I would check out "the Bell Jar" for all sorts of useful info on amateur vacuum. And, there's been some stuff over the years in the Amateur Scientist. Of course, during the C.L.Stong days, there were lots of vacuum related things, but also more recently.. Shawn Carlson had one on a LN2 operated sorption pump that works quite well.
