A very interesting idea. If I understand you correctly, it would look like
this:

p=s: upper part of primary being "misused" as secondary.
T: Tertiary coil (was secondary)

In comparsion here is a "conventional" maggy.

If I understood your setup correctly, it would have to be run without
a ground. While I can understand that schematic #1 WILL produce
spark output, what spark lengths can one expect? By pure gut feel
(as I have never tried this), I would think a simple 2 coil setup should
produce longer sparks and that the "traditional" maggy setup would
also produce longer sparks. Your suggested idea seems like a huge
autotransformer ("secondary" part of the primary and the secondary
coil now being used as a tertiary coil) being fed by a resonant power
source (primary coil and primary cap). I would expect the output of
this setup to be MUCH more dangerous than a traditional coil or maggy
setup, because the 50/60Hz are superimposed on top of the high
voltage output (not that I recommend taking hits from a traditional
coil setup). Could you explain your suggested setup a bit further
(i.e: why does it work and if it produces longer sparks than a
traditional coil, why)? Of course I mean spark length comparison
for equal input tank circuit (i.e. input VA and input Joules)
How do you go about designing such a system (i.e. formulas)
For a traditional maggy you would need these parameters:
Total C = (Cs+Ctoroid)(sec)+(Ct+Ctoroid)(tertiary)
Total L= Lsec+Ltertiary
FRes for the "output" side would be the function of Total C & L,
so I would need to tune the primary to this "combined" frequency.
How would I do this for your suggested setup? I.e.: how do I
calculate the capacitance of the "secondary" part of the primary?
Thanks.
