This 16mm reel from my collection is a work print and has no soundtrack, but the unedited rushes show many workstations and production steps in manufacturing hydraulic lines and fittings from raw stock in the 1950's. Filmed in gorgeous Kodachrome, many of the shots are not ideally focused and many are underexposed, but still an intriguing document to a largely bygone era of American manufacturing. As always this was transferred using my own Telecine. OH - and you get a little bonus at the end. What is it? Hell if I know! Enjoy!

    To this very day… Yup the lower paid assembly work is still dominated by women in many places. Inspection/metrology has the men. You can tell who the crappiest wage earners were in these old films simply by gender and race.

    1940s Kodachrome movie and slide film had an ASA (ISO) of 8 and 12. The early 1960s brought Kodachrome II which had an ASA of 25. Unlike the later released Ektachrome films, Kodachrome could in no way be push processed for an increased ISO speed the way the Ektachromes could. The two films and their chemical processing were vastly different. Kodachrome had more stable color dyes than the Ektachrome films too.

    Soul destroying shit is still a problem in 2022.

    So Fran. That piece of equipment you have as the thumbnail picture for this video. The thing that you mention reminded you of a projection screen in a Soyuz capsule. We still use to this day in manufacturing. The common term for it is a shadowgraph, but the technical term for it is an optical comparator. Although the newest models are digital not much has changed about them since the earlier part of the 20th century. In your video you can see the axial lines and the graduations around the circumference of the screen. Those knobs on the right are used to rotate the screen and the graduations are degrees. In it's most basic way that can be used to measure relative angles of a projected profile. The lens has certain magnifications so that you know how much the image is scaled from 0. So for example you would be looking at the profile at precise focus at 10 or 20x.
    Today's uses are many. For instance you could print out a profile from a cad system on mylar with a certain scale e.g. 10x with inside and outside tolerance profiles scaled accordingly, and place it on the screen. Then when you set your comparator at 10x and bring a complicated part profile into focus, you would know if the profile was within tolerance visually quite quickly and easily just by looking at where the objects profile lay relative to those tolerance bands. Rather than running a scanning CMM stylus around the part and then looking at arrays of numbers on a printout of those results. Which as you can imagine takes much much longer and can be difficult to interpret.

    No PPE on the factory work floor. These were tough people that got the work done. No lighting needed at the work stations! Lol 😂 😂 Women were there because men would go mad trying too do the hand eye coordination tasks. Many of the jobs that require hand eye, coordination, and sophisticated diagnostics women do much better. When the telephone company started to use operators that job had to be taken over by women because you weren't allowed to have a long conversation with the customer. The women operators were able to listen to the caller record the billing information and place the call for receiving party much quicker than the teenage boys they were first hiring.

    Fran, I'm assuming you're not married by the lack of a ring. How can someone so smart and pretty be still single? Must be by choice as it has been with me up until recently. Starting to rethink my decision though…

    You mention the dreariness of the workplace and mindnumbing boredom of the process worker . That just brought back all sorts of memories for me from my time as a teenager working on production lines . It is exactly how you imagined , so much so that my experience of it was enough to send me back to school to improve my situation . I was assembling electric motors on an assembly line and every day was like an eternity , by the end it was all I could do to purposely get fired so that I could get Govt. assistance to return to education . At least , I suppose , there was that silver lining .

    The Golden Hands of Kurigal has an entry on IMDB as an edited “movie” from a 1949 serial.

    keep the voice overs please
    thanks Fran

    The rough cuts of the film are great for keeping in those little human moments when the workers glance at the camera and give a wry smile or make a comment. Are you sure that's 1957? Like you said, the fashion is quite a few years earlier, especially the women's hair, which would be really unusual! Could it possibly be 1952? That 7 looks a bit dodgy to me.
    And the clip at the end, "Golden Hands of Kurigal" has some info on IMDB. It was a 1949 serial (Federal Agents vs Underworld, Inc) re-edited into a feature length TV movie. My opinion why they did it is because the main actor looks a lot like Robert Stack, who was starring in a movie with a not dissimilar premise at the time, "The Corrupt Ones".
    Edit :Federal Agents vs Underworld, Inc is on YouTube in colorized format!
    Another edit: The star of that movie was Kirk Alyn, the first live action Superman. Thought that was interesting. Sorry tend to waffle.
