[rebel-builders] Nicopress sleeves

[Bob and Olga Johnson]

Hi Ted. I do not know numbers, but the sleeves Murphy supplies with the
Rebel for the 1/8 cable are copper alloy approx. 5/8 long and three squeezes
are close but not a problem. This has been typical with the four Rebels and
one Moose I have worked on. Bob J

I recall reading that the correct sleeves for stainless cable are the
zinc plated copper ones (AC43-13B I think). No significant difference in
price but MAM ships plain ones AFAIK. My inspector did not care and had
never heard of a corrosion issue. At least one guy here did have an
inspector that cared. Might have been Nigel in the UK.

All 1/8" cable nicopress sleeves require 3 crimps AFAIK. All inpectores
should care about that. The sleeves are only about 9/16" long as you
observe. As long as you do the center squeeze first, it will expand the
sleeve (lengthen it) enough for the other two crimps.

Questions on the length & material for my nicropress sleeves. Aircraft
Spruce has two part #'s
(http://www.aircraftspruce.com/catalog/a ... opress.php ) 18-3-M &
28-3-M with the first being standard copper and the latter being zinc plated
copper. My 1/8" 7x19 cable is stainless steel. The book on the sleeve
swager (http://www.loosnaples.com/oval-sleeves- ... pr-51.html ) lists
a stainless sleeve. What material should I be using?



The book on the hand swager I have
(http://www.loosnaples.com/how-to-use-a-1-sc-pg-3.html ) recommends 3 swages
for 1/8" cable. The 18-3-M (I'm assuming that's the part #'s of what I
have; I got them a couple of years ago) copper ovals I do have are 9/16"
long. These do not appear long enough such that after I do the first,
middle, compression there will be enough room left for additional
compressions fore and aft (for a total of 3 of course).



I have some existing aileron cables that I am redoing (that's what prompts
these questions). Their sleeves have only two swages, and the sleeves
appear to be the same length as the existing blanks that I already have.
Hence, another reason why I'm concerned that there is a longer sleeve
available that would be used for applications requiring 3 swages.



Input please.



Thank you,



Ted

I bought copper sleeves from a local industrial supply house when I was
rigging my skis.

You're right Ken. It was me. Can't remember exactly where it said now, might
be AC43, but the zinc plated ones are the correct ones to use with SS
cables, and the PFA wanted me to fit those.
Having said that, the most important thing is that they are correctly
crimped and my inspector mentioned that he has never seen a badly corroded
copper one on the many certified light aircraft he's worked on in the past.
