Proper swaging of the sleeves is proven by measuring the compression
of the sleeve with a go/no go gage. $20 is pretty cheap insurance for
a beam needing a truss.

Cable clamps on Phillystran need to be torqued to spec a few times
over a period of days to insure they completely cut through the PE and
are bearing on the Kevlar. I've had them slip when this was not done
and the PE creeps. Also clips are not recommended for larger size
Philly.

I'd be pretty surprised by a properly applied (checked with gauge, or
calibrated crimper) swage slipping. The cable would break first. I don't
think I've ever had one fail, except when I used the wrong size sleeve
for the cable, or was trying an "improvised crimper" (like bench vise..
please don't judge me, it's all i had at the time). If you have the
right dies in the crimper, it's almost impossible to get it crimped
wrong, because the "crush" is entirely set by the notches in the dies.
The swage checker is a good check for things like "someone interrupted
me while I was crimping" or "something looked like it was going to fall
off the bucket, while I'm up in the swaying bucket truck in the wind"

I also have used the alunimum double barrel press sleeves from
Tractor Supply. I have used them for Boom Supports and end post
corner supports.. I have has failures on my f-12 30/40 meter
beam the boom truss failed ☹ I have since gone back to the
phillystran and SS cable clamps..

Subject: [TowerTalk] Cable Work
No real qualifications here, but when did that keep me from offering
advice!
In prep for some tower work which didn't happen, I bought some 3/16
aircraft cable and sleeves online.
Not wanting to pay for the real deal tools, I bought a fence wire
swaging tool at Tractor Supply. I expect all the places, like Agri
Supply have them.
I'm not sure if I actually verified the die diameter or not, but must
have thought it was OK.
I have since done a dozen or so swages, to make slings for logging
and general lifting with my tractor boom.
Since they are just a few feet long, I consider the slings expendable
and abuse them accordingly.
I have no idea what loads I've put them to, but I have lifted/pulled
some BIG logs.
None of the swages has slipped at all.
I probably wouldn't put up an expensive tower/beam with this stuff,
but I sure would put up a cheap one.
As usual, YMMV and I'm not making any promises, but I've been amazed
what the stuff can do.
AND these are single sleeves, not the doubles I'd use on a tower.
WL
