If Wallace and Gromit were into machining, this would be their first project!. Lovely project, masterfull cinematography, good narration👌

Looks nice, Im a clock repairman and whenever bells are mounted they are fitted with felt washers on the top and bottom where they mount. This prevents the dampening of the sound

I hope he sees one of these comments, and goes back and adds the felt, even if we never find out. It would be so easy, and would make the bell so much more satisfying.

Just as a little fun fact, bi-metallic mechanisms are used basically everywhere around us. Most of the time not in the form a strip but in stamped discs that can be made to snap at a temperature with tolerances of less than one degree. Every item in your house that has a heater inside will most likely have a bi metal snap disc, as they are called, in them as safety mechanisms or every simple kettle that switches off when the water is cooking will have between 1-4 of these discs in them. It's actually quite fascinating how they work and how they are manufactured and actually how few companies there are in relation to the billions of discs used all over the world

Not only are they all around us to make tempurature based controls, but they are also found all over to make objects that do not change size in a single dimention. Its Really important in making pendulum clocks and thats the most likely place I can imagine a person would run into it. And thats why your grandfather clock has that weird pendulum made up of bars going up and down as the outside set expands pushing down, the middle set expands a bit more pushing up just enough to make up for the center bars expansion. Ok I gotta confess, making a new pendulum bar for an anitique grandfather clock was just my favorite project and I get too excited to share.

One of my favorite uses for bimetallic strips is car turn indicators. They use a bimetal strip wrapped in a heating wire to open and close the circuit, which makes the light blink. The famous clicking sound you hear in the car is the sound of this mechanism.

I can't express how much I love this. The amount of energy, time, materials and money spent on this, solely because you couldn't be bothered to use the timer function on your phone, is so out of proportion to the real-world benefit that it _has_ to be a pure labour of love. And I love that.

@@Pisolithus or the temperature in the surrounding air. It will cool much faster on a cold winter's day, he'd have to calculate the rate of cooling for every possible temperature. The amount of time the tea is steeped before letting it cool would also effect the cooling time. But with this, it will always alert him at exactly his preferred temperature.

Proper English eccentricity. A superb and beautifully made piece of silliness.

Amazing. I had just returned to my computer after filming, my coffee was cold and this video was in my recommended videos. Maybe google does know everything lol. What an incredible gadget, thanks for showing its construction.

All that build up, and we only saw one demonstration of the finished product, and even then, it wasn’t a live-firing situation, but a test run with just water! I need to see this a dozen times with real tea!

This is such a lovely piece of engineering and machining. It also demonstrates a physical phenomenon in a memorable and playful way.

One of the most satisfying parts is the way the ball bearing sinks into the foam after it's rung the bell. Very nice work!

This is the best thing I’ve seen on YT in a long time. I’m just starting to learn how to machine, but this transcends my ambitions to learn.

I almost expected Uri Tuchman to come up with something like this. A, sort of, pointless invention that still serves a unique purpose.

Fine craftsmanship. This channel deserves more subscribers.

This is way over-engineered, yet exactly the type of goofy mechanisms that humans love so much. Perfect. 10/10

I really like your style of video production. The smooth, calming, and well balanced voicing with the relaxing background music works perfectly witb the upclose camera shots. Wonderful job. I cant believe I'm only just discovering your channel!

It's like a Rube Goldberg machine. An over the top elaborately constructed and complex machine designed to accomplish a mundane task. I absolutely love it! I enjoy fabricating myself and can understand the delight one feels when designing and constructing such a device. One time I saw a group of engineering students who, just for grins and giggles, constructed a machine with over 20 different operations that took 50 seconds to complete. The machine was constructed to place a stamp on an envelope. Marvelous!

If you turn the inside of the bell (and a small part of the outside) first and then clamp it internally to do the outside there's no problem with the bell ringing. Did this when I made an about 300 mm "ships bell" in stainless as a wedding gift to friends some years ago. Do be gentle with the pressure internally though, the bell deforms easily but the setup is very stable as long as turning is made towards the chuck.. Sweet little project!

A combination of Uri Tuchman and Clickspring, awesome

Realy nice contraption. I first assumed it should be a tripod or similar but the cup edge holder worked out well. I do think you could use a soft spacer on the bell to make it less rigid which will increase the amplitude of the ringing

The videography and craftsmanship are just excellent, but I totally wasn't expecting an amazing maths lesson. What a treat this video was!

If you isolated the bell from the pillar, maybe a few pieces of soft leather, it would make a far more pleasing ring. That is a beautiful machine, with the most perfect English need for existing. Thank you for sharing your time.

This is the most beautifully overbuilt piece of kit for such a nothing problem. I love it.

Wow, it quite literally all comes together at the end. Bravo!

Love me some restoration of precision machinery. Knowing the quality of your work it is going to be marvelous I am sure.

As always, your videos are a relaxing break from the stress of normal life

Absolutely beautiful work as always. Thank you for the great insight and inspiration.

Wow , only a Brit would make this but also with great/quirky design and quality sir you have a new admirer and a proud Brit to see the talent that still exists in our country, brave.

Fabulous. Has Tim Hunkin been told of this lovely work?

Delightful. I never considered lead content in brass before, I assumed the copper component was the concern. Thank you

As a side benefit, the heat-sink properties of the mechanism will help bring your tea to perfect temperature faster!

This is such a beautiful piece of engineering and machining, thank you for sharing this with us ❤

Not only do I love the over engineering for a simple problem the quality of the video is outstanding as well

thank you for sharing your work!!

I image that producing this video was at least as much work as designing and fabricating the device. Excellent on both accounts. 👌

Fantastic contraption 👍. Love your videos, thank you 🙂

Doing something to help out those in need. Bravo! You're a real inspiration.

Amazing, every home should have one. Thanks

Great video as always. I feel like the ramp trigger is going to be very sensitive to subtle tilt variations on the edge of the mug, variations in table surface level, etc.. and ideally some trigger would be best to ensure consistent temperatures.

Brilliantly eccentric, brilliantly executed. Mesmerising from beginning to end. ☕️👏👏

that lathe is so nice. when i initially saw this video in my feed i thought it was a Technology Connections video, since theyve covered bimetallic strip technology so oftenly lol. i need something like this for my coffee

You could run a competition for the simplest mechanical or eletronic device that could do the same (maybe even the cheaper)

I love this kind of thinking and it is beautifully done!

Thank you for the inspiration!

Nice work. 👍 I like brass. We drink our tea from small, thin-walled tea cups in which it cools more quickly than in large coffee cups. Therefore, we don't have to pay attention to the temperature, but for us it is more important how long the tea "steeps" before you drink it. I come from East-Frisia (Ostfriesland), it is on the North Sea coast of Germany. We here are the *world champions* when it comes to drinking tea. On average, an East Frisian drinks 300 liters of tea a year. We East-Frisians have our own tea ceremony. "Prost Tee" we say. 😉 Kind regards from the North Sea coast 🦀

Для меня ваша работа одна из лучших на ютубе. Я сам токарь и не всегда чья-то работа за станком радует глаз. Но ваше творчество исключение.

A very unique way to ring bells is how we do here in the estate of Minas Gerais in Brazil. The bell is rung by an internal clapper have a huge conter weight. It's initially held upside down and then pulled so it turns. Each turn it rings twice. After that it can either be held upside down before being "turn" again or be pulled for a faster rithm ringing. I'd like to leave a link but KZread doesn't like it .-.

Excellent video! Your cinematography is top-notch! (And your machining skills are very good, too.)

Woau, dude. Pure magic!!! Amazing work!

Utterly relaxing and out of this world!

That is THE cutest drill press I have ever seen!!

Beautiful. I wonder if the bell's mount couldn't be altered to allow it to ring in a less dampened manner.

*This is Therapy For Eyes✨*

You could have the strip release a watch spring and have the arm of an attached escapement hit a bell. It'll ring instead of dinging but it might be nicer than a loose ball

Beautiful! Good use of human ingenuity.

Really neat! Thanks for sharing, don't know if I want any brass whatsoever in my tea water though.

Love it I’m a big rube Goldberg fan so this one ticks some boxes for me. Next time you do a bellish shape like that machine in inside first then fill it with hard meltable wax the outside won’t chatter as much you just have to be careful not too get it hot when turning.

In terms of brass or other copper alloys being used with food, my dad used to used copper cookware back in the day in Iran (copper cookware was/is used worldwide, just his personal experience) , but it was always coated on the inside with a thin layer of tin. This was because uncoated copper would leech into food and its salts were known to be poisonous. Tin is less reactive and less toxic (possibly nontoxic), and the intermetallic bond between tin and copper is pretty strong. Maybe tinning could be an option for food contact?

When I do knurling, I set the feed to ½ of the pitch of the wheels. That makes the spiral pattern in the knurl disappear.

Other KZreadrs: "We're gonna use an Arduino, Raspberry Pi, several LEDs, and a K-type thermocouple to make a tea temperature alarm." Chronova: Steampunk Heath Robinson Device.

Neat project! Given the ostensible purpose of submersion in a somewhat acidic liquid which is to be ingested, I do hope that the brass used is lead free, though.

Thanks Chronova, helps a lot!

Good old by metal strip. I have had to remake these for vintage honda motorcycles and their automatic chokes.

This is great! The homemade bimetallic strip makes me wonder what you could do with a DIY bourdon tube, perhaps a large, exploded view barometer.

this was how its usually done during the industrial age, however nowadays software pundits will be up in arms over all-mechanical temperature alarm... great video production, soothing music, clear narration and process explanation. highly recommended

I never knew that Heath Robinson used that level of precision!

Сложно представить более абсурдное устройство, но насколько же великолепное исполнение. Посмотрел на одном дыхании. Спасибо. Шикарная вещь!...

Towards the end of the machining I was thinking of all the ways I could reduce the part count and manufacturing complexity. Felt foolish when I saw how gorgeous and visually satisfying the final assembly is. Fantastic art that could only come from an improvised design, a skill I have yet to learn.

Fantastic! Thanks for sharing

Perfectly elegant.

An incredibly impressive and original project! Out of interest, are the small lathe tools with an aggressive top rake the way to go with brass? Or just what you had on hand?

@chronovaengineering

16 күн бұрын

Thanks! I often experiment with tooling, so what you see me using is not necessarily the best approach. For brass, zero rake is the way to go, but I don't usually bother swapping tools on the watchmaker’s lathe when switching materials. I was trying the aggressive rake for general use - I didn’t notice any benefit in steel (or brass) to be honest.

"prefect" :(

You really shouldn’t hard mount the bell but leave it free swinging on something like a spring where it can resonate and ring out like a bell should. Screwing it down tight dampens the vibrations and defeats the purpose of a bell in the first place. Other than that, nice work.

Copper and is alloys is usually tinned when used for cooking and storing food.

Quite pretty!

to reduce the parts count invert the bell and catch the ball in the bell.

You made great job and beautiful video thanks for this😎😮You are so talented mate

Wonderful! Could you put a spring under the bell to allow for more resonance?
