First check Sue's zip-heatshrink, electrical wholesalers &
such carry it - Newey & Eyre, City Electrical Factors (CEF) etc.
Look in yellow pages, they are scattered in every town/city.


Is there some way to stop this braid siding off the joint. It sounds
as if it is in the right ball-park but I don't want it to slide of a
frequently flexed joint such as one I made on my mic cable.

Nylon overbraid is more for internal PC cables...
o The ends are uncut and will unwind/unbraid readily
o So the ends are covered in a short piece of adhesive heatshrink


Someone esle mentioned this too. Where on the net can I see
see and get it from?

Many places sell it - however if you just want a small piece &
I have the right size available, email, no charge. I need to know
the size it must fit over (eg, a plug) and the end shrunk size.


Once the heat-shrink has shrunk does it exert a force/tension
or does it shirnk to a new reduced dimension but without any
significant grip? IYSWIM.

It will grip quite strongly - but doesn't crush the cable.


Interesting to see you make a distinction. However I can not quite
see the difference between the two methods you decribe. Is "spiral-
bare-ends" where I bare the end of the wire, twist it so the strands
are spiralled together and then, um, how do I do "into one another"?

No...
o Cut the insulation off each end of wire - leaving bare strands
o Push the bare strands of wire-A into those of wire-B
o So each strand slides along the other wires strand
o Slight twist retains it long enough for it to be soldered
o Then slide heatshrink over it

Usual method is people twist wires in parallel together, solder,
then flatten it down to squeeze heatshrink over - not as good.

The zip-able adhesive lined heatshrink accommodates many
diameters - electrical places sell it for outside-sealing cables.
