What you do, Gena is so interesting and enlightening. Entertaining also. Thank you. I was totally unaware of the hysteresis (is that is an accurate way to describe) or “stickiness” of a bubble. I never even considered it. I love learning that kind of lesson. Thank you.
I watched a video years ago about a simple DIY jig to grind vials for precision levels. Sadly, I can't find it, maybe somebody else can link it in. The details are fuzzy, but here's what I remember. It consisted of a strong beam as a base, 4 threaded eyes, and a straight round steel rod. The eyes were screwed into the beam at certain distances. The rod was put though the eyes and a glass tube symmetrically , something like this: eye - little distance - eye - more distance - tube (in the center) - more distance - eye - little distance - eye The height of two of the eyes were adjusted to give the rod a predefined bend. Grinding pastes were sequentially added to the rod and the tube was ground and polished with a fairly precise curvature.
I think that the angle of inclination of the ampoules was changed accurately enough for such an experiment, and some differences in the stopping points of the bubble are associated with some features of the inner surface of the ampoules, or are associated with the action of surface tension forces at the interface of the bubble and liquid.
For example, I intend to bring to excellent condition those worn-out machines that I have. Then I will be able to produce parts with a sufficiently high quality of processing. This is already some production possibility, obtained essentially from worn-out equipment.
Hello Gena, thank you very much for your videos. I would love to see you creating a 90° angle as precisely measuring squareness is always a challenge to me. Greetings from Germany and stay safe.
Hello! There are a few other things I plan to do before making the exact 90 degree angle. But its production is included in the mandatory program. I also hope that I will make material regarding the 45 degree angle.
On industry I dont know. But back in the day it was very simple contraption of a metal rod squished between centers jist enough to creare a slight bend radius a glass tube is shoved over that rod and then just lapped in a rottating motion with cerium oxide. Simple contraption to make in any garage. But yours seems to be more repeatable
@@romualdaskuzborskis By methyl, do you mean methanol? I've a bottle of the stuff and it's quite a thin fluid, I must say. Ether must be on another.... level. ;)
@@danielkruyt9475 eah, methanol or methyl alcohol (CH3OH). Its quite alright for most aplications. Ether however seems to be so much more fluid that it reacts more precisely (does not "snag" on glass surfaces) and quickly. Although I believe they stopped using it for import simply because its a regulated substance.
Дуже круто 👍 Виходить в нашої повторення результатів дуже високе. Англійська добре показала себе по чутливості, але щось в неї у зворотньому ході немає повторюваності. Але напевно гадаю усі вони добре викониватимуть свої функції. Дуже гарне випробовування, та дуже хочеться побачити той ваш новий прилад😊 Доречі у вас тут непоганий американський блогер в коментарях.
Доброго дня! Коли я переміщував одразу на чотири мікрони вверх та знову на чотири вниз, то була досить непогана повторюваність, та цей єпізод я не включив у відео, і так задовго. А при переміщенні на мікрон булька часом ніби залипає, та й при переміщенні на сотку трохи не стабільно, можливо сама геометрія поверхні така, але скоріш поверхневий натяг на межі рідини. Ще скажіть будьласка, про якого блогера Ви кажете?

Thank you! You understand well what deserves attention on TH-cam. This is a great and very useful channel. I've been watching it for a long time and subscribed to it for a long time.
Hello! Thank you for your support on Patrion! Because of the war, we now have difficulties, but I have more time, which I can use to create content for TH-cam. Only this work is associated with some expenses, and the channel still brings in insignificant income, it is barely a year old. It’s only the first month since monetization started. Therefore, I ask viewers who find my work useful to support me. Thanks again!
Is the English ampoule maybe measuring in Imperial measurements and not metric? Depending on how old it is, it could be thousandths or ten-thousandths of an inch per foot. I trained in mid 1970's, we had to learn inch and millimeters although I didn't work to micron measurements until about 1977~78. It's really interesting to see how measuring is done, the inspection department where I worked was 'off limits' to factory floor.
Hello! The division value on the English ampoule is 0.01 mm at a distance of 1000 mm. I bought this ampoule three years ago from the company that manufactured it.
It does work. I've tried it. I thought I have a photo of the PoC from years ago, but apparently not. My concept was simple: a glass tube, two identical pieces of aluminium, M3 threaded rod and nuts, and some gasket or plug. The Al blocks had a blind hole for the tube and a through hole for the rod, for each. The blocks on the ends held the tube and the rod parallel. With the threaded rod and the nuts, I pulled the blocks together. Since it was an offset force for the tube, it bent a little. I used a low quality glass drinking straw, and didn't bother buying a better tube. Good thing is, it has adjustable sensitivity. For thermal stability though, you need to use the same material for the tube and the tensioner (threaded rod in my test). Shouldn't be difficult.
Навіщо ампулу перекручувати на бік? Вона ж фактично має лежати строго розміткою вверх. Для цього, у заводських рівнів, є додаткова маленька ампула. Ампула - це сектор великого кола і вона має свою вершину.

Outstanding work, Gena. I look forward to seeing your new level realised in metal.
Oh and I'm suspended from the ceiling. Awesome video and amazing attention to detail in minimizing the errors you induce.

Your thoroughness is amazing.
Thank you for sharing your work Gena,, 👍🥰👍
another very informative video. your requests for informations demonstrates your deep curiousity ! my most sincere compliments !
This information is really welcome, thank you !
Testing the linearity of such levels is not easy but you managed it with great care.
Nice to see you back Mr Gena
I absolutely love your channel!!!
Your creativity amazes me!
Amazing to see what you can achieve with your home made set up.
The next time I need a shelf put on the wall I'll call you 😀
Stay safe.
simply fantastic. thank you.
Nice to see and very impressive.
So helpful content, thanks , base on your knowledge we can renovate our Ukrainians industry.
For example, I intend to bring to excellent condition those worn-out machines that I have. Then I will be able to produce parts with a sufficiently high quality of processing. This is already some production possibility, obtained essentially from worn-out equipment.
I applaud your efforts especially as you are doing it in a foreign language, i wish you and your country well.
Perfect video
That looks like a great design you showed at the end of the video, when you build you should polish it like in the model.
Thank you for your job. Wery interesting and high quality job
Excellent work Gena.
Very interesting test , thanks .
Дуже цікаво дивитись та слухати!

Also Chinese use methyl nowdays for fluid. But I know for sure that US/UK ether instead.

Excellent work! From which AliExpess supplier did you source the tube?
I purchased it a long time ago, more than 3 years ago, the information was not saved.

Unbelievable!!
Остался от отца такой фрезер. Хочу перевести на своей машине. Сколько весит самая тяжелая деталь?
Все вместе весит примерно 850 кг. Если разобрать, самая тяжелая нижняя опорная тумба, вдвоем можно "кантовать" по доскам. Наверно около 200 кило.
Interesting. How well would a slightly bent (curved) tube work?
Hello! All three ampoules I have been able to purchase have a barrel-shaped interior. Probably this design is simpler.
It does work. I've tried it.
I thought I have a photo of the PoC from years ago, but apparently not.
My concept was simple: a glass tube, two identical pieces of aluminium, M3 threaded rod and nuts, and some gasket or plug.

Good thing is, it has adjustable sensitivity.
For thermal stability though, you need to use the same material for the tube and the tensioner (threaded rod in my test). Shouldn't be difficult.
@@besenyeim At my level, the sensitivity of the ampoule is not adjustable. The inclination of the ampoule relative to the support legs is adjustable.

Щоб розуміти, ампула в середині= це бочкоподібна форма, чи зігнута трубка.
