Now here is the fun part!

It is time to shape your stock cylinder into an elegant sculpture.

In this step we will use a small exacto knife and a fine sandpaper as the primary cutting tools. When cutting chess peices, the design can be broken down into body parts. - Head, shoulder, waist, feet. It is safest to start with the feature farthest from the faceplate and work your way down. So we will start wit the head. The steps are:

Shape
-Follow the pattern
-Cut largest diameter of first feature
-Cut smallest diameter
-Connect the cuts
-Check against pattern
-Try to fix...
-Sand

-Follow the Pattern
-Start by marking the largest diameter of the sherical head on the top of the cylinder with a marker.

-Cut largest diameter of first feature
-Now cut the entire head portion to this outer diameter. Cut slowly. I like to carefuly cut the very top to the needed diameter, then I cut the rest to match.
-You can use the patterns you cut out to check the size.

-Cut smallest diameter
-Now cut the smallest diameter, mark the vertical location of the smallest diameter and cut a narrow groove to the correct depth at this location.
-Mark the loation of the widest diamter

-Connect the cuts
-Now shape the curves from the smallest to largest diameter. Work slowly and check the pattern.

-Check against pattern
-The final ball should fit neatly into the negative profile you cut earlier.

-Try to fix...
-I am usually off, but try to fix it. Or at least work it into a reasonalbe shape.

-Sand
-Lightly sand the head with a fine grit. You don't want to change the shape, but just smooth the surface.

Congratulations!!! You just finished your first feature!

You will not touch this part again until you paint or seal the finished peice.

The same basic staps can be followed to cut the remaining features.
