050 vs 063 Chain Gauge Explained (5 Expert Tips for Woodcutters)

One of the most overlooked aspects of chainsaw maintenance and performance is the chain gauge. Believe me, I’ve seen firsthand how mismatched gauges can lead to frustration, poor cutting, and even damage to your saw. But before we get into the nitty-gritty, let’s talk about why understanding chain gauges is crucial, especially if you’re looking to upgrade or eventually sell your chainsaw.

A well-maintained chainsaw with a properly matched chain is a hot commodity on the used market. Buyers are savvy; they know that a saw that’s been cared for properly will last longer and perform better. Investing the time to understand and maintain your chainsaw’s chain gauge can significantly increase its resale value. Think of it as adding a “performance package” that potential buyers will appreciate.

In this guide, I’ll break down the differences between 050 and 063 chain gauges, offer expert tips for woodcutters, and share some of my personal experiences to help you make informed decisions. I’ll also give you some insider knowledge that I have gathered over the years that you won’t find anywhere else!

What is Chain Gauge?

The chain gauge refers to the thickness of the drive links on your chainsaw chain. These drive links are the small metal pieces that fit into the guide bar groove. The gauge is measured in thousandths of an inch. So, a 050 gauge chain has drive links that are 0.050 inches thick, while a 063 gauge chain has drive links that are 0.063 inches thick.

Why Does Chain Gauge Matter?

The chain gauge must match the gauge of your chainsaw’s guide bar. Using the wrong gauge can lead to several problems:

Poor Cutting Performance: A chain that’s too loose will vibrate and cut unevenly.
Chain Damage: A chain that doesn’t fit properly is more likely to break or derail.
Guide Bar Damage: Using the wrong gauge can wear down the guide bar groove.
Safety Hazard: A loose or damaged chain is a safety risk.

I remember one time, years ago, I was helping a friend clear some fallen trees after a storm. He had recently purchased a new chain, thinking all chains were created equal. He installed a 063 gauge chain on a guide bar designed for a 050 gauge. The chain was loose, kept jumping off, and the cutting was incredibly slow and rough. Not only was it frustrating, but it was also dangerous. We quickly realized the mistake and switched to the correct chain, which immediately solved the problem. That experience taught me a valuable lesson about the importance of matching chain gauge to the guide bar.

Common Chain Gauges

While 050 and 063 are the most common, you’ll also find other gauges, such as:

043: Typically found on smaller, lighter-duty chainsaws.
058: Used on some mid-sized chainsaws.
080: Common on larger, professional-grade chainsaws.

050 Chain Gauge: A Detailed Look

The 050 chain gauge is a popular choice for a wide range of chainsaws, from homeowner models to some professional saws. It strikes a good balance between cutting speed and durability.

Advantages of 050 Chain Gauge

Faster Cutting Speed: Generally, a narrower gauge chain like 050 will cut slightly faster than a wider gauge because it removes less material.
Lower Power Requirement: Requires less power from the chainsaw, which can be beneficial for smaller saws.
Good for Smaller Wood: Works well for cutting smaller trees, branches, and firewood.

Disadvantages of 050 Chain Gauge

Less Durable: Not as robust as wider gauge chains, making it more susceptible to damage when cutting dirty or frozen wood.
More Prone to Stretching: May stretch more easily than wider gauge chains, requiring more frequent tension adjustments.
Not Ideal for Large Timber: May not be the best choice for felling large trees or cutting through thick logs.

Technical Specifications for 050 Chain Gauge

Here’s a breakdown of the technical aspects of 050 chain gauge:

Drive Link Thickness: 0.050 inches (1.27 mm)
Common Applications: Homeowner chainsaws, light-duty professional saws, limbing, pruning, firewood cutting.
Typical Chainsaw Sizes: 14-inch to 20-inch bars, depending on the saw’s power.
Recommended Wood Types: Softwoods (pine, fir, cedar) and hardwoods (maple, oak) up to medium diameter (12-18 inches).

Data Point: A study conducted by Oregon Tool (a leading chainsaw chain manufacturer) showed that 050 gauge chains experienced a 15% faster cutting speed compared to 063 gauge chains when cutting through pine logs of 12-inch diameter. However, the 063 gauge chains lasted 20% longer when cutting through oak logs of the same diameter.

063 Chain Gauge: A Deep Dive

The 063 chain gauge is a heavier-duty option, typically found on larger, more powerful chainsaws used for professional logging and felling.

Advantages of 063 Chain Gauge

Greater Durability: More resistant to damage from cutting dirty or frozen wood.
Less Prone to Stretching: Holds its tension better than narrower gauge chains, requiring less frequent adjustments.
Ideal for Large Timber: Well-suited for felling large trees and cutting through thick logs.
Improved Stability: The wider gauge provides better stability in the cut, reducing vibration and kickback.

Disadvantages of 063 Chain Gauge

Slower Cutting Speed: Generally cuts slower than narrower gauge chains because it removes more material.
Higher Power Requirement: Requires more power from the chainsaw, making it less suitable for smaller saws.
Heavier: The chain is heavier, which can increase fatigue during prolonged use.

Technical Specifications for 063 Chain Gauge

Let’s examine the technical specifications of 063 chain gauge:

Drive Link Thickness: 0.063 inches (1.6 mm)
Common Applications: Professional logging, felling large trees, cutting thick logs, heavy-duty firewood cutting.
Typical Chainsaw Sizes: 18-inch to 36-inch bars, depending on the saw’s power.
Recommended Wood Types: All wood types, especially hardwoods (oak, maple, hickory) and frozen wood.

Data Point: In my own experience, I’ve found that using a 063 gauge chain on a large oak log (over 24 inches in diameter) resulted in a smoother, more controlled cut compared to using a 050 gauge chain. The 063 gauge chain was less prone to vibration and kickback, making the cutting process safer and more efficient.

Expert Tip #1: Check Your Chainsaw’s Manual

Before you even think about buying a new chain, always consult your chainsaw’s manual. The manual will specify the correct chain gauge, pitch, and length for your saw. Using the wrong chain can void your warranty and potentially damage your chainsaw.

Practical Example

I had a neighbor who ignored his chainsaw manual and purchased a chain that was too long for his guide bar. He forced it on, and within minutes, the chain derailed, damaging the sprocket and the guide bar. He ended up spending more money to repair the damage than he would have if he had simply followed the manual’s recommendations.

Expert Tip #2: Understand Chain Pitch

While we’re on the topic of chain specifications, it’s important to understand chain pitch. The pitch is the distance between any three consecutive rivets on the chain, divided by two. Common pitches include 3/8 inch, .325 inch, and .404 inch.

How to Measure Chain Pitch

Measure the distance between any three consecutive rivets on the chain.
Divide that measurement by two.
The result is the chain pitch.

Example: If the distance between three rivets is 0.75 inches, the pitch is 0.75 / 2 = 0.375 inches, which is commonly referred to as a 3/8 inch pitch.

Importance of Matching Pitch

Just like chain gauge, the chain pitch must match the sprocket on your chainsaw. Using the wrong pitch can cause the chain to skip or bind, leading to poor cutting performance and potential damage to your saw.

Expert Tip #3: Consider the Type of Wood You’re Cutting

The type of wood you’re cutting should influence your choice of chain gauge. For softwoods like pine and fir, a 050 gauge chain is generally sufficient. However, for hardwoods like oak and maple, a 063 gauge chain may be a better choice due to its increased durability.

Data-Backed Recommendation

Softwoods (Pine, Fir, Cedar): 050 gauge chain
- Reasoning: Faster cutting speed, lower power requirement.
- Log Diameter Limit: Up to 18 inches.
Hardwoods (Oak, Maple, Hickory): 063 gauge chain
- Reasoning: Greater durability, less prone to stretching.
- Log Diameter Recommendation: 12 inches and above.
Frozen Wood: 063 gauge chain
- Reasoning: Increased resistance to damage.

Case Study: Firewood Preparation

I once worked on a project preparing firewood for a local community center. We were primarily cutting oak and hickory, which are notoriously hard on chainsaws. We initially used 050 gauge chains, but they kept dulling quickly and breaking. We switched to 063 gauge chains, and the difference was remarkable. The chains lasted much longer, and the cutting was more efficient. This experience solidified my belief in the importance of choosing the right chain gauge for the job.

Expert Tip #4: Sharpen Your Chains Regularly

A sharp chain is essential for safe and efficient cutting, regardless of the chain gauge. A dull chain requires more force to cut, which can increase the risk of kickback and fatigue.

How to Sharpen Your Chainsaw Chain

Secure the Chainsaw: Place the chainsaw in a vise or on a stable surface.
Use a Chainsaw File: Use a round chainsaw file that matches the size of the cutting teeth.
Maintain the Correct Angle: File each tooth at the correct angle, as specified by the chain manufacturer.
File Each Tooth Evenly: File each tooth the same number of strokes to ensure consistent cutting performance.
Check the Depth Gauges: Use a depth gauge tool to ensure the depth gauges are set correctly.

Technical Detail: The correct filing angle for most chainsaw chains is between 25 and 35 degrees. The depth gauges should be set approximately 0.025 inches below the cutting teeth.

My Personal Sharpening Routine

I typically sharpen my chainsaw chain after every two to three tanks of fuel. This ensures that the chain is always sharp and ready to cut. I also use a chainsaw file guide to help me maintain the correct filing angle and depth gauge settings. This tool has significantly improved the consistency and quality of my sharpening.

Expert Tip #5: Maintain Proper Chain Tension

Proper chain tension is crucial for safe and efficient cutting. A chain that’s too loose can derail, while a chain that’s too tight can bind and overheat.

How to Check Chain Tension

Wear Gloves: Always wear gloves when handling a chainsaw chain.
Pull the Chain Away from the Guide Bar: Pull the chain away from the guide bar at the midpoint.
Check the Gap: The gap between the chain and the guide bar should be approximately 1/8 inch.
Adjust Tension as Needed: Use the chain tensioning mechanism to adjust the tension as needed.

Important Note: Always check chain tension when the chain is cold. The chain will expand as it heats up during use.

Signs of Improper Chain Tension

Chain Derailment: A chain that frequently derails is likely too loose.
Excessive Vibration: Excessive vibration can indicate that the chain is too loose or too tight.
Overheating: A chain that overheats is likely too tight.
Slow Cutting: Slow cutting can be a sign of a dull chain or improper chain tension.

Chain Oil and Lubrication: The Unsung Hero

I’ve seen many woodcutters neglect the importance of proper chain lubrication. Using the correct chain oil is just as crucial as choosing the right chain gauge and keeping your chain sharp.

Why Chain Oil Matters

Reduces Friction: Chain oil reduces friction between the chain and the guide bar, preventing overheating and wear.
Extends Chain Life: Proper lubrication extends the life of the chain and the guide bar.
Improves Cutting Performance: A well-lubricated chain cuts more smoothly and efficiently.

Types of Chain Oil

Petroleum-Based Chain Oil: The most common type of chain oil.
Vegetable-Based Chain Oil: An environmentally friendly alternative to petroleum-based chain oil.
Synthetic Chain Oil: Offers superior lubrication and performance in extreme conditions.

My Chain Oil Preference

I prefer to use vegetable-based chain oil whenever possible because it’s biodegradable and less harmful to the environment. However, for heavy-duty cutting in extreme conditions, I sometimes use synthetic chain oil for its superior lubrication properties.

Data Point: A study by the US Forest Service found that using vegetable-based chain oil reduced the environmental impact of logging operations by up to 50% compared to using petroleum-based chain oil.

Beyond the Basics: Advanced Considerations

For those of you who want to take your chainsaw knowledge to the next level, here are some advanced considerations:

Chisel vs. Semi-Chisel Chains

Chisel Chains: Have square-cornered teeth that cut aggressively and quickly. Best suited for clean wood and experienced users.
Semi-Chisel Chains: Have rounded-corner teeth that are more forgiving and durable. Better suited for dirty or frozen wood and less experienced users.

Full-Skip vs. Standard Chains

Full-Skip Chains: Have fewer cutting teeth, which reduces the power requirement and allows for faster cutting in large timber.
Standard Chains: Have more cutting teeth, which provides smoother cutting and better control.

Low-Kickback Chains

Designed with features to reduce the risk of kickback, such as bumper links or guard links. Recommended for beginners and those who prioritize safety.

Chain Identification and Markings

Understanding the markings on your chainsaw chain can help you identify its specifications and ensure you’re using the correct chain for your saw.

Common Markings:

Chain Gauge: Often stamped on the drive links.
Chain Pitch: May be indicated by a number or symbol.
Manufacturer: The manufacturer’s logo is usually present.
Type of Chain: Chisel, semi-chisel, low-kickback, etc.

Troubleshooting Common Chainsaw Problems

Even with the right chain gauge and proper maintenance, you may still encounter problems with your chainsaw. Here are some common issues and their solutions:

Chain Won’t Cut: Dull chain, improper chain tension, wrong chain gauge, or clogged air filter.
Chain Keeps Derailling: Chain too loose, worn sprocket, damaged guide bar, or wrong chain gauge.
Chainsaw Overheats: Chain too tight, insufficient chain oil, clogged air filter, or worn piston rings.
Excessive Vibration: Chain too loose, unbalanced chain, worn sprocket, or damaged guide bar.

Safety First: Essential Safety Gear for Woodcutters

No discussion of chainsaws would be complete without emphasizing the importance of safety. Chainsaws are powerful tools that can cause serious injury if not used properly.

Essential Safety Gear

Chainsaw Helmet: Protects your head from falling debris and kickback.
Eye Protection: Safety glasses or a face shield to protect your eyes from flying chips.
Hearing Protection: Earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
Chainsaw Gloves: Provide grip and protection for your hands.
Chainsaw Chaps: Protect your legs from accidental cuts.
Steel-Toed Boots: Protect your feet from falling logs and accidental cuts.
