Eye splice in 4-strand?

ah, yea, I had missed that vid in your post . . .yea that's exactly an example of the '2-strand end-to-end loop' approach.

Since, having lived in Germany and now Portugal for years and having to speak the lingo despite having no natural talent, I am completely immune to shame in my feeble attempts - here are some photos of this weeks 3-splice eye-splicing attempts


The 4-strand sequel will be in a cinema near you soon!

Not bad.. now just follow the same routine for the 4 strand.
Have a go at tapering the end down..

[Malagueta]

Is the tapering just for aesthetics or does it reduce the stress concentration where the splice ends?


Or is it for something else?

Partly aesthetic, partly practical..
Dock lines can be made to look prettier by tapering but not crucial..
Main, Foresail halyards however the taper makes jamming in the sheave at the top of the mast less likely.. but even that depends on how high your sails go, and it gives more strength to my mind.. but that's only my mind.
Others may differ..

OK,
still havent found time to try the 4-strand, but ...
I had to take out the splice in the three strand I did and the rope has become 'kinked' where I took it out
Its symetrical in all 3 strands

I dont know what this is called, so cant search for it
How can I get this out
I can make it worse by untwisting the 3-strand ....

[Breaking Waves]

It is called a 'Hockle" - usually, you can twist it out.

Unless you have somehow put it in structurally with your splice and unsplice.

Thanks!

Seems its called a 'Cockle' in UK

interesting - "divided by a common language" - again lol.

[Malagueta]

Or is it more complex than that?

[open quote]
What is a Kink? A Cockle? A Knuckle? A Hockle? and a Chinckle? How do they affect a rope?
A kink is an abrupt bend or loop in a rope which is a result of an unbalanced twist relationship in the rope structure.
Strand kinks are also termed as cockles, or knuckles.
A hockle is a condition whereby a rope strand twists on itself -- also called a chinckle.
Apart from the effect on the strength of the rope, kinks and cockles are detrimental because they interfere with the utility of the rope. They will not pass through a block, will not lie properly, and will chafe more readily.

And, finally .....


I did two over and then the other two under to start


This was my first attempt
not as hard as I was fearing


worst bit was it is nylon with fine fibres that kept getting stuck to my rough hands like velcro


Also there was a thin core strand that got a bit in the way, but generally not that difficult


The rope strands easily 'unwound' and I think the fisherman's video way would have been a nightmare with this floppy nylon rope - perhaps easier with polypropylene

The Samson guide for 3-strand said to count 16 crowns/picks from the end to unlay, so I did (4/3) * 16 ~ 20, but it was probably over-conservative as I ended up with a very long splice



Thanks for all the help!

Those two look pretty good, Malagueta! the second one, it looks like you could have tightened up the first tuck just a bit more (appearance, not structural). It took me MANY tries to get splices that neat!

As an aside, in stranded splices, two tucks will hold, but can shake loose - three tucks is enough in 99.1% of cases, and 4 tucks is all you really need (unless you want a long splice for some reason). I've made some extra-long splices in my docklines so the end of the splice is NOT at the max friction point.
If heavy shaking/flailing is a worry, just whip the splice or make a cover and sew it down tight. I've made a couple leather covers for my dockline splices - not sure they do much, but they look nice!

(a) is essentially the same as with 3 strand - take the 4 strands around the intended loop, put two on top of the standing part and 3 under, and tuck 'against the braid' in order, (b) is essentially to take two strands up one side of the loop and the other two strands up the other side and make a 2 strand end to end splice at the top of the loop, with the tails long enough to continue the splice a few tucks into the standing part.

Are there other/additional fundamentally different ways?

(I dont have ashley at hand).

You can download ABOK from numerous sources. Internet Archive is good.

I haven't seen any 4 strand laid rope in a long time but I prefer to first Flemish the eye and then tuck it on out against the lay as per normal 3 strand. Flemishing the eye makes starting the tucks much less a concern. Just tuck each end under the nearest standing part strand. No drama and no mystery.
