Any one ever use one of these vacuum pumps to vacuum bag?

Harbor freight sells a cheap vacuum pump for less than 10
bucks. A lot less
trouble than going with the idea you are entertaining.

This is a venturi pump that hooks to an air compressor. My experience
with the one WEST sells was that it lacked the volume capacity for
anything useful. Possibly I didn't have the right technique to seal
my edges properly but my compressor was running continuously and I
could not keep up with anything the size I was interested in.
