Just imagine that you're a Paparazzi, hiding in the bushes behind Jörg's house, trying to get the perfect picture - and the last thing you hear is: "ups... to high..." ;-)
I mean it would be deadly to get hit by it if it hits in the right spot but at the end of the day it's just a stationary bow. A makeshift shotgun would be better for home defense
As somebody else mentioned, have a look at the game "Kenshi" they did exactly that for base defense. One of the later upgrades for the mounted crossbows is a repeating design for high fire rate.
@@michaelpettersson4919 when was the time you see a completely well built and fortified base in mad max ? Most of mad max is chases on vehicles and not much room for fixed defenses to show up
"That would be completely deadly for my enemies... HAHAHAHAHA!" The combination of clever engineering and enthusiasm makes this channel a real treasure.
Yeah, well if Germany had a bunch of inventive and creative genius' like Jörg the outcome of the first and second world war might well of been different...if his leaders had the sense to develop his ideas.
6:40 The Dark Souls-esque music combined with Joerg’s laugh as he shoots a medieval contraption is like the pure distilled essence of everything I love about this channel
Awesome as usual. To my mind there is nothing in this build that a skilled engineer in medieval times couldn't have built using available materials. Obviously not modern plywood like that, but either flat planed solid wood or medieval plywood as used in viking shields.
Agreed as the ancient world was more advanced than we know as the Greeks built a repeating crossbow. Also during even in the 15th to 18th century they could have done even better and even used the Garedoni (apologies as I don't remember the correct spelling ) air powered system and built a successful Van Helsing style repeating crossbow
Awesome! For your next project, Joerg, you should make a wall-defense sitting crossbow, operated like a rowing machine, where the seated user can use his or her whole body to draw a real heavy load - then aim and release. :D
perfectly explained, not powerful, fast, but ineffective… hahaa, and you even built it better than the movie version with more than 2 times more rounds. thanks for this great video Jörg!
*How different* medieval warfare would have been if this actually existed during it's period? Whilst as deadly a crossbow and its bolt was, they took forever to load and shoot. Hence why longbows were more effective.
When I saw the clip from the movie the first time I actually thought: Earlier in films like van Helsing for example they had completely undfunctional repeating crossbows. But now that Joerg actually builds these things they tend to look a lot more practical in the movies as well
If I remember right, the one in van helsing is gas operated, so you technically could build something similar as a functional weapon, it wouldn't have the glaring energy problem like this one. Launching the bolt could be pneumatic too instead of having crossbow arms, so the only mechanical problem you'd have to work out is loading the bolt, which could be done as a sliding trapdoor, slide it open, push the bolt in, slide it back, the whole thing could be done with a single piston just fine. If that isn't close enough to the original design, we already saw a pneumatic crossbow here, so a pneumatic fenris system should be possible. One more thing to keep in mind is that in this particular case it wouldn't even have to be all that powerful, it's enough to just be able to stick the dart in a vampire and silver poisoning will do the rest.
Maybe take inspiration from a Stryker shotgun. A fixed drum magazine where the trigger fires and revolves the next round into position. the width of a bolt is leagues smaller than a 12 gauge shell so the ratio of movement needed is fractioned, I’d imagine the trigger pull will actually feel progressive. Put in different gears like on a (bicycle/revolver) and the same distance the trigger travels will give more or less depending on which “gear” you choose, making a single shot into a variable burst. I’m riffing but I think better explained with more thought in simplicity and overall weight it could be as easy as a couple of Co2 cartridges from an air soft gun and you have a viable product
Note to self: Do NOT try to invade Joerg's castle. I will not end well...for me. Joerg: "Hah Hah Hah! No it will not. Now let me show you my castle's features."
... And they would be so terrified by the sheer destruction that a certain Shogun would order flowers be planted upon the field of massacre and the infernal device destroyed. >):^I

He really is though. He has come up with a tremendous amount of original content over many many years, and with no signs of slowing down either. He honestly might be my favorite youtuber of all time overall.
This reminds me of the Chinese Zhuge Nu or for my Civ gamer bros the Chu Ko Nu. Basically the Chinese made repeating crossbow in the Three Kingdom Era, legend has it that it was invented by the legendary Strategist and Inventor Zhuge Liang. And you can buy one in Alibaba in China or in the northern Chinese cities gift shop as those were where Three Kingdom themed Tourist sites based. While they are not as powerful as a traditional crossbow, they are easy to use , has fast fire rate and can be fired by even Palace Female Attendants.
In reality, like this one Jeorg built here, the zhuge-nu would've been very weak, & due to technologies available back in those days, shit inaccurate as well. While it's kinda useful for raining down arrows on enemies during sieges where accuracy aint gonna matter, it's ultimately a piss poor weapon for the battlefield. That's pretty much why they've never been used in later ages & there haven't been any actual surviving bows to be found.
There were always doubt of how powerful these historical repeating crossbows were. From what I gather from all these information, the Chu Ko Nu's were really weak. If shot from a reasonable distance like more than 30 meters away, their bolts probably could not even penetrate a decently made leather, not to mention any kind of metal armor.
@@gigaslave Please. Those poisons could only work if the bolts manage to penetrate their targets, & bolts fired from these bows were too damn weak to penetrate just about any kind of decently made armor. if the bolts were able to penetrate enough for poisons to work, poisons wouldn't be needed in the first place.
Oh golly! Remind me to *never* attack Joerg Sprave's home. The last thing I would hear would be "Let me show you its features.", and then a hearty laugh... Deepest respect, love the channel! :)
"We must understand that this is a movie prop, so it doesn't have to shoot very hard." I highly doubt that movie prop is actually functional at all. I actually went to Prop Store's website to inspect it more closely. It's so crudely made that it would probably be more hazardous to the shooter than anyone standing downrange if you actually tried to fire it. The bolt (which per the website's description is plastic) isn't straight, the path the bolt follows isn't straight, and most worryingly, it has metal string stops that will probably damage the string very quickly...
Usually the props will shoot, but extremely weak. Then the CGI guys can easily exchange the weak bolt with something powerful, rendered in the computer of course.
@@acsimark Forget the lever - because then, you shorten the power stroke and the power of the shot goes down too. There is only so much distance your hand can move over. Physical work is force time distance, and this limits the power of a high rate of fire weapon that is cocked back with one hand.
@@Slingshotchannel thanks for the answer. I personally reached a point with my bow skill, where the limitation of rate of fire comes from the lenght of my power stroke aka draw lenght. I use similar technic like Lars. I think the point of the lever + on sliding anker point is that the force direction has less friction + the cocking gets lighter and you can use body weight. I would use a curved lever. The first design could get doublé as strong, and let us dont forget that the bow has the highest power potential on release, after release the arrow quickly overspeeds the string power delivery.
I found your videos when I was in hospital with my wife having our first child. That was almost 6 years ago now. I am no less entertained now than I was then, please keep these inventive, funny and awesome productions coming!!
As he states usual german efficiency here depends on replicating.. and fast video production But you can't use bearings in the string neither arrow Loading depends more on the strength of the bow ..no worry friction there
Yeah bearings are an anachronism. But he could use lignum vitae wood. This was often used for low friction wood mechanisms, although I think it only came to Europe after the crusades, so it would still be not strictly legit, period wise. But a lot closer than bearings or linear rails.
I think you could harvest more force if you had two charging handles on either side of the slider, with their midpoint in line with the string. You'd have a large chest pad on the back so you can really pull with both arms. It would be clunky but at least you'd be able to pull a decent 60# bow, not quite a 120# war bow or an armor-piercing crossbow but still a somewhat usable weapon.
Jeorg! Your “home” is a castle worth defending. I haven’t watched many of your RU-vids lately but so glad to hear your infectious laugh and “Let me show you it’s features.”
Just wicked.watched 1 of your video 3weeks ago and within 30mins I bought a rx adder..awesome piece of kit and great fun..bloody powerful though took me by surprise tobe fair.
@@acsimark Well, I just read your (other) comment and I can't see any lever neither in the film footage nor in the auction site pictures - I may however just be missing it. At any rate, I do believe some sort of lever (eve a medieval style goats foot type of) could be applied to the first design, thus allowing it to fire a stronger bow. But then again, as far as making a functional movie prop like the one depicted, I think Joerg's first design works just fine. And then, on the second design, Joerg used a completely different design, much more functional and one that is more in line with his previous Fenris / Instant-Legolas designs (bows with magazines) than with a crossbow. But that does come much closer to delivering the actual effect the movie prop simulates than the prop itself likely would.
Now imagine how powerful a modernized ballista/scorpion bow turret would be.... If anyone could make such an awesome weapon it's gotta be you sir!!! Great video, really got the brain juices flowing!
On the last variation: I wonder if adding a second handle on the sliding mechanism and a chest plate on the body allowing you to use both arms to cycle it (kinda like a jim rowing machine) could help even more. Edit:bad grammar
i really like the rowing machine reference. It would be awesome to create a row-bow, using the combined force of legs and both arms to pull back the string and release by trigger similar to the here shown mechanism. Only complicated thing is to transfer the energy into the line of force of the senew. Taking a chair-sled to slide on, pivot a crossbow on top of it and have basically the design in the end of the video, but more powerful.
You'd probably need to add a mechanism to make gross and fine adjustments to the angle of elevation but that'd be pretty cool. Not sure how Joerg could show it's features without risking that cam drone though.
Manchmal ist er ja ein bisschen komisch ,aber technisch ist er ja echt ein Genie.Echt Wahnsinn was der Kerl in seiner Werkstatt so alles zaubert,Hut ab davor.
Joerg, you’re always a great source of entertainment for all ages! You are awesome! May I suggest trying your hand at a mongol Hwacha? It would be very interesting to see how you would put your spin on that ancient siege weapon. Great job as always!
@@michaelpettersson4919 that’s why I said I’d like to see his spin on it. See how he’d power it with rubber or something. Seeing as he made a “RPG” replica, I don’t see this being much different.
@@itsyourenotyour9101 German arms laws are crazy strict. Yes, you can, and he does own firearms, but manufacturing your own is a whole other kettle of fish. Also there is a crazy amount of red tape.
@@sinisterthoughts2896 Yeah, I can't comment on their laws. But from what I gathered he could do it, but in terms of RU-vid in Germany and in general they don't want that being shown, which is why usually his "gun-like" projects have like, I don't know how to say this, you have to place it over where the air comes out for example (classifying projectiles).
You are a real genius bro. I love like so much. What I most like is your victorious happy laughter 'Haa Haa Haa' after doing a wonderful job. Accept love from Sri Lanka.
Great video joerg, your engineering skills always impress. I have no idea how you’re able to make such complex contraptions so quickly and out of plywood no less. Keep it up!
Great piece Joerg. The question is not, IF YOU mastered the challenge, the question should be, if there is any challenge (concerning rubber, string, spring, air or muscle operated or bladed weapon) in the world that you could not. 😁✌
Good for u, u have a TV show now!!! U deserve that, and actually u deserve more!!! U r so energetic, hard-working man, very kind and patient and finally and most importantly ur great imagination with smartness and experience... I'm actually proud of u!!! Greetings with love, All due respect sir... I will watch it inshaallah...
You could trigger it with tripwire, but reloading it seems really hard. Even in a perfect system, a falling weight couldn't muster more power to reload a crossbow than it can deliver dropping on the enemies head, can it?
@@trogdor8764 A hand crank isnt really automatic. And a heavy weight could power a pretty powerful bow. It's just about adding more mass. I'm just curious if it would be at all possible. Would be really cool.
@@trogdor8764 Machine guns are typically manned by two people and such a weapon could do something similar. The gunner would then not have to worry about feeding the weapon since his loader operates the crank.
A delightful thrilling movie and a cult classic, and with *the* most dedicated fans you will ever meet who will debunk all of those haters spreading lies about this movie 😅 the Robin Heads are the most passionate fanbase in cinema and we long for Robin Hood 2
@@ChainsawFPV thanks probably I will watch it as a Robin Head I am a big fan of all things green 🙏 idc if its comedy as long as its respectful of our hero
Absolutely you have stepped up to the plate in masterful fashion. Fantastic engineering as always dear Joerg. I salute you for your fertile mind and amazing imagination. Maximum respect from Cape Town - South Africa. 💖
Great video as always Joerg, proving that you can reproduce the prop. And then showing us a way to improve it! And now you should make an Instant Legolas for the auto aiming bow from Stuff Made Here. That would be awesome!
It seemed to me as if the original idea for the movie was a “modern” Robin Hood of sorts. The way the crusaders were dressed (scale mail vests VERY similar in look and shape to bulletproof vests), the repeating crossbow being very analogous to an M2HB .50cal, the way the crusaders were armed (all bows, ie all guns) and pretty much all of the costumes. I wonder if it would have been better as a modern movie
5:29 That weapon by itself would have made an *wonderful* episode for whatever old and new "Robin Hood" TV series! 🤣😉 Sheriff or/and Prince John: "Now we will have him! *MAHAAHAA!"*
Agreed so so so true ❤❤❤ I was glue to the screen every second of that delightful movie 😍 and haters and trolls who haven't even *seen* the movie called it a flop ....
@@jameshateseverything1356 It quite literally was a flop though in every sense of the word. People can argue over whether they liked it or not, but facts are facts.
@@Musabre it may have been considered a financial failure, thats true but flop is the wrong turn due to a dedicated fanbase hence making this a "cult classic" ... it was a financial flop yes but not an artistic one 😍
@@jameshateseverything1356 That's subjective though. And a 'flop' is a movie that doesn't live up to expectations and fails at the box office or simply overrall. Which 2018 Robin Hood most definitely was, again objectively, not an opinion. I personally thought it was a terrible movie for many 'artistic' reasons, but I'm aware of the difference between my opinion and facts. You're right in one sense, it's not the first total flop to have a cult following, and it won't be the last of course.
@@Musabre That is an opinion. you cant claim things are objective when they are not ... yes objectively it did not make much money but in my subjective opinion that did not make it a flop, maybe yours it does, but thats still just an opinion. And before you say your definition of flop is objective, remember the phrase "commercial and critical flop" if flop meant *only* financial results of the movie there would be no need to specify critical response which is not related to the finance .
Here's another idea for a mounted defense: what if the bow and the seat were integrated together into one unit? With a setup like that, you could engineer the bow to be drawn by pushing with your legs and pulling with your whole body. Basically, imagine a rowing exercise machine, but using that motion to invest a huge amount of strength into drawing a powerful bow. Something like this would probably take a two man team since you'd like need someone else to handle the aiming part, but the power and rate of fire you'd be able to achieve would be extreme.
Edit: Wrote this before seeing his second modern version. But I still think the suppressive fire would still have its place and just the fear it would cause in the enemy, especially in the time before full plate. Imagine having like 6 men in a tower on a corner of castle with more powerful version of this, one man shooting and the others refilling magazines as needed. They could really get alot of suppressive fire from this system. Like the medieval version of a tower in a tower defense game. With a more powerful bow being powered by like a pulley system connecting to a handle like the OG gatling guns.
Here's something rather different to usual, Joerg! How about a mechanism, where the initial 'shot' releases a catch which 'fires' a blank and pushes a sled which forces the string back behind its catch and repeats the function? Who said 'powder' had to propel a projectile forward, when it could just power the mechanism instead?!
I think it's a cool concept, but... When a bow fires, it transfers a lot of energy into the arrow it shoots. With a blank shot, this energy can't transfer and this is really bad for your bow.
@@BlitzBobNoPants To be fair, the "blank" wouldn't be as harmful to the bow as a true dry-fire, because it would be transferring the energy into the repeating mechanism.
