After my How-to video on cutting surfaces, a lot of you asked for a video on how to do the vacuum bag process. This is the video :)

Great video show, greetings from Indonesia 😀
Love it! I have bagged som dlg wings myself so satisfying!
Beautifull video, great visual content to learn to make this beautifull wings.
Can see that there are a lot of hours and trys behind this clean and beauty work.
I'm building a 4m astir scale glider, i have now the foam cores and going to fiberglassing this wings with the best of my😅😅.
Thank you to teach us a lot with this beautifull video!
Briiliant Alex, thanks for sharing.
I like the details you've included. The headcam is great IMHO, the audio is spot-on. Your apprentice is switched-on too.
That perforator tool is something I reckon I'll use. I'm building a 6M ASH 31.
Thanks for the feedback. Wishing you great success with the ASH 😁
Informative. .... now if I could just stop these seizures lol
Apologies for those 😅
Can you do a video about your DIY refrigerator pump setup? It looks very cool!
I can try do that. The controller was done by a friend of mine
Awesome how-to video 👍
As a fellow kiwi I'm wondering where you buy the high density foam from for the cores?
I can only find beaded polystyrene in the hardware/building stores.
Cheers
I get it from specialty insulation places. Composite-nz etc
How did the wings come out? I would love to see the finish product. Great video thanks
Thanks! Will add the finished product in future videos
Hi Alex. I am making a wing in two halves like this with a shear web spar caps. How should I join the wings? Is it worth the trouble of finding a way to make the spar go across both?
Send me an email to alex.james.hewson(at)gmail.com and We can brainstorm a good solution together 🙂
Mucha resina, se puede hacer con la tercera parte.
There is a tool make by Mono Kote to prep the wood called the wood picker works great
Except it isn’t made anymore. Im now using a derma roller
Which resin did you use, and were the cores cut using a cnc hot wire cutter?
I used ADR 246TG resin and ADH28 hardener. Yep, cores were cut on a CNC hotwire.
What is the thickness of the mylar and where did you purchase it? Thank you.
It was 0.014” thick and from Electropar here in NZ
Alex you gotta switch to a 50hz based frame rate to prevent flicker on your headcam.
Did that, changed the frame rate settings, tried an ND filter and some other setting recommended on the net. No change unfortunately
It’s called rolling shutter. Can be dealt with in post if the camera isn’t smart enough to sync. Otherwise nice vid! Thank you.
Hey Alex,
Doesn’t the Resin cause the foam ?
Hi, I didn’t follow the question sorry
@@AJHewson1 Doesn’t the Resin cause the foam to melt due to the over heating during cure time ? ✌️
Sorry about that, must have said it in my head without typing it.
@@MohamedHetta nope, it doesn’t exotherm with a slow hardener. Also as soon as you use it over a large area, it reduces the chance of exotherm. If you leave a cup of resin, because it has a large volume in one spot, it will exotherm
Awesome ! .. One more question, is there any rule that constraints the amount Resin one should use ? like a Resin to Fiber ratio ?
@@MohamedHetta there is somewhere, but I go by look and feel
What weight cf did u use?
This had 200gsm biaxial and 250gsm uni
PHIl BARNES mode??
Have his bagging series on DVD somewhere. Learnt a lot from him
