Dear Thane,

  Could you post complete electrical circuit drawing?
 
  Also do you convert HC coil output to DC?

  Nuri

IT IS NOT COMPLICATED,

1)
HV COIL CONNECTED TO TOGGLE SWITCH AND SHORTED.

2)
HC COIL CONNECTED TO 10 OHM LOAD AND SWITCH IN SERIES.

THAT''S IT.

NO AC TO DC CONVERTING.

Thane next time take pictures as you go building the coils. My brain got all twisted reading the textual instructions alone.

I DID POST PICTURES SOME TIME AGO.

ALSO I FORGOT TO MENTION I MODIFIED (CUT UP) THE "E" CORE SO THAT I COULD MANUALLY LINE UP ALL THE FINGERS WITH THE MAGNETS ON THE ROTOR.

IDEALLY THE BEST METHOD WOULD BE TO MAKE A BOBBIN LIKE I_RON DID AND SIMPLY SLIDE IT ON THE MIDDLE FINGER OF THE "E" CORE AND LEAVE THE "E" INTACT (LESS AIR GAPS = BETTER PERFORMANCE) - THAT IS THE NEXT STEP NOW THAT I HAVE THE KINKS WORKED OUT.

Thanks Thane.
Can you give us an idea of the gauge of wire and number of turns used for the HV coil.
Thanks.

I ONLY USE 30 GAUGE WIRE FOR THE HV COILS. THERE ARE BETWEEN 1200 - 1500 TURNS I THINK (I ONLY COUNTED THEM ONCE). I USE COIL RESISTANCE AS A GUIDE AND USE BETWEEN 80 - 150 OHMS DEPENDING ON THE CORE DIAMETER AND LENGTH. CORE SIZE IS 1" SQUARE X 3" OR SO.

A TIGHTER MACHINE WOUND COIL MAY REQUIRE LESS TURNS BECAUSE IT IS COIL IMPEDANCE THAT MAKES THE HC COIL DO WHAT IT DOES SO THE INDIVIDUAL WIRES NEED TO BE CLOSE TOGETHER.

Typo, typo, didn't you mean HV coil? Can't you get anything right?  YEESH

Hehehe, Mr T, thank you so much for the excellent description. I know you have said a lot of this
before but repetition certainly helps... as you can see by the response, it brought a ray of light to
many of us. OK, got it, I am held up with "other" things at the moment but want to build a new
rotor...and good mot core are getting hard to come by.

Now one point I want to make is I am quite sure  you rotor construction is playing a contributing
factor to the working of your machine... prove me wrong!

YES THANK YOU HV COIL.

CAN YOU BE MORE SPECIFIC?

BUT, I THINK YOU ARE WRONG BECAUSE WE GET BETTER ACCELERATION FROM A LIGHTER PLEXIGLASS ROTOR BUT FROM A SAFETY STANDPOINT - I DON'T LIKE THE EXPLODING PLEXI ROTOR EFFECTS.
