Hi folks, when I dropped my mast to install my new headstay/furler a couple of weeks ago I noticed that the uppers were not attached to the spreaders with the stainless steel wire as shown in the factory drawings. where can one purchase a small roll of wire? What size do I need. My C22 uppers were held in place by a cotter pin. Would this method be OK if I don't find wire? I have to haul my boat out for the winter in a couple of weeks and then will start another round of upgrades.
Thanks Clam, You da man. Now I'm wondering what Monel really is. Is it like polyunsaturated stainless? I'm assuming it is some kind of an alloy, like most metals are.
Monel isn't stainless and will rust. So, maybe not the best choice for holding upper shrouds to spreader tips.
If you have a rigger in your area, see if you can buy 6" of 1x9 stainless steel wire. Each individual strand should work well for your purpose......as well as locking turnbuckle barrels to bolts, etc.
Bill, why do you think Monel will rust? As far as I know, it's superior to 'garden variety' stainless, especially if you want to wrap something with it.
I think the 'regular' stainless from a piece of spreader wire will be pretty darn springy. It has a LOT of memory and will fight you tooth and nail... wherever it kinks, it's subject to breakage.
I think that is why WM (and almost every other rigging shop) offers Monel alloy wire specifically engineered for seizing... you can easily bend it, wrap it, etc... and it will stay.
At any rate, here's a blivet from one of the many metal suppliers pages revealed via google.
-------------- Monel... offers high tensile strength in a Nickel/Copper alloy highly resistant to atmospheric corrosion, salt water and a variety of acid and alkaline solutions. Used in marine engineering, chemical and hydrocarbon processing equipment, valves, pumps and heat exchangers.
Because of its good corrosion resistance it is also widely used in chemical plant equipment. -------------
Go to a metal fabrication supply house, the kind of shop that sells sheet metal, tubing, aluminum, etc., and buy a 1 pound spool of .032" diameter ASTM Type 304 stainless safety wire. This is at least a couple hundred feet of wire, enough to last you the rest of your life most likely. You can use it for wiring upper shrouds to spreaders, securing anchor shackle pins, and lots of other tying purposes. Cost for the 1 pound spool will be about $15.00 and it will probably come packaged in a cardboard canister about the size and shape of a soda can.

The reason I think that Monel will rust is that I use it for both seizing wire on my anchors and to stop my turnbuckles from "backing out". In both useages, the Monel wire rusts after about 15 months and needs to be replaced.
Bill, your bad experience is certainly worth noting... proof is in the pudding.
I am curious, were your problem based on using wire from a single brand or roll of wire? (possible bad stock)
Also, what was the nature of the corrosion? Was the monel getting a brown copper hue (normal) or did it actually begin to disintigrate and fall apart?
At any rate, the ASTM Type 304 stainless safety wire Larry suggests should do the job nicely and will be lots cheaper without the 'marine' word in the name.

Are you in an area where there are serious fishermen? Go to a large tackle supply place and you will find various forms of leader wire and trolling wire. I used these for years to wire shackles (you can also get galvanized)and I think you will find what you want. Fair Winds, ron srsk Orion SW FL
