I purchased a 12CFM 2 Stage Rotary Vane Vacuum Pump from eBay and is the cheapest one. I ended up buying another one. Anyways my old ones motor broke so my best friend when he was.living with me at the time found an ac motor and decided to try something and it worked a lot better than expected. It went from 0 to -30Hg in seconds. It’s a 1725RPM A.C Motor attached by a brass pipe. The only thing I would.need.to do.is.get a new motor and house the pipe. Other than that if anyone wants to give this a go.with theirs then I say go for it.
The motor was.in my basement and has.to.be from.the 80’s.
The cord ended up.shorting and burning out. It worked.though before it shorted and burned out
