Wood Moisture Content
Moisture Mapping is a crucial technique in woodworking that determines the moisture content in wood. This measurement is essential for ensuring the stability, durability, and usability of wooden objects. Wood that is too moist or too dry can warp, crack, or split, leading to project failures.
How Dry Should Wood Be Before Turning?
The ideal moisture content for wood prior to turning depends on the intended use of the finished product.
- Furniture and Interior Use: 6-8% moisture content
- Exterior Use: 12-15% moisture content
Lower moisture content ensures minimal movement, stability, and resistance to cracking. Higher moisture content provides flexibility and reduces the risk of splintering during turning.
Determining Dryness Using Moisture Mapping
Moisture Mapping uses specialized meters to non-destructively measure wood moisture content. Proper technique involves:
- Inserting the meter pins into the wood at various depths
- Recording readings in multiple locations
- Averaging the results to obtain an accurate moisture content value
By carefully controlling the moisture content of wood before turning, woodworkers can ensure the success of their projects.
