Re: PIRANHA - New Top Load Configuration

Terry,

Very nice coil project.  Excellent work and nice craftmanship.
I have a question about the new topload. Do the discharges rotate around from sphere to sphere or do they seem to leave from only one? Just curious.

Hi All,

My PIRANHA SISG coil with the sphere top terminal is getting about
done.  I just need to work some on the wiring and tuning still.

The whole coil is looking like this:

Pretty close to the concept :-)

The secondary will eventually be coated with Envirotex. and the top
of the base will have a thin cosmetic cover so the primary and guts are hidden.

The top terminal seems to work very well!

The last picture there is the corona off the top of the secondary
under the terminal at 300kV peak.  It will not breakout even at that
voltage ;-) Things might need a little adjustment there but nothing bad.

The dragons are cute and the primary deck worked out well:

The primary coil is actually under the sheet of acrylic and held by
four brackets glued on with 'Weld-On' acrylic cement.  The coil is
just insulated #4 wire:

The turn to turn voltage is not super high so the coil will be just
wound tight in the brackets.

I just transferred the SISG guts to a new base board the fits the new case:

So it really is coming together now ;-))
