| Subject: | stall warner mod 61A - drawing error |
--> Europa-List message posted by: Rowland & Wilma Carson <rowil@clara.net>
I just collected my Mod 61A from Kirkbymoorside last week. Yesterday
I stuck a copy of the wing LE template onto card and offered it up to
the wing. Alas! it didn't match the profile. Then I noticed that the
template was marked BL52.25, whereas the instructions referred to
BL102. Sure enough, sliding the template towards the root gave a good
fit. I called the factory and Roger fax'd me a copy of the template
from the Mod 61B instructions, which correctly shows BL102.
So, if you have received Mod 61A with a template marked anything
other than BL102, you should get in touch with the factory for the
correct drawing.
regards
Rowland

Cheers,
I have read the thread regarding the utility of post-curing. A
composite guru in our chapter took a sample of my Aeropoxy lot and sent it
to Stuttgart where they test these things, without post-curing (ie, room
temp). It came back with a Tg of 78.3deg C.

Hi
Does anyone know were i can get hold of a suitable wing tip cover that will fit
over the XS wing tip
A manufacturer and part No would be great.
Cheers

Do Not arcive
Hello R.C. Harrison
I kinda sortta thought of sarcasm, but didn't get it ;-(
Carburation is something i have always been in tune with. You do not need very
much to clog a small orifice. Just a tad of rubber from assembly or a piece of
debris from assembly, or slow but sure "Carb Snot" formation.
Not many from the flock of Europas having gravity win, when pilot does not want
it to.
Nice to know symptoms though.

Not sure which way to take that, but an optimist might say success
within 10% of spec by us amateurs, and well sufficient for the purpose,
is a good thing?
How much time elapsed between lay-up and test, and at what storage temp?
Supposed to make a difference. Otherwise a pessimist would wonder if
them spec sheets are premised upon fresh product, minimum humidity, and
mix accuracy by weight not to exceed the guano of a flea.
Since Aeropoxy apparently performs better at only room temp than others,
even at your tested 78C, their silence on postcure is curious. The
stuff is marketed for airplane homebuilding, and a second-year law
student would be able to lecture these people about relevant disclosure.
Maybe it's because postcure temp of more than marginal benefit for
this product is a bit hot, introducing the risk of botching the job in
ways not conducive to inspection.
Best,
Fred F.

Fred,
How many ways can you take a Tg of 78.3degC? I don't get the 10%
thing, but if it's a range of 20% ("within 10%) the lowest TG would be over
70degC. and the highest over 85.

There was no layup. It was a batch of epoxy.
> Supposed to make a difference. Otherwise a pessimist would wonder if them

Beats me, lieutenant. I didn't look at the spec sheets. Our
expert just mailed(?) the sample to the test centre and got the answer back.
I don't suspect either he nor the centre (if they mixed it) would have check
for flea droppings. Since it is the DIN test centre for the topic, I trust
both to be more accurate than I, and my greatest ratio mix error has not
exceeded 0.5% yet.

The point is.....?

I am no expert and have to take some statements at face value so
have done so in this case, as am aware the Deutsch school of Accuracy beats
my alma mater. A hot marginal benefit is over my head. I guess the makers
have a "Can't-touch-me" clause for guys who build outside the stated limits.
As for inspection...................
Best regards,

Ron,
It won't go quiet. Unless of course the carbs clog up too. If muck gets
this far downstream maybe they will. The 914 does not and cannot have a
restrictor, it's a fuel injection system with a pressure regulator. If
there is any restriction in the return line of a 914 it can overpower the
regulator and cause flooding, I think. Can anyone confirm this?
