Re: Replace standing rigging?

the fitting is a nico press fitting it is used a lot on smaller boats. and contrary to what most people believe, it is the stronger of the wire rope fittings. they will hold 100% of the wire rated load. don,t have the corrosion problems of the ss swage fittings. the wire will break from fatigue well before the nico will let go. there are many types of crimpers for these fittings and no matter which one is used the crimp is checked with a gauge to make sure they are crimped properly. on the larger wire that you have the nico takes three crimps with the tool on each sleeve and sometimes the uneven spacing make the crimp curve a little and this is not a problem and does not effect the strength. the thimble will always touch the nico sleeve when there is no load on the wire because the 1/19 wire is trying to be straight and forces the thimble into the sleeve. on both the marine and aircraft cables that I have made I cut off some of the thimble ends to make a smoother transition and prevent the ends from getting bent over time. this procedure is standard on the aircraft cables and the FAA approved method.
