May I have a request for some particular machine called "Langmuir's method".
For reference:10.1038/1391066b0
It appears to be a 7 day trial.

I don't know if I'm more impressed by your ability to build/engineer or the fact that you can write straight without lined paper.
Fantastic is all that needs to said
Great gadget to be paired with the automatic tea making machine I must say
Think @colinfurze might need one of these because no doubt he’s forgotten a lot of tea during tunnelling:D
Fürze means farts in German
The Brits are summoning each other 😂
This is an exemplification of essential Englishness.
So british...
You mean briish
Terribly…

Wou you like a bit o' waer?

You can mount the bell using a sort of cushion so it will have a prolongated song and not just *ding*
Nice pfp
This was going to be my exact suggestion. The ding seems to small.
I was thinking a bell on a string.
A felt washer would help but point contact would be better
like how cymbals are mounted
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
Same thing with drum cymbals!
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.
@@AnonymousAnarchist2didn’t know that about the clocks. Bi-Metalls are fascinating!
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.
You cannot simply expect a man to set a timer, what if he uses different mugs and cups that will change the time it takes for the tea to cool
@@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.
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!
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.
Proper English eccentricity. A superb and beautifully made piece of silliness.
A deceptively simple mechanism with an exceptional amount of thought and work put into it... I love this.
...und außergewöhnlich viel Freizeit...🤔
This is such a lovely piece of engineering and machining. It also demonstrates a physical phenomenon in a memorable and playful way.
Fine craftsmanship. This channel deserves more subscribers.
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!
I almost expected Uri Tuchman to come up with something like this. A, sort of, pointless invention that still serves a unique purpose.
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 Therapy For Eyes✨*
As always, your videos are a relaxing break from the stress of normal life
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!
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
This is the most beautifully overbuilt piece of kit for such a nothing problem. I love it.
The videography and craftsmanship are just excellent, but I totally wasn't expecting an amazing maths lesson. What a treat this video was!
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.
*_This is soo Relaxing…_* *😌*
Love me some restoration of precision machinery. Knowing the quality of your work it is going to be marvelous I am sure.
You could run a competition for the simplest mechanical or eletronic device that could do the same (maybe even the cheaper)
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
Brilliantly eccentric, brilliantly executed. Mesmerising from beginning to end. ☕️👏👏
Delightful. I never considered lead content in brass before, I assumed the copper component was the concern. Thank you
Wow, it quite literally all comes together at the end. Bravo!
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.
Doing something to help out those in need. Bravo! You're a real inspiration.
This is such a beautiful piece of engineering and machining, thank you for sharing this with us ❤
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 🦀
I love it. I adhere to the comments regarding improvements to the sound, and I'm curious to see what will you make to put it after it's used 🍵
Fantastic contraption 👍. Love your videos, thank you 🙂
Excellent toolmaking with very fine ideas. Hats off.
You have way too much free time.
And I love it!
Amazing, every home should have one. Thanks
Excellent camera work and a neat build.
Absolutely beautiful work as always. Thank you for the great insight and inspiration.
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.
Great little project! One of these days, I'll be browsing your videos, and you'll have invented a working time machine with full build instructions.😂 I can't wait till that day comes! 😁👍
That is THE cutest drill press I have ever seen!!
As a side benefit, the heat-sink properties of the mechanism will help bring your tea to perfect temperature faster!
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
Absolutely stunning work.
thank you for sharing your work!!
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.
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
Серьезные вы ребята как я посмотрю 👍
Really neat! Thanks for sharing, don't know if I want any brass whatsoever in my tea water though.
Excellent video! Your cinematography is top-notch! (And your machining skills are very good, too.)
An interesting design and build. Thanks for sharing it.
I love this kind of thinking and it is beautifully done!
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.
Beautiful. I wonder if the bell's mount couldn't be altered to allow it to ring in a less dampened manner.
Gives a whole new meaning to "My God, he loves his prefect cup of tea!" Thank you for these very interesting pieces of engineering!
"prefect" :(
Beautiful!
Good use of human ingenuity.
Thank you for sharing this!
Good old by metal strip. I have had to remake these for vintage honda motorcycles and their automatic chokes.
Thank you for the inspiration!
I never knew that Heath Robinson used that level of precision!
Love it! Next step is the heating device to maintain 54C if you are called away for a while!
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 RUclips doesn't like it .-.
I love this! If you’re not already a member of the Dull Men’s Club you should be! They’d lap this up over there!
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.
Next: A whole video about bell making to improve the sound!
And make for a long, clear, resonant ring.
Other RUclipsrs: "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.
Woau, dude. Pure magic!!! Amazing work!
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.
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.
to reduce the parts count invert the bell and catch the ball in the bell.
look forward to your new lathe refurbishment videos 👍
lol, Now make one that rings when my beer gets too warm
Thanks Chronova, helps a lot!
The very thought, hint, of using a common *screw*, when you can, instead, machine a tiny and elegant *rivet* !
There's our crew!
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.
Bro! Indicate your parts every single time, it's just good practice and helps covering mistakes. Even cosmetic stuff. Mistakes happen my dude. Its SOOOO much easier to machine yourself out of a bind if everything starts parallel, concentric and so on.
For the bell, hold the bell horizontal and the knocker above on a pivot. Drop the knocker past the outside of the bell, ringing the bell and then hanging below after. Use a PTFE washer for a little drag to stop the swinging with a little tuning? Making the bi-metal move past a cocked trigger mechanism (only activated one way) would solve needing to pour first.
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?
I love these kinds of "over engineered" items that are made for a persons very specific and subjective need..! Yay!!! 😄
More stuff like this, please... 👍
Sledgehammer to crack a walnut doesn't begin to describe this exquisite project. And it's adjustable for preference. Of course it is. When genius meets master craftsmanship! Now about that Norden bombsight......
the madman did it. he actually actually used the thermal expansion equation from physics class.
Perfectly elegant.
"When an object is useless, it becomes indispensable" ;) Fine work !
Awesome build.
Beautiful. That sweet spot doesn't come often, but when it does, the tea cup is drained.
Wonderful! Could you put a spring under the bell to allow for more resonance?
This is how Land Rover was born!
Copper and is alloys is usually tinned when used for cooking and storing food.
Brilliant!
I would have thought that a thermal imaging camera interfaced to a computer and klaxon would have been better but the machining would have been rubbish.
Some super machining here, thanks for the video.
A lovely art piece. The mug should sit perfectly horizontal and one must be careful not to drop the ball in the mug; not a problem for a perfectionist.
Fantastic! Thanks for sharing
Brilliant bit of kit :)
well done, thanks for the video
Quite pretty!
Sir, what in the world is your job ? I'm a newly graduated mechanical engineer and i'm stuck behind a computer all day long, working for a big company, doing what needs to be done in the same way anyone would do. I can only dream about an activity such as what seems to be yours : Equations, manual work and creativity. How did you achieve this miracle ? How did you start ? Is it social networks that makes it financially sustainable ?
Great video, great build.
*YOU'RE A GENIOUS, SIR!*

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?
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.
@@chronovaengineering Many thanks for the insight! Needless to say, I'll be working my way through your back catalogue 👍
