Flying Solo

Way back in the dark ages when I was single and in college, I seriously contemplated spending the time and money required to get my private pilots’ license.  I even went so far as to get a few hours behind the controls of a Cessna 182.  It was enough to convince me I would love it and that I couldn’t afford to maintain it as a hobby if I was ever going to have a family.   I gave up my quest before my first “solo” flight.  I was disappointed, but accepted my fate with magnanimity; knowing that my first solo take-off and landing would have been a huge blast.

I had a similar experience a few years earlier without leaving the ground.  I have always loved being in control of anything with a motor and wheels, so it was a huge thrill the day I finally completed all the requirements to drive a car without direct supervision.  Driving solo was a huge landmark I had sought after since I first realized I could reach the gas-pedal and see over the dash at the same time.

Based on these two experiences, it might be reasonable to extrapolate that doing things “solo” is the logical end-state of development.  As we learn and grow here in this short life, we should strive to get better at them until we are capable of doing it on our own.  This however is a tremendous fallacy.

Consider the pilot scenario above.  It’s true that as you progress in development, you get to a point where you are capable of handling a well-behaved aircraft on your own, but that is far from the pinnacle.  Consider the cockpit of commercial flights.  As a general rule, these flights are made up of a flight crew with both a pilot and co-pilot.  While part of the motivation for this is redundancy in case one of the crew becomes incapacitated, the real reason is the capacity for load-sharing.  During the more critical portions of flight such as final approach and landing while on instruments, the pilot can become quite busy flying the airplane.  In addition to actually flying the plane, radio communications pick up during this phase of flight and include changing radio frequencies several times, not to mention additional activities and preparations.  By working as a team, the pilot and co-pilot are able to level out the load, sharing the tasks and cross-checking each other to ensure things are done correctly and efficiently.

In the case of a car, it didn’t take long for driving by myself to lose it’s appeal.  The radio and the open road (or congested street more often than not) was a poor substitute for having friends, then girlfriends, and eventually my own family with me in the car.  Focus shifted from driving as an end in itself to a means to get somewhere to do something.  In general, going somewhere is either a non-fun requirements-based thing or I’m taking someone with me.   Driving solo isn’t all it used to be cracked up to be.

So, why on earth am I talking about flying or driving solo…  I can’t remember how many people I’ve run into who’s pinnacle was being independent and on their own.  Friends and co-workers have  indefinitely postponed marriage and/or family because they don’t want to be “tied down.”  I’ve known far too many who left marriages and children in an attempt to seek “fulfillment”  free from the “restrictions” of family.  This universally saddens me when I encounter it.

When I was much younger, I made a high priority of moving out on my own and tackling life alone.  At first it was great being free to do as I chose, responsible to nobody but myself.  However, as I gained experience with the “single life,” I quickly realized how much of a load of crap I’d been sold.  As I gained more and more experience with it, I got more disillusioned, and eventually moved back in with my parents where I had a support structure compatible with my values.

Over the years, I’ve had the opportunity to re-evaluate this concept as I’ve been compelled to fly solo in life for periods when I’ve been called away from home for work or other reasons, and it’s given me opportunity to reflect on the situation.  I can’t for the life of me understand why anyone would intentionally choose to be alone.  On my own, I’m solely responsible for taking care of ALL the necessities ranging from cooking to shopping to laundry to completing my normal work.  That, on it’s own, isn’t too bad.  However, I find it’s the intangibles that make the most difference.

I’ve had the opportunity to explore  a wide variety of museums, cities, parks, and other attractions around the world during down-time on business travel.  In the best cases, I’ve had traveling partners who shared the experience.  However, those relationships are transitory, professional, or casual, and the richness that would result from sharing experiences with my family just isn’t there.  While I enjoyed visiting the Hyde Park in London, I experienced it on my own, and don’t have common experiences to re-live with someone who cares.

The more time I’m compelled to spend on my own, the more I appreciate the miracle that is family.  Learning to solo an airplane is just the beginning of a much longer process of becoming a fully qualified pilot.  Learning to trust and work as a team enables a much more diverse and interesting range of possibilities.  My family is my team.  They help me do more and be better than I could ever be on my own.

Burden

The truth will set you free they say,
Give you strength and show the way.
Help you stand when threats come strong,
Make clear the route to carry on.

Sometimes it's true that truth is kind,
Healing hands and heart and mind.
But all too oft it carries weight,
Truths that grind, and crush, and grate.

A knowledge of a harsher sort,
Breaks through to light, a sharp retort.
The darkened hearts that plot and plan,
To hurt, oppress, and exploit man.

Patterns followed o'er again,
Truth and right now labeled sin.
Done before, the outcome's clear,
But boldly on, the crash comes near.

On every side distinctive signs, 
describe the flaxen cords that bind.
Yet no one stirs to shake them off,
Some warn, entreat, but yet they scoff.

To see the truth through sophistry,
An ancient path of catastrophe,
Makes knowledge a burden heavy and grave,
No freedom here... I am truth's slave.

Company Man

While much of the poetry that I write is deeply personal, this one stems from an experience I had helping a friend and colleague through the collapse and beginnings of reconstructing his marriage.

Twenty years he towed the line,
In the lead or just behind,
Purpose bent to meet his task,
Ever solid, firm, steadfast.

Many nights would find him still,
At his work for hours 'till,
Exhaustion bid him pause a while,
Then homeward trudge without a smile.

Daybreak bids him e'er again,
Drawn as moth to candle's flame,
Weary eyes in a care-worn face,
Search for meaning in this place.

He comfort seeks in a future distant,
When the work will all be done,
Yet each day the tasks insistent,
Bid him stay 'till time is gone.

While in his poor neglected home,
His life's companion sits alone,
Grieving over memories dear,
Of promised changes ever near.

All alone in thought and deed,
Her guard let down, she feels a need,
Then knocking at her lonely door,
Ancient friends entice her more.

Hardening with cold neglect,
Losing e'en her self respect,
She wanders off the beaten path,
a one-way road - no turning back.

One halt step to test the road,
And swiftly others more profound,
'Till shucking off her heavy load,
Faith shatters on unholy ground.

Youth now entangled by the fray,
Their children know not how to pray,
Or whom to ask for lighter loads,
Ne'er taught to seek in His abodes.

The promise made of finer things,
A house of playing cards now seems,
They never wanted more than time,
To share their thoughts and speak their mind.

They see the strain in mothers face,
Her tender heart with ice replaced,
Withdrawn and secret, pained and sore,
She loves their father now no more.

Pulled and yanked at every joint,
they wish for what will never be,
Voices shout and fingers point,
A shattered future now they see.

In days gone by 'midst hope and joy,
He'd scheme for idler times employ,
Speak of happy things he'd do,
When the work was truly through.

Yet every time he'd start anew,
Some labor kind, or service do,
In habits set, he quick returned,
To toil in his profession learned.

Seeking joy where never found,
Dashing hopes on stony ground,
Accolades and praise received,
Clearly had him then deceived.

Now too late begins to dawn,
Through misty eyes and broken heart,
How changes made so early on,
Can stop the pain before its start.

Monumental

Large even from an airplane window seen, 
sixty miles away.
Built to send people where nobody's been,
the vacuum of space. 

Buses could park on the stripes of the flag,
if it laid down.
A symbol of pride, a nation's great brag,
look what we did.

Here they built monsters of metal and flame,
they tore at the air.
Hyperbole claimed we would conquer and tame,
the vastness of space.

Pushing man and machine to limits then past,
They risked all to explore.
Lionized pilots who flew fearless and fast,
some died on the way.

The men are gone - the structure stands still,
shelved to history.
A monument to engineering, cunning and will,
empty and mute.

Will I ever learn?

A few months ago a friend was having car trouble.  She was broken down on the side of the road, and her husband was at work in town and couldn’t get there to rescue her any time soon.  She called Liz who went to pick her up.  That’s where I got involved.

Her husband is mechanically inclined and experienced with minor repairs and routine maintenance, but he hasn’t done a lot of troubleshooting of major failures.  He had spent two days doing what he could, trying to figure out what was wrong and get their car back on the road.  In the mean time, she was borrowing our car when we weren’t using it to run to her late-night shift.   In an effort to help them, I offered to go take a look.

Based on the description I got of the way the car was acting when it quit, it sounded bad.    It sounded like a major over-heat.  When I got there, it was obvious there were serious problems…  Just the sound of the engine cranking made it clear there wasn’t much compression.  A quick compression check confirmed that in dramatic fashion.   We were looking at a blown head at least, maybe worse.

A sane person at this point might call a tow-truck, a mechanic, or junkyard and car dealership, but I guess I’m not all that sane.  “Sure,” I say, “we can tear down the top-end, look at the head and cylinder walls, and decide from there how bad it is.”  We towed it to my house and spent several hours stripping the head off of the block, cursing the engineers who designed it every few seconds as we struggled to fit tools and sausage fingers into spaces too small for children’s hands.   At the end of our hard work, it was clear the head was significantly warped, which would account for the crummy compression and fit with the diagnosis of a substantial overheat.  The cylinder walls looked clean, so we took the bet the block was OK and sent the head off to the machine shop.

Along the way, I missed some things that should have tipped me off to what was in store…  When we drained the oil, it looked like no oil I’d ever seen.  It was milk-chocolate brown and smelled funny.    Then, when the machinist went to work on the head, it was so warped that they had to heat it up, press it flat, let it anneal, then machine it.  That was something completely new to me.  Then, the service manual was wrong on several points, and the overall accessibility and serviceability of the car made even simple things incredibly difficult.  The oil and warped head should have clued me in to the fact that the motor got hotter than any I’d worked on before, and the rest should have convinced me that I ought to stop there.  I didn’t.

We got the rebuilt head back and installed it after a few runs to the dealer to get a specialized timing tool, bolts that had sheared off, and random other things I didn’t have in my kit.  After much pain and many skinned knuckles we excitedly turned over the engine.  Such disappointment…  It started, but wouldn’t run without feathering the throttle, and it had no power.  There were no engine trouble codes in the computer, but something was wrong.  In desperation we returned to the compression check (after several hours of head-scratching, troubleshooting, and just plain being stumped).  All four cylinders were about 60% of the rated compression.  While the cylinder walls looked fine, the rings were blown, and the bearings were probably not much better.

$700 in, and it was for nothing.  Now we had to take the block out and get it rebuilt as well.  The first call to the machine shop  stopped that idea in it’s tracks.  They wanted as much as a completely rebuilt long-block just to rebuild the lower-half.   The only logical solution at this point was to order a re-manufactured crate motor and flush the $700, busted knuckles, and hours of work we had already put in.

That was three months ago.  The owners were tapped out with the work we had already done, and Banny (my friend and the car’s owner) decided he had to take a second job and save for a while before they could seriously entertain the possibility.  In the interim, they acquired a cheap junker so they wouldn’t have to keep borrowing cars to get to and from work (30 miles away in the city). That turned out to be one of the smartest moves possible in this sad situation.

They dutifully worked and saved while their car collected dust in my garage.  Last week (two days before Christmas) the new motor arrived.  Thinking it would make a nice, if slightly late, Christmas present to have their car back, we spent that afternoon and a few hours on Christmas eve pulling the old motor. Things went as I SHOULD have expected… as opposed to how I THOUGHT they would.

We decided to pull the whole engine/trans-axle  assembly as one unit based on advice harvested from on-line forums.   That meant disconnecting the axles from the transmission.  No problem.  I’ve pulled several trannies, re-built many CV-joints, and have always been able to get the axle halves out of the steering knuckle (usually the hardest part for me) by hook or crook.   It didn’t matter what we tried, we couldn’t get them to separate from the hub.  Heat, wheel puller w/ high-torque impact driver, vibration, shock, sledge hammer, combinations of the above, you name it… we tried it.  I’ve NEVER had an axle that was so hard to remove.  In the end we opted to dismantle the entire front-end suspension and never did succeed in doing it the “right” way.  Ugly,  but it worked.

After getting the axles free and disconnecting everything, we hooked up the hoist and pulled the mounts.  I didn’t expect major problems.  I expected to simply crank the assembly up and out.  But then again, I hadn’t expected much of what we had encountered.  We had to remove lots of stuff while the motor was hanging by a chain supported by only a hydraulic ram (not a comfortable position for me).   Even then, we were barely able to get it out by radically tipping, rotating, nudging, shoving, prying, and coaxing it out.  At that point, it was time to clean up for the Christmas eve party with extended family, so we lowered the motor onto a pallet and called it a night, happy that we had gotten that far and confident that one more day would see the car pulling out of the garage under it’s own power.

Plans to use Christmas day to  finish the job were kiboshed by Liz as being too Grinchy…  She’s right, but I would have done it had she not told me no.   The next few days were taken up by work for both myself and Banny, so we didn’t get back to it until Tuesday when we mated the engine and transmission, and transfered parts from the old motor to the new one.  The real fun started yesterday (New Year’s Eve).  Beginning at about 2:00 in the afternoon, we worked until 2:00 in the morning, ringing in the new year with an engine mounted to the transmission and installed in the car. There was still some work to do, but we expected a few hours of connecting wires and hoses, timing the motor, and other minor work would have us on the road again.  The last thing we decided to do before we called it a night was to check the cam-shaft timing.

We pulled out the trusty specialized tool, and went to rotate the motor to the right position (Top-Dead-Center on cylinder 1).  The crank was frozen solid.  Something was bound up HARD.  I knew it wasn’t the motor because we had rotated the crank several times in the process of marrying it up with the transmission.  My heart sank.  It looked like the transmission was the culprit.  Did we really just spend a cumulative $2900 on an engine and a now worthless head rebuild only to have to replace the transmission?  It was time to call it a night. I went to bed angry and frustrated.

A few hours sleep later, and we decided to pull the transmission to get a better idea about how bad it was and to make sure it wasn’t the new motor that had seized.  If you’re keeping track, this would make THREE major removals back-to-back.  Getting up the energy to tackle one of them when you’re a shade-tree mechanic like myself is hard enough.  Doing it over and over again on a car that seems to always have one more trick up it’s sleeves is really hard.

After dropping the transmission out the bottom, both it and the motor turned freely.  We pulled the pan to look for chunks of metal that would indicate a major failure and explain the absolute unwillingness to budge, nothing but the normal fine metal filings on the pan magnet you would expect to see in a transmission with 100K+ miles on it.  We decided to take a leap of faith, hope the bind had been caused by a misalignment, replaced the transmission filter, axle seals, and pan gasket, and put the transmission back in place.

Once again, we figured we were on the home-stretch.  All we needed to do was bolt up the transmission, hook everything back up, fill up the fluids, time the engine, and we’d be done.  The crank and camshafts were factory timed (and verified by us), so all we had to do was time the crank position sensor.    The belt pulley on the front of the motor has a set of “teeth” on it that encode the crank position for the computer to use for setting timing and other purposes.  The pulley isn’t keyed, so it has to be installed with specialized tools to make sure it lines up properly with the sensor.  The factory had supposedly already done that, but when we went to align the sensor, things didn’t match up.  The pulley was off by a few degrees, enough to prevent the encoder tooth from aligning properly with the sensor. To complicate matters, the shop manual was completely and undeniably wrong, so we had to rely on a combination of internet research (a process that devoured several needed hours) and intuition.

The right way to fix the situation would be to remove the bolt that holds the pulley on the crankshaft, re-position the pulley, and tighten it down.  However, as with the axle-halves, there was no budging this bolt.  The shop manual calls for a specialized too that looks like a bent pickle-fork that holds the pulley in place while you unscrew the bolt.  We didn’t have the time or money to go back to the dealer and get a tool that we would only use once, so I went to the scrap pile and cut, welded, and blacksmithed my own version.  Too bad it didn’t work.  Even with extra bracing and reinforcement,  we couldn’t get enough leverage on the bolt to break it free.  You know it’s tight when two full-grown men can’t break it free by putting their full weight on breaker-bars that are over two-feet long.

I decided to try a backup approach I’d used before on a few other cars, and even on the other motor we had just pulled.  I hung a breaker bar on the bolt we needed to remove, jammed it against a part of the frame, and bumped the starter.  It’s ghetto, and kinda risky because the breaker bar can pop loose, strip the bolt, fly off, or hit other important things like break lines.  I’ve NEVER had this fail to break loose a tight crank bolt until now.  We gave up trying to adjust the pulley.  I’ll never understand why they couldn’t key the pulley like every other engine I’ve ever worked on.

The solution ended up being to modify the position sensor by reaming out the already oblong mounting holes to allow for a broader range of adjustment.  Too bad we didn’t do that sooner.  It would have saved me a few hours, lots of frustration, and some scrap metal for other projects.  That hurdle overcome, we assembled and connected everything else.  After a short break to let the gremlins out, we turned the key.

It started, but ran worse than the blown motor did after we finished the top-end rebuild.  Desperation and frustration were angrily knocking at the door.  However, unlike the first attempt after the re-built head, there were engine codes.  A quick trip to the local parts store to rent a code reader, and we were on the hunt.  After another few hours with a volt-ohm-meter and the wiring diagram (which was only mostly correct) and we found a broken wire hidden inside factory shrink-tubing connecting the coolant temperature sensor to the engine control module.  Turns out that if you feed a motor fuel at 60 degrees F they way it would at -40, it doesn’t run well.  Snip-snip, crimp-crimp, and FINALLY, it started and ran smooth.    It drove home early this evening.

I can almost hear the heavenly hosts breaking out into Handel’s Messiah, which would have been more appropriate had we finished on Christmas day like I wanted to…

Too bad my truck needed work.  Even after all that unexpected time bent over the hood of a car or crawling underneath it, I still had to spend several hours in the garage taking care of overdue maintenance on my own vehicle and cleaning up the mess we made over the last several months.  I’m sore in places I don’t remember using, and my skin is raw from abrasions; bruises; harsh automotive solvents, fuels, grease, and road grime; and the constant scrubbing and washing required to deal with the former.

When will I ever learn…  I should have walked away from this one from the start.  However, I never will.  I enjoy helping people too much.  As much as it can be frustrating, expensive, time consuming and painful, I like fixing cars for other people when they need the help.  Along the way, I got lots of time with a friend in the garage doing “man stuff” as Liz calls it, taught him a few things and tricks I’ve had to learn along the way, and helped put someone back on the road for less than it would have cost to pay someone else to do it (even with the sunk costs put into the original head rebuild).

 

Warnings

We must be warned that coffee's hot,
that smoking hurts the lung.
Knives are sharp and spoons are not,
and sunscreen blocks the sun.

We must not eat the non-food pack,
that freshens packaged foods.
Know calories might make us fat,
and sleep might make us drool.

Labels warn that water's wet,
and bullets might go bang.
Signs to warn of dangers met,
adorn each mundane thing.

We used to use our eyes and think,
to see, assess, then act.
Replaced with warnings bold in ink, 
a talisman of words and fact.

Speculation

If only people understood how un-cool secret stuff really is… Scott Adams came close in this strip:
Dilbert.com

The super secret squirrels convened
Their meeting in the vault
Each day at noon they gathered there
Discussing who knows what

The watchers all looked in from out
As blind and dumb and deaf
As though they had no mouth or ears
To use for baited breath

Whispers swirled from left to right
Then back around again
Tales of conquests in the works
Cabals of greed and sin

Murmurings of secret tech
Sensors, planes, and tools
Laser guns and mind control
Oh man... it sounded cool

While all along the secret squirrels
Sat bored and languid then
And hour by hour discussed at length
The font for slide one-ten

The Parrot

Almost endless years of school
Countless hours of study
Promotions moving ever up
An awful sense of duty

To be the expert and make change
A constant goal since youth
Use of hands and head at once
Connecting truth with truth

Explore and build to meet demand
Reflect on what's been made
More to know you've done it right
Than strictly to get paid

A phantom of some lingering dream
Haunting daily chores
Wants unmet in truthful life
Like salt in open sores

No new ideas are his today
Great works he builds no more
He simply gathers and compiles
Then brings it to the fore

With words they laud and stroke him
Encourage, praise and bless
But in his mind he is a fraud
A parrot or even less
