Would a roughing pump be strong enough for a radiometer?

I have a pump that i need an adapter for the top of the pump do you have a email i can show you a picture of that i need maybe you can put me in the right direction

What size caps did you use for the tips 🤔 I'm looking to get some

This is amazing tbh, tubes are a niche demand these days but I hope one day you make a very large and profitable factory.

underrated video.

Man, actually, i love what you are doing🥹 we should need someone crazy with tubes like u to buy snd start again a tube factory 🥹

Would there be a problem with cutting or melting the pin bases off of unusable tubes ?

Now I understand why all labs with cryo and vacuum look like metal pipe spaghetti. All labs in general really when you lay it out piece by piece, purpose by purpose. Great way to show it, sir.

YATTA!

Why didn't you make it solid core? It's more secure for an exterior door.

I love Tube....😍🥰

I will be using an old PVD system and this video helped me a lot, thank you

If you don't care about color you can get phosphor from fluorescent lights

Shouldn’t 0.4-0.8 mm be nm being that it corresponds to pore size?

O2 PSA systems for home POC medical use typically have a max capacity of 5 LPM. Some go up to 10 LPM. Why don’t they require drainage of condensate?

In the 1980’s I worked as a consultant for Kaldair, a venture subsidiary of BP. It sold refinery flares and PSA nitrogen systems for inerting. Both product lines evolved from BP’s oil producing needs. The adsorbent was a type of pelletized coal from Germany. The idea of using product gas to purge the exhausted bed was discovered by an intern by accident. The small amount of sacrificial purge gas raised product purity about 5% to 95% at virtually no cost.

Your ability to articulate all this deep tech; like you are a driving instructor; is a super power.

New CRT monitors when?

At 6:50 you state that both valves are closed. But the bottom valve is a two position valve that is either pressurizing or venting on the Oxikit design.

Put the waste stream into a big gas centrifuge to get argon. Or would the argon pass through with the oxygen?

‏Excellent build , thanks for sharing, (waiting for new videos)

The chain looks a bit sloppy, introducing hysteresis between the multiple claws. Meaning the glass tube becomes off centered.

Have you ever heard about a Nuvistor tube, like the 6CW4? These are actual triodes the size of a large transistor and look like a transistor too. I never knew they existed until I tore down an old tube receiver and found a couple of them. I thought they were just large transistors, until I googled the part number. I think this is the way tubes would have gone, if they were still made in some alternate universe. Maybe they would even be able to manufacture tiny tubes into an IC chip, lol. I heard, but I'm not sure if it's true, some tubes are still used by the military because they aren't effected by an EMP. I wonder what they look like.

Great video, really clear useful information! Thanks.

Turbo pumps are not that sensitive to spurious volumes.So if the tube was at ambient, I'd slowly open the valve to the turbo.The turbo may slow down for a few seconds... As long as it doesn't start screaming..

i use a medical one to run a bunch of fish tanks it works great

Your fireplace should be fully enclosed with an air intake pulling oxygen to feed the fire from outside through an intake otherwise you are just pulling any hot air from the shop into the combustion chamber creating a vacuum in your shop that in turn pulls cold air in through any air gaps in the building in an endless cycle self defeating cycle. Fix it and that little shop will be super hot with 1/10th the wood.

Awesome thanks!

GREAT VIDEO!!!!!!!

17:51 You can see and feel the happiness, that he didn't forget the nut..

Take the too simple design and make make it 4 step half pyramid pushing the middle support flat opposing angled pieces ribbed to add a soft silicone or something to cover the supports inside so the binding and wobble areas are fixed in a matching level twin linear opposing lathe chucks so the blow tube can be used with a rotating barbed pressure connector torch on a xyz axis stabilizer and positioning rail for the torch but enough of my book in my opinions 😂 thanks video gave my idea to fixing the 7000 dollar lathe diy for 200 to 350 depending on if you own a good 3d printer where did you get the file to print that specific design?

soo... how long will the machine last before the sieves needs to be replaced? and why not use peltier modules on the copper to condense the water?

Outstanding video thank you! Just the information I was looking for

I've just started working for a US vacuum manufacturer and one of the senior manufacturing engineers was geeking out showing me some vacuum pump system that took the vacuum all the way down to e-13 mBar but takes days of bakeout and running a turbomolecular pump at 150 L/s. Cool to see this video afterwards to better understand how difficult that is to accomplish. Also, it is only e-13 mBar on a good day! XD He said the acceptable range is up to e-11 mBar at the worst but even e-12 mBar was good.

Western Electric claimed they were going to jump back into the essentials tube building process back at the start of the Russian/Ukranian war. But they were all hot air. I have written them a few times over time to ask how that was coming and I get the same PR corporate drivel. They are as worthless. They had a chance to corner a market both for hi-fi enthusiasts and guitar amp users, and literally did nothing.

Is there a chance you can talk about your tattoos? They look super cool I’d love to hear more!

Mate this is why you need to use the deep web. Its just normal web but much larger. Google has removed too much.

Im happy to contribute to the wide spread availability of borosilicate glass tubing

I used a single large stepper motor and then used pillow blocks with a hexagon center I then connected them with a hexagonal shaft this was all placed behind the lathe with a belt from each chuck attached to the shaft.. I don't know if I'm explaining it well but it made it to where the tail Chuck can move left and right while staying in sync and using only one motor no 3D printer no nothing I built it with two wood lathes the only problem I had was my truck size I didn't have a big enough inner diameter but I made it at 16 and I had nothing but hand tools if I did it today I definitely do the truck different but I've not seen anybody connect both chucks the way I did so id figure I'd mention it

I really love that this is built on a typical hand cart! EDIT: I'd love to see if the atmosphere input would benefit from a heat pump drying pack as is found in a system like the GE ventless Washer/dryer combo.... EDIT 2: You've got me so hooked in with this vid that I keep thinking of things to say... For the sensor hookups that you've yet to use... I bet that data could be integrated as feedback into a controller that gives a more steady/efficient output!!! I'd LOVE to see a video about that!

How do you only have 5.2K subs? Such quality content that is a year old, yet I have only _just_ found you? That is unacceptable -- do better YT!

Very interesting project.Would it be possible to use this system via combustion to produce purified Co2 for MIG welding?

When I clicked on this video I wasnt sure what to expect. It sure wasnt Bad Ass Applied Technologies, but here we are and I must say, you do a great job explaining things.

Glad to see you :)

Perfectly cromulent indeed

What a wholesome build, and great quality of the project and everything. This channel deserves 10x or 100x the audience and I am so glad the algorithm sent me here!

Amazing video!

Can you collect the nitrogen off this too? Also, I don't see why the medical industry couldn't shrink this so people on oxygen tanks could wheel a small version of this around instead of tanks.

4:30 Well - halfway _logarithmically_, maybe. If the moon is 3e-10, you probably still have like ≥1000x more air in your vacuum than on the moon.
