylan S.

Hi Dylan, what is the width of the gap in your spark gap? You should be
able to get at least a spark across the gap if the gap electrodes are
close enough (ie, a little closer than is required for them to spark
when you just place the spark gap in parallel with the NST).
It might help to know what plans you are working from, and to double and
triple check all of the connections. Do you have any way to measure the
capacitance of your capacitors? If not, there are some websites that
can give you a rough approximation if you are using, say, glass bottles
with known dimensions (glass thickness, area of glass covered by salt
water). This is one site with such a calculator, although I haven't
used this one in ages: http://pokusy.chytrak.cz/programy/calculat.html )
One thing to watch out for is to make sure that your capacitor value is
not of a value which will be in resonance with your NST; this can lead
to a situation known as "resonant rise", where the voltage will rise
higher than that generated by the NST, and can possibly lead to a
failure of your NST. Recommended values, depending upon spark gap type
and NST used, can be seen here: host.teslamad.com/mmc.pdf (from that
page, a capacitance of 0.008uF is recommended).
For general theory, you can't beat Richie Burnett's page at:
http://www.richieburnett.co.uk/tesla.shtml , and if you are looking for
a good simulator, you will fine none better than Bart's JAVA TC at:
http://www.classictesla.com/java/javatc.html

Wellllll.
It ended up, as i understand it, with GE owning Edison,
rather than vice versa. GE found it useful to promote
'Edison the Founder' as PR ploy. Hint: look at who
hired C P Steinmetz and for what... Independently,
turns out Henry Ford was a huge Edison fan, with money
and energy to spin history.
The history is complex, fascinating and away from
'Practical Coiling'.

Hello Dylan,
I've done a lot of work recently with Biefeld-Brown devices, if you want to
contact me off list. The short answer is, there are better/easier ways to
power a lifter or other B-B device than using a Tesla coil.

I had to hold the joints together with a piece of copper wire and a sheet metal screw on each side of the joint. The toroid works well and is not too heavy (~25 lbs).
