[TCML] Inductor Construction

[Quarkster]

Dave -

Tyler is not trying to create a parallel multifilar winding, he is just 
trying to quickly and easily connect all the physically-parallel conductors 
in the cable into electrically series-connected conductors. Since all the 
conductors "start" at one end of the cable, and all "end" at the opposite 
end of the cable, I don't see how one can "easily" connect the end of W1 to 
the start of W2.

A sketch showing exactly how you could the connect the end of W1 to the 
beginning of W2, etc without completely disassembling the cable into 
individual conductor segments might help me to visualize your concept.

Regards,
Herr Zapp
