I've had good results with a food saver...and there's the added bonus that the wife was happy to spend money on it.

How much money do they cost?

This is the one I have: http://www.foodsavercanada.com/product.aspx?pid=9081. I think I paid about $150 for it. There are cheaper ones out there. I know I could get a good vacuum pump set up for about that price, but a happy wife is a good thing.

With the food saver you have to be really careful about sharp points on your mylars so you don't puncture the bag. I've read about guys ruining projects with a minute leak. I have not had the problem yet in about 6 bagged projects of various types. I don't have a lot of experience with it yet, but what I have done has turned out very good.

That can happen with just about any vacuum system.
I almost spoiled a project and burned out my fridge compressor pump due to, what turned out to be, leaks in the plumbing "T" junctions in the pump system itself. The tube dries out and with some movement, it can result in a poor fit over the barbed fittings.
The first thing I do now if I have a slight leak is pinch the vinyl tube closed between the pump and the vac bag. If the vac system stops cycling, the problem is in the bag. If it doesn't, its before the pinched shut off point.
The bigger leaks can be heard of course.

Jim.

Not managed to bag a wing yet.

Had too many distractions and not enough time. It also doesn't help to have a dump of snow with sub zero temps. My work space is in a very cold garage.

But, I've managed to convert an aquarium pump. It took two pumps as the first had an integral valve which could not be reversed. I don't know if works yet to bag a wing but I hope to try in a week or so.

Does any body have a good recommendation for a bag valve system? I'm struggling to come up with anything?

Purchase a tire valve at your local Auto parts store.
http://www.napaonline.com/Catalog/Ca...282_0215254711

I spent about $5.00
Drill the innards out.
Then cut two crosses in the bottom of it to keep the bag from sucking up in the hole and shutting off the vacuum.

I took two photos, the quality isn't very good but you should get the idea.

That's it.

Cheers cloudyIFR,

I can not find a car tire valve? A bit weird.

However, what do people think of this?

http://shop1.r-g.de/4DCGI/ezshop?act...COUNT=62598896

Should do the job, not too expensive and should connect to aquarium tubing?

BTW, cloudyIFR, is the IFR I Follow Roads, rivers and railways?

For what it's worth, I no longer use any sort of skin fitting for my vac bags. I simply wrap the end of the vinyl vac tube with some paper towel and/or some peel ply (Taffeta) and run it out between the bag joins. I use acrylic filler for sealing the bag and this also seals around the suction tube.

On wing moulds where the bag is only one layer sealed on the mould flanges, I use a small length of tacky tape wrapped around the tube to secure it and prevent any sucking in of the acrylic filler. Then the filler runs over the tacky tape etc.

Jim.

edit: I also use cheap, universally available drop sheet plastic for my vacuum bags. Cheap and disposable. Very flexible for following internal corners and such.

Hi all,

I brought the bag valve I linked in the previous post.

It's now doing a sterling job on my first bagged component.

I took off the push fit adapter, heated sone aquarium tubing in some hot water to make it pliable and pushed it over he fitting. Job done and a good seal. Not to bad for €20 or so.

Will be able to tell if it worked tomorrow.

Aquarium pump seems to be doing the business. Not sure what its pulling but it is defiantly pulling.
