It would be nice if someone could come up with a way a compressor could
serve a dual purpose such as a vacuum pump in addition to an air compressor.
I was thinking about inventing some kind of a diverter that could be
connected to the air intake port of the compressor with tubing to a vacuum
bag for gluing laminates. Have any of you out there heard of such a thing or
is that a dumb idea?

Yes. A venuri-based vacuum generator uses a compressor to drive it. But
instead of using the compressor intake, it uses the output compressed
air.
Its not as efficient as a well designed vacuum pump, but it does work.

I use a recycled refrigerator compressor as a vacuum pump. It works
fairly well.

My lash-up is shown under the end of the table in the fifth photo down
at the page below. One of the problems I have is that it doesn't make
/any/ noise to remind me to shut it off...

Just MHO, but I like multi-use tools about as much as "all in one package"
computer software...
