Hey Ryan! Amazing work on destroying every piece of gear we use, so that we feel safer when we highline... I have always wondered about twists on webbing. And if you can test out twisted webbing of different intensity, and see if a half/one twist on a line, reduces the MBS or not and also test a super twisted line(almost like a rope) and see if there is a threshold of twists on a slacklining beyond which the MBS becomes too low to be safe. I'm a little ocd, so I love my highlines to be absolutely straight with no twists. Just wanted to see what happens when webbing is twisted too much
I know im asking the wrong place but does any of you know of a way to log back into an Instagram account?? I stupidly forgot my login password. I appreciate any assistance you can offer me!
@Ashton Merrick thanks for your reply. I found the site through google and im in the hacking process atm. I see it takes a while so I will get back to you later when my account password hopefully is recovered.
You should have broken the sewn loops with a full inov-split, and make it catch on the second shackle to see exactly how it catches, and then broke that.
Do you doubt our slack stoke??? I have 8 pcs of feather pro with sewn loops coming in the mail for us to rig this in the park, attach a leash/rope swing simulation and break the puck out of this in a real real life situation. Then I might just cut a highline... while i'm on it :). Stay tuned. We are just getting started!
Hi I'm loving your videos. Would you be able to use the rope that the soft shackles are made out of to make things like lanyards and rigging lines. What is it strength compare to say 13 mm Beal rescue rope being used as a rope
Another good test to do is put the 5mm inov 8 in the loop, take it to 5Kn, than let it relax, wait some time, do it again to 5Kn, and repeat multiple times. Than break test the loop with inov 8 and see if multiple tension (rigged/usage) weakens the loops?
may I ask you to test the button knot vs diamond knot on soft shackle? my prediction is that although diamond knot is smaller by size it will behave better and squeeze less on heavy load.
Diamond knot has two strands and button knot has 4 strands in the part that goes through the noose. So the noose has a bigger bend radius and is stronger. That’s why button knot soft shackles are significantly stronger. (IIRC it was on the order of 170 vs 230 percent line strength)
Good eye! We were wondering if anyone would catch that. We caught it during editing and then redid tests and it came out the same so we left it. You really pay attention :)
I have a question about the Button knot soft shackles. Hard to explain but Is it possible that after you go over the button knot with the "hoop" could you then double the hoop over the knot so it might grip the hole thing instead of just hanging over it. Im sure theres a reason not to do this but pretty curious
dyneema is slippery and wouldn't grip. Like if you had a bigger noose and clove hitched the throat below the knot. it is just more bends in the dyneema which might cause it to become weaker.
With the inov split, if the main shackle (the one in fig8) opens up or breaks somehow the whole system fails (i.e no redundancy there)? Since both backups (each side) are connected to that shackle as well? Or did I miss something?
The backups are connected together so the main shackle or main loops can break and you are still connected. One reason why i dont vote for 100m sections cus if that happens, then you drop onto a 200m section instead of my 100m section (2x 50ms joined together)
No. If the primary soft shackle fails then the person would drop onto the back up line. The backup lines are independently connected to one another with a second soft shackle. You can see the configuration at 2:51 .
I just realize I think their might be a major flaw with his test numbers here has the pulley's anchored to the meter I wouldn't be surprised if the shock of the sudden stop spiked the meter. If it being stopped by the safety rope isn't gonna spike it over the brake force then I apologise for this message
We make sure our stopper rope does not interfere with the tests. The shock load from it is not much and never beyond the peak force of the break. We used paracord for the longest time but the knots suck to untie
This was hilarious when I read it. I have highlined with 2 different 16 year olds that (not 16 anymore) that had cool enough parents to let them highline. They went with us and to festivals and were always in good hands. Convince a parent to let you go to a festival like Breathe and you probably could convince them that it is fine. My mom still hates that i do it and look at all the shit i do to make it safe-ish haha.
@@jacksonreich819 good, my favorite festival but im biased ;). Have me meet your parents there and ill tell them in person how safe it is :) How old are you?
Check out our new store! hownot2.store/
As a cruising boat sailor your tests are fascinating. Thanks for your insights.
Our pleasure!

Excellent testing result. Be Safe up there man!
Shouldn't the blue soft shackle should go through both sides of the 8 in the red shackle in tests 530 and 534 ?
Thats what i thought. Will change the topology and how it rolls.

Rule of thumb for (real) dyneema it’s as strong as steel cable of the same diameter. But much lighter.
Another good test to do is put the 5mm inov 8 in the loop, take it to 5Kn, than let it relax, wait some time, do it again to 5Kn, and repeat multiple times. Than break test the loop with inov 8 and see if multiple tension (rigged/usage) weakens the loops?
Jerry has a good machine for cyclic loading. Maybe we can do 100 cycles them break test. My machine isnt good for that.
Why do you say not to use 5mm for the extender, and only use 6mm? Is it because the girth hitch reduces the strength significantly?
thank you ryan!

How many highlines have failed???
Do you do those soft shackles by yourself or buy them? The ones used in your test.
At 15:30, that's not how it's supposed to catch
Good eye! We were wondering if anyone would catch that. We caught it during editing and then redid tests and it came out the same so we left it. You really pay attention :)
i only noticed it after your comment :P
Oh soft shackles have to only be loaded with force one way, but if you tape around the knot
I'd be curious to see this with a thermal camera...

@@HowNOT2 thanx for the reply that makes sence
so basically unless Optimus Prime decides to start highlining, this stuff is rather safe
No, we could make it safe for him too :)

The main line will fail, but there is a second (redundant) soft shackle which connects both ends of the backup, so that will be ok!
No. If the primary soft shackle fails then the person would drop onto the back up line. The backup lines are independently connected to one another with a second soft shackle. You can see the configuration at 2:51 .

"you cannot check it once it is taped" -->any suitable clear tape maybe?
maybe, it could get yellowed in sun quickly
you should make a video to convince a parent that highlining is safer than it sounds and that they should let their child try highlining
