Thank you for having all these great ideas! I built my first Dyneema String today and it worked on the first try! Even the tool ideas were great help! Without Joerg we would still throw stones by hand. Carry on doing that stuff! You are the grandmaster of accelerated anythings!
As a professional amateurist archer since the age of 5 I guess, and making my own bows, arrows and crossbows since the age of 7 or so, now that I am 55 years old I can confess to you all that this is the first time I hear about dyneema strings. By the age of 15 the kitchen string (cotton) was already not good enough to me, my weapons started to pull more towards 50 Lbs of force, and I was doubling them, trippling them, than it became bulky... so I used bicycle brakes cable, stainless steel or steel, as I find them in the shops. Done so for decades, the 4 mm and 6 mm brakes cables worked miracles, good in time, holding thousands of shoots before getting damaged, just nasty to splice to form the eyelets, but I got used with the idea and spliced them like a boss for decades. I also learned that if I place inner eyelts metal protections that section can last longer, and if I put arrow/trigger spot protection (like a short tube) to mitigate fricton, the result is longer life. I shall assume Dyneema too, if protected in those 3 points (inner eyelts and trigger/arrow friction point) might last longer too. Besides looks far easier to splice. I am ordering some now, time to go modern.
This is HUGE!! something so simple nobody saw before!!! braided vs parallel strands. You have given the archery world most than anybody else in the last 40 years!
Ten days ago I had never heard of Dyneema, I'm already convinced enough to give it a try! And I just got my siege too! Joerg, you are one of my favorite people on the net! Keep it up!!
Watched your video on revolutionary string several months ago and all I can say to you is thank you thank you thank you, you’ve saved me so much money that I can afford to buy the magazine for my siege crossbow so it’s true what they say what goes around comes around.keep laughing
Recently obtained the RX ADDER, I literally obliterated my targets at 30 feet and had to step back away more distance because I damaged too many bolts. This weapon is unbelievably awesome! I've been watching these videos for 3 years all the way working up to it and finally got one. They are very accurate when you set your sites proper and the power is unbelievable. Thank You Joerg on your expertise and innovations!!!!!!
There is another Archery channel that was trying different types of bow string options and he was using Dynema braided line to make a traditional multi loop type bow string, he was successful hand happy with the results.
Awesome job Joerg, but now you've really gone and done it. I'm sure there are some corporate board of director people now screaming "No! He reveled the Dyneema secret! Now we have to start using a higher grade material in the construction of our bow strings and that's going to cut our profit margins. We made so much money making inferior bow strings but now people will know how to make better ones and stop buying ours if we don't change." Trust me people, I've worked in the manufacturing sector for over 30 years. This is actually what happens. The old idea of building something to last was suppressed and killed off by corporate greed.
They'll just release new additions of their existing crossbows with the Dyneema under a different name and act like it's some magic space-age technology they invented and charge you 50% extra.
They will stat voiding warranties for people using anything other than their proscribed bowstring and make it out to be a safety issue. Danger! You risk severe injury or death if you use anything other than our own brand bow string.
When you talked about Dyneema the other day, I had a feeling I would be seeing it again. That is awesome stuff. Great work there. I'm sure the people at Dyneema love it as well. Best of Days.
Du bist nicht nur mein lieblings Erfinder, du bist auch ein wunderbare Mensch, du hilfst Menschen . Deine Tipps sind extrem wertvoll und ich mag dich sehr Joerg
Hey Joerg, you really had another great idea. If you take a second small piece of the same material for the middle part, the service life can be extended almost indefinitely, you just have to replace the middle part in good time after maybe 250 shots, but that happened quickly with the material... keep it up, Andreas
I wonder if you can swap over (from having the loose end of the eye inside the structural strands) to having the structurally loaded middle section inside the loose end... You'd just end up with a few millimeters where the two directions of the rope run side by side, but I guess for most bows/crossbows there should be a point where that doesn't get in the way of anything. As far as I can tell, it should be relatively trivial if you do this extra step on the first loop and then finish the second one as shown. Affixing the loose end of that sleeve section could even be a larger issue. I don't know if you could just use glue... If not, you could always swap them a second time.
Die Armbrust hat sich über 2000 Jahre kaum geändert, ebenso wenig die Sehnen. Doch in den letzten 30 Jahren oder so macht die Armbrust-technik einen Quantensprung nach dem anderen. Ich komme mit ausprobieren kaum noch nach. 😉 Klasse Video 😁 Danke.
As a sailor I know Dyneema since a few years now, we use it as stays to hold really powerful rigs on racing boats. Using it on my pistol crossbow was a no-brainer. I wet sand with 2000 paper my rail and wax it as well as it gives some extra life to the string.
Sanding the rail sounds like a good idea, can you use this stuff ok on pistol crossbows as I have 3& a cobra r9,it would save me money learning this & im not sure about the sanding,which pistol crossbow
You Sir are a Legend and somewhat of an Einstein in my books. Glad I discovered you on RUclips and your knowledge is always welcomed as it sorts through the B.S. and gives honest facts. As for this latest video im very grateful as in times of say SHTF then the splice method you have described will help no end in the manufacture and repair or saving of constant string repair or no supplies if in SHTF scenario. Ive just ordered me a Cobra R9 system with your patented auto load design and im sure I'll have many hours of reliable fun and target bashing. Thanks for all your Videos, keep up the good work and credit to you for being such an awesome engineer!
Crossbow strings generally last 1-2000 shots if they’re made well as I understand… it’s recommended to change every two years regardless. I think repeating crossbows are different- that lower poundage and higher cycle rate of stretching probably suits a braided line better.
thats only if you shoot 200-300fps under 170ftp, as soon as you hit 380fps with 200lb limbs, you need to be an expert to get over 1000shots with an high quality string
I've been using dyneema for my compound bow for years everybody tells me I'm crazy thank you for validating that I am not crazy as I am using every precaution that you are using and one by adding one additional sleeve of dyneema to the center and then serving it into place with a stitch serving not just a regular serving and of course I always verify that I am not splitting any of the threads and I keep the count as clean as possible equal on both sides whenever the dyneema or the serving splits the dyneema. And yes originally I started with parachute string but it was just not quite strong enough to do the job
Hi barretharms.i just came across your comments about using dyneema cord for your compound bow,what thickness cord did u use and how did u install your peep sight on the string.would appreciate any help you can provide.cheers Rene,from Vic,Aus.
DD hammocks in the UK, sell's Amsteel/Dyneema by the metre,. about a £ per M thin plastic coated garden wire is handy for splicing / pulling the string through for a bury,. also see some tuts for making whoopie slings,. as they cover useful techniques. brummel knot/ bury.
I kinda want to see how it works on a recurve bow. This had single handedly improved archery by a lot, imagine if your rifle broke or deformed heavily it's firing pin every 10-30 shots, good stuff Joerg!
Great video Jörg! As I own the fenris setup with the greyback bow... I ofc wonder if this is possible to make one as a bow string? They attach to the bowlimb a bit differently I see, will you make a tutorial in some sort for compound bows as well?
I am sure it works for bows too, but I would probably use the 2mm type. But for a regular bow, you probably need to thicken the middle part so the nocks will still hold on.
@@Slingshotchannel Could you pull a regular bow string through a little section of this Dyneema cord over the middle serving? It would protect the regular serving of the string, but woul be much easier the replace when worn, than a complete reserving of the bow string. Using your copper wire technic. The string would of course become a little more thick though, but you could strech adequatly or eventualy use this option INSTEAD of serving the bow string?
I am not sure there is much use of it in bow since bows have much lower forces than crossbows. One thing i like is that it seems its easier to make dynema string than regular bow string.
Also, if you don't loop back through the loop (above where Joerg says some people do but I don't) it can pull back thru if not under tension, thus making the loop bigger & ruining the length (as it's quite slippy).
I had some problems with the eye serving of my bow recently and I am unsure how to repair that. As a relatively new archer I would love to not worry about my string and it's maintenance. So I will try this with my olympic recurve and see how well it works.
Thank you so much, and I really mean that, for this instructional video on the string. I have a spare string for my crossbow pistol but I can't seem to find it. The one I have on it is still good but I would like to make another just in case I can't find the spare string that I have. So again thank you so much for showing this it really is going to be a great help for my little crossbow pistol. You make cocking these things look so easy because I think you are a strong man and as I am 71 years old and muscle atrophy has kicked in, well cocking is not as easy anymore. So thanks again very very much for this video as it was most helpful in learning how to build a new string, thanks again have a great day and stay safe and keep your powder dry and your strings strung! And may God bless.
Dyneema is amazing in its hollow braid configuration for splices (like Joreg shows), but it is also widely used as a core for many ropes. Many rope companies will use an Aramid outer sheath (like Technora) for abrasion resistance combined with a dyneema core for even more resilience. Technora is another wonder material. Its like Kevlar, but on steroids. It has a much higher melting point and good abrasion resistance, so its great as a outer protective sheath and is almost as strong as SK-75 or 78. Definitely a good one to check out.
The Kanirope guys actually put a coating around each strand before it is woven, which makes it perfect for the task. Abrasion and sunlight is no problem for this rope.
@@Man_fay_the_Bru doubt that aramid would be used for climbing because it doesn't really stretch and you need that quality in climbing rope to keep it from injuring you if you fall
I was recently looking around for material to make bow string for the bows I have. And this video might have just offered the solution. Thank you so much
Thanks for this video Joerg! I have been struggling for some time to thread through braided cord, and your DIY tools may just do the trick! My use for spliced cords is whoopie slings for suspending a hammock while camping; one end is spliced as you show with three or so pass throughs. But the other is only buried through a length of about 15-20cm once. This allows it to slip though when unloaded and the length to be adjusted. I got so frustrated with my attempts to splice I researched kumihimo, a Japanese braiding technique (lots of videos online). While I can achieve the same thing, it takes way longer. It does offer more opportunities tho. Thanks for all your great videos!
Joerg, it has always been a pleasure watching your channel. I work in IT and catch myself when explaining something with the urge to say "Let me show you all its features" thanks to you 😂. I have been a fan for a long time. Furthermore, I don't have a crossbow or bow yet, but the problem I have is getting it past my wife 😏. But ever since I saw you showing your Legolas bows, I was hooked. I was thinking, I really hope he gets a patent, and makes millions, he truly deserves it. You have a passion for it, which I respect (I like to tinker too which I tend to do, but with much less success... ahem). Anyways, I wanted to express my appreciation and always look forward to seeing what you're doing next. When I do finally manage to finagle my way into getting a bow or crossbow, it's going to be GOGUN 😉. BTW, cool idea with the replacement string. I had no idea that's how it's done, video saved for future reference. I could easily apply it to other things too. It also looks strong and very neat without the knots sticking out. Keep up the good work, and I wish you continued success!
I would love to see a comparison video with let's say the siege with the original string and the Dyneema, measuring how many shots it takes for each to break :D
Why not download it then? I download every "how to" I think I might need to use latter. Mostly machining videos in my case, got quite a handy reference library now.
I'm a newcomer in crossbows and slowly learning in this field, Your videos are very entertaining and a very learning experience! I hope you make Billons on your new Product!
About 15 years ago, I met a weaponsmith at Cornel University that had made a miniature crossbow (8 inches long w/ a 6 inch armature) that had a 500 pound draw. It needed a screw winch to arm it. It shot toothpick sized steel bolts, that could punch through a quarter inch piece of plywood like it was tissue paper. I bet he'd have loved the weapons you make!
gut überlegt , sehr gut gemacht und nett , es anderen leuten so anschaulich zu demonstrieren ! well thought out, very well done and nice to demonstrate it to other people so vividly
Thank you for the technique and material to make a virtual foreverbow string of any length.. You have helped archerty nemisis once again . You are an engineering genius.
I bought the adder crossbow from your very 1st shipment, and it's awesome. Do you have plans to sell the dyneema replacement strings on your website in the future? I would absolutely buy some replacement strings.
I dont know anything about archery, but i have a little engineering experiance. My question is what does a Dyneema bow string failure look like, and how does that compare to a traditional bow string? It seemed like the original bow string showed visible signs of wear and tear as it was reaching the end of its life. If the dyneema fails suddenly and catistrophically withiut visable warning signs, i could see that as a potential safety hazzard, even if it is a more durable string overall.
It starts to fray a bit and this gets worse. So you have a real good way to check on it. Since there is no middle serving, a little fraying is no problem for the integrity of the string. You have 12 strains and EACH one of them can hold the draw weight of a crossbow.
decades ago in collage archery we used kevlar strings that had sudden failure mode (did not even spoil flight of arrow on which string failed). This was on fairly light (target) recurve bows and not a hazard.
Joerg, the serving needed is High powered fishing line,... its used on some Compound bow strings. The recurve crossbow strings I see look like just a bunch of B-50 strands and a cloth serving. But, if you use fishing string for a serving it is much stronger to ware and it protects the string. As for your strings Dyneema I'd add bees wax for added strength. Joerg~ Dyneema is a type of bow string Dynaflight D-97, BCY FORMULA 8125 and DYNEEMA '02 ARE ALL BOW STRING MATERIALS. I'm thinking your Dyneema rope hack is like a Flemish string for Compounds.
This is how engineering used to be, create something that lasts as long as possible. But the archery industry knows that their biggest gain is from people buying strings and arrows again and again. So they have no incentive to fix this ever. Thanks Joerg.
Danke. Du hast mir viel Verzweiflung und Geld gespart. Bei meiner Siege ist die Orginalsehne nach 20 Schuss defekt gewesen. Natürlich kein Ersatz dabei. Das wiederum hieß für mich Sachen Packen und nachhause. Danke dir 🎉
Real 550 cord is probably good enough for a normal bow, and a hell of a lot cheaper than dyneema. Don't just use any random "paracord", buy good stuff with an actual rating online or at a store that specializes in ropes and cordage. You're looking for cord that meets "Military Specification C-5040H". Use some inner strands from a waste piece to do the wrapping at the nocking point.
In the end Jörg destroyed his own business with replacement strings. But his value of being a honorable man has risen ultimately. Thank you Jörg, you are one of the greatest! ❤️ As we say in germany: Ehrenmann!
I already made for my modified 110 lb crossbow using 3 mm dyneema, fixing to buy 6 mm with same specs and build it for my big 175 lb bruin crossbow, I can't thank you enough for this
You lose more than a millimetre on the bow compared to the nails because the circumference of the arch ends is much bigger. I use dowels , just as easy . For proper strength, feather that tail so theres no weak point, not important on an adder but on stronger arches it might be. Bit of trivia, people say they do something to the bitter end. That trailing rope that is buried is called the bitter end, like many things we say, it came from the navy in old days, like between the devil and the deep blue sea ...but the devil is a whole other story from ships not satan :)
Your timing on posting this is crazy. Got my first crossbow about a week ago and already figured out I'll be repairing the serving on the string every 30-50 shots. Can't wait to see what you've found.
youtube needs to (re)render the bigger resolutions, will take some time and the moxe pixel version will be here. It only happens to the "early viewers" ;)
Joerg needs to start SELLING this strings in his store! I (and likely many others who are pressed on time) would gladly buy it instead of making it at home.
Thank you Joerg, I appreciate you a lot. You have introduced to me a great new adventure and a hobby in the best manner possible. This dyneema tutorial is amazing and works great!
Hmm so no serving? I would be quite nervous that it might tear and break the limbs or slash me to the eye... Have you done some further durability tests without the serving on hi-end compound crossbow?
Yay! I now know how to splice a hollow rope for an eyelet😁! Thanks, Joerg! I'm using this technique on my long bows, cross-bows, and bamboo short bows.
So instead of keeping it a secret and making money off a new miracle product Joerg just simply shows you how to do it and where to get it 😎 what a stud... one of my favorite people on earth thanx Joerg your the man.
@@trollmcclure1884 Its not kevlar -kevlar is Dupont(company that polluted west virginia river with teflon making chemicals ) trademark for Poly p-phenylene terephthalamide. While dyneema is trademark for ultra-high molecular weight polyethylene. So its not the same .
@@zumbazumba1 indeed not the same thing. However my point is that you dont need Dyneema brand for ultra-high molecular weight polyethylene. It can be Spectra or just UHMWPE
@@louiscannell6274 It's actually a pretty bad result. It's a good custom that ropes and climbing equipment usually has to withstand at least 30% more than its rating before failing. It's probably your fault tho. Your test was not standardized. It failed in the knot or on the edge of a carabiner. You need at least a controlled setup like the bench used by HowNOT2.

I shall assume Dyneema too, if protected in those 3 points (inner eyelts and trigger/arrow friction point) might last longer too.
Besides looks far easier to splice. I am ordering some now, time to go modern.
This is HUGE!! something so simple nobody saw before!!! braided vs parallel strands. You have given the archery world most than anybody else in the last 40 years!
Ten days ago I had never heard of Dyneema, I'm already convinced enough to give it a try! And I just got my siege too! Joerg, you are one of my favorite people on the net! Keep it up!!
Watched your video on revolutionary string several months ago and all I can say to you is thank you thank you thank you, you’ve saved me so much money that I can afford to buy the magazine for my siege crossbow so it’s true what they say what goes around comes around.keep laughing
You are very much right about that string being the "weakest link" in repeating crossbows. Fine discovery, might bring the over all cost down too.
Recently obtained the RX ADDER, I literally obliterated my targets at 30 feet and had to step back away more distance because I damaged too many bolts. This weapon is unbelievably awesome! I've been watching these videos for 3 years all the way working up to it and finally got one. They are very accurate when you set your sites proper and the power is unbelievable. Thank You Joerg on your expertise and innovations!!!!!!
There is another Archery channel that was trying different types of bow string options and he was using Dynema braided line to make a traditional multi loop type bow string, he was successful hand happy with the results.
Goers RUclips channel has been very helpful over the years. He’s a wealth of knowledge.👍👍
Awesome job Joerg, but now you've really gone and done it. I'm sure there are some corporate board of director people now screaming "No! He reveled the Dyneema secret! Now we have to start using a higher grade material in the construction of our bow strings and that's going to cut our profit margins. We made so much money making inferior bow strings but now people will know how to make better ones and stop buying ours if we don't change." Trust me people, I've worked in the manufacturing sector for over 30 years. This is actually what happens. The old idea of building something to last was suppressed and killed off by corporate greed.
They'll just release new additions of their existing crossbows with the Dyneema under a different name and act like it's some magic space-age technology they invented and charge you 50% extra.
They will stat voiding warranties for people using anything other than their proscribed bowstring and make it out to be a safety issue. Danger! You risk severe injury or death if you use anything other than our own brand bow string.
Or they'll find another component to cheapen and make scarce. Corporate greed.
Yep, only thing capitalism really invented was obsolescence technology.
Capitalism baby!
Such a genius, and making this open source as well.
When you talked about Dyneema the other day, I had a feeling I would be seeing it again. That is awesome stuff. Great work there. I'm sure the people at Dyneema love it as well. Best of Days.
Du bist nicht nur mein lieblings Erfinder, du bist auch ein wunderbare Mensch, du hilfst Menschen . Deine Tipps sind extrem wertvoll und ich mag dich sehr Joerg
Hey Joerg,
you really had another great idea.
If you take a second small piece of the same material for the middle part, the service life can be extended almost indefinitely, you just have to replace the middle part in good time after maybe 250 shots, but that happened quickly with the material...
keep it up, Andreas
I wonder if you can swap over (from having the loose end of the eye inside the structural strands) to having the structurally loaded middle section inside the loose end... You'd just end up with a few millimeters where the two directions of the rope run side by side, but I guess for most bows/crossbows there should be a point where that doesn't get in the way of anything.
As far as I can tell, it should be relatively trivial if you do this extra step on the first loop and then finish the second one as shown. Affixing the loose end of that sleeve section could even be a larger issue. I don't know if you could just use glue... If not, you could always swap them a second time.
Die Armbrust hat sich über 2000 Jahre kaum geändert, ebenso wenig die Sehnen.
Doch in den letzten 30 Jahren oder so macht die Armbrust-technik einen Quantensprung nach dem anderen.
Ich komme mit ausprobieren kaum noch nach.
😉
Klasse Video 😁
Danke.
As a sailor I know Dyneema since a few years now, we use it as stays to hold really powerful rigs on racing boats. Using it on my pistol crossbow was a no-brainer. I wet sand with 2000 paper my rail and wax it as well as it gives some extra life to the string.
Sanding the rail sounds like a good idea, can you use this stuff ok on pistol crossbows as I have 3& a cobra r9,it would save me money learning this & im not sure about the sanding,which pistol crossbow
I love your ability to see problems no one else did, and find solutions for them.
Thank you for all your knowledge, insight, kindness, and entertainment... And for just flat out being awesome. Congrats on your discovery!
You Sir are a Legend and somewhat of an Einstein in my books. Glad I discovered you on RUclips and your knowledge is always welcomed as it sorts through the B.S. and gives honest facts. As for this latest video im very grateful as in times of say SHTF then the splice method you have described will help no end in the manufacture and repair or saving of constant string repair or no supplies if in SHTF scenario. Ive just ordered me a Cobra R9 system with your patented auto load design and im sure I'll have many hours of reliable fun and target bashing. Thanks for all your Videos, keep up the good work and credit to you for being such an awesome engineer!
Crossbow strings generally last 1-2000 shots if they’re made well as I understand… it’s recommended to change every two years regardless. I think repeating crossbows are different- that lower poundage and higher cycle rate of stretching probably suits a braided line better.
1-2000 shots? Wow, people whose string lasted only 1 shot must've been really pissed they got the short end of the stick then! /s
thats only if you shoot 200-300fps under 170ftp, as soon as you hit 380fps with 200lb limbs, you need to be an expert to get over 1000shots with an high quality string
This is huge news! Joerg is such an underrated inventor. You are the giant genius of our time!
I've been using dyneema for my compound bow for years everybody tells me I'm crazy thank you for validating that I am not crazy as I am using every precaution that you are using and one by adding one additional sleeve of dyneema to the center and then serving it into place with a stitch serving not just a regular serving and of course I always verify that I am not splitting any of the threads and I keep the count as clean as possible equal on both sides whenever the dyneema or the serving splits the dyneema. And yes originally I started with parachute string but it was just not quite strong enough to do the job
Hi barretharms.i just came across your comments about using dyneema cord for your compound bow,what thickness cord did u use and how did u install your peep sight on the string.would appreciate any help you can provide.cheers Rene,from Vic,Aus.
As always love your videos! My Mother was German and I have been to Germany Many times. Love the people, food,beer and your accent!
DD hammocks in the UK, sell's Amsteel/Dyneema by the metre,. about a £ per M
thin plastic coated garden wire is handy for splicing / pulling the string through for a bury,.
also see some tuts for making whoopie slings,. as they cover useful techniques. brummel knot/ bury.
Another useful video from a Genius! Jörg!! You are the one!! Thank you sooo much for your time and advice!! Stay healthy and protected!!
I kinda want to see how it works on a recurve bow. This had single handedly improved archery by a lot, imagine if your rifle broke or deformed heavily it's firing pin every 10-30 shots, good stuff Joerg!
great tip Joerg I am a paraglider pilot and for sure Dyneema it is a great solution very durable , you are every detail always
Great video Jörg!
As I own the fenris setup with the greyback bow... I ofc wonder if this is possible to make one as a bow string?
They attach to the bowlimb a bit differently I see, will you make a tutorial in some sort for compound bows as well?
wouldn't it be just the same process?
I am sure it works for bows too, but I would probably use the 2mm type. But for a regular bow, you probably need to thicken the middle part so the nocks will still hold on.
@@Slingshotchannel Yes, or as some suggested.. find a way to use it as a serving, like a sleeve on the current string?
@@Slingshotchannel Could you pull a regular bow string through a little section of this Dyneema cord over the middle serving?
It would protect the regular serving of the string, but woul be much easier the replace when worn, than a complete reserving of the bow string. Using your copper wire technic.
The string would of course become a little more thick though, but you could strech adequatly or eventualy use this option INSTEAD of serving the bow string?
I am not sure there is much use of it in bow since bows have much lower forces than crossbows. One thing i like is that it seems its easier to make dynema string than regular bow string.
Also, if you don't loop back through the loop (above where Joerg says some people do but I don't) it can pull back thru if not under tension, thus making the loop bigger & ruining the length (as it's quite slippy).
I had some problems with the eye serving of my bow recently and I am unsure how to repair that.
As a relatively new archer I would love to not worry about my string and it's maintenance.
So I will try this with my olympic recurve and see how well it works.
Brilliant!!
Someone get this guy a lifetime achievement award!
Joerg ,. when you bury the end,. if you taper the end of the string a few cm , by cutting a couple of strands, ...it's much easier to pull it through.
Thank you so much, and I really mean that, for this instructional video on the string. I have a spare string for my crossbow pistol but I can't seem to find it. The one I have on it is still good but I would like to make another just in case I can't find the spare string that I have. So again thank you so much for showing this it really is going to be a great help for my little crossbow pistol. You make cocking these things look so easy because I think you are a strong man and as I am 71 years old and muscle atrophy has kicked in, well cocking is not as easy anymore. So thanks again very very much for this video as it was most helpful in learning how to build a new string, thanks again have a great day and stay safe and keep your powder dry and your strings strung! And may God bless.
Dyneema is amazing in its hollow braid configuration for splices (like Joreg shows), but it is also widely used as a core for many ropes.
Many rope companies will use an Aramid outer sheath (like Technora) for abrasion resistance combined with a dyneema core for even more resilience.
Technora is another wonder material. Its like Kevlar, but on steroids. It has a much higher melting point and good abrasion resistance, so its great as a outer protective sheath and is almost as strong as SK-75 or 78. Definitely a good one to check out.
The Kanirope guys actually put a coating around each strand before it is woven, which makes it perfect for the task. Abrasion and sunlight is no problem for this rope.
I checked the prices of aramid rope& it’s really expensive & seems to be mostly for climbing gear
@@Man_fay_the_Bru doubt that aramid would be used for climbing because it doesn't really stretch and you need that quality in climbing rope to keep it from injuring you if you fall
I was recently looking around for material to make bow string for the bows I have.
And this video might have just offered the solution.
Thank you so much
Thanks for this video Joerg! I have been struggling for some time to thread through braided cord, and your DIY tools may just do the trick! My use for spliced cords is whoopie slings for suspending a hammock while camping; one end is spliced as you show with three or so pass throughs. But the other is only buried through a length of about 15-20cm once. This allows it to slip though when unloaded and the length to be adjusted. I got so frustrated with my attempts to splice I researched kumihimo, a Japanese braiding technique (lots of videos online). While I can achieve the same thing, it takes way longer. It does offer more opportunities tho. Thanks for all your great videos!
Check out tacblades RUclips channel on amsteel whoopies
Thanks Jöerg!! You bring the engineer eyes point of view but in a really attractive way. I love your work!!
Joerg, it has always been a pleasure watching your channel. I work in IT and catch myself when explaining something with the urge to say "Let me show you all its features" thanks to you 😂. I have been a fan for a long time. Furthermore, I don't have a crossbow or bow yet, but the problem I have is getting it past my wife 😏. But ever since I saw you showing your Legolas bows, I was hooked. I was thinking, I really hope he gets a patent, and makes millions, he truly deserves it. You have a passion for it, which I respect (I like to tinker too which I tend to do, but with much less success... ahem). Anyways, I wanted to express my appreciation and always look forward to seeing what you're doing next. When I do finally manage to finagle my way into getting a bow or crossbow, it's going to be GOGUN 😉. BTW, cool idea with the replacement string. I had no idea that's how it's done, video saved for future reference. I could easily apply it to other things too. It also looks strong and very neat without the knots sticking out. Keep up the good work, and I wish you continued success!
Ladys often in archery!
@@davidm.4670 Hmmm... great idea, I could use that angle😅
Wow, just amazing…made it a few times just to perfect it. now works great. even used the straw and copper wire method. your the man!!!!
I would love to see a comparison video with let's say the siege with the original string and the Dyneema, measuring how many shots it takes for each to break :D
Mondta hogy 450 lövés a dyneema, kicsit hosszú és unalmas videó lenne
Please never take this video down.
I'll propably need this in the future.
Why not download it then? I download every "how to" I think I might need to use latter. Mostly machining videos in my case, got quite a handy reference library now.
if you want to avoid a stress riser at the end of the bury ... cut out two strands every cm of the tail you bury to taper it down
Joerg, I am convinced! Since I have an Adder, this was my main frustration! I will try this for sure! You are a real problem solver!
Sixteen times stronger than steel!!!? And I was going to recommend aircraft cable. Wow!
I'm a newcomer in crossbows and slowly learning in this field, Your videos are very entertaining and a very learning experience! I hope you make Billons on your new Product!
About 15 years ago, I met a weaponsmith at Cornel University that had made a miniature crossbow (8 inches long w/ a 6 inch armature) that had a 500 pound draw. It needed a screw winch to arm it. It shot toothpick sized steel bolts, that could punch through a quarter inch piece of plywood like it was tissue paper. I bet he'd have loved the weapons you make!
I’d like to see that
Great video taught me something actually useful unlike most videos,thank you.
Your manufacturers gonna hate you for this 😁
gut überlegt , sehr gut gemacht und nett , es anderen leuten so anschaulich zu demonstrieren !
well thought out, very well done and nice to demonstrate it to other people so vividly
So how about testing it: shooting without maintenance until something goes wrong? Like 20 shots a day for example.
Thank you for the technique and material to make a virtual foreverbow string of any length.. You have helped archerty nemisis once again . You are an engineering genius.
no audio?
This kind of video is exactly what I'm talking about in the last one I wrote something, everything from start to the end. Perfect.
Amazing job.
Grats.
I bought the adder crossbow from your very 1st shipment, and it's awesome. Do you have plans to sell the dyneema replacement strings on your website in the future? I would absolutely buy some replacement strings.
easy enough to make your own ...
Joerg. You always invent. I love your English....accurate, fun and cute. 😊♥️
I dont know anything about archery, but i have a little engineering experiance. My question is what does a Dyneema bow string failure look like, and how does that compare to a traditional bow string? It seemed like the original bow string showed visible signs of wear and tear as it was reaching the end of its life. If the dyneema fails suddenly and catistrophically withiut visable warning signs, i could see that as a potential safety hazzard, even if it is a more durable string overall.
It starts to fray a bit and this gets worse. So you have a real good way to check on it. Since there is no middle serving, a little fraying is no problem for the integrity of the string. You have 12 strains and EACH one of them can hold the draw weight of a crossbow.
decades ago in collage archery we used kevlar strings that had sudden failure mode (did not even spoil flight of arrow on which string failed).
This was on fairly light (target) recurve bows and not a hazard.
Joerg, the serving needed is High powered fishing line,... its used on some Compound bow strings.
The recurve crossbow strings I see look like just a bunch of B-50 strands and a cloth serving.
But, if you use fishing string for a serving it is much stronger to ware and it protects the string.
As for your strings Dyneema I'd add bees wax for added strength.
Joerg~ Dyneema is a type of bow string Dynaflight D-97, BCY FORMULA 8125 and DYNEEMA '02 ARE ALL BOW STRING MATERIALS.
I'm thinking your Dyneema rope hack is like a Flemish string for Compounds.
Is it just me or is the audio muted?
Not just you.
Simply genius. Im going to use this on my selfbows too. No more endless hassle with serving. Thanks Joerg!!!
This is how engineering used to be, create something that lasts as long as possible.
But the archery industry knows that their biggest gain is from people buying strings and arrows again and again. So they have no incentive to fix this ever.
Thanks Joerg.
Danke. Du hast mir viel Verzweiflung und Geld gespart. Bei meiner Siege ist die Orginalsehne nach 20 Schuss defekt gewesen. Natürlich kein Ersatz dabei. Das wiederum hieß für mich Sachen Packen und nachhause. Danke dir 🎉
Amazing - another great use of friction. Do or could people make their own bowstrings too using this technique?
Real 550 cord is probably good enough for a normal bow, and a hell of a lot cheaper than dyneema. Don't just use any random "paracord", buy good stuff with an actual rating online or at a store that specializes in ropes and cordage. You're looking for cord that meets "Military Specification C-5040H". Use some inner strands from a waste piece to do the wrapping at the nocking point.
In the end Jörg destroyed his own business with replacement strings. But his value of being a honorable man has risen ultimately. Thank you Jörg, you are one of the greatest! ❤️
As we say in germany: Ehrenmann!
Dyneema need to sent him a gift basket for all of the extra 0,0001% revenue they now make by selling length of rope to the Bow community^^
@@alexs5814 Give him a distributorship?
i couldnt get audio for this one buddy
I already made for my modified 110 lb crossbow using 3 mm dyneema, fixing to buy 6 mm with same specs and build it for my big 175 lb bruin crossbow, I can't thank you enough for this
Is it just me or is there no sound on this video?
20 mins later and now there's sound... weird
Joergs done it again...another breakthrough... pure genius!!!!
You lose more than a millimetre on the bow compared to the nails because the circumference of the arch ends is much bigger. I use dowels , just as easy . For proper strength, feather that tail so theres no weak point, not important on an adder but on stronger arches it might be. Bit of trivia, people say they do something to the bitter end. That trailing rope that is buried is called the bitter end, like many things we say, it came from the navy in old days, like between the devil and the deep blue sea ...but the devil is a whole other story from ships not satan :)
Your timing on posting this is crazy. Got my first crossbow about a week ago and already figured out I'll be repairing the serving on the string every 30-50 shots. Can't wait to see what you've found.
This video is silent to me? No others are. Anyone else?
Me too
It's fixed
@@slpk thanks for telling me
Again and again. You just do it so well Joerg.
Why so low resolution of the video (360p max)?
youtube needs to (re)render the bigger resolutions, will take some time and the moxe pixel version will be here. It only happens to the "early viewers" ;)
Dyneema pricing is just about to go through the roof! Might be worth stockpiling while it's priced as is and to even resell later down the line.
I doubt the archery community will use that much ...
Ein echter Bastler und Handwerker, respekt wie du das alles angehst Jörg !!!
Joerg needs to start SELLING this strings in his store! I (and likely many others who are pressed on time) would gladly buy it instead of making it at home.
as an engineering student i am so jealous of your discovery! this string sounds very efficient
Am I the only one there's no audio for? Preroll ad had audio...
Seems to be fixed*
(I changed nothing)
Great and informative video. It's fantastic that you show easy to make tools from objects found around the home.
Joerg needs a statue somewhere for revolutionizing modern archery again and again :P
The trouble will be finding a material that is strong enough 😅

Am I the only one with no audio on this video?
Thank you Joerg, I appreciate you a lot. You have introduced to me a great new adventure and a hobby in the best manner possible. This dyneema tutorial is amazing and works great!
Hmm so no serving?
I would be quite nervous that it might tear and break the limbs or slash me to the eye... Have you done some further durability tests without the serving on hi-end compound crossbow?
Yay! I now know how to splice a hollow rope for an eyelet😁! Thanks, Joerg! I'm using this technique on my long bows, cross-bows, and bamboo short bows.
Hey Joerg, I think that something happened with the audio of the video
So instead of keeping it a secret and making money off a new miracle product Joerg just simply shows you how to do it and where to get it 😎 what a stud... one of my favorite people on earth thanx Joerg your the man.
Has anyone tried using Kevlar rope as a crossbow string? It should be stronger than Dyneema. A 3.5mm Kevlar rope can hold 800kg
It is kevlar. Dyneema is a trademark. You can even find cheaper non-branded UHMWPE
@@trollmcclure1884 Its not kevlar -kevlar is Dupont(company that polluted west virginia river with teflon making chemicals ) trademark for Poly p-phenylene terephthalamide.
While dyneema is trademark for ultra-high molecular weight polyethylene.
So its not the same .
@@zumbazumba1 indeed not the same thing. However my point is that you dont need Dyneema brand for ultra-high molecular weight polyethylene. It can be Spectra or just UHMWPE
3mm Dyneema offcuts rated 900kg that I had used for sails, tested to destruction exceeded 1000kg
@@louiscannell6274 It's actually a pretty bad result. It's a good custom that ropes and climbing equipment usually has to withstand at least 30% more than its rating before failing. It's probably your fault tho. Your test was not standardized. It failed in the knot or on the edge of a carabiner. You need at least a controlled setup like the bench used by HowNOT2.
