[TheForge] Fwd: fridge compressor?

Wed Nov 26 12:21:00 2003

While I think that most fridge compressors are too small to supply much air
for many shop uses -- they do make very good vacuum pumps.  Very useful for
"woodworkers" using vacuum bags for clamping veneer etc.  Never know what a
blacksmith my want to use vacuum for.  Now Air Conditioning compressors
could be of a much larger size.  Still you don't find many scrap AC
compressors -- while there always seems to be a lot of scrap fridge
compressors.
