Thanks, that could come in useful.

it says , for wire breaks, just knot the ends together,

That is the standard way with all wire recordings. Most of the standard
systems run around 20 ips, so the duration of signal dropout due to the
amount of wire in the knot and the loss of head contact is not terribly
significant.

I have had to recover the sound from wire recordings of gaelic, which
become tangled and then the bits edited back in the wrong order (some
backwards). Now THAT was fun!

Low heat and stretching reduced 1mm outside diameter ptfe tubing down to
.5mm diameter.

That's gigantic compared with the wire diameter. You run the risk of it
hitching in adjacent turns and causing a snarl-up. Don't risk it, knots
are quite good enough.

..Hopefully superglue would have enough binding with the ptfe and
recording wire to make a joint.

I doubt if any glue would successfully bond to PTFE.

(If PTFE is non-stick, how do they get the PTFE coating to stick to
saucepans?)
