Re: [TCML] New Coil

[John Forcina <forcijo10@xxxxxxxxx>]

If i read correctly in this photo,
http://www.cmnow.com/TeslaMan/Toroid/tn1.htm You plan to have your primary
coil 4" That is going to be way too low and your coupling between your
primary and secondary coils will be very small allowing very little energy
transfer into the secondary coil.  I recommend you plug your coil specs into
Javatc http://www.classictesla.com/java/javatc.html .  Adjust your primary
height and diameter and adjust your primary coupling to about K=.14
