 Square
up a block with a chainsaw
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 |

Multiply the width of the cube by .29
(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 |
 With a
chainsaw cut off
the 4 corners
(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 |
 Rotate
the ice & cut off 4 more corners, again use the lines as guides |
 Using a
sharp chisel
Carve 3 hoops around ice |
 Using
the chisel
Remove the 8 humps |
 Using a
Sphere scratchy board
Remove the high spots |
 Scratch
the whole surface
in a circular pattern |
 Using
sand paper
sand the whole surface |
 Spray
with a hose set on gentle. |
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. Steve Brice’s “Make an 18 sided shape” technique.
3. Junichi’s “Finish sculpting with the scratchy board” technique.
