I finished the glass molds. F project | EP#7 

The whole CNC sequence is like a thriller )

Impressive! Re-creating the lost technology several decades old. I'm damn impressed. That's some nice CNC action.

Now *this* is craftsmanship, 👏🏼Bravo to you and your team ! 🎉

Amazing work. You guys are building tools that will last a lifetime too... Don't forget that, it will live on long past we do.

WELL DONE for your first prototype, there's a lot precision features to deal with . Don't worry you will get better and faster has the time goes and build up real good skills in TOOL AND DIES MAKING :) Can't wait for your next vid the suspense is killing me :)

The surface finish you are getting from the CNC router is very impressive!

I am getting extremely excited seeing this progress! Well done!

Nice ! Can't wait for the molten glass ! Thanks a lot for these videos !

Thanks again for the video Dalibor!

The crash at 8:35 was, uhh, impressive

Amazing work! Great tolerances!

That is some phenomenal machine work…my grandfather was much like you with that sort of thing. He was quite an amazing machinist…and I wish I could’ve learned more from him before he got to where he couldn’t do it anymore!

It's looking really good! It also looks like you fixed some of the previous runout.

I will never not be amazed by the absolute precision and work that goes into making mechanical parts and machining in general. I've had some interest in making some projects for myself (like figuring out a way to make a modern day reel to reel tape machine with greater playback speed precision), but that's maybe for another day as that requires a lot of learning, nevermind the money. In the meantime I'll appreciate the work that others like you do, lol.

Super exciting to see this come together finally!

So excited to see this thing in action!

great progress, thank you for the video.

If you use a spotting drill, the point angle is greater so the normal drill bit will always end up in the centre rather than a 60deg drill where the entire surface of the 1mm drill flute is coming into contact with the surface which can lead to wandering.

Crazy stuff, love your work, love you. Thank you😊

Beautiful work

Wonderful progress and nice machining!

Paráda Dalibore 👍

Such a satisfying snappy ending! 😂

Хорошая работа. Очень хорощий и точный станок.

This is absolutely brilliant, well done. I can't wait to see the next part and a finished working tube.

It's supercool to see it made. Also, supercool that there's almost no cantering play. Do you plan to polish the mold, btw? As to the play of pins, as it's tiny, you may consider electroplating the mold (it would shrink holes tiny bit only and add a mirror finish). But it's an overkill as with all my suggestions :D. Can't wait to see it being tried with glass.

craftsmanship to its finest. amazing project.

Woo! truly nice precision and the contraption works like you thought it should pending molten glass. congrats.

Looking good. My only concern would be needing some draft angle on the side of the top half of the mold for extraction. I tried to cheat on the molds I was working on last time I wrote and ended up with the pressed piece stuck in the top half of the mold. Also you may need an ejection method on the top like you have on the bottom as its a 50/50 chance it will get stuck there too. It will eliminate the risk of pulling from the exhaust tube to remove the part which increases risk of breakage. After my setback on the wafer mold I turned my attention back to by 7 pin flat press stem tool and completed it. I made a few test parts but they wound up overheated and I need to rig up a different burner arrangement for more consistent results. Also I need to improve the flare holding clamp as they tended to be pushed one way or the other during pressing making crooked flares. Otherwise they seem to work with either 3 part dumet or nickel-iron leads equally as well. Once I can make them consistently with a minimum of expiative phrases I will try to make a video.

Great work 👏

Congratulations. Empirical engineering at its best.

Very cool!

So cool 🤘🏽🔥

looks promising!

Glass forming with machines is something I wish was more often talked about in the maker community. I guess its because glassworking has a kinda high financial barrier of entry. Hope that changes in the future.

nice! ❤

very fine.

Beautiful work as always! BTW shouldn't this be episode #7 🤗🤗

👍thank's🙋‍♂️

What alloy are the tube's pins made from? Tempco of expansion would be a big deal. Has to be malleable enough to prevent excess leverage stresses where the pin meets the glass.

Wonderful design and beautiful work! But why does it have to spin? Wouldn't the mold work just as well in a static mount? Also, you don't need pecking on cast iron because chip evacuation is excellent as you saw.

Just melt some glass already!

Очень круто!

Are you guys shooting cold air on the bit instead of coolant?

Could you put a GoPro on the spinning part of the mold to see the action more clearly?

круто! часы бомба, где бы еще найти 200к на них))

Will you PVD the piece in platinum? Platinum really doesnt stick to glass. You can make glass biscuit with a platinum mold, the glass just pops when cold

12:24 **Interstellar docking scene music starts playing**

Just a suggestion. Instead of guessing the speed. Check the manufacturers recommend feeds and speeds. Also. Smaller carbide mills in steel typically like a lille coolant/lube. Dark cutting oil does ok. It helps with chatter more often than not. Absorbs some of the energy and helps to reduce drag in the cut. Also helps the bit last much longer.

How do you keep the glass from sticking to the steel? Treating the parts with graphite powder?

Do you plan on making triodes in the future? 😯✨

Machining always starts off absolutely terrifying.

Dammit, no glass!

What is that red sealing coating on the pins in the area of contact with the glass?

why dont you use a battery powered screwdriver when you move the machine vertically instead of handcranking it (11:48)

They are doing this kind of cnc work in high schools now.

Is this a standard vacuum tube socket size?

Why you have mounted the mould on the lathe ? Is there any particular reason ?

A work of art, after watching I needed a cigarette

Круто! Я в России , у нас ещё склады СССР не оскудели. ИН4 покупаю за 400RU. Все заводы ( в том числе и "Светлана" - ламповая техника 6П14П и т.д. ) пошли под нож😢😢.

Absolutně jsem nepochopil na co se tato věc využívá. Mozna to je mnou, protoze jsem cele video proskákal a mozna to take ve videu bylo řečeno. Ale stejně by mě to zajímalo. :)

Ok, but how in the world did the create it back in the.. what? 50's?

А разве нельзя использовать для переворачивания станка акумуляторный шуруповёрт или гайковёрт? Это было бы быстрее и легче.

What is F project?

Could you please enable autogenerated captions for this video? Thanks!

This man is very busy, you wait forever for a reply by e-mail.😅😉

I'm disappointed, I expected some swearing in Czech a couple of times!

Promo'SM

OMFG, I'm doing PLA 3D printing tonight, and it's not going well, and y'all are FREAKIN ME OUT..... lol Wait, WHAT? I Have to WAIT for glasssssssss???????????????? holy hell, back to my stupid plastic....

You are bringing excellence back to the new work force and away from that Chinese rubbish
