Wood Anatomy and Properties: A Deep Dive

To truly understand the differences between hemlock and cedar, we need to delve into the fascinating world of wood anatomy and properties. This isn’t just dry textbook stuff; it’s the foundation for making informed decisions about which wood to use for your shelter.

Softwood vs. Hardwood: The Starting Point

Both hemlock and cedar are softwoods, meaning they come from coniferous trees (trees with needles and cones). Softwoods are generally easier to work with than hardwoods, lighter in weight, and often more readily available. However, not all softwoods are created equal.

Cellular Structure: The Key to Understanding

The properties of wood are largely determined by its cellular structure. Wood is composed of cells, primarily tracheids in softwoods, which are long, tube-like structures that transport water and nutrients throughout the tree. The arrangement, size, and composition of these cells influence the wood’s density, strength, and resistance to decay.

Density: Denser wood is generally stronger and more durable. Density is measured in pounds per cubic foot (lbs/ft³).
Grain: The grain refers to the alignment of the wood cells. Straight-grained wood is easier to split and work with, while wood with knots or irregular grain can be more challenging.
Resin Content: Resin is a sticky substance found in many softwoods. It can help protect the wood from insects and decay, but it can also make it more difficult to finish.
Moisture Content: The amount of water in wood is crucial. Green wood (freshly cut) has a high moisture content, while seasoned wood has been dried to a lower moisture content. Moisture content affects the wood’s weight, strength, and stability.

Hemlock: A Closer Look

Eastern Hemlock (Tsuga canadensis) and Western Hemlock (Tsuga heterophylla) are the most common species.

Color: Hemlock typically has a light brown to reddish-brown color.
Grain: It generally has a straight, uniform grain.
Density: Hemlock has a moderate density, typically around 29 lbs/ft³ when dry.
Workability: Hemlock is relatively easy to work with, accepting nails and screws well.
Decay Resistance: Hemlock has poor decay resistance, making it unsuitable for direct ground contact unless treated.
Moisture Content Dynamics: Hemlock tends to absorb and release moisture relatively quickly, which can lead to dimensional changes if not properly seasoned.
Unique Insights: Hemlock’s splinter-free nature makes it a safe option for projects where children might be present.

Cedar: A Closer Look

There are several species of cedar, including Western Red Cedar (Thuja plicata) and Eastern White Cedar (Thuja occidentalis). Western Red Cedar is the most commonly used for construction.

Color: Cedar has a distinctive reddish-brown color with variations depending on the species.
Grain: It has a straight grain, often with knots.
Density: Cedar is a lightweight wood, typically around 23 lbs/ft³ when dry.
Workability: Cedar is easy to work with, splitting easily and accepting fasteners well.
Decay Resistance: Cedar is naturally decay-resistant due to the presence of thujaplicins, chemicals that inhibit fungal growth. This is its biggest advantage.
Moisture Content Dynamics: Cedar is more stable than hemlock, meaning it is less prone to warping or cracking due to changes in moisture content.
Unique Insights: The aromatic oils in cedar act as a natural insect repellent.

Logging Tool Selection and Maintenance Best Practices

Before you can even think about building a shelter, you need to get your hands on the wood. That means felling trees, and that requires the right tools and the knowledge to use them safely and effectively. I remember one time when I tried to fell a large oak with a dull axe… let’s just say it was a long and frustrating day.

Chainsaws: The Workhorse of Logging

The chainsaw is the primary tool for felling trees. Choosing the right chainsaw depends on the size of the trees you’ll be cutting and the frequency of use.

Gas-Powered Chainsaws: These are the most common type, offering high power and portability. Look for models with features like anti-vibration systems and automatic chain oilers.
- Example: A Stihl MS 271 Farm Boss is a great all-around chainsaw for smaller logging operations.
Electric Chainsaws: These are quieter and easier to maintain than gas-powered chainsaws, but they have less power and require access to an electrical outlet or battery.
Chainsaw Safety Gear: Never, ever operate a chainsaw without proper safety gear. This includes:
- Helmet with Face Shield: Protects your head and face from falling debris.
- Hearing Protection: Chainsaws are loud; protect your hearing with earplugs or earmuffs.
- Chainsaw Chaps: These protect your legs from accidental cuts.
- Gloves: Provide a better grip and protect your hands.
- Steel-Toed Boots: Protect your feet from falling logs and sharp objects.

Axes and Wedges: The Traditional Tools

While chainsaws are efficient, axes and wedges are still valuable tools for felling trees and splitting wood.

Felling Axe: Used for making the initial cuts when felling a tree.
Splitting Axe: Designed for splitting logs along the grain.
Wedges: Used to help direct the fall of a tree or to split stubborn logs. Steel wedges are common, but plastic or wooden wedges are safer for use with chainsaws (they won’t damage the chain if accidentally struck).

Logging Tool Maintenance

Proper maintenance is essential for keeping your logging tools in good working order and ensuring your safety.

Chainsaw Maintenance:
- Sharpen the Chain Regularly: A sharp chain cuts faster and safer. Use a chainsaw file or a chain grinder to sharpen the chain.
- Clean the Air Filter: A clogged air filter reduces the engine’s power.
- Check the Chain Tension: A loose chain can derail and cause injury.
- Lubricate the Chain: Use chainsaw bar oil to keep the chain lubricated and prevent it from overheating.
Axe Maintenance:
- Sharpen the Blade: Use a file or a sharpening stone to keep the blade sharp.
- Check the Handle: Make sure the handle is securely attached to the head.
Wedge Maintenance:
- Inspect for Damage: Check for cracks or chips in the wedge.
- Keep the Striking Surface Clean: Remove any debris from the striking surface to ensure a solid blow.

Case Study: A Logging Project Gone Wrong

I once worked on a logging project where the crew neglected to maintain their chainsaws. The chains were dull, the air filters were clogged, and the chains were constantly derailing. As a result, the project took much longer than expected, and there were several near-miss accidents. This experience taught me the importance of prioritizing tool maintenance.

Data Points and Statistics

Chainsaw Chain Sharpening: A dull chainsaw chain can increase cutting time by up to 50% and fuel consumption by 20%.
Axe Sharpening: A sharp axe requires 30% less force to cut through wood compared to a dull axe.

Firewood Seasoning Techniques and Safety Considerations

Whether you’re building a shelter for long-term habitation or just for a weekend getaway, firewood is essential for warmth, cooking, and light. However, burning green wood is inefficient and produces a lot of smoke. Seasoning firewood properly is crucial.

The Science of Seasoning

Seasoning firewood involves reducing its moisture content to around 20% or less. This allows the wood to burn more efficiently and produce more heat. Green wood can have a moisture content of 50% or higher.

Evaporation: The primary method of seasoning is evaporation. As the wood sits in the open air, water evaporates from the cells.
Fungal Decay: While some fungal decay can occur during seasoning, it’s generally minimal if the wood is properly stacked and ventilated.

Seasoning Techniques

Stacking: Stack the firewood in a single row, off the ground, with plenty of space between the rows for air circulation.
Sunlight: Expose the wood to direct sunlight as much as possible.
Wind: Choose a location with good wind exposure to promote evaporation.
Covering: Cover the top of the woodpile to protect it from rain and snow, but leave the sides open for ventilation.
Time: Seasoning typically takes 6-12 months, depending on the species of wood and the climate.

Firewood Safety Considerations

Stacking Stability: Make sure the woodpile is stable and won’t collapse.
Clearance: Keep the woodpile away from buildings and flammable materials.
Pest Control: Be aware of potential pests, such as termites and carpenter ants, and take steps to prevent them from infesting your firewood.
Fire Safety: Have a fire extinguisher or a water source nearby when burning firewood.
Carbon Monoxide: Never burn firewood in an enclosed space without proper ventilation. Carbon monoxide is a deadly, odorless gas.

Firewood Seasoning and Hemlock vs Cedar

While cedar dries relatively quickly due to its lower density, hemlock requires more time and attention to prevent rot during the seasoning process. Proper stacking and ventilation are even more crucial for hemlock.

Fuel Value Ratings

Different wood species have different fuel value ratings, measured in British Thermal Units (BTUs) per cord.

Hemlock: Around 16 million BTUs per cord.
Cedar: Around 13 million BTUs per cord.

While hemlock has a slightly higher BTU rating, the difference is not significant enough to outweigh cedar’s superior decay resistance in a shelter context.

Practical Tips

Split Firewood Before Seasoning: Splitting the wood increases the surface area exposed to the air, speeding up the seasoning process.
Use a Moisture Meter: A moisture meter can help you determine when your firewood is properly seasoned.
Rotate Your Firewood: Rotate your firewood supply to ensure that the oldest wood is burned first.
Avoid Burning Green Wood: Burning green wood can damage your chimney and increase the risk of a chimney fire.

My Personal Experience

I once tried to save time by burning green hemlock in my wood stove. The result was a smoky, inefficient fire that coated my chimney with creosote.

Cost-Benefit Analysis

While cedar is more expensive than hemlock, its superior decay resistance can save you money in the long run by reducing the need for repairs and replacements. A cost-benefit analysis can help you determine which wood is the best value for your project.

Original Research and Case Studies

I conducted a small-scale experiment by building two identical lean-to shelters, one with cedar siding and one with hemlock siding. After five years, the cedar siding showed no signs of decay, while the hemlock siding was starting to rot in several places. This experiment confirmed my belief that cedar is the better choice for exterior components.

Key Considerations for Different Shelter Types

Temporary Shelters (e.g., for camping): Hemlock may suffice if treated, given its lower cost and ease of work. Focus on portability and quick assembly.
Semi-Permanent Shelters (e.g., hunting cabins): Cedar is highly recommended for long-term durability, especially in areas with high moisture.
Permanent Dwellings: A combination of both can be effective, using cedar for exterior and hemlock for interior components, maximizing cost-effectiveness and longevity.
