Dotmalls Sawsharpener Review (Pro Tips for Efficient Chain Sharpening)

Alright, let’s dive into the fascinating world of chainsaw maintenance and explore the Dotmalls saw sharpener.

Introduction: A Sharp Chain, A Sharp Mind

In the realm of wood processing, logging, and firewood preparation, the chainsaw reigns supreme. But let’s face it – a dull chain is the bane of any woodworker’s existence. It’s like trying to spread butter with a spoon; frustrating, inefficient, and downright dangerous. You end up expending more energy, producing subpar results, and potentially damaging your equipment.

I’ve spent years in the field, felling trees, bucking logs, and splitting firewood. I’ve seen firsthand the difference a sharp chain makes. A sharp chain bites into the wood with ease, allowing you to make clean, precise cuts with minimal effort. A dull chain, on the other hand, chatters, bounces, and requires excessive force, leading to fatigue and increased risk of kickback.

That’s where the Dotmalls saw sharpener comes in. I first encountered this tool a few years back when a fellow logger, old “Timber Tim” as we called him, swore by it. Tim was a grizzled veteran who could drop a tree exactly where he wanted it, every time. He attributed much of his success to maintaining a razor-sharp chain, and the Dotmalls sharpener was his secret weapon.

Now, I’m not one to blindly follow trends or accept anecdotal evidence. I needed to put this thing to the test myself. So, I bought one, used it extensively, and compared it to other sharpening methods I’ve used over the years.

The Importance of a Sharp Chain: More Than Just Efficiency

Let’s start with the basics: why is chain sharpness so crucial? It’s not just about cutting faster; it’s about safety, efficiency, and the longevity of your chainsaw.

• Safety: A sharp chain bites into the wood cleanly, reducing the risk of kickback. Kickback is a sudden, violent upward or backward movement of the chainsaw that can cause serious injury. A dull chain is more likely to grab, bind, and kick back. According to the Consumer Product Safety Commission (CPSC), chainsaw-related injuries send tens of thousands of people to the emergency room each year, and many of these injuries are caused by kickback.
• Efficiency: A sharp chain cuts faster and more efficiently, allowing you to get more work done in less time. This translates to increased productivity and reduced fatigue. In a study conducted by the U.S. Forest Service, loggers using sharp chains were able to cut up to 20% more timber per day compared to those using dull chains.
• Chainsaw Longevity: A sharp chain puts less stress on the chainsaw engine, extending its lifespan. A dull chain requires the engine to work harder, which can lead to overheating, premature wear, and costly repairs.
• Cut Quality: A sharp chain produces cleaner, more precise cuts. This is especially important for woodworking projects where accuracy is essential. A dull chain tears and splinters the wood, resulting in a rough, uneven surface.
• Fuel Efficiency: A sharp chain requires less power to operate, resulting in improved fuel efficiency. This can save you money on fuel costs over time. A study by the Swedish University of Agricultural Sciences found that chainsaws with sharp chains consumed up to 15% less fuel compared to those with dull chains.

The Dotmalls Saw Sharpener: An In-Depth Look

Now, let’s get to the heart of the matter: the Dotmalls saw sharpener. This tool is designed to make chain sharpening easier, faster, and more precise. It’s a manual sharpener that uses a file to sharpen each cutter on the chain.

• Design and Construction: The Dotmalls sharpener is typically made of durable materials like aluminum or steel. It consists of a frame that holds the file at a precise angle and depth. The frame is designed to be clamped onto the chainsaw bar, providing a stable platform for sharpening.
• Features:
  • Adjustable Angle: The Dotmalls sharpener allows you to adjust the sharpening angle to match the specific chain you’re using. This is crucial for achieving optimal cutting performance.
  • Depth Control: The sharpener also features a depth control mechanism that ensures each cutter is sharpened to the same depth. This is essential for maintaining a balanced chain.
  • File Guide: The file guide helps you maintain a consistent angle and depth while sharpening, resulting in a more uniform and accurate sharpening job.
  • Easy to Use: The Dotmalls sharpener is designed to be user-friendly, even for beginners. It’s relatively easy to set up and use, and it comes with clear instructions.
• How it Works: The Dotmalls sharpener works by guiding a file along the cutting edge of each cutter on the chain. The sharpener is clamped onto the chainsaw bar, and the file is inserted into the file guide. The user then moves the file back and forth along the cutter, removing metal and creating a sharp edge.

My Hands-On Experience: A Step-by-Step Guide

Alright, let’s get down to the practical stuff. Here’s my experience using the Dotmalls saw sharpener, step by step:

1. Safety First: Before you start, make sure the chainsaw is turned off and the chain brake is engaged. Wear safety glasses and gloves to protect your eyes and hands. I cannot stress this enough; safety should always be your top priority.
2. Prepare the Chainsaw: Clean the chainsaw chain and bar with a brush to remove any dirt, sawdust, or debris. This will help the sharpener work more effectively.
3. Clamp the Sharpener: Clamp the Dotmalls sharpener onto the chainsaw bar, ensuring it’s securely attached. Make sure the sharpener is positioned correctly so that the file will contact the cutting edge of the cutter.
4. Adjust the Angle and Depth: Adjust the sharpening angle and depth to match the specifications of your chainsaw chain. Refer to your chainsaw’s owner’s manual for the correct settings. This is a critical step; using the wrong angle or depth can damage the chain.
5. Sharpen the Cutters: Insert the file into the file guide and begin sharpening each cutter. Use smooth, even strokes, applying moderate pressure. Count the number of strokes you use on each cutter to ensure consistency. I usually aim for 3-5 strokes per cutter.
6. Check Your Work: After sharpening a few cutters, check your work to ensure the cutters are being sharpened evenly and to the correct angle and depth. Use a magnifying glass to inspect the cutting edges for sharpness and uniformity.
7. Repeat: Repeat the sharpening process for all the cutters on the chain. Be sure to sharpen each cutter on the same side of the chain before moving to the other side.
8. Lower the Rakers (Optional): After sharpening the cutters, you may need to lower the rakers (also known as depth gauges) to maintain optimal cutting performance. The rakers control the depth of cut, and they need to be adjusted as the cutters wear down. Use a raker filing tool to lower the rakers to the correct height. Again, refer to your chainsaw’s owner’s manual for the correct settings.
9. Test the Chain: After sharpening the chain, test it on a piece of wood to ensure it’s cutting properly. The chain should bite into the wood easily and produce clean, even chips. If the chain is still dull or cutting unevenly, repeat the sharpening process.
10. Clean and Lubricate: After sharpening, clean the chainsaw chain and bar and lubricate the chain with chainsaw oil. This will help protect the chain from rust and corrosion and ensure smooth operation.
