The Gabriel Device, possible COP=8

Also, one of the key workings is the inner core of the secondary. When the primary flux level is able to penetrate the shield, that flux continues one to be attracted to the sec inner core, in which the flux induces current in the sec along the way.  Then the sec flux, because it is carrying current now, is suppose to be mostly if not all attracted to the inner core and not affecting the primary like a normal transformer does. Once the inner core contains a combination of flux from bot the pri and sec, it has to be able to contain all that flux to avoid saturation. So the sec loading also need to be of a particular value also, 'for a particular build', so as to not produce to much flux as to bring the inner core close to or beyond saturation. Your inner core looks of good size to work with decent power levels.    Let the core be with you.    The thickness of the shielding, and material used, determines how much input needed to break through the shield to get to the inner core, as the shield needs a certain amount of input for the primary flux to saturate it. And any power input beyond that point of saturation(rising ac sine voltage and current in the primary) the additional flux beyond that point then passes through to the inner core. So thin shield, less input to get correct phase shift, and thick shield, more input to get the same phase shift.

So first adjust your input for phase correction, then start adding load. Increase the load until there is a phase difference then back off on the load till phase is back to max shift and that will be the target input and output for your particular build.    

I have to look back and see, its been a while, but I believe you want your input limiter to be resistive(toaster). Not sure if a toaster has much inductance to affect the primary or circuit response overall much.  That is a resistive limiter if not using a controllable ac input.

I used a variac on input, cannot see any phase shift of significance from primary to secondary, adjust variac till I see 120vac on load.  Tried single 60w bulb as well and still got power factor very close to 1.
Could my shield be too thin for 60hz?  Shield is 3 plates thick of about 1mm thick steel insulated between plates to reduce eddy losses.

You call it shield, but isn't it more of a core? And for a core, yes, 3mm seems too little. I have experienced undesired effects in using thin elements for inductive flux guide. You may try to add some layers on top, tho, not funny to rewind that outside coil.


Can you try to run the prim. in series and /or parallel with a cap of high capacitance? would be interesting to see possible changes in the PF.

Mags;
So I read over your response and fired this thing up again with load attached but very small input current and like 5vac on the primary.  Adjusted variac on input till I saw the max phase shift(30deg).  Put 3.3ohm resistor on load due to low out volts and phase from primary voltage to secondary voltage increases to about 35deg however input current also rises.  Definitely no over unity on this the way it is right now but phase shift increase when lower resistance is added to secondary is interesting.  Will try and see if I can find a constant current on secondary sweet spot by trying varying load resistances.  Tesla mentioned two features in the patent, one being phase shift from primary to secondary and the other being constant secondary current when it's setup certain way. 
Dieter;
The outer shell is a core but from what I understand it is a shield to delay the flux from entering the secondary not high flux carrying like the inner core.  Problem I was seeing is that at high flux on primary the shield wasn't shielding hardly at all, need to lower primary flux to see shield effect apparently.

Lower resistance load on secondary gives more phase shift but lower total output power as the output volts drops with input at 6-7vac while input power and current goes up.  Without any load on secondary there is no phase shift to be found on this build so far.
