Wood Moisture Content
Wood moisture content (MC) plays a crucial role in the quality of woodturning projects. Moist wood can warp, crack, or split while being worked on, leading to unsatisfactory results. It is essential to determine the optimal moisture content for your specific woodturning project to ensure a successful outcome.
How Dry Should Wood Be Before Turning?
The ideal wood moisture content for turning varies depending on the species and the intended use. As a general rule of thumb, most hardwoods should be between 6% and 8% MC for best results. Softwoods, on the other hand, can be turned at slightly higher moisture contents.
- **Hardwoods:** 6-8% MC
- **Softwoods:** 8-12% MC
Determining Wood Moisture Content
Moisture mapping is a technique used to assess the moisture content of wood. It involves using a moisture meter to measure the electrical resistance of the wood. The resistance is inversely proportional to the moisture content, so a higher resistance indicates drier wood.
Moisture Mapping Process
1. Select a moisture meter: Choose a moisture meter that is calibrated for the wood species you are working with.
2. Calibrate the meter: Follow the manufacturer’s instructions to calibrate the meter before use.
3. Measure moisture content: Insert the probes of the moisture meter into the wood and take readings at various depths.
4. Interpret results: Compare the readings with the ideal moisture content for your woodturning project.
Benefits of Moisture Mapping
* Ensures optimal woodturning results
* Prevents warping, cracking, and splitting
* Improves the quality and finish of the turned object
* Assists with wood selection for specific projects
