This is my roughing pump(or at least it will be).
Its an Edwards Speedivac ES150. An antique I know!
Anyway, this is what started me in the way of vacuum. I pulled this out of a skip in The National College of Art and Design, Dublin.
I got it home and cleaned it up a bit. It looked terrible. I suspect it had been used for degassing of plaster and resin.
I began to read about rotary vane pumps and got it moving again.
With the help and advice from a generous man named Eoghan Murphy from Vacuum Spares in Cork, I tried light grade motor oil to see if it was completely fuckt of not.

Well, a lot of brown gunge came out when I emptied the old oil. I replaced it with new oil, spun the pulley a few times and switched it on. And off it went!!
