Spinning Sound Paths explores processes of bespoke tool-making with wooden moulds used to make spinning horn-shaped components from circular blanks. The spinning moulds were made by CNC milling, a collection of these components were brazed together to make horn-shaped ends that were connected by tubing formed through bending and tube expansion processes.
Although the spinning process leads to initial work-hardening of the metal which makes it prone to tearing, heat annealing has been applied to soften the metal sufficiently to allow further spinning that achieves the desired form. The process of forming required developing tacit knowledge of the metal hardening process, this was acquired through testing a range of forming materials including mild steel, aluminium and copper. Copper was finally selected for its malleability and finish.
