[NSRCA-discussion] Carbon fiber shortage

Wed Jul 19 15:48:14 AKDT 2006

Orland has lubed his twice now with it and it has still had a sheen to the
gears upon opening—but no grease to be found.  I only have about twenty
flights on mine in the Temptation—but had eighty on it the first round when
I didn’t know any better and had some bad info on maint. of these critters.
I had about 30 flights on the Impact and needed to do some trim mods on
it—so I greased it then but haven’t flown it again as I only have 2 sets of
working batteries and don’t want to run them in 100 degree plus heat if I
don’t have to as they don’t cool down enough to get them re-charged in a
timely manner.  I’m working on a couple more sets—but not sure just where
they are coming from yet
  The grease really quieted the gear sets down in
both Orland’s and my airplanes—but I’m afraid mine may have gone a little
too long and is a tiny bit loose and a smidge louder.  I’ll be interested to
see how the Impact sounds now since it wasn’t abused (as much).  I happened
to try some of this stuff on sliding bolt locks and door latches and it
works well (creates a tough film I think)—It’ll be interesting to see how it
does in the cold.  According to the directions, you only use about as much
as your little finger nail—a tube ought to be good for about a thousand
relubes.

The process only took about an hour and 15 mins. the first time and about a
half hour the second.  I screwed up the first time and un-did the rear
mount—forgetting the motor would just slide out after un-bolting the front
four—duh.  If you don’t have a strap wrench, you can take a hose clamp,
clamp it on the gear box portion, tighten, then clamp the screw portion of
the clamp in a vise—then use a grippy rubber jar opener helper (don’t let
the spousal unit know what you are up to) on the motor to un-screw after
loosening the two set screws that may or may not be tight.  Some evidently
were Loctited more than others.  The first one I was able to just twist it
and it unscrewed by hand—the second was a bit more difficult--I needed help
and didn’t have a strap wrench handy.

Getting back to R/C, did you get any reports on the Shell lube in the Hacker
C 50s?  I sent some to Dave Snow and just looking at it, he thought it was
on the thick side, but that maybe good.  I'm at 44 flights so it is about
that time.

Drat-the Yukon spends most of its time at around 712' MSL (10" AGL).  Won't
do us much good....

There was a program on Nova or one of those science things that talked about
it.  Some Brit did a study for Israel back in the early 50s to measure the
heat load so they could design their irrigation system.  For some reason he
went back and did it again within the last few years.  He found that there
was something like 20% less heat from the sun but no one was interested
because everyone knows we have global warming.  Then some guys in Australia
who measure the rate of evaporization got together with him and their data
correlated very well.  They then showed pictures from space of the contrails
up and down the Western states and explained how the water droplets formed
on the jet soot and reflected the sunlight.  A very interesting program.
Sounds like we need more high altitude pollution to counter global warming.

Actually, I do remember reading about the effects of high-altitude jet
exhaust in an article about 4 years ago. Seems that after 9-11, someone did
a study. It was due to an extremely rare moment in history, when no
airplanes were allowed to fly, at least in the Con US. According the the
report I read, the effect was measureable.

A thought on a hot day-supposed to be 104 F today in KC.  Has anyone done a
study on how much fuel gets injected into the upper atmosphere by jets?   I
know there are PIPELINE(S!) of the stuff going from the Gulf coast to the
East coast and elsewhere.  You certainly hear about pollution from any kind
of ground vehicle-but absolutely nuthin' about airline, GA, and military
transport.  It would seem that a little spread out in the upper atmosphere
would have a great deal more effect than a lot spread closer to the ground.
I AM feeling a little guilty driving a hog, however.  I'm thinking 'sacred
cow' information suppression-we might have to truly get our act together on
high-speed mass transit.

Off soapbox--wish I was at the NATS,

Just because those "Road Warrior" movies were film in Australia does not
mean they are true!  Besides, I love $3/gallon gasoline.

1. People use less
2. Alternatives become cost effective
3. Ethanol will replace Gasoline and we can save oil to make CF!

Hey Gray,

I Think the A380 cant get to Oz fast enough. I think on these long haul
flight routes it will be a good thing-HOWEVER-personally I'm not too keen to
get on anything made by Airbus. I shudder every time I have to get on
one.They seem to have a habit of falling out of the sky. Isn't there some
kind of joke amongst Airbus pilots? Something along the lines of-'why did it
do that?'

I believe Australia is also involved with the JSF.  Down here, there has
been some political debate over it lately, along the lines of, overpriced,
behind schedule and yesterdays technology.....all good stuff really, cause
when we run out of oil shortly, no one will be able to afford air travel or
fill their car with gasoline. I doubt the JSF will be much good to anyone
either sitting on the tarmac ( unless its powered by anti-matter and
Dilithium crystals <VBG>)

I think our dependence on the middle east because of its oil will affect us
all more than we think. Isn't carbon fibre manufacture dependant on oil as
well? How do they heat those furnaces?

Luckily most of my modelling endeavours will remain  in mostly balsa, and
maybe the remaining rolls of carbon in my workshop may become  worthwhile
'stock' <G>  AND even better, maybe my unbuilt PL kits will appreciate in
'value' after all........hehehehehehehe...I wished ..sigh.
