Just got my August FWW. Still worrying away at a ‘shop-built’ vacuum set-up (actually, the guys at the aircon and refrigeration shop are making me a vacuum pump, and I’ll make the bag – eventually) and there on page 30 is an interesting looking modification of the wine bottle vacuum set sitting in my kitchen drawer!
Has anyone tried one? How is the ‘valve’ attached to the bag? Looks like a viable option for my small veneering jobs!

Malcolm, I have been bagging quite a while now, and when I am teaching newbies, I like to show how simple it can be. I'll bet that if I were to walk into your shop I could show you how to use only things that you already have on hand.
I will be giving a weekend workshop in my shop for the local woodworking club. I will probably start with a demo like this. First I will take the intake filter off of my compressor, and with off the shelf pipe fittings from any hardware store, hook up a hole on the intake, and open the tank. Wala! I have a 2 hp pump. Total cost. Under $5.
OK run the other end of the hose into a large zip-lock bag with the work in it. Take a big wad of chewing gum out of my mouth, stretch and wrap it around the hose right were it goes through the zipper and you are done. It can be that simple. However there are many many tricks to learn to use this technology creatively.
Any caulk with a heavy body will work, and is easier to use. If I wanted to do something larger, like a cabinet door, I would use a large drum liner size trash bag. I would bring the hose through a bottom corner through the caulk wad. You can seal the big end by rolling it around a dowel or a square for that matter with another strip clamped to it with spring clamps.
One of the great things about vacuum bagging is that you are not limited to size. If you wanted to make a panel as large as your shop, I can show you how to do it, and it doesn't have to cost a lot of money.
I know some of you will think that I am full of it for making a claim like that, but it is true. Some of you may be members of clubs, and I would be willing to travel around to give weekend or day-long, hands-on demonstrations.

The more things change ...
We trained hard, but it seemed that every time we were beginning to form up into teams, we would be reorganized. I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency, and demoralization.

I've looked at your web site, and I believe you! When I get a pump organised, I'm not too concerned about making bags.
In spite of Joewoodworker's cautions, I'll spend a bit of time this weekend experimenting with a hand pump, as in FWW. They sure suck the air out of my half-full wine bottles!
Cheers

I'm sure it works fine for a wine bottle, but in the real world of vacuum bagging, if you have even a tiny leak as small as a needle, you will be stuck pumping until the glue is cured. You will have expended so much energy, you will feel like you just ran a marathon.
Why didn't I think of that!!??
I've been looking at vacuum bagging for a while now but haven't wanted to spend the money for a pump. Those hand pumps look interesting, but again, it's a matter of not spending money on something I may rarely (if ever) use.
However, I got ziploc bags and 32 gallon garbage bags up the wazoo and I'll bet that a quick tour thru my small fittings coffee can will turn up what I need to modify my compressor. I may just give it go this weekend - lol.
Kieth, if this works............you da man!!
Cheez, where'd this emerge from! Discussion started months ago!
Let me know how you get on ... there's a supplier in Australia who sells commercial kits that use a bottle pump.
