I don't think this design will work. The lid is not strong enough. If you have a jar with a thicker lid and two-sided or even three-sided clamps, the structure can withstand the excess pressure inside.
Great question! And a great idea! A mason jar can withstand a full vacuum of 32 in Hg. However, the lid and ring assembly will typically fail at less than 15 in Hg. If you can use something harder as a lid, why not!
It took three runs to get rid of bubbles. The warmer the resin, the faster the bubbles will release. To get the best result you can place cans with resin in hot water for 20 minutes before the procedure.
Don't think it will be powerful enough to reach a vacuum of 20 inHg. In the video that I found here on TH-cam, the maximum of 12 v pump was only 15 inHg. Although if you have such a pump, try it. It might be enough for a small amount of resin.
follow your instruction I made my vacuum chamber but using simple microwave bowl ...works perfectly for me.
Wow! Great! 👍
would this work in reverse as an inexpensive pressure pot?

I wonder if it will work with silicone? This is great thanks for sharing 😊
Thank you! Silicone is denser than resin. It might work if you do even lower pressure and have more curing time.
@@withthebestwishesforyou8308 You're welcome and thank you for your reply. Hopefully I get a chance to try it out one of these days.
Ok...
This is most likely to be a stipid question but....would a food saver with an attachment for vacuum sealing mason jars wprk 6:02 6:03 6:11 😊

how many times did you have to apply and release the vacuum pressure to get the final results?
It took three runs to get rid of bubbles. The warmer the resin, the faster the bubbles will release. To get the best result you can place cans with resin in hot water for 20 minutes before the procedure.
can you get to -30 with this setup?
I haven’t tried doing -30. But most likely we'll need a jar with thicker walls. I'll let you know if I try.
where should I buy such a pump first?
It's Vacuum Pump Tester Set. You can order it online or buy at any auto store.
@@withthebestwishesforyou8308 thanks
vacum pump 12v will work with same result?

ok i will try your solution, i need this degasser for silicon mould
@@withthebestwishesforyou8308 just do a quick job with this pump, it work until to -20 😮😮
i just try and it work until-25 very good 👍🏻
To hard with out words

I'm really sorry about it.
