This world needs more men and fathers like yourself. Have enjoyed your videos over the years.
Indeed! Same here
Totally agree. Not sure why I keep getting unsubscribed from you, but don’t worry - I’m diligent and I re-subscribe as soon as I notice

Too true. Like "from the goodness of [his] heart". Probably the first time I've said this about anyone on youtube. A real "teacher"
Can you imagine the great engineering lessons his kids are getting? And learning in a fun way!
This gentleman is one of the most humble individuals on CZcams..so knowledgeable and articulate and great communication skills ..if he worked in a college or other institutional setting he would surely win a award.
Just thought I should drop a tip for cutting tubing. A plumbers pipe cutter, it's made to cut copper tubing but also works for brass, bronze, and aluminum without a problem.
And you can put the tube on a suitable drill shank to avoid making that lip
I use the same on small diameter stainless steel tubing. Note that a pipe cutter will still leave a burr inside that you may need to clean up.
Be careful not to deform the tube when using a pipe cutter.
Pipe cutter will leave a small collapsed area around the tube making it so the pipe won’t fit. I’d suggest cutting the brass tube with the aluminum rod inside, which will reduce collapsing and burrs and removing the aluminum rod will use the burrs.
I would cut off a piece that's too long with a hacksaw, so as to not deform the tubing, then clean it up on a belt sander to both remove the burrs and get the length correct. Setup a fence on the belt sander table that's perpendicular to the belt, and away you go. Just slide the tubing against the fence and into the belt and take off as much as you need. Of course if you have a lathe, that would be better, but I suspect he doesn't have a lathe, otherwise that would be option #1 from the beginning
In all my years of physical science classes and tooling around my work shop, I have never had gears, pulleys and see-saws compared so beautifully to torque and power. I knew all this stuff, but THANKS to this video and your explanation, I now FEEL the science and the math meshing in my brain.You turned it into intuition.
I am not an engineer, but am a high school design teacher. I've shared your videos with my students before, but THIS one is one of your greats. THANK YOU Mr. Fielding!
@wildfire405 > Years ago after nasty lumbar fusions, they stuck me teaching at UTI after years of fixing vehicles. I knew one concept requires three ways to explain it. We started with automatics & torque converters. We did the normal fan pointed at fan, then they lost it a torque multiplication. I told them say I have a 5lb steel ball on a 5 foot chain and swung it overhead and hit your hand. It would hurt? Yes. Ok, now the chain is 10 foot long swinging at the same speed! Now it hurts, but how much more? The few that had a hard time understanding how turning the fluid and redirecting it made more torque, now got it.
Just like Jeremy’s teeter-totter example. It take different explanations for some to get it!
I was taught a screw became a bolt when a nut was applied. Some screws never become bolts. Great content as always!
What if the nut is captive?
I thought a screw can create its own threads in an object while a bolt will go into already created threads (discounting fastening and unfastening into the same piece).
Alternatively, whenever I search for a fastener online, the common nomenclature will be opposite of what I think it is (I swear half the battle in finding something is just figuring out what it's called).
@@quintessenceSL Isn't that a special case - self-tapping screw? As opposed to machine screw that goes into a cut metal thread?
@@SianaGearz Most machine screws I would consider bolts (you need to cut threads for them, either by tapping or a nut).
Consider holding two pieces of wood together. The difference between screw and bolt are pretty obvious then. My point being it shouldn't matter what you are fastening. It is in how it functions.
Hence my confusion in trying to find fasteners online.
@wade reed I love that definition. I usually look at the end too, screws are pointed and bolts are flat for the exact reason you say. But I don’t think a screw should ever become a bolt, it’s designed to be driven in verses threaded into a nut 🔩
The combination of fatherhood advice and engineering is unique and beautiful, and it's just a joy watching your Videos! I hope i am gonna be a dad like u one day :)
It's always fun to watch a self taught person excitedly explaining something that they love to do. Mad props on the build.
Love what you're doing to showcase your inquisitive mind and articulate 'how' you think. It's vital to education and not everyone (aka me) can always explain it as well.
Thank you!
Dude, your life makes me smile. Thanks for the gears.
5 minutes in and I'm thinking a multi-speed bicycle would be a great visual aid for this. The arm (length from axis to pedal) remains a constant. As the gearing changes. The force required to move the arms increases or decreases, while the resulting speed increases or decreases depending on the gear ratios.
The greatest praise I can think of is that you are a good father! I plan on watching this with my daughter.
Jeremy, this is a great explanation of gears and how they work. I enjoy watching your videos with my grandkids. Keep up the great (and interesting) work!
Amazing work of art. The "that's my boy!" non-smiles are some of life's best moments. Thanks for sharing this!
Gears are beautiful!
Just wanted to say I love your videos and this has inpired me to design my own clock over summer. Thanks!
Excellent construction, video and fathering. My kids were involved with many of my projects and was such a joy. Now I have my granddaughter assisting and sometimes supervising me. 🥰😉😊
Thanks man! You are a champion. I was blown away and very encouraged at the same time that you are self taught. It give me more hope that I could do these awesome projects too.
You're a great dad. Awesome job engaging your kids in engineering! I love to see this. Great video!
I love when you mention being proud of your son! Father son bonds are so special!
Beautiful device built by a masterful instructor. Well done, sir!
Duuuude, I found your channel a week ago and it has really helped me break through the most recent threshold in my journey. Been a 5 year trip of self discovery and pursuing interest with passion. I hope to be where you are in another 5! Blessed be the man that helps himself! Best of luck, whatever you’re up to!
You are so right about them growing up so quickly. Love this clock thanks
What an awesome design, I love the planetary gear you have used, planetary gears look so cool.
👍👍👍
Its so cool to see the family working together. Thats what its all about. Youre a good man.
Oh yeah...the clock and gear explanation gets an A+.
I'm always blown away by the quality of your content. Thank you for the hard work and love you always deliver.
Awesome seeing the kids help you out.
You explain everything better than anyone else I've ever listened to. Either on line or any instructor I've ever had. Keep up the good work
You're such a good dude and very smart too, world needs more people like you.
Thank you so much, this was a wonderful video, looking forward to the next one! 😁
I remember having a clear plastic puzzle clock somewhat like yours as a kid. It had an adjustable pendulum and a main spring. I loved it.
Your "proud of your kid face" being the same as your "regular doing stuff face" is a good thing. So very right.
Thanks for addressing kerf and showing your test pattern! Important, practical consideration and verification.
Jeremy, you should be very proud, you are building a true legacy.
I love this man a stupidly high amount. i dont think i can live without his videos.
I hope your children know how lucky they are, and I love to see how proud you are of them!
Another great vid. Gorgeous clock and fun watching you (and your son) move through the planning, building and hiccups. Keep on rockin'
I always learn something from your videos. Great presentation once again.
You remind me of my late brother-in-law. He was also a great father. Thanks for the fantastic content!
As everyone in the comments are saying, that was an amazingly intuitive explanation of gears. Genuinely I can, as someone has said before me here, have it mesh easier in my head because of the subtle understanding I now have for the "simple" explanation you gave, I love these moments, a feeling of mastery.
I subscribed as soon as he started talking. I cant not have this voice in my life.
Sometimes you can chuck up your tube or rod in a drill to cut, file, shape. Sort of like a hand-held lathe. You can also use it to spin a rod against a grinder to quickly make nicely shaped handles, etc.
Thank you ! Currently working on a art project that has gears on it and this is very helpful information!
I was going to go with bearings aswell but bushings seems like it would work in my application.
Love the content and how you involve your children. "Here's what I need..." to your son instead of the "don't touch" and "you're doing it wrong!" that I grew up with
I just told my husband last week that I need to learn about gears! Thank you so much for this! I'm going to check out those links after I show this to him. Have a blessed day!
Head over to Mathias Wandel's site to check out his gear pattern calculator.
Matthias is another great CZcamsr to follow.
I'm just curious, how did you suddenly discover that you need to learn about gears?
It is a thing of beauty. Well Done!
Great work, Jeremy!! You're on the way to making your own version of the antikythera mechanism!
I miss listening to my dad talk about all manner of engineering. (He did both electrical and mechanical engineering with pulp and paper applications). I greatly appreciate your skill both with manufacturing and also educating. Thank you for sharing your talents! And kudos to your kids for keeping their internal gears working!
As an auto mechanic I deal with a lot of this on a regular basis . I really like how you are able to explain all this in a way that most people can follow . Great job!!
Dude, you're awesome. I even appciated seeing the way you interact with your family, man.
Always seriously enjoyed your work. Clocks are a big thing for me. Respect!
As always this is an OUTSTANDING Video Thank You!!!!!!
Variable pitch gears are really cool. Thanks for showing that.
Your most awesome quality is your family!! Good on You!!
It's been 25+ years since I designed a gear and you just reminded me of all those times I sat there pretending I knew what I was doing as an engineer walked by. I love the clock, by the way.
When you went from talking about levers to talking about pulleys, I began to understand how the block & tackle can increase the mechanical advantage. A pulley might be considered an infinite series of levers, the fulcrum being the center shaft. The two sides 90° from the "fully enroped" or "fully belted" end are where the work exchange happens, or opposing ends of the "lever". Thank you kindly!
Beautiful project. Thanks.
That is just an incredibly beautiful piece. Awesome.
Mr. Fielding, can't remember if I've ever commented but today I am compelled to thank you and say it is amazing how you have employed the talent God has given you and I really enjoy your videos. Especially your kind and pleasant demeanor is refreshing. God bless you and your family.
I'm an atheist so I'm not sure where his talent came from but I just like how you started out with Mr. Fielding. Upping the level of respect on the internet is always worth it. Thank you!
@@christystockman8643 Very kind of you to say so. BTW, you know no one but God can be an atheist, as only God knows everywhere God can hide. Thanks again for you very nice response.
@@fireballxl-5748hello..can you describe your 'god" to me outside of any religious book ? Is it masculine or feminine ?is it one or many..does it have a chosen people ect..I will be wating for your réponse.. thank you
Excellent video. Thank you, sir.
I love your channel can't get enough of it
Wholesome, glad I got recommended this.
Thanks for great info and videos. I took your tips on finding used broken equipment. In one week I got a treadmill, fridge, 2 industrial carpet cleaners, vacuum, dryer and mini bike all for $free$. Being an auto mechanic I ended up spotting the failures without even trying. Everything was either some kind of short in wires except the fridge had a failed evaporator fan. I plan on putting the treadmill motor onto the mini bike. This will be a fun project.
I always have to play cool when my daughter shows interest in making. I get super excited to teach her new things. She's only 7, so her attention span is somewhat limited, but for as long as she wants to learn, I'm thrilled to teach her.
Based on your videos, I can tell you are a good father and good man Jeremy. Keep up all the good work.
my son is 2. and I CAN NOT wait for him to be old enough to help me in the shop. congrats on the family time.
Just discovered your videos. Great job. I look forward to watching more of them and sharing them with my son.
Awesome as usual ! Thanks for sharing 👍
Regarding screws v bolts, there is a podcast called Engineering Commons that came to a conclusion that screws are intended to thread into a material, and bolts are intended to be attached to a material via a nut. I have always liked their determination as it is dependent upon the use case.
watching you make this really makes me appreciate how difficult it must have been for watch makers using hand tools to make working clocks. AND they're so much smaller than this... insane
Don't know how I just barely stumbled on your account, but I'm glad I finally found it. Great work!
You mags complex ideas understandable, nice work. Also the clock is cool as heck!
Really really enjoy the channel. Thank you
You're a fine teacher!
I like how he changes from engineer to surfer when ever he says tube.
also fantastic video.
Hi I am 58 and just leaned the rubies cube and scan so it every time I pick it up now.im to old to go to school and too poor to have a good tools.i just make a still press. You are a great teacher and a good human being at far as I can tell. Thanks for all our knowledge.
Very nice video! I'll take my shot at the screw bolt question:
Screw - installed to a material with or without a pre-drilled hole. Usually pointed or cutting tip
Bolt - installed in a material using either a nut or threaded shaft that matches the thread pattern
I'm very impressed, great work!!!!
Gears are awesome and all but I was way more impressed how your son listened to you without any questions at all. I bet his teachers are so happy he is in their class.
Thanks for the video Sir! I enjoy your good skills of communication as well as your creative mind. Excellent to encourage newcomers along. One thought from my experience was that a press fitted bushing will reduce the ID of the bushing. To use this to my favor, a reamer or a barrel lap could be used to remove a small amount of material once the bushing is pressed in (so it's easier to hold it while reaming).
Yes it does... but you are talking about really tight fits on both sides at that point. I only needed enough interference to hold a very light weight part in wood. If I was designing a machine from steel parts, and needed to heat the part to press it in, we have a lot more to consider. :)
Another great video. Well done, sir.
Your skills are so next level but I still learn things to apply to my novice level projects.
Thank you my brain was stuck I just didn’t fully get why you couldn’t use the mechanical advantage to get more out, because I didn’t fully understand the trade off!! Now I got it! Thanks
Very cool! I enjoyed the heck out of it, though I was screaming "Noooooooo!!!" when you were making the brass bushings😂. Loved the family involvement as well. Ciao, Marco.
I made a very similar 3D printed clock last summer. I had a lot of fun learning how to do everything.
My oldest daughter just got her first job too. When the next schedule comes out, she'll have her first day. It's one of those 'no one prepared me for this' moments.
I wish I could hang out with this guy for just one day. So cool.
Fun Sciencey Dad! The best kinda Dad! I wouldn't say the see saw was ghetto I would say you showed your kiddos how to be resourceful! You can make anything outta anything with a good imagination and some old fashioned elbow grease. Love your videos!! Keep it up!!!
What a great dad!
Love your content!
Brilliant, well done.
Hi Jeremy and family, sincere greetings from New Zealand. My understanding is that a screw (or set screw is threaded all the way up to the head: a bolt has an unthreaded shank portion. I enjoy watching your videos very much.
HAPPY FATHER’S DAY JEREMY!
Excellent work.
You inspired me into studying automation- and robot engineering!
Beautiful brother...loved it
I hope one day to meet Jeremy. I have learned so much over the years
Great Video loved it and it was fun.
Good job and Well Done Sir! This kind of engineering is what makes projects happen with people happy to do the work. Your children are taught well I believe. Maybe they were just behaving for the camera, but I doubt it. That young man writing code for you is smarter already that 9/10 of the population, including myself. You’ve done well for yourself and your Family. 👍
So let's start with thank you very much for your excellent videos. I've learned a tone. As for cutting the tube I'd say put the other pipe inside it and either cut them together (not easy) or try putting the shafts in and cutting just of edge should keep the shape of the pipe from becoming warped
Thank you for the video!
You are genius. Love your videos.
