Using my new VEVOR vacuum chamber and pump for PROFESSIONAL doll casting!

This week I'm unboxing and setting up my new vacuum chamber and pump from VEVOR... and I know at first glance, that might seem bizarre for a doll-oriented channel, but I promise it's important!
I'll walk you through the unboxing and assembly and tell you my thoughts along the way, including why it's important for my doll-making ventures. I definitely think it's a necessity for anyone who wants to produce quality dolls, and I'll include why in the video, too.
You can find this particular vacuum chamber and pump set here:

It's a great size for large projects, which is mostly what I'll be doing.
If you're familiar with what goes into BJD making, you might know what this means... and if you don't, then you've got something interesting to look forward to across the next month, because this is my first major tool acquired for the purpose of setting up a professional-quality doll casting studio at home!
There's more to say about what led to that, but I'll share it another time... :)

Thank you so much for this video! My pump came without instructions, so this was incredibly useful!

[@sarahlongshore2605]

That really is a game changer!!! No more bubbles!!!

[@PrincessofKeys]

I knew it was to remove bubbles! Can't wait to see the dolls you make in the future with this though.

[@LomisPlayground]

Thank you! I'm really excited to share how things turn out. Just waiting for the rest of the supplies I need...

[@albertolozada4124]

-30 inHg will never be reached due to air leaks in the plastic plug of the other hose connection, the plastic plug must be replaced with a metal one.

[@MsSaudm]

This is a Chinese company but they do sell a lot of reasonably priced items on Amazon However the instructions are usually vague or in Chinese So you have taken the mystery out for us GREAT JOB & THANKS VERY MUCH

[@LomisPlayground]

Thank you! Yeah, the vacuum pump's instructions are fortunately pretty understandable. The company representative I spoke with was very good with English and was great at answering my questions, too. It really helped me feel more confident about what I was getting!

[@geeljireoomaar6140]

Yeah, i bought an item from amazon a few mobths ago. It was from china and i am sure the instructions were sourced from google translation

[@klischke]

I really appreciate this video! I was a little reticent to turn on my pump for my vacuum chamber because the instructions included are so brief but I followed what you did and everything worked really well with mine. Thank you for posting this!

[@danieladownie6087]

Wow this is some serious crafting! The stuff you make is gonna be incredible!

[@AnArmouredMouse]

That was a really helpful video. You may have saved my lid, kept from making a huge mess in my work area and inside the chamber itself. Thank you so much!

[@d.a.n.3086]

Excellent! I have viewed many of vacuum chamber “tutorials” you have done a great job!

[@DoesWhatItLikes]

Thank ya for a tutorial! I successfully ran a mold with (a little) less fear of the vacuum exploding in my face XD

[@minb1217]

It just shows you have to have to be a bit shameless and ask doesn’t it! Well done - a fantastic tool. Much better than a T-shirt press!

[@TheMinecraftguy65]

Thank you for an honest and detailed review on this chamber, I will be purchasing this chamber for another project ill be using it for. Because I have no interest in dolls. Thank you again for a great detailed video!

[@betty_davis]

This is so cool, I can't wait to see more of your projects 😊

[@metSander]

Thank you this was very useful. The provided factory instructions were very bad, I think they should this video instead. Got everything to work now 👍

[@emgee8483]

Thanks for uploading and sharing. 👍

[@davidg3858]

What a great video. Thank you

[@rawtoastcereal4312]

You can buy labeled vacuum pump oil at any automotive parts store. If your unsure ask the counter.

[@LomisPlayground]

I guess it depends! I checked three nearby and none of them had it. Two didn't even carry it, one said they were out of stock. Which is why I headed to Home Depot. :)

[@StudioKris10a]

Thank you so much to make this video it is VERY helpfull ❤

[@Joestacemazjojo]

Thank you as this went into the details I think I’ll need for epoxy resin, I’ve yet to catch a set up video on the poplar kit and as I’ve read instructions are not that helpful.

[@mrjustindraws4906]

Awesome!

[@grimnirnacht]

I would love to see a video on your compression pot if you have one. I tried to make one out of a paint pot but was unsuccessful for long term curing (wouldn't hold pressure for 12 hours). And the professional ready made ones are so expensive

[@LomisPlayground]

I'm planning to do that soon, don't worry! I hope to show my whole casting setup + materials in December.

[@renesalinas1029]

Vacuum chamber raises bubbles from resin or silicone, pressure pot makes bubbles microscopic I have both but I haven't set them up yet I'm gonna try to set up vacuum chamber first

[@LomisPlayground]

Yeah, in the strictest sense a vacuum chamber isn't necessary if you do things one at a time in a pressure pot... the biggest advantage of having a vacuum chamber is if you need to cure outside a pressure chamber. Since it's easiest to pour lots of molds at the same time, especially for large projects like what I typically do, it's super helpful to be able to degas the silicone, pour 10-12 molds in one go, and let it cure on my studio table. Huge time saver to mix and pour everything at once!

[@emal2170]

I'd like to try porcelain. I want to improve My Blender skills (or lack of) first. I've never tried silicone, but I do already have a 2 stage vac in the garage for AC. I've been doing everything with FDM so far. I do have a Elegoo saturn s in wrapping paper waiting for me to learn too.

[@nimo517]

*outside temperature, more than inside temperature, has effect on pulling a full vacuum or not* I couldn’t get mine up to (down to) -25hg and was frustrated with the purchase. Then when I went inside with the chamber, away from the cold, the guage showed a -32hgl after 20 minutes

[@MM-oc3sb]

What a great and heloful video, thank you! We are wondering about the misting that comes out of the filter... how much is normal? Also, ours did not have that guage sticker... Hubby is a Professional Mechanical Engineer and hasn't opened tops of oil-filled gauges through many years, so we are unsure of that need, perhaps just a plug for filling/replacing guage oil...? Thank you again for your wonderfully detailed set-up guide 💯😊

[@LomisPlayground]

I think the amount of misting will vary... Mine doesn't emit any at all, but I've heard from others that it can leave a small amount of oily film near the pump. I suspect mine will begin showing a bit of misting as the filter ages, but I guess we'll see what happens. I've also never had to open a gauge on anything else, this seemed to have been a unique need for this one. Possibly just the style of how this one is made? Who knows!

[@MM-oc3sb]

[@geeljireoomaar6140]

Thanks very much for this tutorial. Do you have any idea about the cost

[@alexandraalex5234]

👍👍👍

[@africancichlids3011]

Thanx

[@flowercast]

Another question if you don't mind.. I'm just wondering would the pressure pot heat the resin and also roughly how long does it take to remove bubbles. 1-2 hours? More? I'd be mixing roughly about 900 Mills at a time

[@LomisPlayground]

It does not produce heat, so there would be no thermal interference with anything you are degassing. The amount of time it takes to remove bubbles will vary greatly depending on the viscosity of what you're working with, though, so it's impossible for me to say - the manufacturer of whatever material you're using should have more information on this, though! For me, removing bubbles from my silicone--which was extremely dense and thick--took 2 or 3 minutes.

[@jimholowach457]

How long should you keep 500 ml in the chamber when using epoxy resin. I want to start making pyramids. Any tips would be greatly appreciated😊❤️

[@LomisPlayground]

Time needed will vary based on viscosity - it usually takes a few minutes, so resins with very short working times aren't good candidates for vacuum degassing. Just like with silicones, though, you'd want to have your epoxy mixed in a container large enough to allow it to expand to 3x its size, turn on the chamber, and let it pull and expand. As soon as it collapses back in on itself, it's fully degassed and can be used. It's normal for things to continue to bubble after degassing is complete, so just watch for that collapse to let you know it's done!

[@flowercast]

Hiya, thanks for the upload. I just ordered this hoping my moulds with resin will fit in. I ordered the five gallon with the vacume chamber but would have any idea what the inside dimensions are?

[@LomisPlayground]

The interior dimensions are 10 and 7/8ths inches wide, and 11 and 1/4 inches tall.

[@YevhenBulakh]

nice voice 😍

[@glennxi]

The gauge stays at zero.. did I get a defective one? 😢

[@suki4410]

Is enough oil in it? Are there any leaks in the hose?

[@renesalinas1029]

What is that rubber peak for? And what do we cut off just the tip?

[@LomisPlayground]

It's a seal on the gauge vent. It needs to be able to draw some air in to work properly. Too big of a hole would cause false readings. It should be stored upright after cutting because the gauge contains oil and could leak, which is why it's sealed for shipping.

[@renesalinas1029]

@@LomisPlayground omg thank you so much I didn't do that and my vacuum chamber wasn't vacuuming all the way like yours lol

[@sergeipro3642]

What is size of vacuum chamber on video?

[@LomisPlayground]

5 gallon :)

[@tmills4653]

Hey, how is this going 12 months on?

[@LomisPlayground]

No problems so far! Everything is still running, sealing, and pulling fine. It definitely has met all my needs for mold making and resin casting.

[@tmills4653]

@@LomisPlayground great thanks for the feedback 😀

[@christinaholk]

Is it loud?

[@LomisPlayground]

It's really not! I expected it to be super noisy like my air compressor is, but it isn't.

[@christopherlee1673]

I never saw a sticker or instructions to cut the rubber on top of the gauge so what am i missing by not doing that, would your gauge drain if you turn it upside down??

[@LomisPlayground]

It may vary some by the company that produces your vacuum chamber. Mine had a sticker on it that indicated the top needed to be cut, but other types of gauges may not require it. For mine, it did not give an accurate reading for how hard the vacuum was pulling until I cut it open as the sticker indicated. The worst that will happen if you don't cut it is it might not give an accurate reading for vacuum pressure. Everything else will still work just fine :) I have not had any issues with leakage from mine, the oil inside the gauge is very viscous so I guess it is too thick to escape the tiny inlet hole in the rubber!
