Typically, grooves are used to house the panels in frame and panel construction and the bottoms of drawers. For more structural construction, grooves are created along the sides and/or ends of panels, such as in tongue and groove construction. [2] Applications include roofing, siding and flooring.
Then there are the cutting-edge materials — wrapped in jargon like "cementitious fiber-reinforced composite building system" — that offer alternatives to the flammable lumber that dominates ...
Normally, the desired outcome of jointing is an edge which is straight along its length and perpendicular to the face of the board. However, there is another technique often used when gluing up panels, referred to as a sprung joint. [1] In this technique, the desired outcome is an edge which is slightly concave along its length.
A birds-mouth joint in a rafter, set upon a double top plate. Shown are the two cuts of the joint: the seat cut and the heel cut. In light frame construction, a birdsmouth joint or bird's beak cut is a woodworking joint that is generally used to connect a roof rafter to the top plate of a supporting wall. [1]
The effect of wood shrinkage is concealed when the joint is beaded or otherwise moulded. [1] In expensive cabinet work, glued dovetail and multiple tongue and groove are used. Each piece has a slot (the groove or dado) cut all along one edge, and a thin, deep ridge (the tongue) on the opposite edge. The tongue projects a little less than the ...
Each piece has a groove cut all along one edge, and a thin, deep ridge (the tongue) on the opposite edge. If the tongue is unattached, it is considered a spline joint. Birdsmouth joint: Also called a bird's beak cut, this joint used in roof construction. A V-shaped cut in the rafter connects the rafter to the wall-plate. [11] Cross lap

Scribe joinery is also commonly used in the building of log homes. The shape of the log underneath is scribed into the bottom of a log to be placed on top.
Self-tapping pocket screws are used for pocket hole joints. Pocket screws are generally more expensive, but they are needed for a tight, strong joint. Pocket screws have a wide washer head to spread the load for a firm bond, and prevent screwing too far into the joint and cracking the wood.
