Spacewalking astronaut and space capsule weathervane

Spacewalking astronaut and space capsule weathervane

   So the idea or concept was to create an astronaut walking in space. At first the design seemed to be simple, but as I researched it more I quickly realized that I could take the design to whatever level of detail that I wanted. For presentation purposes I have chosen a simpler design than what an actual astronaut and space capsule would look like. It may be possible to create lifelike replicas but as this project would be exposed to the elements I chose to keep it simple. This way if the weathervane should become damaged it would be easy to make repairs. 
    I chose a weathervane design to minimize moving parts but also decided to add what is referred to as a wobble effect. This is done by adding a part of the design to a spring, metal band, or spring wire. In this case I'm using spring steel wire as the astronauts tether. The bouncing around motion that the astronaut will give in the wind will add to the illusion of someone actually walking in space. 
    The space capsule is actually cut out of 1/2" wood stock and the lower flame is notched so as to fit over the side part of the pivot. The thicker Woodstock allows you to make a more secure attachment to the pivot and the overlapping flame at the bottom will give it a more three-dimensional appearance. It should also be noted that I have intentionally left off the country of origin insignia on the side of the space capsule. This is so that you can put your own insignia on the side of the space capsule such as an American flag or some other countries insignia. 
    The pivot itself is a basic design and you can refer to the pivot design at the bottom of the following post. windmillhorses-weathervane-whirligig
