Moisture Mapping is a fundamental aspect of woodworking. Understanding the moisture content of wood is essential for successful turning, ensuring proper drying practices, and preventing deformation or damage during construction.

Wood Moisture Content

Wood moisture content refers to the amount of water present within the wood’s cellular structure. The equilibrium moisture content (EMC) is the moisture level at which wood remains in balance with its surrounding environment.

Wood moisture content can be measured using a moisture meter, which provides a percentage reading. A high moisture content can affect the wood’s properties, making it more susceptible to warping, swelling, and decay.

How Dry Should Wood Be Before Turning?

Determining the ideal moisture content for wood before turning depends on the specific project and the species of wood being used.

• For general turning, wood with a moisture content between 8% and 12% is recommended.
• Hardwoods tend to be turned at a lower moisture content (6% – 8%) to prevent tearing and ensure smoothness.
• Softwoods can be turned at a slightly higher moisture content (10% – 12%) due to their less dense nature.

Properly drying wood before turning reduces the risk of warping, cracking, and other drying-related issues. It also allows the wood to turn more cleanly and accurately. By understanding Moisture Mapping and the importance of wood moisture content, woodworkers can achieve optimal results in their projects.
