Proof of Concept

Whether the intended outcome is a new sculpture, furniture design or product idea, I often begin the ‘Proof of Concept’ phase with a stroll through the salvage yards. My absolute favorite is Maselli & Sons in Petaluma, CA. With over seven acres of neatly organized machine parts, scrap metal, salvaged tools, motors and hardware, it’s easy to find what you’re looking for, and even easier to find what you had no idea existed but could not do without.

For me, Proof of Concept involves building a working model, with the goal of establishing an idea’s feasibility. Demonstrating Proof of Concept, however schematic in form, makes it much easier to proceed with cost estimates and material requirements, the next steps in planning a production when collaborating with fabricators and engineers. It also often leads to a better idea or technique than originally conceived.

For Spinnradl, I need to prove that a hand-cranked, acoustic music box will produce a decent sound when rendered on a monumental scale. Once I know the components that produce the sound, it’s relatively straightforward to make a repeating melody. For my first experiment I found parts to make a large scale, tuned ‘comb’ of hardened steel, like a giant kalimba. Next I’ll play with how best to amplify the sound by making an integral resonating box.
