As an avid chainsaw user, I know firsthand the importance of selecting the right chainsaw bar for the job. The bar is a critical component that can make or break your cutting experience. In this comprehensive guide, I’ll walk you through the key factors to consider when choosing a chainsaw bar and provide an overview of the different types available.
What’s the Importance of Chainsaw Bar Type Selection?
Choosing the right bar type for your chainsaw is crucial for performance, safety, and efficiency. The bar needs to be matched to the power and size of your saw’s engine. It also needs to accommodate the length and type of chain you’ll be using. If the bar is too short, you’ll be limited in your cutting capacity and experience more binding. If it’s too long, there won’t be enough power to efficiently cut through wood.
The material a bar is constructed from also affects durability and resistance to wear and kickback. Bars with certain safety features can further reduce kickback and vibration for more control. Taking the time to select the optimal bar will provide the best cutting experience and minimize fatigue, strain, and safety risks.
Factors Affecting Chainsaw Bar Selection
Several key factors should be considered when selecting a replacement or new chainsaw bar:
Chainsaw power and engine size
The engine displacement and power output of your chainsaw determines how long a bar it can efficiently operate. Smaller electric or gas chainsaws under 40cc are best suited for shorter bars from 10-16 inches. Medium-sized saws from 40-50cc can utilize longer 16-20 inch bars. Professional-grade saws 70cc and up have the most power for 20-36 inch bars. Always match the bar length to the manufacturer’s recommendations.
Type of work and cutting requirements
Think about your most frequent cutting tasks. For light pruning and small trees, a shorter compact bar from 12-16 inches provides the best control. Longer bars from 18-24 inches are ideal for felling medium-sized trees and large branches. The longest bars over 24 inches enable professional tree removal and milling of wide logs. Choose the minimum bar length to handle your cutting needs.
Safety and kickback reduction
Look for bars with built-in safety features like hand guards, anti-kickback bumpers, and chain catches that reduce risky kickbacks. Low kickback bars with guide ramps also make plunge cuts into wood safer. Consider safety over longer reach if you’re an occasional user.
Weight and maneuverability
The heavier a chainsaw bar, the more fatiguing it can be to operate, especially overhead. Solid bars are heavier than laminated ones. Compact lighter bars are ideal for use on poles or pruning. Make sure to pick a bar weight suitable for your strength and chainsaw size.
Types of Chainsaw Bars
There are a few main types of chainsaw bars, each with their own benefits:
These single-piece bars provide the most rigid support for the chain. They’re extremely durable, resistant to bending, and don’t require frequent truing. However, solid bars are heavier and can cause more vibration. They’re best for professional use.
Laminated bars with nose wheels
Built up from several bonded metal layers, these bars are lightweight while still sturdy. The composite construction absorbs more vibration. The nose wheel at the tip further reduces kickback risks. Laminated bars need more frequent truing as they gradually wear.
Solid bars with replacement tips
The bulk of these bars are solid with an indexable replaceable tip section near the nose. When the section wears down, you can replace just the tip rather than the entire bar. The solid construction offers rigidity while the replaceable tip adds convenience.
Chainsaw Bar Length: Pros and Cons
The length of your chainsaw bar involves key tradeoffs. Let’s look at the advantages and disadvantages of both longer and shorter bar lengths.
Advantages of Longer Bars
- Less bending over or crouching to cut elevated branches or the bottoms of tall trunks. A longer bar provides greater reach from a standing position.
- Extended reach enables cutting wider logs or felling larger trees in a single pass. Less repositioning needed.
- The additional bar length improves leverage and allows faster and more efficient cutting. Less binding in the kerf.
Disadvantages of Longer Bars
- Substantially heavier and more fatiguing to use, especially overhead. Can be challenging to control.
- Require more engine power to drive longer chains. Not suitable for smaller electric or gas chainsaws.
- Increased kickback potential due to greater leverage. Can be more difficult for amateurs to safely control.
Advantages of Shorter Bars
- Lightweight and highly maneuverable for effortless control. Easier to operate and less tiring.
- Better matched to the power of smaller chainsaw engines. Maximizes cutting performance.
- Compact size allows easy handling in confined spaces and optimal balance.
Disadvantages of Shorter Bars
- Require more bending, stooping, and repositioning when cutting taller trunks or high branches.
- Limited reach. May not be able to cut completely through larger diameter logs in one pass.
- Reduced leverage decreases cutting speed and increases binding in the kerf. Can be slower and less efficient.
Chainsaw Chain Types and Compatibility
In addition to the bar, choosing the right chainsaw chain is also essential. The chain must be precisely matched to the bar’s gauge and length.
Measuring Chainsaw Chains
Chainsaw chains are classified by key measurements:
- Pitch – The distance between consecutive rivet holes (e.g. 3/8 inch). Affects how coarse or fine the chain cuts.
- Gauge – The drive link width (e.g. 0.050 inch). Must match the bar groove width.
- Number of drive links – The matching chain will have the same number of links as the bar’s length in inches.
Matching Chainsaw Bar and Chain
To achieve optimal cutting performance, it’s critical to pair the bar with the correctly sized chain:
- The chain pitch and gauge must precisely fit the bar’s groove dimensions.
- The chain length must match the bar length for smooth running.
- Account for the chainsaw’s power when choosing the chain type and gauge – thicker chains require more power.
An improper chain/bar mismatch can result in accelerated wear, jamming, or thrown chains. Always consult the manufacturer’s chain compatibility charts.
Chainsaw Bar Maintenance and Safety
To keep your chainsaw operating safely and efficiently, proper bar maintenance is essential. Here are some key tips:
Chainsaw Bar Tension and Maintenance
- Maintaining proper chain tension reduces vibration and prevents derailing. Tensioning varies between saws, so consult your owner’s manual.
- Frequently lubricate the bar groove and chain with quality bar and chain oil for reduced friction and wear. Oil before each use.
- Monitor bars for burring and uneven wear. Use a file to remove burrs. Replace a bar once the groove is worn.
- Periodically true and dress bars to restore straightness and smooth running. Address issues before they accelerate wear.
Chainsaw Bar Safety Features
Many modern bars now include helpful safety enhancements:
- Tip guards and bar nose wheels limit the risk of dangerous kickbacks when plunge cutting.
- Built-in hand guards create a barrier between your hand and the chain if slippage occurs.
- Chain catches retain a derailed chain to prevent injury. Look for catcher pins near the saw body.
- Low-kickback guide ramps and groove angles reduce the chance of violent kickback when initially contacting wood.
Choosing the Right Chainsaw Bar for Your Needs
Selecting the ideal chainsaw bar involves balancing your cutting requirements, chainsaw model, safety priorities, and budget. Follow this process:
Assessing Your Cutting Requirements
- Determine the usual size of wood you’ll be cutting – small branches, medium logs, large diameter trees?
- Consider your most frequent sawing tasks – storm cleanup, firewood processing, tree felling, milling?
- Pick the shortest bar that will comfortably handle the above needs with some extra margin.
- Consult your chainsaw owner’s manual for the optimal bar lengths, chain types, and replacements.
- Only install bar/chain combinations approved for your specific chainsaw’s engine power.
- If unsure, contact the manufacturer directly or ask at your local power equipment shop.
Equipping your chainsaw with the best bar for your usage and power output is a wise investment. Seeking out bars engineered for safety as well as specialized cutting work will improve your performance and reduce fatigue. Match your technique to the bar length. With proper maintenance and usage, a quality bar will reliably withstand years of wood cutting.
