Locust Thorn Tree Care (Chainsaw Tips for Safe Wood Processing)

Introduction: Respecting the Land, Harnessing the Locust

Understanding the Black Locust: A Woodworker’s Perspective

Before we even think about firing up a chainsaw, it’s crucial to understand the Black Locust (Robinia pseudoacacia). This isn’t just any tree; it’s a powerhouse of potential, but also a challenge to work with.

Wood Anatomy and Properties: The Secrets Within

The Black Locust’s exceptional qualities stem from its unique wood anatomy. It’s a hardwood, meaning it has a complex cellular structure that contributes to its density and strength. But let’s dive deeper:

• Density: Black Locust boasts an impressive density, typically ranging from 44 to 54 pounds per cubic foot when dry. This density is a key indicator of its strength and durability.
• Durability: Due to the presence of naturally occurring extractives (chemicals) that act as preservatives, Black Locust is highly resistant to decay and insect infestation. I’ve personally seen Locust posts remain solid in the ground for decades, outlasting many treated softwoods.
• Grain: The grain is generally straight, but can be interlocked, making it moderately difficult to split by hand. This is where understanding wood grain direction and using appropriate splitting techniques becomes essential.
• Hardness: On the Janka hardness scale, Black Locust scores around 1,700 lbf, significantly higher than many other hardwoods commonly used for firewood. This hardness translates to a longer burn time and higher heat output.
• Moisture Content: Freshly cut Black Locust can have a moisture content of over 80%. Properly seasoning it down to 20% or less is critical for efficient burning.
• Thorns: Its formidable thorns are a defining characteristic. These can be quite dangerous if not handled with care, making protective gear a must.

Why Black Locust is Worth the Effort: Benefits Beyond the Thorns

Despite the challenges, Black Locust offers significant advantages:

• High BTU Rating: Black Locust has one of the highest BTU (British Thermal Unit) ratings of any firewood species commonly found in North America, typically around 27.8 million BTU per cord. This means it produces a lot of heat for its volume.
• Long Burning Time: Due to its density, Black Locust burns slowly and steadily, providing consistent heat for extended periods.
• Low Smoke Production: When properly seasoned, Black Locust burns relatively cleanly, producing less smoke than many other firewood species.
• Sustainable Choice: Black Locust is a fast-growing tree that can thrive in poor soil conditions. It’s also nitrogen-fixing, meaning it enriches the soil. Harvesting it responsibly can contribute to sustainable forestry practices.

Personal Story: I remember one particularly cold winter where our primary firewood source was running low. A neighbor offered us a fallen Black Locust tree. Initially, I was hesitant due to its reputation for being difficult to process. However, after properly seasoning the wood, we were amazed by its heat output. It kept our home significantly warmer, and we used far less wood overall. That experience solidified my appreciation for Black Locust’s potential.

Logging Tool Selection: Equipping Yourself for Success

Choosing the right tools is paramount for safe and efficient Black Locust processing. This isn’t just about having the best equipment; it’s about having the right equipment for the job.

Chainsaws: Power and Precision

• Size Matters: For felling larger Black Locust trees, a chainsaw with a bar length of 18-20 inches and an engine displacement of 50-60cc is generally sufficient. For smaller trees and limbing, a smaller saw with a 14-16 inch bar and 40-45cc engine will be more maneuverable.
• Chain Type: A full-chisel chain is more aggressive and cuts faster, but it requires more sharpening. A semi-chisel chain is more forgiving and stays sharp longer, making it a good choice for beginners. I personally prefer a full-chisel chain for its speed, but I’m meticulous about sharpening.
• Safety Features: Always ensure your chainsaw has a functioning chain brake, throttle lock, and chain catcher. These safety features can prevent serious injuries.
• Maintenance: Regular maintenance is crucial. This includes sharpening the chain, cleaning the air filter, checking the spark plug, and lubricating the bar and chain. A dull chain is not only inefficient but also dangerous.

Splitting Tools: Manual vs. Hydraulic

• Manual Splitting: For smaller rounds and those who enjoy the physical challenge, a maul or splitting axe is a viable option. Look for a maul with a heavy head (6-8 pounds) and a splitting axe with a wedge-shaped head. I still use a maul for smaller rounds; it’s a great workout!
• Hydraulic Splitters: For larger rounds and those who want to save time and effort, a hydraulic splitter is a game-changer. Look for a splitter with a tonnage rating of at least 20 tons. Consider models with a horizontal and vertical splitting option for added versatility.
• Wedges: Steel splitting wedges can be used in conjunction with a sledgehammer to split particularly stubborn rounds. I always keep a few wedges on hand; they’ve saved me countless headaches.

Personal Protective Equipment (PPE): Your First Line of Defense

• Helmet: A helmet with a face shield and ear protection is essential. This protects your head, face, and hearing from flying debris and chainsaw noise.
• Eye Protection: Safety glasses or goggles should be worn even when using a face shield.
• Hearing Protection: Earplugs or earmuffs are crucial to prevent hearing damage from prolonged chainsaw use.
• Gloves: Heavy-duty work gloves protect your hands from cuts, scrapes, and thorns.
• Chainsaw Chaps: Chainsaw chaps are designed to stop a chainsaw chain in the event of contact with your legs. They are a non-negotiable safety item.
• Steel-Toed Boots: Steel-toed boots protect your feet from falling logs and chainsaw accidents.

Data Point: According to the U.S. Consumer Product Safety Commission, chainsaw-related injuries result in over 30,000 emergency room visits each year. Wearing appropriate PPE can significantly reduce your risk of injury.

Chainsaw Techniques for Black Locust: Mastering the Cut

Cutting Black Locust safely and efficiently requires mastering specific chainsaw techniques. This isn’t just about knowing how to start a saw; it’s about understanding how to control it and anticipate the wood’s behavior.

Felling Techniques: Bringing the Tree Down Safely

• Assess the Tree: Before making any cuts, assess the tree for lean, wind direction, and any hazards such as dead branches or power lines.
• Plan Your Escape Route: Identify a clear escape route that is 45 degrees away from the direction of the fall.
• Notch Cut: The notch cut determines the direction of the fall. It should be made at a 70-degree angle, with the bottom cut being slightly deeper than the top cut.
• Back Cut: The back cut should be made slightly above the notch cut, leaving a hinge of wood to control the fall of the tree.
• Wedges: If the tree is leaning in the wrong direction, use felling wedges to help guide its fall.

Limbing and Bucking: Processing the Tree into Manageable Pieces

• Limbing: Start by limbing the tree from the base to the top, working on the uphill side. Use a chainsaw or a hatchet to remove the branches. Be mindful of spring poles (branches under tension) that can snap back when cut.
• Bucking: Bucking is the process of cutting the tree into shorter, more manageable lengths. Use a measuring tape to ensure consistent lengths.
• Cutting Techniques: Use appropriate cutting techniques to avoid pinching the saw. These include:
  • Overbuck: Cutting from the top down when the log is supported at both ends.
  • Underbuck: Cutting from the bottom up when the log is supported in the middle.
  • Bore Cut: A technique used to relieve tension in the log before making the final cut.

Tip: When bucking Black Locust, be prepared for internal stresses in the wood. Make small, incremental cuts to avoid the wood pinching the saw or splitting unexpectedly.

Dealing with Thorns: A Prickly Situation

• Protective Clothing: Wear thick gloves and long sleeves to protect yourself from thorns.
• Pruning Shears: Use pruning shears to remove small thorns before handling the wood.
• Chainsaw: Carefully use the chainsaw to remove larger thorns. Be extra cautious to avoid kickback.
• Disposal: Dispose of thorny branches properly to prevent injuries. Consider burning them or burying them in a designated area.

Personal Story: I once underestimated the reach of a Black Locust thorn and ended up with a puncture wound that became infected. It was a painful reminder of the importance of wearing proper protective gear and handling the wood with respect.

Firewood Seasoning: Unlocking the Heat Potential

Seasoning firewood is the process of drying it to reduce its moisture content. Properly seasoned firewood burns hotter, cleaner, and more efficiently. With Black Locust, seasoning is particularly crucial due to its initial high moisture content.

The Science of Seasoning: Moisture Content Dynamics

• Freshly Cut Wood: As mentioned earlier, freshly cut Black Locust can have a moisture content of over 80%.
• Target Moisture Content: The ideal moisture content for firewood is 20% or less. At this level, the wood burns efficiently and produces minimal smoke.
• Drying Process: As wood dries, water evaporates from the cells. This process is influenced by temperature, humidity, and airflow.
• Moisture Meters: A moisture meter is a valuable tool for measuring the moisture content of firewood. I highly recommend investing in one.

Seasoning Techniques: Maximizing Airflow and Sunlight

• Stacking: Stack the firewood in loose rows, allowing for maximum airflow. Elevate the wood off the ground using pallets or scrap wood.
• Sunlight: Expose the wood to direct sunlight as much as possible. Sunlight helps to accelerate the drying process.
• Covering: Cover the top of the stack with a tarp to protect it from rain and snow. Leave the sides open to allow for airflow.
• Airflow: Ensure good airflow around the stack. Avoid stacking wood in enclosed areas or against walls.

Timeframe: Patience is Key

• General Rule: As a general rule, firewood should be seasoned for at least six months, and preferably a year.
• Black Locust: Due to its density, Black Locust may require longer seasoning times. I recommend seasoning it for at least 12-18 months.
• Climate: The seasoning time will also depend on your climate. In dry climates, wood will dry faster than in humid climates.

Data Point: Studies have shown that properly seasoned firewood can produce up to 50% more heat than green wood.

Firewood Storage: Keeping it Dry

• Location: Store seasoned firewood in a dry, well-ventilated area.
• Elevated: Keep the wood elevated off the ground to prevent moisture from wicking up.
• Covered: Cover the wood to protect it from rain and snow.
• Pest Control: Inspect the wood regularly for signs of pests.

Personal Story: I once made the mistake of burning unseasoned Black Locust in my wood stove. The fire was difficult to start, produced a lot of smoke, and left a sticky residue in the chimney. It was a lesson learned the hard way about the importance of proper seasoning.

Break-Even Analysis: Calculating the Value

To determine if processing Black Locust is worth the investment, calculate the cost per cord of firewood and compare it to the market price. Consider the value of your time and the potential for selling excess firewood.

Example:

• Equipment Costs: \$500
• Fuel and Maintenance: \$100 per cord
• Time (estimated): 10 hours per cord
• Market Price of Firewood: \$250 per cord

If you value your time at \$15 per hour, the total cost per cord would be \$150 (fuel and maintenance) + \$150 (labor) + (\$500 / number of cords processed). If you process 5 cords, the equipment cost adds \$100 per cord, bringing the total cost to \$400. In this scenario, processing Black Locust would not be economically viable unless you can significantly reduce your costs or increase the market price of the firewood. However, if you value the wood for personal use and prioritize the benefits of high heat output and long burning time, it may still be worthwhile.
