From Felling to Fuel: Why Track Metrics?
I remember a time when I thought meticulous record-keeping was only for big corporations. I was wrong. Whether you’re a small-scale firewood producer or managing a large logging operation, tracking key metrics is crucial for profitability, efficiency, and safety. It’s about understanding where your resources are going, identifying areas for improvement, and making informed decisions that impact your bottom line. Think of it as a GPS for your wood processing journey. Without it, you’re just wandering in the woods, hoping to stumble upon success.
Part 1: Mastering Safe Tree Felling Techniques for Dead Trees
Assessing the Risk: The Foundation of Safe Felling
Before even touching a chainsaw, a thorough risk assessment is paramount. Dead trees present unique hazards. Unlike live trees, their structural integrity is compromised, making them unpredictable and prone to sudden collapse. I always start with a 360-degree inspection, looking for the following:
- Extent of Decay: How much of the tree is rotten? Are there visible signs of fungal growth, insect infestation, or hollow sections?
- Lean: Is the tree leaning significantly? A dead tree with a lean is a recipe for disaster if not addressed properly.
- Wind Conditions: Wind can dramatically increase the risk of felling a dead tree. Avoid felling on windy days if possible.
- Surroundings: Are there any obstacles in the felling zone, such as power lines, buildings, or roads?
- Escape Route: Always plan a clear escape route that is free of obstacles and at a 45-degree angle away from the anticipated direction of fall.
Choosing the Right Tools: Chainsaws and Beyond
Selecting the right tools is crucial for safe and efficient felling.
- Chainsaw: A well-maintained chainsaw with a sharp chain is essential. The size of the saw should be appropriate for the size of the tree. I prefer using a slightly larger saw than I would for a live tree, as dead wood can be harder to cut.
- Wedges: Wedges are used to prevent the saw from pinching and to help direct the fall of the tree. Plastic or aluminum wedges are preferred over steel wedges, as they are less likely to damage the chain if accidentally contacted.
- Felling Lever: A felling lever provides leverage to help push the tree over. This is particularly useful for smaller trees or trees with a slight lean.
- Personal Protective Equipment (PPE): This is non-negotiable. Always wear a helmet, eye protection, hearing protection, chainsaw chaps, and sturdy boots.
Felling Techniques Tailored for Dead Trees
The felling technique used will depend on the size, lean, and condition of the tree. However, here are some general guidelines:
- The Bore Cut: The bore cut involves plunging the tip of the chainsaw into the tree to create a hinge. This technique is particularly useful for controlling the direction of fall and preventing barber chairing (when the tree splits upward). I use this frequently on dead trees to control the fall. It requires experience and caution.
- The Conventional Notch and Back Cut: Create a notch on the side of the tree facing the direction you want it to fall. The notch should be about one-third of the tree’s diameter. Then, make a back cut on the opposite side of the tree, leaving a hinge of wood to control the fall.
- Dealing with Lean: If the tree is leaning, use wedges to help push it over in the desired direction. You may also need to use a winch or come-along to provide additional force.
- Hung-Up Trees: If the tree gets hung up in another tree, do not attempt to climb the tree to dislodge it. This is extremely dangerous. Instead, use a winch or come-along to pull the tree down from the ground.
- Cutting from the Top Down: In extreme cases, where the tree is severely decayed or leaning precariously, it may be necessary to cut the tree down in sections from the top down. This is a dangerous technique that should only be attempted by experienced arborists.
Safety First: A Constant Vigil
Safety must always be the top priority. Never work alone when felling trees, especially dead ones. Have a spotter who can watch for hazards and provide assistance. Before making any cuts, clear the area of debris and ensure that everyone is a safe distance away.
Part 2: Key Metrics for Wood Processing & Firewood Preparation
Now, let’s move on to the data-driven side of wood processing and firewood preparation. Here are the key metrics I track in my operations, and why they matter:
1. Wood Volume Yield Efficiency (WVYE)
- Definition: This is the ratio of usable wood produced (firewood, lumber, etc.) to the total volume of raw wood processed. It’s expressed as a percentage.
- Why It’s Important: WVYE directly impacts profitability. A higher WVYE means less waste and more saleable product from the same amount of raw material.
- How to Interpret It: A WVYE of 80% means that 80% of the raw wood processed ends up as usable product. A lower percentage indicates inefficiencies in the process.
- How It Relates to Other Metrics: WVYE is closely related to wood waste percentage (Metric 2) and equipment downtime (Metric 5). High downtime can lead to increased waste and lower yield.
-
Personal Story & Data: In one of my firewood projects, I started with a WVYE of around 65%. By optimizing my cutting techniques, reducing chainsaw downtime, and improving my splitting process, I increased it to 82% within six months. This translated to a significant increase in profits. Let’s say I started with 10 cords of raw wood at $100/cord and sold firewood at $300/cord.
- Initial WVYE (65%): 10 cords raw wood -> 6.5 cords firewood = Revenue of 6.5 * $300 = $1950. Profit = $1950 – $1000 (raw wood cost) = $950.
- Improved WVYE (82%): 10 cords raw wood -> 8.2 cords firewood = Revenue of 8.2 * $300 = $2460. Profit = $2460 – $1000 (raw wood cost) = $1460.
That’s a $510 increase in profit from the same amount of raw material! * Actionable Insight: Regularly measure WVYE and identify the factors contributing to low yield. This could include poor cutting techniques, inefficient equipment, or inadequate storage practices.
Case Study 1: Small-Scale Firewood Producer
A small-scale firewood producer was struggling to make a profit. He tracked his WVYE and found it to be only 55%. After analyzing his process, he realized that he was losing a lot of wood due to improper bucking techniques and inefficient splitting. He implemented a training program for himself and his helper on proper bucking techniques and invested in a more efficient splitter. As a result, he increased his WVYE to 75% and significantly improved his profitability.
Case Study 2: Logging Operation
A logging operation was experiencing high equipment downtime. They tracked EDT for each piece of equipment and found that their chainsaws were the biggest source of downtime. They implemented a regular maintenance schedule for their chainsaws, including daily sharpening and cleaning. They also trained their operators on proper chainsaw operation and maintenance. As a result, they reduced their chainsaw downtime by 40% and increased their overall productivity.
Case Study 3: Firewood Delivery Service
A firewood delivery service was receiving complaints from customers about wet firewood. They started using a moisture meter to check the MCL of their firewood before delivery. They also implemented a covered storage system to protect the firewood from rain. As a result, they eliminated customer complaints about wet firewood and improved their customer satisfaction rating.
Part 4: Applying Metrics to Improve Future Projects
Tracking these metrics is not a one-time exercise. It’s an ongoing process of continuous improvement. Here’s how to apply these metrics to improve your future wood processing and firewood preparation projects:
- Set Goals: Define specific, measurable, achievable, relevant, and time-bound (SMART) goals for each metric. For example, “Reduce wood waste percentage from 20% to 15% within six months.”
- Track Progress: Regularly monitor your progress towards your goals. Use spreadsheets, software, or even a simple notebook to track your data.
- Analyze Data: Identify trends and patterns in your data. What factors are contributing to your success? What factors are holding you back?
- Implement Changes: Based on your analysis, implement changes to your processes, equipment, or training programs.
- Evaluate Results: After implementing changes, monitor your metrics to see if they have improved. If not, re-evaluate your approach and try something different.
- Repeat: Continue this cycle of setting goals, tracking progress, analyzing data, implementing changes, and evaluating results. This is the key to continuous improvement.
