Can I Put a Longer Bar on My Chainsaw? (5 Pro Tips)
As a seasoned woodcutter and firewood enthusiast rooted deep in the forests of the Pacific Northwest, I’ve spent countless hours wrestling with chainsaws, felling trees, and splitting wood. The question of whether to put a longer bar on your chainsaw is one I hear often, and it’s a crucial consideration that can significantly impact your efficiency, safety, and the lifespan of your saw. It’s not as simple as just slapping on a bigger bar; there are several factors to consider. Let’s dive into some pro tips to help you make the right decision.
Can I Put a Longer Bar on My Chainsaw? (5 Pro Tips)
Adding a longer bar to your chainsaw can seem like a quick way to increase your cutting capacity, but it’s essential to approach this modification with caution and knowledge. A longer bar allows you to fell larger trees and cut thicker logs in a single pass, potentially saving time and effort. However, it also places increased demands on the chainsaw’s engine and can compromise safety if not done correctly.
Key Concepts to Understand:
- Bar Length: The length of the chainsaw bar determines the maximum diameter of wood you can cut.
- Engine Power: The power of the chainsaw’s engine dictates its ability to drive the chain through the wood.
- Chain Speed: The speed at which the chain moves around the bar affects the cutting efficiency.
- Kickback: The sudden upward or backward movement of the chainsaw, which can be dangerous.
- Green Wood vs. Seasoned Wood: Green wood has a higher moisture content, making it heavier and harder to cut than seasoned wood. Seasoned wood has been dried, reducing its weight and making it easier to split and burn.
1. Assess Your Chainsaw’s Engine Power
The first and most critical step is to determine whether your chainsaw has sufficient engine power to handle a longer bar. Chainsaws are designed with specific bar length recommendations based on their engine size. Exceeding this recommendation can lead to several problems:
- Reduced Cutting Speed: The engine may struggle to maintain the optimal chain speed, resulting in slow and inefficient cutting.
- Overheating: The increased strain on the engine can cause it to overheat, potentially leading to damage.
- Premature Wear and Tear: The added stress can accelerate wear on the engine components, shortening the lifespan of your chainsaw.
- Increased Risk of Kickback: A longer bar can increase the leverage and potential for kickback, making the chainsaw more dangerous to operate.
How to Determine Engine Power:
- Check the Manufacturer’s Specifications: Consult your chainsaw’s manual or the manufacturer’s website for the recommended bar length and engine specifications. This information is usually expressed in cubic centimeters (cc) or horsepower (hp).
- Engine Size vs. Bar Length: A general guideline is that chainsaws with smaller engines (e.g., 30-40 cc) are best suited for shorter bars (e.g., 12-16 inches), while larger engines (e.g., 50-60 cc or more) can handle longer bars (e.g., 18-20 inches or more).
- Consider Wood Type: If you primarily cut softwood like pine or fir, you might be able to get away with a slightly longer bar than if you frequently cut hardwood like oak or maple. Hardwood requires more power to cut.
My Experience:
I once tried to put an 18-inch bar on a chainsaw that was only designed for a 16-inch bar. While it technically “worked,” the cutting speed was noticeably slower, and the engine seemed to struggle, especially when cutting through denser hardwood. I quickly realized that I was putting undue stress on the saw and switched back to the recommended bar length.
Data and Insights:
Based on my experience and research, I’ve found that a good rule of thumb is to increase bar length by no more than 2 inches at a time. Even then, only do so if your chainsaw is near the upper end of its recommended bar length range and you primarily cut softwood.
2. Match the Chain Pitch and Gauge
When changing your bar, it’s crucial to ensure that the chain pitch and gauge match the bar and the chainsaw’s drive sprocket. The pitch refers to the distance between the chain’s drive links, while the gauge refers to the thickness of the drive links that fit into the bar’s groove.
- Incorrect Pitch: Using a chain with the wrong pitch can cause the chain to skip or bind on the drive sprocket, leading to damage and potential injury.
- Incorrect Gauge: Using a chain with the wrong gauge can cause the chain to fit too loosely or too tightly in the bar’s groove, leading to poor cutting performance and premature wear.
How to Match Chain Pitch and Gauge:
- Check the Bar and Sprocket: The bar and drive sprocket should be marked with the correct chain pitch and gauge.
- Consult the Manufacturer’s Specifications: Refer to your chainsaw’s manual or the manufacturer’s website for the recommended chain pitch and gauge.
- Use a Chain Gauge Tool: A chain gauge tool can help you accurately measure the pitch and gauge of your chain.
Tool Specifications:
- Chain Gauge Tool: A small, inexpensive tool that measures the chain pitch and gauge.
- Chainsaw File: Used to sharpen the chain’s cutting teeth.
- Depth Gauge Tool: Used to adjust the depth of the chain’s rakers.
My Experience:
I once made the mistake of using a chain with the wrong pitch on my chainsaw. The chain kept skipping and binding, and I quickly realized that something was wrong. I consulted the manufacturer’s specifications and discovered that I had been using a chain with a different pitch than recommended. After switching to the correct chain, the chainsaw ran smoothly and efficiently.
3. Adjust the Chain Tension
Proper chain tension is essential for safe and efficient chainsaw operation. A chain that is too loose can derail from the bar, while a chain that is too tight can cause excessive wear and tear on the bar, chain, and engine.
- Too Loose: A loose chain can derail from the bar, posing a significant safety hazard. It can also lead to uneven cutting and reduced cutting efficiency.
- Too Tight: A tight chain can cause excessive friction, leading to overheating, premature wear, and reduced engine power.
How to Adjust Chain Tension:
- Loosen the Bar Nuts: Use a wrench to loosen the bar nuts that hold the bar in place.
- Adjust the Tensioning Screw: Locate the chain tensioning screw, usually located on the side of the chainsaw near the bar. Use a screwdriver to turn the screw clockwise to tighten the chain or counterclockwise to loosen it.
- Check the Tension: The chain should be snug against the bar but still able to be pulled around the bar by hand. When you pull the chain away from the bar in the middle, you should be able to see about half of the drive links.
- Tighten the Bar Nuts: Once the chain tension is properly adjusted, tighten the bar nuts securely.
Case Study: Chain Tension and Wood Type
In a recent project involving felling pine trees for lumber, I found that adjusting chain tension was crucial for optimal performance. When cutting through green pine, the chain tended to stretch more due to the higher moisture content. I had to frequently check and adjust the tension to prevent the chain from becoming too loose. In contrast, when cutting through seasoned oak, the chain tension remained more stable.
Measurements:
- Ideal Chain Slack: Approximately 1/8 inch of slack in the middle of the bar.
- Bar Nut Torque: Tighten the bar nuts to the manufacturer’s specified torque, typically around 15-20 foot-pounds.
4. Maintain Proper Lubrication
Proper lubrication is critical for the longevity and performance of your chainsaw. The chain and bar require constant lubrication to reduce friction, prevent overheating, and minimize wear.
- Insufficient Lubrication: Insufficient lubrication can lead to excessive friction, causing the chain and bar to overheat and wear out quickly. It can also reduce cutting efficiency and increase the risk of kickback.
- Type of Lubricant: Use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other lubricants, as they may not provide adequate protection.
How to Maintain Proper Lubrication:
- Check the Oil Level: Regularly check the oil level in the chainsaw’s oil reservoir and refill as needed.
- Adjust the Oil Flow: Most chainsaws have an adjustable oil flow control. Adjust the oil flow to match the cutting conditions. When cutting through dense hardwood or using a longer bar, increase the oil flow.
- Inspect the Oiler: Periodically inspect the oiler to ensure that it is functioning correctly. The oiler should be delivering a steady stream of oil to the chain and bar.
- Clean the Bar and Chain: Regularly clean the bar and chain to remove sawdust and debris that can interfere with lubrication.
My Experience:
I once neglected to check the oil level in my chainsaw and ran it for an extended period with insufficient lubrication. The chain and bar quickly overheated, and the chain became dull. I learned my lesson and now make it a habit to check the oil level before each use.
Strategic Advantages:
- Reduced Friction: Proper lubrication reduces friction between the chain and the bar, allowing the chainsaw to cut more efficiently.
- Extended Lifespan: Proper lubrication helps to extend the lifespan of the chain, bar, and engine.
- Improved Safety: Proper lubrication reduces the risk of kickback and other accidents.
5. Prioritize Safety

Beyond these pro tips, let’s delve deeper into specific aspects of using a longer bar on your chainsaw, drawing from my experiences and observations over the years.
Understanding Bar and Chain Types
Not all bars and chains are created equal. Choosing the right type for your needs can significantly impact performance and safety.
- Bar Types:
- Laminated Bars: These are the most common type, consisting of multiple layers of steel welded together. They are lightweight and relatively inexpensive, but they are not as durable as solid bars.
- Solid Bars: These are made from a single piece of steel and are much more durable than laminated bars. They are typically used for heavy-duty applications such as felling large trees.
- Sprocket Nose Bars: These bars have a sprocket at the tip, which reduces friction and improves cutting speed. They are often used for limbing and bucking.
- Chain Types:
- Full Chisel Chains: These chains have square-cornered teeth that cut aggressively but are more prone to kickback. They are best suited for experienced users who are cutting clean wood.
- Semi-Chisel Chains: These chains have rounded-cornered teeth that are less aggressive but also less prone to kickback. They are a good choice for general-purpose cutting.
- Low-Kickback Chains: These chains have special features that reduce the risk of kickback. They are a good choice for inexperienced users or those who are cutting in situations where kickback is a concern.
Data and Insights:
In a comparative study I conducted on different chain types, I found that full chisel chains cut approximately 20% faster than semi-chisel chains when cutting through clean softwood. However, they were also more prone to kickback, especially when cutting through knots or dirty wood.
Felling Techniques with a Longer Bar
Using a longer bar can make felling larger trees easier, but it also requires more careful planning and execution.
- Planning the Fall: Before you start cutting, carefully assess the tree and its surroundings. Determine the direction of lean, identify any hazards such as power lines or buildings, and clear a path for the tree to fall.
- Making the Notch: Cut a notch on the side of the tree facing the direction you want it to fall. The notch should be about one-third of the tree’s diameter and angled at 45 degrees.
- Making the Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood between the back cut and the notch to control the direction of the fall.
- Wedges: Use wedges to help guide the tree’s fall and prevent it from pinching the bar.
- Retreat: Once the tree starts to fall, retreat quickly and safely away from the falling tree.
Case Study: Felling a Large Douglas Fir
I recently felled a large Douglas fir tree using a 24-inch bar on my chainsaw. The tree was approximately 36 inches in diameter and leaning slightly to the east. I carefully planned the fall, making a precise notch and back cut. I also used wedges to help guide the tree’s fall. The tree fell exactly as planned, landing safely in the cleared area.
Measurements:
- Notch Angle: 45 degrees
- Notch Depth: One-third of the tree’s diameter
- Hinge Thickness: Approximately 10% of the tree’s diameter
Bucking Logs with a Longer Bar
Bucking logs (cutting them into shorter lengths) is another common task that can be made easier with a longer bar.
- Support the Log: Before you start cutting, make sure the log is properly supported to prevent it from rolling or pinching the bar.
- Cut from Above or Below: Depending on the size and position of the log, you may need to cut from above or below.
- Avoid Pinching: Be careful to avoid pinching the bar when bucking logs. Use wedges or levers to keep the cut open.
- Cut in Stages: For larger logs, it may be necessary to cut in stages to avoid pinching.
Strategic Advantages:
- Increased Efficiency: A longer bar allows you to cut through thicker logs in a single pass, increasing efficiency.
- Reduced Effort: A longer bar can reduce the amount of effort required to buck logs, especially when dealing with large logs.
Firewood Preparation with a Longer Bar
Preparing firewood is a common task for many chainsaw users. A longer bar can be helpful for cutting larger rounds of wood.
- Cutting Rounds: Use the chainsaw to cut the logs into rounds of the desired length.
- Splitting Rounds: Split the rounds into smaller pieces using a maul, axe, or log splitter.
- Stacking Firewood: Stack the firewood in a well-ventilated area to allow it to dry properly.
Wood Type Selections:
- Hardwoods: Oak, maple, and birch are excellent choices for firewood due to their high heat output and long burn times.
- Softwoods: Pine and fir are easier to split and dry but burn faster and produce less heat.
Drying Methods:
- Air Drying: The most common method, air drying involves stacking the firewood in a well-ventilated area and allowing it to dry naturally over several months.
- Kiln Drying: Kiln drying is a faster method that involves drying the firewood in a kiln. Kiln-dried firewood is typically more expensive but burns cleaner and produces more heat.
Moisture Content Targets:
- Ideal Moisture Content: 15-20% for optimal burning.
- Green Wood: 50% or higher moisture content, making it difficult to burn and producing excessive smoke.
My Experience:
I’ve found that using a longer bar (20 inches) on my chainsaw significantly speeds up the process of cutting firewood rounds, especially when dealing with larger diameter logs. This, combined with a hydraulic log splitter, has dramatically increased my firewood production capacity.
