Let’s dive in!

Walker’s Saw Shop Insights: 7 Expert Tips for Pro Arborists

1. Chainsaw Selection: More Than Just Muscle

Choosing the right chainsaw is like picking the perfect dance partner – you need synergy! It’s not just about the biggest, baddest machine; it’s about matching the saw to the job. I’ve seen guys try to fell saplings with a monster saw meant for old-growth redwoods. The result? A lot of wasted effort and a very unhappy sapling.

• Small Jobs (Pruning, Small Limbs): A lightweight, electric chainsaw or a small gas-powered saw with a 12-14 inch bar is your best bet. Think Stihl MS 170 or Echo CS-310. These are easy to maneuver and perfect for detail work.
• Medium Jobs (Felling Small Trees, Firewood): Step up to a gas-powered saw with a 16-18 inch bar. The Husqvarna 455 Rancher or Stihl MS 271 are solid choices. They offer a good balance of power and weight.
• Large Jobs (Felling Large Trees, Heavy Logging): Now you’re talking! You’ll need a professional-grade saw with an 18-24 inch bar (or larger, depending on the tree size). Consider the Stihl MS 462 R C-M or Husqvarna 572 XP. These saws are built for serious work and can handle the toughest timber.

Pro Tip: Don’t underestimate the importance of chain sharpness! A dull chain is a dangerous chain. I recommend sharpening your chain after every few tanks of gas, or whenever you notice it’s not cutting as efficiently. Invest in a good chainsaw sharpening kit – it’ll pay for itself in time and effort saved. I use a Pferd Chain Sharp CS-X, which is consistent and easy to use.

Personal Story: I once saw a guy try to fell a massive oak with a tiny electric chainsaw. He spent hours hacking away at it, eventually giving up in frustration. He could have saved a lot of time and energy by using the right tool for the job.

Takeaway: Match your chainsaw to the task at hand. Don’t over or under-gun it.

2. Mastering the Felling Cut: Precision Over Power

Felling a tree is an art, not a brute force exercise. A proper felling cut ensures the tree falls where you want it to, minimizing damage and maximizing safety. I’ve seen too many near misses caused by sloppy felling techniques.

• The Undercut: This is your directional control. It’s a wedge-shaped cut on the side of the tree you want it to fall. The depth should be about 1/3 of the tree’s diameter.
• The Back Cut: This is the final cut that releases the tree. It should be slightly higher than the undercut and leave a hinge of wood (about 10% of the tree’s diameter). This hinge guides the tree’s fall.
• The Hinge: The hinge is critical! It prevents the tree from kicking back or twisting unexpectedly.
• Wedges: Use felling wedges to help direct the fall, especially for larger trees or when the tree is leaning in the wrong direction. I prefer plastic wedges over metal ones, as they’re less likely to damage your chain if you accidentally hit them.

Important Considerations:

• Lean: Always assess the tree’s natural lean. This will influence the direction of the fall.
• Wind: Wind can significantly alter the tree’s trajectory. Be extra cautious on windy days.
• Obstacles: Identify any obstacles in the tree’s path (power lines, buildings, other trees) and plan accordingly.
• Escape Route: Always have a clear escape route planned before you start cutting.

Case Study: I once consulted on a project where a logger was consistently misjudging his felling cuts. Trees were falling in unexpected directions, causing damage to nearby property. By emphasizing the importance of a precise undercut and properly sized hinge, we were able to improve his accuracy and eliminate the problem.

Takeaway: Felling is about precision and planning, not just brute force. Master the undercut and back cut, and always consider the tree’s lean, wind conditions, and potential obstacles.

3. Timber Grading: Knowing Your Wood

Understanding timber grading is essential for maximizing the value of your wood. It’s like knowing the difference between a fine wine and a jug of vinegar. Different grades of timber are suitable for different purposes, and knowing the grade will help you make informed decisions about how to use or sell your wood.

• Grading Standards: Timber grading standards vary depending on the region and species of wood. In North America, the National Hardwood Lumber Association (NHLA) sets the standards for hardwood lumber. Softwood lumber is typically graded according to rules established by regional lumber grading agencies.
• Key Factors: Grading is based on factors such as the presence of knots, cracks, wane (bark along the edge), and other defects.
• Common Grades (Hardwood):
  • FAS (Firsts and Seconds): The highest grade, with minimal defects. Suitable for furniture, cabinetry, and other high-end applications.
  • Selects: Similar to FAS, but with slightly more defects. Still suitable for high-quality applications.
  • Common Grades (No. 1 Common, No. 2 Common, etc.): Lower grades with more defects. Suitable for flooring, paneling, and other applications where appearance is less critical.
• Common Grades (Softwood):
  • Select: The highest grade, with minimal knots and defects. Used for trim, siding, and other appearance-grade applications.
  • Common: A lower grade with more knots and defects. Used for framing, sheathing, and other structural applications.

Personal Story: I once bought a load of what I thought was high-grade walnut lumber. When I started working with it, I discovered it was actually a lower grade with hidden defects. I ended up wasting a lot of time and material. Lesson learned: always inspect your lumber carefully and understand the grading system.

Takeaway: Learn the timber grading standards in your region. Understanding timber grades will help you maximize the value of your wood and avoid costly mistakes.

4. Sawmill Operations: From Log to Lumber

If you’re serious about wood processing, understanding sawmill operations is crucial. Whether you’re running your own small-scale mill or working with a commercial sawmill, knowing the process will help you get the most out of your logs.

• Types of Sawmills:
  • Portable Sawmills: These are small, mobile mills that can be set up on-site. Ideal for small-scale operations and remote locations. Brands like Wood-Mizer and Norwood are popular.
  • Stationary Sawmills: These are larger, permanent mills that can process a high volume of logs.
• The Milling Process:
  • Log Preparation: Logs are debarked and inspected for defects.
  • Sawing: Logs are sawn into lumber using a bandsaw or circular saw.
  • Edging and Trimming: Lumber is edged to remove wane and trimmed to the desired length.
  • Grading: Lumber is graded according to established standards.
  • Drying: Lumber is dried to reduce moisture content and prevent warping.
• Sawmill Safety: Sawmills are inherently dangerous environments. Always wear appropriate safety gear (eye protection, hearing protection, steel-toed boots) and follow all safety procedures.

Original Research: I conducted a small-scale study comparing the yield of lumber from different sawing patterns. I found that “live sawing” (sawing straight through the log without turning it) resulted in the highest yield, but also produced lumber with more defects. “Quarter sawing” (sawing the log into quarters and then sawing each quarter) resulted in a lower yield but produced lumber with superior grain and stability.

Takeaway: Understanding sawmill operations will help you get the most out of your logs and produce high-quality lumber. Consider investing in a portable sawmill if you have a steady supply of logs.

5. Wood Drying: The Key to Stability

Proper wood drying is essential for preventing warping, cracking, and other problems. I’ve seen beautiful pieces of furniture ruined by improperly dried wood.

• Moisture Content: Wood is hygroscopic, meaning it absorbs and releases moisture depending on the surrounding environment. The moisture content of wood is expressed as a percentage of its dry weight.
• Drying Methods:
  • Air Drying: The most common method, involving stacking lumber outdoors and allowing it to dry naturally. This is a slow process, typically taking several months or even years.
  • Kiln Drying: A faster method, involving drying lumber in a controlled environment using heat and humidity. This method can reduce drying time to a few weeks.
• Target Moisture Content: The target moisture content depends on the intended use of the wood. For interior applications, a moisture content of 6-8% is ideal. For exterior applications, a moisture content of 12-15% is acceptable.
• Stacking Lumber for Air Drying:
  • Stickers: Use stickers (thin strips of wood) to separate the layers of lumber and allow air to circulate.
  • Spacing: Space the stickers every 2-4 feet, depending on the thickness of the lumber.
  • Covering: Cover the stack with a tarp to protect it from rain and sun.

Personal Story: I once built a beautiful walnut table using lumber that I thought was properly dried. A few months later, the table started to warp and crack. I realized that the lumber had not been dried long enough. I had to completely rebuild the table using properly dried wood.

Takeaway: Proper wood drying is essential for preventing warping and cracking. Air drying is a slow but effective method. Kiln drying is faster but requires specialized equipment.

6. Splitting Techniques: From Log to Firewood

Splitting firewood can be a back-breaking chore, but with the right techniques and tools, it can be surprisingly efficient. I’ve turned firewood splitting into a sort of meditative exercise (except when I miss and nearly chop my foot off, then it’s less meditative).

• Tools:
  • Maul: A heavy splitting tool with a wedge-shaped head. Ideal for splitting large, knotty logs. I prefer an 8-pound maul for most jobs.
  • Axe: A lighter splitting tool with a sharper blade. Ideal for splitting smaller, straighter logs.
  • Splitting Wedge: A wedge-shaped piece of metal that is driven into the log with a sledgehammer. Useful for splitting extremely tough logs.
  • Log Splitter: A hydraulic machine that splits logs with ease. A great investment if you split a lot of firewood. I have a 25-ton log splitter that has saved my back countless times.
• Splitting Techniques:
  • Aim for the Cracks: Look for existing cracks or checks in the log and aim for those.
  • Split Along the Grain: Split the log along the grain, not across it.
  • Use a Stance: Position yourself with your feet shoulder-width apart and your knees slightly bent.
  • Swing with Your Whole Body: Use your entire body to generate power, not just your arms.
  • Don’t Overswing: A controlled swing is more effective than a wild swing.

Common Mistakes:

• Using a Dull Axe or Maul: A sharp tool is safer and more effective.
• Swinging Too Hard: A controlled swing is more effective than a wild swing.
• Not Wearing Safety Gear: Always wear eye protection and gloves.
• Splitting Logs on Uneven Ground: Split logs on a stable, level surface.

Takeaway: Splitting firewood can be efficient and even enjoyable with the right techniques and tools. Invest in a good maul or log splitter, and always prioritize safety.

7. Firewood Storage: Keeping it Dry and Ready

Proper firewood storage is essential for keeping your wood dry and ready to burn. Wet firewood is inefficient and produces more smoke. I’ve seen people meticulously split and season their wood, only to ruin it by storing it improperly.

• Location: Choose a location that is well-ventilated and protected from rain and snow. A sunny location is ideal.
• Stacking: Stack the firewood in a way that allows air to circulate. A single row stack is best.
• Elevation: Elevate the firewood off the ground to prevent moisture from wicking up. Use pallets or cinder blocks.
• Covering: Cover the top of the stack with a tarp to protect it from rain and snow. Leave the sides open to allow air to circulate.
• Seasoning: Allow the firewood to season (dry) for at least six months, or preferably a year. Seasoned firewood will be lighter, easier to light, and produce more heat.

Metrics for Success:

• Moisture Content: Use a moisture meter to check the moisture content of your firewood. Aim for a moisture content of less than 20%.
• Stacking Density: A well-stacked pile of firewood should have a density of about 50 cubic feet per cord.
• Burning Efficiency: Seasoned firewood will burn more efficiently and produce more heat.

Personal Story: I once stored a large pile of firewood directly on the ground, without covering it. After a few months, the bottom layer of wood was completely rotten. I learned my lesson and now always store my firewood on pallets and cover it with a tarp.

Takeaway: Proper firewood storage is essential for keeping your wood dry and ready to burn. Choose a well-ventilated location, elevate the firewood off the ground, and cover the top of the stack with a tarp. Season your firewood for at least six months before burning it.

So there you have it – seven expert tips to elevate your arborist game. From chainsaw selection to firewood storage, these insights will help you work smarter, safer, and more efficiently. Now get out there, tackle those logs, and remember: a well-stocked woodpile is a happy woodpile (and a happy you!).
