“I was skeptical, you know? Another small chainsaw claiming big power. But the Woodshark 42cc? It surprised me. It actually surprised me.” – Frank D., Homeowner and Firewood Enthusiast.

That quote pretty much sums up what most people think when they first hear about the Woodshark 42cc chainsaw. In a market flooded with options, it’s tough to stand out. But this little saw, despite its modest displacement, has carved a niche for itself. As someone who’s spent years felling trees, bucking logs, and splitting firewood, I’ve seen a lot of chainsaws come and go. Today, I will share my insights and experiences with the Woodshark 42cc chainsaw, breaking down its engine power secrets, its strengths, and its potential weaknesses. I’ll delve into the technical aspects of this saw, compare it to other models, and provide actionable advice on how to get the most out of it.

Unveiling the Woodshark 42cc: More Than Just Cubic Centimeters

The Woodshark 42cc chainsaw isn’t going to win any awards for brute force. It’s not designed for taking down giant redwoods. But for homeowners, hobbyists, and those handling smaller tasks, it offers a compelling balance of power, weight, and price. It’s the kind of saw you can grab for limbing, pruning, clearing brush, or cutting firewood without feeling like you’re wrestling a monster.

The Heart of the Matter: Understanding the 42cc Engine

The “42cc” refers to the engine’s displacement – the total volume swept by the piston during one stroke. In simpler terms, it’s a measure of how much air and fuel the engine can suck in and burn with each cycle. More displacement usually means more power, but it’s not the whole story. Engine design, fuel delivery, and exhaust systems all play crucial roles.

The Woodshark 42cc utilizes a two-stroke engine. This means that it completes a power cycle with only one revolution of the crankshaft, compared to four-stroke engines which require two revolutions. Two-stroke engines are generally simpler, lighter, and offer a higher power-to-weight ratio, making them ideal for handheld tools like chainsaws. However, they also require a fuel mixture of gasoline and oil, and tend to be less fuel-efficient and produce more emissions than four-stroke engines.

The “Secrets” to Engine Power: It’s All in the Details

So, what makes the Woodshark 42cc punch above its weight class? It’s a combination of factors:

• Engine Tuning: The Woodshark’s engine is carefully tuned to optimize combustion. This involves precise control over fuel-air mixture, ignition timing, and exhaust flow. A well-tuned engine burns fuel more efficiently, extracting more power from each drop.
• Port Design: The design of the intake and exhaust ports (the openings that allow air and exhaust to enter and exit the cylinder) is crucial. Optimized port design improves cylinder filling and scavenging, leading to better performance.
• Lightweight Components: By using lightweight materials for components like the piston and connecting rod, the engine can rev up quicker and respond faster to changes in load. This translates to improved cutting speed and acceleration.
• High-Quality Carburetor: The carburetor is responsible for mixing air and fuel in the correct ratio. A high-quality carburetor ensures consistent and reliable fuel delivery, even under demanding conditions. The Woodshark 42cc uses a Walbro carburetor.
• Effective Exhaust System: A well-designed exhaust system reduces backpressure, allowing the engine to breathe more freely. This improves power output and fuel efficiency.

It’s not one single “secret” but rather a combination of smart engineering and careful attention to detail that allows the Woodshark 42cc to deliver surprising performance for its size.

Wood Science 101: Understanding Your Material

Before diving deeper into chainsaw operation, let’s take a detour into wood science. Understanding the properties of wood is crucial for selecting the right chainsaw, using it safely, and getting the best results.

Hardwood vs. Softwood: A Matter of Structure

The terms “hardwood” and “softwood” refer to the botanical structure of the tree, not necessarily the actual hardness of the wood. Hardwoods come from deciduous trees (trees that lose their leaves in the fall), while softwoods come from coniferous trees (trees that have needles and cones).

• Hardwoods: Generally denser and more durable than softwoods. They have a more complex cellular structure, with smaller cells and more fibers. Examples include oak, maple, cherry, and walnut.
• Softwoods: Typically lighter and easier to work with than hardwoods. They have a simpler cellular structure, with larger cells and fewer fibers. Examples include pine, fir, spruce, and cedar.

The density of wood affects its cutting resistance. Hardwoods require more power to cut than softwoods. The Woodshark 42cc is well-suited for most softwood species and smaller hardwood logs.

Moisture Content: The Key to Seasoning and Burning

Moisture content is the amount of water in wood, expressed as a percentage of the wood’s dry weight. Freshly cut (“green”) wood can have a moisture content of over 100%. Seasoned firewood, on the other hand, should have a moisture content of 20% or less.

• Why Season Firewood? Burning green wood is inefficient and produces a lot of smoke and creosote (a flammable tar that can build up in chimneys). Seasoned firewood burns hotter, cleaner, and more efficiently.
• How to Season Firewood: The key is to allow air to circulate around the wood. Stack the wood in a single row, off the ground, and in a sunny, windy location. Allow at least six months, and preferably a year or more, for the wood to dry properly. The specific time depends on the wood species and the climate.
• Moisture Meters: A moisture meter is a handy tool for checking the moisture content of firewood. Simply insert the probes into a split piece of wood and read the percentage.

Wood Anatomy: The Cellular Level

Understanding wood anatomy allows you to better understand how wood behaves when cut, split, and burned.

• Cells: Wood is composed of cells, primarily tracheids (in softwoods) and vessels (in hardwoods). These cells are elongated and aligned parallel to the grain of the wood.
• Grain: The grain refers to the alignment of the cells. Straight-grained wood is easier to split than wood with knots or twisted grain.
• Rays: Rays are cells that run perpendicular to the grain, transporting nutrients and water across the wood. They can affect the appearance and stability of the wood.
• Rings: Annual growth rings are visible on the end grain of a log. Each ring represents one year of growth. The width of the rings can indicate the tree’s growth rate and the growing conditions.

Logging Tool Selection and Maintenance Best Practices

Beyond the chainsaw, a well-equipped wood processing setup includes a variety of tools for felling, limbing, bucking, and splitting. Choosing the right tools and maintaining them properly is essential for safety, efficiency, and longevity.

Felling Tools: Axes, Wedges, and Felling Levers

• Axes: Used for felling smaller trees, limbing, and splitting small rounds. Choose an axe with a sharp blade and a comfortable handle length.
• Felling Wedges: Used to prevent a tree from pinching the chainsaw bar during felling. Drive the wedge into the back cut to lift the tree in the desired direction.
• Felling Levers: Used to help push over a tree during felling. Insert the lever into the back cut and use your body weight to apply leverage.

Limbing Tools: Hatchets, Pruning Saws, and Pole Saws

• Hatchets: Smaller versions of axes, used for limbing small branches.
• Pruning Saws: Hand saws with aggressive teeth, designed for cutting branches quickly and cleanly.
• Pole Saws: Saws mounted on a long pole, used for reaching high branches.

Bucking Tools: Chainsaws, Bow Saws, and Crosscut Saws

• Bow Saws: Hand saws with a curved frame and a narrow blade, used for bucking small logs.
• Crosscut Saws: Large hand saws with teeth designed for cutting across the grain of the wood. Used for bucking larger logs.

Splitting Tools: Mauls, Wedges, and Hydraulic Splitters

• Mauls: Heavy, blunt-headed tools used for splitting wood. Choose a maul with a weight that you can comfortably swing.
• Splitting Wedges: Used in conjunction with a maul to split tough or knotty wood.
• Hydraulic Splitters: Powered machines that use hydraulic pressure to split wood. Available in a variety of sizes and configurations, from small electric models to large gas-powered units.

I remember the first time I tried to split a particularly gnarly piece of oak with a dull maul. It was a frustrating and exhausting experience. After struggling for hours, I finally gave up and bought a hydraulic splitter. It was a game-changer. I could split in an hour what used to take me all day.

Chainsaw Maintenance: Keeping Your Saw Running Smoothly

Proper chainsaw maintenance is crucial for safety, performance, and longevity. Here are some essential maintenance tasks:

• Chain Sharpening: A sharp chain is essential for safe and efficient cutting. Sharpen the chain regularly using a file or a chainsaw sharpener.
• Chain Lubrication: Keep the chain lubricated with chainsaw bar and chain oil. Check the oil level frequently and refill as needed.
• Air Filter Cleaning: A clean air filter allows the engine to breathe properly. Clean the air filter regularly with compressed air or soap and water.
• Spark Plug Inspection: Inspect the spark plug regularly and replace it if it is fouled or damaged.
• Fuel Filter Replacement: Replace the fuel filter annually to prevent fuel starvation.
• Bar Maintenance: Clean the chainsaw bar regularly and check for wear or damage. Flip the bar periodically to distribute wear evenly.
• Carburetor Adjustment: Adjust the carburetor as needed to ensure proper fuel-air mixture.

Firewood Seasoning Techniques and Safety Considerations

Seasoning firewood properly is essential for efficient burning and reducing smoke and creosote buildup. It also significantly reduces the risk of chimney fires.

The Science of Seasoning: Evaporation and Airflow

The goal of seasoning is to reduce the moisture content of the wood to 20% or less. This is achieved through evaporation. Airflow is the key to promoting evaporation.

• Stacking Methods: The most common stacking method is the single row stack. This allows air to circulate around the wood from all sides. Other methods include the “holzhaufen” (a circular stack) and the “rick” (a long, narrow stack).
• Location, Location, Location: Choose a sunny, windy location for your firewood pile. This will maximize evaporation.
• Elevate the Wood: Stack the wood off the ground using pallets, cinder blocks, or scrap wood. This will prevent moisture from wicking up from the ground.
• Cover the Top: Cover the top of the firewood pile with a tarp or sheet of metal to protect it from rain and snow. Leave the sides open to allow for airflow.
• The Waiting Game: Allow the wood to season for at least six months, and preferably a year or more. The specific time depends on the wood species and the climate.

Firewood Safety: From Chainsaw to Fireplace

Firewood preparation and burning involve several safety considerations:

• Personal Protective Equipment (PPE): Always wear appropriate PPE when operating a chainsaw, including safety glasses, hearing protection, gloves, and sturdy boots.
• Chainsaw Safety: Follow all chainsaw safety guidelines, including proper starting procedures, cutting techniques, and maintenance practices.
• Splitting Safety: Use caution when splitting wood. Wear safety glasses and gloves, and position yourself safely away from the splitting area.
• Firewood Storage: Store firewood away from your house to prevent insect infestations and reduce the risk of fire.
• Chimney Maintenance: Have your chimney inspected and cleaned annually by a qualified professional.
• Carbon Monoxide Detectors: Install carbon monoxide detectors in your home to protect against carbon monoxide poisoning.

I had a close call a few years ago when a tree I was felling kicked back and nearly hit me. It was a sobering reminder of the importance of safety. Always take the time to assess the situation, plan your cuts carefully, and wear appropriate PPE.

Project Planning and Execution: From Tree to Firewood

Turning a standing tree into a neatly stacked pile of seasoned firewood requires careful planning and execution. Here’s a step-by-step guide:

Step 1: Tree Selection and Felling

• Tree Selection: Choose trees that are dead, diseased, or pose a safety hazard. Obtain permission from the landowner before felling any trees.
• Felling Plan: Assess the tree and its surroundings. Identify the lean of the tree, the presence of any obstacles, and the safest direction to fell the tree.
• Felling Cuts: Make a notch cut on the side of the tree facing the direction you want it to fall. Then, make a back cut on the opposite side of the tree, leaving a hinge of wood to control the fall.
• Felling Techniques: Use felling wedges or a felling lever to help push the tree over in the desired direction.

Step 2: Limbing and Bucking

• Limbing: Remove the branches from the felled tree using a chainsaw, hatchet, or pruning saw.
• Bucking: Cut the tree into manageable lengths for splitting and stacking. The ideal length depends on the size of your fireplace or wood stove.

Step 3: Splitting

• Splitting Techniques: Split the rounds using a maul, splitting wedge, or hydraulic splitter. Split the wood into pieces that are small enough to dry quickly and fit easily into your fireplace or wood stove.

Step 4: Stacking and Seasoning

• Stacking: Stack the split wood in a single row, off the ground, and in a sunny, windy location.
• Seasoning: Allow the wood to season for at least six months, and preferably a year or more.

Step 5: Burning

• Burning Techniques: Start your fire with kindling and small pieces of wood. Add larger pieces of wood as the fire builds.
• Fire Safety: Never leave a fire unattended. Keep a fire extinguisher nearby. Clean your chimney regularly.
