Burningman 2007:
The Green Man
Skinning the Icosahedron
Now that I have an icosahedron, the tough part starts as I figure out how to cover the surface with wood while conforming to a spherical shape.

Setting up a sheet of plywood to be a measuring 'card' to determine where the surface of the sphere should be.

The semi-circular cut in the plywood is larger than the final ball. The paint brush bristles extend just to the future surface.

Not having enough brushes, I started attaching flexible straws to mark the surface.

After trying to use my external measuring card/straws, I decided that it was mostly unworkable-even if it does look good.

Instead, I found the center as near as I could and added a rigid stick to the center of the icosahedron with a string to measure out the 41" radius.

Here the first few struts are getting beefed up with some 2x4s to mark the surface of the sphere. Glue, and screw, glue and screw...

As much as possible, I want to use scrap wood, both because of the cost involved, and becaus it is more in keeping with this year's theme. It is gonna take somewhere between 1 and 2 thousand pounds of wood I estimate.

With the sides strengthened, its time to begin filling in the space between.

Using the string to 'aim' each board right at the center allows each board to be the same shape-an arc with a radius of 41".

Rough estimates say I'll need to cut 1500 to 2500 curved pieces like these.

Essentially, the entire surface of the sphere will be saw cut at some point, and most boards are also sanded before being added to the whole.

DONE! Now just 19 sides to go!

Ready to start on my other project-a glass logo of the Burning Man symbol for a good friend and great burner.
