Chainsaw ArboristSite Tips (5 Pro Cutting Techniques)

As the crisp autumn air begins to bite and the leaves blaze in their final glory, my thoughts invariably turn to one thing: firewood. The satisfying scent of freshly cut wood, the rhythmic roar of the chainsaw, and the promise of a warm hearth on a cold winter’s night – these are the things that make this time of year truly special for me.

But being ready for winter isn’t just about stacking logs; it’s about mastering the art of efficient and safe wood processing. Over the years, I’ve learned a thing or two about using a chainsaw effectively, particularly when dealing with the challenges of tree work. That’s why I want to share five pro cutting techniques that I’ve found invaluable, especially in arborist-type situations. These tips, honed through years of experience and a healthy dose of trial and error, will help you work smarter, not harder, and stay safe while you’re at it.

Chainsaw ArboristSite Tips: 5 Pro Cutting Techniques for Efficient and Safe Wood Processing

Let’s dive right in. These techniques aren’t just theoretical; they’re born from real-world situations, from felling tricky trees to limbing branches in tight spots. I’ll break down each technique, explain why it works, and offer practical advice on how to implement it in your own projects.

1. Mastering the Bore Cut: Precision and Control in Tight Spots

The bore cut, also known as a plunge cut, is a game-changer when you’re working with trees that have internal tension or are in awkward positions. It allows you to control the direction of the cut and prevent pinching, which can be a real headache (and potentially dangerous).

What is a Bore Cut?

Essentially, a bore cut involves using the tip of your chainsaw bar to create a hole, or bore, into the wood before completing the cut. This relieves internal stresses and allows you to guide the cut precisely.

Why Use a Bore Cut?

• Prevent Pinching: When wood is under tension, it can pinch the chainsaw bar, making it difficult to control and potentially causing kickback. The bore cut relieves this tension before the final cut is made.
• Directional Control: By controlling the entry point and direction of the bore, you can precisely guide the cut, which is particularly useful when felling trees or limbing branches in confined spaces.
• Improved Safety: Reducing the risk of pinching and kickback makes the bore cut a safer option than simply cutting straight through the wood.

How to Perform a Bore Cut (Step-by-Step)

1. Stance and Stability: Position yourself with a wide, stable stance. Ensure you have a clear escape route should anything go wrong.
2. Initial Cut: Begin with a small, shallow cut on the side of the wood where you want to start the bore. This provides a stable entry point for the chainsaw.
3. Engage the Tip: Carefully angle the tip of the chainsaw bar into the wood at the point where you want to create the bore. Use a slow, controlled motion.
4. Bore Through: As the tip penetrates the wood, gradually increase the pressure while maintaining a steady speed. Keep the chainsaw running at a consistent RPM.
5. Complete the Cut: Once the bore is complete, use the upper or lower edge of the bar to finish the cut in the desired direction.

My Personal Experience:

I remember one particularly challenging job where I had to remove a large oak branch that was overhanging a house. The branch was under significant tension, and I knew that a straight cut would likely result in pinching and potential damage to the house. I used the bore cut technique to carefully relieve the tension and guide the branch away from the house. It worked like a charm, and I was able to remove the branch safely and efficiently.

Data Point: Studies have shown that using a bore cut can reduce the risk of chainsaw kickback by up to 30% compared to traditional cutting methods.

Wood Species Consideration: Hardwoods like oak and maple are more prone to pinching than softwoods like pine and fir. The bore cut is especially useful when working with these denser, more reactive woods.

2. The Hinge Cut: Felling Trees with Precision and Predictability

The hinge cut is a crucial technique for felling trees safely and predictably. By creating a hinge of uncut wood, you can control the direction in which the tree falls, minimizing the risk of damage to property or injury to yourself.

What is a Hinge Cut?

The hinge cut involves making a series of cuts in a specific pattern to leave a section of uncut wood, the “hinge,” which guides the tree’s fall.

Why Use a Hinge Cut?

• Directional Control: The hinge acts as a pivot point, allowing you to steer the tree as it falls.
• Safety: By controlling the direction of the fall, you can minimize the risk of the tree falling in an unexpected direction, potentially causing damage or injury.
• Predictability: The hinge cut makes the felling process more predictable, allowing you to plan your work more effectively.

How to Perform a Hinge Cut (Step-by-Step)

1. Planning and Assessment: Before making any cuts, carefully assess the tree, its lean, and the surrounding environment. Identify the desired direction of fall and clear any obstacles in the path.
2. Notch Cut: Begin by making a notch cut on the side of the tree facing the desired direction of fall. The notch should be about 1/3 of the tree’s diameter and angled at approximately 45 degrees.
3. Back Cut: On the opposite side of the tree, make a back cut that is level with the base of the notch. Leave a section of uncut wood, the “hinge,” between the back cut and the notch. The hinge should be about 1/10 of the tree’s diameter.
4. Wedges (Optional): If the tree is leaning in the wrong direction or if you need extra control, insert wedges into the back cut to help push the tree in the desired direction.
5. Final Push: Once the hinge is properly formed, give the tree a final push using a felling lever or by striking the back of the tree with a sledgehammer.

My Personal Experience:

I once had to fell a large pine tree that was leaning precariously towards a power line. The situation was tense, as any miscalculation could have resulted in a power outage or, worse, electrocution. I meticulously planned the hinge cut, using wedges to ensure the tree fell away from the power line. It was a nerve-wracking experience, but the hinge cut worked perfectly, and the tree fell exactly where I wanted it to.

Data Point: According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of logging accidents. Using a hinge cut can significantly reduce the risk of these accidents.

Wood Species Consideration: The size and density of the hinge should be adjusted based on the species of wood. Softer woods like pine require a larger hinge than hardwoods like oak.

3. The Limbing Cut: Efficient and Safe Branch Removal

Limbing, the process of removing branches from a felled tree, can be a tedious and potentially dangerous task. Using proper limbing techniques can significantly improve efficiency and reduce the risk of injury.

What is a Limbing Cut?

The limbing cut involves removing branches from a felled tree in a systematic and safe manner.

Why Use Proper Limbing Techniques?

• Efficiency: Proper limbing techniques can significantly speed up the process of branch removal.
• Safety: Limbing can be dangerous due to the potential for branches to spring back or roll the log. Using proper techniques minimizes these risks.
• Reduced Fatigue: Working efficiently reduces fatigue, which can lead to errors and accidents.

How to Perform a Limbing Cut (Step-by-Step)

1. Assess the Branches: Before starting, assess the branches and identify any that are under tension or are likely to spring back when cut.
2. Cut from the Base to the Tip: Start by cutting the branches closest to the base of the tree and work your way towards the tip. This prevents the log from rolling and pinning you.
3. Cut on the Compression Side: When cutting branches under tension, cut on the compression side first. This will prevent the branch from pinching the chainsaw bar and potentially causing kickback.
4. Use a Supporting Cut: For larger branches, use a supporting cut to prevent the bark from tearing. Make a small cut on the underside of the branch before completing the cut from the top.
5. Maintain a Safe Distance: Keep a safe distance from the log and any branches that are under tension.

My Personal Experience:

I used to waste so much time and energy limbing trees using haphazard techniques. I’d often get pinched by branches or have the log roll on me. One day, an old logger showed me the proper way to limb, and it completely changed my approach. By systematically working from the base to the tip and using supporting cuts, I was able to limb trees much faster and with far less effort.

Data Point: A study by the Forest Resources Association found that proper limbing techniques can increase productivity by up to 25%.

Wood Species Consideration: The limbing techniques used should be adjusted based on the species of wood. For example, hardwoods with dense branches may require more supporting cuts than softwoods.

4. The Cant Hook Leverage: Moving and Positioning Logs with Ease

Moving and positioning logs can be back-breaking work, especially when dealing with large or heavy pieces. A cant hook is an invaluable tool for improving leverage and making this task much easier.

What is a Cant Hook?

A cant hook is a long-handled lever with a pivoting hook that is used to grip and rotate logs.

Why Use a Cant Hook?

• Improved Leverage: The long handle of the cant hook provides significant leverage, making it easier to move and rotate logs.
• Reduced Strain: Using a cant hook reduces the strain on your back and arms, minimizing the risk of injury.
• Increased Efficiency: A cant hook allows you to move and position logs much faster than you could by hand.

How to Use a Cant Hook (Step-by-Step)

1. Position the Hook: Place the hook of the cant hook over the log, ensuring that it is securely gripping the wood.
2. Apply Leverage: Using the long handle of the cant hook, apply leverage to rotate or move the log in the desired direction.
3. Maintain Control: Keep a firm grip on the handle and maintain control of the log as you move it.
4. Reposition as Needed: Reposition the hook as needed to continue moving the log in the desired direction.

My Personal Experience:

Before I started using a cant hook, I would struggle to move even relatively small logs. My back would ache, and I’d often end up exhausted. Once I invested in a good cant hook, it was like night and day. I could easily roll and position logs that I previously couldn’t even budge. It saved me so much time and energy, and it significantly reduced the strain on my body.

Data Point: Studies have shown that using a cant hook can reduce the amount of force required to move a log by up to 50%.

Wood Species Consideration: The size and type of cant hook used should be adjusted based on the size and weight of the logs being moved. Hardwoods like oak require a larger, more robust cant hook than softwoods like pine.

5. Chain Maintenance: Keeping Your Chainsaw Running Smoothly and Safely

A dull chainsaw is not only inefficient but also dangerous. Maintaining your chainsaw chain is essential for ensuring optimal performance and safety.

Why is Chain Maintenance Important?

• Improved Cutting Efficiency: A sharp chain cuts through wood much faster and with less effort.
• Reduced Kickback: A dull chain is more likely to kick back, which can cause serious injury.
• Extended Chain Life: Regular maintenance can extend the life of your chainsaw chain, saving you money in the long run.
• Reduced Stress on the Saw: A sharp chain reduces the stress on the chainsaw engine, prolonging its life.

How to Maintain Your Chainsaw Chain (Step-by-Step)

1. Sharpen the Chain Regularly: Sharpen the chain after every few hours of use, or whenever you notice that it is becoming dull. Use a chainsaw file or a chain grinder to sharpen the cutters.
2. Check the Depth Gauges: Check the depth gauges (also known as rakers) and file them down as needed. The depth gauges control the amount of wood that each cutter takes, and they should be slightly lower than the cutters.
3. Clean the Chain: Clean the chain regularly to remove dirt, sawdust, and pitch. Use a wire brush or a solvent to clean the chain.
4. Lubricate the Chain: Lubricate the chain regularly with chainsaw bar oil. The oil reduces friction and helps to keep the chain cool.
5. Inspect the Chain: Inspect the chain regularly for damage, such as cracks, broken cutters, or loose rivets. Replace the chain if you find any damage.

My Personal Experience:

I used to neglect my chainsaw chain, thinking that sharpening was a waste of time. I’d run the saw until it was so dull that it would barely cut through wood. One day, I had a close call when my dull chain kicked back and nearly hit me in the face. That was a wake-up call. I started sharpening my chain regularly and maintaining it properly. The difference was incredible. The saw cut through wood like butter, and I felt much safer.

Data Point: Studies have shown that a sharp chainsaw chain can reduce cutting time by up to 50% compared to a dull chain.

Wood Species Consideration: The frequency of chain sharpening should be adjusted based on the species of wood being cut. Hardwoods like oak dull the chain faster than softwoods like pine. Also, cutting dirty wood will dull a chain almost immediately.

Additional Tips for Safe and Efficient Wood Processing

Beyond these five pro cutting techniques, here are a few additional tips that I’ve found helpful over the years:

• Wear Proper Safety Gear: Always wear proper safety gear, including a helmet, eye protection, hearing protection, gloves, and chaps.
• Use the Right Tool for the Job: Use the right chainsaw for the job. A small chainsaw is fine for limbing, but a larger chainsaw is needed for felling trees.
• Keep Your Chainsaw Clean: Keep your chainsaw clean and well-maintained. A clean chainsaw runs more efficiently and is less likely to break down.
• Take Breaks: Take breaks regularly to avoid fatigue. Fatigue can lead to errors and accidents.
• Get Training: If you’re new to chainsaw use, get training from a qualified instructor.
