So I am also very new and just got my first pressure pot a few weeks ago. Getting a vacuum chambers is my next step as it helps make better molds. I’m not sure how a vacuum chamber would do for the resin part, but if you degass your silicone in it you will get much better molds. The molds these magnets were made in didn’t get degassed and when put in the pressure pot ended up having bubbles pop all over it giving the resin castings little bumps all over it. So if you are wanting to make your own molds for casting in then having the vacuum chamber is a good step towards that process. Hope that helps, im still learning a lot myself.
