Based on the size of the crossbow, it looks like it is a crossbow named 'yongdusamsisuno(용두삼시수노)' As a Korean, I feel happy to review Korean weapons.
Bro didn't need to say "I'm in Canada". The Crocs reveal would have been sufficient
This particular design of Korean repeating crossbow is actually from a 19th century military treatise. We don't know if earlier designs are different or not. Imjin War era Korean repeating crossbow may not be all that different from Chinese ones.
The Chinese had various designs including large versions drawn on wheels
I agree the artwork took liberties of the 19th century, although the depiction is quite similar to early artwork of the earlier Joseon era. Perhaps the dimensions were smaller and more akin to a Chinese chu ko nu, with a much faster reload. Nonetheless my experiment of the larger design clearly shows you can’t expect the same rate of fire compared to a lightweight smaller repeater
There were also smaller repeater crossbows in similar style. I have seen a reproduction of those, but had not heard about these bigger ones. Interesting and I suppose upscaling the design gave it more power than the smaller ones that could be used without a tripod.
Yeah I wasn’t as interested in the smaller repeaters since there are tons of vids on RUclips
Giant repeating crossbow + Crocs = Awesome. Lol
Great video man!
this is a really cool demonstration! that's an impressive crossbow
Holy cow that is amazing. The Koreans had some top tier tech
This is a weapon invented in ancient China, called Zhuge Liannu. Koreans just copied this weapon.
@@user-nm1bx4dz5j well they also improved on it
@@user-nm1bx4dz5jzhugeliang copied the Bronze Age design
The historical instant Legolas
Let me show you it's features 😄
Excellent demonstration dude, and the commentary is on point. Really does seem like something that wouldnt change the tides of war but definitely useful.
i dont know in naval terms good luck boarding a ship with 10 of them aimed at you as u try to board with planks or grapels, if u werent very armoured it would punch thru multiple ppl on deck if you where youd have broken ribs to fight with still if not a arrow in your chest to distract u
I believe they use it more like a fast reload sniping ballista than a machine gun. Firing from a castle wall allows for much heavier bolts at close range, specially with a 2 person crew and a much heavier bow (300lb or more).
A heavy european crossbow has a solid 4-5 minute reload time if I remember right(?). This definitely feels like something I could sit on the wall and shoot for hours, and have solid accuracy. Maybe not as much as the bowmen, but enough to keep heads down.
I think the roman version still had two feather fletching, which I’m sure drastically would help the accuracy, and wouldn’t be hard to add to this design if desired.
This reminds me of Age of Empires 2 campaign where you get play as Admiral Yi and you gain the Chinese unique unit the Cho Ko Nu.
Besides shortening the stock, a bend in the cocking lever would make it less awkward to use without loosing leverage. You don't seem to need all the leverage you alread have, so room for an even stronger bow. : D The Roman ballista had a two person crew. Imagine if you had two guys "rowing" this thing.
Haha can shoot 500lbs
LOL your repeating crossbow was more of a bolt-action crossbow. But holy cow man! That thing shoots like a sniper!
This is so beautiful, I love it.
Mythbusters introduced me to the repeating ballista from Rome, and Todd’s workshop introduced me to the belly bow from Greece, but this feels like such a cool parallel invention and I think one case where Asia definitely beat Europe.
A smaller version. Guts from Berserk has one mounted his metal arm, and yes it is an anime and fictional, and bough based on a real dude. My point is he has exactly the same weapon but like pistol sized and it operated with a crank handle. Good engineering and good idea, I should say.
What’s the point of a smaller version where there are hundreds of smaller ones on RUclips already
his also had a crank, which i'm curious of how that mechanically would work, it was essentially a gatling gun crossbow lol.
@@Yojimbo61 me too. I’m sure we could build one just like that
@@busurbusur2381 because it’s medieval times so it would have been novel at the time.
Guts is not based on Gütz, the similarities are coincidental as stated by the author.
even if your wearing armour broken ribs arent fun, it dosent need to go through armour to break a rib underneath
The smaller one is designed to launch poison. Considering the context of imjin war they lacked skilled archers and poison so this was a choice since it can substitute archers with strong bows while civilians like the elderly and women build these devices
All archers used to poison their arrows historically, there is a book written regarding archery wounds throughout history and the prevailing story is that the wounds festered and blood was soiled. English archers apparently dipped the broadheads into shit, they also left them lightly attached so if the arrows were pulled the head remained.
This was one of the reasons why the crossbow became so popular in Europe, despite of a Papal ban decrying it as an "Evil and perfidious machine" and the longer time between shots compared to a regular bow...
Archers, especially warbow/longbow archers, have to train incredibly long and develop crazy back and arm muscles to effectively utilize their weapon. English dominance in the Longbow was because of mandatory training periods and practice gained in hunting small game in the commons...they could field so many, because this was done all the way down to the peasentry, allowing knights and lords to levy up entire archery batallions to fire en masse, instead of what you'd usually do with the peasents in war...canon fodder with spears and other polearms (...which is why a lot of polearms have connections to agricultural equipment like the guirsame or billhook) assuming you fielded them at all, instead relying on middle-class mercs and men-at-arms exclusively to fill up your formations.
The crossbow on the other hand, especially with winch-assisted loading...you don't need that labourious or lengthy a training period. You load, aim, and pull the trigger...almost anyone could use it, and learning it use effectively enough for a mass fight/siege didn't take all that long. Low barrier for entry.
Same idea behind the proliferation of firearms later on, especially after peasent levvies gave way to professional armies and drafted conscripts.
This is so cool to look at because, if you think about the time it takes to train a bowman, and then having this for someone who's relatively not as trained, is an amazing asset to have. Follow up question, because I know you've talked about different use cases for arrows, was there a similar situation regarding bolts? Fascinating stuff!
Exactly plus civilians and women can build this instead of spending years to train skilled archers
Wouldn't it be better if the part close to the belly was shorter?
He mentioned that
@@marcellusbrutus3346 ah haven't finished the vid yet
comically oversized zhuge repeater lol
Amazing that there was essentially a semi-automatic crossbow in the 16th Century.
It already existed in 400BC china
@@marcellusbrutus3346 wow that’s amazing. I love ancient innovation
The Bronze Age versions are much faster and compact but very weak and rely on poison
@@fatboy8420400 bc that’s Iron Age
Ancient China already had that. They were the first ones to also have gun powder guns. Europeans took the gun innovation and made the guns better.
I’m sure the biggest problem with those crossbows is string wear
Maybe they wire wrapped the string at wear points
This is why the concept for historical version of "Instant Legolas" could arguably be groundbreaking in past timelines. It's more powerful, more accurate, more mobile, faster ROF, faster reload, easier for novices, personal weaponry, etc. Even than, Joerg's historical version of his repeating crossbow design is also much superior & would have fare better than historical Chu Ko Nu.
Let me show you its features.
no, only in the 21st century timeline lolz
@@andrewtamo3814instant Legolas uses many modern parts such as rubber bands and springs
@@siberiaacoustic i googled and it said rubber bands was invented in 19th century and coiled springs in 18th century
i am not that far off but if i could add the instant legolas does not have a lever like the chinese/korean repeating crossbow and will tired the user more quicker
Hi
If the stock were shorter and the cocking lever a little longer, you would reach the lever and not have to fight with it.
Rock out with the Crocs out! :P
Essential
Awesome I love this style of chu ko nu crossbow, these are amazing. Korean history is fascinating.
That is one big beast, nice one!
This looks sooo fun to shoot ! Wish I could try that, really ingenious design for the times. Very fun episode to watch 🙂
A Korean ghost is laughing when you tell us about it’s features
Nice pice, Joerg Sparve would approve I'm sure.
So why didn’t the Chinese do this
They probably did, there is just no record of it.
They did with records in Han dynasty
Finally the long awaited video has arrived
Yeah it took half a year of procrastination and editing. Check the weight a lost lol from this video and my most recent shorts
You sure your not in Scotland? It rains the minute you want to do something! That's a Daylite bow you got on that! haha! Awesome got one myself and i love those bows.
Love the short history of the crossbow and i love korean history, it would be interesting to measure the power of one of those large heads because the heavier it is the more impact is should have. The weakness of the lamaller armour is it does have a lot of spaces between plates and with a high rate of fire i think you increase the chances you will hit one (this is pure theory). I don't think its slow as you think (not knowing the power) if we compare it to an arquebus for example that had an extremely low rate of fire...i think you get off like 20 bolts for 1 arquebus shot. I don't know this but I am guessing not all sailors wore armour? I am projecting European style onto Asia here so I could be completely wrong but if that is the case then rate of fire is much more deadly.
Made smaller, so you can reach the handle easier and with the brace height correction...i think its pretty good.
Admirals Yi Sun-sin and Horatio Nelson are almost as comparable as Lincoln and JFK. I have two books that Admiral Yi wrote, one was his diary and the other his professional journal. He mentions doing his archery practice and unlike the thousands of history books it shows his human feelings and habits. It is possible that Nelson may have been influenced by Admiral Yi just like Napoleon was probably probably influenced by Sun Tzu's Art of War. Translations were prized items...
The problem is he is Korean so nobody cares internationally. But if he was black omg
Awsome review, sorry for not working as it sohuld be, i had a different brace hitght with my bow so it knocked correctly and could shoot as repeated crossbow. Since it was my first time making sucha big scale crossbow I would make many things different with the second one and make it shoot easyer and smoother.
Awsome history behind it and shooting to.
super cooooool!
I think that one major problem with making a weapon like this way too big is that this type of weapon was originally meant to make it easier for a relatively untrained individual able to fire at targets/enemies relatively quickly and once it becomes so big and once it becomes so powerful nobody is going to be able to fire that thing at any speed which resembles rapid so therefore the idea of building a repeat firing crossbow which is very big and is very powerful begins to start defeating the purpose of what the weapon was intended to do in the first place.(Or in other words once you make a repeat firing crossbow which is way too big then you might as well just use a balista)
There’s certainly a balance for sure. Mine could of been more ergonomic for sure to improve reload speed but there are limitations and it will never be as fast as a small chu ko nu
Please make an improved version!
The Korean navy, actually had a Navy, and Navy trained people, the Japanese just had a bunch of transportation ships. Also the Korean ships had cannons, i'm not sure how many of the Japanese ships had cannons. The japanese though just because they could overrun the land, they didn't realize or properly understand logistics.
They still outnumbered like 100:1
@@legntt3488 Cannons, and good weapons, and training makes that much of a difference. Look at the Portuguese in South East Asia earlier in the same Century. Even when the Ming did beat the Portuguese in a battle with insane numbers in the early 1500s they copied their breach loading cannons. I'm curious if the Korean ships also had those Ming style breech loaders.
@@Yojimbo61all three factions had cannons of similar technology albeit none of these are the decisive reason why Korean navy was able to defeat the Japanese. It came down to many factors but admiral yi is certainly a legend
Look up Ships during the imjin war, and you will see a massive difference. The korean turtle ship was bigger, armored, had more cannons like 22-24 cannons. While majority of Japanese ships did not have cannons or had like 3.
If you don't think cannons are one of the decisive factors, just look at the Siege of Malacca. The Malacca sultanate had cannons but they were not comparable to Portuguese cannons. The portuguese could win battles against massive numbers, and cities just using their cannons from their large carracks.
I don't doubt Admiral Yi is great, but he would not be able to utilize some of his tactics unless he had the better ships. Like funneling in enemy ships, and engaging them at further range, etc.
@@Yojimbo61 I understand the ships were much larger but from the records I believe they were outnumbered 10:1. The Japanese did have cannons too, thanks for sharing which side had more. It is clear that admiral yi put considerable effort investing what mattered like cannons on large ships similar to how European caravels dominated the battlefield soon, and it was Yi who made the decision on procurement of the correct ships and design. Anyways back to the repeater crossbow, it’s just a small snippet of the history and obvious I don’t have the budget to make ships haha
Turtle ship
One factor for sure, of course good leadership is key
In environment where powder gets wet and makes the guns useless that crossbow would be good to have. Kind of like the gatling guns they keep on ships now...
Good job. Thank you. Easier, quicker, and cheaper to make than the composite bows that went in them. If you had time, and your life depended on it, you would probably work out the kinks.
Why not just use wood instead of
@@skyrimJava can't be made as powerful as it needs to be with a prod/bow that short that won't break too easy.
@@mikeorick6898could be made just over sized lol
An important limitation for power of the lever design is the short draw length. What is the draw length of this larger model though?
26 inches for some ridiculous size but power
Cool 😮
Yes
Good
Does thumb ring increase rate of fire
Wololol
Thumbs up
Great video Jack
Glad you enjoyed it
Hey! Did you mix up centimeters and inches again?☺
Use the metric system (centimeter) only when drawing plans.
That things so cool 😂
Was gunpowder in use on Korean naval vessels prior to the 14th century?
Yea similar to early ming weapons
So, you could build a taller magazine to hold more bolts yeah
How much power in lbs can that crossbow have?
It’s equivalent to 100lb composite bow
Where in Canada are you from? The forest looks like it's in British Columbia.
What is the bow being drawn to ? Maybe if it’s not fully drawn you can shorten the bow string so it loads.
26
@@HistoricalWeapons what’s the max draw ?
100lbs only?
100lb@26” Still doing around 230fps @ 600 grain. I cannot find a Korean bowmaker that makes a heavier bow so instead of using a heavier bow that is not Korean, I’d rather stick to this
Man stop complaining it’s obvious that it’s already clunky to operate
Let me show u features
do you consider this a repeating or a semi automatic weapon?
Semi auto is a firearm term
Admiral Yi💪🏻
Artillery
The cocking lever seems badly designed, as it is almost out of reach. Could be tweaked by using a bent arm that brings the grip handle into comfortable reach, or just even a thick rope on it that allows you to pull from closer to your body. Always love Chinese repeating crossbows.
연사가 안 되는 건 아쉽네요 잘 봤습니다
It's a shame that the crossbow hasn't been continuously fired.
ruclips.net/video/hRowp9EF8kM/видео.htmlsi=QWwYNGvFW0hobIJe
In reality, it's possible to shoot continuously like the video above
That version is much lighter in draw weight
And the continuous fire you mentioned is only possible if the bow perfectly match the stock
@@dsasd778 I know about that, Books also show a high-pound crossbow. They will also shoot consecutive rounds. But no one in Korea actually makes a high-pound crossbow. This is homework for Koreans to solve thx
@@user-ud2th2og6othe slight difference is negligible for a artillery size here in terms of time spend cocking string
This manual load method allows any bow to mount onto the machine, which means it’s easier to replace when the bow breaks. Or else you need to match brace

Wow, I didn't know the Japanese ever had it that bad. Fighting against the Koreans at their naval peak, when they started putting metal in/on the boats AND The Ming. They're lucky to still be a country, let alone a race. Not saying those empires were that much stronger than Japan at the time (But they were), they were just RUTHLESS.
Pretty sure the Japanese at that time had veteran soldiers from previous internal conflict very recently while the Koreans and Chinese were complacent from peace so lower morale and experience
@@HistoricalWeapons Ah, I was misled by some sources to believe that they had good tech at the time
@@gaddiusgaddium9082 by the time Japanese invade Korea, both sides and Ming had guns and cannons. Technology was not the limiting factor but rather morale.
@@HistoricalWeapons Oh, that's not what I meant, I was saying some iffy "documentaries" lied about how advanced they actually wwre. But I appreciate your information, I'd rather be well informed than misinformed.
crossbows of China started out in the south and spread northwards the Han dynasty probably popularised them since it was founded by the Descendants of the Chu kingdom and the Chinese ruled over parts of Korea foe some time as well
Crossbows are invented in Africa
@@skyrimJava it is possible from the Stone Age we have no evidence
🗿👍
The The lever is too long! Unfortunately, the geometry doesn't fit.
The original crossbows were war tools (they were used in this size on castle walls, ships and against cavaliers).
It's nice to see another repeting crossbow. I have built a few myself. The one on the video is unfortunately nothing more than a prototype. :-/
Here is a link to a smaller version of mine. Incl. description. (Unfortunately only in German)
ruclips.net/video/JerghI7tVqQ/видео.html
by the way: "my one" is a smaller one. (For home defense)
Smaller lever is even harder to pull the draw weight
I think I may have bad news... the painting you showed is often said (and ive fallen for it) to be historical and from Joseon era. However when you look closer you notice that the japanese are pefectly accurate which is odd if this is a korean painting. it's just that it was made in the 20th century or more recently than we might think
Evidence please? That’s pure speculation
@@dsasd778alright, looking on Korean websites, it's attributed to Tenyo Ota, born 1884, and was active in Korea as a painter and archeologist as well as a japanese soldier.
There are written records of Korean repeating crossbows and Chinese repeating crossbows. Those paintings give us a glimpse of what they could of looked like
@@marcellusbrutus3346 oh yeah absolutly but I think it's better to use the korean manual drawings than the circa 1900 japanese drawings based on said manual drawings.
@@theghosthero6173 japanse drawings of 1700s already show giant repeating crossbows
