On the right is the original sculpture. The bird and cadge are two separate models and were the guides for a three dimensional pantograph which cut the steel moulds that made the music box on the left. All I had to go by were the designers hand sketched concepts.

This model has 1/4" walls, and was used for sand casting.

These two patterns were used to create roto molds.

This simple pattern was made with styrofoam and masking tape.

The lower middle section of this model was a fiberglass layup formed over the above pattern.
