Watchmaking: Machining a 0.6 mm Screw

I'm no machinist, just someone who enjoys watching machining videos, so when it started with the raw stock I was like "that doesn't look like such a bad scale to work at, a little small but not terrible", then you turned down the diameter and I just went "OH, I see..."

I half expected him to cut the threads on the lathe using the automatic feed. This is much more sensible.

No, thank YOU for watching.

All of you horologists are nuts, looney, insane.
After 25+ years as a jeweler, my respect for the lunatics of mechanical precision never fail to put a smile on my face.
Nice vid demonstrating the machining of a small part.

Wow! Amazing process and procedure.

Are there torque specs for fasteners this small? I'm curious

You EARNED my subscription with this. Wow

Thank you for these amazing videos. I look at my watches in increasing awe with every video I watch.

Amazing. But how on earth do they make the die? Presumably with a tap... er

I know nothing about any of this except "what a screw is" and this was extremely fascinating. Thank you

Great skill and patience, well done..

Iphone screws be like

Who made the 0.6mm die?

Amazing 💥

i thought i was going to see how a tiny screw was made, but instead i wonder how the die was made.

I spend a lot of time also looking for lost components only mine are about 10mm diameter

And all in a 5 minute video! Thank you for not dragging this out for 20 minutes.

It's a lot more fun drilling down the centre of a 0.6 hard steel screw thread that has snapped off.
I use a 0.3 drill for that.
WD40 is a good cutting fluid for tungsten drills.
Decant some and apply with a 000 sable brush.

So interesting!

The tolerance on that has to be amazingly small.

The parting tool is ticker than the part it is cutting off... :O

Screw it!

Adam Savage sent me! Glad to be a new subscriber 🚀

"woops, dropped it"

next week, how they made the die.

I just enjoy watching machining like this. It's so fascinating.

No, thank YOU for "watch-ing"!!

What kind of watchmakers lathe are you using?

What lathe is that? And is it possible to find something similar? Possibly with the stock feeding from the guide bushing? Like a swiss lathe

I am so glad I found this channel! It has been something I have been wondering for a long time as to how watchmakers make such tiny parts.

Fantastic.

Ok,,,,now I want to know how the die is made.

I honestly expected some review of obscure French bolt action rifle when I saw the thumbnail.

Hah! I've been into audio for quite some time and I've always been thinking the M2.5 screws used to mount a cartridge were small!

WHY SCREW IS SO NICE?!

Amazing information. Can I please be directed to a chart I can use for diameters when cutting such small threads. I am at a loss.

You can get watches for $10

Hello buddy or you do not know what is the name of the lathe from my last video I'm looking for information. Best regards

Great stuff.

This is what inspires me never to go into this field. I couldn't imagine spending hours meticulously working on making one screw. I'm happy enough being a consumer of fancy watches

Amateur...

I keep thinking of John Harrison doing this in the 16 century and won the Longitude Act prize. Those were the true genius

How on earth did they make these in the 18th century

Thank you for watch-thing

I'm a retired Machinist and watching this I have such a great respect for those that tackle things this small. Incredible. Above Excellence. My hat's off to you sir.

Brilliant work, 👏

Well dip me in s*** and call me stinky if that was pretty cool

New study finds that the average human eats 10 of those in their sleep over their lifetime… 😂

How was this done 150 YEARS AGO?!
