Tiny vacuum pump

Does anybody have an idea on how to make a tiny little vacuum pump on the order
of an aquarium pump or so that will draw just a few inches of water? Preferably
110, but I can rig up a 12 volt supply if necessary.

The reason I say this is that I'm getting ready to pack a fairly large number of
bags with used but serviceable engine parts (valves, pistons, etc.) and I'd like
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?

If it is just the suck that has to be tiny and not the pump, how about
a toilet paper roll and some duct tape to make an adapter to your shop
vac?

Why don't you just get a foodsaver? (www.foodsaver.com). It will do the
vacuum pack as well as sealing the bag (and you can make arbitrary sized bag
as long as it's narrower than the roll of "bag stock." I've got one in the kitchen.

If that's too pricey for you, then there's always this one $14.94, not sold in stores....

You just need a surplus dental spit sucker. Perfect for removing air
from the corner of a plastic bag.

Because the pump has to fit on a bench that is already overcrowded. If I was
going to use a shopvac, btw, it would be with a pvc waterpipe fitting glued to a
barbed fitting with plastic tubing. I thought of that and then the hassle for
each part of reaching down to turn the vacuum on for each part you want to seal.

Because Foodsaver requires you to use their special bags. Besides being WAY
overpriced, the bags ain't cheap either. Yeah I knew about pump'n'seal, but
that seems to be a kluge way of doing it. I was looking for elegant.

If you have a compressor, use a venturi vacuum generator.
Harbor freight has them for about $10 from time to time.

My wife bought a vacuum bagging freezer food storage system. It sucks
down the bag containing the food, and then heat seals the edge of the
bag. I have used it to seal electronic parts into bags. Should work fine
with a little preservative oil on mechanical parts.

PERFECT. Where do I find one? Are there boneyards for dental equipment?

How many are you doing? A drinking straw and your lungs will do a bang up
job with a zip-lock bag
