Watch a lacquer master being cut by a lathe from 1958—and see how the oldest stage of vinyl production still operates today.
Most of us know vinyl LPs and the stamping process that presses hot PVC into a groove. But Technostalgism takes us back to the very start, offering a close-up look at how a lacquer master is cut by a dedicated recording lathe. These lacquer masters, the precursors to final vinyl, are still produced by a Japanese company and look like glossy, near-coat-now-nail-polish surfaces on precision aluminum discs with a lacquer coating—and, yes, they reportedly carry a fresh-paint smell.
The cutting process has remained remarkably consistent for decades, even as the surrounding equipment becomes more modern. In the video below, you’ll get a full tour of the setup and watch a Neumann AM32B Master Stereo Disk Recording Lathe from 1958 carve the single unbroken groove that defines a side of a record.
The cutting tip itself is a stylus whose motion blends the left and right channels and is heated to produce the smoothest possible cuts. The result is so clean, clear, and high-quality that it leaves Technostalgism impressed. Yet there’s more to the story than the tool: the entire workflow, including the spaces between tracks, is the product of meticulous planning and precise coordination.
This article makes it clear that cutting a disk isn’t just about a single instrument; it requires specialized equipment, substantial craftsmanship, and a depth of experience.
