@ALL ,  Any suggestions on how to know if this is made right?

I could add a picture. I got 3 1/2  sets of wraps made when I ran out of copper. The dielectric cloth is silk. It is dry. I am not convinced that I should wet it. 

I charged the inside wires with some  static charge then using 'the little bit of foil' as a detector I detected no charge on any of thie device. [ the little bit of foil is a piece of al foil stuck to a straw and hung from a silk thread. It bounces back and forth from probe to probe of a cap charged with static e^-.]

For DMM readings :

if I put 2.5vdc battery terminals on the inside pair of wires I get 2.5 volts on the outer pair.

With the battery on as before, I shorted the outside wires and checked the area with a compas/galvanometer. I didn't see any deflection of the compas needle. I don't know where to attach the wires of the galvanometer, so it was really just a check with a compass. If there is any magnetism in the bifilar, it is too small to see a change.

what gauge wire?
  Touch your meter to one copper and one iron terminal .

The copper is 18 gauge and the iron is 19. its all there was.

I started out by touching the meter to one of each both ways then shorting the end of one pair and touching the meter to the free ends. nothing. But it is dry.

That is why I used the battery. I figured I'd see what this baby would do with some known voltage at the inside terminals.
The total length of wire was about 17 feet. It is what was left from the 25 ft after last night's first run.

Any more ideas?

I was just checking the wire for resistance. A long shot but... and one of the pieces of wire from the end of the battery holder broke. I will do the battery tests again.
Hang on

I did the battery test again. See above. just as the wires should be.

The other thing I just noticed is that with 2.5v on the inside wires, there is 15mvdc between the copper wire and the spike.

You need to wet this part if you want any voltage..
