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
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
"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.
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.
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
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..." ;-)
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
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."

"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.

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!
Hey Joerg. I just wanna say, I think this is some of your best work engineering wise. You're a real inspiration to me with all these amazing designs. Never stop creating.
@@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.
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. 💖
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.
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.
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.
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 UA-cam 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).
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.
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
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
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.
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.
Man, I like that drawing and firing mechanism. I wonder, you think it's possible to scale this up in power even further? Say you can somehow make a tripod that can quickly hook into the ground and use some 2-handed drawing mechanism like seen here to launch even denser bolts? Could be like.. the m2 of the crusades lol
He covered it in the video. Not really, it's a bad design, the more power you add, the less efficient it gets at exponential rate. It seriously can't even operate at a certain point due to the lack of efficiency(entropy?). What he made is about as good as it can get. It isn't that it gets harder to use(which it does), but the fact the device will start freezing up when dial up the power.
@@sinisterthoughts2896 isn't that just a consequence of it beeing directly muscle powered instead of using a remote power source, like a treadmill and various mechanical linkages to draw and fire continuously when the power train is connected by the shooter
@@SonsOfLorgar no. The reason comes from friction with the sled, which is a byproduct of using a bow instead if two independent limbs. Everything is at a cant. If he wasn't trying to make a period, movie accurate version he could engineer around a lot of the issue, but there would still be some there. So it could be mostly remedied by changing the design criteria, in my not very educated opinion.
Hi my friend, I love your show and even though it's around a year or better I must say that, you are,THE KING OF SLING'S AND BOW'S. you do an excellent job concerning your craft!!! Please keep the great work up. Thanks for everything
Literally just made this exact comment then found this :) I was thinking the same. The round magazine looks big enough that you could have pretensioned shots in it, and the crossbow just contains the mechanisms to rotate and release them.
@thewulfseye but you could have a bunch of them already preloaded. If you have enough to deal with one attack you can reload them later. Or have a crew reloading them for you while you fire.

IMO the challenge was mastered on the first design and bested on the second. Congratulations!
Not really , check my comment
@@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.
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. 💖
Man, this videos can cure depresion. Thankyou very much.
Love the sound effects with jörg laugher.. haha😂😂😂
It's so much fun, watching you as you explain your projects, you have a infectious laugh.
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.
@@FalconWindblader They compensated for the weaker auto-crossbows by using poison-tipped bolts.
@@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.
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.
Yes, he met the challenge. Was there ever any doubt? He's having so much fun; I wonder for how long he played with it after the end of the video.
I'm betting at least an hour lol
How about some hidden roller bearings to reduce friction?
Really cool machine bow!
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
Or linear rails, would make it a bit heavier and more expensive, but the friction would be gone!
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.
Great Vid Joerg. Seeing how much fun you're having makes it fun for all of us.
Wow, the own design takes the cake. You haven't mastered it, you have killed it!
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!
Well, the Hwacha is a firearm and may as such cause legal problems.
@@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.
@@michaelpettersson4919 Pretty sure he can own firearms. He talked about it once.
@@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 UA-cam 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).
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.
i hereby challenge Jörg to make a row-bow
@@TheMrRoflchopter 30 round magazine, 100lb pull force ;P
@@TheMrRoflchopter that would make an excellent naval weapon
@@TheMrRoflchopter : LOL ! ABSOLUTELY ! 🤓
Your truely a legend my friend. I've watched your vids for years and I just love your channel.
This man is truly amazing. The things he makes is just insane. Great work!
😍
I appreciate the extra effort you've taken for the filming, with a variety of camera angles and backgrounds.
Everytime I get in there, I'm also blessed with a new Rpg idea. That would be very good for stationary places than have to deal with flyers.
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.
@@darkbringer1440 and a LOT more power, AA-weapons need to be more powerful than direct fire surface to surface weapons for the same range.
I mean my god this is absolutely ridiculous how fantastic this is... and we are watching this for free.
Every time that I click on a video of this man I always think the same: "This guy is crazy!". I have enjoyed every single one.
This man, he scares me, but he’s so wholesome
Why?
Because he is a German?
Because he is a smart?
Because he is a man?
All of above?
@@AKUJIVALDO no, he’s built like a house and is so cheerful, and he could snap me
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!
You're a genius when it comes to wood.
you could call him a mad scientist. ❤ love his designs👌👌❤️
Joerg never disappoints!
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
That is a beautiful home and quite the piece of land love the foliage.
His laugh always makes me smile 😃
Yes, like everything he does, it looks and performs great. Having it mounted on the tripod at its center of gravity would make it easier to handle.
New challenge: being in a tower, could it be rebuilt to be truly automatic? I'm thinking that maybe a falling weight could power it somehow?
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?
watch his older video
He's already made a repeating bow using a power drill, so you could surely make the same thing with a hand crank.
@@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.
Joerg, you truly are the man to make the movie magic real. Thank you again!
Joerg: I really enjoy your mechanical genius. From what I see, your castle is safe from the Crusaders
I am supremely confident they were inspired by you when they designed that scene and that prop.
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
What about Robin Hood, Men In Tights? That was a classic!
@@ChainsawFPV I have never seen it
@@jameshateseverything1356 Its a comedy based on Robin Hood. It is actually pretty funny.
@@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
Thanks a bunch
Joerg, you magnificent bastard!! Your the ultimate combination of evil genius and lovable teddy bear. Awesome as usual!
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.
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.
@@penedrador Batteries didn't exist in medieval times.
@@BlitzBobNoPants You would need to have a small exhaust for the gas, and a cartridge release mechanism, but that would only need to be very small
@@onbedoeldekut1515 damn
@@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.
Your ingenuity is truly impressive!!! Keep up the great work!!!
This guy's expertise experience engineering skills and strength attention to detail is top 1% in his hobby
Man, I like that drawing and firing mechanism. I wonder, you think it's possible to scale this up in power even further? Say you can somehow make a tripod that can quickly hook into the ground and use some 2-handed drawing mechanism like seen here to launch even denser bolts? Could be like.. the m2 of the crusades lol
or maybe some kind of lever like on the adder...
He covered it in the video. Not really, it's a bad design, the more power you add, the less efficient it gets at exponential rate. It seriously can't even operate at a certain point due to the lack of efficiency(entropy?). What he made is about as good as it can get. It isn't that it gets harder to use(which it does), but the fact the device will start freezing up when dial up the power.
@@sinisterthoughts2896 isn't that just a consequence of it beeing directly muscle powered instead of using a remote power source, like a treadmill and various mechanical linkages to draw and fire continuously when the power train is connected by the shooter
@@SonsOfLorgar no. The reason comes from friction with the sled, which is a byproduct of using a bow instead if two independent limbs. Everything is at a cant. If he wasn't trying to make a period, movie accurate version he could engineer around a lot of the issue, but there would still be some there. So it could be mostly remedied by changing the design criteria, in my not very educated opinion.
maybe can you make it a hand crank version of it, like those old maxim gantling gun that spins around
Challenge has been mastered. Love this channel
Hi my friend, I love your show and even though it's around a year or better I must say that, you are,THE KING OF SLING'S AND BOW'S. you do an excellent job concerning your craft!!! Please keep the great work up. Thanks for everything
what if some energy is already stored in the magazine?
only 6 arrows means a ton of space in those magazines for something crossbow-like.
idk.
Literally just made this exact comment then found this :) I was thinking the same. The round magazine looks big enough that you could have pretensioned shots in it, and the crossbow just contains the mechanisms to rotate and release them.
Yea that would explain the large size of the magazine.
@thewulfseye but you could have a bunch of them already preloaded. If you have enough to deal with one attack you can reload them later.
Or have a crew reloading them for you while you fire.
