Very good I appreciate your ingeniousnity. How many times you have to pump? May be hundred times or two hundred times. To empty the jar will 90% of air. It should be good exercise for the hand. Doing daily many times if you have lot of work. It is worth saving hundreds of dollars? May all be happy and at ease, free from dis-ease. 🙏🙏🙏

Glass lids from cookware work very well if the lid does break.

with a 12v vacum pump the final result will be the same?

Nice concept, I'm gonna keep going though since I am going for outer space levels of vacuum for what I am doing, which is a whole other field.

To note that your gauge does not show psi but mmHg or inHg

First and foremost is to wear safety glasses

What about adapting a large mason jar type container? Or one of those ‘Bale Wire Glass Jars’ ? Ya know like in heath food stores? I saw online they’re now using silicone rings. Sizing would be key. Just spitballing here. Sorry if I’m going off topic. One idea sparks another. Thanks for the info & inspiration!

I picked up a brake bleeder vacuum pump in a nice hard plastic storage case at my local Goodwill for like $6. I wasn't even sure what it was exactly, but I knew it was some sort of vacuum pump. I thought I might really need this some day and it looks like it isn't cheap. Had it for a year. Now I need to resin-pot some high voltage transformers and I need to vacuum pump them to get the air bubbles out so they don't arc and short out. I might use an old pressure cooker in place of the glass jar because it is designed for high pressure, has a seal, and I can attach the host to the built in release valve to pump out the air.

Awesome! Best & cheapest I've seen yet! Thank you for posting this! Question: Do you think a 5 gal plastic pickle bucket with a gama lid would work? Maybe hafta fill the voids between jars with stones (to keep the bucket from collapsing)? Has anyone tried that? Just wondering. This glass thing is cheaper, but the bucket would hold more. Kindv important when using manual brake bleeder like I do on my way too small PVC chamber.

Cool, Thanks

Ummm.... I clicked on this video thinking it was how to make a vacuum chamber for preserving dried foods! Ooops! LouiseAustralia 🦘

The first thing taught about instructional video creation is "Show Don't Tell" or "The More You Talk the Stupider You Look". Thus the incredible popularity in ASMR videos. Get a clue and use text graphics if you must communicate. Besides, your voice is very grating. Cheers! Ummm, Ahhhh, Errrr...

Don't know if I'll ever need a vacuum chamber but if I do I'll be following your instructions. Thanks for taking the time!

an old pressure cooker works well without much re-engineering also

Could a mason jar work?

sweet

If you're stabilising small pieces then a large coffee jar will suffice, plus it'll take less time to pump out the air, nice tutorial though.

Could I use something like a pickle jar instead of buying a new jar and sealing it with silicone?

crackhead engineering at its finest. amazing design thanks!.

Do you sell these and if so how much and about how long does it take to ship

Great design and its cordless! One thing I would change is the container. If it fails there will be shards of glass flying around. Just use a metal pot from a Goodwill store and switch the lid out for a thick piece of plexi-glass that you can find in a dumpster or buy if needed. I like to dumpster dive so I already have a few large pieces of 1" thick plexi-glass.

Yeah you know after a time ppl will get tired of drawinf a vacuum with the brake bleeder. And upgrade to a fridge compressor. Anerica is such a throw-away culture you probably will find a fridge on the side of the road.

USE MY BRAKE BLEEDER, DUH! THANKS!

also if you build this you can all ways upgrade from the manual pump and get a 50 120$ airbrush compressor

Genial! (means Genius in pt/fr)

You literally made one of those flour or food storage pots that have the hinged latches on the front! They make them out of metal, plastic, glass, etc and have silicone seals. All you would've had to do is drill a hole. Lol.

Awesome, I was about to splush on a complicated vacuum chamber for metal evaporation, but with this I can deposit some aluminium on my silicon wafers on a budget!

Danger!!!

a cheap vacuum food sealer can do the trick too. just get one with a hose adapter inside.

Fantastic stuff!

Very nice! 👍

Hahaha, a good one! :-D

I dare you to show a time lapse of you pumping that down to 29 inches with that hand pump. I'm guessing that 20 years from now I'll still be waiting for you to do it. 20 in is not is not enough vacuum to be useful. You won't pull any bubbles out of resin until you're down around 27 inches.

This makes me very nervous. I used to work on CRT televisions, that is a glass bottle with a vacuum in it. An implosion is NOT gentle. Pieces bounce off each other, some just fly past everything and continue outwards. The front of a CRT is very heavy, thick glass. However, the back is fairly thin as it is normally protected inside the case. If you break that glass, it can throw shards 20ft. I wasn't there for it, but I worked with a tech that had someone break a CRT in his shop. One of the pieces flew 20ft, cut through his pants like they weren't there, and embed itself in the leg of his bench. He was lucky, it just barely shaved some skin off his calf. It took a pair of pliers to pull the glass out of the bench.

I bought a HF paint pot on sale. You can't see in it, but just about everything you need to do for a vacuum chamber is already done. I also bought a returned vacuum pump, only thing wrong was it was missing the oil.

Great idea. I've tried 3d resin printing with clear resin, that, well, didn't turn out very clear. I heard that degassing the resin prior might get better results, but, really I don't do a lot of it. This might be my perfect solution.

I may not need one right now, but this is one to save to my DIY library list.

Silicone takes a while to dry. What a pain in the ... Spend the xtra n get some quick dry, paint section of your box hardware store. Awesome vid dude. You rock!!!!

you can make a neat hole by tapping the glass with tip of a tungsten throwing dart. Takes ages

Nice! Practical solution

AWESOME!

I loved this video. Maybe you could use a pressure cooker with external locking instead. The glass is better for seeing what's going on inside, but some pressure cookers have glass windows too.

Dangerous! No Safety-Net or Self-Adhesive Foil around the glass. What, if it implodes?

KICKASS!! 😁👍

By far? 3 years later, I'm able to afford a 80-buck VEVOR complete solution during Black Friday... and don't have to waste 23 minutes pumping... Your solution is still relevant for poor countries though.

Epic video!

You might want to put it into a plastic container. Glass containers do sometimes implode.

You really don't want to be around when that glass chamber fails. A vacuum implosion is very similar to an explosion and that much flying glass is not going to be fun. A much safer alternative is to use a stainless steel cook pot just like most of the commercial vacuum Chambers do. A semi-acceptable alternative is to buy some half inch hardware cloth and make a container around your vacuum chamber so that when it fails you don't get large shards of glass flying at you.

Whats the max vaccum

Nice job. Ok class time for an implosion test. To do this place it in a 5 gallon bucket with some water. Set the lid on the bucket and start pumping. And for added safety,,,,don't tell Mom what you did with the cookie jar.
