1" Baby coil, first light

["Tesla list" <tesla@xxxxxxxxxx>]

Original poster: "James Howells" <james@xxxxxxxxxxxxxxxxxxxxxxx>

After 5 months and lots of help from all coiling groups I THINK I 
have a working coil

I invite your decision as to whether it is a working TESLA coil or 
just a look alike acting as a induction transformer

I would also like your comments as to the reason why three different 
primary coils work almost as well on the coil



The total details are lengthy but, the main components are:
   * 1 inch  dia secondary, wound over 3" with  .004 inch ( 4 mil 
USA - 4 thou UK .. .1 mm Euros)
   * Ignition coil driven with rectified out put  ( two power diodes 
on the output leads
   *  10 X 10 nF in a string ( ser) 2 strings in parallel = 2 nF
   * Static, but adjustable  spark gap - with silver button electrodes
   * 1St  primary raised spiral wound bare wire 0.052 inch dia . Six 
turns .. inner 2 inches outer lap 3.5 inches approx .3 inch spacing 
total height 2.5 inches
   * 2nd primary coil  raised spiral  from automotive, copper, brake 
tube .192 inch dia  4 turns  at 1/2 inch spacing, 1.35" height, 3 " 
ID and 7" last lap dia
   * 3rd primary flat spiral of 4 turns MOT filament heater wire. 
Close wound  with insulation on .wire 0.05 "dia, insulation .039 
thick- which will be the spacing also
   * Top load 1.38 " dia foam  rubber  ( sold as a cat's Toy) 
covered in self adhesive Al. Tape
All these primary coils work well with the same Cap and secondary  . why ?

THANKS TO EVERYONE FOR THEIR PAST HELP AND ADVICE - all around the world !

IF this is a real Tesla . I promise to give up the ignition coils and 
go on to my NST

PS. I also got this working with HAWG salt water caps  made from 
small Heinz pickled beetroot jar -  for the salt water enthusiasts
