      No remote indicator or anything fancy, here's mine.

        Eddy curent brakes are used in Brille clocks to control pendulum swing and in Wixie angle gauges to damp the pendulum. They sound ideal for a wind vane. A friction damper would be prone to sticking just slightly off true position. If using 2 magnets just be sure that they are not in opposition

          So.i have made a small scale model of the proposed vane to test some theories. The bearing tube and thrust bearing work very well so that I have an output shaft I can use to drive the indicator.
          The actual pointer turns very smoothly but I didn’t balance it and I’m not sure how much of an impact that will have. It certainly turns into the wind due to the relative size difference of the arrow and tail pieces.
          I ordered a set of cardinal letters from e pay and will fit them when they arrive. Then I’ll post some images.
