Joints should be oriented as close as possible to what?

Joints should be oriented as close as possible to parallel to the grain in wood construction and aviation applications. When the joints are aligned with the grain direction, the structural integrity and load-bearing capacity of the wood are maximized. Wood has a unique grain structure that influences its strength; it is generally stronger along the grain than across it. By aligning joints parallel to the grain, you ensure that the load is distributed more evenly along the fibers, thereby minimizing the risk of splitting or failure under stress.

Greater strength and durability are achieved because the natural characteristics of the wood are respected. This orientation also helps in maintaining the structural efficacy of wood components subjected to various forces, such as tension or compression, allowing for optimum performance in aviation applications.
