Made these drawing over lunch. Obviously I’m not much of an artist (at least not in 2 dimensions). They are the wind vane on top and the anemometer on the bottom. They are to be mounted one on top of the other on an aluminum rod with the wires running through the rod. The rod will be mounted on the top of the mast.
Most of the parts will be plastic. I’ll make wooden cones and cylinders and use a suck down (vacuum forming) machine to make all the plastic parts. The vacuum forming machine is a dental lab machine used to make night guards and bleaching trays. The arms will be carbon fiber rod.
