got all my gear and adapters.. havin problem with getting pressure into the pot..maybe I have a faulty gauge part.. strange... no leaks tho
thanks.. finally got mine goin after a few rearranges .. got a few molds done and a few more this week.. molds always the boring part
Resurrecting this thread to ask a question about moisture. I'm using a converted paint pot as a pressure pot and when I release the pressure I definitely notice a little bit of moisture spitting out of the valve too. Not a lot, but noticeable. The casts seem fine so far but just looking for advice. Is the solution simple as putting a moisture trap between the compressor and pot? By the way, I used this video as a guide to convert a Harbor Freight paint pot. Worked like a charm. The only bad thing about that video is he didn't really go into detail about the regulator and blow off valve. Both of which need a lot of tweaking. It works really well.
If you have a moisture valve on your compressor, you’ll need to open it and drain after you use the compressor. If you don’t, you’ll need to get a moisture catcher. Urethane hates water. Harbor Pots take about 15 mods to get working correctly. I use 3 and they good.
Thanks Neil! Shopping around for a moisture trap now. That sounds like it'll be the last tweak to my resin casting setup for now, to get up-and-running. I'm also in the market for a regulator. I usually use my small compressor for airbrushing but I also have a huge shop compressor (which is what I'm using for the pressure pot)...and I figure if I get a regulator + moisture trap then I don't see a reason not to use that for airbrushing as well - at least sometimes. Sort of random side question: Any idea what PSI a giant shop compressor like this blows air out unregulated?
A regulator is extremely important to run any air compressor. A harbor freight pot has trouble holding 60 psi. There’s no use wondering about how much psi that compressor can push with out a regulator because, it’s unsafe to hook that thing to anything with out a regulator. if you’re running an oil-less compressor it should have a drain on the base of the tank to drain the moisture. You should drain it after every use. Especially if you’re in a humid area. Otherwise that tank will take on water, rust and rupture.
I do have a regulator attached to the pressure pot, I definitely would never use it without one! I was talking about a secondary setup where I would attach a regulator to the large compressor so I can throttle the PSI for airbrushing.
