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.
Can't believe nobody name dropped @TechnologyConnections with this comment, nearly every other video they put out is focused on a bimetallic strip powered device.

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.
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.
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 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.
The beautiful craftsmanship, design, and camerawork for something that is frankly a ridiculously over-engineered solution well earned my subscription. More please.
The whole concept of this is superb. There’s a narrow window within which tea (or coffee) is optimal, just nestling between scorching hot and too cold. To hit that perfectly is ideal, and when it’s with such a beautiful item, that’s just perfect!
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!
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.
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!
The amazing part to me is he solved so many steps to come up with something simple. How to hold it on the cup, how to move it at the right temp, how to keep the ball from flying out so on and so on. Whats it for? To tell when the tea is the right temp. Great Video loved it.
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
I'm absolutely intrigued watching metal machining, but especially fine machine work like this. Awesome. In the end, first, it's beautiful. Second, it has the design of a Rube Goldberg machine. Love it.
I love when overengeneering does not imply using AI to replace an IF statement. This was a fascinating watch. Definitely worth suscribing for more. Thank you !
Well that is totally bonkers but you earned my subscription with a great quality and peaceful video ! I love it when I find a new channel that gets it right with no flashy gimmicks or attention grabbing nonsense !
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.
It is cool that temperature sensing can be done mechanically. I think this entire mechanism could be miniaturized other than the bell. Wind a miniaturized bimetallic strip like a clock spring, solder a heat pipe going to the mug to the inside of both the bimetallic strip coil and its thermally insulated brass case, and use rotation of the outer part of the spring to lift a detent on a sprung striker that will hit a stop and spring forward to hit the bell once. Then it has no orientation needs and can be made similar form factor, albeit larger, to a meat thermometer with a bell and striker attached.
Wonderfully fancy for a small task, love it, the day i i'll be good enough to take this out of myworkshop i'll be super happy ! Thanks for inspiration and sharing !!
I watched this video when it first came out, and just watched it all again. This toy is just SO over-engineered that it is just about perfect. I would have done the job with an Arduino and a temperature sensor, but this way is so much better
Nice, a channel with good music and narration. A soothing Bob Ross quality, but making happy little mechanisms and not trees. Also, the entire narrative of an intricate solution to an age-old problem of tea's gone cold.
An alternative bell ringing mechanism: a cam with a strong spring in a bistable arrangement. The cam rotates *JUST* past the point where it locks so that it's on a hair trigger. A set screw can adjust this. The bimetallic strip then only has a tiny trigger force to overcome before the spring starts to accelerate the cam and a hammer on its other side strikes the bell. No loose parts to lose, it works at any angle, and the process of priming it is simply rotating a knurled knob.
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.
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 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.
That's crazy spending so much time making this device, I could have made an electronic version using a small microcontroller in less time. but I loved watching you make it and it looks great...
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... 👍
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.
I always wished I was British. There's just something about you guys' energy. Seems like you guys just have it figured out. Living and being content. Idk I can't really explain it haha
edit: I just heard "When I built my vertical high speed drill... in the sterling engine video. 🙂 (1:22 - maybe someone could help me with what drill press that is? Maybe it's a converted hand cranked one?)
What a great little invention! The only part that I thought was a bit lacking was the ring of the bell. I suspect it might ring a bit clearer if it was sat balancing on a pin instead of screwed on tightly.

Beautiful crafted. A more robust method could be to use a clock spiral spring to pre load an arm that is released onto a bell. A trigger from a deflecting bi metallic arm. That was the cup does not have to be perfectly flat and the sound greater with more potential energy available.

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.
😮@@Vyv-z9n
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.
Please make a flying tourbillon 🙏🙏🙏🥰🇨🇦🏴⚓
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.
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
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.
Also, don't screw it too tightly. Leave it some room to vibrate.
If Wallace and Gromit were into machining, this would be their first project!. Lovely project, masterfull cinematography, good narration👌
Closely followed by a cheese portioning and dispensing mechanism!

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

Yes, *_HUGELY_* disappointed about that.
And wot about the milk, hey!
the madman did it. he actually actually used the thermal expansion equation from physics class.
This is way over-engineered, yet exactly the type of goofy mechanisms that humans love so much. Perfect. 10/10
Yes! Us humans love things like this! Tell me more about things my fellow humans enjoy.
A deceptively simple mechanism with an exceptional amount of thought and work put into it... I love this.

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!
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.
As a side benefit, the heat-sink properties of the mechanism will help bring your tea to perfect temperature faster!
And he better not dillydally after the bell rings!

I almost expected Uri Tuchman to come up with something like this. A, sort of, pointless invention that still serves a unique purpose.
Love it! Next step is the heating device to maintain 54C if you are called away for a while!
As always, your videos are a relaxing break from the stress of normal life
This is absolutely one of the coolest things I have ever seen!!!
The videography and craftsmanship are just excellent, but I totally wasn't expecting an amazing maths lesson. What a treat this video was!
A very pleasant video to watch on a Saturday morning.

When engineering skills and art are combined, innovation thrives, and beauty is born.
I initially thought the bell would ring when it was getting below an enjoyable temperature. Amazing work.
what an awesome build! i could watch you machine all day, your channel is amazing!!
Quite insane and totally mesmerising! Thanks for the video.
I image that producing this video was at least as much work as designing and fabricating the device.
Excellent on both accounts. 👌
Now THAT'S taking your tea seriously! What an excellent idea! Very pretty build!
England thanks you for your important work, we hope you will be remembered in the New Year's Honours list.
Absolutely beautiful work as always. Thank you for the great insight and inspiration.
This is some real Wallace and Gromit style domestic innovation. I love it. More please!
Beautifully over engineered solution to a requirement..... so enjoyable thank you
