2135.0. "Cracked Swaged Fittings" by MPGS::HO () Fri Jun 10 1994 14:54

    After taking the cover off my mast last night I was expensively
    surprised to find that three swages on the standing rigging had cracked
    over the winter.  Both lowers and the forestay.  The bottom swage in
    each case.
    
    Such ingratitude after being babied indoors all winter and
    most of the spring.  But nothing that a massive (for me) infusion of
    money can't fix.
    
    Does anyone have any suggestions for extending the life of swaged
    fittings?  Or should I simply live with a 24 year MTBF?

    Come on Gene, where are the smiley faces???   ;>)
    
    Most books I have read said to replace standing rigging every 8 years.
    Now here in New England with our 12 week "season" we can extend that
    a bit, but 24 years???
    
    I have heard of people dousing the fitting with wd40 periodically, but
    I wouldn't want to chance it making the connector slip or staining my
    gelcoat.
    
    I hope you are going to replace them all. where 3 let go together,  how
    far can all the others of the set be? Cheaper than having to cut the
    new ones off to get rid of the mast rig because one of the originals lets go
    in 3-4 weeks.
    
    Time to pay the piper.....  ;>(
2135.2WD40 for Water protectionDPDMAI::CLEVELANDGrounded on The RockMon Jun 13 1994 12:436
    The WD40 won't make your connector slip unless you're already in Deep
    Doo-doo, in which case the WD40 doesn't make a difference. What the
    WD40 does is displace water and coat anything down in the swage fitting
    that could rust and break. It's not a bad habit to get into doing...

    I was recently in a conversation with a friedn who maintained that
    there is a new swaging technique available, where one uses en epoxy to
    hold the wire to the fitting.  Apparently it is something like the
    norseman/stalock type but without the cone.
    
    I know that norseman/stalock are stronger and more resilient than
    regular sawging so that says quite a bit.

re .3:

Castlok fittings have been around for quite some time. According to 
Practical Sailor, they're equivalent to Stalok and Norseman fittings. 
The drawback to Castlok fittings is the time required for the epoxy to 
cure and the need to degrease the fitting prior to assembly.

    	I'm a big epoxy fan myself, but the stuff will eventually harden to
    the brittle stage at the extremities, so a little expansion/contraction
    of the swage joint and poof! microcracks, them water. Now, in 24 years,
    I'll betcha rust comes into the equation as well, no matter what you
    get in there. I try to use WD40, gravity and prayers myself. 
    
    	A new sail is more than shrouds, ain't it?
    
    	$$$ time!

    Gene,
    
    Cut off the old ends and swage on new ones. For your boat, the rigging
    will end up 8" - 10" shorter. But this can be taken up easily at the
    turnbuckle end by adding about half a dozen toggles. 
    
    I'll guess that buying new shroud cable for your boat will be at
    least $150-$200. You can get six toggles for have that cost.
    
    And there's no end to the number of times you can do this. Eventually
    you'll have all-toggle standing rigging (and the slowest boat in the
    fleet). This new rig will look good next to your vang lashed onto the
    boom with string and the wet-noodle spinnaker pole wrapped with fiberglass
    reinforcement.
    
    Seriously, poor old Touche' has been a faithful old mistress. Quit
    belly-achin' and dump a little money into the old girl.

    All the lower swages did eventually crack.  So we have new standing
    rigging all the way around.  Layline had the best price and delivery.
    Ordered onMonday and the finished shrouds and stays were delivered 
    to my door on Wednesday.  All I had to do was provide the 
    measurements and the plastic.  Very convenient if you can step 
    your own mast.
