It looks like a normally staggered single winding to me.  You will lose 
power because the coils don't line up.
One will always be slightly out of phase with the other IMHO.
If you join the separated ends, that will be part of a shorted turn.

Subject: [TCML] bifilary primary?

Hey there,

Has anyone played with a bifilar primary?  Specifically anyone who has 
worked with stuff
from DC Cox?
...
I am now in the process of rebuilding it again(It hasn't run since 2005) and 
finally I think I
figured out what the deal is with the primary supports... They are cut for a 
bifilar coil setup...
It looks like DC.Cox gave me something I didn't even ask for and I can't 
wait to experiment
to figure it out some but I do have a deadline and I gotta get this thing 
going again...

Has anyone else played with this?  I have put both spirals of tubing in 
place to fill the supports
up.  My original setup was about 3-3.25 turns of 1/2 copper tubing somewhat 
placed in these
supports but not perfectly laid out.  Now, there are 2 spirals and each is 3 
turns.
...
Best,
pete
