Or-E-gummy. Wesstern Electric brand solid core NOS wire I have seen is paper bonded to single conductors chassis wire. Great design.Yeah, I've seen some stuff in the past that had what appeared to be a paper serve wrapping on it. It seemed to be more of a tissue type paper. I tried doing a serve with some of the kraft paper I have on hand but that wasn't happenin'. :)
I've got some white tissue paper here and I might cut some strips from it later and see if that goes any better. But the goal with the paper cables here was to try and reduce the involvement of the paper as much as possible. The paper acts not so much as insulation, but as a structural element keeping the wires spaced.
This morning I cobbled together something more suitable for an interconnect. The spacing is just 5/16". They're made in the same fashion, but I started with a 7/8" wide strip instead of the 1-1/4" strip I did the proof of concept with and I spaced the notches a bit closer together.
And here's the flip side, showing how the one flap overlaps the other:

Very cool, Steve. Did you use enameled solid-core (like 'magnet' wire)? The proper spacing of the conductors can be essential to helping control the field effect, as I'm sure you know.

Hi Alan, Does spacing between parallel wires affect how much low or high frequencies are there subjectively in an interconnect? If yes, what is the best spacing or spacing/wire diameter ratio?

Does spacing between parallel wires affect how much low or high frequencies are there subjectively in an interconnect? Subjectively? No absolute answers for that.
Objectively, the spacing will affect the cable's inductance and capacitance which will affect high frequency rolloff which will also be a function the source and load impedances of the two components you're interconnecting.
As a general rule, with line level components and their relatively high impedances compared to an amplifier and loudspeaker, capatitance will generally be the more dominant element as far as high frequency rolloff goes.
But lowering capacitance largely comes at the expense of increasing inductance, and if inductance is high enough, it too will begin to significantly affect the high frequency rolloff.
With a paired cable such as this, increasing the spacing increases inductance and lowers capacitance and decreasing the spacing does the opposite; inductance decreases and capacitance increases.
Also with a larger spacing, you have a larger loop area which means it will be more susceptible to external magnetic field interference. How significant that can be will depend on your particular environment.

The spacing affects not only interconnects, but speaker cable and power cabling as well. I wish I could help you more , but I'm not a cable maker. I do know that the amount of spacing is directly dependent on the wire gauge, as this deals with field effect, in addition to the actual electrical resonance of the particular wire used. If you want further erudition regarding this, I suggest you talk with Ron Paquette of Sahuaro Audio "cactusron@earthlink.net". He's been dealing with these design issues for many years.

Very cool, Steve. Did you use enameled solid-core (like 'magnet' wire)? No, the wire is bare. It looks rather like red magnet wire but that's because it was late at night and I just used my scanner so the colors came out kind of funky.
It's just kraft paper, GlueStic and copper wire. :)

Yup. The larger the loop area, the greater its radiated field and the more susceptible it is to external fields.
