I used a manual swaging tool to make new guys for extending an AB-577 to
75'. Although visual inspection isn't conclusive, I couldn't see any
difference between the manually swaged sleeves and the ones on the stock
guys that had been swaged by machine. The manually swaged sleeves held up
fine supporting a 4-el SteppIR in New England weather conditions for a
couple of years.
That said, the breaking strength for the 1/8" stainless wire rope used for
AB-577 guys is only 1760 lbs. It seems likely that a manually swaged sleeve,
if done properly, would exceed that.
