Same here. They are Merriman chrome bronze open turnbuckles, and have never seen salt water. After 39 years, I am replacing all the stays and a few tangs and toggles, even though they still look good and I do not shy away from carrying plenty of canvas in buckets of wind.

I just figure I owe the boat and fate should not be tempted further. Standing rigging minus turnbuckles (just 1/4" 1 x 19 SS wire and terminals) is just $875 for me...a no-brainer and cheap insurance for the next 20 or so years.

In salt, I would consider 10-15 years to be the maximum obligatory replacement cycle.

With stainless on stainless there better be an anti-sieze or other equivalent to lube the threads. Stainless tends to (gall) weld itself together under stress.
I may be wrong ,but I suspect the graphite used in many anti-sieze compounds and sprays may set up a galvantic circuit between the carbon ( graphite) and the ss or bronze turnbuckles. Just one more thing to worry about.
Gord ,this is your kind of stuff; can you help us out here?

Personally, I use Tuf-Gel or Lanocote! But>>> SailKote Marine Dry Lubricant & Coating for Sails, Rigging, Deck Hardware and more. - McLube

Graphite and stainless (or bronze) is a HUGE problem. This includes molybendium, and other graphite compounds. Much like carbon fiber graphite is at the very top of the galvanic chart, and will cause localized galvanic corrosion at the threads. It is a great lubricant, but should never be used on or near stainless threads.

We are using it on titanium turnbuckles, because they are galvanically compatible. So there is a use for it in standing rigging, but not when the turnbuckles are stainless.

As for what other materials... Well my vote is for titanium rigging, with Dynex Dux replacing the wire, but I am a tad prejudice on the matter.

Re: New Standing Rigging

Exmoor,

Use Lanocote or Tef-Gel on the threads to prevent galling and make them easy to get apart later. As an aside, don't fall into the trap of bigger is better. Upsizing rigging is not a great idea. We see it all the time.

The numbers I've known for sizing rigging (1x19 anyway) is twice the weight of your keel. So if you carry 2 tons of lead, use wire that has a 8,000lb working load. I don't have any backup for that assertion but I've read it in a few books and it's easy for me to remember.

Re: New Standing Rigging

I would much rather see a wire break during a knockdown or rollover than a chainplate pull out of the boat. If the boat has been properly designed, the naval architect calculated appropriate structures and rigging. People who go oversize on rigging add extra weight aloft and may interfere with some safeguards.

Re: New Standing Rigging

Get in touch with your original rigger. Not all riggers are the same.
Before replacing parts of my standing ringing (nitronic50 -10 rod), with the mast down, I had a fortune of original rig designer coming over and spending half a day going over everything. Best 500$ I ever spent.
In my experience, lanocote or tef-gel leave threads sticky and collect dirt, dust, sand, then few years later you try to adjust your rig and all of a sudden your threads get damaged.
I've been using Dry Molly (Molybdenum disulphide) to prevent galling on turnbuckle threads.

+1... Have heard also and seems like a reasonable approach.

Main thing is to use something. I've been using Lanocote for many years without any problem. If it's collected some debris, a rag with solvent can be used to wipe it off before loosening the turnbuckle. I've seen rigs that haven't been touched in 8 years loosen up easily if they have been treated. Dry Molly sounds like a good product. Will look into that.

Re: New Standing Rigging

The OP just wanted to know if he should replace his turnbuckles. You guys want to talk about what to put on the threads. I don't really think it matters if you use anything on the threads. I lube my threads with a little Inox so they don't get hot when tensioning but during their lifetime they will only need retensioning a handful of times, not enough to worry about galling. You might as well replace the turnbuckles unless they look really good, this way you will have all new rigging, not just partially new, but if you need to save money reuse them and just get swaged on studs.
