The subtitles marked English are in Japanese. It's fine, of course, if there are no English subtitles, we aren't entitled to an English translation. Could you please correct the labels.
sorry, but i checked, and the subtitles are activated in english in youtube, but still not appearing. it's a real shame because your videos are very interesting. HI
This might be the best solution to a low cost vacuum pump I've ever seen - it's a shame you chose a clickbait title, because nobody looking for a vacuum pump solution is going to find this.
Instead of using return valve on the lid, put there a tire valve from old tire, upside down. You can create more valve lids to use on your stuf and it will be smaller than the return valve antene on the lid.
This good, the only thing is... i'd only do this with quality jar glass. Like take a jar from a specific brand and break them to figure out how thick the walls are. Because if the quality of the glass is poor, and the walls are uneven and thin. This could make it shatter. I've had jars pop from the vacuum of canning over the years, this is more. So one should exercise caution.
Thank you friend, I watched this video yesterday and made it this morning and it worked well. But I used push fittings since I had check valve, tee and screw in parts. I might motorise it with a slow motor. Will be really good for vacuum distillation. And you are right, saved me 40 bucks
Just yesterday I was thinking about a setup like this for storing rice long term. Surprised to see this in my recommendations today. Great job on passing the leak down test!
I also used this vacuum cleaner with a one-way valve to vacuum the sheets to save space in the closet. Just use double-sided tape to glue the valve to the zip bag very simply and effectively.
@@HyperactiveNeuron somewhat ironically I specified partial vacuum because I anytime you only say "vacuum" people come after you going well actually. Taking about perfect vacuums despite them never being mentioned. A partial vacuum doesn't have a defined valued, a physicist would likely consider anything that isn't a perfect vacuum a partial vacuum. No such thing as pretty much a total vacuum, that's the difference between getting the desired result, nothing happening or your turbomolecular pump blowing up.
@@oliverer3I read somewhere that 30" is basically the practical max at sea level. That said, the 27 he showed in this vid seems to be pretty good for such a cheap and easy DIY for small projects {shrugs}
Excelente proyecto muy bien desarrollado y mejor ejecutado maestro, envasado al vacío, se conserva mejor, gracias por compartir tanta información y conocimientos, un saludo cordial y por supuesto un merecido like desde Narón (Galicia)👍🤓😜
Friend, I really like your careful and well-planned work style. The idea of the video is very good, perhaps the cheapest vacuum pump on the planet, but I think that, seeing the comments, many people don't even understand why you vacuumed the food. I believe your videos would be more complete if you put some comments on the screen (actually written), with information relevant to why you are doing certain things, for those who didn't understand just by watching the video. Please continue your great work, I have learned a lot watching your videos!
тут бы про применение в технике рассказать. Например- можно вакуум использовать для пропитки пористых материалов лаком. Или использовать для откачивания пузырьков воздуха из эпоксидки итд.
@@andreyn1719 для дегазации эпоксидки и проч. это, конечно, тоже подойдёт, но для очень небольших деталей. Да и вакуум нужного разрежения особо пластиковым шприцом не сделать. Всё-таки если серьёзно литьём заниматься, наверно, нужно и чуть более серьёзное решение. А вот бытовое применение, показанное в ролике, как раз очень практичное, особенно для кофе. Кофе в открытой пачке окисляется за неделю-полторы, теряя вкус и аромат. Про пропитку пористых материалов -- интересная идея. Но ведь их будет распирать? Если несложно, поясните суть технологии.
Hello, do you think it would be possible to use this vacuum pump to remove bubbles from the resin if the container is large enough to hold the one containing the resin?
I have been thinking of building something like this to degas resin/epoxy/silicone. But building upside down, so i have an easier time placing and removing the cup, adding some sort of grill base as well. So with a weighted lid base and screwing the jar on top. I will consider your approach and your suggested parts (valves etc). I was thinking of making do with bicycle tyre valves. But in a pinch i can just use a suitable syringe and nothing else to degas mixed liquids like this. Simply load material in and hold the syringe nose shut while pulling back the plunger.
I made something similar to degas silicone/resin back when I used to build scale models. I used a handheld vacuum pump used to bleed vehicle brakes. Mytivac is the name brand, but there are a lot of cheaper knockoff brands that work just as well (certainly not as cheap as a syringe, though).
Beste vriend.Doe zo verder en op den duur worden mensen wijzer en wijzer en loopt de staat steeds verder en verder veel geld mis.Met hoe meer we zijn met hoe meer we weten.Groeten uit belgië.
Domo arigato, sensei. Do you think maybe with a little bit bigger syringe one could make this work for vacuum degassing of epoxy resin and silicone for casting ?
creating a vacuum is rather easy with a hot aqueous solution. Just put it in a jar, seal it and let cool. That is how conserves or canning are made. And you don't need a liquid is you can substitute the air in the jar by over heated steam. In the food industry it is called a steam tunnel. You could experiment putting your resins in a container within a jar filled with boiling water. It might work.
I'd enjoy it in a how to make crystal clear ice video. I got some ice cube molds and never found a convenient way to degas water for those beautiful crystal clear cubes or mini "Death Star" ice...
Excellent tool. I sent the link to a friend who makes silicone molds of 3D printed parts. Wide mouth mason jars would be perfect vacuum chambers for making molds.
Would it be cheaper/more efficient to epoxy a bit of tube in the lid? Once vacuumed, pinch the tube and put a bung in it. Then you don't need a one-way valve for each lid. Very cool idea and surprising the vac you pulled with just a syringe. Thanks!
"Would it be cheaper/more efficient..." No, your idea wouldn't work. He's using one-way check valves. The triangles on the check valves show which way the air can flow; air can't flow in the opposite direction (rewatch the video, the direction of the triangles is important to make this work). Air can only be drawn out of the glass jar on the syringe upstroke, and air can only be discharged to atmosphere on the syringe down stroke. The repeated up and down strokes of the syringe evacuates the air from the jar and ejects it to atmosphere, creating a vacuum in the jar.
@@ianshand6094 You've misunderstood I think. Still use both one way check valves (One drawing out of the jar, the other ejecting air out of the syringe.) But instead of leaving the jar check valve on the jar (and every jar) you leave it on the syringe. It just gets plugged into the stub of tubed epoxied into the lid. Hook up the check valve/syringe unit to the jar tube stub. Draw the vacuum. Pinch the jar tube stub closed. Disconnect check valve/syringe unit. Plug jar tube to retain vacuum. See? Instead of leaving check valves on the jars, acting as 'plugs' in the lid hole, you're just using a plug in the jar tube so the same check valve can be used each time. (Not that these check valves are particularly expensive. But a tube and plug/bung is cheaper and likely easier to store than a comparatively large plastic cylinder protruding out the top.)
Grandioso. Peccato che i prezzi sugli accessori necessari su Amazon da noi in Italia siano carissimi rispetto al Giappone. Solo tubo 5 metri e raccordi 1585,7 yen pari a 16,48 euro.
@@Sparky_D So only you can speak. Did I say Taiwan is the same as China. Why don't you check the link for the "non return Valve" shown in the description. Maybe it would help you.
I have a phobia of high pressure stuff (on the back of my head I’m always thinking is going to explode or implode). But at the same time I love crafts and my compressor & airbrush are my favorite tools. With those things in mind I must ask, how safe is this? Cuz I want to make one and test with resin and silicone. 😅 PS: I feel kind of silly for asking like this.
I was about to begin trying out making artisan keycaps and working with molds and resin and this is a great and cheap alternative for a pressure pot. Sure it won't be as extreme (or rather will take some elbow grease to do it) but this is great. Literally bought everything just 2 days after your video and already got it working, though haven't tried it with silicone/resin yet. 素晴らしいヒントをありがとう!
Honestly, there is already something for DIY vacuum packing ... it's an Italian patent (tre spade vacuum takaje )instead of the aquarium valve with epox make a hole in the center of the original cover put a kind of cap with silicone seals and that's it
