Inner Science

Images of cascading machine oil and glittering metal form focal points in this landscape of gears, grinding as they are whittled down to size. Inner Science’s new track is a perfect match for the almost other worldly scene. The listener is able to enjoy the space created in the gaps between the reverberating clanging sounds of metal. This ambient track highlights the tension and release that is part of the inherent beauty of the factory.

  • In the manufacture of large metal gears, oil is constantly applied while the gear is slowly carved into shape. The gold piece is not itself a gear, but a blade. As the gear spins, the blade cuts, bit by bit, until the gear reaches the desired shape.

  • The creation of a plastic gear. The spinning object above is the product, the one below is the blade. A they both spin, a groove is gradually cut into the gear.

  • Gears with cogs on the inside are creating through the raising and lowering of a cutting implement. The large metal cylinder visible here is the product, and the component moving up and down is the blade being used to shape it.

  • The finished gears have a wide variety of applications. The gear in this picture seems to be a part of the mechanism used in an automatic door.
