Hi Bob and all,
As a European I'm accustomed to see US citizens use Fahrenheit for CHT,
oil temp etc.
But in an original P51 manual, I'm puzzled to find temps in Celsius.
How come the Celsius were fashionable in the '40s when only Anglo-Saxons
were flying US airplanes, and now they have reverted to Fahrenheit ?
Thanks,

Great question Giles...
Here is another nail in the coffin of the folks who moan "I love American
non-standard measurement".
Last summer I was repairing my fathers 1951 John Deere B farm tractor.
What's more American than John Deere ?.
The tattered owners manual calls for 18mm Champion spark plugs.
What happened to our good sense ?

Gilles,
When I was in the fourth grade I think, about 1962, we began learning the
metric system. I was really excited to be growing up at a time when this
change would happen. It was a time of
innovation and rapid progress in the sciences and industry in this country.
The cold war was on and we were still ducking under our desks for those
"nuclear" drills. Jets were dogfighting over Korea, ICBM's were roaring into
orbit overhead, we were about to put a man on the moon and NO-ONE doubted
our ability to do so. The USA was instilled with a pride and confidence born
of success and
progress. This "new" metric system, I thought, was just another sign of our
advancement as a Civilization.
Even a prodigy, er, uh, child such as myself could see the obvious
superiority of the metric system. No more ciphering fractions of inches and
inconvenient conversion factors such as 12 inches per foot and 3 feet per
yard and 5,280 feet per mile and such. Yuk. What a crappy system. Now, all
would be simple and sweet. The meter. 100cm per meter! Just move the decimal
point! Same number. No ciphering. 1000 meters per kilometer. Just move the
decimal point. Same number. Speed of light 300,000 K/s, Frequency 100,000
Hz, wavelength = 3 meters, 1/4 wave antenna 3/4 meters or 75cm. Just get the
tape, mark 75 and cut. Easy! Water freezes at 0 degrees C and boils at 100.
A really cool and useful standard.
So, we started the switch. But then something curious happened. We didn't
actually DO it! Who knows why. Tradition. Laziness. Fear. I don't know. What
I do know is this. We now have the worst of both worlds. Every American now
has to have TWO sets of tools! Every car or piece of equipment seems to be
stuck in between metric and imperial or SAE as we call it on this side of
the pond. We're stuck in the 60's!
HEEEEEEEEEEEEELLLLLLLLLLLPPPPPPPPPPPPPPPP!

The answer to this one is pretty simple. Bosch was the first maker of spark
plugs and set the standard. you could probably go back to a 1921 owner's
manual and find the same reference. So far as I know, spark plugs are all
metric thread and always have been.

Good Morning Richard,
How very true, but, fortunately, the ones we have been
using for aviation here in our crazy mixed up country
have had a hex drive portion that was made to fit our
good old fashioned foot/inch measurement system.
I'd say odds are that old John Deere/Champion plug
used a non metric wrench to aid it's extraction.
Have you ever noted that aircraft mechanics world wide
seem to have standardized on our system as well?
Will wonders never cease?
Happy Skies,
Old Bob

No. You'd have to do a load analysis to see how
often and under what conditions that the alternator
gets loaded. It would be interesting to have a
real loadmeter on the alternator to simply observe
it's daily duties.
My last two vans had 90+ amp machines on them but
both had rear a/c and heater blowers. But those blowers
seldom run more than 12 amps or so, so that leaves
a whole lot of juice to run everything else.
It might be something so simple as the "Cessna philosophy"
on equipment sizing. At some point in time, all the SE
aircraft from 150 to 210 got the same 60A, 28v alternator.
There were only two battery sizes offered. This singular
focus on a smaller selection of parts reduced inventory
at the warehouse, factory and dealerships.

Obviously, a 'connection' will be made and the terminal
is not at-risk for falling off. But keep in mind that
terminal application is tailored around the idea of
achieving gas-tight connections in the mating parts.
Gas-tight connections require optimized force being
exerted over a terminal area. The peak forces within
a bolted stack up of terminals happens right around the
stud . . . if the hole in the terminal is oversized, then
we've compromised design goals for the product.
Are you likely to experience any difficulties for the
compromise? No. But it IS a compromise and not the best
we know how to do.

Why do some folks call them "pancakes", others "flapjacks", while
still others speak of "griddlecakes". You're not witnessing a
reversion but simply an illustration of how various products
and technologies reflect their roots.
Our aviation services have mixed and matched scales and
nomenclatures for the same or similar information since
day-one. Temperatures at altitude have always been offered
in C while ground temps were until a few years ago offered
in F. Directions on the ground were in magnetic while winds
aloft were in true. Some folks like to offer pressures in
inches-Hg while others gravitated to millibars or even mm-Hg.
ATP category aircraft shared a lot of engineering and
operating philosophies with military aircraft and tended
to be more formal in the descriptions of performance while
single engine aircraft that targeted John Q Public were more
likely to speak in a language common to folks who drove
cars and trucks and got their weather from the radio.
Yes, there was a grand push to avoid confusion, make teaching
easier, reduce errors, and perhaps even foster a sense
of "oneness with the world" by adopting the metric system.
And to be sure, there are some obvious advantages. But doing
so requires a singleness of purpose for a majority of
a population for several generations in order to flush out
the old and replace with the new.
In the mean time you have cost of creation and ownership
issues for the folks who have to purchase, stock and
maintain the hardware. I still get a sense of !#$!@ when
I have to essentially double the numbers of tools I
own in order to perform basic maintenance on products
I own.
Politicians and preachers have dreamed of world wide
oneness for centuries. Some have attempted to force
their vision on humankind. In the final analysis,
any successful transition will be driven by
folks who deliver the most compelling products. As
our markets experience the forces of world-wide participants,
it will be the systems of measurement favored by the
most competitive suppliers that will prevail. If a
third world society could rise up over the next couple
of generations and provide us with a flow of products
that rivaled the rest of the world, it wouldn't matter
if they used metric, fractional or even some totally new
system of measurement. We'd all go out and buy the
tools that fit those products, grumbling all the way
to the store driving the car that addressed our
perceptions of best value.
The smooth transition to oneness is not by decree or
even obvious logic. It's the whim of suppliers
and the acceptance of those supplier's goods and
services by a customer who perceives value in
the goods and services. If a huge starship landed
tomorrow and loaded a compelling array of
merchandise into Walmart's distribution pipes,
it's a certainty that very few individuals would
refuse to purchase those products because it takes
yet another set of tools to maintain them or the
temperature gage needed some translation.
In the mean time, we can look forward to more
of the same. It's less stressful to chalk it up to
"diversity and the richness of melding cultures"
than to gunch about it. Now, were did I put that
T9 wrench?

| Subject: | Antennaes and primer |
I have all my antennas..com, nav, and 2 gps antennas under fiberglass. The GPS
antennas are just forward of the wind screen, theNav antenna is in the belly
and the com in the leading edge of the vert stabilizer.
The only difference between my plane and the prototype is the primer and my control
surfaces (elevator, rudder, ailerons, and flaps) are carbon fiber not fiberglass.
The Prototype used PPG K36 with K201 hardener, I used Dupont Nason 421-19 with
483-87 hardener.
The MDSS lists aluminum, iron sulfate and carbon black in unknown quantities in
the DuPont product. These are not listed in th MDSS for the PPG product.
I find I transmit and recieve normally on frequencies below 125.00 but TX and RX
is very weak above this. My Nav reception is exceedingly weak across the board
and both GPSs take up to 10 minutyes to lock and then only see 4 sats.
The com nav bench checks fine and when I recieved the BMA Efiss and tested them
in the car they locked on in seconds.
Can the stuff in the primer cause this? If so how large an area around the antennas
do I need to sand.

So explain how virtually every American car post WWII used 14mm plugs,
until they went to those tiny ones. Perhaps 14mm and 18mm just happen to
be equal to an English thread size. Especially since they both require
an English unit plug socket, either 13/16 or 7/8.
