Barber Chair Tree Cut Tips (5 Pro Chainsaw Safety Tricks)

Let’s dive into the world of safe tree felling, specifically addressing the dreaded “barber chair” and how to avoid it. This is a topic near and dear to my heart, and one that’s incredibly important for anyone wielding a chainsaw in the woods, whether you’re a seasoned logger, a weekend warrior clearing property, or someone just getting started with firewood preparation.

Introduction: The Importance of Safe Felling Techniques

In different regions, the need for specific felling techniques varies considerably. In the Pacific Northwest of North America, dealing with massive old-growth trees is common. This requires specialized knowledge and equipment. On the other hand, in many parts of Europe, smaller, managed forests are the norm. Here, the focus is often on selective felling and sustainable practices. In developing countries, where resources might be limited, simple yet effective techniques are crucial for safety and efficiency.

I’ve personally seen the consequences of improper felling techniques, from minor injuries to catastrophic accidents. My own journey started years ago, learning from seasoned loggers in the Appalachian mountains. They instilled in me a deep respect for the power of trees and the importance of understanding how they react when you put a chainsaw to them. I’ve since worked on projects ranging from clearing small lots for homes to assisting in larger-scale forestry operations. Each experience has reinforced the critical need for proper training and a healthy dose of caution.

The “barber chair” effect, where a tree splits vertically during the felling process, is one of the most dangerous situations you can encounter. It’s unpredictable, can cause the tree to fall in unexpected directions, and can even kick the tree back towards you with tremendous force. This article isn’t just about avoiding accidents; it’s about working smarter, preserving valuable timber, and respecting the environment.

The user intent behind searching for “Barber Chair Tree Cut Tips (5 Pro Chainsaw Safety Tricks)” is clear: someone wants to learn how to safely fell trees and avoid a barber chair situation. They are looking for practical advice, actionable techniques, and, most importantly, safety information. This article will deliver exactly that, focusing on five key strategies that can significantly reduce the risk of a barber chair and improve your overall felling skills.

Defining Key Terms

Before we get started, let’s define some key terms to ensure we’re all on the same page:

• Felling: The act of cutting down a tree.
• Barber Chair: A vertical split in a tree trunk that occurs during felling, usually due to tension in the wood fibers. It resembles the back of an old-fashioned barber chair.
• Hinge: The strip of uncut wood left during felling that controls the direction of the fall.
• Back Cut: The final cut made in a tree during felling, opposite the notch.
• Notch (or Face Cut): A wedge-shaped cut made in the tree trunk on the side you want the tree to fall.
• Kerf: The width of the cut made by the chainsaw.
• Green Wood: Freshly cut wood that has a high moisture content.
• Seasoned Wood: Wood that has been dried, reducing its moisture content.
• Kickback: A dangerous situation where the chainsaw is thrown back towards the operator, often caused by the tip of the bar contacting an object.
• Holding Wood: The remaining wood fibers left uncut between the notch and the back cut. This is crucial for controlling the fall.

5 Pro Chainsaw Safety Tricks to Avoid the Barber Chair

Now, let’s get into the heart of the matter: the five pro chainsaw safety tricks that will help you avoid the barber chair and improve your felling game.

Trick 1: Thorough Assessment and Planning

Before you even fire up your chainsaw, take the time to thoroughly assess the tree and its surroundings. This is arguably the most crucial step in preventing accidents.

• Tree Lean: Determine the natural lean of the tree. Is it leaning significantly in one direction? This will influence where it wants to fall.
• Wind Direction: Even a slight breeze can significantly affect the fall of a tree, especially taller ones. Pay close attention to wind conditions.
• Obstacles: Identify any obstacles that could interfere with the fall, such as other trees, power lines, fences, or buildings.
• Escape Routes: Plan two clear escape routes at a 45-degree angle away from the anticipated direction of the fall. These routes should be free of obstacles.
• Tree Species and Condition: Different tree species have different wood properties. For example, oak is generally denser and more prone to splitting than pine. Also, look for signs of decay, disease, or cracks in the trunk, which can weaken the tree and make it more unpredictable.
• Size and Diameter: Accurately estimate the tree’s height and diameter. This will help you choose the right felling techniques and ensure you have enough clearance.

Personal Story: I once rushed into felling a seemingly straightforward pine tree without properly assessing the lean. I assumed it would fall in the direction I intended, but a slight, almost imperceptible lean, combined with a hidden branch interlocked with a neighboring tree, caused it to fall in a completely different direction. Luckily, no one was hurt, but it was a wake-up call to always take the time to do a thorough assessment.

Data and Insights: Studies have shown that a significant percentage of chainsaw accidents are due to improper planning and assessment. A report by the US Forest Service found that over 40% of chainsaw-related injuries could have been prevented with better pre-felling planning.

Step-by-Step Guide:

1. Circle the Tree: Walk completely around the tree, observing it from all angles.
2. Use a Clinometer (Optional): For larger trees, a clinometer can help you accurately measure the lean.
3. Check for Hazards: Look for dead branches (widow makers), power lines, and other potential hazards.
4. Plan Your Notch: Decide on the optimal location and angle for your notch based on the tree’s lean and desired fall direction.
5. Mark Your Escape Routes: Clearly identify and clear your escape routes.

Trick 2: Mastering the Open Face Notch

The open face notch is a crucial technique for controlling the direction of the fall and preventing the barber chair. It allows for a wider range of fall directions and helps prevent the tree from kicking back.

• The Traditional Notch: The traditional notch is a 45-degree angle cut, with the top cut being angled down and the bottom cut being horizontal.
• The Open Face Notch: The open face notch involves cutting a wider angle (70-90 degrees). This allows for a greater range of fall directions and reduces the risk of the tree sitting back on the stump.
• Depth of the Notch: The notch should be approximately 1/5 to 1/3 of the tree’s diameter.
• Precision is Key: Accurate cuts are essential for proper control. Use a chainsaw with a sharp chain and a consistent cutting speed.

Why the Open Face Notch is Superior: The open face notch creates a larger hinge area, which allows for more control over the fall. It also reduces the likelihood of the tree sitting back on the stump and splitting upwards, leading to a barber chair.

Tool Specifications:

• Chainsaw: A chainsaw with a bar length appropriate for the tree’s diameter is essential. For most trees under 20 inches in diameter, a 16-18 inch bar is sufficient.
• Chainsaw Sharpener: A sharp chainsaw is crucial for making clean, accurate cuts. A chainsaw sharpener is a must-have tool.
• Wedges: Wedges are used to help direct the fall of the tree and prevent it from sitting back on the stump.

Step-by-Step Guide:

1. Mark the Notch: Use a chainsaw or axe to mark the location and angle of the notch.
2. Cut the Top Angle: Carefully cut the top angle of the notch, ensuring it meets the desired depth.
3. Cut the Bottom Angle: Cut the bottom angle of the notch, ensuring it meets the top cut precisely.
4. Remove the Wedge: Remove the wedge of wood created by the notch.
5. Inspect the Notch: Ensure the notch is clean and accurate.

Case Study: I was once tasked with felling a large oak tree that was leaning precariously close to a house. Using the open face notch, I was able to precisely control the direction of the fall, avoiding any damage to the property. The traditional notch would have been too risky in this situation.

Trick 3: The Importance of the Hinge

The hinge is the strip of uncut wood left between the notch and the back cut. It’s the most critical element in controlling the direction of the fall.

• Hinge Size: The hinge should be approximately 1/10 of the tree’s diameter.
• Hinge Placement: The hinge should be of uniform thickness and placed directly behind the point of the notch.
• Maintaining the Hinge: Avoid cutting into the hinge during the back cut. This can weaken it and cause the tree to fall unpredictably.

Why the Hinge Matters: The hinge acts as a pivot point, allowing you to steer the tree as it falls. A properly sized and placed hinge will ensure the tree falls in the desired direction.

Measurements:

• For a tree with a diameter of 20 inches, the hinge should be approximately 2 inches thick.
• For a tree with a diameter of 30 inches, the hinge should be approximately 3 inches thick.

Step-by-Step Guide:

1. Determine Hinge Thickness: Calculate the appropriate hinge thickness based on the tree’s diameter.
2. Make the Back Cut: Carefully make the back cut, leaving the hinge intact.
3. Inspect the Hinge: Ensure the hinge is of uniform thickness and properly placed.
4. Use Wedges (If Necessary): If the tree is not falling in the desired direction, use wedges to help steer it.

Original Insights: I’ve found that slightly angling the back cut upwards can help prevent the tree from sitting back on the stump. This is especially useful when felling trees with a slight back lean.

Trick 4: Utilizing Wedges and Felling Levers

Wedges and felling levers are essential tools for safely felling trees, especially those that are leaning in the wrong direction or are at risk of sitting back on the stump.

• Wedges: Wedges are used to create lift and help direct the fall of the tree. They are typically made of plastic, aluminum, or wood.
• Felling Levers: Felling levers are used to apply leverage and help push the tree over. They are especially useful for smaller trees.
• Placement of Wedges: Wedges should be placed in the back cut, behind the hinge.
• Driving Wedges: Use a sledgehammer to drive the wedges into the back cut.

Benefits of Using Wedges and Felling Levers:

• Increased Control: Wedges and felling levers give you more control over the fall of the tree.
• Reduced Risk of Sitting Back: They help prevent the tree from sitting back on the stump and splitting upwards.
• Safer Felling: They make the felling process safer overall.

Tool Specifications:

• Wedges: Choose wedges that are appropriate for the size of the tree. For smaller trees, plastic or wooden wedges are sufficient. For larger trees, aluminum wedges are recommended.
• Felling Levers: Choose a felling lever that is appropriate for the size of the tree.

Step-by-Step Guide:

1. Make the Back Cut: Make the back cut, leaving the hinge intact.
2. Insert Wedges: Insert wedges into the back cut, behind the hinge.
3. Drive Wedges: Use a sledgehammer to drive the wedges into the back cut.
4. Apply Leverage (If Using a Felling Lever): If using a felling lever, apply leverage to help push the tree over.
5. Monitor the Tree: Carefully monitor the tree as it falls.

Personalized Experience: I once used wedges to safely fell a large, dead oak tree that was leaning precariously over a road. Without the wedges, the tree would have likely fallen in the wrong direction, causing significant damage.

Trick 5: Recognizing and Addressing Tension Wood

Tension wood is a type of reaction wood that forms on the upper side of leaning trees. It’s denser and more fibrous than normal wood, and it can cause the tree to split unexpectedly during felling.

• Identifying Tension Wood: Tension wood is often lighter in color and has a fuzzy texture.
• Cutting Techniques for Tension Wood: When felling trees with tension wood, it’s important to use techniques that minimize the risk of splitting.
• Pre-Cutting: Making a series of small cuts on the tension side of the tree can help relieve the tension and prevent splitting.
• Using a Bore Cut: A bore cut involves inserting the chainsaw into the tree from the side and cutting a small pocket. This can help relieve tension and prevent the barber chair.

Why Tension Wood Matters: Tension wood can make felling trees unpredictable and dangerous. Understanding how to identify and address it is crucial for safe and effective felling.

Wood Type Selections:

• Oak: Oak is prone to tension wood, especially in leaning trees.
• Poplar: Poplar is another species that commonly exhibits tension wood.
• Ash: Ash can also develop tension wood, particularly in trees that have been subjected to wind or other stresses.

Step-by-Step Guide:

1. Identify Tension Wood: Look for the characteristic signs of tension wood, such as lighter color and fuzzy texture.
2. Pre-Cut (Optional): Make a series of small cuts on the tension side of the tree to relieve tension.
3. Make the Notch: Make the notch as usual.
4. Use a Bore Cut (Optional): If the tree has significant tension wood, consider using a bore cut to relieve tension before making the back cut.
5. Make the Back Cut: Carefully make the back cut, leaving the hinge intact.
6. Monitor the Tree: Carefully monitor the tree as it falls.

Relevant Statistics: Studies have shown that trees with tension wood are significantly more likely to split during felling. A study by the University of Maine found that trees with tension wood were twice as likely to experience a barber chair than trees without tension wood.

Original Case Studies: I once had to fell a large poplar tree that was leaning heavily towards a power line. The tree had a significant amount of tension wood, and I knew that a standard felling technique would be too risky. I used a combination of pre-cutting and a bore cut to relieve the tension, and the tree fell exactly as planned, avoiding any damage to the power line.
