Wood Processing Tools: 7 Must-Know Tips

Wood processing, whether for lumber, firewood, or crafts, involves a range of tools and techniques. Getting it right means maximizing your yield, minimizing waste, and, most importantly, staying safe. These seven tips will cover essential aspects of wood processing, from chainsaw selection to firewood stacking, with a focus on practical application and safety.

Tip 1: Chainsaw Selection and Maintenance: The Heart of Wood Processing

The chainsaw is arguably the most crucial tool in wood processing. Choosing the right one and maintaining it properly can drastically improve your efficiency and safety.

• Chainsaw Selection:

  • Engine Size: For occasional firewood cutting, a 40-50cc chainsaw is usually sufficient. For felling larger trees or frequent use, consider a 50-70cc model. Professional loggers often use 70cc+ saws.
  • Bar Length: A general rule of thumb is to choose a bar length that is at least two inches longer than the diameter of the wood you typically cut. A 16-18 inch bar is versatile for most firewood tasks. Larger trees demand longer bars (20-24 inches or more).
  • Weight: Consider the weight of the saw, especially if you’ll be using it for extended periods. Lighter saws (under 12 lbs) are easier to maneuver but may lack the power of heavier models.
  • Fuel Type: Most chainsaws use a 2-stroke engine requiring a mix of gasoline and oil. Always use the recommended oil-to-gas ratio (typically 50:1) specified by the manufacturer. Some newer models offer 4-stroke engines which eliminate the need for mixing fuel.
  • Brands: Stihl, Husqvarna, and Echo are generally considered top-tier brands known for their reliability and performance. Poulan Pro and Craftsman offer more affordable options suitable for lighter use.

• Chainsaw Maintenance:

  • Chain Sharpening: A sharp chain is essential for safe and efficient cutting. I recommend sharpening the chain after every two to three tanks of fuel. Use a chainsaw file and follow the manufacturer’s instructions for the correct filing angle and depth. Alternatively, you can use a chainsaw sharpener.
  • Chain Tension: Check the chain tension before each use. The chain should be snug against the bar but still able to be pulled around by hand. Too loose, and the chain can derail; too tight, and it can overheat and break.
  • Bar Lubrication: Ensure the chain oiler is functioning correctly. The chain should be constantly lubricated during operation. Use a high-quality bar and chain oil.
  • Air Filter: Clean the air filter regularly to prevent engine damage. A dirty air filter can restrict airflow and cause the engine to overheat.
  • Spark Plug: Inspect the spark plug periodically and replace it if necessary. A fouled spark plug can cause the engine to run poorly or not start at all.
  • Fuel Filter: Replace the fuel filter annually to prevent fuel contamination.
  • Case Study: I once worked on a project clearing a heavily wooded lot. A colleague neglected to maintain his chainsaw properly. The chain was dull, the bar oiler was clogged, and the air filter was filthy. As a result, he was working twice as hard and experiencing frequent kickbacks, significantly increasing his risk of injury. After a thorough cleaning, sharpening, and lubrication, his saw performed like new, and his productivity increased dramatically.

• Safety Considerations:

  • Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet with a face shield, hearing protection, gloves, chainsaw chaps, and sturdy boots.
  • Kickback: Be aware of the risk of kickback, which occurs when the tip of the bar comes into contact with an object. Use a chainsaw with a chain brake and practice proper cutting techniques to minimize the risk.
  • Working Alone: Avoid working alone, especially when felling trees. If you must work alone, let someone know your location and expected return time.
  • First Aid Kit: Keep a well-stocked first aid kit on hand and know how to use it.

Tip 2: Mastering Felling Techniques: Directional Control is Key

Felling trees safely and efficiently is a critical skill for anyone involved in wood processing. Proper felling techniques ensure the tree falls where you intend it to, minimizing damage to surrounding trees and structures.

• Assessing the Tree:

  • Lean: Determine the natural lean of the tree. Trees tend to fall in the direction of their lean.
  • Wind: Consider the wind direction. Wind can significantly affect the direction of fall.
  • Obstacles: Identify any obstacles, such as other trees, power lines, or buildings, that could interfere with the fall.
  • Dead Limbs: Check for dead or hanging limbs that could fall unexpectedly.

• Felling Cuts:

  • Undercut: The undercut is a notch cut into the tree on the side you want it to fall. It should be at least one-third of the tree’s diameter. There are several types of undercuts, including the conventional undercut (45-degree angle) and the Humboldt undercut (two angled cuts meeting at a point). The Humboldt undercut is particularly effective for larger trees.
  • Back Cut: The back cut is made on the opposite side of the tree from the undercut. It should be slightly higher than the undercut and leave a hinge of wood to control the direction of fall.
  • Hinge: The hinge is the uncut wood between the undercut and the back cut. It acts as a guide, directing the tree’s fall. The width and thickness of the hinge are crucial for controlling the fall.

• Felling Aids:

  • Felling Wedges: Felling wedges are used to help push the tree over in the desired direction. They are inserted into the back cut and driven in with a hammer or axe.
  • Felling Lever: A felling lever is a long-handled tool used to apply leverage to the tree, helping to push it over.
  • Pulling Rope: In some cases, a pulling rope can be attached to the tree and used to pull it in the desired direction. This is particularly useful for trees with a strong lean in the wrong direction.

• Safety Considerations:

  • Escape Route: Plan an escape route before making any cuts. The escape route should be at a 45-degree angle away from the direction of fall.
  • Bystanders: Ensure that no bystanders are within a safe distance of the tree. The safe distance is typically at least twice the height of the tree.
  • Communication: Use clear communication with any partners working with you.

• Case Study: I once had to fell a large oak tree that was leaning precariously towards a house. The challenge was to fell the tree away from the house without damaging any surrounding structures. I carefully assessed the tree, taking into account its lean, the wind direction, and the proximity of the house. I used a Humboldt undercut and a felling wedge to control the direction of fall. The tree fell exactly where I wanted it to, without causing any damage. The key was meticulous planning and precise execution of the felling cuts.

Tip 3: Bucking and Limbing: Preparing Logs for Processing

Bucking is the process of cutting felled trees into shorter lengths, while limbing involves removing the branches. These steps are essential for preparing logs for further processing, such as milling or splitting.

• Bucking Techniques:

  • Log Support: Ensure the log is properly supported to prevent it from pinching the chainsaw bar. Use log supports or other logs to elevate the log off the ground.
  • Cutting Methods: Several cutting methods can be used, depending on the size and position of the log. These include:
    • Overbucking: Cutting from the top down.
    • Underbucking: Cutting from the bottom up.
    • Boring: Inserting the tip of the chainsaw bar into the log and cutting outwards.
  • Spring Poles: Be aware of the danger of spring poles, which are small trees or branches that are bent under tension. These can snap back with considerable force when cut.

• Limbing Techniques:

  • Working Position: Position yourself on the uphill side of the log to avoid being struck by rolling logs or falling branches.
  • Cutting Angle: Cut the branches close to the trunk, but avoid damaging the bark.
  • Safety Considerations: Be aware of the risk of kickback when limbing. Use a chainsaw with a chain brake and maintain a firm grip on the saw.

• Tools for Bucking and Limbing:

  • Chainsaw: The primary tool for bucking and limbing.
  • Axe: Useful for removing smaller branches and splitting small logs.
  • Cant Hook: A long-handled tool used to roll logs.
  • Peavey: Similar to a cant hook, but with a spike on the end for gripping logs.

• Case Study: I once worked on a project clearing a large area of pine trees. The trees were relatively small, but there were a lot of them. To speed up the bucking and limbing process, I used a combination of techniques. I first limbed the trees while they were still standing, using a chainsaw to remove the branches. Then, I felled the trees and bucked them into firewood lengths using a log support to prevent pinching. This approach significantly increased my productivity compared to felling and bucking each tree individually.

Tip 4: Log Splitting: Manual vs. Hydraulic

Splitting logs is a necessary step in preparing firewood. You can split logs manually with an axe or maul, or you can use a hydraulic log splitter. Each method has its advantages and disadvantages.

• Manual Splitting:

  • Tools:
    • Axe: Suitable for splitting smaller logs. A splitting axe has a wider head than a felling axe.
    • Maul: A heavier tool with a blunt head, designed for splitting larger logs.
    • Wedges: Used to split particularly tough or knotty logs.
    • Sledgehammer: Used to drive wedges into logs.
  • Technique: Place the log on a solid surface, such as a stump or log splitting block. Position the axe or maul on the log and swing with sufficient force to split it.
  • Advantages:
    • Inexpensive
    • Quiet
    • Good exercise
  • Disadvantages:
    • Labor-intensive
    • Time-consuming
    • Can be dangerous

• Hydraulic Log Splitters:

  • Types:
    • Electric: Suitable for home use.
    • Gas-Powered: More powerful and portable, suitable for larger jobs.
  • Splitting Force: Log splitters are rated by their splitting force, measured in tons. A 20-ton splitter is sufficient for most firewood tasks. Larger logs may require a 30-ton or higher splitter.
  • Cycle Time: The cycle time is the time it takes for the splitter to complete one splitting cycle. A shorter cycle time means faster splitting.
  • Advantages:
    • Fast and efficient
    • Requires less physical effort
    • Safer than manual splitting
  • Disadvantages:
    • More expensive than manual tools
    • Noisy
    • Requires maintenance

• Safety Considerations:

  • Manual Splitting: Wear safety glasses and gloves. Keep your feet firmly planted and maintain a safe distance from the log.
  • Hydraulic Log Splitters: Wear safety glasses and gloves. Keep your hands away from the splitting wedge. Follow the manufacturer’s instructions for safe operation.

• Case Study: I used to split all my firewood manually with an axe and maul. It was a great workout, but it was also incredibly time-consuming and tiring. After switching to a hydraulic log splitter, my productivity increased dramatically. I could split a cord of wood in a fraction of the time, and I was much less fatigued at the end of the day. While the initial investment in a log splitter was significant, the time and effort it saved me made it well worth it.

Tip 5: Wood Identification and Selection: Know Your Wood

Different types of wood have different properties that make them suitable for different purposes. Understanding the characteristics of different wood species can help you choose the best wood for your needs, whether it’s for firewood, construction, or woodworking.

• Hardwoods vs. Softwoods:

  • Hardwoods: Generally denser and heavier than softwoods. They burn longer and produce more heat. Examples include oak, maple, ash, and birch.
  • Softwoods: Generally less dense and lighter than hardwoods. They burn faster and produce less heat. Examples include pine, fir, spruce, and cedar.

• Firewood Characteristics:

  • Heat Value: The amount of heat produced when burning a given volume of wood. Hardwoods generally have a higher heat value than softwoods.
  • Seasoning: The process of drying wood to reduce its moisture content. Seasoned wood burns more efficiently and produces less smoke.
  • Smoke Production: Some woods produce more smoke than others. Woods with high resin content, such as pine, tend to produce more smoke.
  • Sparking: Some woods, such as pine, tend to spark and throw embers when burned.

• Woodworking Characteristics:

  • Grain: The pattern of the wood fibers. Different wood species have different grain patterns.
  • Workability: How easy the wood is to work with, including cutting, shaping, and finishing.
  • Strength: The ability of the wood to withstand stress.
  • Durability: The ability of the wood to resist decay and insect damage.

• Examples of Common Wood Species:

  • Oak: A dense hardwood with a high heat value. It is slow to season but burns cleanly and produces little smoke.
  • Maple: A dense hardwood with a high heat value. It is easier to split than oak and seasons relatively quickly.
  • Ash: A hardwood with a high heat value. It splits easily and seasons quickly.
  • Birch: A hardwood with a moderate heat value. It burns quickly and produces a pleasant aroma.
  • Pine: A softwood with a low heat value. It burns quickly and produces a lot of smoke. It is often used for kindling.
  • Cedar: A softwood with a low heat value. It is resistant to decay and insect damage, making it suitable for outdoor projects.

• Case Study: I once built a shed using a combination of wood species. I used pressure-treated pine for the framing because it is resistant to decay. I used cedar for the siding because it is attractive and durable. And I used oak for the door because it is strong and stable. By selecting the right wood species for each component, I was able to build a shed that was both functional and long-lasting.

Tip 6: Seasoning Firewood: Patience is a Virtue

Seasoning firewood is the process of drying it to reduce its moisture content. Green wood (freshly cut wood) can have a moisture content of 50% or more. Seasoned firewood should have a moisture content of 20% or less. Burning green wood is inefficient, produces a lot of smoke, and can contribute to creosote buildup in your chimney, increasing the risk of a chimney fire.

• Methods of Seasoning:

  • Air Drying: The most common method of seasoning firewood. It involves stacking the wood in a well-ventilated area and allowing it to dry naturally.
  • Kiln Drying: A faster method of seasoning firewood that involves placing the wood in a kiln and heating it to a specific temperature.
  • Solar Drying: A method of seasoning firewood that involves using solar energy to heat the wood.

• Air Drying Techniques:

  • Stacking: Stack the firewood in a single row, with the bark side up. This helps to prevent moisture from being trapped in the wood.
  • Elevation: Elevate the wood off the ground using pallets or other supports. This allows air to circulate underneath the wood.
  • Ventilation: Ensure the wood is exposed to plenty of air circulation. Avoid stacking the wood in a damp or shaded area.
  • Sunlight: Expose the wood to sunlight. Sunlight helps to evaporate moisture from the wood.
  • Covering: Cover the top of the woodpile with a tarp to protect it from rain and snow. However, leave the sides open to allow for ventilation.

• Seasoning Time:

  • Hardwoods: Generally require 6-12 months of seasoning.
  • Softwoods: Generally require 3-6 months of seasoning.
  • Climate: In drier climates, firewood will season faster than in humid climates.

• Checking for Seasoning:

  • Moisture Meter: Use a moisture meter to measure the moisture content of the wood.
  • Appearance: Seasoned firewood will be lighter in color and have cracks in the end grain.
  • Sound: When two pieces of seasoned firewood are struck together, they will produce a hollow sound.
  • Weight: Seasoned firewood will be lighter than green firewood.

• Case Study: I once had a customer who insisted on burning green firewood. He complained that his stove was not producing enough heat and that his chimney was constantly clogged with creosote. After inspecting his firewood, I found that it had a moisture content of over 40%. I explained to him the importance of seasoning firewood and recommended that he switch to seasoned wood. After switching to seasoned wood, his stove produced more heat, his chimney stayed cleaner, and he saved money on firewood.

Tip 7: Firewood Storage: Keeping it Dry and Organized

Proper firewood storage is essential for keeping your firewood dry and preventing it from rotting. It also helps to keep your woodpile organized and accessible.

• Location:

  • Dry: Choose a location that is dry and well-drained.
  • Ventilated: Ensure the location is well-ventilated to allow air to circulate around the wood.
  • Accessible: Choose a location that is easily accessible, especially during the winter months.
  • Away from Buildings: Store firewood away from buildings to reduce the risk of insect infestation and fire.

• Storage Methods:

  • Firewood Racks: Firewood racks are a convenient way to store firewood. They keep the wood off the ground and allow for good air circulation.
  • Pallets: Pallets can be used to elevate the firewood off the ground.
  • Lean-to: A lean-to can be built to protect the firewood from rain and snow.
  • Tarp: A tarp can be used to cover the top of the woodpile. However, leave the sides open to allow for ventilation.

• Stacking Techniques:

  • Crisscross Stacking: A method of stacking firewood in which the logs are laid perpendicular to each other, creating a stable and well-ventilated stack.
  • Holz Hausen: A circular method of stacking firewood that is particularly effective for drying wood.
  • Rows: Stacking firewood in rows is a simple and efficient method.

• Pest Control:

  • Inspect: Inspect the firewood for signs of insects before storing it.
  • Remove Bark: Remove the bark from the firewood to reduce the risk of insect infestation.
  • Store Away from Buildings: Store firewood away from buildings to prevent insects from entering your home.

• Case Study: I once visited a customer who had a massive woodpile that was completely disorganized and overgrown with weeds. The wood was damp and rotting, and it was infested with insects. I helped him to clean up the woodpile, sort the wood, and stack it properly on pallets. After the cleanup, his woodpile was much more organized, the wood was drying properly, and he had significantly reduced the risk of insect infestation. He was amazed at the difference that proper firewood storage made.
