About the sound
Pythagoras-Drott’s main line of production in the early 20th century was hot bulb engines. One machine, crucial for the production of these engines, is this horizontal milling machine which was used to shape the inside of the engine housing. The milling process was fairly slow which provided the operator of the machinery the possibility to work on a different drilling or lathing machine simultaneously. In this sound clip the milling machine is carving the inside of a cast iron cylinder. The milling machine was built by the Stockholm based Atlas company, it runs on diesel and is probably over a hundred years old.
