  • 11:0211:02, 16 March 2023 diff hist +253‎ N Wane ‎ Created page with "Wane refers to the presence of bark or the absence of wood on the edge of the board. This can occur when the board is cut from a portion of the tree where the bark or outer layer of wood is present, or where the edge of the board is irregular or uneven." current
  • 10:5210:52, 16 March 2023 diff hist +997‎ N Decay ‎ Created page with "Decay in lumber refers to the breakdown of the wood caused by fungi or other microorganisms. Decay typically occurs in moist conditions, where the wood is exposed to high levels of moisture and is unable to dry out properly. This can be caused by exposure to rain or groundwater, or by high levels of humidity in the air. The fungi that cause decay feed on the wood and break down its cellulose and lignin, which are the primary structural components of the wood. This can w..." current
  • 10:5110:51, 16 March 2023 diff hist +400‎ N Check ‎ Created page with "A check is a crack that occurs in the wood, typically running along the growth rings of the tree. It is caused by the wood drying out and shrinking unevenly, resulting in the wood splitting. Checks can occur at any point in the wood, but are most commonly found on the ends of the board. Checks can weaken the structural integrity of the wood and make it more prone to breaking or splitting further." current
  • 10:4910:49, 16 March 2023 diff hist +392‎ N End Splits ‎ Created page with "End splits are cracks that occur at the ends of the wood. They typically start at the end of the board and extend inward, following the grain of the wood. End splits can occur as a result of stresses in the wood caused by uneven drying or changes in temperature and humidity. End splits can weaken the structural integrity of the wood and make it more prone to breaking or splitting further." current
  • 10:4610:46, 16 March 2023 diff hist +816‎ N Shake ‎ Created page with "Shakes are separation or cracks in the wood that occur along the grain, running parallel to the tree's growth rings. There are two types of shakes: radial shakes and tangential shakes. Radial shakes occur along the radius of the tree and are caused by stresses in the tree resulting from wind or uneven growth. They typically appear as thin, irregular cracks in the wood. Tangential shakes occur perpendicular to the radius of the tree and are caused by stresses in the tre..." current
  • 10:3510:35, 16 March 2023 diff hist +626‎ N Overgrowth of Injury ‎ Created page with "Overgrowth of injury is a natural response of the tree to injury or damage. When a tree is injured, it responds by producing new wood around the damaged area in an attempt to repair itself. This new wood growth can appear as a raised or swollen area on the trunk or branch of the tree and is known as overgrowth of injury. In lumber, overgrowth of injury can manifest as a raised or irregular area on the surface of the wood. This feature can be caused by a variety of facto..." current
  • 10:3410:34, 16 March 2023 diff hist +398‎ N Bark Pocket ‎ Created page with "Bark pockets in lumber are areas where bark has become incorporated into the wood during the growth of the tree. These pockets can appear as small or large voids in the wood and may be irregularly shaped. Bark pockets can also impact the structural integrity and stability of the wood. If the pockets are large or numerous, they may weaken the wood and make it more prone to cracking or splitting." current
  • 10:3210:32, 16 March 2023 diff hist +462‎ N Resin Pocket ‎ Created page with "Resin pockets are areas where resin has accumulated in a concentrated area within the wood. These pockets can vary in size and shape, and may appear as small, isolated dots or as larger, irregularly shaped areas in the wood. Resin pockets are most commonly found in softwood species, such as pine and spruce, and are a natural feature of the wood. They are formed when the tree produces excess resin in response to injury, such as insect infestation or disease." current
  • 10:2710:27, 16 March 2023 diff hist +646‎ N Resin Streaks ‎ Created page with "Resin streaks in lumber are similar to resin veins, in that they are a natural feature of some species of trees and are caused by the production of resin to protect the tree from damage. Resin streaks are typically larger and more concentrated than resin veins, and may appear as darker, thicker lines or blotches in the wood. Resin streaks are most commonly found in softwood species, such as pine and fir, and can vary in size, shape, and color depending on the specific s..." current
  • 10:2010:20, 16 March 2023 diff hist +412‎ N Resin Veins ‎ Created page with "Resin veins in lumber are a natural feature of some species of trees, such as pine and fir. These veins are formed when the tree produces resin to protect itself against damage, such as insect infestation or disease. Resin veins are typically visible as thin, dark lines that run parallel to the grain of the wood. They may appear as individual lines or as a network of interconnected lines throughout the wood." current
  • 10:1310:13, 16 March 2023 diff hist +722‎ N Heart Shakes ‎ Created page with "Heart shakes in lumber refer to cracks or separations that occur along the growth rings of a tree, typically near the center of the trunk where the heartwood is located. These types of cracks are also known as radial shakes, as they run radially along the tree trunk. Heart shakes are caused by natural stresses that occur within the tree as it grows and ages, such as changes in temperature, moisture, or wind load. These stresses can cause the wood fibers to separate or c..." current
  • 10:0410:04, 16 March 2023 diff hist +789‎ N Pith ‎ Created page with "Pith in lumber refers to the central core of a tree trunk, which is comprised of soft, spongy tissue that contains cells that are still alive. When a tree is cut down and sawn into lumber, the pith is typically found near the center of the log and may be visible as a small, circular or oval-shaped area in the center of the cut lumber. The pith is typically softer and less dense than the surrounding wood, and may be more susceptible to cracking, warping, or other forms o..." current
  • 10:0210:02, 16 March 2023 diff hist +563‎ N Borer Hole ‎ Created page with "A borer hole in lumber refers to a small, round hole that is made by a wood-boring insect, such as a beetle or a moth, as it tunnels through the wood. Borer holes can be found in both softwood and hardwood lumber and can vary in size depending on the size of the insect that created them. The presence of borer holes in lumber can be a cause for concern, as they may indicate the presence of an active infestation of wood-boring insects. These insects can cause significant..." current
  • 09:5909:59, 16 March 2023 diff hist +665‎ N Cone Hole ‎ Created page with "A cone hole in lumber refers to a small, circular hole that is typically found in softwood lumber, such as pine, spruce, or fir. The hole is caused by the presence of a small, cone-shaped projection on the tree, which falls off or is removed during the milling process. Cone holes are usually small in size, typically less than an inch in diameter. They are often located near the edge of the board and may be difficult to see if the lumber has been planed or sanded. While..."
  • 09:5809:58, 16 March 2023 diff hist +451‎ N Knot Hole ‎ Created page with "A knot hole refers to a hole or void in the wood that is caused by a knot in the tree where a branch or limb grew. When a tree is cut down and sawn into lumber, the knots in the wood can leave behind holes or voids where the branch or limb once was. Knot holes can vary in size and shape, depending on the size and position of the knot in the tree. Some knot holes may be relatively small and round, while others may be larger and irregularly shaped."
  • 09:5709:57, 16 March 2023 diff hist +222‎ N Termite Gallery ‎ Created page with "A termite gallery in lumber refers to a tunnel or channel that has been excavated by termites within the wood. When termites infest lumber, they create galleries or tunnels within the wood as they feed and move through it." current
  • 09:5309:53, 16 March 2023 diff hist +781‎ N Occluded Branch Stub ‎ Created page with "In lumber, occlusion refers to a process by which the wood fibers around a branch or other defect grow together and close off the defect. When a branch is cut or otherwise removed from a tree, the tree responds by growing new wood around the site of the injury. If the new wood grows tightly around the defect, it can eventually close off the opening and create a smooth, continuous surface in the wood. Occlusion is a natural process that can occur in both hardwood and sof..." current
  • 09:3209:32, 16 March 2023 diff hist +561‎ N Loose Knot ‎ Created page with "A loose knot refers to a knot in wood that is not tightly embedded or firmly attached to the surrounding wood fibers. When wood is cut from a tree, knots can form where branches grew from the trunk or where two parts of the trunk grew together. Loose knots are generally darker and have shrunk away and detached from the surrounding wood during the growing process. They contain visible cracks or gaps and are often surrounded by a thin layer of scar tissue called callus...."
