It appears the chamber is not holding a vacuum. The pump and gauge check out (see previous post). But with the chamber attached, I can’t even get down to 5e-2 torr (the top of the gauge’s range) after running for over an hour. So Houston, we have a problem with the chamber.
Also f*ck WordPress for blocking posts with the word f*ck. What are you? my f*cking nanny?
