Something to do with the compression on a twisted-pair cable
caused by
over-tight nylon cable ties screwing with their twist rates, and thus
changing their Crosttalk characteristics...
Yep.
For starters, the stuff that Dan Mahoney is looking for is properly
known as
waxed linen lacing cord. In a past life I used to order the stuff
made
by Ludlow Textiles through Graybar, their part # back then was
89039323. It's
not always in stock in individual stores.

Lacing is a lot slower than using platic ties, and doing it is
rough on your
fingers. If you're lucky you know a data tech who can show you how
to do it
properly, it's really not something that you can just describe in
writing.
The UK avionics industry used to (and may still) use thin PVC tube
for lacing
- kind of like thin insulated wire without the wire. It's got several
advantages:-
1) Much kinder on the fingers
2) It stretches, which:-
a) minimises the risk of overtightening it
b) the elasticity keeps it snug, it doesn't work loose over time
as easily
3) it doesn't rot
And yes, I am old enough to know how to do it. But I disagree with
Randy (what's new)
I'm more of a Techosaur than a Telephant.
