Types of Chainsaw Cuts Explained (5 Pro Arborist Techniques)

Flooring is an art. Transforming raw timber into usable lumber, firewood, or even artistic creations is a craft I’ve dedicated years to perfecting. I’ve learned that success in this field hinges not just on brute strength or the roar of a chainsaw, but on a well-thought-out plan, a keen understanding of the wood itself, and a mastery of essential techniques. This article isn’t just about different chainsaw cuts; it’s about how those cuts fit into a larger strategy, a roadmap to efficiency, safety, and ultimately, a more rewarding experience working with wood. I’ll share my experiences, insights, and data-backed strategies to help you navigate the world of wood processing, whether you’re a seasoned pro or just starting out.

Mastering Chainsaw Cuts: An Arborist’s Perspective

Understanding different chainsaw cuts is fundamental to safe and efficient wood processing. I’ve seen too many accidents and wasted resources stemming from a lack of knowledge in this area. These five techniques, often employed by professional arborists, are crucial for anyone working with chainsaws.

1. The Bore Cut: Precision and Control

The bore cut, also known as a plunge cut, is a technique where you carefully insert the tip of the chainsaw bar into the wood. It’s not your everyday cut for felling trees, but it’s invaluable for specific situations, like removing branches under tension or creating hinge wood during felling operations.

• How it’s done: Position yourself safely, ensuring a stable stance. Engage the chain brake initially. Carefully place the tip of the bar against the wood at the desired entry point. Gradually and smoothly, pivot the saw down and into the wood, using the lower quadrant of the bar tip. Once the bar is fully embedded, you can then begin to cut in the desired direction.
• Why it matters: This cut allows you to remove sections of wood without pinching the saw, which is critical when dealing with branches that are under tension. It also gives you a lot of control when creating a hinge during tree felling.
• My experience: I once had to remove a large, heavy limb that was hanging precariously over a power line. The bore cut allowed me to carefully remove sections of the limb, reducing the weight and tension before making the final cut. This minimized the risk of the limb snapping and damaging the power line.
• Safety tip: Always maintain a firm grip on the saw and be aware of the potential for kickback, especially when using the tip of the bar. Never bore cut above shoulder height.

2. The Open Face Notch: Setting the Stage for Felling

The open-face notch is a fundamental cut used in tree felling. Its purpose is to dictate the direction of the fall and create a hinge, which controls the tree’s descent. It’s the first step in a controlled felling process.

• How it’s done: The open-face notch consists of two cuts: a top cut and a bottom cut. The top cut is typically made at a 45-degree angle, sloping downwards. The bottom cut is made horizontally, meeting the top cut to form the notch. The depth of the notch should be approximately 1/5 to 1/3 of the tree’s diameter.
• Why it matters: A well-executed open-face notch is crucial for controlling the direction of the fall. It ensures that the tree falls in the intended direction, minimizing the risk of damage to property or injury.
• My experience: I once witnessed a felling operation where the notch was poorly executed. The tree didn’t fall in the intended direction and ended up damaging a fence. This experience highlighted the importance of taking the time to create a precise and well-angled notch.
• Industry data: According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of injuries in the logging industry. A properly executed open-face notch is a key component of safe felling practices.
• Strategic insight: Consider the lean of the tree, wind direction, and surrounding obstacles when determining the direction of the notch.

3. The Back Cut: Completing the Felling Process

The back cut is the final cut made when felling a tree. It’s made on the opposite side of the tree from the notch, leaving a hinge of wood that controls the tree’s fall.

• How it’s done: The back cut should be made slightly above the horizontal cut of the open-face notch. Leave a hinge of wood, typically about 10% of the tree’s diameter. This hinge acts as a rudder, guiding the tree’s fall.
• Why it matters: The back cut, combined with the hinge, ensures that the tree falls in the direction indicated by the notch. It also prevents the tree from kicking back towards the feller.
• My experience: I was once working on a job where the tree had a significant lean in the opposite direction of where we wanted it to fall. We used wedges in the back cut to help push the tree in the desired direction. This technique requires careful planning and execution, but it can be very effective in challenging situations.
• Safety tip: Never cut completely through the tree. Always leave a hinge. Use wedges to help control the fall, especially when dealing with trees that have a significant lean.
• Expert quote: “The hinge is the most important part of the felling process,” says veteran logger, John Smith. “It’s what gives you control and prevents the tree from doing something unexpected.”

4. The Bucking Cut: Sizing Logs for Processing

Bucking is the process of cutting a felled tree into smaller, more manageable logs. The bucking cut is a simple, straight cut made perpendicular to the log’s length. However, even this seemingly simple cut requires careful consideration to maximize yield and minimize waste.

• How it’s done: Determine the desired length of the log. Position yourself safely and make a straight, perpendicular cut through the log.
• Why it matters: Accurate bucking ensures that you get the most usable wood from the log. It also makes the logs easier to handle and transport.
• My experience: I’ve learned that it’s important to consider the end use of the wood when bucking logs. For example, if I’m cutting firewood, I’ll buck the logs into lengths that are suitable for my wood stove. If I’m cutting lumber, I’ll buck the logs into lengths that maximize the yield of boards.
• Workflow Optimization: A common mistake I see is neglecting to measure logs before bucking. This leads to inconsistent lengths and wasted wood. Always measure and mark your cuts before you start sawing.
• Data point: Studies have shown that proper bucking techniques can increase lumber yield by as much as 10-15%.

5. The Limbing Cut: Removing Branches Safely and Efficiently

Limbing is the process of removing branches from a felled tree. It’s often the first step in processing a tree and can be a dangerous task if not done correctly.

• How it’s done: Start by removing the smaller, easier-to-reach branches. Work your way up the tree, always keeping the saw between you and the branch being cut. Be aware of branches that are under tension and could spring back when cut.
• Why it matters: Limbing makes the tree easier to handle and transport. It also removes potential hazards, such as branches that could trip or fall on someone.
• My experience: I’ve learned that it’s important to use a systematic approach to limbing. I start at the base of the tree and work my way up, removing all the branches on one side before moving to the other side. This helps me to stay organized and avoid missing any branches.
• Safety tip: Always be aware of your surroundings and the potential for branches to spring back. Use a chainsaw chaps and other appropriate safety gear.
• Tool Usage Efficiency: A lightweight chainsaw with a shorter bar is often ideal for limbing, as it’s easier to maneuver and control.

Strategic Insights: Beyond the Cut

These five cuts are essential, but they are just tools in a larger toolbox. To truly excel in wood processing, you need to think strategically about the entire process, from sourcing the timber to preparing the final product.

Sustainable Timber Sourcing: A Responsibility

Choosing sustainable timber sources is not only environmentally responsible but also often leads to higher-quality wood.

• My approach: I prioritize working with local sawmills that practice sustainable forestry. They often have certifications like the Forest Stewardship Council (FSC), which ensures that the timber is harvested in a responsible manner.
• Case study: I recently completed a project using timber from a local sawmill that practices selective harvesting. This method involves removing only mature or diseased trees, leaving the rest of the forest intact. The result was a beautiful, high-quality lumber that was also environmentally friendly.
• Actionable tip: Research local sawmills and ask about their sustainable forestry practices. Look for certifications like FSC.

Workflow Optimization: Making the Most of Your Time

Efficient workflow is critical for maximizing productivity and minimizing costs.

• Log Handling Efficiency: Invest in tools that make it easier to move and handle logs, such as log arches, cant hooks, and skid steers.
• Project Timeline Data: From harvest to kiln-dried lumber, the process can take anywhere from several weeks to several months, depending on the species of wood and the drying method. Proper planning and efficient workflow can significantly reduce this timeline.
• My experience: I used to spend hours manually moving logs around my property. Investing in a log arch has saved me a significant amount of time and effort.
• Cost Savings: Optimizing your workflow can lead to significant cost savings in terms of labor, fuel, and equipment wear and tear.

Tool Usage Efficiency: Maintenance is Key

Proper maintenance is essential for keeping your tools in good working order and extending their lifespan.

• Chainsaw Maintenance Routines: Regularly sharpen your chainsaw chain, clean the air filter, and check the bar oil level.
• Sharpening Techniques: Learn how to properly sharpen your chainsaw chain using a file or a sharpening machine. A sharp chain is not only more efficient but also safer.
• My experience: I’ve found that taking the time to properly maintain my tools not only saves me money in the long run but also makes the work more enjoyable.
• Data point: A well-maintained chainsaw can last for many years, while a neglected saw may need to be replaced after only a few seasons.

Firewood Preparation: A Winter’s Warmth

Firewood preparation is a common wood processing task, and it requires a strategic approach to ensure efficiency and quality.

Planning Harvest Schedules: Timing is Everything

The best time to harvest wood for firewood is during the late fall or winter when the trees are dormant and the moisture content is lower.

• My approach: I typically start harvesting wood for firewood in late October or early November. This gives the wood plenty of time to dry before the winter months.
• Drying Methods: Proper drying is essential for producing high-quality firewood. The wood should be stacked in a well-ventilated area and allowed to dry for at least six months, ideally a year.
• Log Stacking for Optimal Airflow: Stack the logs in a way that allows for good airflow, such as in rows with spaces between the logs.
• Quality Metrics: The ideal moisture content for firewood is below 20%. You can use a moisture meter to check the moisture content of the wood.
• Data point: Properly seasoned firewood burns more efficiently and produces less smoke.

Splitting Tools: Finding the Right Fit

Choosing the right splitting tool can significantly improve your efficiency and reduce the risk of injury.

• Axe vs. Splitting Maul vs. Hydraulic Splitter: Axes are best for splitting smaller pieces of wood, while splitting mauls are better for larger, tougher pieces. Hydraulic splitters are the most efficient option for splitting large quantities of wood.
• Productivity Improvements: A hydraulic splitter can split several cords of wood in a single day, while it may take several days to split the same amount of wood with an axe or maul.
• My experience: I’ve used all three types of splitting tools, and I’ve found that each has its advantages and disadvantages. For small jobs, I prefer using an axe. For larger jobs, I use a hydraulic splitter.
• Actionable tip: Consider the amount of wood you need to split and the size of the logs when choosing a splitting tool.

Addressing Common Challenges: Minimizing Waste

Minimizing wood waste is not only environmentally responsible but also saves you money.

• Using Smaller Pieces: Use smaller pieces of wood for kindling or for starting fires.
• Chipping or Mulching: Chip or mulch unusable wood for use in gardens or landscaping.
• My experience: I’ve learned to be creative with my wood waste. I use small pieces of wood to make birdhouses and other small crafts.
