The quarter sawing is process for rip cutting logs into lumber. It produces quarter-sawn or quarter-cut boards. The resulting lumber can also be called radially-sawn or simply quartered. Wood cut in this way is prized for certain applications, but it will tend to be more expensive as well.
Tonewood choices vary greatly among different instrument types. Guitar makers generally favor quartersawn wood because it provides added stiffness and dimensional stability. Soft woods, like spruce, may be split rather than sawn into boards so the board surface follows the grain as much as possible, thus limiting run-out. This is especially ...
The types of rip-cuts influence the quality of the lumber. Plain-sawn is the most common type of cut where a log is repeatedly run through a saw and much of the lumber has wood grain nearly parallel to the width of the boards. Quarter sawn and rift-sawn wood is more time consuming and wasteful to produce but is of higher quality.
Picea sitchensis, the Sitka spruce, is a large, coniferous, evergreen tree growing to just over 100 meters (330 ft) tall, [2] with a trunk diameter at breast height that can exceed 5 m (16 ft).
Bentham was a British naval engineer with many shipbuilding inventions to his credit. Veneers at the time of Bentham were flat sawn, rift sawn or quarter sawn; i.e. cut along or across the log manually in different angles to the grain and thus limited in width and length. [citation needed]
The Spruce Production Division was a unit of the United States Army established in 1917 to produce high-quality Sitka spruce timber and other wood products needed to make aircraft for the United States' efforts in World War I. The division was part of the Army Signal Corps's Aviation Section.
The process of manufacturing at the Sitka Pulp Mill consisted of utilizing about 70 percent of Western Hemlock and 30 percent Sitka Spruce. The mill was able to debark logs as large as 1.8 meters in diameter and 7.2 meters in length. The warehouse and dock were able to accommodate 17,000 tons of baled pulp.
Drying time is inversely related to thickness and, to some extent, the width of the lumber. Whether the lumber boards are quarter-sawn, flat-sawn, or bastard-sawn (mixed-sawn) Sawing pattern influences the distortion due to shrinkage anisotropy. Permissible drying degrade Aggressive drying schedules can cause timber to crack and distort.
