Boat Steel – Day 6

2013-01-12 13.47.38

I’m not a metallurgical engineer by any stretch and I don’t have a clue about the steel that was and is used to build submarines other than the fact that I have a 2″ cube of HY80 submarine steel.  It weighs a heavy pound and the pressure hull – we called it the “people tank” – on our boats was made out of HY80.  It would creak creak creak each time we went deep and then when we would come back up for air.  From what smart people tell me but also from first hand experience, the HY80 was good stuff and it kept us safe all the time that we were submerged.

During a shipyard period, the shipyard workers had to cut a big hole in the back end of the boat so – they were nice guys – they cut out a bunch of 2″ cubes of HY80 for the boat’s crew members   I’ve had the square sitting out in the living room on a shelf for years.  I have always been careful, however, to not let someone – especially a little kid – grab it and then accidentally drop it on themselves.  It would definitely badly bruise or break a toe!

Since the Internets can tell you more than me about HY80, I copied a short article from here and reproduced it below:

HY80 steel and variants, a flexible steel alloy, has for decades been used on modern U.S. and Allied submarines. Its flexible properties are what makes it an asset – it contracts and expands as sea pressure increases/decreases with submerged operations. Internal submarine decks are not actually attached to the hull – they’re actually hanging from suspended cables [the decks on our boats sat on rollers that ran in tracks that were attached to the pressure hull] and the decks are several inches from the sides of the hull to allow for the contraction as the boat goes deep.

[Years] ago, there was a lot of controversy about the Russian ALFA class Fast-Attack and her known Titanium hull, able to reach depths near 3000′. 

Titanium is extremely strong, but it is not flexible – sure, the ALFA can dive deep, but each time it puts stress on the hull when it deep-dives it becomes more brittle over time. It’s like putting increased pressure on an eggshell – eventually it’ll crack. This doesn’t happen with HY80. It remains flexible over decades and hundreds of dives and surfaces.

So that is that.  Since the days of HY80, newer submarines are being built with HY100 and even HY130.  The difference between these steels is that the newer steels have a higher pressure rating.  Meaning – deeper dives!

World View

charlesSomething to Think About
Charles Jackson
Jan 24, 2013

“His disciples asked him what this parable meant. He said, ‘The knowledge of the secrets of the kingdom of God has been given to you, but to others I speak in parables, so that, —“‘though seeing, they may not see; though hearing, they may not understand.'” (Luke 8:9-10)

“World View” is a term that men have coined to convey an idea. What does it mean? It does not mean the way the world truly is. It does not mean the way the world should be seen. It does not mean the way most people see the world. It means the way you see the world. World view is something everyone has, and, no two are exactly alike. Why so? Because it’s a thing fabricated from all past experiences.

One’s world view should be ever changing. (If not, one is suffering from arrested development). Here’s an example: Mary and I were parents at a very early age. We practiced parenting much as our parents before us…it’s all we knew. I would do it differently today. I often apologize to our two sons for my mistakes as a father. My world view of parenting has evolved.

Likewise, and briefly stated, my world view of God and Bible content has evolved.

World view is cultural, geographic, ethnic, demographic, and etc. It’s also one of the greatest causes of division and conflict among people. We see things differently. What can we do about demanding everyone to see –and do everything just as I do?

Here’s the way out. “But the fruit of the Spirit is love, joy peace, patience, kindness, goodness, faithfulness, gentleness and self control…” (Galatians 5:22ff)

More Real Photo Proof – Day 7

2013-01-12 22.01.02

Here are a few more photos from a different era.  These came from the months that we lived and worked in Salt Lake City prior to and during the Salt Lake 2002 Olympics -we worked in Salt Lake City for probably a year and literally lived there for about three months from Jan – Mar 2002.

Truly, we look much meaner in this picture than we really were.  These were some demented and crazy people.  If we had not been able to laugh and play tricks and put up with some outrageous antics, we would not have survived together.  The goofy guy in the skin hat was my live-in roommate though we rarely saw each other because he was night shift and I was day shift.  (He kept the hat tied up and fed outside when he was at our apartment.)  Long hours and hard work but a very interesting and very satisfying experience.


We had a location near Ogden where we spent hours and hours testing and preparing all kinds of equipment and methods.  And the place didn’t have any heat!  So, we had to procure space heaters to keep warm.  But even then, it was cold inside.  I’m not sure but I think each one of us got sick somewhere along the line simply from having to work inside of this cold and isolated facility.  But this is where a great deal of magic occurred – it was amazing.


Time for another contest.  If you know who this sports legend is – no, not me! – and can tell all of us his name and claim to Olympic fame here in the comment section then I again will present to you a $25 gift certificate.  (I know – I am a very generous person.)

In this photo, we are holding the Olympic torch that he carried a few weeks prior during his short torch run near Salt Lake City just prior to the opening of the Games.  Each of the torch runners were able to keep their torches – that must have been a lot of torches to be passing out by the lead torch vehicle all day and all night.  Anyway, one day this nice man came by our location and visited with all of us – a very nice and interesting and storied person.
