Shortening Chainsaw Chain: Save Teeth By Removing Links? (Pro Tips)

Alright, let’s dive into the nitty-gritty of chainsaw chain shortening.

Shortening Chainsaw Chain: Save Teeth by Removing Links? (Pro Tips)

Let’s face it, replacing a chainsaw chain every time it loses a few teeth or stretches a bit can feel like throwing money into a bottomless pit. I’ve been there, done that, and bought the t-shirt (probably stained with bar oil!). The cost of running a chainsaw, especially if you’re a small-scale firewood producer or just a dedicated homeowner, adds up quickly. According to recent surveys, chainsaw chain replacement accounts for nearly 30% of total chainsaw maintenance costs for independent operators. That’s a big chunk of change! Today, I want to explore whether shortening a chainsaw chain is a viable way to extend its life and save you some hard-earned cash. We’ll look at the pros, cons, and how to do it right.

Why Bother Shortening a Chainsaw Chain? The Cost-Effectiveness Angle

The primary reason we’re even discussing this is cost. New chainsaw chains aren’t cheap. Depending on the size and type, you could easily be looking at $20 to $50 (or even more for professional-grade chains) each time you need a replacement. For someone who uses their chainsaw regularly, that cost can escalate quickly.

But it’s not just about the initial price of a new chain. There’s also the downtime involved in replacing a chain. Time is money, especially if you’re running a small business. Shortening a chain, if done correctly, can get you back up and running faster than a trip to the hardware store.

According to data from the U.S. Forest Service, professional loggers spend an average of 15 minutes replacing a chainsaw chain. While that might not seem like much, it adds up over the course of a day or a week. Now, let’s get into the meat of the matter.

Understanding Chainsaw Chain Wear and Tear

Before we grab our tools, let’s understand why we might want to shorten a chain in the first place. Chainsaw chains wear down for several reasons:

Tooth Damage: Hitting rocks, dirt, or metal can chip or break the cutting teeth.
Stretching: As the chain wears, the metal stretches, increasing the pitch (the distance between the rivets). This can cause the chain to derail and wear out the drive sprocket and bar.
General Wear: Over time, the rivets and tie straps wear down, leading to a loose and inefficient chain.

Green Wood vs. Seasoned Wood: A Factor in Chain Wear

The type of wood you’re cutting also has a significant impact on chain wear. Green wood (freshly cut) is much softer and contains a lot of moisture. While it’s generally easier to cut, the high moisture content can accelerate rust and corrosion on the chain. Seasoned wood (dried) is harder and more abrasive, leading to faster tooth wear.

My Experience: I once spent a whole winter cutting only green oak. My chains were constantly dulling and stretching. I learned the hard way that proper chain maintenance, especially frequent sharpening, is crucial when dealing with green wood.

Chainsaw Chains and Wood Species

Different wood species have varying densities and abrasive qualities, directly impacting chain wear. For instance, cutting hardwoods like oak, maple, or hickory will dull a chain much faster than cutting softwoods like pine or fir. This is because hardwoods contain more silica and other minerals that act as abrasives.

Pro Tip: Consider using a specialized chain designed for hardwoods if you frequently cut these species. These chains often have harder cutting teeth and more robust construction.

Is Shortening a Chainsaw Chain a Good Idea? The Pros and Cons

Okay, so we know why chains wear out. But is shortening them a smart move? Let’s weigh the pros and cons:

Pros:

Extends Chain Life: By removing damaged sections, you can potentially salvage a chain that would otherwise be unusable.
Cost Savings: Delaying the purchase of a new chain saves you money.
Improved Cutting Performance: A properly shortened chain can cut more efficiently than a stretched or damaged one.
Emergency Repair: Shortening a chain can be a temporary fix in the field if you don’t have a spare.

Cons:

Reduced Cutting Length: Obviously, a shorter chain means a smaller cutting capacity.
Potential for Imbalance: If you remove too many links, the chain may become unbalanced, leading to uneven wear and vibration.
Not a Permanent Solution: Shortening a chain is a temporary fix, not a replacement for proper maintenance and eventual replacement.
Safety Concerns: Improperly shortened chains can be more prone to breakage or derailment, posing a safety hazard.

Data-Backed Insights: Chain Lifespan and Maintenance

A study by the Swedish University of Agricultural Sciences found that proper chain maintenance, including regular sharpening and lubrication, can extend chain life by up to 50%. This highlights the importance of preventive care over solely relying on shortening as a solution.

When Should You Shorten a Chainsaw Chain?

Not every damaged chain is a candidate for shortening. Here are some scenarios where it might be a viable option:

Localized Damage: If you have a small section of damaged teeth due to hitting a rock or nail, shortening the chain to remove that section can be a good solution.
Stretching: If the chain has stretched significantly but the teeth are still in good condition, removing a few links can restore the proper tension.
Emergency Situation: If you’re in the middle of a job and your chain breaks, shortening it to get back to work is better than stopping altogether.

Important Note: If the chain is severely damaged, rusted, or has multiple damaged sections, it’s best to replace it. Safety should always be your top priority.

Step-by-Step Guide: How to Shorten a Chainsaw Chain

Alright, let’s get our hands dirty. Here’s a detailed guide on how to shorten a chainsaw chain:

Tools You’ll Need:

Chainsaw Chain Breaker/Spinner: This is a specialized tool for breaking and rejoining chain links. It’s essential for a clean and professional job.
Punch and Hammer: For driving out rivets if you don’t have a chain breaker.
Chain Vise: To hold the chain securely while you work.
Needle-Nose Pliers: For manipulating small parts.
File or Grinder: For smoothing any rough edges.
Safety Glasses: Protect your eyes!
Gloves: Protect your hands!

Step 1: Assess the Damage

Carefully inspect the chain to identify the damaged section(s) you want to remove. Mark the links to be removed with a marker.

Step 2: Break the Chain

Using the chain breaker/spinner, carefully break the chain at the marked points. If you don’t have a chain breaker, use a punch and hammer to drive out the rivets. Place the chain on a solid surface and support it with a small block of wood. Position the punch on the rivet head and strike it firmly with the hammer. Repeat for both rivets on the link you want to remove.

My Experience: I’ve used both chain breakers and the punch-and-hammer method. While the punch-and-hammer works in a pinch, a chain breaker is worth the investment if you plan to shorten chains regularly. It’s faster, cleaner, and less likely to damage the chain.

Step 3: Remove the Damaged Section

Carefully remove the damaged section of the chain.

Step 4: Rejoin the Chain

Now, you need to rejoin the two ends of the chain. This is where the chain breaker/spinner really shines. Align the two ends of the chain and use the spinner to press the rivets back into place. Make sure the rivets are flush with the tie straps.

If you don’t have a chain spinner, you can try using a hammer and punch to carefully peen the rivet heads. This is a more delicate process and requires a steady hand. Be careful not to damage the chain.

Step 5: Check for Free Movement

Once the chain is rejoined, make sure the links move freely. If any links are stiff, use needle-nose pliers to gently loosen them.

Step 6: File Any Rough Edges

Use a file or grinder to smooth any rough edges on the rivets or tie straps. This will prevent the chain from snagging or catching on the bar.

Step 7: Install and Test

Install the shortened chain on your chainsaw and check the tension. It should fit snugly on the bar without being too tight. Start the chainsaw and run it briefly to make sure the chain is running smoothly and not derailing.

Chainsaw Selection: Matching the Saw to the Task

Choosing the right chainsaw is crucial for both efficiency and safety. Here’s a breakdown of different chainsaw types and their ideal uses:

Light-Duty Chainsaws (Electric or Gas-Powered): These are ideal for homeowners with small yards and light trimming tasks. They typically have smaller engines (under 40cc) and shorter bars (12-16 inches).
Mid-Range Chainsaws (Gas-Powered): These are suitable for larger properties, firewood cutting, and occasional tree felling. They usually have engines in the 40-50cc range and bars between 16-20 inches.
Professional-Grade Chainsaws (Gas-Powered): These are designed for heavy-duty use, such as logging and commercial tree work. They have powerful engines (over 50cc) and bars up to 36 inches or longer.

My Experience: I started with a small electric chainsaw, thinking it would be sufficient for my needs. I quickly realized that it wasn’t powerful enough for cutting firewood. I eventually upgraded to a mid-range gas-powered saw, which has been a much better fit.

Chainsaws vs. Axes: A Modern Comparison

While axes still have their place in the wood processing world (especially for splitting), chainsaws are generally more efficient for felling trees and bucking logs. Here’s a comparison:

Speed: Chainsaws are significantly faster than axes for cutting through wood.
Effort: Chainsaws require less physical exertion than axes.
Precision: Chainsaws offer more precise cuts.
Portability: Chainsaws can be more portable than axes, especially when equipped with a lightweight bar and chain.
Cost: Chainsaws typically have a higher initial cost than axes, but the increased efficiency can offset the cost over time.

Chain Maintenance: The Key to Longevity

Shortening a chain is a temporary fix. The real secret to extending chain life is proper maintenance. Here are some essential tips:

Sharpen Regularly: A dull chain is not only less efficient, but it also puts more stress on the chainsaw engine and bar. Sharpen your chain every time you refuel or when you notice a decrease in cutting performance.
Lubricate Properly: Use a high-quality bar and chain oil to keep the chain lubricated. Check the oil level frequently and refill as needed.
Clean Regularly: Remove sawdust and debris from the chain and bar after each use. This will prevent the chain from rusting and wearing out prematurely.
Store Properly: Store your chainsaw in a dry place when not in use. This will prevent rust and corrosion.

Actionable Tips for Chain Maintenance

Use a Chain Filing Guide: This will help you maintain the correct cutting angle and depth when sharpening.
Rotate Your Chains: If you use your chainsaw frequently, consider having two or three chains that you rotate. This will allow each chain to cool down and prevent overheating.
Inspect Regularly: Check your chain for damage, wear, and proper tension before each use.

Firewood Preparation: From Log to Hearth

Now that we’ve covered chainsaw chain maintenance, let’s talk about firewood preparation. This is where all your hard work with the chainsaw pays off.

Felling Trees Safely: A Step-by-Step Guide

Felling trees is a dangerous task that should only be attempted by experienced individuals. Here’s a simplified guide to safe tree felling:

Assess the Tree: Check for dead branches, lean, and wind direction.
Clear the Area: Remove any obstacles and create a clear escape path.
Make a Notch Cut: This determines the direction of the fall.
Make a Back Cut: This severs the tree trunk.
Use Wedges (If Necessary): To help guide the fall.
Retreat Safely: Move away from the falling tree along your escape path.

Important Note: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, and chainsaw chaps.

De-Liming Procedures: Efficient and Safe

De-limbing is the process of removing branches from a felled tree. Here’s how to do it safely and efficiently:

Work from the Base to the Top: This will prevent the trunk from rolling.
Use a Sawhorse or Log as a Support: This will make it easier to cut the branches.
Cut on the Opposite Side of the Branch from Where You’re Standing: This will prevent the branch from kicking back towards you.
Be Aware of Tension: Branches can be under tension and may snap back when cut.

Splitting Logs: The Art of the Wedge

Splitting logs is a necessary step in preparing firewood. Here are a few methods:

Manual Splitting (Axe and Wedge): This is the traditional method and is still effective for smaller logs.
Hydraulic Log Splitter: This is a more efficient method for splitting larger logs.
Manual Log Splitter: A manual log splitter uses a lever to drive a wedge through the log.

My Experience: I started with a manual axe and wedge. It was hard work, but it gave me a great workout! Eventually, I invested in a hydraulic log splitter, which has saved me a lot of time and effort.

Wood Species Properties Relevant to Firewood Quality

Not all wood burns equally well. Here’s a breakdown of some common wood species and their firewood qualities:

Hardwoods (Oak, Maple, Hickory): These are dense and burn hot and long. They are excellent choices for firewood.
Softwoods (Pine, Fir, Spruce): These are less dense and burn faster. They are good for kindling or starting fires.
Fruitwoods (Apple, Cherry): These have a pleasant aroma when burned and are good for cooking.

Seasoning Firewood: Achieving Optimal Moisture Content

Seasoning firewood is the process of drying the wood to reduce its moisture content. This is essential for efficient burning and reducing smoke.

Target Moisture Content: 15-20%
Drying Time: 6-12 months (depending on the wood species and climate)
Stacking Method: Stack the wood in a single row with good air circulation.
Location: Choose a sunny and windy location.

Preparing Firewood Stacks for Optimal Drying

Elevate the Wood: Use pallets or logs to raise the wood off the ground. This will improve air circulation.
Cover the Top: Cover the top of the stack with a tarp to protect it from rain and snow.
Leave Space Between Stacks: Allow space between stacks for air circulation.

Case Study: A Successful Firewood Preparation Project

I once helped a friend prepare firewood for the winter. We felled several oak trees, de-limbed them, and bucked them into logs. We then split the logs and stacked them in a sunny location with good air circulation. After six months of seasoning, the wood was perfectly dry and burned beautifully. We calculated that we saved him over $500 compared to buying pre-cut firewood.

Data Point: Properly seasoned firewood burns approximately 25% more efficiently than green wood.

Costs, Budgeting Considerations, and Resource Management Tips

Chainsaw Costs: Consider the initial cost of the chainsaw, as well as ongoing maintenance costs (chains, oil, fuel).
Firewood Processing Tools: Budget for axes, wedges, log splitters, and other necessary tools.
Transportation Costs: Factor in the cost of transporting logs and firewood.
Labor Costs: If you’re hiring help, factor in labor costs.

Resource Management Tips:

Source Wood Locally: This will reduce transportation costs and support your local economy.
Salvage Wood: Consider using fallen trees or storm-damaged wood.
Share Resources: Partner with neighbors or friends to share equipment and labor.

Troubleshooting Guidance and Common Pitfalls to Avoid

Chainsaw Not Starting: Check the fuel, spark plug, and air filter.
Chain Dulling Quickly: Ensure proper chain lubrication and avoid cutting dirty wood.
Firewood Not Drying Properly: Ensure good air circulation and protect the wood from rain and snow.
Log Splitting Difficulties: Use a larger wedge or a hydraulic log splitter.
