This is genius, I need more of this and less brain rot the algorithm like to send my way.
Aww thanks for visiting! 😁
Why is something like that so much fun to see? Love it.
I know, it’s mesmerizing to watch and I suspect will easily attract a crowd.
Mechanical delay / stepper action / regulator all in one. Amazing. Also probably quite flexible on the timing part. Bravo good sir.
this is what life is all about. You're living it, great video
😮 Wow, you hit the nail on the head exactly. This rat race hamster wheel modern life we live today in the quest for money is not living life. At least for short spurts, I can escape the madness by entering the forests.
I think this is a really great contraption and I'm glad you made this video, I'm definitely going to make me one of these! 😁
My brain needs this!
I have already viewed, commented and thumb's-upped some of your other short videos about this _gravity-escaped-powered_ rotisserie of yours. I find it quite interesting.
I never tought of rotating a rotisserie pole, which appear to be a perfect application !
Same escape principle could be use for a "sun tracker", a small platform that will rotate slowly, to more or less follow the course of the sun, during a day. It was to hold an inclined small solar panel (to optimized exposition throughout the day) or even a beekeeper wax-melting black box with a glass on it... or whatever.
So I would like to comment (try to answer) the little problem you encounter at the minute 28:00. Even though you probably worked it out by yourself, by now...
Anyway, here it is:
Your small cord with a little pouch of rocks at the end to swing it: let's call it "the BALL", OK ?
*1. Keep the force*
Your long white rope exert a force on the vertical shaft, to rotate it 1/2 a circle every time the ball is released. You count on that force to swing the ball to the other pole and to grip it well, spiraling as many tours as you can get. That's the goal, isn't it ?
So, to me, your whole installation appears to be not stable enough. 😢 (You just deposited the pipes onto a rod in the ground, right ? Not sure.) so there is some "loss", there. Whenever the ball is released, the pulling-force supplied by your white cable is -at first- used to "wiggle" (is that a word?) your setup. Or to shake it a little, if you prefer... before eventually rotating the shaft. On every release of the ball, you loose there an important part of the energy that should be kept for the swing itself...
Do you see what I mean ?
Even though it may not be too noticeable to the naked eye, the ball hesitation (slowing up) is a testimony for this loss.
I noticed it, remembering how our ball was just "flying" horizontally like crazy.
Only solution for you, I guess: the whole setting needs to be more solidaire to the ground: Try to reduce the "shaking" by whatever mean you can come up with. Some angular pieces of wood around the rod that will insert into the base of the tube, some butterfly bolts near the ground, whatever... (pouring a cement base would probably be too much 😅). Anyway, make it so the entire force (or most of it) of each release will be fully used to quickly spin your vertical pole, and spin it ONLY.
*2. The swing itself.*
The weight at the end of the swinging rope is not really NECESSARY but for one thing: lifting horizontally the swinging rope. Not more than that. What will actually make your mechanism to stop, until the next escapment, is the rope torsaded around one of the twin retaining-pipes (you already know this). But it's not only the fact that it cause a delay, you get that delay by the grip of the rope around the pipe. So, the bigger the swing, the more turns around the pipe you get. The ball doesn't need to be heavy. Quite the opposite.
Now you will see why I called it "a ball"...
Visualise this: take a simple yellow tennis ball, punch 2 holes in it, insert your rope through the holes and tie it with a single knot on the external end. A ball on a rope.
You have played enough with your setting to foresee the ball will be swinging almost horizontally, due to its light weight, right ?
Thats perfect. It will tornado around the pipe with each torsade as high as possible under each other... and there is no need there for any heavy rock. A light mass just heavy enough to make the swinging rope almost horizontal when it swings is all you need.
Then, as already said, it is the grip of THE ROPE itself around the pipe that will do the job of retaining the whole mechanism not the weight of the pouch. I suppose you understood that already, because your pouch on a first try became a single rock, on a latter version. Experiment a little further and try a tennis ball 😊. It did it, for me.
Wow! What an intricate analysis! Thanks for the feedback!
I like the way you are working out the schematics of the design and bringing us along for the journey. Thank you, liked and subbed🙂
Thank you very much!
This video is awesome. Thank you. I fell down this rabbit hole while trying to build a gyro/shawarma/doner machine for wilderness adventures. Your jerking issue is caused by the direction the weight is spinning off of the wrapping pole. Most designs of flying pendulums I've seen use two wrapping poles on each side. This reverses the direction that the weight unwraps before turning to the other side, making for a smoother turn.
The coating on the pipe is toxic when heated to smoking. I would suggest using other options for the spit. But the rest is fine.
Im thankful for the knowledge and experience to share.
“in accordance with the 1997 Food Code, the use of galvanized steel in contact with meat and nonacidic fruits and vegetables is acceptable. Additionally, the US. Department of Agriculture states, Chrome, nickel, tin, and zinc (galvanization) platings will generally be acceptable for most appropriate applications" (Accepted Meat and Poultry Equipment, Food Safety and Inspection Service Directive 11220.1).” galvanizeit.org/knowledgebase/article/is-it-safe-for-food-to-be-in-contact-with-galvanized-steel
@@davidrogol Galvanized pipes can be safe to heat as long as they aren't heated past their maximum safe operating temperature. Heating galvanized pipes to a red-hot temperature can release zinc oxide fumes that can irritate your throat. The fumes can also be poisonous.
And pipes made before 2014 has more that .25% lead by weight. After are required to be less than that.
@@MrBrandonLindner Thanks for that info. I was hoping to use stainless steel but haven’t found anything I could use yet that is affordable.
It'll be fine.
The best one I’ve seen so far…
im storing this in the brain for future use
This really blew up your channel. Way to go.
I'm definitely going to have to give this a try. I'm glad I came across your channel. I love this type of content
Awesome! Thank you!
The pole pauses as once the rock is released it swings forward and backwards (like a child on a swing) and the backwards part of that swing pulls against the turn of the pole. Having less friction won't change that pause, but having a longer string or a heavier rock will make the pause happen later in the turn.
I see. I’ll have to try that. I also noticed later that it’s important to keep the whole thing level and firm in the ground.
Here's one without any bearings - possibly smoother as a heavier main weight or a shorter arm? ruclips.net/video/pqr7pR3jQws/видео.htmlsi=EHXgZnzySfy6Xech&t=498
I've been using emt conduit for many years to build stuff. Pre-Covid 1/2" was $1.80 at Menard's. Now it's $7.00 . 1" was $6.97, now it's $21.00 OUCH!!
I don't have to buy fittings because I have a MIG welder. I can either weld the tubing together or make corner, tee fittings that will allow me to disassemble the structure.
That welding skill is valuable! Wish I could learn. Makerpipe.com has some pretty cool connectors like quick releases and T’s which make assembly/disassembly easy. 😁 Thanks for the comment!
Beautiful
Thank you!
These were great videos. Just watched the newest one. Awesome. Thank you
☺️ Thanks! I really appreciate it.
We need ADULT LEGOS like this
You could have used the square on the tip of the pipe reamer to tighten the EMT fittings
Wow! I just tried that and you’re right! Thanks so much. Very cool! 😁
If you make the spinning shaft larger it will make your torque greater
I thought of that but it will also let out more rope each cycle, making the weight drop faster. But doubling the weight and using a block and tackle on it will make the weight drop half as fast with the same torque. Increase weight, increase torque.
Using pulley blocks at the weight and the branch will increase your cook time. As long as the rope ends at the weight, each set of pulleys added (1 at top 1 at bottom) should be approx double the cook time.
I just bought block and tackle for this idea. Looking forward to trying it. Thanks!
👍🤠 pretty cool stuff. Nice job buddy.
Thanks 👍
now that is genius. I'm glad you didn't refer your rope as cordage !
Glad you liked it!
Do you do you own editing? This is a beautiful piece (especially the beginning with that classical themed tune playing)! Also the mechanism is really neat. Thank you for the content!
Yes! Thank you!
Great idea and one I feel I'll want to build myself one day. I'm not sure you should be using galvanised steel for the spit part though. I think that might not be very good for you, especially when you heat it up with food. I would go with something that isn't rust treated, steel, iron or even stainless steel if you absolutely don't want it to rust.
Yes, thanks for the warning. Several people have made the same observation. I think I’m just going to revert to wood.
I might add a cap nut to the top or bottom of the pendulum shaft allthread and make the arms easily removable so you can rewind the line on the shaft with a cordless drill, reattach the arms, and get going again in short order!
Excellent advice! Noted! I wonder if I could rig up a hand crank instead of using power tools, just to keep it a bit more period.
@@davidrogol The torque required to raise the weight would be the thing I see as a condition for rewinding the shaft. You could adjust the handle length of a hand crank so you have the necessary torque for the easiest hand-cranking speed and expenditure of energy. The thing about cordless drills is that they have outstanding torque.
One other thing I was thinking about is that most rotisseries rotate much faster than they need to. Off the cuff, I believe one revolution per 30 seconds or minute may be enough. Perhaps you could get 30 minutes or more per load, making reloading less frequent.
Best of luck!
by adding some more pulleys at the weight bag you could make this go even longer like over an hour or so longer
True. I’m experimenting with a block and tackle. 😁👍🏻
This is very cool. Keep up the work. One thing I will say I don’t know if that is galvanized steel or not but if it is you don’t want to heat that to a certain temperature or it gives up gas that is very poisonous and cancerous FYI
Thanks! Yes, I’m switching back to a wood spit. I appreciate you mentioning that. Others have also told me. 👍🏻
This is awesome.
But....
The Gal will release dangerous fumes. Not a problem once its all burnt off but not a great choice of material.
Point noted. I’m going to revert to wood.
What am I missing?
In order to get weights up to top of tree, you have to turn pipe 360 degrees....around and around. Doesn’t the rock swinging back and forth keep the pipe from turning 360 degrees??
You’re correct. If interested in learning about it more then check out my two most recent RUclips videos (not shorts).
I know why the rock isnt working right because i watched your camp site video 😂
28:24 A simple bearing would work
True! I used pillow block bearings in the following video, Hog Hunt Rotisserie
How did you get the numbers? Did you calculate them or you just did trial and error?
What should be the height of the pulley?
The diameter of the wheel, length of rope, the width and height of the pipes?
Actually, I just winged it. 🤣😂🤣
29:29 Dad, I'm starving and this is taking too long! I'm walking to McDonald's - it'll be faster!
Just kidding; this is actually quite ingenious. Will have to try it ourselves!
Thanks! But you still might want to walk to McDo because it won’t be ready for another 8 hours. 🤣
Do you where I could find a picture of Leonardo da Vinci's original drawing for this type of escapement? I've looked for it, but haven't been able to find it.
In hindsight, I think I incorrectly attributed DaVinci for the design, sorry. It looks like the Flying Pendulum Clock was designed and patented in 1883 by Adler Christian Clausen and J. C. Slafter. That should give you some key words for your research. 😁
If you add block and tackle could it slow the weight dropping?
That’s my next trick, or the one after. 😁
You have it timed to where when the gallon of water hits the ground the chickens done?
Once the jug of water reaches the ground, it has to be rewound up the tree like a clock. In this scenario, it was every 24 minutes but I’m working on a way to increase the time. 😁
@ 29:42 did you put a mask around the wheel? Outside of the wheel is blurry, yet look through the spokes, and the scenery is clear as a bell 🔔 🤔
That’s just a result of my masterful cinematography 🤣
Lie the game Mouse Trap 😂❤
I know you bought the pipe but you could call it neobushcraft which is a term I've heard in Bushcraft circles I belong too anyway neobushcraft revolves around scavenging from society or the idea of a apocalypse where you would be scavenge from houses cities etc....
What an excellent term! I plan to make fun-to-watch improvements on the design. Thanks for watching and commenting!
How about trashcraft
Why build it to take up the whole area? Surely you can place the mechanism on the side the weighted bag is. You also do not need the escapement so far away. It a big trip hazard. This can be refined.
Agreed 👍🏻
Nice project. Can a full chicken get cooked around 15mins? Maybe one or two more takes huh?
Once the jug of water reaches the ground, it has to be rewound up the tree like a clock. In this scenario, it was every 24 minutes but I’m working on a way to increase the time. 😁
How long (time) did your 'winding' last?
24-25 minutes in my Hog Hunt Rotisserie but I’m working on a way to extend the time.
Worst recipe for chicken I've ever made. Thank you for your video
😬 Was it my recipe?
@@davidrogol Socks and tape - yuck
Oh! 😂😅🤣 Get wool socks. Tastes like lamb! 😅
You really did "dumb it down". I got so frustrated, I had to double time it
Why wouldnt this work as a perpetual machine since it turns a wheel?
Well, it’s actually powered by gravity. Once the jug of water reaches the ground, it has to be rewound up the tree like a clock. In this scenario, it was every 24 minutes but I’m working on a way to increase the time. 😁
@@davidrogolThank you for explaining that, your videos are very interesting.
Dead over 500 years and he is still taking us to school.
I bet you have to wind that thing back up every five minutes
25 minutes is my record so far but I’m working on a way to prolong it. 😁
@@davidrogol I was counting about 10 to 11 seconds for the rock rope to unwind and the bar to swing to the other sides to start the process all over again so approximately 20 seconds for a full rotation of the rope on that bar. So then you can do the math for three rope turns per minute and then divide how many of a rope turns you had stacked on the tube say 20 or so divided by 3, = 7 to 10 minutes perhaps.
You build one Contraption which I admit is pretty darn cool. Unfortunately that's what all your videos are about. Do you not have the ability to come up with something else? All those other RUclips creators work in their asses off and here's you just skating on by!
Well, I was about to fire up a nuclear fission rotisserie in my backyard but the HOA called the FBI and they shut me down.. 😕
@@davidrogol Awesome answer, you instantly disarmed me! Temporarily 😉
