9191 – Weather Vane | The Factory Shop

By: The Factory Shop  05-Apr-2012

Great for the top of house or barn, or shed. Points in the direction of the wind. High quality. Easy to assemble (as shown below).

Height 45cm

Assembly is relatively easy.  See the video above.  However, firstly open the box get the N-S and place it on top of the W-E.  Then the Rooster is paced on top of the “spindle” or “axle” on which it spins pointing into the wind.  There are a number of methods of attaching the weather vane to a house, fence etc.  The assembled weather vane can sit on the top of a dowel (like a broom handle), it will need to be screwed into position so that the whole weather vane doesn’t rotate, it must be fixed and only the Rooster should move.  There is a small indentation in the base which is where the screw needs to be placed – you may need to drill a hole out.

The broom handle (cut down to size) or dowel then can be fixed to the side of a house or fence.  Alternatively, a small block of wood could have a socket drilled out, using a “lock hole drilling attachment” to a drill.  The hole into which the dowel is placed should not go all the way through the wooden block as preferably two screws needs to come up from the bottom to hold the dowel in place, alternatively it could be glued into place with “no more nails”.  The block is then screwed to the top of the house or turret… MAKE SURE THAT THE “N” FOR NORTH IS ACTUALLY POINTING TO THE NORTH.

What is a Weather Vane and how does work?

A weather vane is an instrument for showing the direction of the wind. They are typically used as an architectural ornament to the highest point of a building.  Although partly functional, weather vanes are generally decorative, often featuring the traditional cockerel design with letters indicating the points of the compass. The word ‘vane’ comes from the Anglo-Saxon word ‘fane’ meaning ‘flag’.

The design of a wind vane is such that the weight is evenly distributed each side of the surface, but the surface area is unequally divided, so that the pointer can move freely on its axis. The side with the larger area is blown away from the wind direction. The pointer is therefore always on the smaller side (a north wind is one that blows from the north). Most wind vanes have directional markers beneath the arrow, aligned with the geographic directions. Wind vanes, especially those with fanciful shapes, do not always show the real direction of a very gentle wind. This is because the figures do not achieve the necessary design balance: an unequal surface area but balanced in weight. To obtain an accurate reading, the wind vane must be located well above the ground and away from buildings, trees, and other objects which interfere with the true wind direction. Changing wind direction can be meaningful when coordinated with other apparent sky conditions, enabling the user to make simple short range forecasts.
