How to remove bubbles from resin castings with the vacuum chamber
Vložit
- čas přidán 6. 03. 2019
- Most people would recommend a pressure pot for degassing resin. But if you use a slow setting resin, the vacuum chamber can really work on achieving crystal clear castings.
Tools and materials I propose:
Vacuum chamber kit: amzn.to/2E4L5jd
Vacuum pump oil: amzn.to/2Ul0XE5

Once in a while you find a video demonstration that answers your question to perfection. This was one of those videos. Excellent 10/10
Thank you very much
Amazing video
For real! Dang other people talk to much about irrelevant stuff lol
Thank you!! 🫶
This was a great video! My chamber didn’t really come with very clear instructions and my model is very similar to yours. This video has aged very well 👌
Thank you
Thank you... A very clear, concise, demonstration as to why it’s a good idea to de-gas your resin.
Thank you
Wow when you added the light, mind blown! Was going to get a pressure pot also but I think this will do the trick with my clear cast 7050. Cheers my dude for the video!
I think if you can get away with a vacuum pot for your needs then it is best to stay there. You can always get better results with a pressure pot as you can do it after pouring your mold but there is also significant danger involved with pressure pots. Vacuum is not even close to as bad as things will implode rather than explode. It can still be dangerous of course but just not as bad.
This video doesn't really show it but you usually end up with bubbles on your pour into the mold when you use a vacuum pot. This really depends on the exact mold you use, some are easier than others to avoid bubbles.
This is a really great video man, straight to the point and informative. Helps a ton, thank you.
Thank you
I am about to invest in a vacuum chuck for my lathe. I also have some beautiful pieces of wood that need to be patched with resin. I had thought of buying a pressure pot , but thanks to your video I'll do it with a vacuum pot. Thanks.
Perfect, just ordered this exact machine.
Thanks.
I'm new to resin stuff, and this video answered literally every question I could have had about the process. Thank you for this
I am very glad to hear that. Thank you for watching and commenting. :)
That's an insane amount of bubbles created in the mixing process.
Great informative video, mate 👍
Thanks, actually they are many!
Fascinating! And dramatic is certainly the word. Amazing to see just how much air is dissolved in the resin - it produces so much foam. That's quite dramatic too. Thanks for this mate, most interesting.
Thanks Mark, it's actually pretty interesting to visualize the air trapped in there!
So happy I watched this before trying my pump! (of course I'll ready the instructions, but I'm a visual learning person). You've saved me some real messes! Pressure pots scare me ever since I was a kid and saw an accident with a kitchen pressure pot.
Nice to hear that!
This is wonderful!! I haven’t I put my chamber together yet. Good to know it takes a few vacuum sessions.
thanks for watching
I used to vacuum acrylic resin several years ago. I utilized a technique I haven't heard mentioned in any of these videos. When the resin was about to overflow, I would close all valves and trap the vacuum. The bubbles would slowly subside on their own. Then I would vacuum again, trap again, and repeat until I saw no more bubbles.
Totally agree!
Very nice and clear video. Thanks for the great work!
Great video, Dimitri! Enlightening, to say the least.
Thank you Nik
Great demonstration!! 😃 Thanks, Scrap Wood City!! 😃
Your accent is so wonderful. Accents are like music!

Excellent demonstration. Questions answered.
Nice to hear that, thanks!
Thank you so much for answering all my questions. Great video; straight to the point.
Nice to hear that! :)
This was the best vacuum chamber video I've seen so far. I was debating to get a preassur pot of a vacuum chamber. But this video made it clear to me that I can just use a vacuum chamber since I'll casting things using a slow cure resin. Thanks for sharing! 👍
Nice to hear that, thank you
@@ScrapwoodCity your welcome. You clarified my doubt because everyone else was saying its better to use a preasure pot to cast resin but you showed how by letting some air in every time the resin rises to bring it back down, will eventually get rid of all the air bubbles. So no need to have to use both machines.
Very clear and well presented demo. Thank you.
Thank you for watching and commenting.
This was incredibly helpful, thank you!!
Glad it was helpful!
Very nice explanation, great results man 👏
thanks man
Thank you for this video. I just bought a vacuum chamber, but it came with zero istructions. This showed me exactly what I wanted to know. Simple and clear explanation.
Nice to hear that
Thanks
You explained it to me to the way I wanted it.
nice to hear that
I've got this vacuum but wasn't sure how to use. Thanks for the tutorial. Now I'm going to give it a ago. Cheers.
Nice to hear that
Very nice experiment man! i love videos like this!
thank you
@@ScrapwoodCity you are welcome!
Thank you, very well explained ans straight to the point.
Hello sir, I would like to first say thank you for this detailed and informative “how to” and result review of you video. Secondly I want to ask you to please do a similar descriptive video on “how to” sand and polish the rough product and discuss the equipment you use. I am sure that all your followers and potential followers seeking this type of how to video.
Again thank you and hope you will consider my request. Your followers will thank you for it 👍🏽
Thank you. I have the polishing process video in mind. I think I am going to do it at some point!
Thank you for this video! I’m going to try this later today.
Nice!
Excellent video, very useful to me for degassing resin not using a pressure pot 👍👍👍
Nice to hear that

Χαίρομαι. :)
Thank you for the detailed video, I learned a few good new tips 🙏 Can I ask this, can you out for example a piece of resin jewelry wood for example in the mould with the resin poured, and then put that as is in the vacuum chamber ? Or is it only good to do resin on its own ? Many thanks 😊
Excellent. Thank you
Thank you for watching and commenting
Awesome video. This helped me figure out how to do this for the first time, thank you. Do you leave the oil cap on or off while the pump is running?
Thank you. To be honest I don't remember. I think it is on .
tengo ese equipo mismo de vacío. No le quitas el tapón azul para que salga el gas?
Thank you!!
This is exactly what I wanted! I just bought my vacuum and I was so nervous because I couldn't find basic info. I am testing this with a 1.5 inch cube so it isn't massive and shouldn't take too much I hope!
Awesome to hear that my video helped you
It's true.... 30+ mins resin is always a good choice.
Einfach nur toll ❤️
🧡
Thank you
Ωραίο εργαλείο και φοβερή επεξήγηση να σε καλά ωρέ!!!

Hi, do you add the hardner to the resin before putting it in the vacuum chamber
Thanks for sharing that
Thanks for watching
That was a really helpful video. I’m new to resin woodturning and was trying to work out which is the best process to use to remove bubbles - vacuum pot or pressure pot. This method seems to be perfect! You mention about using slow setting resins; the one I usually use sets in 24 hours - would this be too quick for it to work? Thanks for your help.
You need about an hour of working time in my opinion. Check the specs of your resin. :)
OK, thank you - will do
Does tap water boil at room temperature in your chamber? I am thinking your red dye was suspended in tap water, distilled water, or alcohol and that liquid boiled off as well as the other bubbles expanding to exit.
Hi, thanks for posting and sharing tips on how to degas resin!
How are you able to keep the pump going for that long? My instruction manual says that once the needle stops moving the pump needs to be shut off. I have a 2 QT BACOENG VACCUM CHAMBER AND PUMP. It takes less the 30 seconds for the needle to get to -29 and then stops moving and I have to shut it off (stays on less then 1 minute) and there are still so much bubbles in the container. I hope you can help me.
Actually I don't turn the pump off. I usually de-gass for about 5 minutes then I stop and then I repeat the process a couple of times more. Sometimes you may still see bubbles during the vacuum process. But in the final product they will not be visible!
@@ScrapwoodCity okay thank you!👍🙂
I have the same vaccum chamber liz, did not turning off the pump help?
I love your voice...!
Hi, I know this video is old, but will this work for gel candle wax? As they tend to have bubbles too
Now, would you do this while the resin is IN the mold or before you pour it?
What about vacuuming multiple times, then (as long as you don't mix it again) pouring the resin into something will it end up with bubbles again from pouring?
i saw it from another video and she vaccum it after pouring the resin in the mold too..
nice video !! one question : the percentage of shrinkage of the resin was the same on both cups ? or the one with vaccum had less shrinkage ?
To be honest I didn't notice
I've discovered that my resin casting literally deflates when I use this technique. Not sure if I'm going too fast or using a resin that sets too quickly or both but my results are catastrophic. I'm using five minute set resin. Please help!
Interesante máquina. Saludos
thank you
Many thanks for the video! How much does it roughly take to remove bubbles?
Depends on the quantity.vI usually am done in a bout 10 minutes
So many people need to understand how essential degassing is. And not just before the pour, but after. But, don't a lot of long-settimg resins build up more heat? And I'd still recommend pressurizing during the final setting. My experience is not from making beautiful art pieces, but making hardware that goes into outer space. It is nice to see these standards being applied to art as well. Beautiful example of proper degassing.
Also, I highly recommend opening the release valve and normalizing the pressure BEFORE turning off the vacuum pump, especially if you are using an oil-lubricated pump. Otherwise the vacuum chamber can pull contaminants and oil out of the pump and into the chamber.
Thank you for your comment. I will try out your suggestions. In my video all I did is sharing my personal experience knowing that it works for me and the kind of projects I do!
@@MattThompsonOnGoogle so basically release first then turn off the pump?
what kind of resin do you use?
Hi amazing! This work for polyurethane resin smooth on too? Thank u!
Np polyurethane is much faster. Yhe vacuum would not work
Hi! Thank u for reply back! So thankful.💝can you tell me how can I degassing the polyurethane? Even if I have to pay a tutorial. No problem. Thank u!
I fill the flowers with resin in the form of a round closed 8 cm. Does the vacuum chamber help to remove bubbles?
It should. It also helps the resin to fill difficult to reach or hollow areas
@@ScrapwoodCity thank U .what is better for this
vacuum chamber or pressure chamber?
You sound very Cuban. Amazing video
I am Greek. :)
What resin are you using?
How much does this increase the strength of the resin? Looks great too.
I don't know the answer to that.
Hi there. I'm new to this whole thing and while doing some research I learn there's one and two stage vacuum set ups. Which are you using?
Hello, mine is a one stage pump! I think this has to do with the capacity of your pump! More stages more empty space in your pot!
Thanks so much - this is really helpful!
@@KJ-Serene nice to hear that :)
Al hacer el proceso varias veces las burbujas en la superficie se liberan y la resina queda mas limpia
Hii. What is considered a slow setting resin ?
Can i put in this vacuum round mold with resin ? Not in cup like on video but already in mold
Thank you)
You definitely can
Can you place a silicon mould in a vacuum with resin? Would it give the same result? Thank you :)
Yes you definitely can. But the mold mustn't be filled all the way up. If it is, it will overflow at some point. So have that in mind when you make the mold.
where did you get that scale
When I use mine my resin gets so bubbly and high and out the cup and I still have bubbles. Advice ?
Let the pressure back in till they collapse and pull the vacuum again. Don that until you can keep a vacuum without excessive bubbles. If that's what you're doing, try a different resin

Would this be good for small concrete castings?
I haven't tried it. But I don't see why it wouldn't!
Does it have to be slow curing/
Can you cure it inside of the vaccum chamber or you need to takie it out for curing?
If you turn the vacuum pump off, I don't see why not. I often do it
Do you know what happens if you put wet concrete in a mould? Does it remove air pockets?
I haven't tried it but I guess it would work
I have used vaacum chamber on urethane rubber but it seems to struggle with getting all of the air out.
Don't know, haven't done that.
wow big difference...tyou
First :)
Nice video friend
thank you
can you tell me what brand of resin you are using?
Cheap ass brand for sure.
Do you think this would work with casting dice?
I guess so
I noticed you didn't put the oil cap back on for your vacuum pump.. is there a purpose for that?
No, sometimes it pops out!
@@ScrapwoodCity oh okay 👍I was just wondering if I was doing something wrong. Lol thanks for the quick reply!🙂
Nice explanation and video. When you say "slow setting resin", is there a reason for using one that takes so long? What brand? Thank you!
Thank you. The vacuum process needs about 20minutes, so a resin that starts to set in an hour or so won’t work.
@@ScrapwoodCity Pardon, I'm not understanding why that wouldn't work. If it starts to set in an hour and it takes 20 minutes to degas wouldn't you have 40 minutes to work with it?
Thank you for making this excellent video :)
Hey how can i use the vacuum to remove resin bubbles on a table? I’m new in this things
Are you putting the resin onto the table? If so take a heat gun or hair dryer to it and that should help.
The only way to use a vacuum chamber for table pours is to degas the resin after mixing and before pouring it onto the table.
I wish I would have watched this video BEFORE I tried de-gassing my epoxy resin for the first time…then I wouldn’t have tried to do it in one pass, with the resin bubbling up and overflowing, turning the inside of my chamber into a big sticky mess! 😢
