[@jmp814]

I recall the viewer recommending this fibre to reinforce already bought strings that Joerg was using. Naturally Joerg thought, why reinforce an inferior product with it when I just use it 100%. Well done both viewer & Joerg. Thanks to Joerg's instruction, industrious viewers can now apply this material & knowledge to produce & sell a range of the latest high strength quality completed bow strings, for those who would rather pay someone to do it, creating a new wave of business during bad times. Thankyou Joerg.

[@U.S.MachineMike]

Joerg is a blessing for all slingshot and crossbow hobbyists. He doesn’t do this so much for profit but to freely inform others to better enjoy the hobby he loves so much.

[@Bacteriophagebs]

I found that putting super glue on the windings in the middle of the string extends their life, but it's still just more maintenance. Given the advancements in materials, it's almost criminal that no company has tried this already. Joerg proves he's an archery genius once again!

[@ihaveaplan.ijustneedmoney.9777]

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.

[@severpop8699]

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.

[@ile84]

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!

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.

[@Man_fay_the_Bru]

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

[@iJacker]

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.

[@LordDragox412]

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

[@flyfin108]

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

[@barretharms655]

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

[@alexandermartinez732]

This is huge news! Joerg is such an underrated inventor. You are the giant genius of our time!

[@derandiheissst]

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

[@Pystro]

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.

[@Caram0n]

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).

[@IAA015]

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?

[@ForestRaptor]

wouldn't it be just the same process?

[@Slingshotchannel]

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.

[@IAA015]

@@Slingshotchannel Yes, or as some suggested.. find a way to use it as a serving, like a sleeve on the current string?

[@Vildgase]

@@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?

[@majstor76]

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.

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.

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!

[@7kyro]

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.

[@Slingshotchannel]

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]

I checked the prices of aramid rope& it’s really expensive & seems to be mostly for climbing gear

[@luvmechanix]

​@@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

[@LETME-kl9jg]

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.

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.

[@helenavandewater3846]

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!

[@MrTimmmers]

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 :)

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!

[@Man_fay_the_Bru]

I’d like to see that

[@IvicaSumerianivyn1964]

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

[@Kakmnesu]

no audio?

[@nathanelliot1596]

Simply genius. Im going to use this on my selfbows too. No more endless hassle with serving. Thanks Joerg!!!

[@oOReboOo]

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.

[@davidm.4670]

I doubt the archery community will use that much ...

[@vacuumelite2065]

Joerg. You always invent. I love your English....accurate, fun and cute. 😊♥️

[@kendallmoreira4028]

Hey Joerg, I think that something happened with the audio of the video

[@JamesKing2understandinglife]

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.

[@tannerarmstrong1496]

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.

[@Slingshotchannel]

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.

[@davidm.4670]

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.

[@Tijl96]

as an engineering student i am so jealous of your discovery! this string sounds very efficient

[@benscott19841]

Am I the only one with no audio on this video?

[@DM-lf9yy]

I just made my first string for my AR-6, i did it by hand, so no nails in a piece of tinder and it turned out pretty good for the first try. One of the eyelets was a little bigger then i hoped, but i compensate that on my second eyelet. I'm pretty happy with the result!

[@undrachvrsage]

Am I the only one there's no audio for? Preroll ad had audio...

[@undrachvrsage]

Seems to be fixed* (I changed nothing)

[@MythicMagus]

Whoever suggested Joerg try out Dyneema in the first place should be quite pleased. I think you helped our man here find a new favorite material.

[@vvk]

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.

[@dennislock3415]

Great video taught me something actually useful unlike most videos,thank you.

Why so low resolution of the video (360p max)?

[@jimjonjimjonjon]

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" ;)

[@tummy_fritters]

This is a great idea. One thing I would mention is that not all bows/crossbows are built to absorb the shock of a Dyneema string. Materials like Dacron have a little give to them. This means less energy transfer to the bolt/arrow, but less shock to the bow/hand (less of an issue in crossbows). Dyneema will also wear on the knocks faster than Dacron. If your limb tips are pure fiberglass with no reinforcement--either replaceable limb caps on crossbows or extra layers of material on recurves/longbows--a Dyneema string will eat through the knocks and ruin the bow.

Joerg needs a statue somewhere for revolutionizing modern archery again and again :P

The trouble will be finding a material that is strong enough 😅

Joerg I have always said you have genius in you man ! You have some of the fastest idea to concept to prototype to we have a container ! Let me show you it's features hahaha. I only wish you received your proper credit for all of your collaborations with other people and companies and you could benefit. You are the architect of archery semi-auto fire and machine bolt autofire. Thank you for that Joerg you have helped many of us develop our (non firearms defence) I will always be grateful to you for that !! I literally sleep better lol.

[@gravitomagneticpower]

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?

[@gilnemesis3547]

Hi Joerg, my uncle show me how to splice Steel cables a few years ago on Big cranes but it wasn't so delicate and needed very strong hands like yours, of course it makes me laughing a little bit due to strenght differences but the purpose is the same and the Best, thanks.👍💪💪💪

[@DubulDire]

Has anyone tried using Kevlar rope as a crossbow string? It should be stronger than Dyneema. A 3.5mm Kevlar rope can hold 800kg

[@trollmcclure1884]

It is kevlar. Dyneema is a trademark. You can even find cheaper non-branded UHMWPE

[@zumbazumba1]

@@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 .

[@trollmcclure1884]

@@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]

3mm Dyneema offcuts rated 900kg that I had used for sails, tested to destruction exceeded 1000kg

[@trollmcclure1884]

@@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.

[@JasonSmith-pc6kr]

Thank you for the info!! I recently 3d printed the Miniadder v2 and Adderini, and was surprised how fast the string wore out. I will defiantly try this.
