Was wondering what’s an economical way to do this. I assume you do it separate encase the pot life is short but in any case what does everyone use to do this?
A good vacuum pump, and a pot with transparent lid. Put your resin in a wide / large bucket, degass until the foam starts to come up violently, give the complete pan a couple of good tosses, so the foam implodes (you might need to lower the vacuum temporarily, to prevent the foam from reaching the top of the container), weight another minute or so, and you are done.
And is this 100% necesary? Is it bad if degassing it is omited? I have done some small trails just to confirm the infusion process, I did not degassed the resin, I did not see any issue, maybe is it essencial for large parts?
Can you give some examples of a pot? When you say that I think of a cooking stock pot with a glass lid and little hole for the steam to release.
I’m guessing I could use disposable mixing containers depending on the batch size to do this that way you’re not cleaning out the pot and mixing old with new resin if you’re reusing the same pot right?
“I’m guessing I could use disposable mixing containers”
For doing small parts I have used large glass jars I get them free from the local chip shop the type they store pickles in. The link below shows a small jar and cheap catch pot but you will get the idea. You do need to test they can with stand the vaccum, I have not had any break on me yet.
You know what I just re-read my quote and it does need to be glass or something that can withstand pressure.
So I basically just get a jar, put resin in the jar “mixed or unmixed”, seal the top, poke the hose in the top, turn on the pump and watch as bubbles “if any float and pop”. After that’s done I just lower the hose in the resin to infuse right?
If I’m pulling to much vacuum I just kink the line too right?
I found this video too so if anyone else needs reference this is good as well I think.

You want a valve that you can control. Sometimes the foam goes really fast to the top.
For some reason the website’s not loading to well for me. I’ll check on my work computer tomorrow.
Also didn’t get a link to the video you’re talking about. But thanks for the help thus far herman. I’ve read a good amount of your posts online from previous topics that I’ve searched for!
I see this website could use an update.
The video:
Ok awesome.
So basically it’s just a stock pot with a piece of lexan glass or something similar that won’t flex and the pot has a hole cut out with a fitting for the vacuum pump.
Thanks for the video!
Yes, that is basicly it. Wax the lexan and the inside of the pot, so resin will not stick. Accidents happen…
Im just a Newb and all the stuff i do is small but what i do is after i mix my epoxy i take the mixing container and stick it in the microwave for a few seconds. After that i let it sit for a few minutes and viola! the bubbles are all gone. Because of the heat it kicks real fast so if i want to slow it down i will stick it in the fridge for those few minutes im waiting for the bubbles to pop. Anyone else ever tried it this way?
