For someone who it 'not a professional' this is very impressive work. Grinding a mirror is simple but very precise work. Aluminizing a mirror is a quantum leap upwards in complexity. Congratulations! If you have friends who build their own telescopes, you may find that your standing as 'not a professional' may change when word gets around that you can coat mirrors. Thanks for the video.
I know this is a matter of semantics but quantum means small(subatomic), not big. I don't mean to criticize, just to inform. Marketing departments are confusing the world.
It looks complex due the equipment but is not that hard, I find figuring mirrors to be harder, you just need money and to live in a developed country so you can get second hand vacuum equipment for relatively affordable prices.
awesome job. one suggestion. instead of tungsten wire, use a strip of tungsten and create a small pocket in the middle. this way you can load the pocket with other materials more easily. as well make it easier to clean.
6:55 I have made one my self and one transformer is more then enough, a coil this size is glowing white hot, its all about the voltage. You dont need the thick cables you use, you need thinner which is totally ok since the current is not especially high for these coils and you need to get the voltage up to at least 5V or so by more turns on the secondary. I have 5.4V on mine which works for pretty much anything and I have also made a small electronic control unit so i can control the power from 0 - 2000W and thus dont need a big variac. But how the hell cheap was those voltage control transformers, variacs?! Like only $35? WTF!! They cost at minimum at least 10 times more! Dam..
Great stuff. That is one expensive hobby you've picked, vacuum equipment always costs ten times what it's worth because research labs have more money than sense. Two tips: 1. Always wear latex gloves, the more sweat you put into every surface, the longer it takes to pump it all out again. 2. You don't need anywhere near that amount of grease, just smear a little bit on the tip of your gloved fingertip and then pull the rubber seal between finger and thumb to smear it on very lightly. Only the part of the seal that is compressed does anything useful, any grease not on that part is not helping you.
Olá, você teria conhecimento de algum projeto em PDF para a fabricação de uma máquina dessas? Aqui aonde moro no Brasil é difícil de achar quem faça esse tipo de serviço. Gosto de astronomia e estou fazendo meus espelhos então se conseguir fazer uma máquina assim de pequeno porte seria uma grande ajuda.
6:12 Yea that will leak like crazy, it should be mounted the other way around. And PLEASE use gloves! You contaminate everything you touch with oil from your fingers which makes it much harder to reach full vacuum, if at all.
How did you figure this all out? Is your work somehow related; machinist, physics, lab, ...? Or did you start with no experience making anything and do this? If so...pretty incredible (incredible anyway). B.t.w. how did you know that a 6mm acrylic dome would be strong enough / safe to use for a high vacuum?

6mm Acrylic dome is not calculated, just speculation may be useful. If damaged, can be custom made another 8mm Acrylic dome Anyway Made in China is very cheap.
One transformer is more then enough for that coil, I know since I have done the same but I made an electronically controlled instead so no need for a variac and pretty much doesnt weigh anything either and take much less space. You have way to low voltage, the higher the better but within reason of course. I have wound mine to output 5.8V and that is enough to make a coil like this to glow bright white with only one transformer, 1.8V is way to little for this length of coil.
@@SmeeUncleJoe 3 years late there but oh well; they were unfortunately not written down but I think ST electronics has an AP (application note) with a schematic that after little tinkering with can be used to control a big transformer, and that was what I used.
If you mean the round type so would it be a gamble since they are made of ordinary glass and are not precision made and contain stresses in the glass that one day can make it break and implode under high vacuum then and throw pieces of glass all over with speed that could seriously injure you. So it might work but its highly not recommended.

that mirror is so cool and clear, for a moment i honestly thought that at some angle, i'll see me in it.
What a beautiful machine! Well done.
Looks like my CoreXY 3D on steroids - fantastic work
You inspire.
What pressire need for aluminizing ? Thanks for the video.

Tungsten tel yerine normal resistans tel elmazmı
How about a silver coat with a tarnish proof coating?

@Learnkalaa Whatever works for you. :) I want is small and light and nothing that wears out in the end no matter the load.
you are not profesional but you are a master...
Why it's better than chemical Mirroring ?
Where can I purchase these components other than ebay? Alibaba is for bulk quantities only.
*É sempre necessário ter a bomba à vácuo para realizá-lo?*
Sim, senão não funciona a metalizacao...
Whats the code for the diffusion pump like the other parts I can't see the code thanks.
Is there any reason why a welder would not make a good power source?
Hi Luciano ! do you think that with the same machine you can also do anti-reflective treatments?
What chemical that used for anti-reflective coating?

What metal was on the Tungsten (W) wire that melted? Was that to verify temperature?
Aluminium is the metal on tungsten or cromium, they use both to aluminize.
Silent movies went away back in the 1920s !
I feel it's better than most videos with useless music that would put you to sleep.
蒸镀机还能用吗
Good job, keep it up.
三年了，那家店铺已经没货，早点看到up主的视频就好了😂
Great workmanship.
Hi ... How much I appreciate the drop in pressure I got in this ... If I asked you for help you could help me out
So interesting it took like a minute to aluminize it
6:12 Yea that will leak like crazy, it should be mounted the other way around. And PLEASE use gloves! You contaminate everything you touch with oil from your fingers which makes it much harder to reach full vacuum, if at all.
gR8 Job Bossman! AMAZING!

I am not clever.I just use Google search powerful knowledge base to building this vacuum chamber
wow. You might be wrong--you are clever.
I agree! This is *VERY* impressive work! I missed how the rotating table works though. Can you explain please?

The ring is driven by the motor. you can click the link to see

Anyway Made in China is very cheap.
I would have not used the DC grease on the O rings, the pump oil is much better, in terms of vapor pressure

Can you link to your plans ?
@@SmeeUncleJoe 3 years late there but oh well; they were unfortunately not written down but I think ST electronics has an AP (application note) with a schematic that after little tinkering with can be used to control a big transformer, and that was what I used.
I take it you mean KILOvolts and not volts ?
@@SmeeUncleJoe Nope few volts, you need a lot of current not so much voltage.
The video is difficult to see the name of the product. You can show the link?
How to find diffusion pump Taobao.com?
Thanks!
Foreign countries can not see the second-hand goods in Taobao.com
Taobao only use the Chinese input to find.
You can only go to looking for eBay
Are you making this in Macau ?? It's amazing ..... I just know Macau = Gambling ...Very Cool man
This is fantastic!
Increíble, felicidades
No sound!
Great video sir
could you upload the link of the pieces please
Hi, can i build a aquarium as a vacuum chamber. In my town and around, there is no vacum chamber to buy. please answer me.

Agreed. DO NOT use an aquarium...lol.
awesome video thank you
👍👍👍👍👍👍👍
Thank you !!
Very cool bravooooooo
thamk you so much great
Who can coat a small mirror for me?
Thank you
impressive
Que loco!
nice !
Congratulations, you would have the complete scheme of this project

Here's how you do it if your mirror is a little bigger :-) ruclips.net/video/h4FBKbNY258/видео.html
