Above- 2 1/2 minute video showing how to carve an ice sphere
Below- Step by step instruction
For a large sphere freeze 2 pcs. together.
This cube is 15” x 15” x 15”
Starting with a perfect cube will allow you to make a nice sphere
(Example- 15 x .29=4.35”) Scribe lines
on all sides of the cube 4.35” from the edge
Use a Layout Jig to scribe the lines
(Hexagon from top view)Be careful not to cut inside the lines
Rotate the Ice & cut off 4 corners, using the lines as guides
Notice the foam under the carving? This protects your saw
Carve 3 hoops around ice
in a circular pattern
sand the whole surface
The above sphere took 45 minutes to make using these methods (including photography).
My system is a compilation of the following 3 techniques-
1. The Old Japanese “Carve 3 Hoops” technique.
2. The “Make an 18 sided shape” technique.
3. Junichi’s “Finish with the sphere scratchy board” technique.
