Together with my friend Adriano we made a 3d turned puzzle. The pieces are made of 2ch high wall nut. Some have three layers of obnoxious shapes, making it mind boggling to assemble. But the turning was another challenge as the rotation of the lathe dismantled every thing.
The globe is about 14" in diameter.
Continents are painted with acrylic, the borders are designed with a kind of coloured glue that is sold in small tubes.
