Key Concepts: Chainsaw Chain Anatomy and File Types

Before diving into specific file recommendations, it’s crucial to understand the basics of chainsaw chain anatomy and the different types of files available.

Chainsaw Chain Anatomy:

• Cutting Teeth (Cutters): These are the primary cutting elements of the chain. Each cutter consists of a top plate and a side plate, which form the cutting edge.
• Depth Gauges (Rakers): These control the depth of the cut taken by each cutter. They must be properly filed to ensure optimal cutting performance.
• Tie Straps: These connect the cutters and drive links, holding the chain together.
• Drive Links: These engage with the sprocket on the chainsaw, driving the chain around the bar.

File Types:

• Round Files: Used for sharpening the cutting edges of the cutters. The diameter of the file must match the chain’s pitch (the distance between three consecutive rivets divided by two). Common sizes range from 5/32″ to 7/32″.
• Flat Files: Used for filing the depth gauges.
• File Guides: These tools help maintain the correct filing angle and depth.
• Depth Gauge Tools: Used to check and adjust the height of the depth gauges.

Key Terms:

• Pitch: The size of the chain, typically expressed in inches (e.g., .325″, 3/8″).
• Gauge: The thickness of the drive links, which must match the bar’s groove width.
• Filing Angle: The angle at which the file is held relative to the cutter, typically marked on the file guide.
• Depth Gauge Height: The height of the depth gauge relative to the cutting edge of the cutter.
• Green Wood: Freshly cut wood with high moisture content.
• Seasoned Wood: Wood that has been allowed to dry, reducing its moisture content.

Step-by-Step Guide to Chainsaw Chain Sharpening

Sharpening a chainsaw chain is a skill that requires practice and attention to detail. Here’s a step-by-step guide to help you achieve optimal results:

Step 1: Safety First

• Wear gloves: Protect your hands from sharp teeth.
• Secure the chainsaw: Place the chainsaw in a vise or clamp it securely to a workbench.
• Disengage the chain brake: Ensure the chain can rotate freely.

Step 2: Inspect the Chain

• Look for damage: Check for broken or cracked teeth. Replace the chain if necessary.
• Identify the shortest cutter: This will be your reference point for sharpening all other cutters.

Step 3: Choose the Correct File Size

• Match the file to the chain pitch: Consult your chainsaw’s manual or the chain manufacturer’s specifications.

Step 4: Use a File Guide (Recommended)

• Select the correct angle: Most file guides have markings for different filing angles.
• Position the file guide: Place the file guide on the chain, aligning the file with the cutter.

Step 5: File the Cutters

• Maintain a consistent angle: Follow the markings on the file guide.
• File from the inside out: Stroke the file across the cutter, applying light pressure.
• Count the strokes: Use the same number of strokes for each cutter to ensure consistent sharpening.
• Sharpen all cutters: Work your way around the chain, sharpening each cutter in turn.

Step 6: File the Depth Gauges (Rakers)

• Use a flat file and a depth gauge tool: The depth gauge tool will indicate the correct height.
• File the depth gauges: File the depth gauges until they are flush with the depth gauge tool.
• Round off the front of the depth gauges: This will prevent the chain from grabbing or chattering.

Step 7: Check Your Work

• Inspect the cutters: Ensure that all cutters are sharp and have a consistent angle.
• Check the depth gauges: Verify that the depth gauges are at the correct height.

Step 8: Test the Chain

• Start the chainsaw: Run the chainsaw briefly and observe the cutting performance.
• Adjust as needed: If the chain is not cutting smoothly, repeat the sharpening process.

Detailed Example:

Let’s say you’re sharpening a Stihl chain with a .325″ pitch. You would need a 5/32″ round file. Using a Stihl file guide, you’d set the angle to 30 degrees. For each cutter, you’d make 3-4 strokes with the file, ensuring consistent pressure and angle. After sharpening all the cutters, you’d use a flat file and a Stihl depth gauge tool to file the depth gauges. The tool will show you exactly how much material to remove. Finally, you’d round off the front of the depth gauges with the flat file.

Case Study: Improving Firewood Production Efficiency

I once consulted with a small firewood business that was struggling with low production rates. After analyzing their process, I identified that dull chainsaw chains were a major bottleneck. They were using cheap files and were not sharpening their chains frequently enough.

I recommended that they switch to Pferd files and implement a regular sharpening schedule. I also trained their employees on proper filing techniques. As a result, they saw a significant increase in their production rate, reducing the time it took to process a cord of firewood by 20%. This improvement translated into increased revenue and profitability.

Advanced Filing Techniques for Enhanced Sharpness and Longevity

Beyond the basic steps, there are several advanced techniques that can further enhance the sharpness and longevity of your chainsaw chain:

• Understanding Gullet Depth: The gullet is the area behind the cutting edge. Maintaining a proper gullet depth allows for efficient chip removal and prevents the chain from binding. Use a file guide that helps maintain the correct gullet depth.
• Consistent Filing Pressure: Applying consistent pressure is crucial for achieving a uniform cutting edge. Avoid pressing too hard, as this can damage the file and the chain.
• File Cleaning: Keep your files clean by using a file cleaning brush. This will remove metal filings and debris that can clog the file’s teeth and reduce its effectiveness.
• Rotating Files: Rotate your files regularly to ensure even wear. This will extend the life of the file and improve its cutting performance.
• Using a Chainsaw Sharpener: For high-volume sharpening, consider investing in a chainsaw sharpener. These machines can sharpen chains quickly and accurately, but they require careful setup and maintenance. I recommend models from Oregon or Tecomec for their reliability and precision.
• Adjusting the Filing Angle for Different Wood Types: For hardwoods like oak or maple, a slightly steeper filing angle (e.g., 35 degrees) can provide a more aggressive cut. For softwoods like pine or fir, a shallower angle (e.g., 25 degrees) can be more effective. This adjustment helps optimize the chain for the specific wood type being cut.

Strategic Insights:

• Chain Selection: Choosing the right chain for the job is crucial. Full chisel chains are ideal for clean wood and offer the fastest cutting speed. Semi-chisel chains are more durable and are better suited for dirty or abrasive wood.
• Bar Maintenance: Regularly clean and lubricate your chainsaw bar to reduce friction and wear. Check the bar rails for burrs and remove them with a flat file.
• Chain Tension: Maintain proper chain tension to prevent the chain from derailing or binding.
• Lubrication: Use a high-quality bar and chain oil to keep the chain lubricated. This will reduce friction and wear and extend the life of the chain. I prefer using a bio-degradable oil for environmental reasons.

Addressing Common Chainsaw Sharpening Problems

Even with the best tools and techniques, you may encounter some common problems when sharpening your chainsaw chain:

• Chain Cuts to One Side: This is usually caused by uneven sharpening. Ensure that all cutters are sharpened to the same angle and depth.
• Chain Binds or Chatters: This can be caused by dull cutters, high depth gauges, or a damaged bar. Sharpen the chain, file the depth gauges, and inspect the bar for damage.
• File Wears Out Quickly: This can be caused by using a low-quality file, applying too much pressure, or cutting abrasive wood. Use a high-quality file, apply consistent pressure, and avoid cutting dirty or abrasive wood.
• Difficulty Maintaining the Correct Angle: This is usually due to a lack of experience or using an inadequate file guide. Practice your filing technique and invest in a high-quality file guide.
