Thanks for this.. Not because I’ll ever repair a trampoline, but because it’s a video about spending a lot of time fixing a thing that is easy to replace. You could make the same video about putting a new drawer slide in an Ikea cabinet. Things can be fixed, and giving it a try is low risk if your intention was to replace it anyway.
I see trampolines being given away on Craigslist on a weekly basis, not to mention lawnmowers and yard tractors that only need minor repairs. People just want shiny new things.
@@mikem3695 oh, we've been in that lala-land for only a few years, I think from 98-ish until 2009 and then we already got super tight. It's been squeezing harder and harder since. Not that people here have learned to give repair a try, but it's come to the point where the European legislation now has a bill in effect about "the right to repair", forcing manufacturers to change their product designs in order to facilitate repair, or in some cases to prevent premature wear and tear like with most electronics nowadays... (many still include software EOL-timers (end of life) that systematically shuts down functions after a certain amount of use-time, typically 2 years. It's not a coincidence. It is by design. And I know this from seeing the policies with my own eyes, which is probably the biggest reason why I left electronics design.) Anyway, I'd love to see someone give a way a yard tractor, even if it was run over by a fire truck... We don't get so lucky to get things for free here. The only thing you get for free, is crap for being overdue with the bills.
One thing I've learned in my many years of repairing clothes is that uniformity matters, especially in applications where there will be a lot of tension. Small straight stitches tend to do the best. I suspect those huge stitches from the factory are one of many cost saving measures. Great video, not enough people try to get the most out of their stuff.
You are totally right. My experience has told me the same. Small, straight stitches are super-tough, especially when you isolate them into groups by throwing in some knots. In fact, the replacement stitching here was already much, much stronger than any of the factory stitches, so a DIY repair could be downright messy and still work!
I like your approach to trying to squeeze the most life out of things we use. This made me want to check our trampoline and I was surprised to see it was built with a line running around through each d-ring. The problem with ours is springs snapping at the hooks.
People severely underestimate sewing as a handyman's tool. Upholstery string and some heavy-duty needles can do some awesome things. Tho I'm going to at that fishing line to my sewing kit. Oh, and nothing wrong with pliers, I do the exact same thing, but don't underestimate a good thimble. There's so much ancient technology we're sleeping on because we're so used to thinking of it is outdated. Figuring out what the little coins with the wire hanging out of it were was life-changing. Side note, I always wanted a "power tool" battery operated sewing machine in the same style of DeWalt or Ryobi. Something with some grit and power behind it. I know for Tradesmen if a tarp rips or if a bag needs repairs it's much easier to just toss it aside and get something else. Time is money. So it wouldn't be the for the back of a pickup truck. But I still feel like a heavy duty portable sewing machine would be useful for around the house handyman crafting stuff. Especially for convention costume repair. I think cosplayers would eat a power tool sewing machine up like candy.
Perfect timing! I have my trampoline dismantled for some winter maintenance as we speak. In my case two of the little loops that hold the triangles have worn through so I'll need to find something stronger. Good tip on the braided fishing line - I had no idea what to use so I went with waxed braided nylon from a leather supplier.
I found you by searching Google to ask if flex seal would work to patch a trampoline. I have a tiny spot that is starting to wear a bit and want to catch it before it really turns into a hole. I think this a great fix if it's something someone has on hand. Price wise though, I don't know if it is much more/less than an actual patch. Anyways, thank you so much for sharing this ❤
First thing I thought after you showed how the spring was ejected and how the stitching broke was "wait, why didn't they attached the springs to the outer metal ring ???" I have never had a trampoline nor did I have the occasion to look at one from close, but the overlap between the trampoline's mate and the straps that holds the triangles look to me a little bit low, may be it's "normal", I don't know. Also when you talked about your safety solution and started to implement it, I was like "wait, how do you know that this is going to actually work ?" and then when I saw the ratchet binder I was so happy to see that you actually tested your solution to the problem :D For the 8 figure knot, I thought that you were going to follow the first 8 figure with the other end of the rope, not with the same end. So you would end up with one knot and not two. Does that make a difference (apart from having a harder time tightening the rope when you have only one knot) ? Also if someone uses the rope solution, you need to tighten the rope at least a little bit, because I think there might be a scenario where having a non tightened rope can allow the spring to still gain some momentum and then be able to escape the triangle with speed.
The paracord loop only needs to be snug, because _it_ acts as an inertia absorber when it grabs a launched spring. Some give here is good; think of it as being like a fireman's net (a life net). If an object in motion is stopped too quickly, often the 'equal and opposite' reaction instead becomes manifest as an equal and opposite motion. We don't want that. Elastic collisions are great for billiards, but not so good for catching falling people or projectile springs. If the loop were metal instead of cord, it might allow a spring to preserve and thus redirect its motion toward the person who's bouncing. The figure eight: tying two knots to one triangle was as simple as I could make it. Not only is the knot mass reduced, but the knots will be less likely to come undone than a rope-to-rope circuit knot, and it's also easier to visually inspect. Oh, and it's easier to describe on camera. Nylon strap's tiny surface-area contact with mat: normally, the amount of tensile force placed upon an individual spring is kinda small. I don't need to explain to you the mathematical dissipation of a 300-lb force over 96 parts, but let me say that our natural intuitive sense will tend to overestimate just how much work a trampoline spring is usually doing. ----- How did I know that the solution would work before actually testing it? Okay, this point is your most interesting bit of skepticism. I appreciate it, and I want you to really listen to me here. You've probably heard me preach before that there are two types of knowledge, _a priori_ and _a posteriori._ This is just the difference between the imagined and the observed. We scientific-types tend to scoff at the former. We want evidence. When I was young, I was strictly empirical, rigorous. Imagining an experiment can't be as trustworthy as running the actual experiment, right? But now I understand _how to imagine_ much, much better. Let me explain. My gamble here was with potential lost time, and I could've also been filming a useless video. This is, except that I was extremely thorough with my _a priori_ reasoning. One can learn to run experiments in one's head well enough to prove, mathematically, or logically, within a reasonable expectation of error, many of the world's basic physics problems. Point is, as you gain skill as a practitioner of empiricism, don't lose sight of the incredible real-world utility of reason. Though there can be no certainty in forethought, I was _certain enough_ to wager my time and video, knowing that it was a safe bet. Try it. Imagine the spring's motion in your head. Replay it in slow motion, and try to account for everything that is likely to happen during the event. One can get better and better at doing this with practice. Just remember error. Account for your personal biases. And be mindful of your own arrogance. Remember how during the second trial the spring caught the other triangle? Though it wasn't quite relative to the outcome, I still didn't see that coming.
@@pocket83squared Hi, thanks for taking the time to answer :) I love that flow from priori to posteriori. Even in empiricism we can't escape priori knowledge : what experiment should I run ? I'm still young, but I out grew my extreme skeptic phase. I'm still skeptic, but more like practical skeptic. Sometimes (well almost always) you can't test everything nor can you head to the right direction right away, and that gave me so much frustration in the past, because everything felt like moving mountains while being a tiny little dust. I always wanted to get things done correctly (perfectly ?) from the first try. Sometimes this behavior annoys me so much that I go to the opposite side and improvise too much to the point where I'm even more frustrated from the lack of control and so I don't learn anything because I didn't evaluate my priori to compare it to the results. Now that I have a job, being an extreme skeptic is just unthinkable of (well I still allow myself sometimes to be a moderate skeptic, I either lose time or I gain something precious). We lack so much time that we "just do the thing, if it works great, if not now you know that it doesn't" (we don't build nuclear power plants so no worries !), as you said, we are constantly betting. We don't have the time to apply the theory, we rather apply the practice to the theory, by updating our knowledge as we succeed or fail. This way of doing things is so much opposed to the way I always used to think that it can be frustrating for me and I have to force myself to do it that way because it's what works best. I'm still very thankful for my job, I have never been able to learn that much before. I was always struggling with theory and always thought that it was right way to do and learn things. Of course I'm not saying by any mean that theory is useless or some other thing. I hope what I wrote makes sense and is related to your reply (if it doesn't, in my defense I was too tired when I wrote this hehe) Again, thanks for your insights, it makes me think and wonder :)
The cable in garage door springs is to capture the fragments if the spring breaks? That's truly a new bit of knowledge I gained today :) (scouts honour, not being sarcastic, even though it really looks like it... Deng it, now it looks like it even more... But it isn't. I swear.) I always thought they were a dead stop to prevent the door to ride off the rails in case the spring gave, or if the spring stretches on the way down, so that the door would slam shut and possibly crack, but not leave the facade, frame and all... I would think the most dangerous fragments of a spring breaking from fatigue, would be the tiny fragments that shoot out to the side, perpendicular to the pulling axis... (I remember those from the metal rods we pulled to the point of destruction in the tensile strength lab tests back in my college days) Oh well, what do I know... Watching this video I got brutally interrupted by the dying screams of a young woman. As I ran out, I found a woman curled up in my neighbors enclosed front yard in the corner against the fence between our properties, panting and screaming... She stated that her dad was chasing her with a shot gun... Called the cops. As they got out, the first cop that approached her (a lady cop) said: "But... Julie, we just dropped you off at your dad's house this morning..." (meaning that she had already spent last night in their custody for something) She had also claimed that the guy with the rifle/shotgun had entered my neighbor's house. A quick call to him fixed that issue. The man was playing Fortnight and hadn't heard her climbing his fence while screaming at the top of her lungs... Yep, I'm guessing XtlMeth has found its way to the mainland... (i.e. Europe.) Never had an encounter with someone on a meth high, so I didn't recognize it at first and took all of her claims seriously. Until she claimed that her father owned all our houses and that the cops were corrupt and in league with everybody in our street... Then I knew she was either an escapee from a mental institution or a drugged up user or something... Cops took her with them when their backup arrived. So they know her, _and_ they know to bring 4 officers when they have to drop her off at home. I think that says something... Now I have the terrible task of coming down this adrenaline high hahaha. I guess I'll have to rewatch some more pocket content. (not that it makes me sleepy, because they usually make me think more. But he's got one of the most calming voices of YT vloggers in my subscriptionlist)
We once had a visitor here who was on crystal meth. He stopped in at 3 AM on a July Saturday wearing no clothes except for a loose beach towel. He didn't knock, but I'd heard him cough from the front porch since the windows were open. The guy was kinda tough-looking, a little scummy, and probably 10-15 years younger than me. Naturally, I decided to stay inside and try to calm him down through the window; I didn't tell him that there was a pistol being pointed at him. I wasn't as soothing as you might think; I was being pretty stern, almost forceful, probably too much, but he seemed to respond better to demands. Note that I'm in full adrenaline rush and trying to avoid a fight. After I'd talked him into sitting down on the patio, I gave him a bottled water as an olive branch, and got him to become almost sane, that is, until he went into a frenzy when an owl hoo-HOO-hooted, screaming that the sound was coming from "them!" (even though he knew I wouldn't believe it). The poor guy was terrified. He eventually admitted to smoking meth, and he just wanted a ride home since he was out here in the middle of nowhere walking barefoot through the dark. My wife had already quietly called the cops, and so I told the guy that he had two options: either he could stay here and wait for them to give him a ride, or I could give him a ride now in the back of my pickup truck. He was insulted, but I insisted to him that there was NO WAY a naked stranger was getting in my truck while high on meth. He reluctantly agreed, but then bitched the whole way home (about three miles). Before the truck even stopped, he jumped out of the bed as we got near his house. He then ran into the bushes around his neighbor's house, apparently to resume hiding. The cops became uninterested in this story after I decided to 'take the law into my own hands' by taking him home, and so they didn't bother to show up for a statement. When I returned home, my wife and I looked at each other as we both said in unison _We're getting a fucking dog!_ One week later, we picked up Raz. Three weeks later, our late-nite visitor got picked up for B&E, and so he ended up in prison. So much for second chances. Moral to the story? There's no madness like meth, kids. Stick to margaritas and mild psychonautics.
@@pocket83squared Wow, that sounds intense indeed. I was lucky this was a girl, and she was over a foot shorter than me. I had my dog with me for alerting purposes when I went out to the screams, so you're absolutely right that a dog will help in that regard (although iirc you don't have immediate neighbors who would come outside towards the barking like I do). Just having my dog there allows me to focus on the intruder rather than having to find ways to call for help... (still her super loud bark was unable to penetrate the headphones of the Fortnight playing neighbor hahaha) I really don't know much about this drug because it's so rare here. Is it one of the drugs that increases the user's strength and lowers their pain sensations? Or is it one that makes them rather unbalanced like alcohol does? I guess knowing that kind of stuff might influence my reaction in case one of them would try to get physical.
@@lukearts2954 So far as I understand it, (meth) users remain reasonably non-violent, although they may become stuck in a complete delusion. So I'd prefer to keep my distance. Now that I think about it, the drug whose users tend to become _the most_ dangerous is likely alcohol. Man, can a few drinks flare up a situation!
@@pocket83squared You are _ABSOLUTELY_ right there... Medication forced me to stop consuming, and since then I've been seeing more and more what a problem it has become (or perhaps always was) in society. Currently main stream media are hyping the consumption of alcohol, pushing the idea that it's impossible to have fun without it. They are using the strategies of the tobacco industry from back in the days where they were unrestricted. And then my accident happened because of a drunk driver. And when my son was 10 months old, we were attacked on the street by another drunk driver who felt that we didn't cross the road fast enough so he had to grab my cane and smash our heads (yes, he aimed for the baby's head too, but luckily my reflex was to curl up around him as a human shield, and just endure the beating until somebody would come and intervene. Which took easily 5 minutes of nonstop being kicked in the ribs and beaten over the head and back with my own walking cane. (The cane was all bent from it) So yes, I have come to see alcohol as public enemy number one. (and then there's the health issues too)
My trampoline coach got her leg sliced up by a spring like a knife through spam, it can get really gnarly, and she was a very experienced athlete with an Olympic career.
@@pocket83squared Positive thinking and action is everything. I want to personally thank you for putting me onto sacred proportions and in finding the beauty in geometry. It really shaped the man I am today. My dad being into Tool helped a lot too lol
I had a similar situation but it was the tip of the hook on the apring broke due to rust and flew ejected and hit my boat really hard. I think inspecting thw tranpoline monthly is necessary. Im thinking about doing what you did but tying the cord to rhe springs too.
Good video! Thanks! My trampoline springs keep snapping where they sit inside the outer frame holes. I drilled the holes to remove the sharp edges, but they soon reappear, and broken springs start flying off again. Maybe brass or hardened steel eyelets would solve this? Or heat treat and harden the soft steel frame so the holes don’t wear and form sharp edges? Or thick bicycle tubes? Thoughts? I fear and hate springs!!
That is a tough problem. Honestly, it might be prudent to simply find a different brand of trampoline, but I'll take a shot at it. First thought is to use a sacrificial link, a go-between, like a single piece of chain that connects the frame to the springs. It would fix the problem, BUT-two new problems arise: 1) that's a lot of chain cutting, and 2) now the trampoline canvas will be under less tension. Problem two might not be a problem. Another idea: If the springs are all breaking at the same place, it may be that the springs themselves were tempered too hard. If I remember correctly, when spring steel is heated up, it becomes less brittle, but it also looses its springiness. Test with one first, but maybe you could try hanging a few springs from a coat-hanger, and hitting them with a blowtorch (right at the spot where they break) until the weak spot briefly turns almost red. The reduced temper might make the springs more snap-resistant at that spot. Careful not to torch the springy part of the spring itself. And hey, if nothing works, the second-hand market is filled with cheap trampolines. Good luck.
Is there an adhesive you could splurge into the pocket with the tab of fabric holding the metal attachment point to speed up the repair by avoiding the need to stitch?
Not one that I'd trust. Adhesives just don't fare well where there's mechanical action. Classic case is trying to repair a detached shoe rubber: I've met nothing but failure.
@@pocket83squared I'm with you on the shoe rubber. I tried to keep some expensive mountain boots going once, but of course you take boots like that to precisely the kinds of places where you really need your footwear to stay in one piece.
I was going to ask how the spring got through the spring cover, but the gaping hole answered that question pretty summarily. The question now is what use is the spring cover if it doesn't contain spring explosions. I guess it protects the springs from direct rain? If the spring can break through it, I'd imagine a child's wayward foot could as well, so it's not even protecting ill fated trampoliners from an unfortunate fate.
A snap-launched spring will have a much higher force-per-area than the average foot. It's also a somewhat uncommon event. The spring cover's main purpose is to stop a person from getting their leg stuck between two springs, and for this purpose I must admit to finding the thing pretty effective. I've been walking all over mine for years, and not once have I stepped through it. Most trampoline (spring) covers involve a polyethylene foam nested inside of a polypropylene case; all three layers together end up making it surprisingly tough, especially over the short distance between two springs. Consider that springs are not under tension during any moment in which you're making foot contact with the cover (assuming a single jumper). Also note that where the spring shot through mine was on its frill, where it's only got a single layer of tarp.
I’ve recently watched a few videos about reusing old trampoline frames and turning them into sheds or other building framework. Do you have any thoughts? The videos are inspiring, but none I’ve seen go into the kind of detail that makes me confident enough to go for it. If you made a video, I know I could do it.
@@pocket83squared these are the 3 that inspired me the most “CIMG2016Metal Building Frame made from Trampoline frames by Old Geesers Workshop” ua-cam.com/video/29Wh65e_UJs/v-deo.html “How to build a High Tunnel using Trampolines by Sweenies Creek Farm” ua-cam.com/video/HnNqCYt6xI4/v-deo.html “Trampoline Frame Storage Shed by ShapooTube” ua-cam.com/video/6jJReE7aS00/v-deo.html
The other thing that you can do is screw a countersink head machine screw into the hole after the spring is in… I had access to hundreds of these but paracord not so. It means that the spring cannot easily come out even when you try to take it out, without angling it way down. Even then depending on the size of the hole and where you put it in sometimes it becomes impossible for the spring to come back out, without backing screw out. Stainless steel is best or galvanised. Countersunk does really add any height and certainly not above the height of the spring.
Um, okay. That _will_ work. Now consider the practicality of recommending this to a mass audience: 1) how much do 96 countersink-head screws cost at retail, and 2) how on Earth am I going to find time to disassemble that every year? From what I understand about my over 2K views audience, it'll be hard enough for most of them to find a needle, a lighter, and some pliers. Let's keep it simple, eh? And if you have internet access, that means you also have access to paracord, too.
@@pocket83squared As I said, I had access to them... looking on internet I can buy 50x hex-drive M5x16mm for £3.99 (100x zinc coated hex-drive M5x10mm for about £6 delivered)... It wouldn't take long to whiz them all off with a driver but as I said if you place them correctly then you are just shortening the slot and you can leave most of them in after tension is removed and still get the springs out... I appreciate your video though and it is a great idea and love people like yourself who fix rather than replace - I am a long time viewer of yours and love that about your channel... I really didn't mean to offend, it was just a suggestion that worked in my case but even as a belt and braces approach I will probably do your way as well in future as i've seen these springs snap where they meet the buckle and the frame (which is quite sharp), due to fatigue...
@@smitcher No offense taken at all. Just explaining my reasoning. If I were in your exact shoes, I'd see things exactly your way! Many ways to skin a cat ;)
I Always pick up thrown away trampolines because the components have been so Useful. I am currently making a Chicken train from one. But It appears that your tarp has shrunk , those springs appear over stretched at rest as compared to what I normally see.

@@pocket83squared Brother, You have inspired me since the first videos working out of that closet size shop. Back when we watched the reflections to just get a glimpse of this genius with the silky voice.
That does look rather dangerous! It cracks me up that you have a trampoline. Dog on trampoline, nice. People have been asking why you have a trampoline. People have been asking if you ever use a speedy switcher. People have also been asking if you learned that knot rock climbing.
Red, green, and blue. There's two of each colored spring, and two of each colored spots on the frame that correspond. It helps to speed up the (yearly) setup.
mmh.. i rember when my dad got us a trampoline, he accidentaly crossed two of the springs and he decied to fix it, me and my sis was hiding under the trampoline but he told us to go away from there and stand a bit away from it. when he pulled the spring and launched off straight into my sisters head and caused it to spin and slash open my ear. so i have a pretty good idea on what one of those springs can do, lmao.
That sounds like a great idea, but it might not be waaaay easy, because you'd have to stick your head around to the other side of the springs with each pass in order to feed the thread back through into the stitch. Also, I think we replaced two last year. I'll definitely consider it, though. Thanks.
How about using zip ties. Doctor's caution trampoline as the worst thing for kids and adults; however i think it may depend on the actual monkeying around on it.
Zip ties are extremely susceptible to UV degradation. That, and they probably aren't strong enough to withstand the force of a spring-snap. As for trampoline danger, well, it's also about the most fun a kid can have, and it's an actual physical activity, which alone probably makes it worth the risk. At the risk of sounding negligent, encouraging a life without risk _is_ negligence. That said: supervise, supervise, supervise!
Thanks for this.. Not because I’ll ever repair a trampoline, but because it’s a video about spending a lot of time fixing a thing that is easy to replace. You could make the same video about putting a new drawer slide in an Ikea cabinet. Things can be fixed, and giving it a try is low risk if your intention was to replace it anyway.

For the 8 figure knot, I thought that you were going to follow the first 8 figure with the other end of the rope, not with the same end. So you would end up with one knot and not two. Does that make a difference (apart from having a harder time tightening the rope when you have only one knot) ?
Also if someone uses the rope solution, you need to tighten the rope at least a little bit, because I think there might be a scenario where having a non tightened rope can allow the spring to still gain some momentum and then be able to escape the triangle with speed.
The paracord loop only needs to be snug, because _it_ acts as an inertia absorber when it grabs a launched spring. Some give here is good; think of it as being like a fireman's net (a life net). If an object in motion is stopped too quickly, often the 'equal and opposite' reaction instead becomes manifest as an equal and opposite motion. We don't want that. Elastic collisions are great for billiards, but not so good for catching falling people or projectile springs. If the loop were metal instead of cord, it might allow a spring to preserve and thus redirect its motion toward the person who's bouncing.
The figure eight:
tying two knots to one triangle was as simple as I could make it. Not only is the knot mass reduced, but the knots will be less likely to come undone than a rope-to-rope circuit knot, and it's also easier to visually inspect. Oh, and it's easier to describe on camera.
Nylon strap's tiny surface-area contact with mat:
normally, the amount of tensile force placed upon an individual spring is kinda small. I don't need to explain to you the mathematical dissipation of a 300-lb force over 96 parts, but let me say that our natural intuitive sense will tend to overestimate just how much work a trampoline spring is usually doing.
-----
How did I know that the solution would work before actually testing it? Okay, this point is your most interesting bit of skepticism. I appreciate it, and I want you to really listen to me here. You've probably heard me preach before that there are two types of knowledge, _a priori_ and _a posteriori._ This is just the difference between the imagined and the observed. We scientific-types tend to scoff at the former. We want evidence.
When I was young, I was strictly empirical, rigorous. Imagining an experiment can't be as trustworthy as running the actual experiment, right? But now I understand _how to imagine_ much, much better. Let me explain. My gamble here was with potential lost time, and I could've also been filming a useless video. This is, except that I was extremely thorough with my _a priori_ reasoning. One can learn to run experiments in one's head well enough to prove, mathematically, or logically, within a reasonable expectation of error, many of the world's basic physics problems. Point is, as you gain skill as a practitioner of empiricism, don't lose sight of the incredible real-world utility of reason. Though there can be no certainty in forethought, I was _certain enough_ to wager my time and video, knowing that it was a safe bet.
Try it. Imagine the spring's motion in your head. Replay it in slow motion, and try to account for everything that is likely to happen during the event. One can get better and better at doing this with practice. Just remember error. Account for your personal biases. And be mindful of your own arrogance. Remember how during the second trial the spring caught the other triangle? Though it wasn't quite relative to the outcome, I still didn't see that coming.
@@pocket83squared Hi, thanks for taking the time to answer :)
I love that flow from priori to posteriori. Even in empiricism we can't escape priori knowledge : what experiment should I run ?
I'm still young, but I out grew my extreme skeptic phase. I'm still skeptic, but more like practical skeptic. Sometimes (well almost always) you can't test everything nor can you head to the right direction right away, and that gave me so much frustration in the past, because everything felt like moving mountains while being a tiny little dust. I always wanted to get things done correctly (perfectly ?) from the first try. Sometimes this behavior annoys me so much that I go to the opposite side and improvise too much to the point where I'm even more frustrated from the lack of control and so I don't learn anything because I didn't evaluate my priori to compare it to the results.
Now that I have a job, being an extreme skeptic is just unthinkable of (well I still allow myself sometimes to be a moderate skeptic, I either lose time or I gain something precious). We lack so much time that we "just do the thing, if it works great, if not now you know that it doesn't" (we don't build nuclear power plants so no worries !), as you said, we are constantly betting. We don't have the time to apply the theory, we rather apply the practice to the theory, by updating our knowledge as we succeed or fail.
This way of doing things is so much opposed to the way I always used to think that it can be frustrating for me and I have to force myself to do it that way because it's what works best. I'm still very thankful for my job, I have never been able to learn that much before. I was always struggling with theory and always thought that it was right way to do and learn things.
Of course I'm not saying by any mean that theory is useless or some other thing.
I hope what I wrote makes sense and is related to your reply (if it doesn't, in my defense I was too tired when I wrote this hehe)
Again, thanks for your insights, it makes me think and wonder :)
The cable in garage door springs is to capture the fragments if the spring breaks? That's truly a new bit of knowledge I gained today :) (scouts honour, not being sarcastic, even though it really looks like it... Deng it, now it looks like it even more... But it isn't. I swear.) I always thought they were a dead stop to prevent the door to ride off the rails in case the spring gave, or if the spring stretches on the way down, so that the door would slam shut and possibly crack, but not leave the facade, frame and all... I would think the most dangerous fragments of a spring breaking from fatigue, would be the tiny fragments that shoot out to the side, perpendicular to the pulling axis... (I remember those from the metal rods we pulled to the point of destruction in the tensile strength lab tests back in my college days)
Oh well, what do I know... Watching this video I got brutally interrupted by the dying screams of a young woman. As I ran out, I found a woman curled up in my neighbors enclosed front yard in the corner against the fence between our properties, panting and screaming... She stated that her dad was chasing her with a shot gun... Called the cops. As they got out, the first cop that approached her (a lady cop) said: "But... Julie, we just dropped you off at your dad's house this morning..." (meaning that she had already spent last night in their custody for something) She had also claimed that the guy with the rifle/shotgun had entered my neighbor's house. A quick call to him fixed that issue. The man was playing Fortnight and hadn't heard her climbing his fence while screaming at the top of her lungs...
Yep, I'm guessing XtlMeth has found its way to the mainland... (i.e. Europe.) Never had an encounter with someone on a meth high, so I didn't recognize it at first and took all of her claims seriously. Until she claimed that her father owned all our houses and that the cops were corrupt and in league with everybody in our street... Then I knew she was either an escapee from a mental institution or a drugged up user or something... Cops took her with them when their backup arrived. So they know her, _and_ they know to bring 4 officers when they have to drop her off at home. I think that says something...
Now I have the terrible task of coming down this adrenaline high hahaha. I guess I'll have to rewatch some more pocket content. (not that it makes me sleepy, because they usually make me think more. But he's got one of the most calming voices of YT vloggers in my subscriptionlist)
We once had a visitor here who was on crystal meth. He stopped in at 3 AM on a July Saturday wearing no clothes except for a loose beach towel. He didn't knock, but I'd heard him cough from the front porch since the windows were open. The guy was kinda tough-looking, a little scummy, and probably 10-15 years younger than me. Naturally, I decided to stay inside and try to calm him down through the window; I didn't tell him that there was a pistol being pointed at him. I wasn't as soothing as you might think; I was being pretty stern, almost forceful, probably too much, but he seemed to respond better to demands. Note that I'm in full adrenaline rush and trying to avoid a fight.
After I'd talked him into sitting down on the patio, I gave him a bottled water as an olive branch, and got him to become almost sane, that is, until he went into a frenzy when an owl hoo-HOO-hooted, screaming that the sound was coming from "them!" (even though he knew I wouldn't believe it).
The poor guy was terrified. He eventually admitted to smoking meth, and he just wanted a ride home since he was out here in the middle of nowhere walking barefoot through the dark. My wife had already quietly called the cops, and so I told the guy that he had two options: either he could stay here and wait for them to give him a ride, or I could give him a ride now in the back of my pickup truck. He was insulted, but I insisted to him that there was NO WAY a naked stranger was getting in my truck while high on meth. He reluctantly agreed, but then bitched the whole way home (about three miles). Before the truck even stopped, he jumped out of the bed as we got near his house. He then ran into the bushes around his neighbor's house, apparently to resume hiding.
The cops became uninterested in this story after I decided to 'take the law into my own hands' by taking him home, and so they didn't bother to show up for a statement. When I returned home, my wife and I looked at each other as we both said in unison _We're getting a fucking dog!_ One week later, we picked up Raz. Three weeks later, our late-nite visitor got picked up for B&E, and so he ended up in prison. So much for second chances.
Moral to the story? There's no madness like meth, kids. Stick to margaritas and mild psychonautics.
@@pocket83squared Wow, that sounds intense indeed. I was lucky this was a girl, and she was over a foot shorter than me. I had my dog with me for alerting purposes when I went out to the screams, so you're absolutely right that a dog will help in that regard (although iirc you don't have immediate neighbors who would come outside towards the barking like I do). Just having my dog there allows me to focus on the intruder rather than having to find ways to call for help... (still her super loud bark was unable to penetrate the headphones of the Fortnight playing neighbor hahaha)
I really don't know much about this drug because it's so rare here. Is it one of the drugs that increases the user's strength and lowers their pain sensations? Or is it one that makes them rather unbalanced like alcohol does? I guess knowing that kind of stuff might influence my reaction in case one of them would try to get physical.
@@lukearts2954 So far as I understand it, (meth) users remain reasonably non-violent, although they may become stuck in a complete delusion. So I'd prefer to keep my distance.
Now that I think about it, the drug whose users tend to become _the most_ dangerous is likely alcohol. Man, can a few drinks flare up a situation!
@@pocket83squared You are _ABSOLUTELY_ right there... Medication forced me to stop consuming, and since then I've been seeing more and more what a problem it has become (or perhaps always was) in society. Currently main stream media are hyping the consumption of alcohol, pushing the idea that it's impossible to have fun without it. They are using the strategies of the tobacco industry from back in the days where they were unrestricted. And then my accident happened because of a drunk driver. And when my son was 10 months old, we were attacked on the street by another drunk driver who felt that we didn't cross the road fast enough so he had to grab my cane and smash our heads (yes, he aimed for the baby's head too, but luckily my reflex was to curl up around him as a human shield, and just endure the beating until somebody would come and intervene. Which took easily 5 minutes of nonstop being kicked in the ribs and beaten over the head and back with my own walking cane. (The cane was all bent from it)
So yes, I have come to see alcohol as public enemy number one. (and then there's the health issues too)
My trampoline coach got her leg sliced up by a spring like a knife through spam, it can get really gnarly, and she was a very experienced athlete with an Olympic career.
Great stuff my man. It seems you're living your best life :D
Thanks. We're trying.
@@pocket83squared Positive thinking and action is everything. I want to personally thank you for putting me onto sacred proportions and in finding the beauty in geometry. It really shaped the man I am today. My dad being into Tool helped a lot too lol
I had a similar situation but it was the tip of the hook on the apring broke due to rust and flew ejected and hit my boat really hard. I think inspecting thw tranpoline monthly is necessary. Im thinking about doing what you did but tying the cord to rhe springs too.
Hello! Dont mind me watching ads til the end💜
Good video! Thanks!
My trampoline springs keep snapping where they sit inside the outer frame holes.
I drilled the holes to remove the sharp edges, but they soon reappear, and broken springs start flying off again.
Maybe brass or hardened steel eyelets would solve this?
Or heat treat and harden the soft steel frame so the holes don’t wear and form sharp edges?
Or thick bicycle tubes?
Thoughts?
I fear and hate springs!!
That is a tough problem. Honestly, it might be prudent to simply find a different brand of trampoline, but I'll take a shot at it.
First thought is to use a sacrificial link, a go-between, like a single piece of chain that connects the frame to the springs. It would fix the problem, BUT-two new problems arise: 1) that's a lot of chain cutting, and 2) now the trampoline canvas will be under less tension. Problem two might not be a problem.
Another idea:
If the springs are all breaking at the same place, it may be that the springs themselves were tempered too hard. If I remember correctly, when spring steel is heated up, it becomes less brittle, but it also looses its springiness. Test with one first, but maybe you could try hanging a few springs from a coat-hanger, and hitting them with a blowtorch (right at the spot where they break) until the weak spot briefly turns almost red. The reduced temper might make the springs more snap-resistant at that spot. Careful not to torch the springy part of the spring itself.
And hey, if nothing works, the second-hand market is filled with cheap trampolines. Good luck.
@@pocket83squared
Good suggestions! Thanks!
Is there an adhesive you could splurge into the pocket with the tab of fabric holding the metal attachment point to speed up the repair by avoiding the need to stitch?
Not one that I'd trust. Adhesives just don't fare well where there's mechanical action. Classic case is trying to repair a detached shoe rubber: I've met nothing but failure.
@@pocket83squared I'm with you on the shoe rubber. I tried to keep some expensive mountain boots going once, but of course you take boots like that to precisely the kinds of places where you really need your footwear to stay in one piece.
If faced with the same repair, I would have included some epoxy. Probably overkill.
i did have one query how long or well does paracord last out in the weather
I was going to ask how the spring got through the spring cover, but the gaping hole answered that question pretty summarily.
The question now is what use is the spring cover if it doesn't contain spring explosions. I guess it protects the springs from direct rain? If the spring can break through it, I'd imagine a child's wayward foot could as well, so it's not even protecting ill fated trampoliners from an unfortunate fate.
A snap-launched spring will have a much higher force-per-area than the average foot. It's also a somewhat uncommon event. The spring cover's main purpose is to stop a person from getting their leg stuck between two springs, and for this purpose I must admit to finding the thing pretty effective. I've been walking all over mine for years, and not once have I stepped through it.
Most trampoline (spring) covers involve a polyethylene foam nested inside of a polypropylene case; all three layers together end up making it surprisingly tough, especially over the short distance between two springs. Consider that springs are not under tension during any moment in which you're making foot contact with the cover (assuming a single jumper). Also note that where the spring shot through mine was on its frill, where it's only got a single layer of tarp.
I’ve recently watched a few videos about reusing old trampoline frames and turning them into sheds or other building framework. Do you have any thoughts? The videos are inspiring, but none I’ve seen go into the kind of detail that makes me confident enough to go for it. If you made a video, I know I could do it.
Let me scratch my head over that thought for awhile.

great ideas!
Thank you ;)
what wire did you used and what thickness?
That was just a scrap of 12 gauge copper electrical wiring. Note that it still had its insulating jacket on.
The other thing that you can do is screw a countersink head machine screw into the hole after the spring is in… I had access to hundreds of these but paracord not so. It means that the spring cannot easily come out even when you try to take it out, without angling it way down. Even then depending on the size of the hole and where you put it in sometimes it becomes impossible for the spring to come back out, without backing screw out. Stainless steel is best or galvanised. Countersunk does really add any height and certainly not above the height of the spring.
Um, okay. That _will_ work. Now consider the practicality of recommending this to a mass audience: 1) how much do 96 countersink-head screws cost at retail, and 2) how on Earth am I going to find time to disassemble that every year? From what I understand about my over 2K views audience, it'll be hard enough for most of them to find a needle, a lighter, and some pliers. Let's keep it simple, eh?
And if you have internet access, that means you also have access to paracord, too.
@@pocket83squared As I said, I had access to them... looking on internet I can buy 50x hex-drive M5x16mm for £3.99 (100x zinc coated hex-drive M5x10mm for about £6 delivered)... It wouldn't take long to whiz them all off with a driver but as I said if you place them correctly then you are just shortening the slot and you can leave most of them in after tension is removed and still get the springs out...
I appreciate your video though and it is a great idea and love people like yourself who fix rather than replace - I am a long time viewer of yours and love that about your channel... I really didn't mean to offend, it was just a suggestion that worked in my case but even as a belt and braces approach I will probably do your way as well in future as i've seen these springs snap where they meet the buckle and the frame (which is quite sharp), due to fatigue...
@@smitcher No offense taken at all. Just explaining my reasoning. If I were in your exact shoes, I'd see things exactly your way! Many ways to skin a cat ;)
I Always pick up thrown away trampolines because the components have been so Useful. I am currently making a Chicken train from one. But It appears that your tarp has shrunk , those springs appear over stretched at rest as compared to what I normally see.

Why are some of your springs painted blue?
Red, green, and blue. There's two of each colored spring, and two of each colored spots on the frame that correspond. It helps to speed up the (yearly) setup.

sewing awl my friend...., waaaay easier than sewing needle and thread especially when you're replacing 1 a week
That sounds like a great idea, but it might not be waaaay easy, because you'd have to stick your head around to the other side of the springs with each pass in order to feed the thread back through into the stitch. Also, I think we replaced two last year. I'll definitely consider it, though. Thanks.
@@pocket83squared done it a few times and the thread is thicker. every stitch locks and is stronger
How about using zip ties. Doctor's caution trampoline as the worst thing for kids and adults; however i think it may depend on the actual monkeying around on it.
Zip ties are extremely susceptible to UV degradation. That, and they probably aren't strong enough to withstand the force of a spring-snap. As for trampoline danger, well, it's also about the most fun a kid can have, and it's an actual physical activity, which alone probably makes it worth the risk.
At the risk of sounding negligent, encouraging a life without risk _is_ negligence. That said: supervise, supervise, supervise!
