    Kelvin Balls -named after William Thomson, later Lord Kelvin. When not making navigation safe, he gave us the absolute temperature scale named after him; the first and second laws of thermodynamics; developed the first devices capable of accurately measuring electrical forces; who helped perfect the Transatlantic telegraph cable; and invented 'the siphon recorder', the ancestor of the inkjet printer.

    Thank you for the memories. As I listened to your explanation, my late maternal grandfather's voice was echoing in my head as I remember him explaining his craft to me. He was a Professor who taught Navigation, marine focused Wireless Communications, and Naval History. He was also one of the best Compass Adjusters on the West Coast.
    He died of cancer in 1993. His name was Robert E. Larson.
    I was just a baby when I first met the sea
    Twas my father, grandfather, the Skipper, and me.
    The salty sea splashed me, I started to cry.
    Grandfather smiled, then laughed and asked why
    "That means the sea likes you; she gave you a kiss.
    So blow a kiss back and say 'Thanks' for the mist."
    Now, all these years later, on the South Salish Sea,
    With memories of father, grandfather, and me,
    I stand on the deck of the Samish ferry
    Getting salty sea kisses from my Lady, the sea.

    Great explanation of “Swinging the Compass”. The same kinds of problems occur on airplanes as well. We have to record the errors that remain on a small card that is kept with the compass for our Cessna 172. We also want to take into consideration that vertical component that will cause a compass card to dip as one gets closer to one of the poles. The dipping of the card can actually cause the compass card to get stuck and not spin toward its new reading in some cases.

    That was absolutely fascinating- a far more complicated set-up than I had previously thought. I've searched my now-fading memory, but I do not remember magnetic compasses on any of the ships upon which I sailed, although I have seen these binnacles elsewhere. I remember the gyrocompasses. Iron ore from Canada was a frequent cargo, so I imagine that prior compensation for that would be very difficult for magnetic compasses.

    I've calibrated an aircraft compass. Similar principal but a radically different looking device. (There's also a lot less iron in an airplane, not as much less as you might think, but certainly a lot less than a ship. The radios cause more interference in an airplane :p )

      What part of a plane is made of iron ?
      Also a typical cargo or passenger plane is at least 100 times lighter than a cargo ship

      @@YounesLayachi the base structure is usually steel, or a steel aloy (which has iron in it.). The skin is aluminum and some of the frame can be, but a lot of the structure is steel. Titanium is sometimes used but that metal is very expensive so, the entire plane can't be made of titanium unless you have infinite money.

      Mostly between 1850's and 1880's i.e. in the first 30-50 years after iron ships became the dominant form. Some stuff was known earlier, and I imagine the precision of the adjustment increased steadily over the following 150 years, like most machines.

    I was briefly a suspect during my Day Skipper practical when the electronic compass on the yacht went wrong - the skipper knew I'd bought a large stainless steel cooking pot in the previous port. Thankfully, he soon ascertained that my purchase wasn't at fault, and to this day - over 20 years later - the pot still serves me well for a monthly batch of stew 🙂
