Hello! I am new to mold making / resin casting. In trying to make some molds, I’ve run into an issue where my pressure pot will not hold more than 10 psi. It will hold the 10 for a long period of time, and I can’t identify any leaks, so I don’t think that’s the issue. I think the problem might be the safety valve not allowing it to go past 10, but I have no idea how you’d adjust a safety to let it go higher? Or if it can’t be adjusted and I need a different one? It’s your standard air compressor safety valve with the ring at one end and a spring in the center. Any thoughts or help at all would be appreciated–like I said I’m new at this!!
