Sealing food bags is where I came up with the idea. I did that until my wife
reached her tolerance level and went out and bought one of the vac/sealer
thingies.

That's how I seal food bags for freezing. Tellya what, put a little light
machine oil in a bag and try sealing it with a straw. Damn near choked me

to
death.

When I bag salmon for the freezer, I fill the small kitchen sink with water,
then submerge the bag in the water up to the lip. A quick zip and the bag is
closed. Not a big enough bubble left for a compass. You could use a
Tupperware container instead of the sink.

to put each part in a "baggie" (sandwich bag or equivalent) along with a little
preservative oil, and then suck the baggie down with a football needle stuck
into the top closing mechanism just before sealing.

Thoughts?

How about a MytyVac (
www.mytyvac.com ) from your local auto supply.
Vacuum and pressure ports. You can use it to bleed your brakes with
the included container, hose and connectors. Or pressure test your
radiator. Hand powered.

Elegant solution might be a penis pump from your local sex toy store.
Probably should check the duty cycle, though. )

Sex toy? That's a medical device, honest!

Anybody mentioned a refrigerator compressor? I used it to vacuum bagging
composites. You shouldn't drain the fluid from a filled system (ozon
killer) but if you get one from a bone yard that is already drained it
would make a low noise, low cost solution.

Take the brake system vacuum pump from the back of the alternator on almost
any diesel light truck, 4wd, etc. For the level you are looking for you
could probably hand crank it with a lawn mower zip starter and use it's
return spring to set it for the next pull.

Depends on how green you want to be, you're both recycling and people
powering it!

If you have compressed air already available, there are small venturi
vacuum generators you can use. They are just a tiny chunk of
aluminum with three 1/8" pipe threaded ports, air in, air out,
and vacuum. The one in my "solder sucker" pulls about a
26" vacuum and damn quick too! A "baggie" would be evacuated
almost instantly.

Those aquarium air pumps pull air from around the case.

How about placing one inside a cheapo tupperware-type container with a
"suck" port mounted on the container, you'd also need to run a "blow"
port from the pump's normal output through the container wall.
