Understanding Key Concepts

Before we jump into the tests, let’s define some key terms to ensure we’re all on the same page:

• Green Wood: Freshly cut wood with a high moisture content (often above 30%). It’s heavier and more difficult to split than seasoned wood.
• Seasoned Wood: Wood that has been allowed to dry for a period of time, reducing its moisture content (ideally below 20%). Seasoned wood is lighter, easier to split, and burns more efficiently.
• Bore Cutting: A technique where the saw is plunged directly into the wood, often used for felling trees or creating notches.
• Bucking: Cutting a felled tree into smaller, more manageable lengths.
• Limbing: Removing branches from a felled tree.
• Bar Oil: Special oil designed to lubricate the chain and bar of a chainsaw, reducing friction and wear.
• Chain Pitch: The distance between three consecutive rivets on the chain, divided by two.
• Chain Gauge: The thickness of the drive links that fit into the bar groove.
