Erratic wind vane
« on: April 30, 2012, 04:16:16 AM »
I have an AAG WS603 and the wind vane is very erratic.
Does anyone know how to design a wind vane to achieve the correct balance so it remains reasonably steady?

I have a wind vane that is very erratic. It is nothing to do with the vane, just the siting of it. Mine is affected by nearby obstructions such as chimneys and roofed. The vane is very erratic at low wind speeds and fine when winds are above a few miles per hour. My solution was to put the vane on as high a pole as possible. I then tapped a few washers to the weighted nose of the vane so that it needed slightly more wind to move it. This is not ideal but gets me much better results. Key is to get the right balance of additional weight. Too much and the vane won't move at all!
