How to make a weather vane with a propeller

Weathervane with a propeller is the most reliable indicator of direction and the presence of wind. That is why so far he remains a fixture in any weather station.

However, it may be not only the measuring instrument, but also the decoration of your house roof.

You will need

  • - fanera-
  • - Glue EDP-
  • - kraska-
  • - Small Bearings-
  • - Propeller.



Before you build a weather vane, develop a simpledrawing. Decide on the size of the device, in the development of mobile connections refer to the size of the bearing. Observe the maximum possible wind speed at which the wind vane will work, and lays the details of appropriate thickness.


Cut out all the necessary details of thin plywood. From thick steel studs make a pivot. It will be subjected to strong loads from the wind, so be strong. The diameter of the stud should be not less than 6 mm. Part of the axis on which the body will be worn bearings, winding the thread is not necessary, the main thing - to have enough length of the protruding portion to fix the weather vane on the leg by a nut. Similarly, do the axis of the propeller.


Assemble the body, Glue for wooden bossbearings and propeller axes as well as the keel. It is best to glue adhesive using EAF. Secure the glued parts with clamps or strong wooden pegs. Be sure to insulate the pegs on the adhesive using scraps plastic bag, or pegs are glued firmly to the body of the wind vane. When the glue dries, using a drill, drill a hole in a wooden boss under the pivot bearings and then make a hole for the propeller axis. Glue the propeller axis, and then dilute with a little solvent ink and paint the whole body of a weather vane. The paint protects the wood from moisture and dissolve it should be for deeper absorption in the tree. For best results, paint the body in several layers with intermediate drying.


Make the propeller. Number of blades affect the appearance and complexity of manufacture. In the simplest case, you can use a propeller of the appropriate size of the model aircraft. Drill the center hole of the propeller under the existing bearings and, if necessary, shorten the blades, as well as insert bearings in the propeller. After that, if possible, balance it. To do so, the propeller vane on, secure it with a nut and screw position horizontally. If it is rotated, you can use sandpaper grind off a little with the material of the blade, which tends to leave down.


Assemble the stand weathervanes. Take the appropriate handle of a shovel and drill in one of its ends a deep hole. Glue pivot shaft therein. When the glue dries, paint the rack and push it ready weathervane. Secure it with a nut.


Balance the weathervane. To do this, using lead weights until you get to the front or tail parts are not outweighed and body in a state of equilibrium is horizontal. This ensures that the vane will always show the correct direction of the wind.
