Lightweight Chainsaw Bars Review (Tsumura’s Ultra-Durable Design)

Durability. That’s the word that always comes to mind when I think about a chainsaw bar. It’s the backbone of your saw, the part that guides the chain through countless cuts, enduring immense friction and pressure. And in my years of experience felling trees, bucking logs, and processing firewood, I’ve learned that not all chainsaw bars are created equal. Some buckle under pressure, others wear out quickly, and some… well, some are built to last. Today, I want to share my thoughts on one of those exceptional bars: the Tsumura Ultra-Durable Lightweight Chainsaw Bar.

The Quest for the Perfect Chainsaw Bar

As a seasoned logger and avid woodworker, I’ve seen my fair share of chainsaw bars come and go. I’ve worked with a variety of wood species, from the softest pine to the densest hardwoods, and in conditions ranging from scorching summer heat to freezing winter temperatures. This experience has taught me that the chainsaw bar is just as crucial as the saw itself. A weak or poorly designed bar can lead to inefficient cutting, increased wear on the saw, and even dangerous kickback situations.

Why Lightweight Matters

You might be wondering, “Why all the fuss about lightweight?” Well, picture yourself spending hours in the woods, felling trees or bucking logs. The weight of your chainsaw becomes a significant factor. A heavier saw, especially with a heavy bar, can lead to fatigue, reduced control, and an increased risk of injury. A lightweight bar, like the Tsumura Ultra-Durable, can make a world of difference in terms of maneuverability and endurance.

My Own Close Call

I remember one particularly grueling day in the Oregon woods. I was working with a large Douglas fir, and my saw, equipped with a standard bar, felt incredibly heavy. As the day wore on, fatigue set in. During one cut, I lost my grip momentarily, and the saw kicked back. Fortunately, I had proper safety gear and quick reflexes, but it was a close call. That incident reinforced the importance of using lightweight equipment to minimize fatigue and maintain control.

Wood Species and Processing Techniques

The type of wood you’re cutting and the processing techniques you use can have a significant impact on the performance and lifespan of your chainsaw bar.

Understanding Wood Density

Wood density is a measure of the mass of wood per unit volume. Denser woods, like oak and maple, require more power to cut than softer woods, like pine and cedar. When cutting dense woods, it’s important to use a sharp chain and a bar that is designed to withstand the increased stress.

Density of Common Wood Species (approximate):

Balsa: 80-160 kg/m³
Pine: 350-550 kg/m³
Cedar: 350-580 kg/m³
Oak: 600-900 kg/m³
Maple: 630-750 kg/m³
Ironwood: 1000+ kg/m³

Processing Techniques

Felling: The process of cutting down a tree. Requires careful planning and execution to ensure safety.
Bucking: The process of cutting a felled tree into smaller logs.
Splitting: The process of splitting logs into firewood.
Milling: The process of sawing logs into lumber.

Each of these techniques places different demands on the chainsaw bar. Felling requires precision and control, while bucking and milling require power and endurance.

My Firewood Processing Ritual

I’ve developed a pretty efficient system for processing firewood over the years. It starts with felling trees in the late winter, after the sap has stopped flowing. I let the logs dry out for several months before bucking them into firewood lengths. Then, I use a hydraulic splitter to split the logs into manageable pieces. Finally, I stack the firewood in a well-ventilated area to season for at least a year before burning it.

Tool Selection and Maintenance

Choosing the right tools and maintaining them properly is essential for safe and efficient wood processing.

Chainsaw Selection

The size and power of your chainsaw should be appropriate for the type of work you’re doing. For small jobs, like pruning and limbing, a small, lightweight saw is sufficient. For larger jobs, like felling trees and bucking logs, you’ll need a more powerful saw.
