Aerospace engineer here: Every time I watch your channel I feel a little smarter for having watched.
Your doing things and explaining them at a level we don't get to see often in engineering. By some accounts people might say "Can't CNC do this?" and the answer is YES. That's NOT the point because all CNC is still based on certain fundamental principles and techniques.
You're showing us some of those fundamentals.
Thanks.
this is so cool! do you sell these to put on pencils?
@@Echo3_ I'm picturing a version of this mounted on a ring...
@@Tasarran id play with it until it broke lol, this thing is really cool
Please make a flying tourbillon large scale 😊😊😊😊
A model that only includes the Sun, Earth and Moon is a Tellurium/tellurion. One that only has the Earth and Moon is a Lunarium. An orrery optionally includes other planets as well
Today I learned: ^^^
Came to the comments to check if anyone else had mentioned!
What wonderfully delicious words!
That's so cool to learn
Very cool!
Can I say just how soothing these videos are. The birds chirping, the mellow voice, the beautiful brass chips. It's heaven.
Go ahead
No.
For people like us, yes this is an absolute pleasure to watch.
Classic ASMR.
Control of audio to prevent harsh noises is key. With machine tools, clearly this guy gets it.
In contrast to the place where the metals were mined. No bird sounds. Hard work. It’s hell. Enjoy the video.
Next time you cast something small in silicone, remember degassing is only strictly necessary if you are curing at ambient atmospheric pressure. Because your mold was so small, you could have easily put in in a pressure chamber, and put it under pressure. 20-30 psi is great for small silicone parts. Any bubbles are compressed and don't return after the full curing time of the silicon is achieved.
Beautiful work. Subbed.
This is correct for casting hard resins, but because silicone is stretchy, the gas bubbles blow up like a balloon when the positive pressure is removed from the outside but remains inside the bubble. The firmer the rubber, the less this is an issue. Even a vacuum cleaner will provide enough suction to get most of the bubbles out. Just make sure you have a bleed valve that can handle the high flow (or be read to turn off the vac or disconnect the hose), otherwise you'll just have the uncured resin spread all over the chamber.
If you want to use the positive pressure method and are looking for a single use mould and a matte surface is desired, as was the case here, just make the mould from plaster. Then you can just dissolve the mould in water off the outside of your finished epoxy part.
@@IOUaUsername Drywall or joint compound can be used in a similar way to plaster. It conforms with very fine detail and melts in water, but might be easier to find and in smaller amounts. Or you can mix it with wood glue for a rock hard product, sandable with fine detail. It makes a good surface on foam.
@@IOUaUsernamehow would you make a mould from plaster for this? A sphere isnt tapered in the same direction on all sides, so you either need a flexible mould or a 2 part hard mould. Plaster is pretty brittle so youd have to use quite a bit to make the walls thick enough + provide space for the registration marks, plus it requires 2 curing sessions which is more annoying than just one in silicone. Ive also never seen anyone using a pressure pot on silicone have the bubbles appear once back at normal pressure, is that something you've had happen or just an assumption?
@@QuentinWeslost wax method maybe.😊
@@IOUaUsername I use a pressure pot for my silicone molds and get no "regassing" at all. all the resin pours are smooth. The pressure doesn't shrink bubbles, at 35psi the gas redissolves into the mix, it doesn't return once the silicone is cured. You HAVE to leave them at pressure during curing is the downside to this method. Depending on the size of the project, it can be prohibitive.
i am shocked that you went the extra mile for the small Steel bridge to be rounded over and almost polished, giving tribute to ultra high watchmaking...
Weather or not you intended it, i feel extremely honored as a watchmaker
You're a watchmaker? That is amazing. I have always wanted to try it. Had things gone differently, I would have jumped into this when I retired. I would really like to see your work if possible.
I noticed that, all that was missing were interior angles, anglage and black polishing. Looks just like a tourbillon or full balance bridge. I'm a collector, not a watchmaker but I just found this channel and clearly he has some experience in the field. If not he should call Arnold & Son, UN or Jacob & Co. immediately.
My crafting involves making molds and let me tell you, a custom machined sleeve for a ball bearing mold is WAY over engineered and I am HERE for it....
For an 8mm Sun, to scale, the Earth would be about 80 microns, the Moon would be 20 microns, the distance between Earth and the Moon would be ~2.5mm, and between the Sun and Earth would be ~93cm.
This sort of model is never made to scale, aside from the orbit timing. In the modern era they are used as teaching tools in regards to the relative speeds of the orbits of planetary bodies around the sun. We use other models for teaching about distance, both as a practical matter and as a developmentally appropriate practice (for elementary age students).
It would be cool to have a true-scale true-orbit Orrery though. It'd be a very intricate project.
Absolutely. We thought about a scale model briefly but it's tricky in practice. Fun to think about though.
@@kmoecub Not sure he was suggesting that it was incorrect because it wasn't to-scale; Just giving some relevant figures.
If they are to scale you'll either don't have room for or theyre too small to make.
Making such a contraption AND filming makes this almost unbelievable. One of my favourite channels.
I've watched watch restoration for a while but as an ex mechanic this is much more my cup of tea. Incredibly intricate engineering always have time to watch a master craftsman at work wish I'd have given my life to something like this to consume me.
As a Magic: The Gathering fan, and a niche manufacturing RUclips connoisseur, thank you for informing me that an "Orrery" is indeed a real thing. I literally had 0 idea.
Dude, I mill stuff that ranges from twelve to seventy-five inch OD, so this stuff here looks like outright sorcery. *And* you manage to get a beautiful finish on those cuts!
I really appreciate the effort that goes into these videos, not many people will notice many of the details and few will notice how good the audio is but good audio is crucial to make a good video, I particularly enjoyed hearing birdsong in the background, that's a nice touch !
Looks like a lot of people noticed. Like a massage for the brain.
Miniaturized machining is so pleasing to watch
If there is such a thing as visual ASMR, this is clearly an example of it.
Do I do any machining? No.
Do I plan to do any machining in the future? No. (though maybe CNC)
Do I plan to make a mechanical solar system? No.
Do I love watching your videos despite all those things? YES!
A full solar system reaching out to pluto in this scale would be an amazing project
This is a fabulous example of how much care and effort goes into making even the tiniest little thing. You did a fantastic job making something so small and beautiful.
8:25 ridiculous. Absolutely ridiculous. Incredible work mate.
100K subs is a crime for this amazing quality of work, hope you explode after this vid.
Up!!!
Beautiful work on a rare tool build. We shared this video on our homemade tool forum last week 😎
Your patience alone is remarkable.
Nothing to do with patience,it’s the desire to make it !
This was amazing, I dream of having skills and tools like these one day
Orreries are my absolute favorite mechanical creations. Loved this video, the birds are nice to hear. 🥰
Me too the only ones I could afford are from eaglemoss I have 2 both on my channel
the quality of these videos are meticulously delicious😍
Fantastic work! I rarely watch RUclips videos right through, but this held my attention from start to finish.
Yea definitely keep expanding on this project, I love it! Can’t wait to see what you do next!
No matter how many of your videos I watch, I'm continuously astounded by the precision and skill that go into these projects. Holy crap.
On seeing the final assembly, I wondered, would it be possible to achieve an even smaller one by supporting the bridge on the arbors of the sun and earth gears themselves? There seems to be just enough room there to sneak it in.
I’ve always wanted an extremely detailed orrery of my own… moons and all, but your level of detail is Outstanding!
Thought this would make a great ring when I saw the thumbnail!
Nice work on the collet handover idea.
Mesmerising from beginning to end 👌
Congratulations on passing the 100k mark! Love your videos and no matter how many I watch I’m still taken by surprise when something of recognisable scale comes into view.
What a beautiful piece! I have had a fascination with orreries since I was a small child in the 80s, when I saw an orrery in the Jim Henson movie, "The Dark Crystal". I'm also a miniature enthusiast, so this piece covers so many of the things I love! One of the first things I thought was that a piece like this would make an incredible ring, or even a pendant. One can dream!
this is super cool! also thank you SO MUCH for having actual subtitles from day 1, it's a huge deal.
Hello,
Thank you for your work, it's amazing ! As a mechanical student, I love it !
For the miniaturization of an helliocentric model, I think about the the Van Cleef & Arpels Midnight Planetarium. A watch showing the sun and every planets turning around it. It's a really nice piece. And as you mentionned Antikythera, there is Hublot, who made "Anticythère", a wearable watch powering the Anticythère mechanism. A beautiful watch piece.
But otherwise, I don't know a model as small and elegant as yours with the moon, earth and sun. It's "cute" ^^ and I like it.
I'd LOVE to see a more complex version of this! Beautiful already, but I sense so much more potential!
What an incredible piece of engineering.
Beautiful work. I'm inspired to make a scaled up version on my 6" Atlas. I have a wall clock to finish first though.
The miniature painter side of me really wanted you to paint the sun to get the desired finish instead of just tint the resin. Getting that to look right is an entirely different skillet that takes as much time to learn as machining does though.
10:00 even though I skipped the ad, I appreciate that you had someone else record the VO for it.
Your channel is one of my fev. Channel due to fine details and soft voice.. I loved this video so much.. Thanks for the beautiful video.. ❤❤❤❤❤
Would love to see an entire solar system. Nice work!
I love your videos! As a machinist who makes parts for heavy industry, I find this to be incredibly soothing.
Beautiful machine work. Awesome project 👍
What a lovely little creation! I enjoyed watching the process and learning about it, and seeing the finished project was so beautiful!
Why is your voice so calming? For some reason I cannot explain it just makes me calm instantly
These videos are simply fascinating
The complexity of such small parts to be made so precisely it's unthinkable until you try it
A couple of weeks ago I had to make a small 2mm long cilindrical locking pin for the crown inside an angle grinder gearbox and it was quite a job.. indeed I don't have a proper shop to do that but managed to fix it and I'm so proud of it every time I use the tool
Congrats on the almost 110k subscribers 😅
This should be in a wristwatch. Please make it happen the next time you revisit this project!
Wonderful in every way.
Also, that is one mighty toothbrush!
This is exquisite. Subscribed!
I am amazed by these watchmaker tools, like the lathe and milling adapter. I had no idea, how to even fix such small parts within my ER25 collet to turn or mill these parts. Not to mention the dividing table to make ultra-small gears.
Beautiful work.
I agree
So beautiful! I would love to see all planets in the same scale 🫢
This is so beautiful ❤
If you do make it more complex id love to see
1. the earth turn 365 times every year around the sun
2. The tilt of the earth, in ratio with the sun, creating summer, winter
3. Use a hot bulb for the sun and glow in the dark pigment for the earth, to really see the summer and winter , day and night
All the best 🌍
this is stunning, thank you
Bravo. Nicely done. Camera work, narration, machining, and concept. Excellent. Thanks for taking the time and sharing.
That is utterly incredible. And a joy to watch!
Outstanding and entertaining ... as always. A concentration of everything I love about micromachining. Schaublin 70 lathes are really superb pieces of small tabletop machine tools, very complementary to Lorsch-type watchmaker lathes. Waiting the next video.
I am truly blown away by your amazing skill. Just attempting such a project is a serious undertaking regardless of the results. But you create a functional work of art. Much respect to you my friend 🙏 🫡. Thank you for sharing your incredible project with us all. Also I absolutely love your lathe. I would very much enjoy a deep dive into its workings if possible.
Just incredible! A joy to watch:)
So well made video I found myself just completely sucked in slack-jawed and all. Subscribed!
lovely. Can you explain the staking tool in a future video?
Ahhh…the Joy you bring, the loneliness you banish….thank you❤
Awesome video! Very inspiring. I like to think I am moving towards this level of precision, but have a long way to go. I am building two different planetarium projectors. The first is a relatively simple three axis starball. I am working on a more complex one with planets akin to the GOTO design approach. Basically it's a projection orrery. For this I am setting up a small machine shop, but this is a large machine with very loose tolerances by comparison to what you are doing. I am always impressed and deeply inspired by watchmaker's level of work. Well done!!!
I've always been interested in watchmaking, and this video was such a pleasure to watch. The skills, applied with such calm, are aestonishingly beatuful. Keep up this amazing work, I'm definitely looking forwards to the next projects.
This was such an awesome video! I hope you never stop uploading :)
11:56 I appreciate that you machined a bucket for the little ball, but you could have just used like a pop cap, or a Peptobismol measuring cup lol
Duuuuuuude that is AMAZING!! Holy moly I am impressed!!
Absolutely amazing work!
I can’t explain it but I really enjoy these videos.
Neat. I'd love to see you have a go at doing one of those super complex watches. You know the type that practically dances on your wrist.
Always a pleasure
Thanks for sharing
Work of art. Outstanding.
I own a Sun/Moon Orrery from the 1800’s that was featured on an episode of American Pickers, hand-picked by Mike Wolfe and Frank Fritz from an Oddfellows Temple in Akron, Ohio and it’s nowhere as cool as your miniature!
Its criminal that this channel doesnt get way more views
Nice one! Would be cool to embed a LED into the "Sun", so it shines, then can also show eclipses on this thing 😄
What a skill to have, I’m suitably jealous 😊 thank you for sharing 😊❤
I had tears, remembering how as a kid I wanted to learn how to make tiny things of detail.
You have blown me away! I love this sooo much! Wow this stuff is amazing! I am seriously floored by your work! Sublime, superb and fantastic to say the least. Thanks you!
This is mind boggling and amazing!
Absolutely stunning mate👏👏
I am loving your work!
A new Chronova Engineering video, what is it my birthday
My curiosity has been answered for a long time with this video, I am a lathe worker, I have been in this field for 35 years but I really want to know about the micro gear process.
It's especially marvellous that this is on the end of a pencil. I think I would be tempted to put some sort of luminous dye in the sun, but perhaps that's a bit tacky :)
Wonderful video and a lovely project
Absolutely mesmerizing as always, watching your videos! Thank you!
Thank you for the production. There’s are very enlightening
As always, amazing!
Makes me want to make a large one for my garden.
Probably have to do inverse of the square on size to distance ratios to make it work…
This would be super cool mounted on a ring!
I haven't seen such small chip branches before 7:00. So smol
Would love to see something like this with a sunstone sun and azurite/malachite Earth. TheMoon could possibly be a small jet bead. Excellent video
Wonderful, as always! However, this is a Tellurium (sun-earth-moon model), not an Orrery (which is the whole solar system with the 8 planets and sometimes the dwarf-planet Pluto).
Exquisite! Thank you.
Wow...Favor de ir al oculista 2 veces al año para que puedas continuar con ese tipo de trabajo.
Beautiful work!
wrist mounting it with a glass dome over it would look incredibly sick
Very pretty. Good camera, especially down the microscope.
Out of this world!
That is superb! 12/10
Tu travailles très bien; c'est admirable de te voir à l'oeuvre. Amazing!
Absolutely fantastic!!
