Hi,

The PIRANHA coil is finally going ;-))

For primary tuning, I set up the signal generator to frequency sweep 
from 100kHz to 110kHz.

This gave me a nice graph to show the primary frequency:

One "nice cable position" gave me 102.5kHz with is close enough  :-)

I then bolted it all together to finish it up (still need to poly 
coat the secondary coil):

Here it is doing 25 inch arcs at 1/2 power:

I can't run full power indoors.  I loose about 10% in spark length 
due to the hidden primary (lower coupling) but it wants to arc "too 
far" already  :-D

So it turned out real good!!

Cheers,
