opposite of silly, really. only really useful with a group. 20 to 30 min is a lot of time to do other tasks. then again, bury the food on coals, right?
I think it would be a fun project that could keep me alive if I were in a survival situation. Not the spit itself, but the something to put my mind to and the feeling of accomplishment having built it.
This is exactly how a mechanical clock works - the weight is replaced with a spring, and the "spinning" stick is replaced with a flywheel. Very old grandfather clocks indeed had weights hanging down that powered the flywheel.
Heh, I just said basically the same thing. I brought it a tiny step further, and debunked this as a DaVinci "invention" based on the fact that the weighted clock was invented 170ish years before DaVinci was born. He just repurposed the tech to spin a stick instead of clock hands.
In a scenario where I'd be living in a permanent camp I'd do this but it seems a bit too much work if I'm gonna be somewhere temporarily. Also, sitting by the fire and turning the meat over yourself has its own charm.
Yeah, but sitting there turning the meat wastes a lot of time. I guess it depends on how established your camp is. I'm thinking that while this meats auto turning you could completely restock the wood you just used for the fire.
If you turn the meat all over yourself you'll end up pretty greasy I would not recommend it. Especially if the grease is hot, you could burn yourself. Safety first.
I mean, perpetual motion doesn’t exist. It will run out of energy due to frictional losses much sooner than with the hanging rock falling due to gravity. Just put more and longer restrictions in place and it will last longer
@PayterX I dont think you understand what they're saying. They aren't describing a perpetual motion device. They are describing an easy-reset mechanism. You just set up the pulling string on the other side of the spit, then when your rock bottoms out, you simply move the rock to the other string, and it runs the entire process in the other direction, which causes the first line to reset itself. It is not a perpetual motion machine because it requires human labor to reset the kinetic energy that powers the device. It is just quicker and easier than having to manually re-wind the string every time the rock gets to the bottom.
I was thinking something similar, only loop the same rope back to the bottom of the existing “timer” post. Same idea just using one rope. I’d be interested to see if either or both of those ideas work!
@@ardgeighw5174 late reply, but yes you are most likely right. I probably misunderstood it, being as I often see people proposing elaborate perpetual motion schemes
Forest survival games don't tend to have 50 feet of rope, and when you are starving to death, making a bunch of grass rope isn't high on the priority list. Shit, even if they had the rope they don't generally have food. Certainly not enough of it to invest the time and labor into making an automatic rotisserie.
This is a very amazing and clever idea. It reminds me of some stuff you would see on gilligan's island lol, thank you for sharing.I will definitely be trying to build one of these on my next camping trip
If the line that goes to the big rock leaves horizontally it will even out the force coming from the escapment mechanism and won't be pulling the spit up off the supports. You can do this by redorecting the rope arpund a pulley or smooth branch. The sticks you added increase the diameter of the spit meaning it will spin slower but with more torque, this worked well and could be amplified by using bigger sticks or by having a smaller diameter on the virticle entrapment stick. Great build, bravo. Would be fun to do on a large spit roast pig or lamb for a party
Yes, but it would not slow down the rest. So your chicken might turn a lot slower, but you won't get more time out of it. If you want more time and turn the chicken slower, make the spinning pivot thinner. It can only release however much rope it takes to make a half turn, so by making the pivot thinner it's releasing less rope. The rock comes down slower, the spit turns less.
the diameter of your spit and the vertical spinning stick will give you the "gear ratio". so adding the extra twigs on the stick also helped achieving the desired "roasting" revolutions 😁
That's correct, but using a thinner vertical spinning stick would not only slow the spit rotation, but also slow down the descent of the big rock. Really, the main question is: how much rope do you want to release on every half turn? Once you know that, find a stick (desired half turn slack * 2) in circumference.
If it is "overpowered", you can whittle down the stick where the rope is wound. This lowers the torque proportional to the diameter change, and increases running time (total turns).
I don't know what he uses(looks like oak or ash tree) but often fast growing trees are straight when they are young. eg. Robinia and hazel nut grows straight as well. Mostly the new shouts from an older busch.
i was thinking the same, where I grew up even beech tree was rarely straight without knots turning direction along the length, and now I'm near an oak forest it's even worse. feels like living in canada is the ikea version of bushcraft rofl
Neat construction, theoretically if the rock builds up enough momentum to be caught properly you could make it more efficient by using four "braking" sticks rather than two and double the time the rotisserie operates, the two extra sticks may not even need to be braced, just driven into the ground.
If you did this again, could you skip de-barking the posts the rock wraps around? And instead of boring any holes could you use two crossbeams and lash a square to hold the twisting post? And maybe with a rock pile to anchor the rotating base? Did the rope try to yank the spit towards the tree or was that not an issue? VERY impressive project, Leo was ahead of his time!
I subscribe to Felix, but I guess I missed this one. Great build, it just looks fun. Just need to figure out a way to not trip on it when I get up in the middle of the night to pee.
I'm imagining the next version with a lever at the bottom of the big rock that releases a stream of water to put out the fire and drop another rock onto a bell to tell you it's done ;)
He didn't invent this. The weighted clock was invented 170 years before he was even born. He just made a weighted clock, that turns a spit instead of clock hands. For real, with just a few more parts this could literally be a clock.
Ok so if u do 4 post in stead of 2 wouldn't it slow it even more also variations of length of the swinging rock rope could vary rotational then you could also do pulley for
Why not have a mechanism where when the rock hits the ground, it tips a bucket that puts out the fire so it doesn’t burn on one side if you forget to reset it
They say that in a survival condition, it's wise to keep busy. So, your water source is good, shelter built, firewood gathered, broken to size and piled nearby, traplines and fishing lines set. Whatever shall i do now? Oh wait, i have an idea.....
You gotta reset that big rock a lot ey? What if you added two more upright sticks for the small rock to spin around basically making it do a quarter turn, instead of a half turn
very interesting and kind of useful, useless in a survival setting, more like a cool build to do when camping... but the materials required are a little too much, but who can complain, you escencially make a mechanical rotor, powered by a gravity battery and timed by a mechanical controller.
Hey can anyone tell me what would i need for my kit for staying a forest for at least 2 days? (I have a helikon tex racoon mk 2, Polish unirofrm and a helikon tex gaurdian plate carier) can anyone tell me what can i add to my kit/setup?
Thank you! Having this knowledge and my actual practical skills, this project will take approximately three days. Day 1. Collect all materials. Day 2. Figure out why do I have so many useless and no most important. Find them. Day 3. Build, hold on tears understanding that need to catch something for cooking. Eat one can of SPAM. Get back home. Tell my family the story about Da Vinci helping me to survive in wild and how much fun it is. Next time lets do it together with your new guru.
No it wasn't. The weighted clock was invented 170ish years before he was even born. All he did was repurpose the tech to turn a spit instead of clock hands.
Why do people keep acting like this is some major build? You need 8 sticks, 2 holes, 1 big rock, 1 small rock, and some rope. It shouldn't take more than about 20 minutes to build this. Most of it is just shoving sticks in the mud. Really, the only part of this build that is a little hard is making that dovetail, and customizing a stick to fit in it perfectly.
not sure if you've done one, just posting here b/c thid is one of your most recent. YOU SHOULD DO A CHRISTMAS TREE TO TOP OF CAR video incorporating trucker's hitch and taut line hitch. If you showed both ways (for someone with car rack, and someone without) think woulf be great christmas themed video would probably get a lot of views 🤷♂️..just my two cents
A fun one to build with kids/scouts, or just give yourself a fun DIY project !
Thanks Leo!
😂
this seems like a great project to show children. The silliness of the whole thing entertains while the physics involved educates.
opposite of silly, really. only really useful with a group. 20 to 30 min is a lot of time to do other tasks. then again, bury the food on coals, right?
The "silliness."
How ironic. 😅
Just got to make sure the none of the children get clocked in he head by the stone flail part.
So if you get whacked unconscious by that spinning stone, by the time you wake up, dinner's ready. 👌
But you definitely won't have an appetite with all the concussion nausea and worse from a head injury like that 🤕
No you're missing the genius, it's fighting off predators that came to investigate the smell of roasting chicken 😂😂😂
And that is how you make ye old'e instant meals 😂😂😂😂
really appreciate you showing the spit working and how it works before going into the entire build...
I'll starve to death before I finish building this
Just think how tasty the meat will be, after you spice it up, before you build that? 😮😂
Natural selection
😂
you can always eat the chicken raw
I think it would be a fun project that could keep me alive if I were in a survival situation. Not the spit itself, but the something to put my mind to and the feeling of accomplishment having built it.

@@0neMadGypsy He probably just got bored during a field trip then built this.
As a scout i find this educational
Thought so too. Greetings from a fellow scout(Austria).
Thanks for bringing this renaissance genius into bushcraft where more people can appreciate him and his engineering. Nicely done!
Cant believe leonardo dicaprio liked Chicken so much he invented turning it... Crazy world
By the time the chicken is cooked his date will be too old for him
That is pretty slick. I hope some people will try this and it works good for them.
Excellent! As a former Scoutmaster,I have seen many camp gadgets but this is amazing!

I’ve seen this technique before and you’ve done a great job showing how it can be done. Thanks for sharing it.
So much fun! Love Felix's channel.
If you make the mechanism 2 sided you can just move the rock back and forth, and you have a self re-winding mechanism.
Ya that’s a really good idea, you’d just have to switch the connection between the rope 1 and 2 which is simple. And life the rock.
I mean, perpetual motion doesn’t exist. It will run out of energy due to frictional losses much sooner than with the hanging rock falling due to gravity. Just put more and longer restrictions in place and it will last longer

Forest survival games have been sleeping on this!

Shit, even if they had the rope they don't generally have food. Certainly not enough of it to invest the time and labor into making an automatic rotisserie.
I love things like this. I'd love to see more bushcrafted contraptions in the future!
This is awesome! If I'm not mistaken, this is what they call an escapement mechanism like what they use in clocks.
This is a very amazing and clever idea. It reminds me of some stuff you would see on gilligan's island lol, thank you for sharing.I will definitely be trying to build one of these on my next camping trip
It's a weighted clock that turns a spit instead of clock hands. If you want to make it better, look into how weighted clocks work.
The escapement is so impressive! Love this concept
What a kewl useage of the auto rotating spit! Thank you for showing this!
Always a pleasure to watch your videos ! Started with the basics knots, seeing them in practice is great ! 😁
Great example of applied bushcrafting skills. Hats off to you sir!
Liked + subbed for more great outdoor content!

Absolutely fantastic 👌
That looks really fun and satisfying to build. I think increasing the stick bundle's diameter on the end of the spit would slow the rotation.
Yes, but it would not slow down the rest. So your chicken might turn a lot slower, but you won't get more time out of it. If you want more time and turn the chicken slower, make the spinning pivot thinner. It can only release however much rope it takes to make a half turn, so by making the pivot thinner it's releasing less rope. The rock comes down slower, the spit turns less.
That is what I expect to see in an episode of Gilligan's Island. It even looks like a zany contraption. Only yours WORKS for real.
What are you trying to say - you can't make a radio out of a coconut and some sticks? Don't come around here shattering my warped sense of reality. 😂
the diameter of your spit and the vertical spinning stick will give you the "gear ratio". so adding the extra twigs on the stick also helped achieving the desired "roasting" revolutions 😁

If it is "overpowered", you can whittle down the stick where the rope is wound. This lowers the torque proportional to the diameter change, and increases running time (total turns).
Hahaha, now that is pretty fun. Thanks for sharing.
this guy proof how to implement physic on your hobbies
Thank you for sharing this.
Put the weight on a block and tackle to get more time out of the height.
Thanks DJ! 👊🏻👍🏻 God Bless 🙏🏻 Appreciate you always my friend!
I’ve never seen perfectly straight sticks. What type of tree produces them?
The stick tree
Oak saplings grow fast and high. But not always
I don't know what he uses(looks like oak or ash tree) but often fast growing trees are straight when they are young. eg. Robinia and hazel nut grows straight as well. Mostly the new shouts from an older busch.

Poplars can
Great job!👍👍👍
Perfect job 😲 👍🏻💪🏻
Nice job!
Wow will try this
What a cool way to make use of physics 😅
A smaller version of this mechanism can be used to make a timer for spring traps
Neat construction, theoretically if the rock builds up enough momentum to be caught properly you could make it more efficient by using four "braking" sticks rather than two and double the time the rotisserie operates, the two extra sticks may not even need to be braced, just driven into the ground.
pretty cool . how did the chicken turn out lol .
Génial ! Merci pour cet excellent partage Il ne manque plus qu'une bonne bouteille de vin pour accompagner ce poulet, une salade et du bon pain ;-)
So cool!
Very Nice 😎👍
That red rope is unreal.
Thats pretty much a smal clock ... a clock mechnism bust still awesome :D
I think you can add more veridical sticks for the rock to wrap around.
If you did this again, could you skip de-barking the posts the rock wraps around?
And instead of boring any holes could you use two crossbeams and lash a square to hold the twisting post? And maybe with a rock pile to anchor the rotating base?
Did the rope try to yank the spit towards the tree or was that not an issue?
VERY impressive project, Leo was ahead of his time!
Would love to see somebody use this on the next season of Alone. 👍
Wow! Cool!
I subscribe to Felix, but I guess I missed this one. Great build, it just looks fun. Just need to figure out a way to not trip on it when I get up in the middle of the night to pee.
Once you have all the parts made, taking it apart and putting it back together when you need it shouldn't be a big deal.
I wanna go camping now!
Awesome love it
Four sticks, instead of two for the escapement mechanism, would slow it down much more.
Or just use a thinner stick.
all that, to mess it up cooking over open flames so the chook gets burned lol
Awesome. It could run indefinitely if the rope would form a belt which is powered by a water wheel/turbine
If you copy the rock weighting system on the other side and hang a lighter rock in there you could let it wind itself back up, just swap the rocks.
I'm imagining the next version with a lever at the bottom of the big rock that releases a stream of water to put out the fire and drop another rock onto a bell to tell you it's done ;)
Cool!
I’d love to build this but I mean, we’re already out camping using our hands doing things manually… I think I’m good turning it on my own
Hi, im new. Thanks for making this
Probably redundant to say this about anything old Lenny invented, but I'll do it anyway. GENIUS!
He didn't invent this. The weighted clock was invented 170 years before he was even born. He just made a weighted clock, that turns a spit instead of clock hands. For real, with just a few more parts this could literally be a clock.
Спасибо!
That's a cool looking contraption but it takes more effort to setup than is actually saves.
this has to be put in survival games as a buildable structure ahah
Gears wold make this so much simpler.
This is also how a wind up watch works
Nah, it's definitely a weighted clock. If your watch has resettable weights in it, it might be time to buy a new watch.
@0neMadGypsy the idea of an escape that bleeds of energy lol
How'd the chicken turn out 🍴?
hey whats the name of the background song with the flute? It's very soothing
people in 1500s : damn robots takin' mah' job
Ok so if u do 4 post in stead of 2 wouldn't it slow it even more also variations of length of the swinging rock rope could vary rotational then you could also do pulley for
This could be used for so many things. I think I'll build an automatic loom in the wilderness 😂
Why not have a mechanism where when the rock hits the ground, it tips a bucket that puts out the fire so it doesn’t burn on one side if you forget to reset it
Where are going if you have Made that tool ?
My Grandmother had a clock that worked on this same principle.
se puede hacer un reloj o aprovechar d muchas maneras la rotación, yo lo hacia cuando era scout
Genial.
Excellent video. And that looks delicious!
May I make one suggestion?
Increase the thickness of the cage. Between the pendulum and the weight!

It's basically a primitive clock escapement
If you had 3 legs for the frame it would stop 3x a revolution. More even cooking and a slower drop.
Is way cool though

That is pretty cool but not needed. BUT I like the way you are thinking
This was invented by Leonardo da Vinci, born1452, died 1519.
No it wasn't. The weighted clock was invented 170ish years before he was even born. All he did was repurpose the tech to turn a spit instead of clock hands.
Damn just throw the Chicken on the fire 🔥 🍗 😂
Is this honestly less work then just turning it every minute or so
Dad, can we just open a can of pork n' beans for dinner? We're starving!
Hold on sweety. The auto-spit is almost done.
But dad, its 2 a.m.!

For all that work wouldn't it be prudent to just do by hand? Unless you n are in a cottage location 🙂
why i just thought about homer simpson strangelin his woodpeckertoy for not preventing the nuclear explosion of his powerplant?
100x easier and faster to just turn the chicken yourself!
