Okay so I did bring my little Gast pump to Texas.? ?That's the good news.? ?The bad news is that the motor is 240vac.? And I haven't added the additional 240 outlets I need to for range,? tube furnace,? welder,? etc. next to the door where it's convenient.?
It's a Gast 0211-V87 pump.? So before I can even test it I need to either do some wiring or temp splice a dryer cord onto it to plug into my compressor outlet tucked way back in the corner behind the South Bend vertical mill.?

Nick that looks like a
rotary vane type pump that uses oil which is going to be very bad getting into
that detector head. I would absolutely not use anything that had oil involved.

Well I shoved the cord wires in an extension cord and it actually seems to run okay on 120vac.? Sounds pretty good,? not too loud.? ?If I completely plug the inlet hoses it slows down enough to kick in the starter again though.?
This model should be rated at 1.1-1.3cfm.
I think I'll install a proper 120 plug on the cord and hook it up to the SmartCAM and see what airflow it reports.?

Nick I have a oil type
pump on my vacuum oven and it uses scrubbers on the exhaust as there is quite a
haze without it. Do you get an oil haze out of the exhaust port? ?All that is going
back in so use an exhaust filter. ?An inlet filter will prevent oil back-streaming
from the pump to the evacuated chamber which is why these are used on alpha spec
systems. I would be wary of using ?that pump for that purpose. Get a diaphragm type
pump there are plenty on Ebay around $100. I also realize that we’re not
dealing with a closed vacuum system but why take chances. At the very least
disconnect the vac line when finished as diffusion rules.

WHAT? You have all that stuff and no stout 110/220 test transformer with metering??

Good points,? and I was wondering about that because I don't want to be breathing oil mist either.? Will check for oil on output but for sure install a catch filter if there isn't one in the bottle on the outlet.?
All of my pumps are oil (except the turbo) types.? My experience with diaphragm types is that they fail...? Aquariums mostly.?

That's what I say 20 times? a day,? Today it was looking when the shed project needed a piece of sheet metal sheared, and I could see the shear in the garage, but would have had to move the welder, band saw, tables saw and two cabinets to make a path to it! GGGrrrrrrrr.....
Wound up cutting the metal with a hand snips,? DOH!
But when the metal building is finished, this week we think, all will be better, every tool will have a permanent home.
