Title: Vacuum bagging supplies
Post by: Fred on September 23, 2009, 09:55:52 AM

Bill, where do you find Vaccum wing bags ?
I have an address in France, cheap, but now, the shipping for Ireland is going crazy !  :!:  :!:

I've heard of some bags you can find in Homebase etc etc  :?:  Any clues / reference ?

Fred,
do you mean the bag for putting the wing and fibreglass iin and then sucking down to vaccum to give a nice shiny smooth finish?

If so the stuff you are looking for is called layflat tubing. Comes in a variety of sizes on a roll, is basically a tube of heavy gauge plastic. used for things like ptting rolls of carpet in and also used by farmers. Four our purposes th 12" width is the usual.

I've also used the bags you can get for putting you duvet in that you se advertised on the tely sometimes for space saving. If you go that route try and get the ones that use a sealing strip rather than a zip. I got a couple of ebay for under a fiver. Will have a look later and see if I can see any. These are only good for smaller wings.

A google search for layflat tubing will probably find a local supplier.

Mylar or getting the surface finish is the really hard stuff to find. you need it 35 micron thick for best finish

Hi Bill,

Yep, for the wings.

The one I use to have is 2euros/m, 60cm wide...
If interrested, I can negociated a group buy, and we share the shipping  :?:

Anyway, I have a look for the layflat tubing thing type in Homebase and Ebay  :D
I let you know what I found, might interrest someone if that is cheaper.

That's a pretty good price Fred for small quantities.

We would need to know max chord size anyone would be doing to make sure we get wide enough tube. 60cm /27" would do around 22"/45cm wing chord. Plenty for most purposes.

Found this on ebay.co.uk

15" wide, do about 12"chord. they'd probably add postage as free isonly mainland UK

For the layflat tubing

http://www.polybags.co.uk/shop/standard-layflat-tubing-7-15-wide_c1015.htm

10" x 120 gauge x 700m long is £34 and shipping is £8

That would do us a life time. Not sure if this is heavy enough gauge??

Count me in. I would like to get into vacuum bagging.

Most of the bags I've used are 250 gauge, tends to wrinkle less

I got a quote for mylar last week of £90 for 350 micron. 10m x 914mm +£26 postage. carraige seems a bit steep. Anybody know anywhere cheaper?

About the same price. Not sure about carriage??

Thanks Joe,

You'd think in the whole of Ireland there would be a supplier, it must have uses other than modelling!!

Alright lads, I have splitted the original subject, and created its own thred !
Lots of usefull info in there !

Bill, I have another question for you !
Where do you buy your Vacuum connector ? The one that goes on the bag ?
Used to buy that many moons ago to Topmodel in France for the club, but there might be a more local supplier (and certainly cheaper too!)

Joe,
I buy mine from the US! Joewoodworker.

You can also get them from Tygavac in the UK and there is somewhere else to.  

Will check my PC at home tonight.

Could also look at

https://www.airtechonline.com/htm/defaultIE.htm

Most of their stuf seems to come out of Luxembourg and is priced in Euro. Not sure about postage, but other prices look OK

Thanks again Bill for all these info !  :clap:
Checking a few things, but each time, shipping is the killer !  :!:

We probably need a group order then t save on shipping. R-G do vacuum bagging stuff too and I know Joe is talking about an order to them soon. Maybe look there and see if higher price outweighs carriage costs?
