Well, the projectile is still connected to a string and not the top of the arm, so it's still a trebuchet, right? I'm new to r/trebuchetmemes, so correct me if I'm wrong
What I found interesting was the way the projectile stops the arm halfway through it's stroke as it flicks around. The magnets were a clever idea. Also appreciated your edit that superimposed the two designs.
It makes me happy that there are people out there like me that genuinely enjoy quirky small scale science like this. Like, I was just as excited as Tom was when he hit the can!
Can you imagine a "Modern Fantasy" movie, where the characters use these instead of pistols, much like how in that new Robin Hood movie they were handling bows as if they were rifles?
Amazing! After all these centuries, someone's finally invented the hand trebuchet. :) Very, very cool! As for accuracy, well, the trebuchet was originally meant to be fired at the broad side of a very large wall, you know. :) Thanks for sharing this. Nicely done! Wouldn't mind having one of those, as a conversation piece. :)
It would be intresting to use a non constant radius for the wheel. You could design the profile to compensate the decreasing force of the rubber to get a constant torque! Love your projects! Keep up the good work.
Great idea. Good execution. You should make an automatic reloading crossbow next with something like a 800 fps spring tension equivalent bow. That coke can will be blown to bits with such a metal ball bearing and that amount of tension.
You can replace the string with a piece of lightweight metal rod so long as you make the attachment point to the trebuchet arm a pivot. Then re engineer the projectile basket, preferably out of something magnetic too. Then finally redo the projectile magazine so that you feed from the bottom , but it pushes up to the topside and at the front, right into the reset position for the projectile basket. That should make for quick one handed single motion reloading of the projectile. Also for additional energy, you could add a second set of axle wheels on the exterior of the truss or third or fourth etc. Lastly, for aiming a set of peephole sights off to the side that are aligned for impact at various distances. Cool project. Would love to see the refinements in a part 2!
If it uses tension, isn't it per definition either a catapult or ballista (or simply slingshot/bow/crossbow), as opposed to a trebuchet? Those magnets were a good idea, although I still wonder how you intend to shield the user from failed shots.
@@armadillito gluing a welders mask onto the "gun" sounds extremely unwieldy :s Although I guess it could potentially be used to solve the aiming issue too,
Its a trebuchet because it uses a throwing arm in conjunction with a sling to more than double the throwing leverage within the same space. The catapult equivalent of this would be a handheld wooden spoon.
Great! I love the trebuchet. Built one myself once. It was about 30" high, and with a coffee can full of rocks for a weight, it would launch a tennis ball 40 feet. It was fun and safe for the kiddies to watch. I used a denim sling with super glue around the edges instead of a sewn hem. Worked great. Released reliably. Your flywheel design is my favorite; but the mini is pretty cool. Let me suggest that you add a rifle stock, or another handle in the back so you can steady it better and improve accuracy. It might be fun to experiment with a sight of some kind. Keep on making the entertaining videos!
The best way to prevent injury on misfires is just to make sure you're wearing plate armour. Ball bearings don't do much to good plate and then you'll be suited and booted for the siege
Its kind of weird, that you normally had the very good habit of wearing safety glasses for basically everything, but decided to go for sunglasses in this video.
The counterweight vs. rubber comparison makes it clear that it would be awesome to see the full-scale model have the weight replaced with tones of rubber!
There would have to be a rule that you couldn't just throw the ball bearing by hand, or just throw the trebuchet. Or is it a trebuchlet? A trebunculus?
What a fabulous idea. It makes me long for an alternate universe where gunpowder was not discovered and the 'Gunfight at the OK Corral' was fought with such weapons.
Dude, I'm totally stealing this for a D&D character sometime! It's like the Drow Hand Crossbow of siege weapons! Can it do significant damage? No... but can it deliver a small but potent alchemical payload? Hell yes it could! XD On a more serious note, the stats aren't that bad, but I would suggest comparing it not to a full-sized trebuchet, but to a medieval crossbow. Compared to a 900-lb draw weight medieval crossbow with state-of-the-art cranequin reloading, this thing does, off the top of my head: ~15% range; ~1.2% projectile KE; and at least 300% faster reload speed. ;) Compared to a similarly-styled hand-crossbow? I dunno, I don't know that anyone has made one yet in the real world. New project idea? Considering it isn't yet fully optimized, and you're not pushing the materials to their limit yet, or using optimized materials, I'd say it has promise! As... a totally silly 500-years out-of-date handheld ranged weapon, of course.
The Firearms Act 1968 says you need a licence if it can launch a missile with kinetic energy of more than one joule at the muzzle of the weapon. Tom had this at 0.58 joules, but I'm not sure whether this applies to a trebuchet.
the development of this project is interesting, even if it does not have many practical applications it is always nice to see new ideas and new projects, almost like Ivan Miranda's projects: not all are useful but all are interesting. Go ahead and see you at the next video
As silly as this seems, I really liked it. It's interesting to see that point of "maximum energy transfer" where the armature stops moving still occurs on this small scale. I wouldn't mind seeing a somewhat larger "rifle" version in the ~10 joule range.
When I was 12 I made a miniature handheld catapult, that could fit in the palm of your hand, out of popsicle sticks hot glued together. It used a ton of elastics (never counted how many I used) held by 2 anchors on both ends and wound around the arm until the elastics started to reach their maximum stretch. The tension usually started to bend and break the frames after awhile. The arm was too weak to draw back without breaking so I used half inch dowels for them instead of popsicle sticks. It was capable of launching small rocks like a football field away. Could take out an eye and gave my hands many injuries when something malfunctioned, like the elastics snapping or the anchors spinning or breaking. The strongest one I made was also the smallest because I could wrap each elastic around the anchors 2 times, doubling the power
I think it is more precise to call it a catapult because trebuches by technical definition rely on gravity whereas a catapult uses tension.(trebuches are catapults but not really the other way around)
An in-swinger (Orsova, Hatra) ballista could be fun to do if you're comming to the end of the trebuchet series, there have been some large scale experiments and reconstructions but I'd be interested to see you break down the physics involved and try to produce the most efficient/optimised ballista.
Since it relies on gravity neither to hold the projectile in place nor to swing the arm, you could presumably build one that threw "underarm" rather than "overarm." It might make it easier to aim if bullet drop is causing the projectile to fly more parallel to the topsight rather than at a more extreme angle.
The only logical path forward from here is a drone-mounted trebuchet.
It's flight powered by Leonardo Da Vinchi's flying machine.

You actually inspired me to make a trebuchet with a friend for my final high school project
Did it work out?
the magnet to hold it and the 3d printed cup are brilliant
A curved shield on the back of the mini trebuchet to catch any misfires heading for your face might be a good idea.
