What is proper technique for nailing two pieces of wood together?

Pre-drilling holes before nailing is a proper technique for joining two pieces of wood together, especially in specific applications where precision and structural integrity are important. This technique helps to prevent the wood from splitting, which can occur when a nail is driven directly into the grain, particularly with hardwoods or at the edges of the wood pieces.

By creating a pilot hole, you also ensure that the nail is more likely to go in straight and achieve the desired holding power. Pre-drilling can also allow for better alignment of the pieces being joined, as it provides a guide for the nail to follow. This method is especially useful when working with thicker pieces of wood or when using larger nails that require more force to drive in. The result is a neater finish and a stronger joint, making it an essential technique in carpentry.
