That was really impressive. 🙏thank you. What other videos would take thousands of words and hundresd of theories You demonstrated in under a minute. Relearning the importance of practicals. Everything was so clear to see and understand.

This is extremely impressive, I love seeing other people make incredible DIYs. You must really love the stars 😅🙏

You have a very nice setup... I can only dream about that vaccum pump

I need this in my garage.

So clever to use a magnet to turn the mirror blank!

That is how most of these systems are made because you have very few options for a air tight connection. In ultra high vacuum systems the problem is actually helium atoms getting sucked through the glass.

That is awesome!

Nice. Thanks for posting. Can the mirror be overcoated with your present configuration?

Wow, good job!

FASCINATING!!!!!!! Thanks 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼

Great information thanks...I need to fix my mirror...

Excellent.

Excellente and fascinating!!

It is quite a complex pump. What is the minimum required vacuum pressure ?

Hello Luciano, thank you for sharing your knowledge ! We wanted to try to coat a mirror of 60 cm, how important is to rotate the mirror inside the chamber ?

Is this Silver wire? Or Titanium/Tungsten heating wire? So ist this mirror Silver/Titanium/Tungsten coated?

DIY plating would be nice

Hello I want to make a machine to make coating to my mirrors. You can help me with the parts I need to do something similar. Thank you

Do you know anywhere I can have things sent to do this? I have parts needing coating.

Spectrum-Coatings, Majestic Coatings, Owl Laboratories. These are first surface coaters. For a regular mirror, best just to buy a kit and DIY. No chamber needed but you do need a VERY clean work area.

Congratulations

Congratulations this is brilliant, What great work. I'm curious why does the aluminum vapor rise if the vacuum is present?

Its heat energy like water boiling. Al ion gas shoot off it metal because it has higher energy than it's neighbor atom.

Wow that's amazing. Thanks for sharing. Just a question do we really need vaccum or do we just need an oxygen free chamber? Can we fill the space with say helium and achieve the same result?

@tonystanley5337

Did you notice the effort he went to to create the vacuum? If you just have to fill with inert gas then that is what everyone would do. You need a vacuum.

Setup up two stage evap, 1) metal layer, 2) Carbon, what is deposits as a sapphire layer protecting the metal layer. Be careful with gold, it goes everywhere during evap. Where are you in the world? anywhere near Portland, OR, USA? I am a High Vac Design engineer....

@@wannabe8x6 Due to the oxygen in the air that will react to everything but also due to the air pressure it self that is to high so the aluminium vapor would not even reach the mirror and if something will be able to reach it the surface will be far from shiny due to severe oxidation of the metal on its way. The tungsten coil will also be attacked by the oxygen and tungsten trioxide would also be made du to this which is a yellow substance and also not shiny one bit. You have to get the right equipment so you can get down to at least 5-E6 Torr before even thinking about doing something like this. A turbo pump is expensive but easier to handle but absolutely nothing is allowed to fall down in it no matter the size when it is on so its very sensitive but it will not emit anything into the chamber like oil or such. The other thing to use is a diffusionpump (used in the video) that is much cheaper but require a special type of little expensive oil and a DP will leak small amounts of oil into the chamber that could be bad for what you are doing or not a problem. But you usually use a special type of baffle that prevent like 99.99& of any oil to enter the chamber that should be enough, otherwise you need to use liquid nitrogen or similar to really remove pretty much all of it. And with a diffusion pump so if a nut will fall into it, it will just go on like nothing happen. If the same would happen with a turbo pump at full sped you would run and the pump would also be totally destroyed after that, it would be a very dangerous situation. So they both have their pros and cons but one of them is needed to be able to do what is done in the video, and also a rouging pump.
