Hubbard coil

[PhiChaser]

I have (nearly) finished building my own version of a Hubbard 'transformer'. The center coil isn't full of a good magnetic material yet but I'm 90% there anyways... Everything fits nicely but I may end up getting a stainless hose clamp to pull everything together even tighter (Hendershots capacitors had to be 'tightened' to get the right farad capacity so ).
I don't have any real measuring or testing devices other than a cheap Greenlee VOM but that will change eventually.

Specs concerning my build:

All conductors are 18awg bifiliar speaker wire wound single layer. All coils have 36 wraps.
The outer eight coils (coilset) are 6" long 5/8" diameter 1018CR steel rods. Total coilset length 621" +/- 1" (core length)

At the end of each coil as the wire transitions to the next core the wire is twisted once to keep the current direction the same where the coils are touching when placed side by side.

If you can imagine a four foot (4') piece of steel rod single layer wound with 18 awg bifiliar speaker wire from one end to the other, then cut the rod (not the wire!) into six inch (6") sections and 'fold' them (twisting the wire where the rods 'fold') to form a circle. Now tie the ends together in a mobius fashion (maintaining current direction) you have what I've constructed here.
Eight 1:1 (primary) transformer/coils close (flux) coupled in a cylindrical formation and surrounding a (secondary) induction coil. Does this qualify as a semi-toroid?

The center coil (tapcoil) is wound around a 3/4" piece of pipe and the conductor length is pretty close to 124.2" (1/5 coilset conductor length).
The two bifiliar wires are tied together at one end of the tapcoil so that the current will run in both directions (down into and back out of the coilset).

Theory: Primary 'coilset' will act similar to (Leedskalnin's) PMH holding current to be inducted by secondary 'tapcoil'.

The challenge: Keeping the current flowing forever around the coilset.

Suggestions/comments would be appreciated.

I know that this thing is supposed to be some sort of transformer...

I have put 5v@500mA (via phone charger) through each of the coils as well as tying them together for the 'longest trip' and arrived at the following voltage readings at the input points:

Primary Coilset      :0.68v
Secondary Tapcoil   :0.16v
Pri. through Sec.   :0.85-0.87v

Nothing terribly exciting so far. As expected there were zero readings on the tapcoil when I put this little bit of juice throught the coilset. Still need to find a variac heh heh...

Wire on metal rods. Fun!

Removed all the electrical tape from the ends of the primary coilset today and taped on plastic covers so the wire twists between cores can be seen (and won't fall off!). This is the bottom; The top has a hole for the tapcoil and I sleeved the wires where they left the plastic 'case' so they wouldn't chafe.

The cores are important so that the magnetism is quickly shedded when
the power comes off.

Can you get your hands on soft iron welding rods? Iron (as opposed to steel)
is sometimes used for rods in building foundations because it doesn't rust
as much).

The idea is that the current STAYS in the primary conductors and doesn't come out. It gets inducted into the tapcoil as a +/- DC (AC!) pulses. At least that is the idea: those steel rods stay electromagnets constantly. (Maybe a good DC blast to get it going?) Power goes in, finds oscillation in the conductors, and keeps going round and round in the SAME DIRECTION over and over and over (like the coils in the PMH!). The tapcoil (secondary) is supposed to have a higher magnetic value than the outer coilset (primaries) which stay 'loaded'. It is my hypothesis that this stronger magnetic field in the middle of these coils is what will allow this to happen.
The output coil will definitely have to be able to pulse and 'unload' the inducted charge, that is for certain. I have some small welding rods but they aren't soft, they are very hard. Maybe ferrite (antenna) rods? I'm not sure if there is supposed to be an outer winding that surrounds the entire set of coils? I haven't done the math but I'm certain I don't have enough wire for that at the moment...
I can see other ways of winding these rods but this particular coilset is done (as far as the winding goes anyways heh heh). 
Thanks for the link Paul!

P.S. I did get a small hobby vise but I haven't used it yet...
(EDIT: After looking at a TPU pic I think that there should be an outer winding that connects (mobius style) to the 'tapcoil' which I think should be an inner AND an outer coil both... Hmmm, makes more sense now.)
