I believe you are a natural born teacher. You are able to convey complex concepts in very simple language for those of us who want to learn to make our DIY projects better and more functional.
Brilliantly demonstrated! Reminds me why I took physics in college (not engineering but just enough). Starting with W = F*D and Power algebra, with a demonstration with you kids moving bricks & a seesaw was the perfect finishing touch that made this video unique!
I love watching your channel. You are such a great person and I would love to have had a shop teacher like you. Keep up with all the good work that you do.
I am now able to UNDERSTAND the why's of certain design choices that I have previously only understood by "rule of thumb" before . This was EXCELLENT !
As an ME, there are A LOT of calculations that can be made when designing and selecting gears and we went over many of them in my machine design course in college. However, what got overlooked in the class was the basics that Jeremy goes over here. Well done sir
JF, i came to you as a lost puppy, now 2 or 3 years later, I AM THE MOSTEST MASTEREST ELEKTRUCIAN EVER!!! Okay, maybe I overstated that a but but it was because of your kind words through PM and inspirational videos that, from brain picking of my most learned ac techs and electrician friends, I suddenly have been tasked with some high profile single to 3 phase conversion solutions and being called on some CRAZY induction motor repair and implementations of VFD static conversion, efficency increases through complex capicitor math and I have learned far more than I ever thought possible! ALL HAIL THE GREAT JF! Thank you!
Sir I am 22 years old. You, stuff made here, destin sandlin, mark rober have been a great inspiration for me to learn science and engineering. Thanks for these tutorials. I do not have any degree in engineering. I have zero tools with me. But I aspire to learn how to use tools and learn to design, test and make stuff like you all, from an idea to a real thing. ❤😊
I am a retired engineer, 76. I am so excited to hear of your interest in engineering! You have more tools and information available today, than in the history of humankind. For example, when I started with micro controllers, the minimum cost of entry was about $50,000 US. That's in 1980's dollars!! You are in for a wild and fun ride :)
There's an awesome presentation from an nvidia fellow that happened at the recent gtc. It's about using agnostic data models using videos of things in motion to train a general control model for adaptive robotic movement. The mechanical side is way farther ahead than the software governing the motion for whatever task the robot may be put to use for. Like bipedal robots and a general kinematic model where the software will be aware of the most most natural movement for the dof, sensors, and such inherently without direct human intervention. Note that I do not call this ai. Llm and large data models have yet to earn the name that everyone associates with artificial intelligence. Large data models use simple mathematics backed by compute power to basically play a fast game of connect the dots for whatever task the models are built for. Agi is very, very far away. Kinda like how rasterization it's a cheaters way of making graphics look pleasant in real time. Ray tracing in games looks cool but it's a bolted on technology crippled by lack of real-time compute power and real power draw. 2 light bounces for an aggregated group of similar triangles is far from what can be done in offline rendering where it takes hours for super computers to render a single frame of woody's head (in toy story 3 for example) in a closeup with the bokeh effect around him. Ts3 was the first cg movie to use light as the governing principal for how everything looks which is why I chose it.
Thank you for explaining this and many other similar topics, you take the time to make your videos simple, engaging and informative. I've learnt so much from you and you have such a decent personality, the world needs more people like you 💪
Holy heck, as a former EE & CS major who secretly wished he knew more about mech E, this title is the intro I’ve always wanted to see. I’m crazy excited for this.
Very good video! One thing you might include around 19:30 with the downsides of the helical gear is that it also increases the amount of heat generated, which will also rob some of the power from the system. While it's a minor thing, it's still important, and you're always on top of stuff. I thought I was subscribed prior to this, but when I clicked on your video I noticed I wasn't, but I corrected that and now I am!
I forgot how awesome your channel is, Jeremy. I remember the first video I watched where you had a little rotary tool contraption in your tiny shed. You are a top 5 UA-cam engineer in my book. Up there with Mathias Wendel and TPAI. You are an inspiration to us lazy dads who probably spend too much time watching and not following along. You rock!!
I am an apprentice machinist at a machining company. While doing maintenance on a large surface grinder today, I noticed tears in a belt attached to a motor and was shocked at how forgiving the whole structure had been in that state... I admire your passion and understanding of engineering. The power of the maker.
As expected, another mechanical engineering masterpiece! Thanks for featuring our hypoid gear at 24:51 Happy to help whenever you need anything, let us know!🛠
Nice summary of the different types of gears. 50 plus years in automotive I've run into all but one gear you mention here; that is the strain wave gear. There is an e-bike I'm interested in buying that uses the strain wave system.
One of your earlier videos was on where to get free motors. There's room for a similar video on gears and gearboxes, etc. If you do that, though, could you invest a few minutes of video on things to look out for for safety and efficiency--how to spot a bad gear or when a chipped tooth is still good enough, etc.? Thanks for what you share!
To Mr Fielding, I’m a fitter and turner, also electrician. 8 years of apprenticeships, also done 6 years of university. Your videos are great. Just saying g’day and really appreciate the effort you put in to making these
I feel like I’ve been waiting my whole life for a video like this. I’ve tried researching gears and how they work, to have a better understanding. But nothing has compared to this, thanks Jeremy
Thank you for your explanations being so clear and covering the basics. I have worked with motors, engines and gears for over 40 years. You have explained things in a way that even what I already knew, I now UNDERSTAND better.
Gears and levers are like magic. I was digging fencepost holes recently and had to try and get through some very dense material. After first attempting to apply greater force to marginal improvement, I realized I should instead use leverage instead. Simply shoving the spike in and then using the length of the metal pole (8' long or so) I was able to greatly improve my effort to output (work) ratio :)
This is a superb video; huge thanks for putting it together. One thing that is worth mentioning is that virtually every manufacturer of power transmission components provides extensive resources to help designers select components. In other words, you as a designer have access to a lot of information to ensure that you’re doing the job properly.
Great introduction! I'm excited for this series :D Thank you as always for breaking things down and bringing your professional expertise to the maker community!
@Jeremy Fielding this is the second video I watch from you and I'm already a subscriber, just wanted to say thank you for making such interesting content and at the same time entertaining and enjoyable, gonna check what else you have in your videos, thanks again!
I am now able to UNDERSTAND the why's of certain design choices that I have previously only understood by "rule of thumb" before . This was EXCELLENT !
never thought gears could be so interesting, the gears in your logo make a lot more sense now that I see how integral they've been to all your projects, thanks for making this!
Love Your channel Jeremy I think it's great that you get your kids involved but , more importantly, they seem to enjoy it as well and have fun . Keep up the Great Work Sir .
So your the Gear guy of youtube ❤❤❤❤❤❤❤ also your robots are awesome can't wait till chat can use them independently and we can watch it make whatever it makes 😊 and you seem like a really good dad bro and that's the right stuff right there ❤
I’m gonna go through your collection/ library of videos, organize them into a curriculum, and study, test myself off each video until I can (hopefully) grasp everything you’ve taught. As a carpenter in Orlando for Disney and universal we incorporate much much more than wood. Thanks Jeremy! 😎
I ALWAYS enjoy your videos, Jeremy. They are supremely educational and informative, but also educational, especially when you include the 2 legged props that require food and clothing to work...
Hey Jeremy! Thank you so much! As a non-engineering background hobbyist, some of the existing resources already out there have been difficult to understand so I sincerely appreciate the simpler language you’ve used to explain gears. If you ever consider making a follow-up to this video, could I ask you to cover linear to rotational transducers and vice-versa covering the various tradeoffs you make and what you gain from using each? Things like the rack-and-pinion, scotch yoke, crankshaft and other types that aren’t necessarily gears, such as a cable spool (I also remember one that was this star shaped thing with four circular grooves to convert a slow rotation into back-and-forth linear. Basically an improvement on the idea of a scotch yoke)
I made a pendulum clock, but I cut the gears by hand on a band saw. Clock works great. Also my '65 Chevy Corvair has the 90 degree bend in the fan belt. Works fine if you have the correct tension, it needs to be kind of loose when the engine is cold. Alway enjoy the engineering stuff.
My first two clocks were cut by hand as well. Check my older UA-cam videos! I said two clocks in the video but there were actually three. And all three have videos.
You can also add a position sensor to the output of your device to sense its true position to help account for some of the effects of backlash. Different set of tradeoffs, of course, but it's another option.
Hi, Jeremy! Unless my understanding is flawed, I think that you meant to say that the diametral pitch must match for gears to mesh. If the pitch diameter is the same, you're stuck with a 1:1 gear ratio. I'm grateful for your explanation of strain wave drives in another video. Just a few years ago, these were a dark art, and almost impossible to find information on.
as a beginner i try to learn all this information piece by piece from different sources and it's confusing. thanks for the playlists. much appreciated !
This is better Jeremy... not many of has can afford or even have need for a robot or CnC Machine... More shows on the meat of mechanics is much more interesting to us wannabe engineers. I learned a lot from this one and the ones you did on motors was also interesting.
I have always loved gears! I have had so many RC cars throughout the years, go karts, mini bikes, dirt bikes, quads so I learned a lot about ratios at a young age. So I go into machines about ten years ago and bought my first south bend lathe that was missing 12 or 13 gears or something like that. I bought a Bridgeport a short time after that then found out I can make gears at home just by buying a $320 indexer from Amazon and the cutters for another 125 so I did it. I actually made a full set of gears. Wait I’m sorry, I made my first gears on my drill press lol. They came out perfect!! I have since sold that lathe and bought a 1980’s Clausing in bran new condition almost. It has absolutely no wear at all. Anyway gears are awesome and so are the machines that make them. I love it? Lmk if you ever need any spur gears made
I think I posted quick videos clips of it. I’ve done so many projects I was gonna start a UA-cam but I just never followed through. I don’t think I’d be a good talker
great job man!! I really enjoyed your video, it is the first time I have seen you cause you do stuff that is a bit out of my normal, I am a woodworker but I love making things and being able to understand the basics of pulleys/gears will help in that. again great job
This is a really useful overview, thank you. It invites many re-watches. With my optics background, I tend to overlook the mechanical side of daily technology. It's fascinating.

Yes, great job Professor Jeremy.
Brilliantly demonstrated! Reminds me why I took physics in college (not engineering but just enough). Starting with W = F*D and Power algebra, with a demonstration with you kids moving bricks & a seesaw was the perfect finishing touch that made this video unique!
I love watching your channel. You are such a great person and I would love to have had a shop teacher like you. Keep up with all the good work that you do.
I agree Mr. Fielding you are a good teacher.
I am now able to UNDERSTAND the why's of certain design choices that I have previously only understood by "rule of thumb" before . This was EXCELLENT !
Still one of the best UA-camrs out there. I am living vicariously through this gentleman.
This is one of my favorite channels ever. I wish this type of content would be promoted to kids and schools in general
As an ME, there are A LOT of calculations that can be made when designing and selecting gears and we went over many of them in my machine design course in college. However, what got overlooked in the class was the basics that Jeremy goes over here. Well done sir
This channel is one of the very best of its kind. Thanks to J. Fielding for another great, masterfully taught lesson.
JF, i came to you as a lost puppy, now 2 or 3 years later, I AM THE MOSTEST MASTEREST ELEKTRUCIAN EVER!!! Okay, maybe I overstated that a but but it was because of your kind words through PM and inspirational videos that, from brain picking of my most learned ac techs and electrician friends, I suddenly have been tasked with some high profile single to 3 phase conversion solutions and being called on some CRAZY induction motor repair and implementations of VFD static conversion, efficency increases through complex capicitor math and I have learned far more than I ever thought possible!

Congrats from the Most Bestest Wannabe Fabricatorizer Ever! Keep on DIYing!
You are an exceptional Human, the world needs more people like yourself. Was great to see you interacting with your kids 👍
I wish you were my mechanical engineering teacher. You explain designs in a way it makes total sense. Keep up the Great work. Thanks

Sir I am 22 years old. You, stuff made here, destin sandlin, mark rober have been a great inspiration for me to learn science and engineering. Thanks for these tutorials.

Agi is very, very far away. Kinda like how rasterization it's a cheaters way of making graphics look pleasant in real time. Ray tracing in games looks cool but it's a bolted on technology crippled by lack of real-time compute power and real power draw. 2 light bounces for an aggregated group of similar triangles is far from what can be done in offline rendering where it takes hours for super computers to render a single frame of woody's head (in toy story 3 for example) in a closeup with the bokeh effect around him.

@hippie-io7225 you're right. It's an incredible time to get into it. I donate learning kits and gear to people all the time.
@@hippie-io7225 Thankyou Sir for your kind words 🙂
@@jstro-hobbytech Thankyou Sir :)
Yet another incredible video. You are amazing Jeremy. Thanks!
I still can't believe you made a robot arm like that in your garage. It's honestly amazing. And inspiring.
Genius and a master at explaining complex terms and ideas in a manner that most can understand
I like his channel because he explains every thing as if he is right there with you for your understanding.
Automatic like for all of Jeremy's videos!

Nice to see you again... for some reason I wasn't getting any notifications for a long time... but here you are, looks like a great topic !
Jeremy you're a great communicator of complex issues in a format us lay people can understand. Thank you!
I feel like I’ve been waiting my whole life for a video like this. I’ve tried researching gears and how they work, to have a better understanding. But nothing has compared to this, thanks Jeremy
Another excellent video. You have a gift for explaining complicated concepts to simple people like me. Thanks for your time!
And Yes I will buy you a Coffee and donate to your Patreon page if i can Avoid buying a whole new motor!! Thanks Pal!
Thank you for your explanations being so clear and covering the basics. I have worked with motors, engines and gears for over 40 years. You have explained things in a way that even what I already knew, I now UNDERSTAND better.
Thanks for the great content as usual, Jeremy.
I Watched this video many times and I always giggled about the way you motivate your kids.
I love you man! You're compassionate and know your stuff!! Love what you do
I love gears. Im so excited to watch this video.

im getting excited about having found your channel, sir. thanks!
i feel that i had to take notes! so much value in those videos! thank you for sharing your knowledge ❤
Dang, haven’t seen your channel in a few years, glad I came across it again. You’ve been busy!
Your enthusiasm is infectious !!!
You are so very good at explaining and making it understandable. I'm glad I found your videos.
I just joined - this is *EXACTLY* the survey I've needed.
Never subscribed to a channel so fast. great content, great personality.
Jeremy I love your enthusiasm for everything you teach us! Thank you for sharing your wisdom with the world
I just want to add my 2 cents you’re an excellent teacher.
This is a superb video; huge thanks for putting it together. One thing that is worth mentioning is that virtually every manufacturer of power transmission components provides extensive resources to help designers select components. In other words, you as a designer have access to a lot of information to ensure that you’re doing the job properly.
Indeed there is often an abundance of information about components available
Thank you, you are the man. I hope your kids and friends are learning from you. Your probably the only guy in town with a real robot in his garage.
Great introduction! I'm excited for this series :D Thank you as always for breaking things down and bringing your professional expertise to the maker community!

Great information and education plus fun with your kids. That's a win win.
Thank you very much Jeremy. I love your videos. They teach us a lot. Keep sharing please. Best luck!
I am now able to UNDERSTAND the why's of certain design choices that I have previously only understood by "rule of thumb" before . This was EXCELLENT !
You had me at the Kid Work analogy! Also, another exceptional lesson! Thank you! I knew I saved those motors for something!!
What a teacher
never thought gears could be so interesting, the gears in your logo make a lot more sense now that I see how integral they've been to all your projects, thanks for making this!
Bro. I absolutely love your vids. You're a blessing to nerds and knuckle heads as well. I'm a knuckle head with nerd aspirations.
Love Your channel Jeremy
I think it's great that you get your kids involved but , more importantly, they seem to enjoy it as well and have fun .
Keep up the Great Work Sir .
So your the Gear guy of youtube ❤❤❤❤❤❤❤ also your robots are awesome can't wait till chat can use them independently and we can watch it make whatever it makes 😊 and you seem like a really good dad bro and that's the right stuff right there ❤
Great lecture on gears. Can't wait for part 2!
You da man!
Good stuff, Mr. Fielding!
Love the " nerdy" details. Thanks for all your details....
Your videos are superb! This is great overview of mechanical drive options.
Perfect timing, and great content/presentation. Subscribed!
Awesome video! Haven't seen a lot of your videos on my feed lately. Have to dive back in to all your recent stuff; I forgot how good your stuff is!
Thanks for making this video and all your video's. Knowledge and love, the two best things to share.
You never disappoint. Thank you for being so freaking awesome.
Great resource content. Thanks for sharing and putting in the effort (videos are harder than most people think!)
Fantastic video, as always! Looking forward to part 2!
I’m gonna go through your collection/ library of videos, organize them into a curriculum, and study, test myself off each video until I can (hopefully) grasp everything you’ve taught. As a carpenter in Orlando for Disney and universal we incorporate much much more than wood. Thanks Jeremy! 😎
Thanks you.
This video will mesh well with a lot of people
Dumb EE here trying to do mech things. Video is perfect timing!!!!
But wait, there's more! Forced child labor! I approve (as one who used his kids in his business.)
Great work Jeremy Thank you.
Great video. Lots of info that I thought I knew, but really didn’t. Thank you.
This channel inspired me to go back to school for mechanical engineering
So you're saying if I have a small shaft I'd be better served using more speed and less torque? Asking for a friend.
Faster rotation might help
But remember it doesn't change the amount of work being done.
Dude literally just said he has a small shaft! It's ok. Lots of Asian men also have small shafts.
lol you win 🏆 with that comment 😊
I ALWAYS enjoy your videos, Jeremy. They are supremely educational and informative, but also educational, especially when you include the 2 legged props that require food and clothing to work...
Great video, I have learn a lot, thank you from New Zealand.
Hey Jeremy! Thank you so much! As a non-engineering background hobbyist, some of the existing resources already out there have been difficult to understand so I sincerely appreciate the simpler language you’ve used to explain gears. If you ever consider making a follow-up to this video, could I ask you to cover linear to rotational transducers and vice-versa covering the various tradeoffs you make and what you gain from using each? Things like the rack-and-pinion, scotch yoke, crankshaft and other types that aren’t necessarily gears, such as a cable spool (I also remember one that was this star shaped thing with four circular grooves to convert a slow rotation into back-and-forth linear. Basically an improvement on the idea of a scotch yoke)
I made a pendulum clock, but I cut the gears by hand on a band saw. Clock works great. Also my '65 Chevy Corvair has the 90 degree bend in the fan belt. Works fine if you have the correct tension, it needs to be kind of loose when the engine is cold. Alway enjoy the engineering stuff.
My first two clocks were cut by hand as well. Check my older UA-cam videos! I said two clocks in the video but there were actually three. And all three have videos.

You can also add a position sensor to the output of your device to sense its true position to help account for some of the effects of backlash. Different set of tradeoffs, of course, but it's another option.
Great video Jeremy!
Just found you Jeremy and I sub'd right when you demo'd power output with the kids. Can't wait to start digging into the rest of your content!!
You have such an amazing channel thank you for doing what you do.
Hi, Jeremy!
Unless my understanding is flawed, I think that you meant to say that the diametral pitch must match for gears to mesh. If the pitch diameter is the same, you're stuck with a 1:1 gear ratio. I'm grateful for your explanation of strain wave drives in another video. Just a few years ago, these were a dark art, and almost impossible to find information on.
as a beginner i try to learn all this information piece by piece from different sources and it's confusing. thanks for the playlists. much appreciated !
Great video. Very informative. One could say you're a real ...gearhead.
This is better Jeremy... not many of has can afford or even have need for a robot or CnC Machine...
More shows on the meat of mechanics is much more interesting to us wannabe engineers. I learned a lot from this one and the ones you did on motors was also interesting.
Fantastic. Glad you like it. We will be on this road for a while, so I am glad to hear you like where this is going.
I have always loved gears! I have had so many RC cars throughout the years, go karts, mini bikes, dirt bikes, quads so I learned a lot about ratios at a young age. So I go into machines about ten years ago and bought my first south bend lathe that was missing 12 or 13 gears or something like that. I bought a Bridgeport a short time after that then found out I can make gears at home just by buying a $320 indexer from Amazon and the cutters for another 125 so I did it. I actually made a full set of gears. Wait I’m sorry, I made my first gears on my drill press lol. They came out perfect!! I have since sold that lathe and bought a 1980’s Clausing in bran new condition almost. It has absolutely no wear at all. Anyway gears are awesome and so are the machines that make them. I love it? Lmk if you ever need any spur gears made
I think I posted quick videos clips of it. I’ve done so many projects I was gonna start a UA-cam but I just never followed through. I don’t think I’d be a good talker
@@kennyrmurraypractice is how you become a good talker. Don't sell yourself short.
damnnn.. 26min vs 1 semester.. i go with you for life😍
Years ago I built Analoh computers. Many gears and wheels. It was a chure to have no "Back Lash" in the gears. Keep at it!!
Thank you for sharing your genius
I am deeply greatful.
Excellent information, thanks!
great job man!! I really enjoyed your video, it is the first time I have seen you cause you do stuff that is a bit out of my normal, I am a woodworker but I love making things and being able to understand the basics of pulleys/gears will help in that. again great job
