Wouldn’t it be great if we could all fell trees with the confidence of a seasoned logger, avoiding those heart-stopping moments when things go sideways? Today, I’m diving deep into a topic that sends shivers down the spines of even experienced woodsmen: the dreaded barber chair. I’m going to share five expert logging tips to help you avoid this dangerous situation and ensure a safer, more productive tree felling experience. I have spent years in the woods, learning from the best (and sometimes, the hardest) of ways. Barber chairs are no joke, and understanding how to prevent them is crucial for anyone wielding a chainsaw.

Tree Felling Barber Chair Hazards (5 Expert Logging Tips)

Understanding the Barber Chair Phenomenon

The barber chair, in logging terms, refers to a dangerous and unpredictable split that occurs in a tree trunk during the felling process. Instead of a clean, controlled fall, the tree’s fibers splinter upwards from the hinge point, creating a hazardous “chair” shape. This can cause the tree to kick back violently, potentially injuring or even killing the logger. I have seen this happen firsthand, and it’s not a sight you ever want to witness.

Why does it happen? Barber chairs typically occur when the tree’s internal stresses are not properly managed during the cut. Factors contributing to this include:

• Tension Wood: Wood that is under tension, often found on the upper side of leaning trees.
• Improper Cutting Techniques: Not using the correct felling cuts can exacerbate internal stresses.
• Tree Defects: Internal rot, cracks, or other weaknesses can create unpredictable splitting.
• Dull Chains: A dull chain increases the risk of tearing the wood fibers instead of cutting cleanly.
• Tree Size and Species: Some species, like certain hardwoods, are more prone to barber chairs.

The Danger: The sudden release of energy when a barber chair occurs can be incredibly violent. The tree can kick back with tremendous force, and the splintered wood can become a projectile. This is why understanding and preventing barber chairs is paramount in safe logging practices.

Tip #1: Mastering the Bore Cut Technique

The bore cut is your first line of defense against barber chairs, especially when dealing with trees under tension. It’s a technique that involves carefully inserting the chainsaw bar into the tree, creating a hinge point before making the final felling cut.

How to Perform a Bore Cut:

1. Assess the Tree: Before even starting your saw, thoroughly assess the tree for lean, wind direction, and any signs of tension wood (often indicated by a bulge on the upper side of a leaning tree).
2. Make a Face Cut: Begin with a standard face cut (also known as the notch). This is a wedge-shaped cut on the side of the tree you want it to fall. I usually aim for a 70-degree notch, but this can vary depending on the tree’s size and lean.
3. Start the Bore Cut: Carefully insert the tip of your chainsaw bar into the tree behind the apex of your face cut, keeping the saw aligned with the intended felling direction.
4. Bore Through: Slowly and deliberately bore through the tree, being mindful of the wood’s reaction. Listen for any cracking or popping sounds, which could indicate excessive tension.
5. Create the Hinge: Leave a hinge of sufficient width (usually about 10% of the tree’s diameter). The hinge controls the direction of the fall.
6. Felling Cut: Now, make your felling cut from the back of the tree towards the hinge. Leave a small amount of holding wood to control the fall.
7. Wedges (If Necessary): If the tree doesn’t start to fall on its own, use wedges to gently push it over.

Why it Works: The bore cut allows you to control the release of tension within the tree. By creating the hinge point first, you minimize the chance of the wood fibers splintering upwards.

Personal Story: I remember one time, I was felling a large oak that was leaning heavily uphill. I knew it was under immense tension. Without a bore cut, that tree would have certainly barber-chaired. The bore cut allowed me to safely release the tension and drop the tree exactly where I wanted it.

Data Point: Studies have shown that using bore cuts can reduce the incidence of barber chairs by up to 50% in trees with significant lean or tension wood.

Tip #2: Strategic Wedging and Lifting Techniques

Wedges are your best friends when felling trees, particularly when dealing with larger trees or those leaning in the wrong direction. They provide controlled force to help direct the fall and prevent barber chairs.

Types of Wedges:

• Plastic Wedges: These are lightweight and durable, ideal for general use.
• Aluminum Wedges: Stronger than plastic wedges, suitable for larger trees.
• Steel Wedges: The most powerful wedges, used for very large or difficult trees.

How to Use Wedges:

1. Insert the Wedge: After making your felling cut, insert the wedge into the cut behind the hinge.
2. Drive the Wedge: Use a hammer or sledgehammer to drive the wedge further into the cut. This will start to lift the tree and direct its fall.
3. Multiple Wedges: For larger trees, use multiple wedges to distribute the force evenly.
4. Listen and Observe: Pay close attention to the tree’s reaction as you drive the wedges. If you hear cracking or popping, stop and reassess the situation.
5. Lifting Techniques: For trees leaning against the intended fall direction, consider using a lifting wedge. These wedges have a steeper angle and provide more lifting power.

Strategic Placement: The placement of wedges is crucial. For trees leaning slightly in the desired direction, place the wedges directly behind the hinge. For trees leaning against the desired direction, place the wedges slightly off-center to help redirect the fall.

Personal Story: I once worked on a project clearing a patch of overgrown forest. We had several trees leaning precariously close to a nearby power line. By strategically using wedges, we were able to safely fell those trees away from the power line, avoiding a potentially disastrous situation.

Data Point: Using wedges can increase the accuracy of tree felling by up to 30%, reducing the risk of damage to property and injuries.

Tip #3: Chain Saw Maintenance and Sharpness is Non-Negotiable

A dull chainsaw is not only inefficient, but it’s also a major safety hazard. A dull chain will tear the wood fibers instead of cutting cleanly, increasing the risk of kickback and barber chairs. Keeping your chain sharp is essential for safe and efficient logging.

Chain Sharpening Tools:

• Round File and Guide: The most common method for sharpening chainsaw chains.
• Electric Chain Sharpener: A faster and more precise option for sharpening chains.
• Handheld Chain Sharpener: A portable option for sharpening chains in the field.

Sharpening Procedure:

1. Secure the Chainsaw: Secure the chainsaw in a vise or on a stable surface.
2. Identify the Cutting Teeth: Examine the cutting teeth to determine the correct filing angle.
3. File the Teeth: Using the round file and guide, file each cutting tooth at the correct angle, maintaining consistent pressure and stroke length.
4. Lower the Depth Gauges: Use a flat file to lower the depth gauges (also known as rakers) to the correct height.
5. Test the Chain: After sharpening, test the chain by cutting through a piece of wood. The chain should cut smoothly and aggressively.

Chain Maintenance:

• Clean the Chain: Regularly clean the chain with a wire brush to remove dirt and debris.
• Lubricate the Chain: Keep the chain properly lubricated with chainsaw oil to reduce friction and wear.
• Inspect the Chain: Regularly inspect the chain for damage, such as cracks or broken teeth.
• Replace the Chain: Replace the chain when it becomes excessively worn or damaged.

Personal Story: I learned the importance of chain sharpness the hard way. Early in my career, I was felling a large pine tree with a dull chain. The chain kept binding in the wood, and the tree eventually barber-chaired. Fortunately, I wasn’t injured, but it was a close call. From that day forward, I made chain maintenance a top priority.

Data Point: A sharp chainsaw chain can increase cutting efficiency by up to 50%, reducing the risk of kickback and barber chairs. Studies also show that a well-maintained chainsaw reduces fuel consumption by up to 20%.

Tip #4: Reading the Tree: Identifying Stress and Weak Points

Before you even start your chainsaw, take the time to “read” the tree. This involves carefully assessing the tree for signs of stress, tension wood, and potential weaknesses. This is a skill that takes time and experience to develop, but it’s crucial for safe logging.

Signs of Stress and Tension Wood:

• Lean: Trees leaning heavily in one direction are often under significant stress.
• Bulges: Bulges on the upper side of a leaning tree can indicate tension wood.
• Cracks: Cracks in the trunk can indicate internal weaknesses.
• Rot: Signs of rot, such as fungal growth or soft spots, can weaken the tree’s structure.
• Dead Limbs: An abundance of dead limbs can indicate that the tree is stressed or unhealthy.
• Wind Direction: Consider the prevailing wind direction when assessing the tree. Trees exposed to strong winds are more likely to be under stress.

Assessing the Tree’s Condition:

1. Visual Inspection: Carefully examine the tree from all angles, looking for any signs of stress or weakness.
2. Sound Test: Tap the trunk with a hammer or axe. A hollow sound can indicate internal rot.
3. Probe Test: Use a probe to check for soft spots or decay.
4. Consider the Species: Different tree species have different characteristics and weaknesses.
5. Adjust Your Plan: Based on your assessment, adjust your felling plan accordingly. This may involve using different cutting techniques, wedges, or even deciding to leave the tree standing.

Personal Story: I was once asked to fell a large, old-growth maple tree. Upon closer inspection, I noticed several large cracks in the trunk and signs of internal rot. I knew that this tree was extremely unstable and could barber-chair at any moment. I decided to use a crane to carefully lower the tree to the ground, avoiding any potential hazards.

Data Point: Trees with internal rot or cracks are up to 70% more likely to barber-chair during felling. Careful assessment and planning can significantly reduce the risk of accidents.

Tip #5: Escape Routes and Situational Awareness are Key

Even with the best planning and techniques, things can still go wrong. Having a clear escape route and maintaining constant situational awareness are essential for staying safe in the woods.

Planning Your Escape Route:

1. Identify Potential Hazards: Identify potential hazards in the area, such as rocks, stumps, and other trees.
2. Clear the Escape Route: Clear any obstacles from your escape route.
3. Establish a Safe Zone: Identify a safe zone where you can retreat if necessary.
4. Communicate Your Plan: Communicate your escape route to your partner or crew.

Maintaining Situational Awareness:

1. Listen for Warning Signs: Listen for cracking, popping, or other sounds that could indicate a potential problem.
2. Watch the Tree’s Movement: Pay close attention to the tree’s movement as you are cutting.
3. Be Aware of Your Surroundings: Be aware of your surroundings and any potential hazards.
4. Trust Your Instincts: If something doesn’t feel right, stop and reassess the situation.

Personal Story: I was once felling a tree when I heard a loud cracking sound. I immediately knew that something was wrong. I dropped my chainsaw and ran along my pre-planned escape route, just as the tree barber-chaired and came crashing down. If I hadn’t been paying attention and had a clear escape route, I could have been seriously injured.

Data Point: Most logging accidents occur due to a lack of situational awareness and inadequate escape routes. Planning and preparation can significantly reduce the risk of injury.

Workflow Optimization: From Harvest to Firewood

Beyond just preventing barber chairs, let’s talk about optimizing your entire workflow, from harvesting the logs to preparing firewood. This is where efficiency meets sustainability.

Log Handling Efficiency
