Corky... the swages must still be checked against a "go - nogo" criteria ..
measuring tool..
We had a control cable here that came apart in-flight, swage failed.. a tool
was used that had previously been determined to produce substandard swages..
it was kept around for some reason.. another mechanic used it a couple years
later on an aircraft and did not check the go/nogo,
the aileron cable came apart.. the pilot was able to emergency land in the
desert with no major damage.. rudder/elevator only..
the mechanic was fired.. and a letter put in his FAA folder..

Note that there is also available an "economy swaging tool" (see Aircraft
Spruce catalog P/N 12-12000) for $15.95. It takes more time to do the
swage
(you tighten bolts to swage the sleeve) but that's not a big problem
unless
you work on an assembly line and have hundreds of these things to do.
This tool has been recommended in the "canard pusher" newsletter.
Has anybody any comments on this? Are there any potential problems with
picky inspectors?
I have this tool and confirm that it does what it's supposed to do. I
think it's insane to buy the expensive tool when the less expensive
one does the job precisely as well as the more expensive one, it just
takes longer.
Please note, there is no difference in the resultant swaged cable end
whether using the cheap tool or the expensive one, the end result is
exactly, repeat, exactly the same. In fact, I borrowed the expensive
tool once and had to discard the parts because the owner called me up
later and told me that he'd been contacted by the manufacturer and was
told that the tool had been improperly manufactured and could produce
substandard swages. So the cheap tool worked better than the
expensive one.
If you tighten the bolts till the two halves of the cheap swaging tool
bottom out together, how can the result be any different than the more
expensive tool?
