Metolius TCU climbing cams pulled until failure - Great Slow Motion!

would you like to see us pull this came out of this crack with that pulley system we're going to pull some cams straight in line out of this crack on this episode of cam crusher hi I'm Ryan jinx and welcome to how not High Line go to slackline calm it's our new domain for our website that we just updated it's got lots of good stuff on there today we are going to pull out some cams straight in line or out of line out of this crack that we have here in the middle of nowhere in our previous episode we pulled in this crack we pulled that direction and we were testing to see if the wires the stems of the cams going over a sharp edge reduce the strength and we've got very interesting results most the time it didn't actually reduce the strength having this Tim Gover a sharp edge like this but it did mess up the cam so as far as safety goes it was super good enough but we're gonna find out how strong these cams are and if they slip now in select snap here at my garage we actually have the cams slipping out of our adapter that we made for slack snap and that's because it's you know two pieces of metal and metals just sliding on metal we are gonna see if we can get some rocks to fit in this slack snap machine got some ideas for that but we're out here in the middle of nowhere in order to see if the cams will slip with real granite this is this is the Sierras in California so this is a pretty good granite there are some there's some decomposed stuff out here but not much anyways let me show you what we've got for our test system that we've mocked up here this is a red TCU metolius that is about 15 years old this is my personal cam that we're testing here they were great when I had them and they were great for what I was doing with piton scars in Yosemite but if you're a cam connoisseur mmm you can judge my placement here just so you can totally see what we're working with before we try to pull it out so we have the cam a 72 kilonewton carabiner going to our dynamometer that we use in slack snap now we just broke a lime scale so we're a little afraid to use our second one we only have two and if you guys buy line scales from Len grip comm I won't have any to buy he is running low but he is ordering more anyways it is the preferred one to use in this case so what we have here is a SMC poly these are 45 kilonewtons here which is probably where they'd break and so we can use them on tests that are less than 45 kilograms Gregory and the brake we've got our multiplier here actually it's 27 to one because he's multiplied it again first of all don't judge me if I'm wrong second of all I don't use pulleys cuz I'm a high liner and we just do a three to one on everything what is this leave this in the comments below because it's good for the algorithm so this is a nine to one when you multiply the four or five to one man you think I would know this I'm the how not to High Line guy and then you add a multiplier to that so that's a three to one on the three to one so it's nine times whatever the heck you want to consider that nine times five strands four strands leave that in comments below we're actually interested in cams in this test let's get to it whoa so those lobes are almost fully open and the rock cracked it's just grabbing that now we're gonna keep pulling this if it slips out we can always put it back in but that is that's interesting it slipped we didn't get any slippage when we were pulling it not in line at 5.5 it slipped well let's just keep pulling that's what we're testing three four three four four point eight kilonewtons in order to get it to come out and it looks like this I guess this rock isn't as good as we thought we can put it in deeper and try it again condition of it is well it's it's a well-used cam so I don't know how much teeth damage is from today I definitely think this right here is from that test you can see that the teeth here are how they're supposed to look you can see what grinded teeth look like all right so let's stick this thing back in and see what happens we're at 7.9 kilonewtons whoa it's just moving yeah still well-placed you're at ten point three level five need some help need some help Oliver holy crap we need to do better with our catchers man oh man oh man that just she's a slippery girl look at that we got some skid marks oh we just keep breaking things we're not trying to break how's the dyno works whoa okay so yeah that looks like that old guy in Aladdin at the beginning looks like his teeth it's eleven eleven twenty five I mean pretty hard to generate that in a whipper okay so we just looked at the slow-mo videos cuz we like doing that after every test cos they're fun to watch and I noticed there was like a jolt and I thought the camera moved but I realized this rock was moving what okay so whatever the rock moves but I would totally use this situation if I was really climbing or springing a Highline I guess because this looks plenty big it's not super well seated underneath here but this is a PFR a big freaking rock the rock moved apart we're gonna have to test this may be in a different crack that's bigger rocks maybe stuff behind us we'll test this one more time I put it in a mark of a constrictor so the rock would really have to move in order to have this come out technically the cam did not slip the rock failed or moved that's interesting that's a lot of force being put on the outside force if you know cam math tell us how much our 11.8 5 kilonewtons this way put on the rock this way I'll be sure to read all the comments after you show us the math on that another thing that we're going to do to keep this stuff from flying is we have placed really low here a removable Titan something that's easy on screws what we use for most of our bolt Buster tests and so that way this is not going to break or come out just like our orange tea see you did when we quickly placed it in there it was supposed to catch this thing and I went flying so anyways let's zero this out and Bobby let's start start pulling on this [Music] that is funny it's still kind of the teeth aren't the the lobes are still at an angle this thing is getting pretty trashed at 10.1 I think our rock is not good enough anymore super not good enough for it to come out like that is nuts you can see the marks here and here you gotta find something a little bit more sturdy rocks strong enough I'm an expert climber first crack when you need it Oh yellow will fit rattle fit and I'll make the orange bit let's do this crack it takes quite a bit to set up each one of these tests but we are finally ready let me show you what we got we put in a the bolt from over there we just move it around and then this is long enough but not so long that this won't hit the ground but we don't you know trust our judgment anymore so we are and our placements all right we can get a yellow red and an orange in here and this is kind of a flaring crack but it was a good placement it's totally something I would normally use right now we have two kilonewtons on it you can see on this side it's kind of scary filming this that it's kind of a wider on that one lobe than on these lobes but yeah this is also really damaged cam that we've already pulled tested a bunch I don't think this rocks gonna move because it would literally have to lift up that giant thing in order to get this to go so let's see if we figured out how to break some cams so these lobes are kind of open right here it's probably around 8 kilonewtons Bobby's gonna add some mechanical advantage well it's pretty good considering they're not all even [Music] our system worked that's a quarter inch bulb okay interesting fifteen point eight five kilonewtons well we had both had to pull with the double mechanical advantage to get that to work so that's usually what breaks so the cables usually break next this plastic is just that's just plastic that's broken but the cables are fine when we put a carabiner on this the bend radius is smaller than what the sling is is so that's usually why it breaks right there but it didn't come out man these rocks are not budging so it's a good spot and these lobes are they're not perfect but they're doing their job that was after we had already taken it up to ten eleven oh yeah yeah we've already break tested this four times now before we put this back in look at how I kind of chewed up that is and this cam used to be more curvy so we're gonna it's still kind of works we're gonna put it back in there and and just do what we can we're trying to break this wire right here because that's usually what is the next thing to go well Bobby's setting us up we'll take a moment for our sponsors we are sponsored by no one I started a coffee business with my friend and we make instant coffee you basically pour it in hot water that's how instant coffee works but we made it with a specialty espresso fancy-ass coffee so it tastes really really good do you want to help support this channel you can donate on paypal patreon or by some of our coffee it really really helps I put two hundred percent of your donations back in this channel now let's see if this chewed up red teeth you has any life left hand Vettel's crunching those lobes are like one with the rock I mean it's 100% touching because it blacks into the house no I wonder if we'll ever get that thing out of there that is amazing that held ow Dow that's sharp so I just grabbed that with my hand in order to pull the trigger oh my gosh it comes out quite well actually so is that granite stuck to it or is that just no teeth left I think this Tam is done what do you think whoa consistency is that consistent fourteen point seven it's less so we do get higher strength on the slings than we get when we pull on the stuff holding the slings but that's because of the Bend radius carabiners fine so let's test the orange TCU which is the next size down from this one and see if we get consistent fish results [Music] the cameras over hey that's not the top that's the side interesting alright pull the trigger see if we I can salvage Old Betsy Hey good as new and it came out so you can see the skid marks right there yeah I don't know if I can see any up there let's see if we can place it in better and get a better result dan what is our result well ten point one's not bad does even get more oh the sling broke shocker this just shows Bobby's better at placing Kansas Oh Bobby thinks he's better at placing cans I was trying not to place it perfect we're gonna break the next test without touching that 12.4 in order to break the sling cool eh the wires broke what are the chances right where the carabiner connects how does it happen no bulbs are looking good that ant is in a sketchy spot to be walking can you imagine being an ant and having a cam boy your head off 14.4 wait [Music] ten point seven five I'm seeing a pattern yeah here maybe if Bobby places it'll do better oh nice or cammed hey mr. Fixit oh that this last load here is is oh gosh freewheelin freewheeling this thing is I need some braces alright let's no do what we do [Music] it came out Bobby I thought you're good at placing this stuff what's happening I imagine is these two outer stems are bending the center rod I can't imagine it being anything else making these lobes and do that okay so let's see if we can fix it again we'll try to stick it in one more time and do one last test with it we did pretty consistent yeah so now you know how much it takes to pull out Bobby's good at placing cams 14.3 as nard as that cam was I mean that's impressive so the sling finally broke I don't know if this is a mixed blend or all Dyneema but it's definitely not a hundred percent nylon definitely not pulling that out well it was well let's see if the wire breaks first probably will [Music] whoa something different right there Bryce not what's broke this one of the stems that's cool look it just sheared it off clean look how many Newtons it is Wow that's science guys count your blessings that we got the dyno right all the other tests but because we fold enough things I bet you that was in the 14 kilonewton range we could be off by up to two kilonewtons but definitely not more than that because we're experts at pulling without falling over Bobby did fall over the first time on the first sample Bobby fell twice yeah so I don't think I'm gonna be using this anymore go to slackline calm if you want to learn highlining A to Z we've got highlining 101 out it's 80 videos and a textbook all dad got the bolting Bible and if you want to see these break tests all the charts of the data and the videos the raw videos it's all on the website slackline calm it's all available and there's all free this is all based donation based I make very little off of ads that I make you watch at the beginning of this video hey we got science how Oh fifteen point two five four that we were within a kilonewton tried of guessing we were pulling pretty hard fifteen point one two five cool well let us know what you want to see we're gonna stop breaking camps at this point we have another cam episode that we pulled out of unfavourably yep this one and we did some in our cam crusher slack snap break test machine at home already but it kept sliding out because that's metal and we just know that you guys wanted to see it in real rock so put in the comments below what you want to see next we've got more cams coming that people are donating if you want to donate some gear please hit me up on facebook messenger ryan jinx dot 35 is the my facebook please send it to my personal one not my how not to i line one and we definitely read all the comments so we know what to do next and how to do it better we're always getting better at this stuff so yeah definitely leave vague comments about how we're destroying people's lives or hurting people's knowledge we love helpful trolls it's good for the algorithm so you can troll me that's fine why shouldn't we Highline cams we need a good pullout joke sometimes pulling out is safer therefore you shouldn't climb sorry it's the best I could do [Music] [Music] [Music] [Music] [Music] you
