Jim,
My failure on pressed sleeves was on a hand crimping tool and double barrel alunimum frerrels.
I have used cable slings @ Bethlehem Steel ( when I worked there ) on Nile 50T with 75K loads with Swedged PRESS installed fittings No problem
MY failure was NOT on any factory but the kit and parts sold at Tractor supply
In the past I have re-strung crankups towers both single and postitive pullup/down cable design and used a local wirerope distruubitor to duplacate the cable length, .thimble and swedging configuration

<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.

## say what ? I guyed a 82 foot tower with 3 yagis on top, back in the 70s, using winch cable, insulators and nicropress crimps, zero issues.
US Tower corp uses nicropress crimps on all their cable assys. My Hdx-689, weighs 5600 lbs, loaded.
Nicropress crimps also used on both my cum-alongs, zero issues.
40 ton cranes also use crimps, zero issues.
75 ton HD rotators, like the real big tow truck rigs, used to haul a semi out of the ditch, will also use crimps, typ with .75 inch
and also 1 inch cable.
## as long as they are properly installed, they are not an issue. The cable will always break 1st.
## Never had a problem with subsequent towers, where 7 strand EHS and pre-form grips used. Again, they have to be installed correctly,
again the cable will break 1st, never the pre-forms.
