hi all

does anyone use hairpin-style cotters instead of standard cotter pins or rings on various parts like turnbuckles, lifelines, celvis pins, etc?



rings seem safest, and least prone to snag, but I like the ease of removability of the hairpins (also a disadvantage, of course)

are there any other cotter styles out there?

lastly, anyone know a good source for split-ring Ronstan-type cotter rings (decreasing diameter)? I have been searching everywhere, but not found a good source - most seem to be parallel-diameter style - I find the Ronstan-type much easier to install

thanks!

The hairpin is easiest to remove and snag, and therefore the least secure. I used them for things like my day sailer rudder pintle. I'd never use it for standing rigging. On open-body turnbuckles, I used straight bronze pins and wrapped the tails around the body. I used rings on most clevis pins. It's security vs. ease of removal. I haven't tried the rues.

understood, thanks guys

I have also done SS wire, through T-bolt hols, and wrapped around body - thoughts?

meanwhile, I will stick to the split-ring Ronstan-style, unless the bowtie turns out to be equally secure (I like that it has a longer lever-arm to prevent turning of the turnbuckle)

Rolf, here are a couple of sources for the easily-removable cotter rings:

http://www.downwindmarine.com/Cotter-Pins-amp-Rings-p-1-c-6248.html

and:

http://www.westmarine.com/buy/west-marine--stainless-steel-cotter-rings--P002_060_010_004

The hairpins are OK for things that need to be frequently or easily removable, but they would be hazardous in most applications on a sailboat. Any kind of easily-removable pin - including cotter-rings - need to be used with caution and checked regularly. I use cotter-rings to attach my shrouds, because I drop my mast from time to time, but I've had them snag on the jib sheets and have had to replace one now and then. I use them at a lot of other places where they aren't subject to snagging, but I check them all from time to time because I had one nearly wear through (they are thin wire, after all). Just be cautious with them.
The trouble with a destination - any destination, really - is that it interrupts The Journey.

I have sometmes used SS wire for my turnbuckles, b/c 1) I can choose the guage/thickness; 2) I can cut to size; 3) I can tuck the tails into the turnbuckle, so nothing's snaggable; 4) it's cheap

any reason not to keep doing that? what is standard turnbuckle practice? cotter pin? and is that b/c it's thicker guage than a cotter ring, or wire?

wouldn't a bow tie be even thicker than straight pin, and less snaggable?
