The new designs are amazing, and Joerg is without doubt a genius, but I'm thinking that we can actually hear how powerful the devices are by the time between firing and hitting the target. We obviously can't do that with any accuracy just from the sound, but I am sure we can get a pretty good idea. So getting to the point, it seemed to me that the first arrow firing catapult Joerg showed us was the most powerful. There is barely any time between release and impacting the target.
That 3 foot rubber band stretched out to his eye worries me! If you break the top rubber band, it could prove painful when it slaps you in the face! Maybe a small shield to keep that from happening would make me feel better?
Duggy Dugg wouldn’t that be great but, Joerg would make a fantastic enemy, he doesn’t need millions to build weapons, just a shed, saw, roll of strong elastic and a few 8x4 sheets of ply board 😉😊

Love it. Design fails and hurts finger. Jörg just goes "Ow!" and proceeds to examine the damages of the DEVICE, studies it for a brief moment and within a single shot, explains what happened and how to improve upon it. That's some next level engineering.
Not trying to olay off his engineering prowess. But to be fair, with as much experience as he has had with his plywood monstrosities, he has probably run into the same set of issues hundreds of times throughout the countless prototypes hes made.
To be honest, that first thing I thought, when I saw that design, was that it was a potential thumb pincher. Wasn't expecting it to happen on camera though lol
I can picture Joerg in the early days of the US space program, shooting astronuts into outer space with rubber bands and shouting let me show you its features.
I saw a video about a German gun that was designed to fire caseless ammunition, I think it was called the G11. The video was titled "Krout Space Magic". It's on the forgotten weapons TH-cam channel. My dad was stationed in Germany for several years and is where one of my sisters was born, I still get a chuckle out of how the world perceives German inventors... mainly because it's true.
Joerg is honestly such an inspiration to me as an engineer. Most youtubers would have stopped at the first folding-rubber-instant-legolas and kept the video at the same length but this guy goes above and beyond because he has the genius, talent and passion to do so. The last of which is incredibly infectious and makes me want to further my own projects with a similar level. Thank you for your amazing videos and wonderfully cheerful chuckle Joerg.
And after that you have to take it to steambow so you can sell me one the slingshot channel is becoming the shut up and take my money channel for me really fast.
Jeorg: I know what you're thinking: "Did he fire six shots or only five?" Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being this is a .folding-rubber-powered-sliding-instant-Legolas, the most powerful sling bow in the world, and would blow your head clean off, you've got to ask yourself one question: 'Do I feel lucky?' Well, do you, punk?
@@bonafidetom52 I would love to hear Jeorg say it. Someone needs to put his face over Eastwood's in that Dirty Harry clip. I'm sure Clint would not object.
The part at 14:27 deserves some more discussion. Without using pulleys or leverage of some kind, any slingshot's mechanical efficiency is limited by the ratio of the projectile mass to the sum of the projectile mass and one-third the mass of the rubber. One-third the mass of the cord used here is probably a decent amount of mass compared to an arrow, which gives you a hint as to how inefficient a slingbow becomes when shooting projectiles that are light for the draw weight. I think a relatively easy way to overcome this obstacle is to use a fast flight bowstring in place of the rubber cord. Then run each side of the bowstring through its own three fold purchase block and tackle with small-diameter, grooved nylon rollers to minimize rotational inertia, where each forward roller is fixed to the very front of the weapon, and each rear roller is attached to some short thick rubber bands with the other ends of the bands fixed to the weapon. This setup provides a 6:1 mechanical advantage, so while your power stroke might be 80-90 cm, the bands only have to stretch by 13-15 cm. The effective mass of the bands is then reduced, not by a factor of three, but by a factor of 108! And the fast flight string would be much lighter than the rubber cord. I could see a slingbow design like this launching arrows at well over 200 m/s. Imagine that level of power with rapid fire capability!
You are a great teacher joerg and very generous in sharing your time and energy for entertainment and hive knowledge. Wishing you and your loved ones the best. You are a natural 'mechanic'. My favourite kind.
I wish I had the cash to fork out for an Adder, I sure have lots of time on my hands. Good thing it's forever out of stock so I can't be tempted regardless.
Oh man, the slow motion at 14:00, the perfect arm allignment - right elbow draw to the left hand straight stretch. You truly are the most professional Bow and Arrow shooter. And look at the stability and straight arm formation while reloading, not a bit of slight misalignment even on slow motion. Perfect. You really are the best.

This is a great development in terms of moving the sling anchors away from the body to build more tension , and thus more power; and there is still the potential to move the anchors further ahead, by using a sliding system to that triangular base to extend it a couple feet further away to shoot, but contract it again to pack it after use. Nice going, keep up the good work Joerg.
I think you could reduce the length of the slingbow by adding a gear and rack system with two sliders (one for the arrow and one for the fork, so that as you draw the arrow back, the mounting point of the rubber is pushed forward by the same amount. This would let you keep the same draw length, but effectively halve the total uncocked length at the expense of some height. Always nice to see your videos! Keep it up!
Joerg, I actually built a very pretty sling bow similar to yours and even inlaid brass into the plywood made from laminated oak. Trouble is, I am a little 150 pound retired mathematician and 62 pounds is far more than I can draw with a release. I had to drop it to 20 pounds and make my own very long thin arrows to get it to fit this old man.
Maybe make the rubber coaxial w the arrow? Make the "carrier" a "T" w the tail toward the muzzle. The "T" slides in a longitudinal channel. The upper "T" arm carries the projectile, and the lower is attached to the rubber (or spring, or whatever power source). Use as many rubber bands as can fit. They can even be stacked - say, two payers of four bands each. More bands, more power. Maybe make it a lever action bullpup. The stock sits on your shoulder, with the magazine *behind* your head. Add a pistol grip far forward, and position the ~18" lever between the pistol grip and the stock. OK, your draw length w a simple lever is less than in the hand-drawn layout, but w/ coaxial power, adding more bands can achieve the same force in a more compact form factor.
Also, combine the lever action idea with the power-in-series idea, and it's pretty easy to imagine using the forward stroke for the lever cocking the first few bands, leaving the more powerful rearward stroke to pick up most of them. This could increase draw length for even more bands in series, and even more power.
I don't know if Joerg is going to see this, but i think that this is just amazing! Congratulations! This is the prototype transforming and having a lot of new iterations and each time making improvements. Now becoming something more polished and actually putting out new designs of a tool that was created thousands of years ago. I'm impressed.
Another brilliant invention from my favourite inventor and engineer! You've done it again Joerg 👍🙂. Question: Would it be possible to have a hinge on the barrel in front of the stock, so to fold it together and make it easier to transport?
Add a downward grip post (as you've done in the past) to the end of the far end of the slide / receiver to allow your awesome one handed draw power retention. This would require a long slot (length of draw) in the new fork feature to accommodate the new grip post, and the fork would need to be extended maybe 5 - 6 cm past the far end of the slide when relaxed. The fork slot would be closed / bridged at the far end for strength & stability.
Joseg you have such a tremendous engineering mind I just love watching your videos you are so much fun the best laugh on TH-cam thank you for The great videos from America
All the time, I asked myself what these stiff "bow arms" are for, if they do NOTHING functional in terms of building tension during the draw. But as always, out ingenious inventor found that too and eleminated all the unnecessary bulk, just to replace it with some "new features". :-) Great work!
@@Slingshotchannel compared to a regular bow I don't think it's more compact. But it is similar size and has the instant Legolas, that definitively makes a regular bow more bulky
@@Slingshotchannel You could also make the front part of the barrel / sled foldable by just cutting it und attaching a hinge on one side and a locking mechanism on the other side, couldnt you? That would make it a little bit more compact for transport :)
2 sliding diagonal braces. Much like a tilt-out window pane or casement hinge, perhaps slightly bulkier but could be tweeked. Thank You for the time you take to do all this and inspire other people. So cool your design is. .. ¡Tschuss!
Im just so intriiged about this. And as engineer myself I just love this mans attitude and aproach to fysics and really just matenmathics so theoretical and he makes then really easy to dissect and have the learning prosess that he is having. Thank you for this!
@@lkfh1 yeah a magazine with steel balls sure could hold more shots huh. but harder to go pick up your steel balls out of the home invaders than some arrows xD
Thanks Joerg! Another awesome video to brighten the day :) would be awesome to have a workshop tour video to see behind the scenes of how you produce all these amazing creations. Sitting here in my shed in lockdown making mini bow and arrow out of hazel we coppiced for my 3 year old to try in the garden. miles away from your masterpieces but enjoying it non the less.
What gets me is that when he releases a video one would think: oh it's just another instant legolas video... but he never fails to show something new or improvements or challenges he had to face with the project. Truly interesting and I thoroughly enjoy it!
Joerge i hope you are getting compensated by any company using your ideas.Actially they would be fools not to have you on their payroll the ideas you have seem endless
This has to be the best homemade weapon I've seen or heard of, literally has everthing, it's safe, it's strong, can be made with relative cheap materials, seems accurate and its always ready to be fired.
This is an amazing design! I would love to see this made with a no-compromise approach to the materials and manufacturing methods to bring out its full potential.
Great stuff! Could the handle be mounted to be moveable and extend the base slider? That way you could slide, lock then slide the handle back and get and extra length draw without the use of rollers. It would also allow 'smaller' people to get the full draw of the slingshot...?
Since you fire it sideways, you could attach a sight in a reasonable place and easily also attach one of your monster 40 round magazines coming out horizontally. High capacity Tactical sling bow with precision aiming.
it's actually really cool that you mentioned that about drawing it out farther because back in history (and i could be wrong about this) i forget exactly what part of Asia but they would make guides for arrows out of bamboo allowing them to overdraw their bows making them more powerful
Yep. That's what I was getting at. A few refinements yet to come, no doubt. I reckon it could be made into basically a TUBE. Like a scuba speargun. Since the rubber attachment points need to stand out a bit, how about some little "limbs" that pivot out only when the full draw tension is applied? Also the LENGTH could be telescoped down for storage. Thanks for sharing your creative process Georg!
Lovely to see one of your old slingshots featured again, been subscribed for many years after getting my first wrist rocket. You have come so far Joerg! Very excited to see what comes next as always! Edit: This design reminds me of another channel's bow creation, be sure to look up Primitive Pathway's folding recurve bow if you have not already!! Edit 2: The last iteration of your design in todays video really reminds me of old-school slingshots that had forward-extensions on the forks, I wonder what else can be taken from slingshots for this creation!
You could possibly make a locking system for the slide when it’s fully cocked then use the notches connected to the bands on the butt of the “toy” to hit a button or little switch that releases the slide from a locked position after it is shot. Just a thought! Been a fan for 7 years! This my first time commenting
This thing is dangerously close to being a repeating speargun for divers. The strings connected to the spears would be a fun engineering problem to solve. Draw Assist, larger magazine (it's on the outside now), add the forehandle. Then maybe you need a trigger for one handed firing while diving. Fascinating.
love the forward arm final product! it was genius! solved several problems of the first one. Think of this, had the first one not failed, you may still be using one with multiple limitations. Sometimes the failure is what creates the success!
I'd love to see a verison of this converted into a walking stick or cane. Not in any way that would conceal it's nature, but in a way you could use it as a brace when you're not using it as a slingbow.. Would be very steampunk-esque, but I could also see a full-length walking stick version being great for hiking trips or hunting!
Joerg, you are clearly the most tragically unacknowledged genius on the planet. Thanks for the videos. Can you make a video on your best methods of attaching rubber to all the various parts that make your inventions work?
Hmmm... Could you make it even stronger with a device for investing some energy while pushing the magazine forward, like you have done for instant Legolas?
Well done, you have made a very effective repeating sling bow, and there is no way that any enemy soldier could attack you head on, without getting a few arrows in them!!

Next up, the instant legolas briefcase
@@Slingshotchannel would be cool to see, but sounds difficult.
@@Slingshotchannel what if rather than hinged it was socketed or threaded like a gun? Would that make it easier to maintain barrel precision?
@@Slingshotchannel what about a draw lock via trigger on pistol grip? multiple holes for different draw lengths?
Add a downward grip post (as you've done in the past) to the end of the far end of the slide / receiver to allow your awesome one handed draw power retention. This would require a long slot (length of draw) in the new fork feature to accommodate the new grip post, and the fork would need to be extended maybe 5 - 6 cm past the far end of the slide when relaxed. The fork slot would be closed / bridged at the far end for strength & stability.
Joseg you have such a tremendous engineering mind I just love watching your videos you are so much fun the best laugh on TH-cam thank you for The great videos from America
A build video for this would be awesome. As well as some measurements to its actual power. This looks amazing! Great job :)
Wow. Coconut/gelatin/precision test for the slingbow lance pls.
Yes that would be awesome.
All the time, I asked myself what these stiff "bow arms" are for, if they do NOTHING functional in terms of building tension during the draw. But as always, out ingenious inventor found that too and eleminated all the unnecessary bulk, just to replace it with some "new features". :-) Great work!
slingbows have one big advantage, they are small..... lets make it huge
Yes, I think Joerg missed with this being not compact.
Compared to a regular bow, it still IS more compact.
@@Slingshotchannel compared to a regular bow I don't think it's more compact. But it is similar size and has the instant Legolas, that definitively makes a regular bow more bulky
@@Glimmlampe1982 it is more compact though. Just look at it, don't think just look and see
@@Slingshotchannel You could also make the front part of the barrel / sled foldable by just cutting it und attaching a hinge on one side and a locking mechanism on the other side, couldnt you? That would make it a little bit more compact for transport :)
Just great, never ending fun, thank you for taking the time to share the videos, please keep them coming.
You are amazing Joerg! an amazing human being.
I wish you my very best.
2 sliding diagonal braces. Much like a tilt-out window pane or casement hinge, perhaps slightly bulkier but could be tweeked. Thank You for the time you take to do all this and inspire other people. So cool your design is. .. ¡Tschuss!
hi JoergSprave can you make a semi auto beer cap gun?
lol i'm glad you broke it down with a relatable analogy about using oxen to tow things.
Wonderful. I would like to buy the plans and make one myself.
me too

Im just so intriiged about this. And as engineer myself I just love this mans attitude and aproach to fysics and really just matenmathics so theoretical and he makes then really easy to dissect and have the learning prosess that he is having. Thank you for this!
Zombie Apocalypse: Starts
People's when they see Zombies: Please, someone help me, help !!!
Joerg: HELLO AND WELCOME TO THE SLINGSHOT CHANNEL
I would just suicide ...
The design of the second one really reminds me of the older projects he does and it brings back so much nostalgia
"I could make the pre-stretch out to here." Do it, Jörg.
And use your chronograph and ballistic gelatin test :)
Do it!!!
Imagine a version with steel balls 😂😂 u won’t ever need a gun haha
@@lkfh1 yeah a magazine with steel balls sure could hold more shots huh. but harder to go pick up your steel balls out of the home invaders than some arrows xD
Wow a vast improvement on an old design, and then an improvement on a design shown right in the video!
"62 pounds is very significant, so its not easy to pull back" * he says while clearly not struggling*
Thanks Joerg! Another awesome video to brighten the day :) would be awesome to have a workshop tour video to see behind the scenes of how you produce all these amazing creations. Sitting here in my shed in lockdown making mini bow and arrow out of hazel we coppiced for my 3 year old to try in the garden. miles away from your masterpieces but enjoying it non the less.
From Brazilian. This is realy beatiful engenering! Congratulations.
Wow I really like the way your mind works and that last design is awesome!
火薬を使わない連射武器ってなんかロマンありますよね！
What gets me is that when he releases a video one would think: oh it's just another instant legolas video... but he never fails to show something new or improvements or challenges he had to face with the project. Truly interesting and I thoroughly enjoy it!
You could maybe move that front handle back a bit then you wouldn't have to draw back so far from it.
Not good idea. Then the anchor point of the rubber bands is too far to the front and the draw is hard to control.
@@Slingshotchannel What about moving the back handle forward and making it a real pistol grip, trigger and all?
I hope you know much you are loved, Joerg. You’re the man!
Joerge i hope you are getting compensated by any company using your ideas.Actially they would be fools not to have you on their payroll the ideas you have seem endless
He is on our payroll.
@@audunms4780You are a wise man im a big fan of Joerg I wish you guys much success
I love seeing the difference in prototypes and watching your progression. It's classic Joerg!
Well i have one more idea, how about making an instant legolas slingbow capable of shooting steelballs?
He already did that. Instant rufus
You started since when I was 8years old , now Iam 19 . What a legend , you earn my respect
*Joergsparve: makes a slingbow*
sees the thumbnail "assault slingbow"
Snowflake authorities: *TRIGGERED*
This has to be the best homemade weapon I've seen or heard of, literally has everthing, it's safe, it's strong, can be made with relative cheap materials, seems accurate and its always ready to be fired.
This is an amazing design! I would love to see this made with a no-compromise approach to the materials and manufacturing methods to bring out its full potential.
Great stuff! Could the handle be mounted to be moveable and extend the base slider? That way you could slide, lock then slide the handle back and get and extra length draw without the use of rollers. It would also allow 'smaller' people to get the full draw of the slingshot...?
Man, I hope your feeling better after those journalists harassed you, keep up the good work!
Since you fire it sideways, you could attach a sight in a reasonable place and easily also attach one of your monster 40 round magazines coming out horizontally. High capacity Tactical sling bow with precision aiming.
it's actually really cool that you mentioned that about drawing it out farther because back in history (and i could be wrong about this) i forget exactly what part of Asia but they would make guides for arrows out of bamboo allowing them to overdraw their bows making them more powerful
This design is a nice throwback to your record force shot & the vs. Pistol videos from a few years ago.
Yep. That's what I was getting at. A few refinements yet to come, no doubt. I reckon it could be made into basically a TUBE. Like a scuba speargun. Since the rubber attachment points need to stand out a bit, how about some little "limbs" that pivot out only when the full draw tension is applied? Also the LENGTH could be telescoped down for storage.
Thanks for sharing your creative process Georg!
DOUBLE FEATURE!!!
Joerg even landed on a very similar idea that popped into my head for the first inquiry intro so I get to see it come alive yay!!
nice to see you've got us covered when it comes to supplying makeshift lethal weapons for the impending class struggle
Lovely to see one of your old slingshots featured again, been subscribed for many years after getting my first wrist rocket. You have come so far Joerg! Very excited to see what comes next as always!
Edit: This design reminds me of another channel's bow creation, be sure to look up Primitive Pathway's folding recurve bow if you have not already!!
Edit 2: The last iteration of your design in todays video really reminds me of old-school slingshots that had forward-extensions on the forks, I wonder what else can be taken from slingshots for this creation!
The clicking sound every time it reloads is pretty satisfying.
You could possibly make a locking system for the slide when it’s fully cocked then use the notches connected to the bands on the butt of the “toy” to hit a button or little switch that releases the slide from a locked position after it is shot. Just a thought! Been a fan for 7 years! This my first time commenting
This thing is dangerously close to being a repeating speargun for divers. The strings connected to the spears would be a fun engineering problem to solve. Draw Assist, larger magazine (it's on the outside now), add the forehandle. Then maybe you need a trigger for one handed firing while diving. Fascinating.
love the forward arm final product! it was genius! solved several problems of the first one. Think of this, had the first one not failed, you may still be using one with multiple limitations. Sometimes the failure is what creates the success!
I'd love to see a verison of this converted into a walking stick or cane. Not in any way that would conceal it's nature, but in a way you could use it as a brace when you're not using it as a slingbow.. Would be very steampunk-esque, but I could also see a full-length walking stick version being great for hiking trips or hunting!
Thank you! I listen to the sound and I can really hear the power of some of your stronger inventions! May be your mic's.
Would be awesome if you could make plans for this! Cool quarantine project!
Joerg, you are clearly the most tragically unacknowledged genius on the planet. Thanks for the videos. Can you make a video on your best methods of attaching rubber to all the various parts that make your inventions work?
Hmmm... Could you make it even stronger with a device for investing some energy while pushing the magazine forward, like you have done for instant Legolas?
This man is an inspiration, a solid background in physics always helps in designing an efficient tool. Awesome!
I love all the different versions of those builds
Most cheerful channel on the planet bar none. Amazing person
Well done, you have made a very effective repeating sling bow, and there is no way that any enemy soldier could attack you head on, without getting a few arrows in them!!
just watched the pyrocynical video about the msm its pretty old and im really happy your still here cuz im really REALLY intrested in your channel so you got a new sub!
