Overview

Bobby Winkles, March 11, 1930 – April 17, 2020, head coach of the Arizona State University Sun Devils (1959-1971). ⁠

Originally created in clay, this sculpture weighs about 250 pounds and sits in the Phoenix Municipal Stadium and honors the man known as the architect of ASU baseball.⁠ ⁠

Goals

Local artist Jeff Davenport worked on this sculpture of baseball player and acclaimed ASU coach Bobby Winkles. We were able to enlarge this from a maquette Jeff provided for us which she then sculpted the details back in at this scale.

Process

The Bobby Winkles sculpture is cast in bronze and weighs about 250 pounds. It was created
using the age-old process called “Lost Wax Casting.” The original sculpture was created as a
clay maquette or small model. Once the maquette was created and approved, the foam
enlargement was made with digital technology and cut with a laser to replicate the model at a larger scale. The foam enlargement was then covered with clay and the artist again re-sculpted the final details.

From that point a rubber mold was created. Once the rubber mold was removed from the
enlargement, the mold was used to create wax patterns. These patterns were used to create new molds made out of a ceramic shell material. From there the wax is burned out of these ceramic shells, and molten bronze was poured into those hollow molds. After the bronze cooled, the mold material was blasted off to reveal the workable bronze patterns. Those patterns are sandblasted, and welded together to recreate the surface of the enlarged sculpture. The final process is to sandblast and heat the bronze before the application of the patina which gives the sculpture its rich, beautiful color and depth.
