perhaps the most important physical aspect of wood grain in woodworking is the grain direction or slope e.g. against the grain . the two basic categories of grain are strht and cross grain. the two basic categories of grain are strht and cross grain.
many wood joinery techniques either depend upon or compensate for the fact that wood is anisotropic: its material properties are different along different dimensions. this must be taken into account when joining wood parts together, otherwise the joint is destined to fail. gluing boards with the grain running perpendicular to each other is .
an interlocking is designed so that it is impossible to display a signal to proceed unless the route to be used is proven safe. in north america, the official railroad definition of interlocking is: 'an arrangement of signals and signal appliances so interconnected that their movements must succeed each other in proper sequence'.
the top of the branch collar consists of dense interlocking wood grain, which provides mechanical support to the branch attachment. branch collars can also be flat or somewhat recessed into the trunk or parent branch, as in some conifers. the collar consists primarily of tissues connected directly to the tree's main trunk or stem,.
a cut made perpendicular to the wood grain. crown of thorns a system of self-supporting and interlocking pieces. cruck a pair of crooked, structural timbers in a timber frame building. crucks act as both posts and rafters like an a-frame. cup transverse bending, convex or concave, usually predictable, considering grain orientation. see wood warping. d
butcher block, butcher's block is a style of assembled wood often hard maple, teak, birch, or walnut used as heavy duty chopping blocks, table tops, and cutting boards. it was commonly used in butcher shops and meat processing plants but has now become popular in home use. there are two basic styles of butcher block: end grain and edge grain.
oriented strand board is manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and synthetic resin adhesives 95% wood, 5% wax and resin .
joinery is a part of woodworking that involves joining together pieces of wood or lumber, to produce more complex items. some wood joints employ fasteners, bindings, or adhesives, while others use only wood elements. the characteristics of wooden joints - strength, flexibility, toughness, appearance, etc.
the sliding dovetail is a method of joining two boards at right angles, where the intersection occurs within the field of one of the boards, that is not at the end. this joint provides the interlocking strength of a dovetail. sliding dovetails are assembled by sliding the tail into the socket. it is common to slightly taper the socket, making .
elm wood is valued for its interlocking grain, and consequent resistance to splitting, with significant uses in wagon wheel hubs, chair seats and coffins. the bodies of japanese taiko drums are often cut from the wood of old elm trees, as the wood's resistance to splitting is highly desired for nailing the skins to them, and a set of three or more is often cut from the same tree. the elm's .
the sapwood has an interlocking grain. in temperate climates, the wood is very durable against fungi, and durable against dry wood borers and termites. it is suitable for use in a marine environment. bilinga may be used for railway sleepers, poles, hydraulic works, bridges and ship planking and flooring. it may also be used for heavy industrial .
oriented strand board osb is a type of engineered wood similar to particle board, formed by adding adhesives and then compressing layers of wood strands flakes in specific orientations. it was invented by armin elmendorf in california in 1963.
hence wainscot or wainscoting became a panelling style applied to the lower 90 to 150 cm 3 to 5 ft of an interior wall, below the dado rail or chair rail, and above the baseboard or skirting board. citation needed it is traditionally constructed from tongue-and-groove boards, though bead-board or decorative panels, such as a wooden door might have, are also common.
working perpendicular to the wood grain. crosscut a cut made perpendicular to the wood grain. crown of thorns a system of self-supporting and interlocking pieces. cruck a pair of crooked, structural timbers in a timber frame building. crucks act as both posts and rafters like an a-frame. cup
a branch attachment is where a branch is attached to the trunk of a tree. three types of branch attachment are recognized due to differences in the anatomical position of buds that form them. two key components contribute to the mechanical strength and toughness of the attachment: interlocking wood grain at the top of the attachment and an embedded knot that often lies within the attachment. a common malformation of a branch attachment is the inclusion of bark within the join, which can weaken t
like other woods with interlocking grain, planes should be kept extra sharp to prevent tearing at the grain margins. it steam-bends easily, holds screws well but pilot holes and countersinking are needed. it tends to be a 'lively' wood, tending to warp and distort while drying. this water resistant wood easily takes most finishes and stains.
mineral bonded wood wool boards ww boards are building boards made of wood wool fibres, water and the binding agents cement, caustic magnesia and gypsum. mineral bound wood wool boards are used in a wide range of applications, e.g., thermal insulation, acoustic insulation, indoor decoration, etc.
