    Could I have a few suggestions on what type of commercial adhesive
    would work best to permanently glue two lengths of insulated figure 8
    wire on top of each other?

    The bond must be continuous and flexible over 30 metres, so that rules
    out hot melt, ties, heat shrink, etc.

    Ideally, something that holds when pressed and then dries. Maybe a
    clear contact type, or something like PVC pipe cement that melts the
    plastic together.

    Does anyone have any experience with this type of thing.

    I'm going to suggest Plummers Goop, or like Shoe Glue. The glue
    can be thinned to spread easy. Should hold together relatively fast
    but will take a day to cure. I use lacquer to thin the stuff.

  3. Is "figure 8 wire" a thing itself, or something you are doing to other
    wire?

    I take it as simple stranded wire. Take two wires and twist them together.

    Assuming you want the conductors like this:


    (O)(O)
    (O)(O)

    I'd use contact cement.

    Paint it on both jackets where you want them to bond, let it dry per
    the directions on the package, and then press the cables together.

    One could also do it flatwise:

    (O)(O)X(O)(O) where at X, I'd use RTV silicone.

    Personally, I'd use RTV in the one-on-top-of-the-other arrangement, but
    that's more a matter of taste. One caveat with RTV is it takes a couple of
    hours to set up, and 24 to cure - contact cement is right now. :)

    Cheers!

    Is there a particular reason you can't use proper 4-core cable? If
    it's for speaker use, you can get 4-core flex for use with Speakon NL4
    connectors for biwiring.
     
  9. There are solvents for PVC. Try a few glues and see if they work.

    try shoo-goo (sole repair compound).

    you may have to tie cables the wires while it cures

    another possibility is cyanoacrylate

    I guess ideally it should be fusion welded

    stacking zip-cord like this: 88 will make it much less flexible
    (by experiments bending zip-cord sideways I estimate 20 times stiffer)
    regardless of what adhesive you use.

    If you're wanting a 4 way flat zip cord: like this: oooo you can probably
    buy that somewhere.

    Bye.

    RTV taste very bad.


    Use the electronic grade stuff. The RTV that smells like vineger rots
    the wires. Also no matter what glue you want to use, clean the wire's
    jacket before you try to glue it. They often have oily stuff on them.

    Keeping RTV at 50C overnight is enough to finish it off unless the
    layer is much too thick.

    Back in the early 60's pvc cabling in LM Ericssons ARF crossbar
    exhanges was glued into blocks (rather than using conventional waxed
    twine lacing). They supplied a clear pvc glue which was thinned using
    laquer thinners and it set reasonably quickly. Such techniques and
    products were discontinued because they involved hazardhous
    substances. I would suggest that clear pvc pipe cement as used by
    plumbers is the closest thing there is today. Silicone sealants and
    similar products take too long to cure without using cable ties to
    hold things together while it cures.

    Some people have smaller heat boxes than others. :>

    I had assumed, perhaps incorrectly that it didn't have to remain
    straight when it was put into the heat box. It does have to be held
    together while the glue dries somehow.
