A steam-powered sawmill was built in London, England in 1663. Sawyers who feared unemployment, rioted at its introduction.
James Hall Nasmyth (sometimes spelled Naesmyth, Nasmith, or Nesmyth) (19 August 1808 – 7 May 1890) was a Scottish engineer, artist and inventor famous for his development of the steam hammer. Continue reading

Paul-Louis Toussaint Heroult created the Electric Arc Furnace (Heated by a carbon arc at very high temp.) in France. At first it was used to melt scrap iron, then later in the Hall-Heroult process, the electrolytic refinement process of aluminum.

- Electric arc furnace – Wikipedia
ndustrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.
- When was the electric arc furnace invented?
The German-born British inventor Sir William Siemens first demonstrated the arc furnace in 1879 at the Paris Exposition by melting iron in crucibles. In this furnace, horizontally placed carbon electrodes produced an electric arc above the container of metal.
- What does electric arc furnace do?
Steel scrap (or other ferrous material) is first tipped into the EAF from an overhead crane. A lid is then swung into position over the furnace. This lid contains electrodes which are lowered into the furnace. An electric current is passed through the electrodes to form an arc.
- Steel History From Iron Age to Electric Arc Furnaces – The Balance
The development of steel can be traced back 4000 years to the beginning of the Iron Age. Proving to be harder and stronger than bronze, which had previously been the most widely used metal, iron began to displace bronze in weaponry and tools.
- Electric Arc Furnace | Industrial Efficiency Technology & Measures
Electric Arc Furnaces (EAFs) are a central part of the production route that is an alternative to the dominant BF-BOF route. EAFs are used to produce carbon steels and alloy steels primarily by recycling ferrous scrap.
Gallic born latin poet by the name of Decimus Magnus Ausonious, described a stone cutting water powered mill in his lyric poem about the Mosella (Moselle) river in Gaul (now France), written circa 360. This water powered mill was cutting marble for the city of Treves. Mills of this type may have been used throughout the roman empire for several hundred years.

- Hierapolis sawmill – Wikipedia
The Hierapolis sawmill is believed to be a Roman water-powered stone sawmill at Hierapolis, Asia Minor (modern-day Turkey). Dating to the second half of the 3rd century AD, the sawmill is considered the earliest known machine to combine a crank with a connecting rod, although neither clear ancient scripts nor engineering drawings were yet found to support this theory.
- Sawmill – Wikipedia
A sawmill or lumber mill is a facility where logs are cut into lumber. Before the invention of the sawmill, boards were made in various manual ways, either rived (split) and planed, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below.
- Roman Mills (Article) – Ancient History Encyclopedia
The Romans constructed mills for use in agriculture, mining and construction. Around the 3rd century BCE, the first mills were used to grind grain.

Showing a picture of the Villard saw (ill. 1) he described it as the earliest drawing we had of a semi-automatic tool (alluding to the feed back mechanism which advanced the timber to the blade) but not the earliest known such saw, one being recorded at Evreux in 1204.
