Pretty good attempt! A few issues... first, you need to "fire" earlier as the arrows still have the downwards vector from the spinning wheel. You WILL need fletching to stabilize the flight, as you can clearly see that the downwards force makes the arrows tumble in flight. A "real" trigger/lock instead of the "push upwards" system would also increase reliability and flight. My verdict on Leonardo's invention is fairly negative though. It somehow works, but loading the weapon is cumbersome and outright dangerous. It would be almost useless in battle. If all you want is 16 shots in a short time, then it would be much easier to simply mount them in four stacks with four crossbows each, then pull all of the triggers at once.

@@33mavboy It's more that the operator applies fire to the weapon to make it do something. The first gunpowder weapons the user literally applied a flame to them, and cannons retained this approach for many years. Because waving a flame at something is pretty annoying to do and prone to the flame going out, hand held weapons developed quite quickly to generate the fire for the operator relatively automatically with this moving from match lock (consumable fire starter) to a wheellock (sparks through friction), to flintlock (reusable spark generator) finally to the percussive charges that we have now which are integral to the bullet casing.

My first thought was to put this in gate houses or to use it to harass people sieging your castle. Basically use it like a booby trap. Even with a low draw weight, it would definitely be a huge problem to deal with, and it would give defenders free time to do all kinds of things. Either way, great job with this one!

I feel like the only practical use for this would be on top of a fortification with several side by side, aiming up 45° or so with heavy headed bolts that can rain down on an attacker. As for the heavy trigger of the original design: wrap a rope around the handle shaft with a heavy stone in the other end, so you just need to kick it over the inner edge of the battlement to shoot it. One crossbow man/ DaVince machinegun that then picks up his normal crossbow. A good first salvo that gives the impression of far many more defenders.

Loading speed isn't as big of an issue if you look at this as a crew served weapon. You're going to need multiple people to move this thing around, anyway; they may as well be trained to load it. You would need four experienced people who communicate well. Two on each side, with one pulling the string (probably with a lever) and the other setting the bolt in place. As long as they communicate what they're doing and make sure each person is ready to rotate the wheel, they could probably get a rhythm going and load this pretty quickly.

Joerg Sprave and Tod of Tod's workshop made a crossbow with a magazine that would hold 5 arrows.

So 3 things would need to occur to make this a more viable implement than say 16 individuals with crossbows. 1. Automating the drawing process: You could use a hook plus gravity to help mitigate force needed to draw. 2. You would need a resetting trigger system: Which already did exist in the form of a rolling nut system, which would be period accurate. 3. A semi automated feeding system: You could use the Chinese hopper system with a flapper that only can be engaged when the crossbow makes contact with the flapper, maybe via some "teeth" at the head of the crossbow. And maybe a spoke and gear system could cut down on the amount of force exerted by the operator and maintain a more consistent speed, in addition maybe a treadwheel could also lessen the force exerted by the operator.

Hook and lever would work for the draw. In theory you would only need to engage the hook and draw. Once this is done you could load. Either by spinning the wheel once to unload, twice to draw, thrice to load. The unload trigger can be adjusted to the arch in which would mark yard/paces to about where they would hit. Trial and error would get this and I am almost sure that archers of the day would know how far their arrows would fly based on the angle to which they would release. Someone with some skills could do a cad design and make it work quite well. Though I have a feeling the war department did not spend much on research and development. Most of this was done by single persons who would either sell their new wares in a market or has connections to get it in front of someone. This thing is quite cool.

Considering how quickly this came together into a working prototype and the amount of available skilled labourers at the time it seems like you could realistically actually have a working high fire rate self reloading crossbow/Ferris wheel/turret thing. I think you could reach 500+ rounds per minute sustained if you had a internal track that caught the string and drew it right after firing rather than a rope attached to the axel so you are only adding one or two bows draw weight to the resistance rather than 16 and a loading mechanism just after the apex, maybe just an inclined track that slides the next bolt in. I’d love to see these improvements explored

Though it will be a pain and need some major work. Instead of 16 mounted crossbows, maybe make 16 housings for single crossbows to sit in? That way, at least in my head, you have one person loading the crossbow "bolts", one person spinning the device and another person loading the device with the loaded crossbows once the crossbows are empty. Higher reload, higher rate of fire(with extended usage), "easier" to use...maybe. Just an idea, but I never said it was a good one 😅

@Timmeh010 2 ай бұрын
that wont speed up things over just two crossbowmen loading and firing their own crossbows. loading takes way longer than firing obviously, so you'd have guy number 1 firing both crossbows (assuming they started out with 2 loaded crossbows) before number 2 has even reloaded one of them. theyre better off each reloading and firing their own crossbow. the only viable scenario i can come up with for this method would be if it's about marksmanship rather than volume of fire, and the one firing is a pro marksman who is then aided by some hastily drafted noob tasked of reloading.

@j.c.cannon2112 4 ай бұрын
a suggestion for if you decide to revisit this would be to introduce a ratchet gear. this way you could have a forward rotation be an equal 1:1 input for a high fire rate, then have a reverse rotation with gears in a 50:1 total input. this way the handle would be cranked 50 times for a single rotation of the weapon wheel, but due to the heavy reduction in force needed could be done quickly. allow for two reverse rotations to pull back each crossbow. with this reduction, with 50 lb. of force on the input, you could wind up sixteen 150 lb. bows. connecting the input shaft to your roman crane wheel would make the process nearly effortless. if you design the trigger mechanism to be equal to two rotations forward + the amount needed to position the crossbow, you could do one slow rotation to reload the bolts then a second faster one to actually fire. even if the total rate of fire isn't any higher, each one of these could be manned by one or two persons. thus the 16 persons become 8-16 crossbow wheels. pair them in sets of three or four, and you'll always have one firing while the others reload.

well obviously, but I think the idea is that you dont need 16 people to operate this machine, you probably can go with 2 or 3 per machine. So if you can get even just like 5 peoples worth of efficiency out of 2-3, you can boost your effective defensive power. Gotta remember that people are a finite resource as well. Although the main drawback would be how this thing cant be aimed properly. It doesnt really offer enough efficiency to offset the lack of aiming. Maybe if it actually gave 16 peoples worth of efficiency while only needing 2-3 in terms of fire rate you could just pelt the enemy with so many bolts that the lack of aiming doesnt matter, but the device has no automated reload function, so thats not really possible.

There comes a point where the shaft of the previous shot hasn't cleared the device and the next crossbow strikes the shaft as it is leaving deflecting the bolts trajectory. Of course you can make the wheel even bigger and space the crossbows far enough apart that the bolt has time to clear, but the device will quickly grow to the size of a Ferris wheel and require a significant amount of strength to turn.

totally fun and impractical for all the reasons you mentioned. I'm not sure you could ever really make it practical but if you could incorporate a mechanism to pull the string back as you turn it on the opposite side of the wheel, then you could put two of them side by side and fire one while someone reloads the other. forge welding f the trigger finger to the release at a 90degree would mean you only need to place the arrows in it. Alternating between two of them could enable a constant stream of arrows. Now for aiming it...

I think angling the trigger mechanism upward so that the bolts have a longer arched range would help, in addition to a stronger pull as mentioned in the video. This would make it more effective for at least slowing down a larger group of opposing soldiers. Also, reinforcing the ends of the crossbows with connectors between them would help prevent that issue with them breaking at the base.

Should make the piece of wood that triggers the crossbows pivot forward and backwards so you could get the wheel spinning and then push that wood forward whenever you’re ready to fire the cross bows.

The romans had a stationary self feeding ammunition drum, by crank ballista nearly two thousand years ago, which was WAY simpler then this and worked perfectly fine and didn't need to worry about a extended reloading period.

For the poundage of war crossbows go chech out tod's workshop. Heavy crossbows are 1000 pounds
@sypernova6969 4 ай бұрын
Wood bows and metal bows don't measure the same poundage though .
@alternator7893 4 ай бұрын
I would say 1000 pounds is on the lighter side for windlass crossbows. 1200 to 1500 were pretty common. Sir Ralph Payne Galway had a 2000 pound one from the 17th century

@@alternator7893 remember the more than 1200 # are very often great crossbows and are mounted like light artillery

Definitely something you mount on a wall or wagon covering a chokepoint and fire once.

It would be cool to attempt to build an automatic crossbow with linked bolts (fabric links?) Combine a crank with the repeating crossbow mechanism and run it similarly to a gatling gun (but belt fed vs gravity). Have a pawl linked to pull next bolt into the mechanism. Another linkage to pull the string back and lock it into position.

How bout a stationary cam located beside the wheel to fire the bows. Also if you could mount multiple repeating crossbows on a wheel that would be cool!!

You could make the device aim able by making the string plucking device adjustable.

That got me thinking, maybe a ball pitcher machine designed is also viable for ancient times which you feed bolts through a set of fast spinning wheels🤔

I could totally see this being put on a lazy susan so it's manuverable then adding the hooks you were talking about with some sort of pully system so that way all 16 crossbows can be reloaded at once. If perfected it would be an amazing defensive fortification against a besiging army. Imagine the horror of those down on the bridge when this monstrosity starts raining down a hailstorm of arrows.

I'd imagine that the fire rate could be made more consistent if there was one loader, and one operator. So the top half of the machine would be constantly reloaded. So it wouldn't need to be MG rate of fire, but it would be faster than typical crossbow fire (which crossbows were hard to reload at the time).

Good attempt at making it work. And yeah, intimidation is probably its best side. Although for any situation where few people need to hold against storming attempts? THAT is where it would absolutely be useful, as, lets say 4-8 of these covering the only 2 major openings to a position would make trying to storm in decidedly more dangerous to attempt. So, how about trying to make a lot more of those crossbows and set them up as a salvo gun? Preferably with some sort of improved reload system. For example, a simple system would be that you could have lets say 8 horizontal rows of 6 crossbows each on a mount/wagon, with each row being quick dismountable/mountable, with each row being possible to trigger individually, or several at once. This would mean operating it like a cannon, with reloaders dismounting fired rows, reloading them and then putting them back, while the gunner just stands by waiting for the best time to trigger one or more rows. Although, the idea has a serious downside, that it's made totally obsolete by the very historical H'wacha.

Just like the Chinese repeating crossbow, the utility of a weapon like this would be limited to defending a static position like a fort or castle, or being mounted on a ship, chariot or cart. The upside of using it as a static emplacement is that you could make it bigger and thus offset its biggest drawbacks (low range and power) somewhat. But like the repeating crossbow, its utility against armoured troops would still be pretty limited, hence why I don't think this was ever considered by anyone for use as a military weapon (in Da Vinci's time, heavy metal plate armour was quite common on the battlefield, making this a very ineffective weapon).

Next level? Combine the repetition of the Chinese into a Davinci wheel that drives reload cycle. Maybe 4 repeating crossbows on a wheel?

Not gonna lie, that is a handy piece of field artillery for it’s time. I just imagine 2 soldiers behind a castle wall snickering before letting it rip and making the besiegers think there was an entire company cramped in a single turret room

I would argue that the maxim was not the first machine gun. The Chambers flintlock machine gun was the first. It was used in the war of 1812. The puckle gun historically is also a machine gun used even before the chambers but had a very low ammo count.

I wonder if a combination of this and his trip hammer design would work, where you make a magazine like that chinese crossbow and have a spring pressing the contents down, and have each draw string with a couple of rods attached to it on either side of the cross bow. Have those rods somehow connected to something like that cam but have it inverse where it's pulling the string instead of pushing, and have that cam setup sitting stationary. The thought is as it spins it will pull the string back far enough to load a bolt and then instead of unlatching it, you're just letting it drop and move straight forward to fire. EDIT: You could have the springs for the magazine simply be a strip of bamboo with a plunger in the middle on top of the magazine, have it hinged at one end and the other would be held with a pin. The theory is that you simply pull the pin and lever the bamboo spring out of the way, then you drop in your bolts and flex the bamboo spring back into place, the plunger in the middle is to ensure you're pressing against the bolts at all times and it would help ensure that no matter what angle the mechanism fires at, you'll have proper feeding of the bolts into the system.

Have you thought to combine the DaVinci rotating crossbow weapon with a Chinese repeating crossbow; minor design changes to the magazine; to keep bolts frim falling out and to auto-cock the crossbows?
@ChosenTripster01 4 ай бұрын
just make each crossbow a self reloader and make the spinning of the wheel tied to drawing the string back, add a pully system or cog wheels to reduce the strain of spinning the wheel. have each crossbow with a reloadable "clip" for faster reloads on the field THEN you got yourself a gatling gun crossbow :p

I would love to see if it could not only fire but draw and load. I guess you could possibly do that with the box fed ratcheting crossbows. Maybe do a modern twist on the idea and do a joint project with The Slingshot channel..(”Let Me Show You Its Features”)..
