Expert opinion on Vevor Vacuum System for epoxy resin: Is it worth $300?

[@davedev5427]

Nice tests

[@maplewoodworks]

Thank you.

Great video. The tests were a real plus. Just bought the 5 gal 3.5cfm pump, $121 from Vevor with free shipping.

[@maplewoodworks]

Thank you for your comment. That is a great deal, wish i paid that. LOL

[@donferron5352]

With all my questions answered, tomorrow I will do my first pour using the chamber. Thank you to all who took the time to address my questions and concerns.

[@maplewoodworks]

Glad it was helpful! Let me know how it goes. Good Luck!

[@donferron5352]

Would you suggest degassing epoxy before pouring? I have a 16" pizza cutting board in progress and ready to pour. The board is mainly red cedar rounds. I will be using epoxy that supports up to 400*.

[@maplewoodworks]

Hi Don, Yes, absolutely. I degas every time. Takes 10 minutes and my epoxy comes out like glass.

I just got mine wed...4 days ago. I'm at 800m elevation. It's a 5 gal tank. It got to -28.5 bar or 99.94 vacuum and has held it (all valves closed, pump off) at -28.5 bar till now!!!!

[@maplewoodworks]

Hey John, Yup, I must admit I love this vacuum chamber. My resin is 10x clearer. Do you do bigger projects or smaller ones?

[@kellyjean4981]

I Appreciate the review. Is the vacuum chamber still holding up well?

[@maplewoodworks]

Hi Kelly, Yup, I use it regularly and it's still working like new.

[@donferron5352]

HELP!! Appreciated.... Will a Vevor 5 gal vacuum chamber work well for turning projects? I just purchased one from Vevor and now not sure if I should have considered a pressure pot. Would I degass the resin and then pour into my container with the wood and let it cure, or degass with the wood and resin in the container?

[@maplewoodworks]

Hi, I don't think you need to worry. Mix your resin then place it in your vacuum and bring it up to -25 bar. Once all the bubbles are at the top, torch the top to break all the bubbles and SLOWLY pour it in your resin into your container. be carful no to introduce bubbles. Monitor your project and torch the top of it every hour to ensure all bubbles are broken. Let me know if you need any additional help. Robert

@@maplewoodworks You answered my concerns, too. Thanks!

[@jheikenfeld]

Great honest review

[@maplewoodworks]

Thank you. It's still working great today.

[@donferron5352]

Do you leave your project in the chamber until solid? What happens to the bubbles after the chamber is returned to atmospheric pressure? I viewed another video in which a lot of foam was developed.

[@maplewoodworks]

You may have to use the vacuum chamber 3 or 4 times for all the bubbles to come to the top. Every time you put the resin in the vacuum and bring it to -25 bar, let it sit there for 5 minutes then slowly let the air back into the chamber and remember to torch the top of the resin. repeat this 3 or 4 times until the resin is clear.

26 Bar - A bar is 14.7 PSI (1 Atmosphere) the most one can vacuum is 1 atmosphere, which is also 100 kPa. The numbers you are using are metric and this may the issue as I assume you are located in the USA. 26 bar would equate to 26 x 14.7 = 382.2 PSI and to the best of my limited knowledge there is no vacuum pump on the planet that would achieve this. Apart from the math the video was interesting - all the best with you future vacuuming.

[@maplewoodworks]

Thanks for the correction, I am still learning all the conversions!

[@christopherwalker283]

Think you are seeing inches of mercury in/Hg again the max would be around 30 inches of Mercury

[@maplewoodworks]

Thank you for letting me know. I think I need to do some research.

[@carmenencarnacion2510]

can I use 1:1 ratio resin? I would like to know if the resin doesn't harden while it's inside the vacuum and then become sticky before use it. My purpose is to use it for flower preservation.

[@maplewoodworks]

Hi Carmen, Thank you for your question. Yes, you can. As a matter of fact, the first resin I show in this video is a 1:1 ratio resin. The one thing to look for is the "pot life" of resin. Your resin should say something like "45 minute pot life", that is the amount of time you have before the resin starts its exothermic reaction (in other words, when it will start to harden). Also, keep in mind that if it's in a cup like I put it in, it will harden a lot faster because of the temperature of the resin rising. Please feel free to post more questions if you have them. Robert
