But then you have to go all out and use cloth insulated wire. Our Towe's Ford museum used to do the occasional production run.
The only thing with those replacements is that tie wraps crumble over time while waxed thread usually doesn't. That alone can prevent a major "oh s..t" situation in an aircraft.

Out here the clear ones last about one year in the sun, the black ones about three years. I used them on irrigation cables but now went to wire ties. Those never break.
Where I found broken plastic cable ties was in lab equipment of the five-digit Dollar class. Replaced it with wax rope, never had issues anymore. But then the old spool of wax rope ran out :-(
Still got a spool of very flexible cloth-insulated litz wire from my grandpa.

If it's really waxed polyester twine you're looking for, then try a yacht chandlers. It's used for whipping the ends of ropes.

What ever happened to Gudbrod (sorry, can't type the diacritical marks)?

Marine supplies are far away from here, we are in the foothills. But Jim Stewart suggested Koroseal which is used in aircraft. And we've got a runway almost right next to the house ;-)

I think a more common description is lacing cord. Digikey produces one hit, but it is for a not stocked 50 pound spool by Alpha Wire.
It probably is more than you need but I use a DS1315 in wide SO16 which keeps my RAM non-volatile as well. Works well and needs no dedicated control lines - it is controlled by sniffing for code sequences when writing to RAM.
I've not experienced any of the Dallas availability concerns you expressed to Vladimir.
Mouser and Newark list several types of lacing cord. Just search for "lacing" to get the hits

The only thing the Mac does is work and look beautiful. It's an awesome piece of design, and the OS is superb. I'd use a Mac if it had the apps I need.
I just bought a dozen HP ProLiant "server" boxes so I guess we won't be converting to Macs any time soon.

It's just UNIX with a bit of sanity added. :-)
Macs will happily access PC servers, and PCs will happily access Mac servers these days (the only downside being, OK, it's generally not as fast as MacMac or PCPC, but yourself you're routinely moving hundred megabyte files around, you probably won't notice or care). Apple actually uses an open-source implementation of the SAMBA file sharing protocol to pull this off... that must look pretty good on the author's resume, "Implemented SAMBA server code as open-source, free software... later adopted by Apple and shipped on millions of Macs..."
We're going to use the HPs as regular PCs, not as servers. I'm typing on one now. We decided they were just the cleanest and probably most reliable machines we could find, and we wanted everybody in the company to be running the same iron, with a couple of spares around.
John
Yes, I found that at Mouser. Even comes in two colors but unfortunately only in rather large spools. I'd only need 50ft or so at a client and having a drum of 1500ft doesn't make sense. So I'll see if our aircraft maintenance guys have any or I'll just do it with wires.
Digikey is out. They are out of stock on a lot lately, had a real hard time assembling the last part list. I would go to Mouser instead but their search "feature" is the pits. That costs them more business than they'll ever know.

For test fixtures and personal stuff, I really like waxed dental floss. I'd be concerned about using it in production or flight hardware.
Looks like 500yd is the standard put-up for lacing twine. I have a spool of flat braided waxed black nylon twine that I've been using for years... still have bunches on it. If you would like, I can spool off 50ft or so and send to you. Email your mailing address if so.

Silly question, but why is the wax important? (I've never done any string lacing myself...)
And the interviewer says, "So, it says here that you work for free..." ;-)

"lacing"
...
Go to the avionics shop and ask them if they can spare 50 feet of flight line and a bucket of prop wash. ;-)
Cheers! Rich
ISTR that it holds the knots tight when tension is released. ( but I havn't used lacing cord for over 25 years)
martin
Yup. Square knots stay nice and tight.
