Has anyone used Aeropoxy 6228 exclusively for their plane? For example, no
Araldite 420 at all?
If so, how has it turned out, for things such as the tailplane torque tube
bushings?
Thanks in advance,
Greg Fuchs, A050

| Subject: | Re: Aeropoxy 6228 ~ NEV? |
I have been most interested in this product. The Aeropoxy rep at Sun N Fun
had told me the it was under testing by Europa as a replacement adhesive a few
years back.
I talked with Andy a year later, at Sun n Fun inquiring about the testing. He
replied that the product did not hold up to his expectations. Therefore it
was never "approved".
I most certainly would like to know more about the testing and what issues
were found. The 6228 has cost and accessibility benefits.
Perhaps Nev could fill us in on the subject?

Can someone direct me to a company in the US that makes a good canopy cover
for the Europa?
I know years ago there was a lot talk about a hot weather cover and a
standard "hanger" cover. What is the real story and who makes the best for
full on sunny outdoor weather. I talked a rep from Bruce's custom covers at
OSH last year but did not take the plunge. Fly-in season is starting and I
would like to have a cover to keep the dust and heat out.

Hi Brian et all,
The Aeropoxy adhesive is NOT suitable as a replacement for Redux / Araldite
420 in use on a Europa.
Tests I carried out way back when , back to back, with Aeropoxy and 420
showed the Aeropoxy to be far too brittle.
Lap joint test samples were made useing the pre preg laminates as in the
fuselage / wing skins, same materials / same sizes / same surface preparation
/
same cure cycle / with both adhesives. Did 10 of each from memory?
Didn't need to get them scientifically strain tested [ by Slingsby, which is
what we had done with various lay up resins] a simple blow with a hammer on
one end of the tab , with the other end clamped in a vice showed that the
Aeropoxy bonded ones let go every time, whereas the 420 bonded ones would take
one hell of a beating before eventually the pre preg would fail.[ Same hammer
! ]
The make up of the 420 includes rubber granules, so there is a fair amount
of '' give '' in the bond.
This is allways a good test to check if the 420 has '' time lifed ''. [ in
spite of the very conservative expiry date set by the manufacturer ] If the
bond fails, bin it, if the glass fails, it is still good.
I also tested a couple of other adhesives [ at different times ] against the
420, similar results.
If there had been a suitable replacement to 420, it would have been used in
the U.S.A. as we had a lot of hassle getting the 420 shipped over [ Dangerous
Goods and all that !]
Don't experiment and risk your life, just to save a few bucks ?
Cheers,
Nev.

| Subject: | Filling, what works for us |
Figured would mention what works for us filling:
Washing control surfaces in shower with "HOT" water and plain green
Palmolive dish washing detergent
I sewed up a big sausage (~ 10 feet long and 4 feet in diameter) out of
clear vinyl ( www.mcmaster.com ) with a zipper, a muffin fan and 2 thin
wall aluminium tubes to hold it in shape when zipper opened. Garbage
picked electric heater 1 with fan and oscillates and 1 stationary, I
mutilated thermostats and thermal fuses. We drape thin bubble wrap over
sausage. Packs up very small when not in use, can hold 140F but we cooked
a little longer at 135F
Once post cured, went after with stiff scrub brush and post cured till dry
and only handled with gloves
Scuff sanded with 80 grit, then vacuum and blow off with oiless compressor
Painted and wet out with Aeropoxy and 60 minute hardener, once it begins
to thicken squeegee off, and don't apply Expan-cel until it is real
sticky.
If you use a blade too wide, or you don't wait for wet out coat to get
sticky the Expan-cel mix will roll/lift off. I have seen pics of folk who
fill with Expan-cel and it has a complete gloss on it. Hard to sand and
heavier than it needs to be.
We mixed up 6oz of resin (not including hardener) in a 8 oz cup, and would
pour into a second cup with fresh stick (double cup). Then would leave
some in the 8 oz cup and put a little over 2 oz into three 12 oz cups.
Using a sugar scoop to add Expan-cel and get things very very dry. By
scraping contents of the cup onto the walls of the cup, can squeegee very
hard and get out most trapped air and mixture is thin enough to not kick
off too soon. It is pretty amazing at just how well this dry mixture
sticks, as long as you are going onto sticky resin base coat.
We found applying with a thin very flexible putty knife works well, bout
1.25 inches wide. When we tried using a wider or stiffer knife, you need
to wet out much more to get it to stick proper. This technique will not
allow you to put on like a master spackler and get an immaculate finish,
but you can get stuck very very dry mix with minimal bubbles. It sands
easy enough if you apply a very dry mix. There is not a hint of sheen
anywhere in the cup, and if only a few drops less epoxy used, the mix
rolls up and crumbles. After a few cups, you can add Expan-cel and get to
the roll up and crumbles stage, then get it just wet enough by scraping
the corners of the cup that have a slight gloss. You can cut rounded
mixing sticks to have a 90 degree edge to help get into corners.
Once cured enough to transport in car, into oven.
Works for us.
