Does anybody know about vacuum pumps homebrewing??? :-)

A LONG time ago (maybe 40 years?), Scientific American carried an article
(in "The Amateur Scientist" pages) about making a vaccuum pump. (It may
have been part of or near an article about making your own laser which
was strong enough to bounce signals off the moon!)

You can get a reprint of this book from Lindsay books
