Lumber is wood that has been processed into uniform and useful sizes, including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing. Lumber has many uses beyond home building. Lumber is sometimes referred to as timber in the United Kingdom, Europe, Australia, and New Zealand, while in other parts of the world the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut.
A circular saw or a buzz saw, is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor. A hole saw and ring saw also use a rotary motion but are different from a circular saw. Circular saws may also be loosely used for the blade itself. Circular saws were invented in the late 18th century and were in common use in sawmills in the United States by the middle of the 19th century.
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws.
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. Their popularity has grown exponentially since 1982, when the portable bandsaw mill was first commercialized.
In woodworking, a rip-cut is a type of cut that severs or divides a piece of wood parallel to the grain. The other typical type of cut is a cross-cut, a cut perpendicular to the grain. Unlike cross-cutting, which shears the wood fibers, a rip saw works more like a series of chisels, lifting off small splinters of wood. The nature of the wood grain requires the shape of the saw teeth to be different thus the need for both rip saws and crosscut saws; however some circular saw blades are combination blades and can make both types of cuts. A rip cut is the fundamental type of cut made at a sawmill.
A sawmill 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. The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig, with similar horizontal operation.
A bandsaw is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw. The minimum radius of a curve is determined by the width of the band and its kerf. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of sizes and tooth pitches, which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic.
Norske Skog Saugbrugs AS is a pulp mill and paper mill located in Halden, Norway, which produces supercalender (SC) magazine paper. Located in the river Tista in Tistedalen, the mill produces 550,000 tonnes per year in three paper machines. Pulp is produced both from virgin fibers at an on-site thermomechanical pulp (TMP) mill. Part of Norske Skog, it is the sole remaining magazine mill in Norway.
A head saw, framesaw, gang saw or head rig is the saw that makes the initial cuts in a log at a sawmill, turning a log into cants, or planks of wood.

A chainsaw mill or PortaMill or Logosol sawmill is a type of sawmill incorporating a chainsaw, that is used by one or two operators to mill logs into lumber for use in furniture, construction and other uses. Although often used as a generic term, Alaskan Mill is a registered trademark of Granberg International.

The Ottawa River timber trade, also known as the Ottawa Valley timber trade or Ottawa River lumber trade, was the nineteenth century production of wood products by Canada on areas of the Ottawa River and the regions of the Ottawa Valley and western Quebec, destined for British and American markets. It was the major industry of the historical colonies of Upper Canada and Lower Canada and it created an entrepreneur known as a lumber baron. The trade in squared timber and later sawed lumber led to population growth and prosperity to communities in the Ottawa Valley, especially the city of Bytown. The product was chiefly red and white pine.The Ottawa River being conveniently located with access via the St. Lawrence River, was a valuable region due to its great pine forests surpassing any others nearby. The industry lasted until around 1900 as both markets and supplies decreased, it was then reoriented to the production of wood pulp which continued until the late 1990s and early 2000s.
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.
A swingblade sawmill utilizes a single circular sawblade which pivots about a 90 degree point, to saw in both vertical and horizontal planes. The single blade travels horizontally in one direction down the log, and returns in vertical position, thus removing a sawn piece of timber. The swingblade head unit is normally mounted on a moving frame that travels along a track or tracks, up and down a stationary log.
Flat sawing, flitch sawing or plain sawing is a woodworking process that produces flat-cut or plain-cut boards of lumber.
Brooks-Scanlon Lumber Company was a lumber products company with large sawmills and significant land holdings in Minnesota, Florida, British Columbia, and Central Oregon. The company was formed in 1901 with its headquarters in Minneapolis, Minnesota. Beginning in 1915, its main lumber production facility was in Bend, Oregon. For many years, its Bend sawmill was one of the largest lumber producers in the world. In 1969, the company created Brooks Resources to broaden its business base beyond timber production. Brooks-Scanlon's Bend sawmill was closed in 1994. Today, Brooks Resources is the only vestige of the company that is still in business.
