A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the ...
Portable sawmills are sawmills small enough to be moved easily and set up in the field. They have existed for over 100 years but grew in popularity in the United States starting in the 1970s, when the 1973 oil crisis and the back-to-the-land movement had led to renewed interest in small woodlots and in self-sufficiency .

Log driving is a means of moving logs (sawn tree trunks) from a forest to sawmills and pulp mills downstream using the current of a river. It was the main transportation method of the early logging industry in Europe and North America .
In the 1870s, the limitation of log size due to the radius of the circular saw was improved with the introduction of the double circular saw- with one blade atop the other. In the 1880s, the band saw was introduced and was able to allow the head saw to handle logs of nearly unlimited size, ideal for the Californian redwoods .
Pacific Lumber Company built flatcars from wood and maintained a fleet of locomotives for moving logs from the woods into the mill and for switching cars for loading or unloading at the sawmill. Diesels replaced steam locomotives in 1955. [25] Log trains of wooden flat cars ran to the Scotia mill until 1976 from a log deck in Carlotta ...
