HOW IS MY EDITING?


This is what happens when I can’t sleep. How am I doing as a photo editor?

 

THE SEARCH IS ON! WELL, DAVID IS LOOKING FOR THEM OUT IN THE GARAGE.


Hank and I did some thing which, for us, was completely foreign to our lower middle-class lifestyle. We had been friends for a while as we had shared many experiences in mountain climbing, teaching mountaineering to beginners, and generally enjoying life in the High Sierra backcountry. One day, Hank asked me if I would join him on a kayak trip to explore Glacier Bay. After I got over my surprise at the request and after his explaining that the Glacier Bay that he was referring to was in Alaska and the the fact that I had never been in a kayak was no reason to say no and that we had survived mountaineering school on Mount Rainier without mishap, I said yes. But, I first had to ask my wife Patty if she was OK with the idea. She finally gave me her blessing after I assured her I would learn how to paddle a kayak before I went. She seemed to think this was important. Well, to make a long story short, Hank and I went to Alaska and spent almost two weeks exploring Glacier Bay. I intend to relate that experience but not in this Posting. Later, I will, after I find the photographs and negatives. I took several hundred color photographs, had the film developed and printed, showed them to a few persons, and then put them away in the garage. Other than telling a few stories to Patty, I have never told anyone of our Glacier Bay adventures. We should be dead, but, we survived in spite of our nautical naivete. I normally used slide film and and had slides to show as I related my stories. For reasons long lost to my memory, I used color film on the Glacier Bay trip. It is simple, no slides, no stories! I ran across the storage box with the photographs during rare garage cleaning episodes so I know they are in the garage. I have been thinking of scanning the negatives and writing about our trip and showing my scanned images. I believe it would make an interesting story, but we (David and I) have not been able to find the negatives or the prints. He, David, is looking in every box and this takes time as I have much “stuff” stored in the garage.

I think I need to explain to the less old of my readers that these events took place long before computers and scanners were commonplace and I had no choice but to wait these many years.

In the interest of transparency for my true reason for my writing this Posting, I must tell you I could not sleep tonight and I got out of bed to write something and this is the best that I could come up with. But, I am still not sleepy! I think I will stop writing and go turn on the TV and catch up on the late news. That should do the trick!

A WELL SPENT SUNDAY AFTERNOON AT REDONDO JUNCTION – 1968


This is why I spent a few Sunday afternoons at Redondo Junction near downtown Los Angeles. The year was 1968. It has changed a little, but its still there – sorta.

THIS IS A TEST


I present this image as a test of your modeling sensibilities. I assert that you lack the ‘right stuff’ to become a true modeler of railroad rolling stock if you heart does not  skip a beat when you see this image. It has it all! The flatcars can be easily modelled from readily available cars and the ‘big watchmacallit’ on the cars is simple to model. Have fun! 

MY MOTHER AND HER DAD


MY MOTHER AND HER DAD

I believe this photograph was made when my mother was three years old. I further believe  it was taken on the occasion of her adoption by the Powell family. Her mother had died and her father could not care for her. I do not believe she ever saw him again. He died the year I was born, in 1932. My mother was born in the town of Olds. This town is located in Alberta Province, Canada. I consider myself as half Canadian and half US citizen. I think I can see something of my brother Don in my grandfather’s visage. I can see my sisters in mom’s face. We have a large number of cousins we have never met who live in British Columbia, Canada.

WHY YOU NEVER HEARD OF THE AUTONETICS G22 GYRO


At one time in my career at Autonetics, I was assigned the task of designing, building, and testing a miniature version of the G6 gyro. I was tasked to design the gyro to include as many performance enhancing  features as I could find space for. The yet to be designed gyro was designated as the G22 gyro. It was a dream assignment for sure.

Over the years, I had developed an informal ‘list of improvements’ I would try to incorporate into any free rotor gyro design projects I was associated with. These ‘improvements’ were the result of my belief that our free rotor gyro designs should be based on the principles of simplicity, symmetry, smoothness,  purposeful cancellation, and balanced energy centers. Except for the mandate that the gyro was to be a small free rotor gyro with a spherical gas bearing, ie, a miniature G6 gyro, I had a clean sheet of mylar to lay my gyro design on. My dream assignment had a darker flip side but I did not pay much heed to the details of that part of the task as there was nothing I could do to mitigate these conditions. The  drawings would be made by my long time associate, Antonio ‘Tony’ Carrenza, and I would have access to experts with many years of experience in designing motors, torquers, electronics, gas bearings, test equipment, and tools. Tony and I literally started with a blank Mylar sheet. He laid out the gas bearing and we designed our little gyro around it using the principles listed above. I sometimes wonder what became of this drawing. 

It had been my experience that the machining tolerances of the component parts of our gyros were too restrictive and did not adequately take into account surface  finish. I also had questions about the statistical assumptions that were made as part of the tolerence setting process. I remember trying to set tolerances that were loose enough to not require otherwise unnecessary smooth surfaces and at the same time protected the interchangeability of mating parts. The contour of the interior and exterior surfaces were of concern as they were often the determining factor in the selection of the machining process. It was my goal to keep the machining of the gyro parts as simple as possible.

I remember spending a lot of design time on the motor and torquer interface of the gyro to maximize the symmetry between the motor and torquer halves. I believed that a successful design requires that symmetry with respect to the center of the gyro be maximized. I believed that deleterious effects often cancelled each other out and it was to facilitate this that symmetry across the center line of the gyro was sought.

The fill gas rotated at speeds in excess of 100 mph and the ‘smoothness’ of the interior space of the gyro presumably had a lot to do with the turbulence of the gas and the random drift of the gyro. The proximity of the interior surfaces to the rotor was balanced between closer for laminar gas flow and further away to minimize drag on the rotor. I remember consulting with our gas bearing expert on how much drag we would have for a given interior space configuration.

In keeping with my goal of symmetry across the gyro centerline, I had Tony design the motor and torquer halves to be as similar as possible. The most obvious difference between this and previous designs was the addition of a speed control pickoff to the torquer half. This was done to balance the spring rate effects of the case-to-rotor angle pickoff in the motor half of the gyro. The G6 gyro had a low spring rate due to to fortuitous  spring rate cancellation effects and it was planned the G22 would benefit from this as well. 

After six months of work, the technicians in the cleanroom were close to final assembly of the first gyro when I had a visitor. He held the title of Chief Scientist and a Phd. degree. I knew him as a fairmined person and I respected him. He was there to hear from me about the work we were doing in bring the design of the G22 to a successful conclusion. I told him the complete story of the work, warts and all. When I finished, he knew in detail what I knew. He then explained that he was reviewing all IR&D projects with the objective of eliminating those deemed not in line with current IR&D needs. My G22 project was on the block because the G22 was an ‘orphan’ gyro, ie, it did not have a designated system use at Autonetics. That was the dark side of the project that I referred to earlier. Shortly after, I was told that my task was ended and I was to stop all work except that necessary to bring about an orderly end to the project. Since the Government owned everything, everything pertaining to the G22 project was boxed up and shipped to ‘who knows where’.

That is why you never heard of the G22 gyro and why I will never know if we would have been successful in meeting our design goals. It is like an itch you cannot reach to scratch – frustrating! 

 

 

THE HOME FRONT IN 1943


Here is proof that Norwalk was ready for anything during WW II. We had just returned from a mission when this photograph was taken.
