Amazing Technique With a thread drill on a lathe machine, it is difficult to make worms

Кто хочет, всегда найдёт способ. Без конца можно смотреть как эти люди работают. Молодцы.

Been a tool and die maker all my life. This guy is brutal but the standards must be low where he is. Surviving any way possible.

Ive never seen a worm gear made like that before 10/10 top job for that one guys 😁😁👍👍

Amazing skill. Was a machinist for 20 years and have never seen anything like that. Notice he never used an indicator.

Первый раз такое вижу, молодец👍🏻🤝🏻

When doing this sort of work, how do you know that the diameter of the workpiece matches the thread pitch? I can see a situation where the next turn will not quite match the previous thread and you'd get a real mess.

Теперь понятно кто камасутру придумал.

Hats off. Yes primitive but it worked. Doesn’t mean we should approach every job in this way but we should appreciate skill and ingenuity and show our respect.

I always liked cutting brass on the lathe. I makes chips just like cutting cast iron. You don't need a chip breaker cause the nature of those two metals makes it impossible to make stringy chips like 304 stainless. I don't put anything past these guys. If it needs to be made, they WILL make it.

Lots of chatter and movement but damn sure worked. Necessity is the mother of invention.

It is fascinating to see that how a simple technique can produce complicated parts.

This is the kind of innovation I fear that American machinist are losing with the computer generation. Great job dude.

I've done this in 80s with manual milling machine. Just like you I brushed chips away but used also cutting oil.

I'm normally very critical of videos by shops such as this, because of the horrendous working environment and the total lack of anything resembling safety. My other pet peeves are when they hammer on parts in the chuck and welding on parts using the lathe as ground. Both of those habits tend to destroy the internals of these machines. That being said, this technique is very creative and this operator should be commended on his "out of the box" thinking. I suspect this was a demo as the part has no reasonable function as-is but nice work anyway! Now keep the damn hammers away from the machinery and if you have to weld on a part chucked in the machine, clamp it directly! Take care of your tools and they will take care of you.

Как люблю я стружку цвета золотого! В бронзовый кругляк резцом я жму сурово! Фаски и канавки точу Я всё в размер , вот уже подшипник сидит как пионер! Метчиком зубастым канавку обойду , Вот какое чудо на пальце я кручу!

If you didn't have the right involute cutter to do this properly you could pre-shape the gear with a dividing head and a home made cutter that was just triangular in tooth profile to get the number of teeth and depth pretty much right, then you could use this technique to get the involute geometry pretty spot-on. Using it right from the get go is going to look alright but the geometry is going to be off, because the number of teeth will be set once the grooves start getting deep enough to force the following cuts to follow. Then as you feed into the tap your effective diameter reduces but the number of teeth doesn't; causing binding and leaving you with incorrectly formed grooves in the worm gear. Still, you make do with what you have and this would better than nothing.

Из 130мм на 80. Роствертол. Нормально. Страна багатая! Можна!!!

Странно что у этого токаря все еще по 5 пальцев на обоих руках. Особенно забавляет обмер посадочного места под подшипник десяточным штангилем.

I work on modern CNC lathes/mills and watching this while eating was not a good idea. I was so worried that something would go wrong...but it didn't. And it is neat to see how one can unleash their creativeness to do so much more than the less modern toolset initially allows us to believe. :)
