2. Planning the Felling Cut:
   • Escape Route: Plan a clear escape route at a 45-degree angle from the intended felling direction.
   • Notch Cut: The notch cut determines the direction of the fall. It should be approximately one-third of the tree’s diameter.
   • Hinge: The hinge is the uncut wood between the notch cut and the back cut. It controls the fall of the tree.
   • Back Cut: The back cut should be slightly above the notch cut and leave enough wood for the hinge.
3. Felling Procedure:
   • Clear the Area: Clear the area around the tree of any debris.
   • Notch Cut: Make the notch cut carefully, ensuring it is properly aligned.
   • Back Cut: Make the back cut slowly and deliberately, monitoring the tree’s movement.
   • Wedges: Use wedges to help control the fall of the tree and prevent the bar from getting pinched.
   • Warning Call: Before the tree falls, shout a warning call to alert anyone in the area.
   • Escape: Retreat along your planned escape route as the tree falls.
4. De-limbing:
   • Safe Stance: Maintain a stable stance and keep your body out of the path of the chain.
   • Cut from the Top: Cut branches from the top of the tree first.
   • Support Branches: Support branches before cutting them to prevent them from pinching the bar.
   • Avoid Kickback: Be aware of the kickback zone and avoid using it.

Data Point: Improper felling techniques are a leading cause of chainsaw-related injuries and fatalities.

Actionable Tip: Invest in a good quality sawhorse to make bucking easier and safer. Use a measuring stick to ensure consistent firewood lengths.

Pro Tip #5: Understanding Wood Seasoning and Storage for Optimal Burning

Seasoning firewood is the process of drying it to reduce its moisture content. Properly seasoned firewood burns more efficiently, produces less smoke, and reduces the risk of creosote buildup in your chimney.

1. Green Wood vs. Seasoned Wood:
   • Green Wood: Wood that has been recently cut and contains a high moisture content (typically 50% or more).
   • Seasoned Wood: Wood that has been dried to a moisture content of 20% or less.
2. Benefits of Seasoned Wood:
   • Easier to Ignite: Seasoned wood ignites more easily and burns more consistently.
   • Higher Heat Output: Seasoned wood produces more heat per pound than green wood.
   • Less Smoke: Seasoned wood produces less smoke, reducing air pollution and creosote buildup.
   • Reduced Creosote Buildup: Creosote is a flammable substance that can accumulate in chimneys and cause chimney fires. Seasoned wood reduces creosote buildup.
3. Seasoning Process:
   • Splitting: Splitting the wood increases the surface area exposed to air, speeding up the drying process.
   • Stacking: Stack the firewood in a single row, off the ground, and with good air circulation.
   • Sun and Wind Exposure: Expose the firewood to direct sunlight and wind to promote drying.
   • Covering: Cover the top of the stack to protect it from rain and snow.
   • Drying Time: Allow the firewood to season for at least six months, or preferably a year or more.
4. Moisture Content Measurement:
   • Moisture Meter: Use a moisture meter to measure the moisture content of the firewood.
   • Visual Inspection: Seasoned wood is typically lighter in color and weight than green wood.
   • Sound Test: Seasoned wood produces a hollow sound when struck, while green wood produces a dull thud.

Data Point: Burning seasoned firewood can increase heating efficiency by up to 25% and reduce creosote buildup by 50%.

Case Study: A local homeowner switched from burning green wood to seasoned wood and reported a significant reduction in chimney cleaning costs and improved heating efficiency.
