wheels 543 Posted June 9, 2012 Share Posted June 9, 2012 It depends completely on what the rust is. Galv is Zinc alloy and in air, does not rust of course. But in a corroding situation, it works by sacrificing itself just like the anodes do. So rust is actually a sign that the Zinc has actually disappeared and the steel below is being exposed. Oiling the wire simply adds another level of protection to the wire and to the Galv coating. So if you are getting a Rust problem, then treating the Rust and then coating with a Zinc rich primer is the best practice. The benefit with Galv wire is that the Steel has a certain amount of elasticity and so under cyclic loading, happily stretches and pulls back to original again, without being detrimental to the strength of the wire. It does tend to need retensioning every now and then, but that is no biggy. I have both SST and Galv rigging and the Galv rigging is crimped with Ally crimps and at 15y old, still looks pretty new. SST does not like cyclic stress loading. Because it is an alloy of some very hard metals, they don't like playing well together and it does two things. It work hardens, which in itself causes stress and it cracks by just the very hard metals not wanting to hold on well together. Both stresses cause a cracking issue and the big problem is that the SST can lok lovely shiney and new right up to the point of failure and it tends to go with no warning. Galv tends to fail slowly. One strand at a time over time. When a strand of SST goes, you hear a "ting" sound, usually followed about 3 to 5 seconds later by "BANG" Link to post Share on other sites
Guest Posted June 9, 2012 Share Posted June 9, 2012 Well gal sounds the ants pants to me. Surely there's better stuff to treat it with than lanolin! Maybe expose for a while and then place in a tub of zinc paint? I know k1w1's get off on the smell of sheep but surely tech has moved along. Link to post Share on other sites
rigger 47 Posted June 9, 2012 Share Posted June 9, 2012 for wires that do not have something sliding up and down them try serving them. Used to use fish oil on the rest, though you could go for a mix of SS and galv, SS where sails run up and down, shrouds / backstays use galv. pic of served wires Link to post Share on other sites
Steve Pope 243 Posted June 10, 2012 Share Posted June 10, 2012 Wow!! Rigger that is impressive, who does serving like that?? Link to post Share on other sites
rigger 47 Posted June 10, 2012 Share Posted June 10, 2012 I have other photos showing how we did it but cannot pubish on the web. If you want to see the rigging close up take a wander to the Maritime museum and look at the Breeze, or go on the SoNZ. The rigger involved also did a few small bits on Waitangi awhile ago.

Guest Posted June 11, 2012 Share Posted June 11, 2012 There are some specialist wire rope lubes and coating available. Some lanolin based just for the Naki lads to remind them of their special ladies Link to post Share on other sites
Rats 28 Posted June 11, 2012 Share Posted June 11, 2012 Wow thats a serious serving job..... can you enlighten me as to how it was served... with a serving mallet for instance?.... materials used and coating if any? Link to post Share on other sites
Guest Posted June 11, 2012 Share Posted June 11, 2012 Drizzled with Walnut oil along with sides of Truffle mashed potato, Honey Carrots, Cabernet Jus and we better knot forget the Raisin & Almond Caper salad. Link to post Share on other sites

Coated in a black tar substance, parceled with canvas and served with synthetic braid using a serving mallet, assisted with a chain block, swivel and motor vehicle. On this job I was only involved in part of the work (planning/ measuring / chceking) and mostly as an extra hand, the other guys deserve the credit for a great job. Link to post Share on other sites

Sure Riggers option does have a lot more dietary fibre but mines more tasty and multipurpose, mine also has oil PS to Rigger. I can assure you that you can tenderise a synthetic braid as much as you like with any sort of mallet but it will still be tuff Link to post Share on other sites
