Understanding Wane in Timber: Types, Causes, and Effects
Wane is a term used in the timber industry to describe the reduction of the diameter of a log or timber after it has been cut and processed. The wane can be caused by various factors, including the way the tree was harvested, the type of sawing or cutting tool used, and the drying process.
Wane can be classified into two main types:
1. Natural wane: This occurs when the tree grows in a way that creates a natural taper, resulting in a smaller diameter at the top of the tree than at the base.
2. Artificial wane: This is caused by human intervention during the logging or processing stage, such as when the log is cut with a saw or other cutting tool.
Wane can have both positive and negative effects on the quality and value of the timber. On the one hand, some types of wane can make the timber more prone to warping or cracking, which can reduce its structural integrity and value. On the other hand, certain types of wane can also create unique aesthetic features that are prized by woodworkers and craftsmen, such as the "bird's eye" pattern found in some types of maple or walnut.
In summary, wane is a term used to describe the reduction of the diameter of a log or timber after it has been cut and processed, and it can have both positive and negative effects on the quality and value of the timber depending on the type and extent of the wane.
