Enjoyed the video and learned the "40% strength retained" rule of thumb for Dyneema--useful info. But come on, kN? Seems apt if you're measuring, I dunno, asteroid impact effects on Jupiter, but bro inches and pounds for Earthlings, please.

Why must I continuously have to subscribe to your Channel about every 2 days I'm unsubscribed long time follower of the channel love your work great solid info keep it up guys. I do believe some of the stuff you're testing is being paid to Shadow ban and throttle back your viewing to keep your ratings low so your information doesn't get out about their product true facts science

Have you ever done a video on blocking knots through an anchor? I was rappelling and using a figure 8 as a block knot on a 7mm quick link. Rope diameter was 8.5mm. I was just messing around in the back yard but was wondering how much force it would take to get a block knot through an anchor

Thanks a ton!

Sweet and simple, love it, thanks for the videos !

legend, just got our one today and looking forward to putting it to use! thanks for the run down

Wait I'm confused, you aren't supposed to tie knots with it? How is a rope useful without tieing knots in it? Every time you use it you have to splice it? I bet it just won't get used much then

Classic Pete ranting!!

Is it safe to leave knots permanently tied in on dyneema? Like for an anchor. I leave knots in mine, never bother untying it, but I worry that constant loads on the same knot will cause issues in the long run even though I have no evidence to support that fear

in hammock uktralight setups, you wouldn't use metal carabineers. How do dyneema soft shackles behave when they are chained? They are sharp angled to each other. I think it will be very weak spot

This knot is fantastic - easiest to undo of all the knots I've used for blocks. Thanks for posting it in short form.

Just for those that are wondering, Dyneema is a brand name. The name of the material Dyneema is made out of is UHMWPE. Spectra is also a brand name made out of the same material.

If webbing always breaks in the knot, why don't we use a buckle? Like on an harness.

Looking for information on spectra twine

You hitched it backwards from the way I do it. I set the downline and fiddle stick leash on the same side because the rope looping below the fiddle stick slopes to the downline side and makes retrieving the fiddle stick easier.

Thank you for this! As an arborist i do this a lot, with a beefy steel triple locking biner

So you should treat your ropes with flooded basement water

Ryan, have you ever done testing of via ferrata sets? I weight about what the upper limit of most ferrata sets is (~120kg) and you be interested to see at which force set as a whole will break...

I thought dyneema can’t handle heat from the friction of a rappel?

Have you tested a soft shackle like the one in this video ruclips.net/video/QYZ3ZL1Mhao/видео.htmlsi=1oiPmQt6MEk6Y9Of ?

I've watched a heap of your videos and learned a lot. Thanks very much! Your alpine quickdraws always catch my attention. What's with the twists?

Super Aids?!

What about the knot on the end of a soft shackle? Or Ester knots? All knots on dyneema.

I have seen instructions in this lean to Rings vice carabiners for canopy anchors.

Perhaps it’s an odd question but, if the sling is damaged and you want to isolate it would it be a “better” solution to cut the damage area and then tie a water knot with the sling instead of using an overhand? Maybe it wouldn’t matter but I’m curious. 🧐

Interessantíssimo, principalmente o primeiro soft shackle cujo nó se desfez mas o loop permaneceu intacto levando em consideração que a única coisa que o segurava é o burried end dentro da própria corda. Obrigado pelo vídeo.

Hello, good day, great job. I have a questions: ¿what is the fall factor and resulting impact force if the anchor where the main carabiner is attached were to fail? Let's consider a person weighing 70 kg with a lanyard of 70 cm, keeping in mind that these chains, on average, have 30 cm of separation between each of their anchors? 6kN ? Wouldn't it be more advisable to use the lower anchor?

try it with 2 green

This looks a lot like a marlinspike hitch. Would using a marlinspike or similar, of course with a backup line, be appropriate? I'd rather carry a multi-purpose spike, even if it weighs a tad more, than a more limited piece of plastic.

I'm impressed that the knots broke and didnt just slip.

Use this all the time, works great

Dude you’re a male, your acting funny like a female. Gay much?

So, basically 40% strenght rdtained.

FYI for the date format, using year-month-day format can be nice for ordering stuff on a computer. I somewhat commonly use that date format as a software developer. I'm guessing the date ends up in the log file names right? So if you have several logs on different days (especially if those days are in different months or years) then if you sort by the file name, year-month-day will always sort chronologically. This doesn't really matter if the device has some different method of sorting log files. E.g. if the file names begin with a number that just increments by one for each new log, then sorting on file name would always sort things chronologically anyway.

Wow, thanks again. I watched this carefully, and realized I normally want continuous log mode for my tests. I also realized how easy it is to pick the wrong choice.... boy those 1280 Hz logs fill up space quickly... Thanks, thanks, thanks.

On Android, app says it is saving the log, but it does not appear anywhere on device. Andy knows this, but does not have a programmer to fix.

I was pleased to see that a figure 8, knot will break rather than slip. I always thought that every knot in dyneema would simply untie itself by slipping rather than break.

"I WANT ONE"

Please comment your tips and tricks to make this section super helpful. Thanks!

Not a ‘fast to release’ system configuration and the station must be a stable area that the operator can comfortably be positioned directly next to the block.

Hey guys, Would you PLEASE do a video break-testing draws that have been left on the wall for a season or two? I've heard way too many stories of people falling on old project draws and they break so easily, sometimes multiple in a row. It is a huge danger in Sinks Canyon, Wyoming where everyone leaves their gear on for years and years and people just blindly trust it. We need a PSA from the pros! It would be neat if you did some on the bench test and others maybe in a climbing gym to see if they actually blow or not (high up enough obviously where it's safe to fall further). Also maybe some old slings left on the wall as extensions! I see this a lot too and they are so dangerously worn. Coming from an operating room nurse, I just want everyone to be as safe as possible when crushing projects :)

Man I almost cried watching that 30 year old REI draw get busted. What a cool piece of history. I would make some neat wall art with those if I had some.

If you decide to do a more exhaustive test use Triple Action, Double Locking carabiners like the ones that arborists use. I suspect it will make no difference in terms of breaking strength, but it would produce test results that are directly applicable to the kinds of carabiners that are required for tree climbers in Federal agencies like the US Forest Service and Bureau of Land Management.

Do you use a third hand in canyoneering?

I don’t think this is quite as redundant as it looks, if one loop were cut, then the other becomes very sketchy very quickly.

There is no reason for the stone knot and carabiner.

Why aren't the stitches diagonal to the direction of pull? I think diagonal stitching will give lower highs and higher lows of force

I use maillons (quick link) for putting ropes to trees. Being shorter than carabiner, there is less to be bent. They take side loading better too (and are less likely to get side loaded) which I find good for something that is difficult/impossible to inspect up there. Smaller pipe would be interesting to see, especially if agains maillons too.

Pointless to use with double strand.

👏👏👏
