Yep. You could accomplish the same thing with some #10 copper:-) I think rings are probably a better idea than cotter pins which require pliers every time you need to adjust a shroud/stay.

Re: Replace cotter pins with welding rod

I like rings too, basically because of no sharp points, but they CAN unwind on their own. They can also get bent which makes them a bitch to remove.

This welding rod idea is interesting - eliminates the need for rigging tape with its downsides. A small roll on board means you're never out of the right size pin as well. It's essentially a variation on safety wiring bolts.

P.S. If you follow Rod Stephens advice you don't need to replace cotters every time you remove them. Clip them short - just enough length to get a decent end on them, then spread them about ten degrees or so. They don't need to be wrapped back on themselves to stay in place. The small spread on a short end will keep them just as secure and squeezing them with pliers to remove them flattens the end enough to be reusable.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: Replace cotter pins with welding rod

The only thing I'm scratching my head over is what about fine tuning adjustments?

So, you've got the rod bent at exactly the right spots but realize you need to tighten up the shroud a couple of turns -- now you've got to re-bend the rod (or replace the whole section)

Maybe I'm over-thinking it...

Re: Replace cotter pins with welding rod

I've done this for the last 25,000 odd miles and it has worked great. There is some further discussion of it here with a photo of Rod Stephens and details of his cotter pin recommendations.

Turnbuckle protection - SailboatOwners.com

I've had cotter rings snag on jib sheets and get opened up into finger snags. Never a problem with the welding rod. I also like the looks of the rod better than the rings.

There is no tape on my boat except the upper headstay fitting which a boat yard worker put on and I didn't notice.

When a rig comes down I wouldn't want to have to unscrew the bottle screw - you need more tools for that and it takes too long. It would make more sense to take the pin out of the bottom of the bottle screw where it connects to the chain plate. I don't believe welding wire down there is a better idea.

The intention of these pins is to stop the bottle screw from unscrewing itself. The good thing about the wire is that it passes from one cavity to the next so there is no way that the bottle screw can do more than a quarter of a turn because the wire goes tight. If the split pins (sorry I can't call them cotter pins) are a little small they don't achieve the primary objective - the bottle screw can turn past them.

I like the sound of the Silicon Bronze option. I guess I'm showing my age but a bit of ye olde worlde patina sounds like no bad thing.

You are. I've taken up a couple of turns on mine with no need to re-bend. I've also re-bent to accommodate a new length very quickly with a pair of needle nose pliers.

Very good point, and it's a concern with my particular turnbuckles. The typical open turnbuckle has that crossbar at the midpoint, which allows the wire to prevent rotation of the turnbuckle:


But I have the Catalina OEM turnbuckles, which are an unplated bronze inner turnbuckle with no crossbar. I like them because I don't need rigging tape - the SS cover accomplishes that nicely. But without the crossbar, I'd be afraid that a tightly bent wire would allow the turnbuckle to rotate:


So unless I replace my turnbuckles someday, I think I need to stick with the split pins that are used currently.

Re: Replace cotter pins with welding rod

My previous boat had the TIG (?) wire in place of cotter pins. It worked great for several years of day sailing and short cruises in inland waters.

For the record, it was purchased in welding sticks or rods, not from a spool. I've never done more than spot welding so I can't comment on the variations of wire.

I have cotter pins at the moment, but will change over to welding wire as I have to change out the pins.

So much easier to make small adjustments and much less work when the rig comes down for the winter.

YMMV

Edit: Got me to thinking.... RIP Tom Rapp of TR Rigging.. you were a nice guy and missed. http://www.legacy.com/obituaries/tim...21#fbLoggedOut
