Molding/Bagging

Hello,

Can anyone recommend any websites, books, or videos on fuse mold building or wing mold/bagging.

Thanks

Bob

Phil Barns gives you all you ever wanted to know about vacuum bagging composite, foam cored wings in excruciating detail on a two DVD set for $55 plus $6 shipping and handling. You can order Vacuum Bagging Made Easy from:

Mr. William Haymaker
107 Schofield Drive
East Berlin, PA 17316

Soar Tech 10 has an illustrated article of about 40 pages on composite construction including molds for hollow molded wings. It was available from the publishers of Flying Models Magazine at one time. The original publisher was Herk Stokely, 1504 North Horseshoe Circle, Virginia Beach, Virginia 23451.

Re: Molding/Bagging

I've read a few how-to's, but not sure what happens to the mylar - does this
get removed after the bagging, then you end up finishing the fibre glass
directly?

Cheers,
Andy.

Yes, the mylar is removed after bagging. Normally you wax and paint the
mylars, lay up the glass directly on the mylars, then insert the foam
core into the mylars (like a taco) and vacuum bag. When you pull it out
of the bag, remove the mylars and you will have a nicely finished
surface on your wing.

Re: Molding/Bagging

aha - I get it.
Would love to have a bash at this (space permitting)...anyone have any nice
sources for the vacuum pumps though? (preferably in the UK, but anyone who
will ship international is fine too)
Thanks,
Andy.

A real vacuum pump (piston pump with electric motor) will set you back
a minimum of $200 here in the USA. I assume you could get one for
200 quid somewhere, possibly from a supplier of air conditioning
service tools. There are venturi devices that run on compressed
air for 10 to 50 dollars, if you have an air compressor they would
suffice for occasional use. Another cheap option is to salvage the
compressor and motor from a refrigerator or small air conditioner,
expect them to have a shortened lifespan when run on air instead
of oil/refrigerant mix.

I bought an old refrigerator motor for $US30. It died after a few
test layups and you can't fix a dead refrigerator motor because the
case is welded shut. So, I spent the last couple of weeks on Ebay
doing a search on "Gast." I found a Gast vacuum pump for $20. It's
spec'd to pull 25mmHG, more than enough vacuum for bagging.

I found the average pump price on Ebay for a Gast model DOAxxxx or
MOAxxx to vary widely from $US30 to $US130. These models are used
for airbrushing and lab work and pull around 22mmHG, depending on
model. You can find the specs at www.gastmfg.com. If you do look on
Ebay, doublecheck to make sure the model you're looking at actually
provides vacuum. Most Gast pumps seem to be able to used both for
vacuum and compressed air, but some don't.

Good luck!

Vacuum Bagging Video Information

Thanks again for the mention Ollie,


Phil Barnes is well know in sailplane circles. He has been manufacturing
wings for many, many years. First working with Frank Weston making Magics
and Merlins. For many years now, he has been making most of the bagged wings
and tails for Northeast Sailplane Products thermal and slope kits. Last year
he started producing wings for Polecat Aeroplane Works popular line of DLG
gliders. He also sells the Tom Kiesling designed Mantis Unlimited TD kits
directly. If you fly sailplanes, chances are you have flown wings made by
Phil at one time or another.

This 4 1/2 hour instructional video takes you step by step, in great detail, through the processes of making vacuum bagged composite wings and tails starting
from raw foam right through to finished parts.

This is a 2 DVD set, packed full of invaluable information, that will
ensure the novice good results as well as give the seasoned builder new
insight into producing top quality wings and tails. If you bag your own
wings, or want to get started, this is a one of a kind, must have, video.

You can download a couple of Video clips and read testimonials at;
