What is a spring in the timber?

A spring in timber refers to a natural feature in the wood where the growth rings are unevenly distributed, causing the wood to curve or twist. This can occur due to variations in moisture, sunlight, or soil conditions during the tree's growth. Springs can affect the structural integrity and appearance of the timber, making it more challenging to work with in construction or woodworking projects. Properly identifying and managing springs is crucial for ensuring the quality of the final product.
