Brass is really shiny at 3:45 when it experience shear forces. as the molecules get crushed against each other and deform, the texture changes and the gold effect it lost. same if you cut it with a saw (same shear force applies)
The wires with red plastic I sent. To the best of my knowledge they are from around 1981 but never used. I have a pile of them so I sent a few to Ryan. I’m very impressed that 40 years made very little difference.
Regarding material strength, steel wire is stable over time (compared to soft materials like Dyneema and nylon). While soft materials will lose strength as they degrade over time, metals only lose strength by experiencing high or repeated stresses. Since you never used them, you were not putting any stress on them (e.g. by repeatedly taking falls), so it's not surprising that they maintained their strength.
You actually set the tricam on active position, passive position is placed like a nut, with the "rolled pin" on the side of the webbing. Acording to NBS it breaks at lower strength when placed in passive position so it woud be interesting to see that! Great video as always!
This was super interesting, I was told years ago that nuts were as strong as their cable and I guess that is true. Thanks for the tricam test, that was really interesting. You guys are doing great work.
Definitely want to see nuts break tests on real rock! Esp. so I can show it to friends who get a little nervous trusting gear when following! Thanks for all y'all do, gang!
My guess on the old hex with the dipped cable is; over time, from use, or even just sitting there, they are exposed to moisture. The coating on the cable made a perfect spot for moisture to get trapped. Even though it's a galvanized cable, any corrosion would have happened there first.
Hi ! I have been gived some olds Hexs from Chouinard Equipement (old name before Black Diamond) by a dude from my alpine club. Of course i have changed every rope and webbing on thoses olds-timers because they are 32 years old mini minimum.. But there is where things gonna interesting ! the holes in the Hex head has been sized for old thicker rope. but i wanted to setup a more thin and lighter rope instead. But because of the size difference the head was mooving too freely, so i have figured to fix that by a creative way, i have cross-twisted the rope inside the head ! It solve my problem but i'm not really aware about how the rope radius is augmtented and how it will affect the solidity.
heck yes, those outdoors in situ tests are really interesting, real rocks, real placements!! Probably going to have to wait for bobby to be 100% again!!
I love going on mountains.. i am not a rock climber i usually do iron way i don't know how you call it .. are mountain way on rocks but with all the stuff already in place and with a stainless cable fixed to the mountain every 5m all along the route from the bottom to the top of the mountain way.. BUT i love this video .. Very Very informative about gears and stuff very related to the climber safety.. because some times i use carabiner or ropes and flat ropes.. So really loved the video ... Hi from Italy
I'd love to see this on real rock! I've whipped on cams but never on a nut. I'd love to see how different style placements affect their hold. Watching your real rock cam tests helped me make better placements!
Hurrah for Campbell nuts; 2:00, nice inner curved arc for sling. Mine slung with 7mm Spectra, triple fisherman's, I suspect might surpass 20kN. Nothing feels as reassuring as a passive wedge in a constriction, set it and forget it. Cams and bolts just don't invoke the sense of absolute security.
breaking at the nut's probably the ideal material efficiency, the cable's cheaper than the machining on those nuts. could just be a difference in design philosophy some companies might just overdesigns the nut then they don't have to worry as much about certification because it'll just do what the cable they stick on it does.
I have a number of Chouinard Hexcentrics from 1972 that were slung with kernmantle rope. Want a couple to bust? It would be interesting to see how 49 years of existence, and lots of climbing affected their breaking strength. I'm in Santa Rosa and could bring them your way.
Unfortunately you’ve been safe the whole time. Lol Also wow that double fisherman tightening! I’ve always been meh that’s enough tail… durp going to add another inch or so just in case I load it with 20KN of force and I some how manage to survive.
This would be a tough one to film but I would love to see a comparison of similar active/passive placements in different types of stone. I climb in the Red River Gorge a lot and wonder if sandstone there - which is a little less solid than other areas - effects the strength of certain pro (especially tri cams). Perhaps something to consider is slowly collecting videos/data of as you travel around.
Would be cool to see nuts placed in their other other orientation (rotated 90 degrees). And then another neat thing would be passive vs. active placement of same size hex?
Love the stress test videos!! Can you do a test on different knots? I am very curious about the strength and possibly of untying the Alpine butterfly bend vs fisherman's bend vs figure 8 bend and maby two bowlines to.. if this video is already made pliz show me! Love the LAB! Peace Norway😄
For gear that is consistently breaking at the carabiner attachment, especially cams, would it make a difference if you increase the bend curvature at that connection point by using 2 carabiners to connect or a large diameter steel shackle? Although not a conventional attachment method it would be interesting to see how strong the wire/slings are with the increased bend curvature or if they start breaking consistently elsewhere.
Since most of these wires are breaking at the carabiner, they might be breaking higher than rated because you are using a round locking carabiner to attach to the wire. Compared to a smaller wire gate carabiner that would normally be used with these, the bend radius of your carabiner is larger, which decreases the stress concentration on the wire, which potentially is what is making the wires break at a higher load than their rating. I'm curious if there would be any difference in performance if you used a carabiner with a smaller bend radius.
Hey Ryan did you ever rerig that cam crusher so it holds cams better? Maybe a couple pieces of gnarly longboard griptape on each inside plate held on with spray epoxy might do the job. Love these tests! Thank you!!!
I'd be really interested to see end-wise placements of hexes, especially hand size or larger. Maybe some more cool collapsing shenanigans? Also would be cool to see off-side placements of nuts.
On the large hex that got crushed maybe BD can put a cylinder of aluminium inside to oppose the crushing force. Shouldn't be difficult to manufacture since the sling/wire will keep it in place.
The red hex breaking like that is probably due to the low friction of your “nut crusher”. The lower the friction the higher the lateral force, and the hex gets squeezed. So this failure mode probably does not translate well to actual usage, since rock has higher friction.
Tip for future: convert the lbs to kgs aswell, it takes no time, adds to quality of the video and i'm sure alot of viewers would appriciate :) Great video!
If possible, I'd love to see tests on marginal placements, rather than bomber lab conditions -- I'm curious what kinds of placements do and don't hold!
Most larger nut designs today induce rotation to include some of those tested - so some are more or less semi passive???? There was some off brand a while back - never saw them in the wild - but was like a two piece wedge nut design - forget what company.... Like two nuts pinned together... Or was it they nested together - can’t remember separately???
I'm entirely unfamiliar with climbing gear, but I am familiar with metallurgy. That looks to me like your "brassy" isn't brass. It could be aluminum, but I suspect it's a steel alloy with a brass layer on top. Allowing the soft bass to slightly deform to increase friction. The silver looks a little too uniform to be friction embedded aluminum.
I'd definitely like to see the nuts tested in real rock, I feel like the point of failure, especially for the smaller nuts, will likely be where the nut wedges against the rock and how the rock holds up to those forces.
In Gegion in Eastern Germany you are not allowed to use Nuts. You have to use Knots. They use them in the same way as you would use a nut but they press them with a peace of wood sometimes. if you want to try this out? i realy want to know about it.
Would you guys be so kind to test your body weight and how many KN put on your body during a fall. I’m sure your subscribers would love a video like that lol

Thanks Ryan and Bobby for all you guys do.
Spot on with the brassie assessment. They are soldered in with silver solder. It is very strong

Somehow I knew the bonus was going to be a tricam, but was very disappointed it wasn't a pink tricam ;)
Soon™. Though it'll be a dyneema one, unless someone else sent nylon-slung versions.
Pink tricam test would be great!
My guess on the old hex with the dipped cable is; over time, from use, or even just sitting there, they are exposed to moisture. The coating on the cable made a perfect spot for moisture to get trapped. Even though it's a galvanized cable, any corrosion would have happened there first.

Would love to see real rock break tests. Was really interesting seeing how the cams preformed in different crack and placement variations.

We americans have stolen your words. We call it Via Ferrata as well. It is becoming more popular in the US.
Definitely need to see a pink tricam tested!!
gunks are all about tricams pink red black!!

Great to see the old school cord slings stand up, I feel so much better about my old gear even though I've retired it.
Yes ! More tricam break tests please ! 😊
Already excited for tricams on Rock (as the bonus of stoppers on rock) 😉😄😄
You are doing a great job. Thanks from Poland

How about trying czech-style knots/textile cams, or pebbles and hardware store nuts, like people used to use?
I second this. this would be extremely interesting. Also simulate a slung tree and chicken head
This!!
I think they did this. Basically the knot shrank and almost always fit through the gap.
Love your tests! Keep going - by a serious fun of yours
Thanks for tricam testing! Can't wait for nuts in rock :) Keep crushing guys!
We will!

Hexes are life. They make placements where the entire rock face would have to fail for it to pull.
Specifically those Wild Country Rockcentrics, soft slings. And if they get too noisy, you can put a layer of Dynamat on the inside lol
Saddle wedges are great in the Gunks. Those channels fit over pebbles and lock those things in.
Really like the faster edits.
Unfortunately you’ve been safe the whole time. Lol
Also wow that double fisherman tightening! I’ve always been meh that’s enough tail… durp going to add another inch or so just in case I load it with 20KN of force and I some how manage to survive.
Of course we want more!
I absolutely love hexes. Started using them from the very first.
and oh yes we will love to see the nuts tested on real rock. And another test on hexes placed in parallel (not tapering) cracks.
I would totally join a live “The force is right” game with a few thousand other people 🤣💪
Snaping cowbell hexes! Radical!
This would be a tough one to film but I would love to see a comparison of similar active/passive placements in different types of stone.

How's the drop tower coming along? Can't wait to see nuts and hexes under some dynamic force!!
Would be cool to see nuts placed in their other other orientation (rotated 90 degrees). And then another neat thing would be passive vs. active placement of same size hex?
As always nice video guys! Keep going!

@@HowNOT2 sweeet looking forward to it 😄 hitting that Bell 👍
Wow! Solid gear.
Please bust more tricams I love them, so far the haven't failed even the .75 is super strong

Although not a conventional attachment method it would be interesting to see how strong the wire/slings are with the increased bend curvature or if they start breaking consistently elsewhere.
Makes you wonder why manufacturers haven't created a solution to this problem by designing a carabiner with a larger radius at the major load points
Since most of these wires are breaking at the carabiner, they might be breaking higher than rated because you are using a round locking carabiner to attach to the wire. Compared to a smaller wire gate carabiner that would normally be used with these, the bend radius of your carabiner is larger, which decreases the stress concentration on the wire, which potentially is what is making the wires break at a higher load than their rating.

Have you tested any ascenders against different thicknesses of ropes?
watching that hex break was so satisfying.
Yes please!!!! *REEL ROCK: BUSTING NUTS* up next
I love this channel!
Have you considered using skateboard grip tape for the cam adapter in order to create friction.
On the large hex that got crushed maybe BD can put a cylinder of aluminium inside to oppose the crushing force. Shouldn't be difficult to manufacture since the sling/wire will keep it in place.
Would love to see tricam and nut placements in real rock! Thanks for doing what you do :)
The red hex breaking like that is probably due to the low friction of your “nut crusher”. The lower the friction the higher the lateral force, and the hex gets squeezed. So this failure mode probably does not translate well to actual usage, since rock has higher friction.
If you guys are looking for audience participation, maybe do some comment contests for the best guess of a break test
The larger hex with the ½" webbing doesnt have a larger bend radius, rather it has two 90° radii
Still have a set of those BD nuts so glad to know I may not die on them since I weigh a kn
Can you test different types of slings basket hitched or girth hitched thru the nut's cable loop? Also more tricams=yes
Tip for future: convert the lbs to kgs aswell, it takes no time, adds to quality of the video and i'm sure alot of viewers would appriciate :) Great video!
Thanks!
We are measuring force not mass. KN (Metric) and lbf are both used to measure force whereas kg and lbs are used to measure mass.
@@HowNOT2 But wouldn't it work to convert lbf to kgf? Feels like i don't know what i'm talking about, sorry if it's completely wrong! :D
That smashed hex is awesome!
Overall these are some pretty good engineering designs for this rock climbing stuff
More tricams please!
Would be interesting to see how tough different rock materials are with the wedges 🤔
You should break test the Finsterwolder Quick outs
Yes!! TRI cams
tri-lambs ! tri-lambs ! tri-lambs .... er.. tri- cams ! tri-cams !
Interested to see DMM and Black Diamond micronuts tested.
We tested them in real rock. Video coming in the next few weeks. Stay tuned!
Tricams! Tricams! Tricams!
I’ve got dyneema slung tri cams I think they are rated around 17kn or so.
we want to see tricams in different positions and see how they behave. Very tricky to test that with real people
If possible, I'd love to see tests on marginal placements, rather than bomber lab conditions -- I'm curious what kinds of placements do and don't hold!
I’d be interested in testing small brassies with different diameter carabiners.. are super small biners making pro weaker?
My group does not love the nut life. Bunch'a CAM lovers! Passive sends are the best sends.
Tricams tricams tricams! The best of both worlds!
Unfortunately I may fall into the cam lover camp :P

If pro breaks at the carabiner, how significant of a factor is the choice of carabiner? some have much smaller radii.
