@@ThinkingandTinkering You give me hope, keep, upping your game, I see a man . Make hydrogen and converted a car, is this possible. Love the idea. Lol, free energy. Quantum water. You can are unlimited. Thank you for helping me and sharing,
Thanks so much old mate, I love these types of gears, so many applications and uses and there is virtually nothing on the web about them, so I really appreciate you taking the time to craft some for our viewing pleasure, I hope there are more examples in the future to come. Your use of time is astounding, I am always amazed at what you achieve in such a short period.
In my local brewery, they have a steam engine that can run the whole process. Each pair of cogs is made of one cast iron gear and one wooden peg gear. if anything goes wrong, the pegs shear and save the cast iron from any damage :)
You don’t ever just learn one new thing with Robert, you casually add so much in every video. You very simply and with great charm give wonderful detail and make learning so easy.
Thank you for sharing! I'm an old Caterpillar mechanic. I had never heard of a peg gear but, I'm just getting started making whirlygigs so what you showed me is priceless! Your idea to make an oscillator by simply removing half the pegs is so simple yet AMAZING! 😁
Totally love the good wooden old peg gear tech!. Reminds of all those wonderful atmospheric windmills and ancient machinery i loved visiting on weekends out in my childhood. Then when i got back home i would enthusiastically draw out lots of plans for inventions, and try to make them in the humble garage workshop. Was very much inspiring satisfying stuff, and learnt alot. Well even if some things didnt go exactly to plan :D
Very nice. And the quick discussion of appropriate use of technology is gold, in my opinion. Having experience in traditional woodworking, flint knapping, and blacksmithing, I've come up with solutions to challenges on the job site that just were not in other folks mental tool boxes. Thanks again for freely sharing these great ideas.
Just stumbled upon your channel and all I can say is you're one heck of a good communicator. If all teachers were as knowledgeable and clear in their prose as you are, we would have generations of enthusiastic learners.
Thanks! Very nice presentation of the possibilities with peg wheels. Love your attitide and energy! And I think you are so right when it comes to the importence of being able to create things with more simple tools. Would be wonderful to see a video where you present Christoffer Polhems mechanical alphabet. There are so many possibilities. 👍😊
Robert I have for all my life loved inventing things and just making things I got curious about and I am sure just watching what you do really inspires me to make something. I found your channel because I searched for Gears for a machine I am making and I only though of a classic modern gear but seeing you make the Cage gear and how easy the use of them is really helped me on the way. I wish that there was a place just for people to try to invent and make stuff together that really could be awesome sadly the culture today is buying something that is already made.
I am trying to figure out an easy way to make the 4 stage herons fountain you showed into a 'perpetual' water feature in my garden without running electricity to it. But i couldn't figure out a way to make it turn itself over without a 'mains electric' motor attached to it. This has given me some new ideas. Thanks Rob, I really do adore this channel and what you put out into the world.
Next on RMS, The Power of Flight, recreating Da-Vinci's human powered flying machine.....from string and a few bits of twig.... lol You are amazing. I wish I had a role model like you growing up.
Excellent and valuable message about the importance of learning the roots of various processes! Experiencing the manual processes growing up, made me a much better craftsman in adulthood. I also highly recommend trying some projects using non-powered hand tools exclusively. (very old school style ;) Though they do, sometimes, take longer, using the vintage tech tools can be a very meditative , centering, and exceptionally satisfying experience! The "Zen" of hand tool use if you will! Thanks for another great video Rob!
geoff graham Thank you for reuniting us with the precious past when we had no 3D printing machines and frozen chooks. All we had was our manuel labour, some imagination and some basic hand tools. 1 second ago
I liked the commentary on 3d printing and the making by hand. I got a tiny 3d printer n a standard one and I noticed that as well takes so long to produce and dont appreciate it near as much. I barely use either now. Just for replacement parts handles organizing constructs, wood working jigs tho I have alot I've printed like pocket hole jig router jigs. That's about all I use them for that and toys for the kids lol Second thought you could use wood circles and use bolts ,washers, nuts for the pegs of your worried about longer term ware and tare. Even a threaded rivet . Or a circle of HDPE plastic from a 5 gallon bucket.
They are a tool that is good for a job mate - what gets me is when folks tout them as the answer to everything - nice suggestions too - good post mate - cheers
Agreed. I use all styles of gears and chains drivers. I'm working on some wooden roller chain using some cheap 1/4 in osb board scraps I have, but then again you can buy popsicle sticks cheap in bulk and 2 different sized dowels very cheap as well. Roller chain "bicycle chain" mesh well with peg gears to transfer motion long distances if you design the chain and gear correctly that is. Makes a great sound too. I'm self teaching myself everything so when I find out there is another way even if its obsolete I like to try it. When comes to kinetic energy transfer. I jumped in the middle of everything I'd preferred to start with primitive base of concept style stuff but I got a bit to excited. Thanks for the video was a pleasurem
Who in the heck give a thumbs down to these videos? Must be an elementary school drop out, watching on their old Obama phone, eating Cheetos they bought with their SNAP card. Robert Murray-Smith you are absolutely right about perishable hand skills and the corresponding brain. Keep these videos coming
Totally agree about the importance of keeping touch with basic skills and tools: it is so important for the process of thinking about whatever we make.
You can also clamp your jigsaw upside down in a vice and use a cable tie to hold the trigger on and rotate your square piece of wood using the centre hole on a nail. This same method works with metal disc's and bolts through the holes tightened with nuts for a longer wearing peg gear. Even nails through a wooden disc makes a very quick peg gear if you have finer requirements. Love the video as always, not sure why I didn't get the notification. Blame UA-cam not RobTube, lol 😇
You can do the same process with a chopsaw, or use a standard table saw. In both cases, all you need to do is keep the blades running at a set depth, then after you spin your material around a couple times just set the cutting depth a little deeper. Repeat until you cut out your perfect circle! Cheers
Fantastic , so true what you say about keeping this stuff alive, The ship yard here have actual tools that people don’t know how to use , the men that new how are long gone...
Found the tutorial for making cage/peg gears I was looking for...and then the reciprocating motion! Wow, let's try that instead of a slider crank! There's no variation in speed during the cycle?
Awesome and cool, to quote, and you are right Robert about making things by hand, I think there is nothing more rewarding then hands on. I have limited space and the only basic tools plus a scroll saw. Great video, thanks Robert.
I like these bc is alot easier to run several different gear sets off the same drive wheel just depends on how thick or wide you make them and how wide you make your gears can use popsicle sticks for the outer edge style pegs they mesh better in my opinion. A quick paint and seal can use as a rough water wheel
Lovely words of great importance in this humble video of yours. I can relate to this from the perspective of the high tech world of lithography. New engineers do not come with the knowledge of how stuff is made at the high end level and many do not have the very important perspective of making things by hand. Simple things become humongously important. Case in point, the story of the laser grating. As the actual real story... history..goes, a guy spent 10 years of his life making grooves on a piece of metal. Grooves so tight and precise that they refract light into it's components. All by hand on a simple groove making hand tool/machine. So precious are these metal pieces now because most gratings for lasers come from them as plastic copies. Who will do this again if we were to loose the existing machines? 10 years. No other machine can make them. I will find the link. But yeah, it brings it home, you need glass blowing, grating groove making, and many other innocent looking activities to make microchips.
Love it Robert. Also agree with your philosophy about basic skills. Using high tech tools, after a while you loose touch with skills that are much simpler, and force a higher degree of creativity.
Hi Robert , love your videos ,I'm always fascinated with your knowledge and your unique way of making things sound so simple to construct , maybe you could make a video on a simple way to find the true centre of a circle , something I have always struggled with because of my inability to grasp simple mathematics .🤗😍
you can but depending on the speed of change and the the weight you will probably introduce "gear slip" with a physical interface of wood you only have to worry about the weight exceeding the strength of the dowels and the wear over time.
With gears in general you're introducing the physical strength of whatever you're using (wood, metal etc.) and torque (with proper power behind it) which could not be replicated with magnets in any everyday sense? I guess it really depends on what you're doing. The strength of material needed, and the power required behind it to drive it?
Very high speed reciprocating mechanism is very noisy and not reliable for linear generator. But if and only if a mechanism could be devised using magnets, then, I guess it might open up some doors to a reliable linear generator.
Excellent info! I've always imagined something like this being used to build the pyramids of Giza, using the Nile river for input power. The reciprocating gears would work perfectly to lift massive stone blocks level by level if you daisy chain a bunch of them together by adding more pegs on the circumference of the input gear, 90 degrees offset from the pegs that drive the cage gear. Using massive timbers to build the gears, they could produce some phenomenal torque by utilizing gear ratios. Large stones could also be cut with this type of mechanism by attaching a lateral cutting saw blade. This makes perfect sense in my mind. What do you guys think?
Its funny you talk about 3D printing. I have a side project that I am working on for a streamer. Kinda like the batman signal. It doesn't spin in a circle but goes back and forth. This project just helped out a ton. Question though... for this particular project (the mini one) did your 30* just happen to work out with the dowel size and the circumference or was there a lot more planning behind the scene? Just asking because it moved smooth!
A couple of interesting points! Every maker (and non-maker too) should visit a watermill or windmill to see exactly how these gears can transfer quite large loads. Also to see the different types of wooden gear! The other point comes down to how you learn about stuff. If you learn by rote you will be able to repeat what you know. If you learn How the stuff works you are free to expand your borders and evolve new techniques! Long may it continue!
Oh WOW, you gave me an outstanding overunity idea. Put 9 peg gears on the apparatus you have sitting on the table. Turn only one of them with a motor but have all the others running generators. That is a giant overunity of electricity.
Nice build Rob, simple gearing with basic maths and DIY tools, with all the mysticism taken out (well, most of it anyway!) I like that a lot, I used to do a fair bit of gear cutting on horizontal Mills and hobbers, with a Zeus book in one hand and a calculator in the other, it's amazing how it can be condensed down into simple ideas and rules of thumb, it might not be the most efficient and a bit noisy, but hey it works I love the projects where you take something that seems complex and brain stonkingly hard to do and break it down into easy steps, I'm not that good at chemistry and I've probably learnt more about battery chemistry from your channel that has actually sunk in, than any other channel on the subject, I was trying to think of a name for this one... Rotary wiggler? If you like weird mechanical contrivances, search for 'animated mechanism' and you will have a ton of mad ideas
nice one mate - I will do exactly that and I agree the point here is to get something built that works not spend days scratching your head over the math lol
I've just watched a Jack Hargreaves (Out of Town Presenter) explain the facts about Hornbeam wood How because of its properties it was a favourite wood for mill gears
Thanks for sharing this is interesting and knowledge video, one of my request sir , you please try to make a any free electricity generated project, I think it's possible to -peg gears, used of gravity force , pandulam escapement and etc . What's your opinion please reply Sir
Rob, loving these inspiring video of late. If ever you have a chance, I’d really like to see you think about and put together a DIY Perovskite solar cell! I’ve been very curious about these and have seen a few DIY video about them, but knowing you, you find way to add a graphene twist to them. Lol btw, taking appart my first microwave today to start my vibration generator experiment! Cheers mate!
A valid point made about 3d printing. You need to know how to go around the corner properly before you can cut it. Something I try to instil in my students.
Put the lever action sideways and it could be a great way to capture power from waves or tides. More from waves I would think but, I suppose with the proper gearing, It could be done with tides as well. Great video either way, maybe try it using magnets instead of pegs? Cheers Rob.
That was something cool I have not seen before. Ps I understand where you are coming from on 3d printers, but you get bigger ones with bigger nozzles but still takes a while to print.
I once heard of a washing machine some bushman had made for his hut out way in the bush. It was powered by water and was entirely made from wood. I bet there was a peg gear in that, powered by a water wheel probably.
I've been watching a lot of videos on mechanical calculators recently. Wonder how hard it would be to build one of those that used a bunch of those cage gears? I'm really interested in ways of doing things with simple tools, because my shop is... sparse. It's demoralizing to fire up a video on some cool looking project and then look at what's likely tens of thousands of dollars of fancy equipment they have in their shop. I'm much more a fan of the Paul Sellers approach.
We, as a society, absolutely have lost touch with hand fabrication techniques. I was a fabricator for the past 25 years and have noticed the decline of people with this mindset. Shops around here have started running really wonky, if you will, and don't allow any time for the difficult stuff. I threw my hands up and have gone down a different path, but I still love to create!
Now you remind me of an angled water wheel. I mean it’s not vertical nor horizontal, it guides water down via a slope. Somewhere I have a small booklet with drawings and explanations.
no they wouldn't and they wouldn't even know how to repair the grid this. kind of stuff leads to the basic understanding needed to creat, run and repair all the high tech stuff we rely on - or at least that's what I believe
2:40 and here's one I'm preparing earlier Took me a while to really see the advanages of CAD design and 3D printing, especially for prototyping. I still struggle with email tho, so I'll stick with luddite analog design and production. 😁
In respect to using a chop/miter saw for cutting a circle: this can be dangerous, but with care once most cuts are made you can rotate the board clockwise, when work piece is on the right of the blade. Quite accurate this way just be careful everyone😉
Great stuff, Rob. It seems like you can do almost anything with cage and pin gears. Except maybe a worm gear (or equivalent). Unless, of course, you know different - (challenge). I can't figure out how to do it. 9
@@ThinkingandTinkering Great. I think I've worked out how to do it. But without workshop facilities it's going to be a bit hard to build it. Still. I'm going to have a go. I'll be interested to see how you get on with it.
Robert Murray-Smith, do the pegs need to be particularly strong? The force is being applied to the short end of the lever, even if the lever is longer. Furthermore, it’s the same as the leverage being applied to the pegs on the input wheel. I was actually thinking that swapping the two cages for wheels may make the thing last longer, because the input wheel is currently doing a lot more work than it otherwise might. 💜🤓👍
Respect, love and gratitude. You are unlimited. Loving the good energy. Thank you for helping me. Respect

The simplicity of the reciprocation mechanism put a giant smile on my face.
cheers mate
With a weighted flywheel it would also work in reverse, taking reciprocating action from the bellows to rotations action on the flywheel.

nice one mate - I will do exactly that and I agree the point here is to get something built that works not spend days scratching your head over the math lol
Thanks, I want make for an automata idea I have, the arms would be the cams to push up the units
I've just watched a Jack Hargreaves (Out of Town Presenter) explain the facts about Hornbeam wood How because of its properties it was a favourite wood for mill gears
Amazing inspiring videos Two thumbs up for you, Sir 👍👍
I need this for a project. thanks robert!!
this is awesome. got advice on making a flywheel by hand?
Thanks for sharing this is interesting and knowledge video, one of my request sir , you please try to make a any free electricity generated project, I think it's possible to -peg gears, used of gravity force , pandulam escapement and etc .
What's your opinion please reply Sir
Rob, loving these inspiring video of late. If ever you have a chance, I’d really like to see you think about and put together a DIY Perovskite solar cell! I’ve been very curious about these and have seen a few DIY video about them, but knowing you, you find way to add a graphene twist to them. Lol btw, taking appart my first microwave today to start my vibration generator experiment! Cheers mate!
A valid point made about 3d printing. You need to know how to go around the corner properly before you can cut it. Something I try to instil in my students.
Put the lever action sideways and it could be a great way to capture power from waves or tides. More from waves I would think but, I suppose with the proper gearing, It could be done with tides as well. Great video either way, maybe try it using magnets instead of pegs? Cheers Rob.
spot on mate and you are right peg gears are the basis of magnetic gears
That was something cool I have not seen before. Ps I understand where you are coming from on 3d printers, but you get bigger ones with bigger nozzles but still takes a while to print.
I once heard of a washing machine some bushman had made for his hut out way in the bush. It was powered by water and was entirely made from wood. I bet there was a peg gear in that, powered by a water wheel probably.
highly likely mate
I've been watching a lot of videos on mechanical calculators recently. Wonder how hard it would be to build one of those that used a bunch of those cage gears? I'm really interested in ways of doing things with simple tools, because my shop is... sparse. It's demoralizing to fire up a video on some cool looking project and then look at what's likely tens of thousands of dollars of fancy equipment they have in their shop. I'm much more a fan of the Paul Sellers approach.
First thing I thought of is a scroll saw. Super cool.
We, as a society, absolutely have lost touch with hand fabrication techniques. I was a fabricator for the past 25 years and have noticed the decline of people with this mindset. Shops around here have started running really wonky, if you will, and don't allow any time for the difficult stuff. I threw my hands up and have gone down a different path, but I still love to create!
How do you think someone would go use them to make a pedal powered wagon ?
the same way you would use them to make a water wheel - just smaller
I love your videos and I love your philosophy.
Can out reverse it? Put a reciprocating motion in and generate a continuous rotational motion?
I suspect you could but you would need a ratchet and pawl I would think
Now you remind me of an angled water wheel. I mean it’s not vertical nor horizontal, it guides water down via a slope. Somewhere I have a small booklet with drawings and explanations.
I wouldn't mind a look at that myself
Wow. Very ingenious.
Excellent video!!
RMS, if we lose the grid, most people will not have the basic understanding to make even these simple devices!
no they wouldn't and they wouldn't even know how to repair the grid this. kind of stuff leads to the basic understanding needed to creat, run and repair all the high tech stuff we rely on - or at least that's what I believe
Amaing. That would be great for a wind driven well water pump
we really need to get you rescued from that deserted island!
lol
Lovely vid, many thanks.
2:40 and here's one I'm preparing earlier
Took me a while to really see the advanages of CAD design and 3D printing, especially for prototyping. I still struggle with email tho, so I'll stick with luddite analog design and production. 😁
@Craig MacDonald Kinda like calculators tho... much easier than a slide rule 🤣
I see the advantages mate - but it's like any tool - good for a specific job - what gets me is when it is touted as the answer to everything
Yep, the first metal lathe would have been made using a wooden one😲 CNC is amazing but nothing beats the satisfaction of hand made.
How to make an auto hammer! Thanks
Great insights as well.
In respect to using a chop/miter saw for cutting a circle: this can be dangerous, but with care once most cuts are made you can rotate the board clockwise, when work piece is on the right of the blade. Quite accurate this way just be careful everyone😉
nice tip mate - cheers
You could put a motor on it and attach the arm to your ammunition press with the proper strength and make bullets while you sleep.
Modern day Leonardo!
or Christoffer Polhem :-)
lol - cheers mate - didn't Leonardo use this mechanism in is ornithopter design?
Excellent Mate!
cheers mate
Great stuff, Rob. It seems like you can do almost anything with cage and pin gears. Except maybe a worm gear (or equivalent).
Unless, of course, you know different - (challenge). I can't figure out how to do it.

lol - ok mate that is a gauntlet thrown down if ever I have seen one lol
@@ThinkingandTinkering Great. I think I've worked out how to do it. But without workshop facilities it's going to be a bit hard to build it. Still. I'm going to have a go. I'll be interested to see how you get on with it.
@@kenrowe167 awesome mate - I was just pondering it
Remind Luke about this so he can make a hand crank well.
Phenomenol ! That system could be used to power a hacksaw 🤔
Is the second cage gear actually necessary? Couldn’t you get by with a single cage that’s double wide? 🤓🤔🤷♂️
yep but that would make the pegs weaker - you don't need cages at all you could just make 3 peg gears
Robert Murray-Smith, do the pegs need to be particularly strong? The force is being applied to the short end of the lever, even if the lever is longer. Furthermore, it’s the same as the leverage being applied to the pegs on the input wheel. I was actually thinking that swapping the two cages for wheels may make the thing last longer, because the input wheel is currently doing a lot more work than it otherwise might. 💜🤓👍
Fantastic!
기계 원리가 대단하십니다
[Norm Abram voice] There is no more important safety rule than to wear safety glasses!
how about don't cut your fingers off? lol
Tnx.
no worries mate
okay who read my mind, was gonna say do some leonardo gears.... Awesome.
lol - for sure
Brill Rob! 👍
cheers mate
yes but a rotary table would make them far more accurate and efficiently with out having to add a CNC mill or something,
yes it would mate and that is a nice tip - cheers
