I want to make a life-sized model of Sputnik. Answered
The original Sputnik looked really slick and threatening! I want one! Unfortunately, the original is unavailable, so I'll have to settle for something more modest.
The original Sputnik looked like the one in the picture. My goal is to make a model that is life-sized and pretty good looking. Coolness is paramount; precision and accuracy are not.
Does anyone have ideas about how to make the sphere part easily?
The criteria for my model sphere is that it needs to be:
Roughly 60cm in diameter (I believe the original was ~58cm)
Strong and rigid enough that I can attach the four antennas
Light enough that I can hang it from my ceiling
It is okay to be a little rough (i.e. it doesn't need to be polished steel or whatever)
Right now I'm thinking I should get a bunch of pieces of hard-cell foam, stack and glue them, and carve a sphere. Then I'll sand it smooth and spray paint it silver. Is this a good approach?
Any other ideas for the project?
