Hi John-
How much of the tefzel twisted pair wire are you looking for? I had some, might
have a spool. It'll be a week or so before I'm back in town, though.

Subject: | Aluminum bronze - conductivity |
Hi Bob,
Maybe I didn't explain myself well, I'm a bit intrigued by your last
comment. I appreciate that keeping the number of joins down is priceless,
but since stainless is such a poor conductor, I would have expected to need
to bond the stud to something else and not rely on current radiating out
through the thin stainless firewall material? Probably overkill, but I made
mine like the attached photo, which will have a short # 2 CCA fatwire
between the forrest of ground tabs and an engine mounting bolt where there
is chrome-moly structure bolted to a large part of the aluminium airframe.
All of the bonding contact areas on my stud are at least 3/4", while the
main shaft is 3/8 diameter, as are the threads and nuts. There is an
silicone insulating washer on the front and back of the firewall for
vibration absorbption as well.
.... I guess I'll just use di-electric grease to keep the air out at the
point where the stud meets with the firewall, or perhaps make a phenolic
bush to insulate it from the stainless, then bond the stud to a substantial
part of the aluminum structure on the inside (such as an engine mounting
bolt)" ....
"I think clean, grease and lots of pressure are key. Additional
bonding is not useful."

If 22 AWG is suitable for your application, Stein Air sells a variety of colors
of twisted pair (and triples, etc.).
Try this link: http://www.steinair.net/store.cfm?tlcatid=32 and scroll down to
"Wire,Twisted". Or go to http://www.steinair.net, click on "Wire / Coax", and
scroll down the page.

Hadn't seen this one. Your find reminds me that
I haven't a clue as to how this task was handled
at any of TC factories I worked at. I don't recall
that I ever had cause to visit the wire-slingers
for a close look at how they did things. All of
my contact with their work product was after it
got installed on an airplane.
I've still got a badge for Hawker Beech but they
shipped their wire fab shops to Mexico about 10
years ago . . . I'll have to seek insight to those
processes elsewhere but I'll see what I can learn.

I've got a few thousand feet of two
conductor 22AWG shielded. I probably
ought to list it in my catalog. Will
22AWG work for you and how much do you
need?

I'm just looking for 15 ft of UNshielded twisted pair for the RS-422 data
lines in a Dynon D10A installation. If I can't find it, I'll just twist some
22 AWG, but would prefer to have the Tefzel casing for a little added
physical protection.
Shielded I got already. but thank you, -john-
(I wonder if there's tools for stripting three and four wire versions of the
shielded twisted shielded cable?)

I stumbled on it while looking for unshielded tefzel insulated twisted pair
(which I'm still looking for).

Thanks, Joe. Do you 'spose it's Tefzel? I tried calling but I think they're
out flying, today.

Thank you Glen. What I'm hoping to find is a twisted pair of Tefzel 22 AWG
wires inside a out sheath of Tefzel.
Would you let me know, when you can, if that's what you have? thanks,
-john-
