Buying stainless steel rod oversize, then turning and grinding, is cheaper (even with the labor) than buying the rod already Turned Ground and Polished (TGP). We're talking small quanitities here, since I work for a small machine shop that does repair work.
A particular piece of 316 stainless came in at ~2.625" Outside Diameter, as drawn (drawn through a die to make it round, not drawn as in on a a piece of paper). It was taken to the Machining area and pre-machined to ~2.500" O.D., then routed to the Polishing Department to polish for chrome plating. We have 0.002" of hard chrome applied to the surface. They call it "two thousandths per side". Try arguing with the plating tech about how a cylindrical object only has one side, the outside. What they mean is that by putting 0.002" onto the outside surface, you add 0.004" to the Outside Diameter (hence "two per side"). So the pre-turned rod had to be ground to 2.5945" to 2.5950" to finish after plating at 2.9990", giving it one thousandth of an inch of slip clearance into the counterbore. I love writing technical junk!
If you're still with me, here's the scenario:
I am looking at the polished-for-plating rod, wrapped in kraft paper and stretch-wrap, on which the grinding technician (We'll call him "Squint") has written in fat black permanent marker: 2.522" .
ME: Hey Squint, didn't this rod get brought to you from Machining?
SQUINT: Yeah. Boss said take four thousandths off it and then get a final measurement.
ME: How can it now be bigger than it was when it was taken out of the lathe?
SQUINT: ...
ME: Um, did you use calipers or micrometers?
SQUINT: I mic'd it.
ME: Can you please unwrap this and do it again?
( Resistance interlude, after which Squint sets the mic but hands it to me. The mic reads 2.4960". )
ME (handing the mic back to Squint): What does that mic read?
SQUINT (gradually extends his hands with the micrometer farther and farther from his face, and walking over to right in front of a 500W job light, while making his eponymous facial expression): Um...
ME: Dude, you need glasses!
SQUINT: No I don't!
ME: You need to have your eyes checked, or at least buy a pair of reading glasses! You can't even read the mics! You're 50 years old! It happens to everybody!
SQUINT: No, they said I don't need glasses.
ME: You had your eyes checked?
SQUINT: Yeah, they said they were fine and I don't need glasses.
ME: You went to the eye doctor, and the eye doctor asked you to read something like I just did, and he said you don't need vision correction?!
SQUINT: Yeah, they said I don't need glasses.
ME: You've been malpracticed, man! Who did you go to? We have Kaiser coverage. You're saying a Kaiser doctor...
SQUINT: Well...
ME: Well? Where did you have you eyes checked?
SQUINT: At the Department of Motor Vehicles when I renewed my license!
ME (NOT out loud): I am so totally blogging this!

Train for a purpose
Some people log running miles as a build-up to a race -- a 5K, a half-marathon, or longer.
When that's the case, the focus is on time over distance, or heart rate training, or hill climbing, depending on the type of event chosen as the goal.
Right now, I have no performance goal.
I want to stay relatively healthy. Happy, too, if I can.
So it is nice to go out and move in the world with the least possible stress. No camera. Not paying any attention to the chrono on the watch. Just trying to move with a modicum of balance and harmony through the world out there.
Mental health running. Soul health running. That's where I'm at as a runner right now.

Now I know how the moon feels
Sunday afternoon was sunny, and it had been a while since the last rain. I decided to run fire trails in the local hills because once on top of the ridge, there would be lots of sunshine! Wheee! Vitamin D!
It was a lovely afternoon. A pair of white-tailed kites and a young harrier were working the west slopes of the hills, hunting for early gopher activity. A happy looking ash-throat flycatcher was stationed on a parks department sign at a trail crossing. The very earliest of the mustard (or is it coming up from last year's?) is starting to bloom.
It was full sunshine at 2:30-ish when I did the out and back miles along the north-south ridge. Heading south, my right side was toasty warm and my left side was freezing. Vice versa on the way back. Being a weather wimp, I admit I had to stop and turn around for a few moments, more than once.
I wonder what kind of weird autonomic nervous system responses your body goes through when one surface of the body is so much warmer than the other. Half my brain: "Happy, happy, sunshine, birdies, flowers, run, run, run..." Other half of my brain: "Stop or die! Turn around! Twirl in place! Aaaurgh!"

Whose life is worthless?
This is a newspaper clipping from Germany, "Völkische Beobachter", Nov. 10, 1938.
Jews Forbidden to Possess Weapons
By Order of SS Reichsführer Himmler
Munich, November 10 [1938]
The SS Reichsführer and German Police Chief has issued the following Order:
Persons who, according to the Nürnberg law, are regarded as Jews, are forbidden to possess any weapon. Violators will be condemned to a concentration camp and imprisoned for a period of up to 20 years.
Never forget how that turned out.
So the question is, who gets to say what kind of life preserver you get to have?

In which we confront reality in a small way
I see stuff like this. Hippie, you just make me tired.
Let's take about fifty yards of cool-ish fabric out into the woods and hang it with coarse jute twine, light a candle on top of some books, and take an art shot. It's that whole environment thing.
Ooh. Pretty.
Let me buy you a clue. This may look romantic. This may look like, "Oh, I just want to spend an afternoon reading meaningful literature surrounded by beauty in a vaguely middle-eastern mode."
The reality is this. Too hot or too cold. Wind. Plants with thorns. Plants that give you a rash. Plants that smell like rancid garlic (foreground).
And more than anything else, bugs. Spiders of many kinds. Midges. Gnats. Flies. Mosquitoes. Depending on your position on the globe, ticks, chiggers, noseeums, deer flies, hornets, wasps, centipedes, scorpions.
Don't say I didn't warn you, hippie.

Ants. Ents.
Dream.
A white featureless and shadowless landscape. A multitude of dark shapes are moving about across a vast plain.
I move closer to the shapes. They are the size of human beings, but shaped rather like the Ents in Lord of the Rings. They are striding about, stomping on something.
Sounds reach me. The hoarse breathing and grunts of the tree creatures, and the sound of their root-feet stomping on something.
I am among them now. They take no notice of me, but go on stomping. They are something like a cut-leaf philodendron and something like a magnolia, with faces at the top of their trunks.
They continue furiously stomping. Stomping on bugs. Ants.
Ants?
One of the Ents executes a quick series of stomps, then whirls and almost runs into me.
I catch his eye as he backpedals. "Hi, 'scuse me. What's going on?"
His eyes widen, and he breathes a short rasping laugh. "Ha! I don't know about you, but this is ONE rubber tree that's had it up to here, and I'M NOT GONNA TAKE IT ANY MORE!"
What makes that little old Ent think he can exterminate all of those ants? Whoops, there goes another...

Along with Col. Jackson
We call it the War of 1812.
The Johnny Horton song says,
But it was on this day, 8 January 1815, that the Battle of New Orleans was joined. And Jackson was Major General at the time. Details, details.
I think we had the Royal Guardsmen album when I was younger, the one with "Snoopy vs. the Red Baron" on it. "Long Playing"! Monaural. We played it over and over on a phonograph with a heavy tone arm. Ah, the history brings back the history.
The Johnny Horton song says,
In eighteen fourteen we took a little trip
Along with Colonel Jackson down the mighty Mississip'.
We took a little bacon and we took a little beans,
And we fought the bloody British near the town of New Orleans.

We fired our guns but the British kept a comin'.
There wasn't nigh as many as there was a while ago.
We fired once more and they began a runnin',
Down the Mississippi to the Gulf of Mexico.

I saw the light, yes...
7 January is a red letter day in my personal cosmo-chronological calendar. Today is the day (where I live) when not only is the time of sunset later than it was yesterday, but the time of sunrise is also earlier than it was yesterday. (Confused yet?)
The Days of Darkness are officially ended!
Bright beautiful days are all lined up out there ready to enjoy in 2013! Now there is real reason for hope.

The Three-fold Manifestation
Epiphany.
The root of the word is the word for light. Epiphaino, in Greek. The same root shows up in words like photograph and phenomenon.
An epiphany is a manifestation and an illumination.
The traditional understanding of the feast of Epiphany is a triple manifestation of the person of Jesus in the gospels: at the nativity, at the baptism in the Jordan, and at the wedding at Cana. I tend to think of it only as Three Kings Day because it closely follows Christmas, but the Roman Catholic readings for the feast take turns going through the stories of the three manifestations through the three year cycle of readings. At the nativity, the child Jesus is made manifest to the shepherds and the magi. When he submits to the baptism of John, Jesus is made manifest as he starts his active teaching ministry. At the wedding at Cana, Jesus is made manifest through the miracle of the water turned to wine -- "This, the first of his signs, Jesus did at Cana in Galilee, and manifested his glory." (John 2:11, ESV)
"Three mysteries mark this holy day: today the star leads the Magi to the infant Christ: today water is changed into wine for the wedding feast: today Christ wills to be baptized by John in the river Jordan to bring us salvation."
(Antiphon for the Magnificat, Evening Prayer II for the feast of the Epiphany, Christian Prayer: The Liturgy of the Hours, Daughters of St. Paul, 1976)
The season of Christmas / Epiphany is great time for Births, Baptisms and Weddings!
[P.S., for extra credit: As a meme, hipsters don't understand "epiphany" any more than they do "irony".]

Become one every day
What Do I Want To Become - Every Day?
“It was in Antioch that the disciples were called Christians for the first time” (Act. 11, 26) ...
To be a Christian means to go up to the mountain to which Christ leads us. To enter into the temple of the living God that is formed in us and in our midst by the Holy Spirit. To be Christian means to continue to become Christian, learning from Christ the ways of the Lord so as to be able "to walk in his paths" (cf. Is. 2, 3). To be a Christian means to become one every day, ascending spiritually towards Christ and following him. In fact, as we recall, when Christ first called those who were to become his disciples, he said to them: "Follow me".
I can still hear these words the way Pope John Paul II pronounced them, in his steady and careful way.
The quote is from the address he gave at the Mass at Candlestick Park, San Francisco, September 18, 1987.
This dialectic of being and becoming is central to every aspect of our identity. For example, a license and a ceremony can turn a single man into a husband (in a way), but being a husband requires taking up the task of becoming a husband every day. A biological juxtaposition can turn a childless man into a father (in a way), but to really be a father in a meaningful way, the man must enter into the character of fatherhood, walk the walk of fatherhood, and be a father by becoming a father every day.
Aristotle uses the term "actualization". Potentially being can turn into actually being. How? By doing the impossible: by actually being what you are not. The example I remember is playing a musical instrument. Say someone doesn't know how to play the piano. (Well, how could he play the piano? He doesn't know how!) In order to learn he must practice, which involves -- actually playing the piano. If to play and to not-play were somehow radically exclusive, all learning would be impossible. In the real world, however, people do learn to play the piano. They practice, and little by little they play more and better. Actualization.

Okay! Everybody back on your heads!
Bleeping computers.
Bleeping automobiles.
They give you fits. And the older and more sophisticated the inhabitants of Casa Crowndot become, the more computers and automobiles we have. Which can be a good thing. But not when they break.
I just don't seem to have as much enthusiasm for this car stuff as I did when I was 16. Or as much enthusiasm for the computer stuff as I did in, say, 1984 ("But! Guys! Computers!!!1!").
Which is prelude to an excuse for not tacking new notes to the ethertubes for a while. Well, first things first, which this is not.
