OK folks, here is my set up. HF pressure pot with a robinair 6 CFM pump. Thanks to all on the casting forum, I got plenty of ideas and set-up examples from there. While putting this tigether I learned "Flair", NIP and MIP are and how the threads are different etc. [:I] Anyway, I tested it on vacuume and almost made it to 30" of vacuume (see pic) it held at the same vacuume for 24 hours so I guess it seals well. The pressure though, I tested it up to 80 PSI (the pressure pot max) and within 4 hours it went to 70 PSI and held for a while. At the 24 hour mark it was down to 60 PSI...so something is leaking. Overall I am pretty satisfied, now once I pay Gadgett for the molds and get them I am all set.[]
