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

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

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.

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

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

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

ماشاءاللہ استاذ 😅

Первый раз такое вижу, молодец👍🏻🤝🏻

Muito bom amigo, vcs são demais Parabéns!!!!👏👏👏

Wow, you make it seem so easy👍👍👍

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

I am impressed the shop isn't filthy and the lathe hasn't been beat on and abused great work

Fantástic Job congratulations, God bless you

I did the same thing ina milling machine. Just turned up an Arbor out of bronze for the piece to rotate on and held it horizontal in the vice jaws, that way you can use the X feed to also cut across the whole surface, not just in the middle.

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.

🤔интересный приём 👍

Fantastic skill by being versatile.

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.

Ingenious, I've never seen this before.

Hola siempre veo tus videos ingenioso tus trabajos te felicito !! Jorge , Santiago de Chile .
