Mark Frank | Astro-skeleton, cutting a dial hand @MarkFrankclocks | Uploaded 3 years ago | Updated May 12 2024
Here a dial hand is being cut from a steel blank using a CAD-CAM wire spark-erosion machine. If one looks closely at the steel blank it is actually a hacksaw blade. It turns out that the steel these blades are made from will blue up beautifully in the oven. For more detail go to: http://www.my-time-machines.net/astro_01-21.htm .
