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 😁😁👍👍

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

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

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

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.

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.

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.

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

Первый раз такое вижу, молодец👍🏻🤝🏻

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

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.

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.

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.

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. :)

Fantástic Job congratulations, God bless you

If you need some shims to put under the Turning-Tool, try and obtain them from an old transformer, I find them very handy.

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

The circumference of that wheel needs to be precise in order for those threads to be continuous

Good idea. The main advantage is that unlike gear hobbing no drive need to be given to work wheel which macks the machining simple. However required profile matters. Idea can be useful for repair work where spares are not available.
