This video is aimed at slingshot enthusiasts only!
The whole community always wondered why and how tapered bands are faster and more powerful. Lots of theories and guesses, but no data.
This changed when Destin came to Germany, with his great professional grade super high speed cam in tow!
Finally, at last, reliable data.
You MUST subscribe to Destin. Destin's channel can be found at

Anyway, this video demystifies tapered bands. The hi speed video allows accurate acceleration graphs, and side by side comparisons.
Dan, aka ZDP189, has much more calculations on his blog
( tinyurl.com/blqwmvh ), I recommend reading it!
For those of you who want to make your own slingshot, I have written and published a pdf manual, plus a band size calculator. Here:

Good luck!
I never thought I'd see a video featuring both Destin and Jörg :D
great video joerg !!! thanks for taking the time to make it - john
@kumquatsta Just download my band manual from the link in the text description.
@sohy3010 I use a Casablanca turnkey editing system.
I feel like you were way ahead of most people with all of this. Been watching your channel for a very long time. I've learned a lot from you. Thanks 👍 😊
Excellent vid. I'm just getting into slingshots this week in fact. Your stuff has been invaluable. And entertaining :)
Tremendous video guys! It answers a lot of questions that have built up over the years. Not only clearing up the differences in tapering versus non tapering but the camera showed something else quite clearly that has been debated for years. That is("when does the ball leave the pouch"?)/ Many have thought that the ball leaves before getting to the fork opening-camera clearly shows pouch and ball together till right at throat opening-Excellent job Guys!
Hooray for Joerg! Congratulation to you for this honor. You have certainly earned it. I am proud to be a long-time fan and glad to see this day. Good on you, Joerg! Leaving this post here as unable to post on The Sling-shot Channel for some error of sorts. --- for those wondering what this is about, Joerg is now a 'partner'.
@mrrsmurf Yes, I simply measured it on my 50 inch Plasma screen.
@zacharylisle These bands are nowhere near the top bands we use, those are target bands for Tobias (and me, when my hand is OK again).
I think the explanation is actually behind the weight of the rubber itself. The rubber near the fork needs to also move the rest of the rubber, while the rubber near the pouch needs only move the pouch. Thus, it is normal that the rubber near the fork needs to be stronger/thicker in order to contract at the same speed. Rubber is a relatively heavy material so this obviously matters. This is why tapered bands give more performance. :-)
@kallenmaurer Healing OK. Slingshot tournament coming up next week, gotta be fit by then.
Another well thought out, well presented video. Well done and thank you.
I wish you include the Handheld Slingshot Ballista in the studies. That's one of my favorite in your collection.
@LordRobere That would mean that the outside temperature and the release style (how long you aim before you shoot) would also have to be entered. Plus I would have to do millions of chrony tests.
@carambatsr Why don't you download my band manual from the link in the text description? It's free.
Most excellent! Do you buy the bands tapered or do you trim them yourself? If you cut them yourself, then how do you do it evenly and consistently? Latex isn't difficult to cut, but it does want to stretch and creep while you are cutting it.
I think you are a very creative guy and can see you enjoy doing what you are doing. Do you also have a tutorial about how to attach the thera-band and what to pay attention to when designing your own slingshot? You know...for savety reasons?
@vv2304 Tapered bands for the cannon would be expensive and also hard to do (the bands are long). Instead of rollers, we can simply increase the barrel length, which may happen.
280 likes and not a SINGLE dislike. Thats gotta be some kind of record! Great video JoergSprave!
@LordRobere These dimensions are from experience.
@LucianLycan1313 Maybe, when I have perfectionized it.
I think the tapered bands works like recurve bows in archery...it is a very informative video again with the slow motion captures :)
@i4l3x6 Ja, und auch bei Abenteuer Leben (Kabel 1).
Great video. It makes sense since tapered bands have less mass at the pouch and should be able to accelerate faster. It would be interesting to see how much weigh you've reduced by tapering and do some math. A ratio of band length to weight would definately be better with tapered bands.
Thanks alot Destin! This channel and joeandbuzz!
@Deepsand101 I have a website, but I don't sell anything. This is just a hobby.
Joerg, one thing I've meant to ask for some time: How did you arrive at the figures for band width in your calculator? How did you determine the band width for particular weights of the shot? I can understand length, but not how you determined both fork width and pouch width. I must admit, I do follow your guidelines, but I wonder how they originated and if I should even bother to experiment with them.
Excellent video big man. Loving the technology
@vulcanus30 The amount of rubber is the same, it is just cut differently.
Wirklich sehr interessant , ...vielen Dank für's Posten !
@JoergSprave , These videos are spectacular! Before this video, I was wondering "Why even bother tapering the bands...?" Love your channel and *especially* the Zombie Hammer Slingshot. Thanks a million! -G
I've gotta say, I love your accent. It's kind of funny to hear you talk, not that you pronounce anything wrong, but your accent is really cool and you seem like a great person. I hope that the rest of Germany is as good of people as you are.
Where do you get your bands? And do they ship to the us? Also, do they come pre-cut. What is the best kind?
@spikwizflo Ha! Good one.
i thought of something wile watching this video. you know how rifles are very accurate by spinning the projectile, well im wondering if there would be some way to get the projectile spinning from a slingshot... maybe a slingshot rifle with a rotating fork or something. like you load it like your other slingshot rifles but after its loaded you rotate the fork around a few times then when its released the bands rotate to line up with the forks making the projectile rotate and maybe more accurate.
@pyrophiloffthapill Just download my manual.
hey, think you could do a video of slingshots vs armor? (like chainmail etc)
@JoergSprave Will there be footage from the competition?
@broLAXgoalie12 The accel phase is still a lot longer. And the end speed is faster. The only thing that comes clear is that pulleys work, since they eliminate the dead play.
Very nice. I love a good graph.
that was very interesting, nice video!
@JoergSprave machst du mechanische sachen wobei dir deine beruflichen fähigkeiten beim schleudern machen hilft ??
are you going to record anything at the tournament?
Very interesting, informative, and very cool.
Great video Joerg thanks for sharing very interesting
Any chance you have this when the ammo is run through a chrony? Thanks Blazin'Blades
wow. tapered. great vid as usual joerg.
Is there a recommended taper? What is the width difference over what length?
Joerge, how did you calculate the m/s for the two vidoes?
Some guy had a video testing Thera Band Gold vs natural latex and according to his tests natural latex is faster? I wanted to get your opinion, because I always thought Thera Band Gold was better. I don't know if he was just too weak or what?
Oh, I forgot to ask one last question: From your calculator, should not one be able to determine both meters per second and Joules also?
does this mean that you can make a sling short with very strong rubber near the fork and then connect to it a weaker rubber near the pouch? for example theraband black near the fork and then theraband gold near the pouch? i think that could be a really interesting experiment
Hey joerge, hows the hand doing?
@JoergSprave do you have a regular job or is it your full time hobby ?
@PimpinPoptart06 I know the draw length, and measured the difference between the frames on my Plasma.
@JoergSprave Since you are the most experienced shooter I know and I trust your inventive and smart mind, I am comfortable with your figures and how you arrived at them. Now the only thing I wonder about is if multiple bands would outperform a single band if the total width of the multiple bands collectively match the width of the single band. Using your ratio to measure the pouch and fork difference, multiple bands with very narrow tapered pouch widths might be faster, if strong enough?
@unexceptionalrebel Don't forget we are talking milliseconds. Hard to squeeze right on time.
what program do you use to edit you videos? thanks
I'm just spitballing, but doesn't this kind of refute your butterfly method since the acceleration on the larger band set ends much earlier in the ball's trajectory?
hey did you make the sling shot at 3:51 if not where can i get me one?
Is there a way to remove the ripples? Maybe if the forks become wider at the same moment that the ripples start it could provide more tension and remove the ripples. If there was a handle grip that you could squeeze at the exact right moment that would somehow widen the forks.
@TheBoyFromNorfolk No, but from all of the rubber that is available, only Thera Band (gymnastics bands) and natural gum rubber (industrial) work really well. All other types are kind of lame in comparison.
@MrHappyStacker No, but my niece lives with us.
personally I think your English is terrific, very impressive, and your sling shots are all revelations, can you reveal some sources of the different types of bands that you use! where we can get them, and tell us, how we can get your blueprints for your various types of projects
@JoergSprave Is your Neice into catapults?
@kleinesmaenchen Nein, ich habe einen reinen Bürojob.
whats the highest velocity you have achieved with a slingshot?
hello could u plase make more video they r great
amazing! thank you
Sorry if this is the wrong place to say this, but do you patent any of your slingshots?
Thanks for doing this. Looks like tapered bands rule.
@suldubulduu No. I shoot steel, and hard, not soft.
I come at this as a chemist. I wonder what the chemical differences in the rubber are, and how they contribute? Is there specialist designed slingshot rubber?
Very informative.. Thank you
I'm not a slingshot enthusiast, but I still found this interesting.
@averyaccordion yes but even be for the mini ball was invented rifling and the rotation on the round ball improved accuracy
@hellwatcher999 Actually, Tobias and Wladimir will both be there, to fantastic shooters. I am hoping for a third place.
@JoergSprave im sure you will have no problem taking first even if it's not healed completely
I swear there will have vids of the slingshot tournament
Schönes Vid, solche Studien sind sehr willkommen. Der hat wirklich ne gute Kamera ;)
I like the first 2 slingshots you had
@blouistu101 Probably.
do you purchase your bands tapered or cut them yourself?
@ZDP189HK Yea yea, Joerg said "ZDK-189" and i remember reading your blog on SlingshotForum about the bands and such.
This was really cool :) thank you
@12Chinyere Says the man who doesn't have a single video made by himself. Most of my viewers have no problem understanding my English.
Thanks for taking your time to help your fans. Here in America most people try to make a buck off everything ! But not you.
3:47 This is really cool.
great vid mate.
Thanks fot the knowledge
@unexceptionalrebel i think the only way to get rid of the ripples would be to remove any slack from the bands. that way they are always in tension, even when youre not pulling on them.
it looks like the ripples begin to occur once the band curvature becomes concave. The pouch moves forward of the rubber, and the ripples take hold.
i would like to make a sling shot how do i truly make shure to prevent sling shot back fire when releasing to fire?
Great vid very educational 12chinyere is wrong your accent is awome! By the way i heard taperd bands break and snap faster than normal flatbands, is this true?
Thx for this interesting video!
Guys, please remember what we learned in primary school! Acceleration is made by force. Stronger rubber makes bigger acceleration. If you compare parallel and tapered bands wit same pulling force, then you will get very similar speeds.
Wrong. The maximum retraction speed of tapered bands is much higher and also the efficiency increases, so at the same draw weight and using the same projectiles, tapered bands WILL get you more speed. The disadvantage is that the bands tear earlier.
Could youprovide us exact data please? A simple xls table with 2 columns: the force of the parallel and tapered band at 10, 20, 30....100% of draw length? Easy test, only a fishers' scale is required.
sehr schöne aufnahmen!!!
thats interesting. i have never made a slingshot, but i have a trumark. i have bought 2 different types of bands, one was thicker and looked stronger, and the other was tapered. with my tapered one(much thinner), i could shoot through like 2 cans full of water, where my thick bands can go through a single side of 1 can(yeah its a weenie little slingshot that ive got.)
Now see, this should have been the "Smarter Everyday" episode! LOL
