It is caused by resonant rise in the absence of a load. If you want to see the schematic below in motion, take a look at this circuit simulation animation in Java.

While I'm at it, rotate your core 90º so the split is vertical and not under the windings.  Do not change the position of your primary windings - only change the position of your core. This will facilitate the alternating attraction and repulsion of core halves when we later make the currents in these two windings, out of phase. 
It doesn't take much imagination to realize that such field arrangement will cause the halves to vibrate strongly as they slam into each other, on each attraction cycle (most strongly at their mechanical resonance frequency).

I'll reply to your electronic question shortly.  Most likely, it is caused by resonant rise.  I need to check how long BOTH transistors stay open with those component values.

Dear Verpies.

Thanks again. It is very late here!! I will alter the rotation tomorrow and let you know the results. 

Cheers Grum.

Dear Verpies...
Could you please explain why I am seeing such an excess of voltage than what I would normally expect.

Thank you in anticipation.

Cheers Grum.

I do not know... what i know is that every Royer oscillator i made, and i made quite a few, mostly with MOSFETS but some with plain bipolar transistors, the resonant rise of the LC (primary, center tapped topology) was restricted to double voltage p-p per winding leg or x4 p-p voltage for the whole coil (both legs) in reference of supply voltage (DC, battery value). I noticed no more voltage can be resonant risen since the source -batteries- would not supply any current due to "balance" of incoming voltage to coil's voltage.

Verpies.. what do you mean by resonant rise in a royer oscillator the coils can develop... as much voltage as they like?

ps: I see the o-scope shot is not a clean sine wave rather a distorted one. This means heavy saturation in my view. With those component values i would expect an audio frequency rather than 93 or so KHz. That means you drive the core to heavy saturation having the inductance almost nullified.

That's true when the circuit is loaded.

In an ideal circuit -  yes.  In practical circuits, any resistance in the primary or a load across secondary will limit those values.

Take a look at the fragment of the Royer's circuit below with the irrelevant parts grayed out (as if the SPDT switch S1 was in the middle position).  Note that only two inductors and a capacitors remain in the circuit and together they form an LC tank.  This LC circuit can oscillate at any amplitude that S1 pumps it up to.  There is no limit to it in an ideal circuit.

ps: I see the o-scope shot is not a clean sine wave rather a distorted one. This means heavy saturation in my view. With those component values i would expect an audio frequency rather than 93 or so KHz.

That's because the switching frequency of S1 is not precisely matched to the self oscillation frequency of the two inductors and the capacitors, that are not grayed out.  If I controlled S1 through a real feedback like in a full Royer, then it would be matched.  The values are scaled x1000 for the ease of the simulation, so don't be preoccupied with them and the absolute frequency. The ferromagnetic mutual inductance and saturation is not simulated either, to simplify the sim.

@a.king21, I agree with your ideas just need to experiment this weekend. playing with coils gets no where without a few different and unusual ways to put the whole lot together. Looking back at the bedroom vid and green box vid it is obvious as you previously stated there is no Tesla transformer as such, so other avenues must be tried.It still might be Tesla just a different patent or idea of his put together by Kapanadze to get desired result.
