Chestnuts Old Saws: Best Firewood Cuts (5 Pro Arborist Tips)

1. Understanding Wood Species: Not All Wood is Created Equal

The foundation of any good firewood preparation strategy lies in understanding the wood you’re working with. I’ve seen folks struggle endlessly with the wrong wood, making the job ten times harder than it needs to be.

Different wood species have vastly different properties that affect how they burn, how easily they split, and how much heat they produce. This isn’t just about “hardwood versus softwood,” it’s about the specifics of each species.

• Hardwoods vs. Softwoods: Generally, hardwoods are denser and burn longer, producing more heat. Think oak, maple, ash, and yes, chestnut. Softwoods like pine, fir, and spruce ignite easily but burn faster and produce less heat. They’re great for kindling but not ideal as your primary firewood.
• Chestnut: The King is Back (Sort Of): American Chestnut was once a dominant species in eastern North America, prized for its rot resistance and straight grain. While blight decimated the original trees, hybrids are now becoming more common. Chestnut is a fantastic firewood, splitting relatively easily when green and burning with good heat output. Its low spark production makes it safer for open fireplaces.
• Data Point: Air-dried chestnut (15-20% moisture content) has a BTU (British Thermal Unit) rating of roughly 20 million BTUs per cord. That’s comparable to cherry or soft maple, making it a solid choice.
• My Experience: I once spent a winter relying solely on seasoned black locust and chestnut. The locust was a bear to split, but it burned forever. The chestnut was easier to handle and provided a consistent, reliable heat source. The combination was unbeatable.
• Actionable Takeaway: Before you even start your chainsaw, identify your wood species. Research its properties – BTU rating, ease of splitting, drying time – and adjust your processing strategy accordingly.

2. The Art of Bucking: Mastering the Cut for Easier Splitting

Bucking, or cutting the felled tree into manageable lengths, is where efficiency and safety truly begin. I’ve seen so many folks just hacking away at logs, creating dangerous situations and wasting energy. A well-planned bucking strategy can save you time, reduce strain, and make splitting much easier.

• Length Matters: Firewood length depends on your stove or fireplace size. Most folks aim for 16-18 inches. I personally prefer 16 inches because it fits in my stove perfectly and is easier to handle.
• Cutting Technique: Always cut on the compression side of the log. This prevents the saw from pinching and binding. If the log is supported at both ends, cut from the top down. If it’s supported in the middle, cut from the bottom up.
• Dealing with Tension: Logs under tension can be dangerous. If you suspect tension, make a shallow cut on the compression side first. This allows the wood to release tension gradually, preventing the saw from kicking back.
• The “Hinge” Cut: For larger logs, consider using a “hinge” cut. Cut most of the way through the log, leaving a small section (the “hinge”) intact. Then, roll the log over and finish the cut. This prevents the log from pinching the saw.
• Data Point: Studies show that proper bucking techniques can reduce chainsaw kickback injuries by up to 50%.
• My Experience: I once ignored the signs of tension in a large oak log. The saw pinched, kicked back violently, and nearly sent me flying. Lesson learned: always respect the wood and understand its stresses.
• Actionable Takeaway: Plan your cuts carefully. Consider the log’s support points, tension, and your desired firewood length. Use proper cutting techniques to prevent pinching and kickback.

3. Splitting Strategies: From Manual to Mechanical

Splitting firewood is often the most physically demanding part of the process. But with the right technique and tools, it can be surprisingly efficient. I’ve tried everything from axes to hydraulic splitters, and each has its place.

• Manual Splitting:
  • The Axe: A classic for a reason. Choose an axe with a sharp, heavy head (6-8 pounds). Aim for the center of the log, using a smooth, controlled swing.
  • The Splitting Maul: Designed for splitting, not felling. A maul has a heavier head (8-12 pounds) and a wider, more wedge-shaped blade. It’s ideal for tougher wood.
  • Wedges and Sledgehammers: For extremely stubborn logs, drive wedges into the wood using a sledgehammer.
• Mechanical Splitting:
  • Hydraulic Log Splitters: These come in various sizes, from small electric models to large gas-powered machines. They can split even the toughest wood with ease.
  • Kinetic Log Splitters: These use a flywheel to generate splitting force. They’re faster than hydraulic splitters but can be less powerful.
• Splitting Technique:
  • Aim for Weak Points: Look for cracks, knots, or other imperfections in the wood. These are natural splitting points.
  • Use a Solid Base: Split wood on a sturdy chopping block. A tire filled with dirt or sand works well.
  • Safety First: Wear safety glasses, gloves, and steel-toed boots. Keep your feet clear of the splitting area.
• Data Point: A hydraulic log splitter can split up to 5 cords of wood per day, compared to 1-2 cords for manual splitting.
• My Experience: I remember the first time I used a hydraulic log splitter. It was like going from a horse-drawn plow to a tractor. The sheer power and efficiency were incredible.
• Actionable Takeaway: Choose the right splitting method for your needs and budget. Learn proper splitting techniques to maximize efficiency and minimize strain. Always prioritize safety.

4. Seasoning Firewood: The Key to Efficient Burning

Seasoning, or drying, firewood is crucial for efficient burning. Green wood contains a high moisture content, which reduces its heat output and creates excessive smoke. I’ve seen folks try to burn unseasoned wood, and it’s a frustrating, smoky mess.

• The Science of Seasoning: As wood dries, its moisture content decreases, allowing it to burn hotter and cleaner. Ideally, firewood should be seasoned for at least six months, and preferably a year.
• Stacking for Success: Stack firewood in a single row, off the ground, in a sunny, windy location. This allows air to circulate freely around the wood, promoting drying.
• Covering the Top: Cover the top of the woodpile with a tarp or roof to protect it from rain and snow. However, leave the sides open for ventilation.
• Moisture Meters: Use a moisture meter to check the moisture content of your firewood. Ideally, it should be below 20%.
• Wood Species and Drying Time: Different wood species dry at different rates. Softwoods dry faster than hardwoods. Chestnut, being moderately dense, will take a good 6-12 months to season properly.
• Data Point: Seasoned firewood produces up to 50% more heat than green wood and reduces creosote buildup in your chimney.
• My Experience: I once tried to burn some “partially seasoned” oak. It was a disaster. The fire smoldered, produced tons of smoke, and barely heated the house. Stack it in a sunny, windy location, off the ground, and cover the top. Use a moisture meter to check its moisture content.

5. Chainsaw Maintenance and Safety: Respect the Beast

A chainsaw is a powerful tool, but it can also be dangerous if not used properly. I’ve seen too many accidents caused by carelessness or lack of maintenance. Regular maintenance and strict adherence to safety protocols are essential.

• Chainsaw Maintenance:
  • Sharpening the Chain: A sharp chain is crucial for efficient cutting and safety. Sharpen the chain regularly using a file or a chainsaw sharpener.
  • Cleaning the Saw: Clean the saw after each use. Remove sawdust and debris from the bar, chain, and engine.
  • Checking the Bar: Inspect the bar for wear and damage. Replace it if necessary.
  • Maintaining the Engine: Follow the manufacturer’s instructions for engine maintenance, including oil changes and spark plug replacement.
• Chainsaw Safety:
  • Personal Protective Equipment (PPE): Always wear a helmet, safety glasses, hearing protection, gloves, chainsaw chaps, and steel-toed boots.
  • Proper Stance: Stand with your feet shoulder-width apart, with a firm grip on the saw.
  • Kickback Awareness: Be aware of the risk of kickback and take steps to prevent it.
  • Safe Cutting Techniques: Use proper cutting techniques to avoid pinching and binding.
  • Clear Work Area: Keep the work area clear of obstacles and bystanders.
• Data Point: Chainsaw-related injuries account for approximately 30,000 emergency room visits each year in the United States.
• My Experience: I once neglected to sharpen my chainsaw chain. The saw was dull and difficult to control. I was forcing it through the wood, which created a dangerous situation. I quickly stopped and sharpened the chain, realizing how much safer and more efficient a sharp saw is.
• Actionable Takeaway: Maintain your chainsaw regularly and follow all safety protocols. Wear appropriate PPE, use proper cutting techniques, and be aware of the risk of kickback.

Bonus Tip: The Old Saw Wisdom

Beyond the technical aspects, there’s a certain wisdom that comes from spending time in the woods. I’ve learned to listen to the trees, to respect the power of nature, and to appreciate the simple act of preparing firewood.

• “Measure twice, cut once.” This old carpenter’s adage applies perfectly to firewood preparation. Careful planning and precise cuts save time and effort in the long run.
• “A dull axe is a dangerous axe.” A dull axe requires more force to use, increasing the risk of injury. Keep your tools sharp and well-maintained.
• “Many hands make light work.” Don’t be afraid to ask for help. Firewood preparation is often a team effort.
• “Wood warms you twice: once when you cut it, and again when you burn it.” This saying captures the satisfaction of hard work and the comfort of a warm fire.

Case Study: From Blight to BTU – The Chestnut Comeback Project

I recently worked on a small-scale firewood harvesting project involving blight-resistant American Chestnut hybrids. The landowner had planted a grove of these trees several years ago, and they were now ready for thinning.

• Equipment Used: Stihl MS 261 chainsaw, Fiskars X27 splitting axe, hydraulic log splitter, moisture meter.
• Wood Type: Blight-resistant American Chestnut hybrid.
• Safety Considerations: Chainsaw chaps, helmet, safety glasses, hearing protection, gloves, steel-toed boots. Careful bucking techniques to avoid pinching.
• Processing Method: Trees were felled and bucked into 16-inch lengths. The logs were split using a combination of manual and mechanical methods. The firewood was stacked in a sunny, windy location for seasoning.
• Results: The chestnut firewood seasoned well over the summer and burned cleanly and efficiently in the winter. The landowner was pleased with the heat output and the low spark production.
• Key Takeaways: This project demonstrated the potential of blight-resistant chestnut as a sustainable firewood source. It also highlighted the importance of proper processing and seasoning techniques.
