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 ...
Video of a portable sawmill being powered by a traction engine. Arguably, as once used in early Canadian forest logging, the donkey engine was one of the earliest portable sawmills. It was used to winch and haul log booms across lakes and water, then winch itself across land or water to its next site, and finally it would be reconfigured to run ...

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 .
The Great Southern Lumber Company sawmill was designed to process 1,000,000 board feet (2,400 m 3) of lumber per day and was the largest sawmill in the world, [4] spread over 160 acres (65 ha). [7] Once pines were felled, logs were dragged to railroad spurs by rail-mounted steam skidders with 1000-ft (300-m) draglines, loaded onto flatcars ...
Detail how the cutter moulds the beam. A log house moulder is a machine used to shape logs for building a log home.Shaping creates the correct profile for stacking and joining logs.
The modern-day circular saw was invented around the end of the 18th century as a rip-saw to convert logs into lumber in sawmills and various claims have been made as to who invented it. Before the design was invented, logs were sawn by hand using a pit saw or using powered saws in a sawmill using an up-and-down saw with a reciprocating motion ...
Each blade was set at a fixed width meaning each log was cut identically, regardless of flaws. This design was not energy efficient and around 1860 sawmills began to adopt the more efficient circular saw. 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 ...
