The "high iron" saw is the museums's biggest machine: 12m length, 3 m height. She's going to cut up a plank in front of you, as she'd been making it from the beginning of the 20th century to the 70th years. That means: conscientiously and without hurry up: with a speed of 1 to 2 meters by minute, depending on the wood density, the log's diameter, and the rate of water flow, because it was powered by hydrolic energy.

"It needs the needed time" said the ancients. "While the log sawing up, the worker had time to smoke a cigarette. The machine stopped by itself, than the worker was notified by the sudden silence."
