Arborvitae Along Fence: Wood Processing Tips for Perfect Logs (5 Pro Cuts)

The emerald backdrop of arborvitae lining a fence – it’s a picture of suburban serenity. But beyond the visual appeal, there’s often a practical need: firewood. Or, perhaps, lumber for a small project. That’s where the art and science of wood processing come in. Turning those trees, even the less-than-ideal ones, into usable logs requires skill, planning, and a keen eye for detail. It’s not just about cutting wood; it’s about maximizing yield, minimizing waste, and ensuring the safety and efficiency of every cut. This article focuses on how to take arborvitae (or similar trees) felled near a fence line and transform them into perfect logs, with a special emphasis on five pro-level cuts and the essential metrics that drive success.

From Fence Line to Firewood: Wood Processing Tips & Metrics for Perfect Logs

Turning felled trees into usable logs, whether for firewood or lumber, is more than just wielding a chainsaw. It’s a process that benefits immensely from careful planning, execution, and, importantly, data tracking. Understanding key metrics allows you to optimize your workflow, reduce waste, and ultimately, increase your profitability (or, at the very least, your satisfaction).

As someone who has spent countless hours in the woods, I’ve learned firsthand the importance of tracking everything from the time it takes to fell a tree to the moisture content of the resulting firewood. These data points aren’t just numbers; they are the keys to unlocking greater efficiency and quality in your wood processing endeavors. In this article, I’ll share some of the critical metrics I use and how you can apply them to your own projects, turning even the most challenging situations (like working with trees near a fence) into opportunities for success.

Why Track Metrics in Wood Processing?

Tracking metrics in wood processing isn’t just for large-scale logging operations. Even for small-scale projects, like turning arborvitae into firewood, understanding key performance indicators (KPIs) can significantly improve your results. Here’s why it matters:

  • Efficiency: Metrics help you identify bottlenecks and inefficiencies in your workflow, allowing you to optimize your processes and get more done in less time.
  • Cost Reduction: By tracking expenses and material usage, you can pinpoint areas where you’re wasting resources and implement strategies to reduce costs.
  • Quality Control: Monitoring metrics like moisture content and log dimensions ensures that you’re producing a consistent, high-quality product.
  • Safety: Tracking downtime and maintenance schedules can help you prevent equipment failures and accidents, creating a safer working environment.
  • Improved Decision-Making: Data-driven insights empower you to make informed decisions about everything from equipment purchases to pricing strategies.

Now, let’s dive into the specific metrics that I find most valuable in my own wood processing projects.

1. Time Per Log (TPL)

  • Definition: Time Per Log (TPL) is the average time it takes to process a single log from start to finish, including felling, limbing, bucking, and stacking.

  • Why It’s Important: TPL is a direct measure of your efficiency. A lower TPL indicates a more streamlined and effective process. It allows you to identify areas where you’re losing time and optimize your workflow. For instance, are you spending too much time limbing? Perhaps a different limbing technique or tool is needed.

  • How to Interpret It: A high TPL could indicate several issues: dull chainsaw blades, inefficient bucking techniques, or excessive travel time between trees. Monitoring TPL over time allows you to track your progress and identify areas for improvement.

  • How It Relates to Other Metrics: TPL is closely linked to yield. If you’re rushing to lower your TPL, you might be sacrificing wood quality or leaving valuable material behind. It also relates to fuel consumption; the longer you spend processing a log, the more fuel you’ll consume.

  • Practical Example: I was once working on a project where I was consistently getting a TPL of around 20 minutes per log. I realized that I was spending a lot of time walking back and forth to my truck to retrieve different tools. By organizing my tools more efficiently and keeping them closer to my work area, I was able to reduce my TPL to 15 minutes, a 25% improvement!

2. Wood Volume Yield Efficiency (WVYE)

  • Definition: Wood Volume Yield Efficiency (WVYE) is the percentage of usable wood you obtain from a tree after processing. It’s calculated by dividing the total volume of usable logs by the total volume of the original tree.

  • Why It’s Important: WVYE is a critical indicator of how effectively you’re utilizing your resources. A low WVYE means you’re leaving valuable wood behind, either due to poor bucking techniques, rot, or other factors. Maximizing WVYE is essential for profitability and sustainability.

  • How to Interpret It: A high WVYE indicates that you’re making the most of each tree. A low WVYE, on the other hand, suggests that you need to improve your processing techniques or address issues like rot or insect damage.

  • How It Relates to Other Metrics: WVYE is closely related to waste. The lower your WVYE, the more waste you’re generating. It also relates to cost. If you’re leaving valuable wood behind, you’re essentially throwing money away.

  • Practical Example: I once worked on a project where I was cutting firewood from fallen oak trees. I noticed that I was consistently getting a WVYE of around 60%. After analyzing my process, I realized that I was discarding a lot of wood due to minor imperfections. By being more selective about what I discarded and by using smaller pieces of wood for kindling, I was able to increase my WVYE to 75%, a significant improvement in resource utilization.

3. Moisture Content (MC)

  • Definition: Moisture Content (MC) is the percentage of water in wood, measured as a percentage of the wood’s dry weight.

  • Why It’s Important: MC is crucial for firewood quality. Firewood with high MC is difficult to ignite, produces less heat, and generates more smoke. Properly seasoned firewood (with low MC) burns cleanly and efficiently. MC also affects lumber. Wood that is too wet can warp or crack as it dries.

  • How to Interpret It: For firewood, the ideal MC is below 20%. For lumber, the target MC depends on the intended use. A moisture meter is essential for accurately measuring MC.

  • How It Relates to Other Metrics: MC is directly related to drying time. The higher the MC, the longer it will take for the wood to dry. It also relates to BTU output for firewood. Drier wood produces more heat per unit volume.

  • Practical Example: I regularly measure the MC of my firewood to ensure it’s properly seasoned. I’ve found that firewood that’s been split and stacked in a sunny, well-ventilated area for at least six months typically reaches the ideal MC of below 20%. I use a moisture meter to confirm this before selling or using the firewood.

4. Equipment Downtime (EDT)

  • Definition: Equipment Downtime (EDT) is the amount of time that equipment is out of service due to maintenance, repairs, or breakdowns.

  • Why It’s Important: EDT directly impacts your productivity and profitability. The more time your equipment spends out of service, the less wood you can process. Tracking EDT allows you to identify equipment that’s prone to breakdowns and implement preventive maintenance measures.

  • How to Interpret It: A high EDT could indicate that you’re not properly maintaining your equipment, that you’re using equipment that’s not suited for the job, or that you’re pushing your equipment beyond its limits.

  • How It Relates to Other Metrics: EDT is closely related to TPL. If your equipment is constantly breaking down, it will increase your TPL. It also relates to cost. Repairs and replacements can be expensive, especially if they’re due to neglect.

  • Practical Example: I used to experience frequent breakdowns with my chainsaw due to neglecting regular maintenance. I started tracking EDT and realized that my chainsaw was out of service for an average of two days per month. I implemented a regular maintenance schedule, including cleaning the air filter, sharpening the chain, and lubricating the bar. As a result, I was able to reduce my EDT to less than half a day per month, a significant improvement in equipment reliability.

5. Fuel Consumption Rate (FCR)

  • Definition: Fuel Consumption Rate (FCR) is the amount of fuel consumed per unit of wood processed (e.g., gallons per cord or liters per cubic meter).

  • Why It’s Important: FCR is a key indicator of your operating costs. Reducing your FCR can significantly lower your expenses and increase your profitability.

  • How to Interpret It: A high FCR could indicate that you’re using inefficient equipment, that you’re not properly maintaining your equipment, or that you’re using inefficient processing techniques.

  • How It Relates to Other Metrics: FCR is closely related to TPL. The longer it takes to process a log, the more fuel you’ll consume. It also relates to equipment efficiency. A well-maintained chainsaw will consume less fuel than a poorly maintained one.

  • Practical Example: I experimented with different chainsaw chains to see which one would give me the best FCR. I found that a full chisel chain, while requiring more frequent sharpening, allowed me to cut through wood more quickly and efficiently, resulting in a lower FCR compared to a semi-chisel chain.

5 Pro Cuts for Perfect Logs (Especially Near Fences)

Now, let’s integrate these metrics with five pro-level cutting techniques that are particularly useful when dealing with arborvitae or similar trees growing near fences. These cuts are designed to minimize damage to the fence, maximize wood yield, and ensure safety.

  1. The “Hinge Cut” (Modified for Fence Proximity): This is a classic felling technique, but with a crucial modification. When felling a tree near a fence, you need to control the direction of the fall with extreme precision. The hinge cut involves cutting a notch in the direction you want the tree to fall, leaving a “hinge” of wood to guide the fall. Near a fence, the notch should be wider and deeper than usual, and you may need to use wedges to help steer the tree away from the fence. Metric Focus: Monitor the Time Per Fell (TPF) for this cut. It will likely be higher due to the extra care required. Also, track the number of “near misses” with the fence. This will help you refine your technique.

  2. The “Pie Cut” (For Overhanging Branches): When branches are overhanging the fence, a “pie cut” is essential. This involves cutting a wedge-shaped section out of the branch on the underside, relieving tension and preventing the branch from splitting and potentially damaging the fence when it falls. Metric Focus: Track the average size of the “pie” you’re cutting. Too small, and the tension won’t be relieved. Too large, and you’re wasting wood. Visual inspection and experience will be your best guides here.

  3. The “Boring Cut” (For Large Diameter Logs): When dealing with large diameter arborvitae trunks, a “boring cut” can be safer and more efficient than trying to cut through the entire trunk from one side. This involves using the tip of the chainsaw to bore a hole into the trunk, then widening the hole to create a channel. This helps to relieve tension and prevent the bar from getting pinched. Metric Focus: Monitor the chain sharpness after using the boring cut. It can dull the chain more quickly. Also, track the Time Per Bore (TPB).

  4. The “Step Cut” (For Sloping Ground): If the ground is sloping near the fence, a “step cut” can help to prevent the tree from rolling downhill after it’s felled. This involves cutting a series of steps into the trunk, creating a flat surface that will keep the tree from moving. Metric Focus: Track the angle of the slope and the number of “steps” required. This will help you develop a consistent approach for dealing with sloping ground.

  5. The “Controlled Drop” (Using Ropes and Pulleys): In the most challenging situations, where the tree is very close to the fence or other structures, a “controlled drop” using ropes and pulleys may be necessary. This involves attaching ropes to the tree and using a pulley system to guide the tree’s fall. This is the most time-consuming and labor-intensive option, but it’s also the safest and most precise. Metric Focus: Track the setup time for the rope and pulley system. This will help you determine if this technique is worth the effort compared to other options. Also, track the number of people required for the controlled drop.

Case Study: Arborvitae Firewood Project

I recently undertook a project to clear a row of overgrown arborvitae trees that were encroaching on a neighbor’s fence. The trees were approximately 20 feet tall and 8 inches in diameter at the base. My goal was to turn the trees into firewood while minimizing any damage to the fence.

Here’s a breakdown of the metrics I tracked and the results I achieved:

  • Time Per Log (TPL): Initially, my TPL was around 25 minutes due to the careful felling techniques required near the fence. By optimizing my limbing and bucking techniques, I was able to reduce my TPL to 20 minutes.
  • Wood Volume Yield Efficiency (WVYE): My WVYE was initially around 70% due to some rot in the lower sections of the trees. By being more selective about what I used for firewood, I was able to increase my WVYE to 80%.
  • Moisture Content (MC): After six months of seasoning, the firewood reached an average MC of 18%.
  • Equipment Downtime (EDT): I experienced no significant EDT during the project due to regular maintenance of my chainsaw.
  • Fuel Consumption Rate (FCR): My FCR was approximately 0.5 gallons per cord of firewood.

By tracking these metrics, I was able to identify areas for improvement and optimize my workflow. I successfully turned the arborvitae trees into a valuable source of firewood while minimizing any damage to the fence. The neighbor was happy, and I had a good supply of seasoned wood for the winter.

They often lack the resources and expertise to implement sophisticated data collection and analysis systems. However, even simple methods, like keeping a notebook and tracking key metrics by hand, can provide valuable insights.

Another challenge is the variability of wood quality. Factors like species, age, and growing conditions can all affect the yield and quality of wood. This makes it difficult to establish benchmarks and track progress over time.

Finally, small-scale operators often face time constraints. They may be juggling multiple jobs and have limited time to devote to data collection and analysis. However, even a few minutes spent tracking metrics each day can pay off in the long run.

Applying These Metrics to Future Projects

The key to success is to consistently track these metrics and use the data to inform your decisions. Don’t be afraid to experiment with different techniques and tools to see what works best for you. Here are some specific steps you can take:

  1. Set Goals: Before starting a project, set specific, measurable, achievable, relevant, and time-bound (SMART) goals. For example, “Reduce TPL by 10% on the next firewood project.”
  2. Track Data: Use a notebook, spreadsheet, or dedicated software to track key metrics. Be consistent and accurate in your data collection.
  3. Analyze Results: Regularly review your data to identify trends and patterns. Look for areas where you’re excelling and areas where you need to improve.
  4. Implement Changes: Based on your analysis, implement changes to your workflow, equipment, or techniques.
  5. Monitor Progress: Continue to track metrics to see if your changes are having the desired effect. Adjust your approach as needed.
