I've use this before on breaking loose robotic components - it works great.
But did you know you can add equal amounts of deodorized kerosene and
aliphatic mineral spirits (Stoddard Solvent) to the ATF/Acetone mix to make
a cheap but highly effective firearm bore cleaner? Make sure you store this
in a metal or chemical resistant container (the plastic gas cans work great)
or you will have first hand experience with a Hazmat spill.

For Al: Thank you for touching our lives.
1 The LORD is my shepherd, I shall not be in want. 2 He makes me lie down in
green pastures, he leads me beside quiet waters, 3 he restores my soul. He
guides me in paths of righteousness for his name's sake. 4 Even though I
walk through the valley of the shadow of death, I will fear no evil, for you
are with me; your rod and your staff, they comfort me. 5 You prepare a table
before me in the presence of my enemies. You anoint my head with oil; my cup
overflows. 6 Surely goodness and love will follow me all the days of my
life, and I will dwell in the house of the LORD forever.
Psalms 23
Rest in peace AL N7ADU

For stainless, it is best to start with NoAlOx on all
your stainless hardware to prevent the stainless
from galling and seizing.
Over time the stainless will be easier to "unbolt."

Saw this post on the 599 DX Association Reflector - might come in hand for
those rusty tower bolts.
BTW, this is Lew King, W5LEW, K5GIT's brother-in-law, who was hanging out
some at McDonald's with the HCARC Wednesday morning gang this past Fall.
I'm over in Mississippi in the motorhome for the winter and will be
WorKamping again this summer in Colorado. However, I'll be back in
Kerrville briefly in late April and will try to pop in at McDonald's to
catch up on you guys. We were also in that 16 mile wide monster hail-storm
here in the Jackson, MS area that made the national news last week - had
baseball and softball size hail here in my RV park! Damaged both motorhome
and van - the van got the worst damage with a shattered windshield - it's
estimated that 10,000 homes and vehicles were damaged in the Jackson area.

"Machinist's Workshop" recently published information on various
penetrating
oils. The magazine reports they tested these products for "break out
torque"
on rusted nuts and bolts. A subjective test was made of popular penetrating
oils, with the unit of merit being the torque required to remove the nut
from a "scientifically rusted" bolt.
Average torque load to loosen nut:
No Oil used ........................516 foot pounds
WD-40 ..................... ........238 foot pounds
PB Blaster .........................214 foot pounds
Liquid Wrench ......................127 foot pounds
Kano Kroil .........................106 foot pounds
ATF/Acetone mix...................... 53 foot pounds
The ATF/Acetone mix is a "home brew" mix of 50/50 automatic transmission
fluid and acetone. Note this "home brew" released bolts better than any
commercial product in this one particular test.
Our local machinist group mixed up a batch, and we all now use it with
equally good results. Note also that Liquid Wrench is almost as good as
Kroil for 20% of the price.
ATF/Acetone mix is best, but you can also use ATF and lacquer thinner in a
50/50 mix. ATF = Any type of Automatic Transmission Fluid. This was in one
of the Military Vehicle Club newsletters >>

Neat Story I never heard.
Skip W5GAI
------------
It all started with a skin flick.
In 1933, a beautiful, young Austrian woman took off her clothes for a
movie director. She ran through the woods, naked. She swam in a lake,
naked. Pushing well beyond the social norms of the period.
The most popular movie in 1933 was King Kong. But everyone in Hollywood
was talking about that scandalous movie with the gorgeous, young
Austrian woman.
Louis B. Mayer, of the giant studio MGM, said she was the most beautiful
woman in the world. The film was banned practically everywhere, which of
course made it even more popular and valuable. Mussolini reportedly
refused to sell his copy at any price.
The star of the film, called Ecstasy, was Hedwig Kiesler. She said the
secret of her beauty was "to stand there and look stupid." In reality,
Kiesler was anything but stupid. She was a genius. She'd grown up as the
only child of a prominent Jewish banker. She was a math prodigy. She
excelled at science. As she grew older, she became ruthless, using all
the power her body and mind gave her.
Between the sexual roles she played, her tremendous beauty, and the
power of her intellect, Kiesler would confound the men in her life,
including her six husbands, two of the most ruthless dictators of the
20th century, and one of the greatest movie producers in history.
Her beauty made her rich for a time. She is said to have made - and
spent - $30 million in her life. But her greatest accomplishment
resulted from her intellect, and her invention continues to shape the
world we live in today.
You see, this young Austrian starlet would take one of the most valuable
technologies ever developed right from under Hitler's nose. After
fleeing to America , she not only became a major Hollywood star, her
name sits on one of the most important patents ever granted by the U.S.
Patent Office.
Today, when you use your cell phone or, over the next few years, as you
experience super-fast wireless Internet access (via something called
"long-term evolution" or "LTE" technology), you'll be using an extension
of the technology a 20- year-old actress first conceived while sitting
at dinner with Hitler.
At the time she made Ecstasy, Kiesler was married to one of the richest
men in Austria . Friedrich Mandl was Austria 's leading arms maker. His
firm would become a key supplier to the Nazis.
Mandl used his beautiful young wife as a showpiece at important business
dinners with representatives of the Austrian, Italian, and German
fascist forces. One of Mandl's favorite topics at these gatherings -
which included meals with Hitler and Mussolini - was the technology
surrounding radio-controlled missiles and torpedoes. Wireless weapons
offered far greater ranges than the wire-controlled alternatives that
prevailed at the time.
Kiesler sat through these dinners "looking stupid," while absorbing
everything she heard.
As a Jew, Kiesler hated the Nazis. She abhorred her husband's business
ambitions. Mandl responded to his willful wife by imprisoning her in his
castle, Schloss Schwarzenau. In 1937, she managed to escape. She drugged
her maid, snuck out of the castle wearing the maid's clothes, and sold
her jewelry to finance a trip to London .
(She got out just in time. In 1938, Germany annexed Austria . The Nazis
seized Mandl's factory. He was half Jewish. Mandl fled to Brazil .
Later, he became an adviser to Argentina 's iconic populist president,
Juan Peron.)
In London , Kiesler arranged a meeting with Louis B. Mayer. She signed a
long-term contract with him, becoming one of MGM's biggest stars. She
appeared in more than 20 films. She was a co-star to Clark Gable, Judy
Garland, and even Bob Hope. Each of her first seven MGM movies was a
blockbuster.
But Kiesler cared far more about fighting the Nazis than about making
movies. At the height of her fame, in 1942, she developed a new kind of
communications system, optimized for sending coded messages that
couldn't be "jammed." She was building a system that would allow
torpedoes and guided bombs to always reach their targets. She was
building a system to kill Nazis.
By the 1940s, both the Nazis and the Allied forces were using the kind
of single- frequency radio-controlled technology Kiesler's ex-husband
had been peddling. The drawback of this technology was that the enemy
could find the appropriate frequency and "jam" or intercept the signal,
thereby interfering with the missile's intended path.
Kiesler's key innovation was to "change the channel." It was a way of
encoding a message across a broad area of the wireless spectrum. If one
part of the spectrum was jammed, the message would still get through on
one of the other frequencies being used. The problem was, she could not
figure out how to synchronize the frequency changes on both the receiver
and the transmitter. To solve the problem, she turned to perhaps the
world's first techno-musician, George Anthiel.
Anthiel was an acquaintance of Kiesler who achieved some notoriety for
creating intricate musical compositions. He synchronized his melodies
across twelve player pianos, producing stereophonic sounds no one had
ever heard before. Kiesler incorporated Anthiel's technology for
synchronizing his player pianos. Then, she was able to synchronize the
frequency changes between a weapon's receiver and its transmitter.
On August 11, 1942, U.S. Patent No. 2,292,387 was granted to Antheil and
"Hedy Kiesler Markey," which was Kiesler's married name at the time.
Most of you won't recognize the name Kiesler. And no one would remember
the name Hedy Markey. But it's a fair bet than anyone reading this
newsletter of a certain age will remember one of the great beauties of
Hollywood's golden age ~ Hedy Lamarr. That's the name Louis B. Mayer
gave to his prize actress. That's the name his movie company made
famous.
Meanwhile, almost no one knows Hedwig Kiesler - aka Hedy Lamarr - was
one of the great pioneers of wireless communications. Her technology was
developed by the U.S. Navy, which has used it ever since.
You're probably using Lamarr's technology, too. Her patent sits at the
foundation of "spread spectrum technology," which you use every day when
you log on to a wi- fi network or make calls with your Bluetooth-enabled
phone. It lies at the heart of the massive investments being made right
now in so-called fourth-generation "LTE" wireless technology. This next
generation of cell phones and cell towers will provide tremendous
increases to wireless network speed and quality, by spreading wireless
signals across the entire available spectrum. This kind of encoding is
only possible using the kind of frequency switching that Hedwig Kiesler
invented.

All,
I have worked with 1/2" 316 stainless bolts for many years doing electrical
projects.
It does not hurt to lubricate the bolts, however, the real problem with
galling on stainless
bolts is caused by tighting the nuts beyond the specified limit and not lack
of lubrication.
