Well, if you can't cut triangles, you probably won't be able to do this, either, but it's a good technique to contribute to the discussion.
In a nutshell, you would cut flat material to match the lines of longitude on a sphere/globe.
Then, you'd bend the resulting ()-shaped pieces into the radius of the sphere.
Then, weld them together.
Like the triangles, the smaller the pieces, the closer the approximation of a globe.
And, the number of pieces and the width of the pieces dictate the size of the globe - a 36" globe with 36 pieces 1" wide works. A 10" globe with 20 pieces would be .5" wide.
And, you'd know the length of the pieces because it's half of the circumference of the diameter of the globe.
