17 - How to Make A Vacuum Bag for Veneering

Watch our latest video : "From Old Firehouse to Woodworking Wonderland | Shop Tour 2024"
This video was published May 31, 2007 & was never added to YouTube...until today!

The results of this little project are not exactly what you might expect. It was quite a learning experience. If you are considering making your own bag, this video is a must see!

i think your vids are the best we dont like to see you fail but it gives us a piece of mind that your not trying to pull a fast one either

14.7 pebble per square rock? Wow!! Seriously- thank you for the video, exactly what i needed and searched for. Excellent work.

[jochenwulle]

As a boatbuilder i have been bagging for some years now in and on odd shapes, Yes each one has its own twists and problems ( convex-concave 20meters??? the list is there) But for flat table work why do make it so hard for yourself with the glues etc??
(9 times out 10) i use 2 sheets of heavy plastic sheet to fit the job and seal it with brown packing tape, , , job done, Also i lay a plastic net ontop of the work to allow the air to travel ( inside the bag) try, , good fun, regards rik

nice job 
the fact that your finished product was not as expected is actually cool of you to publish your vidio. ., . .   because you are correct that some folks may not actully be successful.   THANKS BRO.

Looking to do a skateboard build for a youth group and so pumped to see your page was the first that came up as ive been following you for years!!! Any tips when it comes to smaller applications for things like skateboard sealing bags?

[thomasreynolds]

Honestly I DIY to figure out everything that can go wrong. Showing the failures is more useful to me than the one example of getting it right.

Hi, enjoyed your video - I want to make a vinyl bag like yours but could you tell me the thickness of your material, please? Thank, Colin in UK

[billtiffin]

My first pre sleeve video Now I'll be watching older videos to see it develop

[jimmyjimjimmyjimjimjimjim]

Thank you for showing the failure. Personally, I find videos with all the mistakes left in more informative than videos where everything goes perfectly. I made a vacuum pump out of PVC pipe and about $40 worth of hardware, including a venturi valve which creates the vacuum. It works off my compressor and I've found that it works as well as, or better than, any vacuum pump at a fraction of the price.

wouldn´t it be advisable to use an FLAT BREATHER NETTING during the veneering proces ?

[leslierogers]

Nice job, thank you for sharing your knowledge

[VijayaBjoshi]

Thank you for sharing even the failed attempt. Honesty appreciated - I would suggest and I know it will work 1. First fold the two layers of open end of bag and staple the it.
2. Now secure secure the strip to the table with two way tape to avoid curling and apply the glue to the tape
or the stapled bigger piece as you wish but the former would be better as glue will not stick to your fingers .
3. Apply the glue to half of the tape
4. Then attach the stapled bag to the tape with firm pressure.
5. Then apply the glue to the bag side upper surface and fold over the tape using roller
6. Attaching strip would be easier with no glue on it.
7. and you will be in control not the tape, it to curl. If timing is an issue then apply the glue as you slide the [attach- English my third language] the slip like attaching piping while sewing the garment.
Good luck

I myself will try this and might post video But I think you are better at presenting
Look forward to your success in making the bag if not already doe so.
Now I am off to Joe's site
and also I think 2 Ways to Make Sealing Machine video by Juggad is very interesting to make own bag though it is on small bags.

[vinceamato]

Thanks for all your instructional videos!  I also am cheap and wanted to make my own vacuum bag. I know you do your research and was wondering what you thought about using vacuum bag sealing tape (ex. Jamestown Dist.) to seal a bag and leaks? Also shown is a polyester mat as a vacuum bleeder. A roll of tape is $15.
What I thought was a vinyl (flooring) covered assembly table and tape down the vinyl bag material to the top to form a vacuum bag. This could form a large or small bag. Or use it on the seams to form a bag.

I think the film and sealant tape used for fiberglass injection molding would work very well for this application.  Instructions for this can be seen at the fibre glast website.

Don't let 'em get you down. My experience 15 or 20 years ago was full of disappointments. I'll go back to vinyl next and click to joewoodworker.com right now. Thank you for posting what you've learned.

[desalvo]

can u heat weld it instead (heat gun..)  vinyl..??,  and how do u seal the open end after putting in your wood panel, ..??  

[joselacera]

thank u for this video can u please tell me where to buy the valves

Can you use a vac and bag to infuse wood with a stabilizer? vac chamber is to small for something i need to infuse.
