I've had to back burner my vacuum stuff because I've decided to retire from my day job which included a 3500 sq ft shop to play in right now i'm moving stuff into storage untill I can find a home for it all. I was trying to pick up vacuum guages on e-Bay and haven't gotten anything to work yet. (Often best to just buy it new) try using? glow discharge as an indication of your vacuum if you can get to the low millitorr range the?glow should be impressive. this will give you an indication of how long it takes before you can start a diffusion pump if your looking at hours to get the pressure down than you 'll at least know the pumps you have don't work.
