Dragonfly weathervane

Dragonfly weathervane concept design

This is an untested design, so adjustments and alterations may be required. It is a basic design that could be altered so that a propeller could be added if you wanted to turn it into a whirligig. The pivot pin has been mounted as far forward as possible so that the dragonfly is always flying into the wind. It may be necessary to move the pivot pin slightly back for added strength depending on average wind speeds. Here in Nevada wind speeds can gust upwards of 60 miles an hour or more and may require that the wings be mounted more flat or even a downward slant to prevent dragonfly from being blown off the pivot post.
Although this design is presented for entertainment purposes it could quite easily be used as a pattern to create the actual weathervane.
