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 ...
A method for logs 16–19 in (41–48 cm) A method for logs over 19 in (48 cm) Quarter sawing or quartersawing is a woodworking process that produces quarter-sawn or quarter-cut boards in the rip cutting of logs into lumber. The resulting lumber can also be called radially-sawn or simply quartered.
A "full deck" of logs awaiting the mill. A log pond is a small natural lake or reservoir used for storage of wooden logs in readiness for milling at a sawmill.Although some mill ponds served this purpose for water-powered sawmills, steam-powered sawmills used log ponds for transportation of logs near the mill; and did not require the elevation drop of watermill reservoirs.
Re-sawing is the splitting of 1-to-12-inch (25–305 mm) hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a 10-foot-long (3.0 m) 2×4 ( 1 + 1 ⁄ 2 by 3 + 1 ⁄ 2 in or 38 by 89 mm) into two 1×4s ( 3 ⁄ 4 by 3 + 1 ⁄ 2 in or 19 by 89 mm) of the same length is considered re-sawing.
Today, head saws are mostly used for cutting logs 16 to 72 inches (0.41 to 1.83 m) in diameter depending upon the type of band mill the saws are mounted on. More optimized machines now cut the smaller diameters since they are far more efficient and can provide greater production.
There the logs were decked onto "rollways." In spring when snow thawed and water levels rose, the logs were rolled into the river, and the drive commenced. [6] To ensure that logs drifted freely along the river, men called "log drivers" or "river pigs" were needed to guide the logs. The drivers typically divided into two groups.
