We got one of these leash rings and tied the stopper they way the website said the another stopper butted up to that one with the tail you tie into thinking this would stop tail slippage. What happened what both stoppers sinched together while someone was on the highline and made slack around the ring. The leash then popped off the ring but somone on the ground spotted it and nothing bad happened. We had to cut the knots out of the rope because they were to tight to undo. We learnt dont try and be smarter than the internet.
Im not sure how that would happen unless someone grabbed knot and pulled it down to stopper knot a little then whipped a few times. Im not sure if that "dont be try to be smarter than internet" phrase applies. I like kolya but i doubt he has done sufficient testing to not be questioned.
HowNOTtoHIGHLINE what he’s describing seems to be a fisherman’s knot - stopper into tail around standing end as per instructions, and then another stopper in the standing end around the tail. Which should have the same effect as the figure 8 stopper you showed, which did indeed result in the ring popping out in your test.
I suppose instead of an open ring you can use a pipe then it cant fall off right? So like a circle of pipe with a open end for the rope to enter, hope that makes sense.
The vortex from Slack Inov is similar to that. It is twice the metal and then it still isnt soft to land on. I like how rope is what you hit if you hit leash ring. I wouldnt be opposed to a ring like your describing though
@@HowNOT2 OH yeah just looked that up that's exactly what I imagined. I hope my channels grows as big as yours and we can collab one day =] lol love the content!
Have you thought about using a wide barrel to wrap you test sample around instead of that weak figure eight ? This way you'd get close to full strenght on one side of the rope, therefore (you shouldn't ...) braking the side you're actually testing :)
I didnt do the same knot on both ends because i just wanted to demonstrate and test if the barrel knot is stronger than how we tie in with our harnesses.
re. 10:20 & 14:46 FWIW, the Fig-8 knot at the left is deforming because it was not carefully contoured in either rope. The first bend should be as close to the restraining parts of the knot as possible. The 'bulging' segment of line should have been placed farther left in the knot. This misplacement will lead to premature failure under these extraordinary loads. I am intrigued by this configuration for this low load, high risk function. I can see that the round thimble (rather than traditional, nautical teardrop thimble) seems to be causing the main line to force open the barrel, which is probably why it tends to creep under repeated loading. re. 15:25 If you watched the film, the tape is deformed not because the tail pulled in (only about ~1/8in or 2 mantle strands), but because the standing line pulled outward several inches as should be expected. re. 16:32 Pointless idea given the perfect tail behavior seen above. Poorly dressed but better loaded fig-8, unlike the pulling end knot. re 20:59 Again, it is easy to untie the overhand, because as noted before, the tail moved almost NONE (less than one mantle strand). Please watch it carefully in the video. Only the live end of the barrel knot migrated significantly under this single loading, not the tail. Suggestion: Do not test this system to outrageous failure loads. Test the knot & thimble behavior under hundreds of repeated body fall loads. Consider a standard or at least pear shaped thimble.
Good info. I like that you get to test your theories and figure out what works and what doesn’t. It seems as though figure 8s break around 11kn. Is the bowline knot stronger or does it break at around the same force.
Why not test it with the webbing over the rope on your test rig? I feel that there is a possibility the rope would act different if there is slick plastic webbing around it.
because threaded rope costs money and it we already did leash break tests with them and know how they break. It would only give us improved numbers if we used a threaded leash.
HowNOTtoHIGHLINE AFAICT The hangman’s being bigger is mostly cosmetic, because it’s mostly about more turns (and three is clearly super good enough). That said, the forces involved in dropping a persons body weight onto a tightening loop do rather closely match the physics of hanging (he said lugubriously), so who knows, might be worth a try.
Why not a figure of 9? Which can take way more pressure than a 8 can ever do :) Why use a round ring directly putting pressure on a single 4cm of rope, when you can have a box section slider which will distribute the load more evenly when in contact with the slackline rope, Just make sure you get it M,P,I inspected first!
we will test figure 8s vs figure 9s on slacksnap. I doubt it makes a difference. The webbing curves enough to put force on the entire ring/webbing. A box shape seems odd to use.
Con you actually wear out a normal leash ring? (By normal i mean 2 medium size rings attached themselves with electrical tape) so, can just walking and whiping wear it out until it is not safe to use anyone? Or is just one of these things you'll get tired of before they show any wear signals
I really like these, but for me there is still one question: could there be a situation where they would unsinch, and cause the leash to be cut before anyone notices? If the answer is no, then sign me up. Any ideas on how to test this/make sure it cant happen?
It is something you will be able to notice and once the knot cinches down it wont come off. If you use any other knot system then you risk it coming off. If it jumps off it is unlikely to cut all the way through a leash in one whip unless you were on a super super loose line and slide 30 meters. I have taken a whip on nothing but the knot loop twice in my life just because i was curious and the rope had a nic in it but that was it.

you could take an 11mm dynema rope and splice the ring, cover it with tubular fabric as protection. (taper the slice) in reality, there can be a much higher force on the safety line. en.wikipedia.org/wiki/Fall_factor#Impact_force

Super breaking machine! Have you thought to do one for fatigue / repetitive loading breaking tests ? Thanks for sharing your work and experience :)
That requires a hydraulic system that can be set up to run automatically for hours or days. Im not there yet :)

For someone who watched the film as carefully as you obviously did, it’s absolutely astonishing how little you understood what he was saying.

Is there really any advantage to the 3rd wrap on the barrel knot? seems like the typical 2 wraps is just as good, right?
How does the back up help??
Hey, it would be nice if you could test the Vortex 2, from SlackInov to update this topic
Vortex 2 is awesome. It’s the only leash ring I use now.
Why not ring the harness side?? Easy clip in too

Hey try the hangman's noose knot I'd like to see what that does for that ring application.

Where do you buy rings

a box would break a lot faster than a ring, the pressure on a ring is distributed the best it can be.

Your leash itself will wear out 100x before 2 steel rings will. I also dont think this ring would wear out from use either.
I really like these, but for me there is still one question: could there be a situation where they would unsinch, and cause the leash to be cut before anyone notices? If the answer is no, then sign me up. Any ideas on how to test this/make sure it cant happen?

Sounds good :)
you could add a knot to the 'slipping' line to make sure the slipknot cannot move further off the ring.

I don't get more than 2kn on my rings.... 10:1 safety ratio!

what about when everithing gets wet?
found a old but intresting script about that topic
www.itrsonline.org/PapersFolder/2011/Kovach2011_ITRSPaper.pdf
would be intresting see a video of you guys testing these things on your nice set up
i can test wet vs dry rope. That article had too many words. We need videos and dramatic guys to make that way more interesting.
Looking for info to share with my grandkids, watched right up until I read the shirt.
olegig don’t be a boner. It’s a word, that your grand kids probably already know and use
What a fucking pussie
And the frog is cooked.
you could take an 11mm dynema rope and splice the ring, cover it with tubular fabric as protection. (taper the slice)
in reality, there can be a much higher force on the safety line.
en.wikipedia.org/wiki/Fall_factor#Impact_force
the trick is it gets better tight around the ring during the use , so a fixed knot is not recommended
Kilonewtons not kilonewtents
Actually, just kiloNewton, there is no plural form.
cool stuff.
