[rebel-builders] Nicopress sleeves Copper

The FAA in their wisdom does say in AC-43.13 Copper only for primary
flight control cables for Nicopress Spruce 18-3-M 1/8" on pg 137 should
be acceptable.

Subject: [rebel-builders] Nicopress sleeves

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
