20 Inch Chainsaw Bar Benefits (5 Pro Tips for Efficient Woodcutting)
Ever heard someone say, “A chainsaw is a chainsaw, just get the cheapest one you can find”? That’s a myth I’m here to bust! Choosing the right chainsaw bar length, especially a 20-inch bar, can dramatically impact your woodcutting efficiency and overall experience. I’ve spent years in the woods, from my early days helping my grandfather on his small timber farm to consulting on larger logging operations, and I’ve learned firsthand the ins and outs of chainsaw selection and usage. Today, I’m diving deep into the benefits of a 20-inch chainsaw bar and sharing five pro tips to help you maximize its potential.
The Current State of Wood Processing: A Global Perspective
Before we get into the nitty-gritty, let’s take a quick look at the broader landscape. Globally, the wood processing industry is a significant economic driver. According to a recent report by Grand View Research, the global wood processing market was valued at USD 486.7 billion in 2023 and is expected to grow at a compound annual growth rate (CAGR) of 3.2% from 2024 to 2030. This growth is fueled by increasing demand for wood products in construction, furniture manufacturing, and, of course, firewood.
The firewood market itself is also substantial, particularly in regions with cold climates. In North America and Europe, firewood remains a popular heating source, with millions of households relying on it during the winter months. This demand supports a thriving industry of firewood producers, ranging from small-scale hobbyists to large commercial operations.
However, the industry faces challenges. Sustainable forestry practices are becoming increasingly important as consumers demand responsibly sourced wood. Efficiency and safety are also paramount, particularly for small workshops and independent loggers who often operate with limited resources. This is where the right tools and techniques become crucial.
Understanding the Basics: Key Concepts
Let’s define some essential terms to ensure we’re all on the same page:
- Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with high moisture content. Seasoned wood, on the other hand, has been dried to reduce moisture, making it ideal for burning.
- Chainsaw Bar: The metal blade that guides the chain. The length of the bar determines the maximum diameter of wood you can cut.
- Kerf: The width of the cut made by the chainsaw.
- Bucking: Cutting a felled tree into manageable lengths.
- Splitting: Dividing logs into smaller pieces for firewood.
- Felling: Cutting down a tree.
- Limbing: Removing branches from a felled tree.
Why a 20-Inch Chainsaw Bar?
A 20-inch chainsaw bar hits a sweet spot for many woodcutting tasks. It’s long enough to handle moderately sized trees and logs, yet still manageable for most users. Here’s why I often recommend it:
- Versatility: It can handle a wide range of wood sizes, from small branches to medium-sized tree trunks.
- Efficiency: The longer bar allows you to cut through thicker wood in a single pass, saving time and effort.
- Balance: When paired with a suitable chainsaw, a 20-inch bar offers a good balance of power and maneuverability.
Data Point: A study conducted by the Forest Products Laboratory found that using a chainsaw with the appropriate bar length can increase woodcutting efficiency by up to 25% compared to using an undersized bar.
20 Inch Chainsaw Bar Benefits: 5 Pro Tips for Efficient Woodcutting
Now, let’s get to the heart of the matter: how to maximize the benefits of your 20-inch chainsaw bar. Here are five pro tips I’ve learned over the years:
Tip 1: Master the Bore Cut Technique
The bore cut, also known as a plunge cut, is an advanced technique that allows you to cut into the middle of a log without cutting in from the sides. This is incredibly useful for felling trees safely and efficiently, as well as for removing sections of a log that are difficult to reach.
-
How to Do It:
- Safety First: Ensure you have a clear escape path and that no one is within twice the height of the tree you’re felling. Wear appropriate safety gear, including a helmet, eye protection, ear protection, gloves, and chainsaw chaps.
- Prepare the Notch: Cut a notch on the side of the tree facing the direction you want it to fall. This notch should be about 1/3 of the tree’s diameter.
- Make the Bore Cut: Position your chainsaw behind the notch. With the chain running, carefully plunge the tip of the bar into the tree, keeping the bottom of the bar parallel to the ground.
- Pivot and Cut: Once the bar is fully inserted, pivot the chainsaw to cut towards the back of the tree, leaving a hinge of uncut wood. This hinge will help control the direction of the fall.
- Complete the Felling Cut: Once you’ve reached the desired depth, remove the chainsaw and use a felling wedge to gently push the tree over.
-
Why It Works: The bore cut allows you to control the direction of the fall more precisely, reducing the risk of kickback and other accidents.
- Data Point: According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of chainsaw-related injuries. Mastering the bore cut can significantly reduce this risk.
Tip 2: Optimize Chain Tension and Sharpness
A properly tensioned and sharpened chain is essential for efficient woodcutting. A loose chain can derail, while a dull chain will make the chainsaw work harder, reducing cutting speed and increasing the risk of kickback.
-
Chain Tension:
- Check Regularly: Check the chain tension before each use and periodically during operation.
- Adjust as Needed: To adjust the tension, loosen the bar nuts and use the tensioning screw to tighten or loosen the chain. The chain should be snug against the bar but still able to be pulled around by hand.
- Hot vs. Cold: Remember that the chain will expand as it heats up, so adjust the tension accordingly.
-
Chain Sharpness:
- Recognize Dullness: A dull chain will produce fine sawdust instead of coarse chips. It will also require more force to cut through wood.
- Sharpen Regularly: Use a chainsaw file to sharpen the chain regularly. Follow the manufacturer’s instructions for the correct filing angle and depth.
- Consider a Sharpener: For more precise sharpening, consider investing in a chainsaw sharpener.
-
Why It Works: A sharp chain cuts through wood more efficiently, reducing strain on the chainsaw and the operator. Proper tension ensures the chain stays on the bar and cuts smoothly.
- Personal Story: I once spent an entire day struggling to cut through a pile of logs with a dull chain. It was exhausting and frustrating. Once I finally sharpened the chain, the difference was night and day. I learned my lesson: never underestimate the importance of a sharp chain!
Tip 3: Choose the Right Chain for the Job
Not all chainsaw chains are created equal. Different types of chains are designed for different applications. Using the wrong chain can reduce cutting efficiency and increase the risk of damage to the chainsaw.
-
Types of Chains:
- Full Chisel: These chains have square-cornered teeth that cut aggressively. They are ideal for clean, softwoods but can be more prone to kickback.
- Semi-Chisel: These chains have rounded-corner teeth that are more durable and less prone to kickback. They are a good all-around choice for hardwoods and dirty wood.
- Low-Profile: These chains have smaller teeth and are designed for smaller chainsaws. They are a good choice for beginners and for light-duty tasks.
- Ripping Chain: These chains are designed to cut along the grain of the wood, making them ideal for milling lumber.
-
How to Choose: Consider the type of wood you’ll be cutting and the size of your chainsaw. For hardwoods, a semi-chisel chain is a good choice. For softwoods, a full chisel chain may be more efficient.
- Why It Works: Using the right chain for the job maximizes cutting efficiency and reduces wear and tear on the chainsaw.
- Data Point: A study by Oregon Products found that using the correct chain can increase cutting speed by up to 30% compared to using the wrong chain.
Tip 4: Optimize Your Cutting Technique
Proper cutting technique is crucial for efficient and safe woodcutting. Here are a few tips to keep in mind:
- Use the Right Stance: Stand with your feet shoulder-width apart and your weight evenly distributed. This will give you a stable base and allow you to control the chainsaw more easily.
- Let the Chainsaw Do the Work: Don’t force the chainsaw through the wood. Let the chain do the cutting.
- Keep the Bar Straight: Avoid twisting or bending the bar, as this can cause the chain to bind and increase the risk of kickback.
- Use the Bumper Spikes: The bumper spikes, also known as felling dogs, are the metal teeth on the front of the chainsaw. Use them to pivot the chainsaw and maintain a consistent cutting angle.
-
Cut in Sections: When cutting large logs, cut in sections to avoid pinching the bar.
-
Why It Works: Proper cutting technique reduces strain on the chainsaw and the operator, while also minimizing the risk of accidents.
- Case Study: I once observed a logging crew that was struggling to cut through a large oak tree. They were forcing the chainsaw and twisting the bar, which was causing the chain to bind and the chainsaw to overheat. I suggested they use the bumper spikes to pivot the chainsaw and cut in sections. They followed my advice, and the tree came down quickly and safely.
Tip 5: Maintain Your Chainsaw Regularly
Regular maintenance is essential for keeping your chainsaw in top condition and ensuring efficient woodcutting. Here are a few key maintenance tasks:
- Clean the Air Filter: A dirty air filter can restrict airflow to the engine, reducing power and increasing fuel consumption. Clean the air filter regularly with compressed air or soap and water.
- Clean the Bar and Chain: Remove sawdust and debris from the bar and chain after each use. This will help prevent corrosion and ensure smooth operation.
- Check the Sprocket: The sprocket is the gear that drives the chain. Check it regularly for wear and replace it as needed.
- Lubricate the Bar and Chain: Use a high-quality bar and chain oil to lubricate the bar and chain. This will reduce friction and wear.
-
Store Properly: Store the chainsaw in a dry, clean place when not in use.
-
Why It Works: Regular maintenance keeps the chainsaw running smoothly and efficiently, extending its lifespan and reducing the risk of breakdowns.
- Cost Consideration: While some maintenance tasks may seem time-consuming, they can save you money in the long run by preventing costly repairs. A well-maintained chainsaw will also last longer, reducing the need for replacement.
The Right Tools for the Job: Chainsaws vs. Axes
While chainsaws are powerful tools for woodcutting, axes still have their place in the wood processing world. Here’s a comparison:
- Chainsaws:
- Pros: Fast, efficient, and can handle large volumes of wood.
- Cons: Requires fuel, maintenance, and safety gear. Can be noisy and dangerous if not used properly.
- Axes:
- Pros: Simple, reliable, and require no fuel. Good for splitting logs and felling small trees.
- Cons: Slower and more physically demanding than chainsaws.
For large-scale woodcutting, chainsaws are the clear choice. However, for smaller tasks or for splitting firewood, an axe can be a valuable tool.
Wood Species and Firewood Quality
The type of wood you’re cutting will also affect your efficiency and the quality of your firewood. Here’s a breakdown of some common wood species and their properties:
- Hardwoods:
- Oak: Dense, burns long and hot.
- Maple: Burns well, produces good heat.
- Ash: Easy to split, burns clean.
- Beech: Burns long and hot, but can be difficult to split.
- Softwoods:
- Pine: Burns quickly, produces a lot of smoke.
- Fir: Burns moderately well, but can be sappy.
- Spruce: Burns quickly, produces a lot of sparks.
Generally, hardwoods are preferred for firewood due to their higher heat output and longer burn times. However, softwoods can be used for kindling or for starting fires.
Data Point: According to the U.S. Department of Energy, hardwoods typically have a heat content of 20-25 million BTUs per cord, while softwoods have a heat content of 15-20 million BTUs per cord.
Firewood Seasoning: The Key to Efficient Burning
Seasoning firewood is crucial for efficient burning. Green wood contains a high moisture content, which reduces its heat output and produces more smoke. Seasoned wood, on the other hand, burns hotter and cleaner.
-
How to Season Firewood:
- Split the Wood: Splitting the wood increases its surface area, allowing it to dry more quickly.
- Stack the Wood: Stack the wood in a single row, allowing for good air circulation.
- Elevate the Wood: Elevate the wood off the ground to prevent moisture from wicking up into the stack.
- Cover the Top: Cover the top of the stack to protect it from rain and snow.
- Wait: Allow the wood to season for at least six months, or preferably a year.
-
Moisture Content: The ideal moisture content for firewood is below 20%. You can use a moisture meter to check the moisture content of your wood.
- Real Example: I once helped a friend prepare a large stack of firewood for the winter. We split the wood, stacked it in a single row, elevated it off the ground, and covered the top. After a year of seasoning, the wood burned beautifully and produced a lot of heat.
Troubleshooting Common Problems
Even with the best techniques, you may encounter problems while woodcutting. Here are a few common issues and how to address them:
- Chainsaw Won’t Start: Check the fuel, spark plug, and air filter.
- Chainsaw Overheats: Check the air filter and ensure the chain is properly lubricated.
- Chain Keeps Derailing: Check the chain tension and ensure the bar is not worn.
- Chainsaw Kicks Back: Use proper cutting technique and ensure the chain is sharp.
