Just thought I'd post a couple of pictures of the vacuum pump I was talking about last month. It's a little Edwards ED 35 two stage pump which I found in a local laboratory's skip (dumpster) last year and have spent a bit of time restoring. I had the motor rewound, repainted it, stripped and cleaned the pump and fitted new springs and seals, and mounted it on some anti-vibration feet. Now it works very sweetly and holds its vacuum for more that a week after I switch it off. I'm planning to use it for some experiments on electrical discharges in low pressure gases. I'm meaning to create a web page with some pictures of the restoration, but so far I haven't got round to it, so I thought I'd share a couple of pictures.
