This video would be better with more sailing/story from your guest. Get me invested in the testing what are these things doing? How did highlining steal them from sailing. Does my poor homeboy's sail fall off with out em? I want to cheer for that dyneema! P.S. Love the new direction Ryan, I hope you crush it literally!
@@joestevenson5568 A rope is coiled and has no working job, a line has a working function and a sheet is a line used to trim sails 😉Somewhere in the millennia of application distinctions were made in sailing and those distinctions are still used today. Also, there is a very good chance you will be immediately corrected as every line has a conveniently specific name directly related to the job it does. Volunteer to crew if you have the chance, the logic of this will become very apparent.
This was great! Thanks for going down the rabbit hole and testing everything that came up. The bad button knot was an eyeopener for me, though! What a giant loss of performance. 😅
One problem with button knot when sailing, is where your line diameter is restricted by the size of the attachment. With buttons and their thicker noose you have to downsize line dimeter quicker, loosing any gains in strength. You can also make shorter shackles with the diamond knot, which is import if something needs to be attached close for performance reasons.
Very interesting. We are also into sailing :-) We are re-rigging our 44 year old 38 foot boat with all dyneema. Including the chainplates. We are using the overhand knot style of soft shackle from your channel (because the bigger know is a positive advantage for us). Instead of the eye looping over the knot we keep the full length. The knot is inside the boat under a big backing plate. The eye goes through a small hole to above the deck. We are putting a low friction ring in the eye and then the dyneema shroud that holds up the mast is lashed to this. Will start with some load testing in the next few weeks. Of course our scale is a bit larger. For our mizzen mast (the shorter mast) we are using 9mm dyneema (way over strength but that is because we are sizing for stretch to be similar to 6mm stainless steel).
In my experience playing around with both of these knots, I've found that the button knot is harder to tie in smaller diameter lines. It seems like it's easier to make a tangled mess in narrower lines while the diamond knot is relatively easy to tie. For light duty applications, a diamond knot in smaller diameter line might be the right combination of ease of tying and "super good enough."
Awesome!! I don't high line or sail but I I do hang my hammock and things with dyneema 7/64 and that stuff is way stronger than I would ever need. Thanks for the video. This is great content!!
Very good guys. Love the sailing stuff. I’m a sailor and have been following since all the stuff is relevant. After all, occasionally I need to climb the mast.
Love me a soft shackle face off......considering the challenges you both had with the complexity of the two knots reckon you could try using a spliced continuous loop with loop locked overhand knot (this is where an overhand knot with the tail passing through as the terminating tail ‘ear loop’ is then locked off by passing the soft shackle loop through the ‘ear loop’ at the knot to then lock the overhand knot off....the knot is tied into the splice) Much easier to tie (not so easy to describe)....really just an overhand knot and a splice....with the advantages of the button knot. Love your work
You mean this one ;) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jU_mmdbQeCQ.html. It has a huge head and that is why I don't use it. we also have 2 or 3 other designs people have sent me that look neat too. Gunna test em all
@@HowNOT2 Thanks for the reply, yep that one (just using a continuous loop not eye spliced ends), yep the knot is pretty big....but pretty fool proof to tie. Looking forward to more testing, more learning, cheers.
Nice! Now please test the Ashley Stopper Knot (no. 526) also... 🙂 I see it''s commonly used among sailors and hammockers in soft shackles. But I can't find any tests whatsoever, and I'm a bit worried the knot maybe just slip before anything breaks.
If you don't properly set the diamond knot it is just like anything when you don't make something correctly and then it fails. WTF do you expect? When you properly set a diamond knot you can tap it on a table and it should sound like it is made of metal or wood rather than feathers. I invented the idea of making soft shackles stronger by bringing the line back down through the knot and tucking them inside the line. Brion Toss came up with the actual button knot. A third person with screen name Estar did the testing and had the initial requirement for a stronger soft shackle which was to be able to pass the shackle through anchor chain. In the end, both Estar and I preferred the diamond knot and Brion preferred the button knot. What Estar and I preferred is using thicker Amsteel if you want a stronger soft shackle. Here is the dollars of it. For about +70% in price of thicker Amsteel, you get +60% more strength. For a button knot, for +14% more line (the tucks) you get 35% more strength. From that standpoint the button knot is a better deal but not by a lot. But the downside is it is harder to tie and is smaller so right there seems less secure, and you are stuck with the two strand Kohlhoff style with the open body rather than what is more secure in either the Colloigomarine style or my style what I call a better soft shackle and Animated Knots calls the Edwards soft shackle (my name). Much more on my website under Soft Shackle tab. Allen L-36.com PS. I love your videos. I wish I had that test gear. Ester had a hydraulic press on an I beam. I use a winch on a 4x4 but can only break lashit. I hope you read this comment.
There's a version of this soft shackle with a bury. I wonder if it will perform differently. Note that what he calls a diamond knot is what you call a button knot.
I think the mix in breaking amounts would be due to not dressing/ setting. Would love to see the button not vs a diamond with a small 1/4” stub with both tails whipped together with locking whipping. I have a feeling forcing both ends to slip at the same time could I crease the breaking load dramatically. Not as much as setting the not correctly though.
Next time you’re messing with this sort of stuff I’d like to hear about button knots with one or 2 inch tails that are not buried. Burying the tails is kind of a pain if it’s not necessary.
Really wanting to see Ryan trying out the other sports in these collaborations. All the expertise these people have and not taking part in their discipline is leaving so much on the table. After all, there’s precedent: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-exqHGwFhw7o.html - an epic ‘Sketchy’ tandem base jump from GGBY. (One of the greatest How Not 2s ever!)
I will be trying the other sports out, but this isn't a channel vlogging me having fun, but to break gear fear. I will be dabbling in all of them but it takes time and the drop tower is my focus right now.
@@HowNOT2 Point taken, the drop tower is a vast undertaking (literally) and will bring so much by way of new abilities to you lab. However, you work with an great commitment not found too frequently on RU-vid, if I may suggest, when the time is right, there’s plenty of us - I’m certain - who would support you going to having some ‘fun’. For example , putting a Linescale on certain high pressure, often life critical, systems like spinnaker sheets on a boat would make for an excellent short series. Just a thought for the future.
A few things I noticed: 1. The 3mm diamond vs 1/8 button and dyneema vs amsteel was not an apples to apples comparison - it would have been nice to see a single line breaking strain on the 1/8 amsteel. 2. The knots (usually) didn’t fail - doesn’t this imply that the extra strength attributed to the button knot was solely due to the larger diameter that the eye is wrapping around? 3. You seem to have done an apples to apples comparison with the 2mm but you kind of rushed through that bit. Awesome video and really appreciate the analysis
I will watch this vid. I'm a cool homeless person. I take anyone into the wilderness. I'm Ben Rockwell. I'm really hoping I'm driving some donations your way. Speak it and it will be true. I'm sending my "guiding" money to you.
I thought you'd be interested in this vid (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o4J4hJoJFHg.html) where he uses locking brumel splices so the ends are completely buried to stop the ends pulling through the knot. I wonder how that effects the strength?
