Trebuchet gets BIGGER! better????

- The trebuchet problem sorting story continues. The ratios of arm length, weight etc were all wrong for what I want to do now so it was going to self destruct. I have now made the arm longer to soften its shaking - will it now throw better?
Oh and I also added smoke grenades to act as tracers.

I know you’re disappointed, but remember: some of us woke up without a trebuchet this morning.
I love the smell of trebuchet in the morning.
But at least I've got the t-shirt... 😉
Hi Tod, does that mean Trebuchet range can be adjusted by release pin angle? If the only suitable placement was closer or farther from the target you can adjust range. Does closer = more impact force or does the shot pick up momentum as it 'falls' so farther is better? Thanks!
@@nowthenzen not sure if you’re aware, but you replied to a reply instead of on the main feed
I love the overlays of the shots at the end for comparison. Onwards and UPWARDS!
Absolutely wicked!
It really is a nice touch.
Yessss continue to do this!
It does make a huge difference in being able to understand the changes in performance due to the various tweaks. I hope the smoke tracers can be improved to make the live shots a bit easier to follow.
"This is the look of a disappointed Tod".
Ahhh poor Tod 😂. Never thought him having a Trebuchet would bring us all so much joy in the end.
Yeah, disappointed Tod looks like many people at their most enthusiastic.

@@euansmith3699 He changed a lot since the early days of this channel. Back then he was very reserved and talked like on a funeral service. He once even said that he is not very emotional dude, but now we see that he can be :)
Torgall - so true. The stages of You Tube Tod.
Just imparting information
Started enjoying it more
I put up a hand rail and had to stand up, people started interacting more and I started investigating more
Got cancer, put on steroids (acted like cocaine) had real fun with Lock Down Longbow (gone now)
Carried on
@@tods_workshop oh dear... cancer has the eery potential to change perspectives (and hairstyles). Hope you've successfully threw it out like a trebuchet!
Think one of the first rules of siege fight club is that the siege weapon is basically never finished.
When I built a 1/5th scale onager as a teenager that thing basically ate up so much free time it became a bit crazy towards the end. I thin it was small mercy when it finally self destructed.
But when it worked it was funny mix of excitement and sheer terror
Do you have the blue print?
I get the same feeling when working on my bokart.
It rarely works well, but the when it does.
best thing ever
I often think about if the impact on my sanity is worth the Scorpion ballista I'm planning on building
Accidentally shooting a bolt through a neighbor's wall is a close second
Come to think of it, writing software is the same thing! Except it never self-destructs so it perpetually sucks up your time.
@@daviddiaz5815 No, I based it off pictures of an 80kg machine which was about 7.5m long, 3.5m wide and 3m tall- then scaled it back to about 1/4-1/5th the size.
(this is also going back to the mid 80s!)
The rest is insane levels of torsion, failure points you never considered and extreme violence
Bear in mind when using bowling balls most of them have asymmetrical cores. It might well affect their flight path.
I was thinking the same, particularly in the episode when Tod wanted to hit the cardboard knights and kept moving them between shots without luck and concluded it must have been the machine's fault. not even considering the possible effects of the wind, the bowling balls themselves seem to be a weird choice considering their superficial homogenity but vastly different inner workings.
and I wonder what the farmer thinks of all that stuff thrown at the field, all the going back and forth and the possibility of weird ingredients of the projectiiles seeping into the ground...
Yeah, the question is, is there a similarly sized dense heavy thing that he could substitute with?
@@Zelmel Maybe footballs filled with a thin concrete and left to cure?
@@Arachnoid_of_the_underverse Yeah, I suspect there's a DIY option, but I was hoping someone more clever than me would have an off the shelf thing to suggest. That's definitely a better option than I'd come up with though!
A custom bowling ball will, but I'm pretty just "off the shelf" balls have standard, symmetrical cores because they're easier to make and use. Professionals are really the only people using asymmetric cored bowling balls, because it allows for wonky ass spins and greater hooking ability that normal people just cant get
Todd the tenacious trebuchet tamer 🤣, love your enthusiasm mate. Keep 'em coming.
Nice alliteration!
Nice!
The comparison shots at the end are super nice to see.
Watching the basket settle down comfortably signaled success. Previously, it was dancing the “Watusi” or even worse, “The Jerk” combined with “The Twist”. Congratulations are in order.👍
Thanks and yes things are better now
Having watched a number of trebuchets at the Pumpkin Chunkin in Delaware USA I learned that the length of the sling plays an important part of the throw. The Yankee Siege Machine being the best example can throw a pumpkin 1700 yards if I remember correctly. But only when the sling is just right. If the sling is too long or too short the shot will be short of maximum range.
I love that this channel has become "the trebuchet channel" recently, it's a lot of fun!
Two things came to mind:
1) I hope someday to find a hobby that makes me as happy as the trebuchet makes Tod
2) Have you thought about having Joerg back again so it becomes a repeating, self loading trebuchet? Gatling trebuchet!

@@MonkeyJedi99 Huh, I'm a Tolkien fan, but this level of detailed knowledge worthy of Colbert always amaze me. My hat is off to you, sir!
@@JesusVillalobos (/bow)
I think that those videos are so much fun, and only 75% of it is that Tod is soooo into it and that makes me excited to watch it all too hahaha
Love it when someone spreads positive energy.
Glad you like them!
Trebuchet 💓
Man I thought that first shot looked great but then the second one went and my jaw dropped! Excellent work!!
I love this series. I almost look forward to oversights because the refinement process is presented in such an engaging way.
That's just so cool. It's amazing that people were making these back then. Truly astounding.
you sir are an absolute legend, keep up the good work
Thanks
Loving these trebuchet videos! Keep em coming!
Thank you for including the illustration at the end.
That's one awesome machine. Todd you're the man
Some improvement and it was interesting to watch as always
There is just something special about watching medival style engineering work in action
The overlaps shot at the end was brilliant.
Beautiful overlay at the end
Thanks
Oooooooh! I LOVE the trajectory graphics!
Long time fan and absolutely love these trebuchet videos, also supported you by getting a sweater from your shop :)
Nice to see Mk III working almost as intended. Well done.
i LOVE the trebuchet stuff, Tod. keep making good stuff
This makes me miss my trebuchet.
Great job!
What is preferable, to miss your trebuchet or a trebuchet to miss you?
I quite like getting missed

This was my dream as a kid, I had one made with a bunch of 2x4, some dowel, and a large paint drum. I had no idea how to make a release mechanism though, so that was just an ice cream container, making it half catipult. That was a lot of fun as a pre-teen, but this is just awesome.
Tod's trebuchet has a better upgrade path than most video game weapons at this point.
thanks for the comparison at the end! I know is "extra" work but they look great
What a great channel. Tod's excitement really comes through :)
I hope we get a video that is a call between you and someone who specializes in building/designing trebuchets about the physics and design ideas and what you need to do to yours given the parts that are easy to change and the parts that are hard to change.
I recall vaguely from building a 1 meter arm trebuchet as a kid that the goal was to balance the weights until the arm basically stopped moving entirely when it released the payload.
I lobe these trebuchet videos, and I just can't shake the feeling that the knowledge gain from these videos is somehow going to be used in my military career
Surely only if you also have a time machine
For when the aliens send you ack in time or to some fantasy Realm?
When you're shooting all the way into dusk, a flare might be a better choice than smoke. But it's of course much more dangerous.
Check out Tod's Flaming Trebuchet vid
This could be a series: Trouble Shooting Trebuchets
This lad is living all kinds of childhood dreams 💪🙏
From the 'previous shots' footage compilation it can be seen that a release angle of closer to 60 degrees gives a further shot than that of closer to 45 degrees.
Physics would decree that an angle of 45 would give the most efficient release angle for the furthest shot throw.
However the effect of wind resistance, especially when the shot ball is moving at it's greatest velocity at the start of it's path, transfers to reduction of initial velocity and thus initial height gained.
Therefore increasing the release angle to closer to 60 throws the shot ball to gain greater height to allow it to have an extended path which in turn allows a greater distance to be gained by the shot.
Great work Todd. I watch all of your and Matt E's uploads religiously, and love them.
Cheers, Mic Barrett
Thanks Mic, but I not a physicist, but I suspect at these low velocities, wind resistance doesn't have much to do with it
@@tods_workshop
You'd be surprised.
But on the angle of greatest efficiency it's easy to see even with common sense that that's right.
And wind resistance is the only other external force, the only one.
Gravity is accounted for in an ideal system ie. with no air-resistance.
Not blowing my own horn, but I am a physics teacher. But honestly, physics is only a whole lot of very common sense.
And thanks heaps for all your effort, and a great show.
That last shot ! Beautiful
Brilliant. Thank you again for sharing this coolness!
Thank you for showing all the trajectories at the end. God bless and stay safe.
I mentioned missing the composite end shots in the night firing video. I really liked seeing the all the data at the end of this one. Thanks!
I'm blown away! I'm seeing into the past through this! 😳
Great stuff Todd. My son bought me a wooden model Trebuchet a couple of years ago and it is great fun. Keep up the good work. Flaxen Saxon.
I have a minor suggestion Tod. I love how at the end you add in that line that follows the shot and we can easily see the trajectory, but do you think you could leave the line onscreen after each shot, maybe make them different colors too, so we can see all the lines at once?
Thanks and I will try and find the 'best way'. I think it is a really powerful tool so will try to make the best of it.
Kewl. I remember having to make one of these when my son was a Scout. We had four teams and worked together as a team to build it. We launched melons. Good times. We surprised ourselves with the distance we achieved.
Good stuff.
Excited Tod puts a smile on my face
Thank you , Tod .
🐺
Awesome Tod, looking forwards to the next update!
Loving this series!
i love this series keep it up
Ahh! I really enjoyed showing the shots in color on the screen. It helps my aging eyes!
I like the tracking graphics. I wish I new how to do that.
Great stuff. It definitely sounds 'happier'.
Yes it does and I am much happier too because I can now believe I will have it in three months
Can't wait to see more trebuchet action!
Are there any ancient manuals on field running trebuchets? I can only imagine this is encountered with every trebuchet assembled.
I don't think so
Had volume all the way up during that intro...
I have a friend who's a real stickler for grammar and spelling. So as I've talked to him about seeing these videos, and wanting to own my own terbuchet, I been pronouncing it as "tray-bucket". Watching the resentment on his face never gets old.
Trebuchets: Debugging, with physics!
That machine is doing better than Age of Empires 4. 😄
The number of parameters to adjust on this is fascinating - it's far from a simple thing to tune. Very reminiscent of cartridge development - powder type, burn rate, powder load, bullet weight, bullet shape, barrel length, primer type all come into play
Or infuriating. Yes there are lots of variables and some have a bigger effect than others, but every one interrelates. I am beginning to form a theory though which is handy.
@@tods_workshop Lovely to watch - when it's someone else who has to solve it 😁👍
Thank you..
I'm really enjoying this series!!
The mathematics are fascinating. It would be interesting to use some kind of physics software to calculate the differences by adjusting all the variables - lighter ammo for example, would it go further and with more energy due to increased speed, how much weight has to come off to compensate for the extra load in the extended throwing arm, what if it releases a millisecond earlier, all super interesting.
I paused on the overlay at the end, interesting shot!
Excited for the next video. Good luck!
it should be pointed out that, the range is one thing, the more important is the flat trajectory.
to slight a fortified wall, the energy transfer of the projectile is the key, not the distance per se.
cool as always Tod
Yeah... U can see with the overlay at the end.. the other ones were letting go way sooner... Much Better launch angles... I think ur right... Shorten up the rope a bit... And it will fling at a higher rate..
But I don't have one.. so I don't know exactly
3:04 disappointed Tod
3:21 appointed Tod
I love the learning aspect of this, like it's such a niche thing that people havnt really thought about for more than 500 years.
I think if you dig down there are far more people than you think
Check out punkin’ chunkin’. Happens after Halloween in Deleware, I believe. Catapult, air cannon, and yes: trebuchet. Those people are nuts!
I'm loving these trebuchet vids
The bucket jiggles because you've got it mounted flat on the ground. Trebuchet designs were almost always on wheels with a bit of play back and forth, and that force in the bucket transfers to the base, so instead of the bucket rocking, the whole thing moves smoothly forward and backward from the same force.
People keep saying this, but actually do we know this? I am not so sure, so can anyone provide good medieval drawings with them on wheels; not fanciful ones.
Tod will corner the market on rental Trebuchets
There was already a video about the accuracy of aiming. I found the idea with the "bowling" targets quite funny. What if you tried it with a kind of grapeshot, maybe with a big bundle of plumbata as ammunition.
Once he has settled with the tuning redoing that video might actually be interesting too, maybe it delivers energy into the projectile more consistent now and he did that V gutter illustrated at the start (should guide the projectile as it gets pulled initially).
Maybe the lucky immortal enemies will not be so lucky anymore! Oh and uhhh grapeshot suggestion sounds like an invitation for Tod to take out multiple cameras in one shot with his luck.
What's really funny to me, is that even the "disappointed " Todd sounds and looks sooo amused and happy cuase he can play with the trebuchet.
I envy you!
You are right. "Disappointed Tod" still has a good time
Love a good trebuchet, good to see the machine looking happier.
Could it be the extra mass and leverage of the extended arm is absorbing the energy from the basket without any additional transfer to the projectile? Calmer basket but with no more range?
My thought exactly, and I’m sure you can work out the acceleration difference between the original and 1.2m longer radius with the extra mass but I can’t be bothered right noe
Add wheels to the thig. It helps both with both distance and stress.
2:00 - it's nice that the trebuchet has a built-in toilet.
Another trebuchet video… Today is going to be a good day!
1:52 in true medieval fashion he has the really clever engineering down but the actual accurate numbers and scientific preciseness of it is out the window lol "I don't really know!"
For your smoke tracers, I'd like to suggest reaching out to the channel Ordinance Lab. They're properly licensed explosive experts based in Texas whose whole channel is about doing fun and wacky stuff with explosives. Helping you find a UK-legal, relatively safe way to generate a lot more smoke from your projectile would be right up their alley.
When the thumbnail shows a man holding aloft a purple smoking ball you have to tune in. Especially when he's wearing a hat which wouldn't shame Baldrick in Blackadder I.
smokin' balls
@@tods_workshop New video title!
You get it to the point it is throwing a good distance consistently and all will be good in the world.
Brilliant stuff
i like the way he explains things. Makes me happy and makes me laugh hehehe😂😊
You're just a LEGEND....... building a f*cking trebuchet...
Congratulations for your work, "Todbuchet"
Todd is the embodiment of using your engineering degree for what you want to do and not just for a good career
Just to be clear I actually got a business degree
An other way ow dealing with the energy dissipation problem would have been to reduce the energy the system has to deal with by adjusting the counterweight. I love how reducing the energy was not even worth cosidereing and instead you went to enable the system to deal with the energy it has. We need more power! :)
Absolutely!
I TOTALY BOUGHT A SHIRT!.... Great video!
Thanks - appreciated
When you've finaly figured everything out, will you then tackle a Castle or fortified Town with your "Jawbreaker"?
Tod, awesome work mate! When I was testing my potato cannons I used to put a mini glow stick in the potato "slug" and it looked brilliant at night! Not sure would work with a bowling ball, but might be worth a try for a night shoot? OK, or just greek fire! Nudge, nudge, wink, wink :)
Recently discovered your fantastic site. Bought a trebuchet t-shirt to support the site. Would *love* to get the "fastest way to a man's heart" one but it needs to be in a woman's cut and not in a boxy man's cut. Hopefully, that becomes an option sometime in the future with your supplier.
Thanks and hopefully. I should be opening a page on my site soon that will make things easier
Fascinating to think that the armies that used these machines didn't have computers to work out how to use them.
it must be because they created the machine themselves
I wonder how must it be, to be your neighbour sir.
Hearing "Loose!" and just cover in fear of bowling ball smashing through my window :D
(I know you have it under control and everything, but still :D )
Sometimes old school is best!
For chasing accuracy, take a look at around @4:13 - as you yank the trigger-rope, the end of the arm moves a lot sideways (maybe a foot?). Could you modify the trigger to either release more easily, or else re-direct the trigger-rope in such a way that it pulls 'down' on the arm, rather than sideways?
I still think that a big basket with hand sized stones would be the most likely weapon against infantery. I am sure our ancestors knew how to release them at the right point to create a deadly swarm - also in different distances. The trebchet was likely used downhill in areas with a lot of natural ammunition - and against fortifications where the distance to the enemy didn't change much.
It is all fun and games until someone in the next village over loses their chimney. That t-shirt is very cool.
“Then comes the end of the fixing”
Yeah, RIGHT, Todd….
I know. Ever the optimist. As a knife maker trying to make a living being an optimist is essential
The longer arm appears to need a slightly heavier counterweight.
