Betelgeuse marks my first kinetic sculpture that combines metallics with vibrant color, offering a truly captivating visual and mechanical experience. At the core of its design, multiple pulleys guide a single serpentine belt, which not only powers the movement but also sparks the viewer's curiosity. This intricate system of pulleys amplifies the mechanical intrigue, allowing anyone who watches it to become captivated by how the parts interact and work together.
The two pattern wheels at the heart of Betelgeuse are cladded in polymer-coated aluminum, creating a vibrant and reflective surface. This effect is far more striking than what stained wood could achieve, adding layers of depth and shine to the motion of the sculpture. The primary material used throughout the sculpture is imported laminated Baltic birch, a strong and beautiful wood that provides both durability and an elegant finish.
In terms of the drive mechanism, I’ve opted for polished brass pins in place of simple wooden ratchet wheels. This choice not only enhances the aesthetic with a touch of luxury but also ensures the sculpture's reliability and longevity. Betelgeuse is propelled by a stainless steel constant force spring, which provides consistent energy to the pattern wheels through a steel spring belt. Unlike rubber belts that degrade over time, the steel spring belt maintains its elasticity, guaranteeing smooth motion and longer-lasting performance.
To get the sculpture moving, the spring is wound manually by placing an index finger next to one of the spokes of the lower right pulley and turning it counterclockwise for about 22 turns. Once the drive pulley is released, the sculpture gets its first "push" from the spring, which lasts just under two seconds. After that initial burst, the spring is not needed again until either of the pattern wheels slows enough to start rotating backward.
The two pattern wheels are completely independent, spinning in opposite directions. When one wheel starts to rotate backward, a clock-like escape mechanism is triggered, giving the spring another opportunity to impart a burst of energy to keep the wheel spinning. This cycle continues for around 7 to 8 hours, creating a constant, mesmerizing movement that fascinates anyone who watches.
With its intricate mechanics and stunning visuals, Betelgeuse is a sculpture that captures the imagination and engages viewers with every spin.
The two-tone coloring scheme for the pattern wheels can be customized.
