I am looking at making my own resin catch pot I just wondered if you guys could post pics of yours for inspiration. I work with metal so thats not a problem. Cheers!
Here’s a picture of the first resin pot I built.
Works pretty well, but after a few botches infusion I can feel it getting heavier with resin. I can’t open it so when it fills up I’m just gonna chuck it in the trash.
I would recommend buying this pressure pot and moding it to have the fittings you need: http://www.harborfreight.com/2-1-2-half-gallon-pressure-paint-tank-66839.html .
not a bad price is it! Do you know how they seal?
they work really well, they have a good weight and low center of gravity so they dont fall over. they seal up really well, just make sure after adding all your fittings to do a leak check before putting in service.
I have that one too. Once you get vacuum pulled on it the lid clamps down tight. Just remove all the paint fittings and put your own fittings on. I put barbed fittings on mine.
I was in the garage of a friend I used to work with who also fixed AC systems. He had a glass jar which he had brazed in two brass barb fittings into the lid. I always thought this would make a great (and cheap) resin catch.
This is what I made at work!
spot on, what did you use as the seal on the lid? rubber sheet?
I turned a groove in the lid and made a seal out of some 4mm neoprene sheet we have. I had to cut it out with a knife though so its not perfect. Holds vacuum though. 
Oh also used loads of wacker grease around the seal
Also been sat a 28.5 hg for 8hours and another pic

Hmmmm which one should I get? Both are the same size one is $80 and the other is $300. Hmmm :blink1: Thanks for sharing hojo. If I ever decide to buy a real catch pot I will go with the $80 HF. Currently I have something like Canyons setup only in a 4" dia. pipe so it can hold more resin. Only thing is I never get resin in it because of when I shut my resin of so it’s lasting me along time.
Because Fibreglast is a ripoff!!!
Also, the HF one doesn’t come with the right fittings, or vac gauge…but that isn’t much money.
No problem. Fibreglast is a complete rip off. You can buy that same pressure pot for around $100 elsewhere, but I dont like those ones that much, they are taller and lighter and not as well made. the ones from harbor freight are heavy and fatter, so they wont fall over and the quality is much better.
I bought my HF pressure pot for 40 bucks from Craiglist, vac gauges and fittings were another 20 bucks although mine required a fair bit of cleaning before it looked decent and worked.
I am having them made by another company for me. Basicly they are cooking pans, with a vacuum connection drilled and threaded into the side, and the lid is a thick piece of acrylic (on the large one the sheet is 30mm thick, or about 1-1/4" thick. In that are a vacuum gauge, and 4 push-through connectors.
Have them made in 3 sizes now. (10, 25 and 70 liters)
I also made them from PVC piping, works as well, but no see through lid.
to bring up an old thread here
What is on the inside of pressure pots? I’m not quite sure how they work aside from just allowing gravity to pull down the resin and keep it from going to the pump. Is there a media inside that physically traps the resin as goes through the pot?
at most you will have a removable bucket for easy cleaning.
Indeed, just gravity.
Basicly you want a pot that will not collapse under vacuum. The pots I produce do not even have a clamping system (not needed). Preferably the lid is see-through, or has a window (or 2, for a flashlight). The trick is in the fittings on top. Although you can use about anything, you would want something that you can stick a pipe (vacuum line) through, seals completely, and does not get clogged with resin.
Apart from purpose made (expensive) systems, there are 2 options that are attractive: pneumatic pushin fittings, which will need drilling out from the bottom, or watertight connectors from the electrical industry.
or compression fitting from swagelock. Just push the compression rings on, push the tube through and screw on the nut. that way any resin doesn’t get in the fitting.
Whiterabbit, we just use bucket liners. thin plastic shells. Anything really. Some people just release coat the inside very well, and wack out the blob of resin after it cures. you don’t have air flow when the resin is dripping in the bucket, so you don’t have to worry about the vacuum sucking the resin back up, mid-air
