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. "Jim Weir" wrote in message news ![]() 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. Jim "Gig Giacona" shared these priceless pearls of wisdom: -How many are you doing?

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. Rich S. |

Counselor http://www.rst-engr.com 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. - Holger Jim Weir wrote: 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?

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! ;) Bushy |

Counselor http://www.rst-engr.com 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. Tom Pappano, PP-ASEL-IA |

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.
