Brian, I sent you a note, too. Most compressors using R22 also have oil mixed into the freon, to lubricate the compressor. Is this addressed in the article?

Also, I recall a post about materials used. Something like nylon peel, scotch-brite to absorb the excess, and another readily available, cheap material for the bag. Anybody else remember that?

: Bruce, I recently found an article on constructing a vaccuum bagging pump for
: ~$20. The author calls it the "Cheap Sucker". The premise is
: that you use a refrigeration pump from a cast off refrigerator, after
: properly recycling the freon. If you're interested, I can email you the
: text of the article.
