break testing...to whip or not to whip?

Lockstitch only, if that. I don't see a reason to whip it down.

...except, I wonder if a tight whiplock could actually weaken the splice... meh, I don't know what I'm talking about.
 
Assume you're talking about whipped splices. I've always whipped splices ... taken some crap about it being a waste of time. It would be great to know if it is. Probably will still whip splices though, just because it looks better ... a more professional finish. Definitely "worth doing!"

Whipping alone to form an eye (instead of a splice) is called 'seizing'. Brion Toss once wrote of seizings; "... they're so strong and secure that they rival Eye Splices." (Brion Toss, Chapman's Nautical Guides, Knots, 1990, p161)

It would be great to see some testing of that, too. But, that might be hoping for too much. Any testing along these lines will be much appreciated, thanks!!!
 
I does look cool. But, perhaps I mis-interpreted trevmcrev's intent.

I assumed (hoped) the testing would establish the value of whipping beyond its cool factor.

ah-oh, did I just say that ... this thread could take a bad turn ...

I guess my intentions are mixed.

1. Would be interesting to see if there is a strength difference, but isn't it only really for preventing creep under no/low load.
2. I like the finished look of a whipped splice, but hate doing it. I have a bunch of things to make n break and don't want to waste my time if i dont need to.

Maybe i'll go half/half & see what happens....

Yep, I whiplock everything... if for no other reason than it looks cool. But for break testing it seems like a waste.

I think the opposite would be true. The whipping drastically changes how the splice reacts under high loads. The whipping can something HINDER your results as it doesn't allow the splice to "settle" in under those high loads.

So since your whipping is part of your splice in the field, I think you owe it to yourself to test it that way. You should test however you'd actually use it.

So for me, most of my splices are not "whip locked" they are stitched (using my non patented NICCS Method). When I test, I test with that same stitch method to make sure there is consistency from test results to usable product.

Good point Nick about consistency. I usually whip everything, even my break pieces, but Im taking some monday to break and I only did a 2 pass stitch simply to prevent creeping, I am interested in un-hindered splices on these and dont want the stitch to play any sort of role.
 
Hi,
It is possible to deform -- and thus weaken -- a splice with a badly-done whipping or stitching. Just remember, the point is not to make the splice stronger, but to keep it from crawling apart under LOW loads or shock loads.
As for seizings, they are distinctly not the same thing as whippings; think of them as cable clamps for rope. Done correctly, they can approach 100% efficiency in wire, and in some ropes, but Spectra, for instance, is way too slick, even if served first.
Fair leads,
Brion Toss
 
Oy,
Will have to did those results out. As I recall, we never got much past 50%, even with very long (5" or more) seizings, made extremely tight, in both Spectra and nylon, with and without service under the seizing. Spectra is weirdly slippery stuff.
Fair leads,
Brion Toss
