Choosing the Right Grinder & Accessories

The type of grinder you use greatly affects the final result. Let’s look at the options.

Angle Grinder or Dedicated Chainsaw Grinder?

An angle grinder chainsaw sharpener can be a cost-effective choice if you already own an angle grinder. However, dedicated chainsaw sharpening grinders are specifically designed for the task and offer greater precision and control. They ensure consistent angles and depth, which is vital for optimal cutting performance.

• Angle Grinder:
  • Pros: More affordable if you already own one. Versatile for other tasks.
  • Cons: Steeper learning curve. Harder to maintain consistent angles. Requires an angle grinder chainsaw sharpener attachment.
• Dedicated Chainsaw Grinder:
  • Pros: Easier to use. More precise and consistent results. Designed specifically for chainsaw chains.
  • Cons: More expensive upfront. Less versatile than an angle grinder.

Selecting the Correct Grinding Wheel

The grinding wheel for chainsaw sharpening is crucial. Use a wheel specifically designed for sharpening chainsaw chains. These wheels are typically made of aluminum oxide and come in various sizes and grits.

Wheel Type	Grit	Use
Aluminum Oxide	Medium	General sharpening
Pink Aluminum Oxide	Fine	Finishing and precision sharpening
CBN (Cubic Boron Nitride)	Very Fine	Long-lasting, ideal for frequent sharpening

Essential Safety Gear

Safety should always be your top priority. Wear the following protective gear:

• Safety glasses or a face shield: To protect your eyes from flying debris.
• Gloves: To protect your hands from sharp edges and heat.
• Hearing protection: Grinders can be very loud.
• Dust mask: To avoid inhaling metal dust.

Preparing Your Chainsaw Chain

Before you start grinding, take the time to properly prepare your chainsaw chain.

Cleaning the Chain

A clean chain is easier to sharpen. Remove any dirt, oil, or debris with a wire brush and solvent. This will also help extend the life of your grinding wheel for chainsaw.

Inspecting the Chain

Check the chain for any damage, such as broken or severely worn teeth. Replace the chain if necessary. Also, look for loose rivets or damaged tie straps.

Marking the Starting Tooth

Use a marker to indicate the first tooth you sharpen. This will help you keep track of your progress and ensure you sharpen each tooth.

Chainsaw Grinder Sharpening Techniques

Now, let’s get into the actual sharpening process.

Setting Up Your Grinder

1. Secure the grinder: Mount your chainsaw sharpening grinder on a stable surface. If using an angle grinder chainsaw sharpener attachment, ensure it is securely attached to the grinder.
2. Adjust the angle: Set the grinding angle according to the manufacturer’s specifications for your chain. This is typically around 25-35 degrees for the top plate and 5-10 degrees for the side plate.
3. Adjust the depth: Set the depth stop to control how much material you remove from each tooth. Start with a shallow setting and gradually increase it as needed.

Sharpening Each Tooth

1. Position the chain: Place the chain in the grinder vise, aligning the first tooth with the grinding wheel.
2. Grind the top plate: Gently lower the grinding wheel onto the top plate of the tooth. Use light, consistent pressure and avoid overheating the metal. Sharpen each tooth with same amount of stroke.
3. Grind the side plate: Rotate the chain and align the side plate with the grinding wheel. Again, use light, consistent pressure to sharpen the side plate.
4. Repeat: Repeat the process for each tooth, moving systematically around the chain. Use consistent movements and pressure to ensure uniform sharpening.

Maintaining Consistency

Consistency is key to achieving a well-sharpened chain. Here are some tips to help you maintain consistency:

• Count your strokes: Use the same number of strokes for each tooth.
• Maintain consistent pressure: Avoid applying too much pressure, which can overheat the metal and damage the tooth.
• Check your angles: Regularly check the grinding angles to ensure they are correct.

Filing Chainsaw With Grinder

While the grinder does the bulk of the work, you can use a file to fine-tune the cutting edges. This is especially helpful for removing any burrs or imperfections left by the grinder. Filing chainsaw with grinder will create a razor-sharp edge.

Adjusting the Depth Gauges (Rakers)

The depth gauges, also known as rakers, control how much the chain bites into the wood. After sharpening, you may need to adjust the depth gauges to maintain optimal cutting performance.

Determining the Correct Depth Gauge Setting

The correct depth gauge setting depends on the type of wood you are cutting. Softer woods require a deeper setting, while harder woods require a shallower setting. Consult your chainsaw manual for the recommended depth gauge setting.

Lowering the Depth Gauges

Use a depth gauge tool and a flat file to lower the depth gauges. Place the tool on top of the depth gauge and file away any excess material that protrudes above the tool. File each depth gauge evenly to maintain balance.

Common Mistakes to Avoid

• Over-grinding: Removing too much material from the teeth.
• Incorrect angles: Sharpening the teeth at the wrong angles.
• Uneven sharpening: Sharpening some teeth more than others.
• Neglecting the depth gauges: Failing to adjust the depth gauges after sharpening.
• Using a dull grinding wheel: A dull wheel will generate more heat and produce a poor-quality edge.

Maintaining Your Chainsaw Sharpening Grinder

Proper maintenance will help extend the life of your chainsaw sharpening grinder and ensure it continues to perform optimally.

Cleaning the Grinder

Regularly clean your grinder to remove metal dust and debris. Use a brush or compressed air to clean the grinding wheel, vise, and other components.

Replacing the Grinding Wheel

Replace the grinding wheel for chainsaw sharpening when it becomes worn or damaged. A worn wheel will produce a poor-quality edge and can be dangerous to use.

Lubricating Moving Parts

Lubricate the moving parts of your grinder to keep them operating smoothly. Use a light oil or grease specifically designed for power tools.

When to Replace Your Chainsaw Chain

Even with regular sharpening, chainsaw chains eventually wear out and need to be replaced. Here are some signs that it’s time for a new chain:

• Broken or severely worn teeth
• Loose rivets or tie straps
• Excessive stretching of the chain
• Difficulty maintaining a sharp edge

Choosing the Best Chainsaw Grinder

The best chainsaw grinder for you will depend on your needs and budget. Consider the following factors when choosing a grinder:

• Ease of use: Look for a grinder that is easy to set up and operate.
• Precision: Choose a grinder that offers precise angle and depth adjustments.
• Durability: Select a grinder that is built to last.
• Price: Compare prices from different brands and retailers to find the best deal.

Top Chainsaw Grinder Recommendations

It’s difficult to point at a single option as best chainsaw grinder, as the requirements vary from user to user. Research is key. However, a few brands consistently receive positive reviews:

• Oregon
• Timberline
• Farmertec

Troubleshooting Common Problems

• Chain won’t cut straight: This could be due to unevenly sharpened teeth or incorrect depth gauge settings.
• Chain is smoking: This could be due to overheating the metal. Use lighter pressure and allow the chain to cool down between passes.
• Chain is vibrating excessively: This could be due to a loose chain or damaged components.

Advantages of Grinding vs. Filing

While filing chainsaw with grinder is useful for touch-ups, using a grinder offers several advantages for sharpening:

Feature	Grinder	File
Speed	Much faster	Slower
Precision	More precise angles and depth	More difficult to maintain consistency
Consistency	Easier to achieve consistent results	Requires more skill and experience
Effort	Less physically demanding	More physically demanding

Fathoming Different Chain Types

Different chain types require slightly different sharpening approaches. Low-profile chains, for example, often need shallower depth gauge settings than standard chains. Always consult your chainsaw and chain manuals for specific recommendations.
