Dan and Bill- Thank you! I just needed some quick advice to keep the project moving during the holiday break, and I appreciate it. The motor is on the stand and I'm removing parts/ cleaning etc while I wait for the manual to arrive, and was a bit confused about that VCV, as it looks like it may also have the shutdown as part of its function. I will post photos as it progresses. Haven't decided if I will go with an electric vacuum pump, retain the original, or just make up a mechanical shut off.
