I confidently estimated the chainsaw blade length I needed based on a quick visual assessment. Turns out, I was way off. I ended up having to make multiple passes, which not only wasted time and fuel but also left a less-than-ideal cut surface.
That’s why I’m writing this for you. Measuring your chainsaw blade isn’t just about knowing the number; it’s about ensuring safety, efficiency, and quality in all your wood processing endeavors. In this article, I’ll share my top 5 pro tips for accurately measuring your chainsaw blade length, along with a deep dive into related aspects of wood processing, logging tools, and firewood preparation. Let’s get to it, so you don’t end up in a similar situation!
How to Measure Chainsaw Blade Length (5 Pro Tips for Precision)
Getting the chainsaw blade length right is fundamental, like knowing your knots in climbing or understanding grain direction when splitting wood. It affects everything from the size of logs you can safely cut to the overall performance and longevity of your saw.
1. Understanding the Correct Terminology: Bar Length vs. Cutting Length
First, let’s clear up some common confusion. The term “chainsaw blade length” is often used, but what we’re actually measuring is the guide bar length. This is the metal bar that the chain runs around. The cutting length, or effective cutting length, is slightly shorter than the guide bar length. It’s the actual length of the bar that’s available for cutting the wood.
- Guide Bar Length: The full length of the guide bar, measured from the tip to where it sits flush with the chainsaw body.
- Cutting Length: The portion of the guide bar that the chain uses to cut the wood. Typically, it’s a couple of inches shorter than the guide bar length.
Using the correct terminology will help you avoid misunderstandings when buying replacement bars or chains. For example, if you’re talking to a supplier and say “I need a 20-inch blade,” they’ll assume you mean a 20-inch guide bar.
2. The Foolproof Measurement Technique: Tip to Mounting Point
The most accurate way to measure your chainsaw bar is to use a measuring tape and measure from the tip of the bar to the point where the bar sits flush against the chainsaw body.
Here’s a step-by-step guide:
- Safety First: Always remove the spark plug wire before working on your chainsaw. This prevents accidental starts. Wear gloves for added protection.
- Clean the Bar: Wipe down the guide bar to remove any dirt, sawdust, or oil. This will give you a clear view and a more accurate measurement.
- Locate the Mounting Point: This is where the guide bar meets the chainsaw body. It’s usually a raised area or a flange.
- Measure Carefully: Extend your measuring tape from the tip of the bar to the mounting point. Make sure the tape is straight and taut.
- Record the Measurement: Note the measurement in inches or centimeters. This is your guide bar length.
Pro Tip: Use a metal measuring tape for the most accurate results. Cloth tapes can stretch and give you an incorrect reading.
3. Reading the Bar: Deciphering the Numbers
Many chainsaw bars have the length stamped directly onto them. This is usually located near the base of the bar, close to the mounting point. The length might be expressed in inches or centimeters.
Example: You might see “20” or “50cm” stamped on the bar. This indicates a 20-inch or 50-centimeter guide bar length.
However, there are a few caveats:
- Wear and Tear: Over time, the stamped numbers can wear off, making them difficult to read.
- Paint or Dirt: The numbers might be obscured by paint, dirt, or rust. Clean the bar thoroughly before trying to read the numbers.
- Inaccurate Markings: In rare cases, the stamped numbers might be incorrect, especially on older or aftermarket bars. Always double-check with a manual measurement.
4. Chainsaw Model Information: Cross-Referencing with the Manual
Your chainsaw’s owner’s manual is a treasure trove of information, including the recommended guide bar lengths for your specific model. The manual will typically list a range of compatible bar lengths.
Why is this important?
- Optimal Performance: Using the recommended bar length ensures that your chainsaw operates at its optimal performance level.
- Safety: Using a bar that’s too long or too short can create safety hazards, such as increased kickback or reduced control.
- Warranty: Using a non-recommended bar length might void your chainsaw’s warranty.
How to find the information:
- Locate Your Manual: If you don’t have the physical manual, you can usually find a digital copy on the manufacturer’s website.
- Identify Your Model: The model number is usually printed on a sticker or plate on the chainsaw body.
- Find the Specifications: Look for the section that lists the technical specifications, including the recommended guide bar lengths.
Personal Story: I once tried to use a longer bar than recommended on my old Stihl. I thought it would let me tackle bigger logs faster. Big mistake! The chainsaw was underpowered, the chain kept binding, and it was generally a frustrating and dangerous experience. I learned my lesson: stick to the manufacturer’s recommendations.
5. Considering the Wood Type and Project Size: Matching Bar Length to the Task
The ideal chainsaw bar length depends on the type of wood you’re cutting and the size of your projects.
Here’s a general guideline:
- Small Projects (Firewood, Pruning): A shorter bar (14-16 inches) is usually sufficient. It’s lighter, more maneuverable, and easier to control.
- Medium Projects (Felling Small Trees, Bucking Logs): A medium-length bar (18-20 inches) is a good all-around choice. It provides a balance of power and maneuverability.
- Large Projects (Felling Large Trees, Milling Lumber): A longer bar (20+ inches) is necessary to handle the bigger cuts. However, it requires more power and experience to operate safely.
Wood Type Considerations:
- Softwoods (Pine, Fir, Spruce): Softwoods are easier to cut, so you can often get away with a shorter bar.
- Hardwoods (Oak, Maple, Ash): Hardwoods require more power and a longer bar to cut efficiently.
Important Note: Never use a chainsaw bar that’s longer than your chainsaw is designed to handle. This can damage the engine and create a serious safety hazard.
Data Point: According to a study by the US Forest Service, chainsaw accidents are more common when operators use improperly sized or maintained equipment. Choosing the right bar length is a crucial aspect of safe chainsaw operation.
Beyond the Blade: Optimizing Your Wood Processing Workflow
Measuring your chainsaw blade is just the first step. To truly optimize your wood processing workflow, you need to consider a range of factors, from log handling to drying methods.
Log Handling Efficiency: From Forest to Firewood Pile
Efficient log handling is crucial for minimizing time and effort. Here’s what I’ve learned over the years:
- Strategic Log Placement: Plan your cuts and position the logs so that you can make multiple cuts without having to reposition them. Use log jacks or cant hooks to lift and rotate heavy logs.
- Ergonomic Workstation: Set up a comfortable and ergonomic workstation to reduce strain and fatigue. This might include a sturdy sawbuck, a log splitter stand, and a well-organized tool area.
- Mechanical Assistance: Consider using mechanical aids such as log loaders, skidders, or firewood processors to handle large volumes of wood.
Case Study: A small firewood producer in Vermont implemented a new log handling system that included a log loader and a firewood processor. This reduced their processing time by 40% and increased their production volume by 50%.
Material Sourcing Strategies: Selecting Sustainable Timber
Sustainable timber sourcing is not only environmentally responsible, but it can also be economically beneficial.
- Local Sourcing: Prioritize sourcing timber from local suppliers or landowners. This reduces transportation costs and supports local economies.
- Salvaged Wood: Consider using salvaged wood from storm-damaged trees, construction sites, or demolition projects. This is a great way to reduce waste and save money.
- Certified Sustainable Timber: Look for timber that’s certified by organizations such as the Forest Stewardship Council (FSC). This ensures that the timber is harvested in a sustainable and responsible manner.
Expert Quote: “Sustainable forestry is not just about protecting the environment; it’s about ensuring the long-term viability of the wood products industry,” says Dr. Emily Carter, a forestry expert at the University of Maine.
