The Importance of Understanding Wood

Before you even start sawing, it’s crucial to understand the wood you’re working with. This knowledge directly impacts your milling process and the quality of your final product.

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood that has a high moisture content, typically above 30%. Seasoned wood, on the other hand, has been dried to a moisture content of 12-18% for air-dried and 6-8% for kiln-dried. Green wood is easier to cut but is prone to warping and shrinking as it dries. Seasoned wood is more stable but can be harder to cut.
• Wood Species: Different wood species have different properties, such as density, hardness, and grain pattern. Understanding these properties is essential for choosing the right saw blade and cutting parameters. For example, hardwoods like oak and maple require a sharper blade and a slower feed rate than softwoods like pine and fir.
• Grain Orientation: The grain orientation of the wood can affect the stability and strength of the final product. It’s important to consider the grain orientation when milling lumber for specific applications, such as furniture or flooring.
• Moisture Content Measurement: I use a moisture meter religiously. It’s a small investment that saves big headaches. These meters measure the percentage of moisture in the wood, allowing you to determine whether it’s green or seasoned.

Practical Tips and Tricks from the Field

Over the years, I’ve picked up a few tricks that can help you get the most out of your Woodmizer LT40.
