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.
yeah, but I just bought one of these jars, and the glass is pretty thick. Not "a baseball bat won't break it" thick, but i believe it will be fine for a max of 20lbs of force, which is the max recommended rating on the brake bleeder. Yes, the gauge does go higher. but I know better than to test Harbor Freight tools. also, I'm not sure about that second-hand account, unless the old console TVs are different somehow to a CRT monitor. I once broke thru the front screen of an old console TV. it took several swings with a bat to make a small chip. when that didn't work, I hurled a 20 lb barbell at it. that punched thru. there was definitely glass that flew past me, but not with the force that would embed a shard into wood. I certainly didn't have any cuts.
@Simon Ahmed you want a cookie for that? Good for you??? P.S, did you really just go on another youtube account and reply to yourself? What a loser. lmao
He could make it cheaper by using a clear plastic air tight box, saving time & money or something like those cylindrical glass jars with those metal lids (idk what its called)
This is a really solid, no-nonsense video, thank you for posting it. I am going to share it with a bunch of people who make dice from epoxy, as they are currently using/thinking of using those other more complex/expensive methods from other videos you talked about, as was I.
I used a kilner jar got fantastic rubber seals and its clip held down,drilled a hole with a tile drill placed in a sink of cold water,glued the adapter in the hole and its great. thanks for the video a great help,a word of warning dont try and take the lid off before getting air back in!!
This is a very interesting idea! I have a couple concerns/comments/suggestions: 1) Safety. For at least the first few tests, put this in a large cardboard or plastic box, in case it implodes. Those jars are not designed to take these forces, and I'd want to check before trusting them. 2) Speed. Definitely factor in the pot life of your epoxy, it looks like it could take quite a while to get a vacuum in a jar this size! Some mixes have additives or different ratios to prolong the pot life. 3) For a simplified/variable system, perhaps a thick chunk of Nylon (I'm sure you could get 1" thick Nylon or even polycarbonate sheet for not too much money) with the silicone baking sheet stuck to it as a base plate. The vacuum nozzle can run under the sheet, and up through a hole in the centre of the base plate. Now you can put any size of jar over the top of the nozzle - small jars for small amounts of epoxy, larger jars for larger amounts or even filled moulds that you want to degass once poured - using the same base plate. It also means you are drilling a hole in plastic and not glass.
@@leojones1964 If what you want is a very safe vacuum chamber, then I'd just buy one - they aren't that terribly expensive. I can see ones from reputable resellers for under £100 here in the UK. Those come with a see-through lid, all the fittings and gauges... for under £130 you can get one with a vacuum pump as well. A good quality pressure cooker pot can cost that much (though they can be much cheaper). You could use a metal pot, but that does make it much harder/messier to use. Being able to see that the material has stopped bubbling, or that it's about to overflow the container and make a horrible mess - these are important, too. If you are degassing epoxy unsighted, make sure there is plenty room for the bubbles to rise into and use a secondary container to catch any overflow (a sensible thing to do even if you can see). Also, it may be worth tweaking your accelerator or catalyst to give yourself a bit more working time, to make sure the epoxy hasn't set while you're degassing, and de-gas for a bit longer to make sure you've got all the bubbles out. An interesting side-note about bubbles, though: Someone I know did a study on 2-part polyurethane mixes, and those that were vigorously stirred to include bubbles and not degassed were slightly tougher and tear-resistant, though overall weaker. The bubbles blunt the start of tear formation. It's a minor difference, but a measurable one. Thought I'd throw that in here!
Some additional safety idea. Often I have seen glass vacuum desiccaters wrapped in tape to mitigate the danger of an implosion. I prefer a plastic bell shaped vacuum chamber.
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.
@@jude7321 I’m pretty sure it would just expand and pop, I was thinking along the lines of a block of something without air in it. Even a container of water.
@@bluemoon8268 Good idea, with the advantage that marbles ‘flow’ to fill your empty container form so you could even immerse your casting between them.
Glass is such a reliable material, especially after the drilling. What could possibly go wrong? Its not like somebody's going to get hurt by anything sharp flying. Watch some videos of vacuum chambers failing. Its hilarious to see how startled people are. Not many videos of glass ones breaking. Those guys usually don't make it.
Stainless steel cooking pots are a better alternative provided the walls are thick enough. People are using it successfully to put aluminum on their telescope mirrors. Glass is really dangerous.
Amazon sells a 1.5 quart vacuum pot with a gauge and fittings for $35. Pick up a hand pump for $20. Done. A 1 gallon pot is $65. Still worth it considering it’s plug and play.
@Deanna's Creative Mess you're welcome. It may not be what you're looking for. Pressure is better at removing bubbles than a vacuum. I watched another video where I guy tested the 2 side by side with resin and the one under vacuum just expanded and over flowed the container it was in. I'm still not sure what I'm going to do. Good luck
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 video for a effective vacuum chamber for not a lot of money. One correction in one scene you have a text overlay that says the vacuum is 20 psi, that is not correct. A perfect vacuum is roughly 15 psi, the correct nomenclature is that the vacuum is 20 inches of HG (mercury). That is what your gauge is calibrated at.
This really looks amazing. The whole setup is cheaper than what one of the pumps alone could be bought for and it's so simple! I'll probably use a steel cookpot instead of a glass jar for mine, just a bit nervous keeping pressurized glass nearby, but I'll definitely have to give this a try when I start making dice and figures for me and my friends!
It's holding a vacuum not positive pressure, which makes me think it would be a gentle implosion if the glass broke, not a violent explosion throwing shards. But I have no experience, so who knows.
@@MrModTwelveFoot No, it would NOT be gentle! I used to work on CRT televisions, that is a glass bottle with a vacuum in it. The front of a CRT is very heavy, thick glass.

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.
Depending on the glass jar used, there's a risk of implosion, especially if the jar wall is thin, and is knocked with a sharp metal tool under pressure. To mitigate the risk of flying glass shards if the jar implodes, a really simple solution is to wrap the jar with clear packing tape. The tape will catch the glass shards in that case.
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 took a cheap hydraulic pump and fabricated fittings to brake lines to put brake cleaning fluid through a clogged brake line under a little pressure. I wore eye protection, and it worked.
That's awesome! I've been lookikng at a bench top vacuum chamber that works well, but cost about $150. I can't afford that. But I can afford this! So easy. I already have many of the supplies, so the only thing I'd have to purchase is the pump. Thanks for sharing!!
Great idea. If I make it, I'll be doing this upside down. The base would be a cookie sheet with the non stick on it. Then if still a hike in the jar, and that would be placed on top of whatever gets vacuumed. Great project.
to save even more money...you know those fabric type garden hoses....that expand when you turn on the water? They never last more than one season. When they eventually blow out, remove the fabric cover, and inside you'll find some very soft and flexible tubing that makes excellent gasket material for a project like this. So instead of using the baking mat and caulking, slit the tubing and apply it to the lip of the jar, maybe glue one length flat to the lid?
Hello Blake, Thank you for posting this video I know it will be a great help. I will keep you posted as to how my Vacuum Chamber works out. Keep up the great videos.
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!
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. 🙏🙏🙏
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.
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!
Thank you for posting this I have been trying to figure out how to do this for such a long time it took seeing one on Johns videos from Growing your greens to know exactly what I was looking for. Thank you thank you thank you I can’t wait to try this. Cheers.
Hi Blake great video, great idea and easy to follow - I will build mine coming weekend. Since I am even to clumsy to drill a hole into glas I guess I go for one of the extra solid vacuum food boxes (Hard Plastic!). Building time should be reduced to 5 minutes max. Remove the rubber valve which sits in the top of the box and hotglue the adapter of the pump right into it. Attach hose and you ought to be good to go. I use pu resin as a casting resin. I don´t want to degass the resin but suck out the airpockets out of he mold. See if that is going to work. Might be some sort of compromise ... keep up with your good work, cheers
That is a good idea. Instead of using hot glue I would use silicone. Hot glue can leave very small air gaps which you may not see. If you spread the silicone around all surfaces you should have a better seal.
Thanks a lot! You should do a video showing it working with epoxy! And a word of advice: Alternate between hands. Or you'll end up with a forearm bigger than the other in some months. Haha
it doesn't work for epoxy and resin.. Resin = pressure pot Silicone = Vacume. Go check some videos.. its a absolute mess trying to vacuum resin. I ended up making the harbor freight pressure pot for 80$ and added a harbor freight 1.5gal 125psi compressor for 70$
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!!!!
only very small molds.. degassing will make a mess and your resin will start setting before you degass it all unless you got like a 2h pot time.. I built this thing.. it isn't useful unfortunately
This is an outstanding build! Maybe use Proto Putty from the King of Random instead of a silpad and acrylic jar from a big box store. (Maybe Michaels) but, truly a real find on the internet!
Easiest and cheapest way to make a perfect seal in the lid and the jar: get a mirror larger than the lid/jar diameter. Get a piece of that plastic food wrapping like Cling or Saran wrap. Spray some water in the mirror, spread a piece of wrap on it and use something like a credit card to squeegee any bubbles out. That plastic must be perfectly spread, like if you were putting tints in your car's windshield. Put a thin layer of silicon in the lid, then press the lid on top of the wrap. The silicone will NOT stick to the wrap, and once cured, that silicone ring will be super flat. Repeat with the jar. The advantage with this is that now it doesn't matter the position of the lid because the seal is supposed to be perfectly flat all around. When you put those two silicon seals together they will seal like crazy.
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 solution to a quite expensive tool. I'm wondering if i should probably start with an old steel pressure cooker similar to the ones my mother used to cook with in the 80s and i think the lid seals tight if i remember correctly. The glass under pressure makes me nervous 😬 Well done though. Great video, direct, to the point and no b.s 👍🏻
Interesting concept. In theory, if you can find a high quality glass container with very flat surfaces, the silicone mat by itself might be enough to form a seal.
I really like this build. DIY projects can sometimes be a complicated mess that takes way to many stops just to get what you need but this is simple and straightforward. Often times things get so messy that I hit a point where i think "I'm an idiot" (which is tyue sometimes). This looks clean and simple.
thanks. I knew 2 things: I already had a Harbor Freight brake bleeder, and I wasn't about to pay $50-120 for the *cheapest* version of the resin vacuum chambers. it would have taken me a while to come around to considering a glass cookie jar ;-)
Use proto putty around the jar top. Works great. Mix 100% silicone caulk with corn starch and food coloring of your choice. Knead it into a putty and after about 2 minutes, you have another 5 minutes or so of working time before the putty solidifies. Pile it around lip of the jar and press your plexiglass down on it to make your seal. Let it cure, and you have the perfect gasket. There's no need to drill through the jar at all.
@@blakemcfarland6418 look up " making silicone mold with corn starch and silicone" to get ratios....I have seen it done to make your own silicone molds for resin projects
Great info! I was all set to buy a $200 pot when I found this, I already have everything except the brake bleeder so I know what my next project is. Thanks!
So much awesome! If perchance, I get my hands on a small motor, would it be easy as changing out the tube? Or not advisable due to the pressure and the glass?
A trick I use for goopin around tubes; stick a q-tip/toothpicks down the hole before applying whatever adhesive/lubricant, before set- remove and have a pristine opening! 😸👍
This is an absolute game-changer. As a hobbiest, I had no interest in dropping $250 on a tool I was only planning on using a handful of times. I can definitely justify this though. Thank you SO much!
Thank you, this will help me save sooooooo much time and frustration in the future. It also doubles as a dust free chamber. Super straightforward and adaptable to other designs.
What an awesome video, thanks so much for making it. I have been wanting a vacuum chamber for ages but I can't afford to buy one. I already have everything I need and my jar already has a seal on it but I will be doing what you did to make sure it seals properly, again thanks
man thankyou, i'm so glad I watched this, i now know how to build this cheaper but i'm going to see if I can make one cheaper lol just to see I think I can make it for around $30.00
I have read concerns about this so here is my2 cents. why not go to thrift store and find a pot with a lid that is clear and with a pressure hole? I have a lid like this and I will make it like taught and will see what happens.
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.
This is freaking awesome. Just spent a small fortune an a big ,noisy, smoke blowing monstrosity of a vacuum chamber. It rattles and hisses at me like it wants to blow up. Im rather terrified of using it for my little resin moulds. I will make one of these this weekend and let you know how it works
Dude legit I just bought one of those pumps thinking the same thing! I like the glass idea I’m using it for liquid plastisol for making fishing lures. I was going to use a mason jar with a locking lid so I don’t have to make the gasket but I like the volume of your container...
Thanks. Yeah I wish I could find a mason jar with locking lid large enough... I wanted to go as big as I possibly could so I went with this big jar. Using a jar with a lid would make this super easy and probably super air tight right out of the package.
BM Sculptures yea I’m going to use this same jar from Walmart I’m going to try and make something today after work II got some ideas on making a cheap electric one. I think I could use my AC vaccume attachment and a cheap air pump to remove the air quicker. I’m going to be doing about 24oz at a time so I need the volume

This is brilliant. Exactly what I was looking for. Good enough for a hobbyist without requiring mega expensive parts. Kudos mate!
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!
You might want to drill the glass first. If it breaks you didn’t waste time making the silicone o ring detail. Amazing idea though.

When they eventually blow out, remove the fabric cover, and inside you'll find some very soft and flexible tubing that makes excellent gasket material for a project like this. So instead of using the baking mat and caulking, slit the tubing and apply it to the lip of the jar, maybe glue one length flat to the lid?
Hello Blake, Thank you for posting this video I know it will be a great help. I will keep you posted as to how my Vacuum Chamber works out. Keep up the great videos.
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!
This is terrific! I've been wanting a vacuum chamber so I could stabilize some burl I have before turning. This is fantastic! Thank you so much.
OMG you are my hero!!!I've been needing a vacuum chamber and this is perfect.
haha awesome Glad I could help!
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.
🙏🙏🙏
I watched the video and step by step built the same one with the same tools except I used a smaller chamber and it works great
Searched around for diy vacuum chambers. Found one. Thank you.
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.
THANK YOU!! Im making one out of a mason jar. Was just looking to see if someone else did it and it worked or not😂😂
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!
Hi Blake. I just caught your video now. Did you do a follow-up video? I'm curious how your molds came out and if you still use it. Thanks
Well done mate I like easy peasy methods. Never seen that type vacuum pump,will look out for.
After failed dice attempts in cap molds cause of bubbles I cannot wait to try this thank u!
You can buy one on Amazon right now for the same price
It will fail, u need pressure not vacuum.
That's a really simple but really smart idea
I've been working with perpetual motion and this will greatly help. Thank you.
No it won't there's no such thing
Thank you for posting this I have been trying to figure out how to do this for such a long time it took seeing one on Johns videos from Growing your greens to know exactly what I was looking for. Thank you thank you thank you I can’t wait to try this. Cheers.
Hi Blake great video, great idea and easy to follow - I will build mine coming weekend. Since I am even to clumsy to drill a hole into glas I guess I go for one of the extra solid vacuum food boxes (Hard Plastic!). Building time should be reduced to 5 minutes max. Remove the rubber valve which sits in the top of the box and hotglue the adapter of the pump right into it. Attach hose and you ought to be good to go. I use pu resin as a casting resin. I don´t want to degass the resin but suck out the airpockets out of he mold. See if that is going to work. Might be some sort of compromise ... keep up with your good work, cheers
That is a good idea. Instead of using hot glue I would use silicone. Hot glue can leave very small air gaps which you may not see. If you spread the silicone around all surfaces you should have a better seal.
This is awsome and btw making protoputty with the silicone can cut your price down by making the seal that way super simple too!
Thanks a lot! You should do a video showing it working with epoxy!
And a word of advice: Alternate between hands. Or you'll end up with a forearm bigger than the other in some months. Haha
it doesn't work for epoxy and resin..
Resin = pressure pot
Silicone = Vacume.
Go check some videos.. its a absolute mess trying to vacuum resin.
I ended up making the harbor freight pressure pot for 80$ and added a harbor freight 1.5gal 125psi compressor for 70$
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!!!!
Great video! I'll be knocking one up over weekend for sure. Cheers for the idea mate.
Thank you! Good luck!
owo
I was thinking about this close to exact design while at Harbor freight yesterday!!!!
Thank you for this. I can now do all the resin casting I have been longing to do.
only very small molds.. degassing will make a mess and your resin will start setting before you degass it all unless you got like a 2h pot time.. I built this thing.. it isn't useful unfortunately
@@synapticdragon2157 well, you said it yourself: you can switch to different resin to make it work
Nice, easy and good presentation. Just perfekt for me now 😊
This is an outstanding build! Maybe use Proto Putty from the King of Random instead of a silpad and acrylic jar from a big box store. (Maybe Michaels) but, truly a real find on the internet!
Easiest and cheapest way to make a perfect seal in the lid and the jar: get a mirror larger than the lid/jar diameter. Get a piece of that plastic food wrapping like Cling or Saran wrap. Spray some water in the mirror, spread a piece of wrap on it and use something like a credit card to squeegee any bubbles out. That plastic must be perfectly spread, like if you were putting tints in your car's windshield. Put a thin layer of silicon in the lid, then press the lid on top of the wrap. The silicone will NOT stick to the wrap, and once cured, that silicone ring will be super flat. Repeat with the jar. The advantage with this is that now it doesn't matter the position of the lid because the seal is supposed to be perfectly flat all around. When you put those two silicon seals together they will seal like crazy.
اشكرك على جهودك ولكن هل تستطيع تحويل الماء إلى ثلج باقل تكاليف ومعدات بسيطه
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.
Or, maybe wouldn't hafta buy a gama lid? Use your method w/the silicone stuff instead? I get pickle buckets free from Burger King and Chic Filet
Mini vac hand pumps are great 👍
What about those jars with the gasket and flip clip? Wouldn't that be even MORE cost effective?
Was wondering the same thing.
Cool solution to a quite expensive tool. I'm wondering if i should probably start with an old steel pressure cooker similar to the ones my mother used to cook with in the 80s and i think the lid seals tight if i remember correctly. The glass under pressure makes me nervous 😬 Well done though. Great video, direct, to the point and no b.s 👍🏻
Great video. Is there a way seal the jar after vaccum?
Well my bong making game just went up.
Perfect way for a hobbies to start out… thanks
Interesting concept. In theory, if you can find a high quality glass container with very flat surfaces, the silicone mat by itself might be enough to form a seal.
Hot glue a ring down around where you wanna drill then fill the ring with water😎
I really like this build. DIY projects can sometimes be a complicated mess that takes way to many stops just to get what you need but this is simple and straightforward. Often times things get so messy that I hit a point where i think "I'm an idiot" (which is tyue sometimes). This looks clean and simple.
Could you dismantle the pump handle & attach a cam wheel to the vacuum piston & attach the cam wheel to the drill to make it much quicker...???
thanks. I knew 2 things: I already had a Harbor Freight brake bleeder, and I wasn't about to pay $50-120 for the *cheapest* version of the resin vacuum chambers. it would have taken me a while to come around to considering a glass cookie jar ;-)
What about using it for canning dry food? Using the canning jars and lids? Could sturdy plastic food containers be used for vacuum chamber?
I’m assuming this couod be used for sealing mason jars for food preservation as well?
Use proto putty around the jar top. Works great. Mix 100% silicone caulk with corn starch and food coloring of your choice. Knead it into a putty and after about 2 minutes, you have another 5 minutes or so of working time before the putty solidifies. Pile it around lip of the jar and press your plexiglass down on it to make your seal. Let it cure, and you have the perfect gasket. There's no need to drill through the jar at all.
interesting... Silicone and corn starch make the putty? What ratio would you recommend?
@@blakemcfarland6418 look up " making silicone mold with corn starch and silicone" to get ratios....I have seen it done to make your own silicone molds for resin projects
A guy at a pro store I talked to told me to make sure to add a filter to catch moisture as I let the air back in.
Very good Idea , thanks for posting this , I’m in the process of making me one
Great info! I was all set to buy a $200 pot when I found this, I already have everything except the brake bleeder so I know what my next project is. Thanks!
having tried this.. What do you need vacum for?
This wont work for resin.. I tried it already.. resin will set before you degass it enough
Did you ever get past 25 inhg? I think im still going to need to get a vacuum pump for silicone or acrylic
So much awesome! If perchance, I get my hands on a small motor, would it be easy as changing out the tube? Or not advisable due to the pressure and the glass?
Glass lids from cookware work very well if the lid does break.
This glass container can be purchased with a vent on top of lid for vac applications.
A trick I use for goopin around tubes; stick a q-tip/toothpicks down the hole before applying whatever adhesive/lubricant, before set- remove and have a pristine opening! 😸👍
This is an absolute game-changer. As a hobbiest, I had no interest in dropping $250 on a tool I was only planning on using a handful of times. I can definitely justify this though. Thank you SO much!
Thank you, this will help me save sooooooo much time and frustration in the future. It also doubles as a dust free chamber. Super straightforward and adaptable to other designs.
How Super.......
What an awesome video, thanks so much for making it. I have been wanting a vacuum chamber for ages but I can't afford to buy one. I already have everything I need and my jar already has a seal on it but I will be doing what you did to make sure it seals properly, again thanks
man thankyou, i'm so glad I watched this, i now know how to build this cheaper but i'm going to see if I can make one cheaper lol just to see I think I can make it for around $30.00
I do not know if that was a typo or an honest mistake but that pressure gauge is in inHg. -20 inHg is ~ -10 PSI. And it maxes out at ~ -15 PSI.
Was thinking exactly the same thing. Wondering if the hand pump could get up to 29 inhg / ~15 psi
Great
Can you please make a follow-up comparison video of resin cast with and without vaccum, please?
Thanks. I agree many options but expensive or tedious to put together
Fantastic idea!! But is it good for wood stabilisation?
Congrats 👏👏
Awesome breakdown big dog !! Super helpful n can’t wait to fab one of my own out
I have read concerns about this so here is my2 cents. why not go to thrift store and find a pot with a lid that is clear and with a pressure hole? I have a lid like this and I will make it like taught and will see what happens.
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.
Tip for fingering wet silicone, wet a piece of tissue paper/kitchen paper towel (silicon wont stick to it) use that to press it down
OMG, what a great tutorial! This is gonna be my next project! Thanks!
with the silicone mat, as the weather stripping really necessary to make a seal?
This is freaking awesome. Just spent a small fortune an a big ,noisy, smoke blowing monstrosity of a vacuum chamber. It rattles and hisses at me like it wants to blow up. Im rather terrified of using it for my little resin moulds. I will make one of these this weekend and let you know how it works
Tho im thinking instead of a big ol glass jar im going to use thick plastic air tight container like the ones you use for soup and liquids
I think that is a great idea... Then you don't need to worry about any kind of sealing of the lid. I wish I would have done that. Hope it goes well!
Could I use something like a pickle jar instead of buying a new jar and sealing it with silicone?
Great video , to get a cleaner cut you could use a protractor with a razor to cut your silicone mat .
Dude legit I just bought one of those pumps thinking the same thing! I like the glass idea I’m using it for liquid plastisol for making fishing lures. I was going to use a mason jar with a locking lid so I don’t have to make the gasket but I like the volume of your container...
Thanks. Yeah I wish I could find a mason jar with locking lid large enough... I wanted to go as big as I possibly could so I went with this big jar. Using a jar with a lid would make this super easy and probably super air tight right out of the package.
BM Sculptures yea I’m going to use this same jar from Walmart I’m going to try and make something today after work II got some ideas on making a cheap electric one. I think I could use my AC vaccume attachment and a cheap air pump to remove the air quicker. I’m going to be doing about 24oz at a time so I need the volume
BM Sculptures Thanks for the video! I’m going to try using a large pickle jar!
