@12.50 instead of "dig a ditch" you could describe it as "Broach a Keyway" which would be accurate.

13:05 The "ditch" is called a "keyway". ❤

Those look like 8" or 10 LL submersible impellers for wells. worked on a lot of those. LL, Low out put, LM, medium out put, HH, high output.

That accidental spill looks dangerous kudos for those whom make the work continue. I would really love to see the function of this product.

That balancing procedure on the lathe looks like completely just learnt from practice. Really fascinating.

Похоже что современные журналисты считают своим долгом врать всегда и везде. Ни одного репортажа без вранья. Даже если в ролике нет ни одного слова, то хотя бы в названии можно вставить враньё. Вот и тут... ну негде соврать, так хотя бы в названии... А далее эпидемия вранья распространяется, уже и политикам и чиновникам тоже можно врать и ни кто их за это не осуждает... Врать стало нормой... а у журналистов просто обязанностью. По сути это журналисты делают политику, это они создают общественное мнение. И владельцы изданий осуществляют селекцию по этому свойству, оставляют только тех кто врет всегда и везде, где надо и не надо... врет на автомате. Осталось только осознать кому принадлежат СМИ... Очевидно что это не случайность а такая политика.

Не верится, что эти технологии позапрошлого(прошлого) века существуют в высокоразвитой Японии.

A dust mask??

Used to work in the tool room for a foundry that poured bronze propellors for boat and ships. These people know what they're doing, and doing it well.

Не конг-фу, лет 50 назад так делали.

What squalor. The workers are not protected from spills of molten metal; they wear simple canvas clothing and ordinary shoes. The shape is made by clinical idiots, the upper and lower parts do not provide any rim for connecting or centering the insert, which, in fact, leads to streams of metal pouring onto the floor. People work constantly in a bent position, and I am sure that the vast majority already have back problems. What about manual bottling? Back in the Middle Ages, a ladder-shaped filling system was invented, which eliminates the need to pour metal from ladle to ladle; you just need to direct the stream into the chute... And yes, why do workers drag metal by hand across half the hall if the molds are on carts with wheels?! Do they have nowhere to spend their energy, or do they like extra work? What’s stopping them from rolling the molds as close to the oven as possible, so that they have to carry them less by hand, if they couldn’t make a device to remove the heavy weight from their hands? There are also big questions about the final product. Even in the video you can see that the gauge for checking the hole is loose. This shouldn’t happen, it’s already a size violation! And yes, the set contains 2 gauges - the one that should go through the hole, and the one that shouldn't. Testing with one caliber does not provide information about compliance with standards! This is a gross mistake!!!

I thought Japan was a high-tech country. but tna video. the process was done 200 years ago.

All that they give these guys is a K95 type mask-instead of a respirator-PATHETIC-bet they're dying off in their 50s & 60s

not that there is anything nearly wrong with the product but the safety standerds are appealing.
