3D spherical Earth with epoxy oceans carved with 4-sided rotary CNC

This video shows the process of 4-sided CNC routing a spherical 3D Earth with a diameter of 200 mm (8 inch), using my manual rotary setup for the Shapeoko XXL. The Earth was carved from a solid piece of tree trunk with a diameter of 250 to 300 mm (10 to 12 inch), and the oceans were filled with a layer of 5 mm (1/5 inch) epoxy resin.

Software used:
– Meshmixer to create the 3D Earth STL files
– Vectric VCarve to generate the tool paths
– UGS Platform to send the Gcode to the CNC

Materials used:
– Tree trunk of 250-300 mm (10-12 inch) in diameter and 375 mm (15 inch) in length
– 1/4″ steel octagonal rotary plates
– Epoxy resin and different blue dyes from the Epoxy Resin Store
– 3 inch roughing bit: Amana Tool end mill #45210-3
– 3 inch finishing bit: Amana Tool ball nose #46286
