[Milsurplus] Cable lacing

[antqradio@juno.com]

Teflon insulation cold flows under pressure, vacuum or not.
 
Worked on a MARS KWM-2 when I was in the USAF in the early 70's.  The
transceiver would work with the PM-2 power supply but not with the other
box (can't for the life of me remember it's designation).  Problem was
with the shielded pair of wires going from the on/off switch to the rear
connector.  Seems that the flat nylon lacing used cut through the Teflon
outer insulation compressing the shield to one of the wire pairs.  This
then promptly burnt open.  Very hard to find since the lacing was black
and so was the burnt area on the white Teflon cable!
 
So, which do you prefer, running stitch or individual tied off sections? 
Still tie the self locking "Collins Knot"?
 
Regards from a wet Arkansas,
Jim
