- A follow-up to my previous video. I wanted to show my basic process for creating the mechanism so others could try it themselves. If you'd like to see an in-depth tutorial on creating gears in Inkscape, let me know!

Fun fact: If you were somehow able to turn the gears in reverse and slowly turned the last gear only 90 degrees slowly over one hour, the first gear's outer teeth would be moving at 2.16 times the speed of sound. That's assuming the gears are 2" in diameter.
big brane
Damn
Made a joke comment a bout this but the fact of the matter is the amount of kinetic energy required to make that happen would tear the gear system apart long before you got there.
Just build it out of tungsten
@Blender Rookie and with the torque you need to do that you could pull the earth against it's Rotation...
Kinda wanna build this and put a small motor at the end spinning at some fixed RPM so that it rotates the last gear once every year, hang that on my wall and bam, you got a clock for the year.
@Internet Gamer'z 360 Promote your videos, just not on other people's channels. Create an instagram, a facebook, a twitter, whatever, and promote yourself there. But don't prey on other people's fame, that's as low as you can go in terms of promoting yourself.
@Internet Gamer'z 360 this isnt even your targeted demographic lol
Hey, what time is it?
About November.
this comment section was uhh............
@LaCrak 27, dude, you are not getting recommended any time soon
So it was true... Spinning the last gear will destroy time and space!
Yep that happened to my universe im the only survivor
@Internet Gamer'z 360 Do you know how annoying it is when someone puts a link to their own video with absolutely no context on a completely unrelated comment?
@@maxtes252 no.
Its confirmed
It can't be reverse because you'd need a lots of power spinning the last gear.. did I get that right?
That's pretty crazy, especially the cast into concrete one.
wHAT DOES that prove?
@@David-rj1ru The gear reduction is basically infinite. If you have 1 end cast into the concrete, then that end isn’t moving at all. Yet the other end is, so the reduction is massive.
@@TonyTheTruckGuy thank you, I didn’t get that part
I remember this guy made one that would take longer than the life of the universe to turn
@@jwalster9412 Insane to think about haha
The clock in the front of the class-
Underrated
underrated lmao
Fear not. The ratios are suddenly reversed once you're out of school.
Sacred clock
@@aviandragon1390 nooooooo
Me: *_So if you spin the other end..._*
SPEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEED and no torque
@@thiccfrogg1380 DEJA VU !!!!
It would require more energy than there is in the galaxy but yeah, SPIIIIIIIIIIIIIIN
Gone, reduced to atoms
lets say other gear will move v^6( idk , but let say gear diameter is 10 cm and radial speed is v = l/t so l equals about 32 cm , and realise that spins 60rpm and then that equals =1,073,741,824 meters per second ( radial speed ) ) , and then realise you mount that into a car transmission ........
Car : ...---...
With this kind of ratio, an ant could probably power an elevator shaft.
Easily. But the shaft woudl take years to cover inches, because insane increases in torque seem to bring insane decreases in power.
eventually
it's a cool thought, but it would probably take a few years just to get rid of the free play in the gears
No, ant doesn't have enough calories
@@anant6778 decrease in "speed" not 'power'
So this is one of the videos that’s gonna be in everyone’s recommendations and has a few million clicks in about a year right?
Yup.
Probably. You should check out a guy who did this with legos.
Oh no my friend, this is in everyone’s recommendations now

@@ReymonG90 thx
As far as I can tell, there's about a 1 in 74000 chance that you happen to click on his channel within 5 minutes of him posting, assuming you clicked on it perfectly randomly.

our world needs people like this who are interested in this kinda thing
in a few thousand years, that concrete will crack
The creator of the model with the last gear encased in concrete, Arthur Ganson, has this to say: "With the motor turning around 200 revolutions per minute, it will take well over two trillion years before the final gear makes but one turn."
@@royfinktum8484 it won't take a full turn to crack the concrete though, maybe 1/20th of a turn.. but still.. that's several billion years so still have time to spare..
hey its still better than my download speed.......
@@shadowproductions969 1/20 of 2 trillion is 100 billion. Given that the universe is about 1/7 that age, I think that sounds like several.
Mind blown on the concrete demo. I wonder how long before all of the play in the system is used up.
according to one post, 2 trillion years for a full rotation.. so assuming several billion years before it turns enough to break the concrete.. the concrete will have long crumbled not to mention the drill turning it.
This the type of video to blow up in 7 years

Amazing! I love this sort of stuff. In my next life I want to be a mechanical engineer. I looked at an old typewriter and was Impressed that it was made using a slide rule. Thanks for doing this.
I find this interesting. Like you said, it's cool how at one end, it can be going so fast, while at the other, so slow.
I’m amazed that you still have that DeWalt from 1994.
They’re having amazing black deal specials in case you want to upgrade!
Nice advertising you wont get me though/j
@@seanharvey1250
Modern tools are literally an order of magnitude more powerful than this one.
Thanks James Spader, very cool
Everybody gangsta till last wheel starts spining and collaps the universe
Rare to see recommended videos without ads nowadays, good to see one like this
On a bicycle that has 21 gears the smallest one enables you to ride up a 45° hill
Yes but do your knees enable you to ride up a 45° hill?
the biggest problem with gear reductions and my big problem with 21 speed bikes.. while it gives you a huge advantage in torque, you have to also multiply the speed.. so if you reduce the torque needed by 10, you have to multiply the speed by 10 to keep the same speed you want at that lower torque. It's a lot like electricity when stepping up and down voltage.. you either step up voltage and lose amperage or step down voltage and gain amperage. or PSI and GPM in water.. most things have an inverse reaction.
@@shadowproductions969 not most, all things follow the law of conservation of energy. You put the same amount of energy into climbing uphill regardless which gear you use, it's just a matter of power/torque trade
Or you could just strap an engine to it....
@@shadowproductions969 well, yes. But the logic is that you will go slower but also it will take a lot less force to go up the hill, albeit at a lower speed

Holy shit I just got your other video recommended, and now new video uploaded 6 mins ago
These type of videos keep getting recommended to me and now I’m a gear nerd
Hey you should try a pop filter/better one on your microphone. Love the content keep it up!
This is made of wood? That's amazing. I had a car made of wood years ago, wooden engine and wooden gearbox, wooden panels, seats and wooden dashboard. Trouble was it wooden start.
If it had a computer, you should have checked the logs.
@@SomeUncomm oh, leave it out 😂
466 days to rotate the last gear, if the first gear rotates at 100 RPM
That's what I came up with too! Thanks for confirming!
127.68 rpms to output 1 rotation per year
2+2=4 that’s what I got.
@@tweekachu2605 holy shit dude, how can you be so wise....
@@apatriot6421 it ain’t an easy life but someone’s gotta live it.
Stole that quote from Garfield.
that last gear might take 1.5 years to turn but you AINT GONNA STOP IT
It would be kind of interesting if someone set up an automated livestream of this type of thing. That way we could watch for an extended period of time.
This is really interesting! Would love to see more about this. Especially the physics behind it and whats possible/not possible to do
He sounds so nice, must protect.
That museum exhibit blew my mind. That thing looks like a grenade waiting to explode
When you watch a video on high gear ratios and your recommendations is then filled with them.
Here’s a thought: a huge gear reduction, and the the reverse at the other end. Will the output gear turn, and will it turn at the same speed?
Would probably take a long time to use up all the slack from tiny imperfections and wiggle room and compression of the wood.
theoretically yes, realistically no, like hi Barr said. If you did this on a much smaller scale it might be more feasible.
I would love to see a more polished version, maybe with the last gear apart from the others so its more visible that that is the last one. And out of clean metal.
Hook the other end up to a lever and a Bucket. Fill the bucket with water, and attach a fan blade to the first end. It might work better with a Pulley system(and definitely less gears) but electricity-less fan.
Try spinning the last gear and see how has it spins
its impossible
Bruh he literally said in the video it’s impossible
@@squidwardstesticles5914 It’d be cool if you could though
@@connorthesledneck1398 it definitely would be
you can't but IF you could, in some sci fi movie.. then 1 rpm would turn the last gear at 67.5 million rpm. If those gears were 6" diameter or 18" circumference, then 1.5' x 67.5 million or over 100 million ft per minute. Speed of light is roughly 59 billion ft per minute.. so 1/590th the speed of light or roughly mach 1,481.
I did some calculations. Spinning the first big gear at 100 rpm with a 1:4 gear ratio would result in the last gear making a full rotation approximately every 20 years. Wonderful project.
I think
Amazing!
I've waited this video for a loooong time
Great visual to help people comprehend how I feel about the futility of my life.
Maybe it would be cool to see a similar gear setup spin overtime driven by a windmill or the likes
I just made a comment about using a water wheel but yeah.. it would be interesting.. even on a smaller scale. Seeing something with a steady torque to use as a mechanical clock would be interesting
Hey, this is a pretty cool contraption!
*Resets the universe with the final gear*
He's back!
glad you love gears,i got lot of steel gears like from engines from tractors and hit miss engine and some brass clock gears too
Could you try and get the last gear to turn once per year exactly somehow? And you could make like a spinning calendar that could tell the day while spinning.. talk about an electric bill though!
Yea man you just need to rotate the first gear at 127.68 rotation per minute
I mean, you wouldn't need a ridiculously powerful motor
I can feel it ... this channel is gonna blow up in 2021
Ill be back here in December
How much torque do you need?
This guy: Yes
I am absolutely amazed at all the gear nerds in these comments. It’s is amazing to see people’s brain work so well
Mate, what kind of community do you usually stay in for you to be amazed at people's brains working?
But yeah, it's pretty cool to see all the smart guys here.

robert you're 12, you should do better and more productive things in your life. dad out.
@@nuggetx4086 and yes I know I am a miner because I Vape but so what
I'm high. No nothing about gear ratios. But watched it all. Thoroughly enjoyed
I just want to imagine that making a large version can make a portal
If the last gear make at least one spin, it will.
I’d love to see a full length video of all the gears spinning
For every one wondering when the gears start spinning 4:07.
When you build a gear ratio this large... you hold so much power in your hands. The amount of responsibility required to make sure you don't spin the wrong end and stop the earths rotation is astonishing.
flip it around and spin the one on the back
This would be an awesome Office desk toy
First gear be like: S P E E N
Last gear be like: spin
More like:
Last gear: s.
See y'all after 8 years when this video hits recommended again
Someone needs to make some gears out of diamond the try to spin it in reverse with a motor used in a space shuttle crawler.
Make it very big with minimal friction.
Spin the opposite gear 1/4 revolution using a lever and weight. Set it up so it takes 30 min to do the 1/4 revolution. Add fan blades at the opposite side.
Now you can cool yourself without electricity.
Who else clicked the video because they thought it made it spin fast
My mind was just blown trying to think about this.
3:35 they are made of wood so there woodn"t WOODN'T YOU GET IT FROM WOOD LMOA
sorry it late
This just gave me the idea to make a gear box that would tell you the date on the gear spokes.
I want one to put on my table and let it run 24/7 and watch it over time😂😂
Adding an arm to the end of the final gear and do a time lapse of how long it takes to lift or how much you can lift with just the wooden gears at different ratio
Really cool! Thanks for sharing 🙂
These super reductions are basically just a demonstration of how much backlash there is in the gear train. That's obviously the reason why you can cast the last gear in concrete; it's not moving AT ALL because of backlash.
Awesome video! Nice explanation as well thanks
Imagine living long enough to see the last wheel spin then saying goodbye to most of humanity
It would be interesting to see the same thing with a bunch of stacked cycloidal or harmonic drives.
really fascinating and satisfying
I got this in my recommend, I’m actually glad I did, great video
You would make a very good golf Commentator
So inn theory you can make the output move really fast? And how fast do you think you could get it to turn?
Thanks for posting... 8)
And 'Blammo' is also the 'company' in Ren and Stimpy that gives us, among other things, 'Log' (with or without the realistic facial moss, ha ha)
Hah! I still remember the jingle from the Log commercial!
This video gave me an idea. Would using the the gear ratio of a battery of mechanical energy of sorts work if you could make the most reduced gear into an elastic material, given that you minimized friction, perhaps with ball bearings, so that the elastic force could overcome it? If so, could you make a video on it, since i lack the means to make something like that myself? It is probably extremely inefficient, but it would be a cool concept.
Paint a white line horizontally across the gears...it would show the speed of turn more clearly 😊
Please try this. Glue a small mirror on the side of the slow shaft. Shine a laser on to the mirror. Project the reflected beam as far as possible and see if you can see motion in the laser beam.
Cool! UA-cam is going to blow gear reduction videos up some day.
And down the rabbit hole of gears I go.
This is *Something Uncommon* kinda content on youtube
This is insanely cool to me
I dont know anything about gears, but this is dope!
You channel will probs be big in the future!
Gears are fascinating! Would be awesome to try these on some more durable material and try to do it backwards.
if it's possible, please try to create something like that from metal and use plenty of lubricant so you can spin it from the other side and let it spin for a long time. Not sure how possible that is, but it'd definitely be amazing to watch.
Also, don't cut the assembly. That's just as frustrating as having to see all those coding youtuber skip over the coding part to show the result. Please either make a montage, a quick recap or a separate video explaining how you did it.
Im happy to see such a useful device, i will be considerably surprised if this doesnt cure cancer.
If you are not interested on learning about the thing and just want to see it spin: 4:03
This would take so long for the last gear to finish that the youtube algorithm would recommend this year's after and it still wouldn't be done
This comment will make sense when that happens
Can this be done in reverse? Like slow motor gets to super high speed with gearing?
Please show this if so.
Really enjoyed this. You’ve earned a sub :)
Yep this is about where I expected to end up at 6am
Super cool! Which laser cutter is that?
love this video, keep rocking on!
This is cool. Learned something new. Subbed!
Have you tried putting the teeth on the inside of the gear? That should make them stronger since more teeth would be doing contact at once
I'm curious what would happen if you made them out of some metal and attached a wood router to it. I know mine spins at like 25,000 rpm
and if it were made of metal and wanted to turn backwards, what would be the necessary force?
Can you see how much weight the last gear could hold (probably make it a less gear ratio so it’s easier to tell)
I see alot of videos like this, turning the energy output of a drill into the oblivion of unobservable motion, yet nothing going the other way. Would it not be more profoundly inspirational to show how gears can convert kinetic energy upwards instead? For instance, how cool would it be to see a snail on a treadmill powering a flywheel turning at 1Krpm?
