I have my Pressure/Vacuum Chamber (pot) almost completed and hope to order my supplies to be in casting test mode in a few days.
My questions for those of you that are casting currently or have cast in the past:
1. What pressure do/did you find most successful...
2. What duration do/did you require for the cast...
3. And what material(s) were you casting under those criterion...
I can easily maintain 70 PSI and the tank is rated for 100 PSI. I still have a couple of small pressure leak issues to resolve but I get 20-30 minutes of 70 PSI before the compressor cycles back on. I am trying to see if I have an acceptable pressure system currently, just in case I cannot get the remaining leaks closed in a timely/affordable fashion.
Next is the Vacuum Leak Test.
Thanks!
