Investing in success means more than just buying a new chainsaw or splitting maul. It’s about investing in the knowledge to use your tools effectively and efficiently. In the world of wood processing and firewood preparation, that knowledge comes from understanding and tracking key metrics. I’ve seen firsthand how meticulous record-keeping can transform a struggling operation into a thriving one. Whether you’re a weekend warrior felling trees for personal use or running a full-scale firewood business, understanding project metrics is crucial for maximizing yield, minimizing waste, and ultimately, putting more money in your pocket. This guide will break down the essential metrics you need to track, offering practical advice and actionable insights based on my years of experience. We’ll delve into the specifics of using older chains on new 20″ bars with a Husqvarna 353, but the principles apply to any chainsaw and wood processing setup.

Why Track Metrics?

Before we dive into the specifics, let’s address the fundamental question: why bother tracking metrics in the first place? The answer is simple: what gets measured, gets managed. Without tracking, you’re essentially flying blind. You might be working hard, but you won’t know if you’re working smart.

Tracking metrics allows you to:

• Identify inefficiencies: Pinpoint areas where you’re wasting time, materials, or money.
• Optimize processes: Refine your techniques and workflows to improve productivity.
• Make informed decisions: Base your choices on data rather than gut feeling.
• Improve profitability: Increase yield, reduce waste, and lower costs.
• Monitor equipment performance: Track maintenance needs and prevent costly breakdowns.

Think of it like this: you wouldn’t drive a car without a speedometer or fuel gauge. Similarly, you shouldn’t run a wood processing operation without tracking key performance indicators (KPIs).

Essential Wood Processing & Firewood Preparation Metrics

Here are the core metrics I use to assess and improve my wood processing and firewood preparation projects. Each metric is presented with a clear definition, its importance, how to interpret it, and its relationship to other metrics.

1. Cost Per Cord (CPC)

• Definition: The total cost incurred to produce one cord of firewood (or another unit of processed wood, like board feet). This includes all expenses, from raw materials to labor and equipment.
• Why it’s Important: CPC is the ultimate measure of profitability. It tells you how much it costs to produce your product, allowing you to determine a profitable selling price.
• How to Interpret it: A lower CPC is always better. Track your CPC over time to identify trends and areas for cost reduction. Compare your CPC to market prices to ensure you’re competitive.
• How it Relates to Other Metrics: CPC is directly influenced by many other metrics, including raw material cost, labor cost, equipment downtime, and wood waste. Improving these metrics will lower your CPC.
• Example: I once worked with a small firewood operation that was struggling to make a profit. They were selling firewood at what they thought was a reasonable price, but they weren’t tracking their costs. After implementing a system to track CPC, they discovered that their actual cost per cord was significantly higher than they had estimated. This allowed them to identify areas where they were wasting money (e.g., inefficient cutting practices, excessive equipment downtime) and make changes to improve their profitability.
• Actionable Insight: Break down your CPC into its component parts (raw materials, labor, equipment, etc.) to identify the biggest cost drivers. Focus your efforts on reducing these costs.

2. Raw Material Cost (RMC)

• Definition: The cost of the raw wood used in your processing operation. This includes the cost of standing timber, purchased logs, or salvaged wood.
• Why it’s Important: Raw material cost is often the single largest expense in wood processing. Minimizing this cost is crucial for profitability.
• How to Interpret it: Track your RMC per unit of output (e.g., per cord, per board foot). Look for opportunities to negotiate better prices with suppliers, utilize lower-cost wood species, or salvage wood from alternative sources.
• How it Relates to Other Metrics: RMC directly impacts CPC. It also relates to wood volume yield, as maximizing yield from each log reduces the overall RMC per unit of output.
• Example: I remember a project where we were sourcing logs from a local sawmill. After analyzing our RMC, we realized we were paying a premium for certain species that weren’t essential for our end product. By switching to a lower-cost species that still met our quality requirements, we significantly reduced our RMC and improved our profitability.
• Actionable Insight: Explore different sources of raw wood to find the most cost-effective options. Consider utilizing wood waste from other operations (e.g., sawmill slabs, logging slash) as a low-cost alternative.

3. Labor Cost (LC)

• Definition: The total cost of labor involved in your wood processing operation. This includes wages, benefits, and payroll taxes for all employees involved in felling, processing, and handling wood.
• Why it’s Important: Labor cost can be a significant expense, especially in labor-intensive operations. Optimizing labor efficiency is crucial for reducing costs and improving productivity.

• Example: A friend of mine runs a small sawmill and was struggling to dispose of the large amount of sawdust he was generating. After researching alternative uses for sawdust, he started selling it as mulch for gardens and landscaping. This not only eliminated his disposal costs but also generated a new revenue stream.
• Actionable Insight: Identify the sources of wood waste in your operation. Explore alternative uses for waste materials, such as firewood, mulch, bioenergy, or animal bedding. Invest in equipment and techniques that minimize waste generation.

7. Time Per Cord (TPC)

• Definition: The amount of time required to produce one cord of firewood (or another unit of processed wood).
• Why it’s Important: TPC is a measure of efficiency. Reducing the time it takes to produce each unit of output will increase productivity and lower labor costs.
• How to Interpret it: Track your TPC over time to identify trends and areas for improvement. Compare your TPC to industry benchmarks to assess your performance.
• How it Relates to Other Metrics: TPC is directly influenced by labor cost, equipment downtime, and wood volume yield. Improving these metrics will reduce your TPC.
• Example: I once participated in a firewood cutting competition. The goal was to cut and split one cord of firewood as quickly as possible. By using efficient techniques and working as a team, we were able to significantly reduce our TPC and win the competition. This experience highlighted the importance of teamwork, proper technique, and efficient equipment.
• Actionable Insight: Analyze your workflow to identify bottlenecks and areas for improvement. Invest in training and equipment to improve efficiency. Consider implementing time-saving techniques, such as pre-splitting logs or using a hydraulic log splitter.

8. Moisture Content (MC)

• Definition: The amount of water present in wood, expressed as a percentage of the wood’s dry weight.
• Why it’s Important: Moisture content is crucial for firewood quality. Dry firewood burns more efficiently and produces less smoke and creosote.
• How to Interpret it: Measure the MC of your firewood using a moisture meter. Aim for an MC of 20% or less for optimal burning.
• How it Relates to Other Metrics: MC affects the drying time, which impacts the time to market and storage costs.
• Example: A neighbor of mine sold “seasoned” firewood that was actually quite wet. Customers complained about the difficulty in lighting the wood and the excessive smoke it produced. By investing in a moisture meter and properly drying his firewood, he was able to improve his product quality and customer satisfaction.
• Actionable Insight: Invest in a moisture meter to monitor the MC of your firewood. Properly season your firewood by stacking it in a well-ventilated area for at least six months. Consider using a kiln to accelerate the drying process.

9. Chainsaw Chain Life (CCL)

• Definition: The amount of time or volume of wood cut before a chainsaw chain needs sharpening or replacement.
• Why it’s Important: CCL impacts both productivity and cost. A longer chain life reduces downtime for sharpening and replacement, while also minimizing the cost of replacement chains.
• How to Interpret it: Track the hours of use or volume of wood cut per chain. Identify factors that affect chain life, such as wood species, cutting conditions, and sharpening technique.
• How it Relates to Other Metrics: CCL affects TPC, EDT, and CPC. Longer chain life reduces downtime and costs, improving overall efficiency.
• Example: I meticulously tracked the lifespan of my chainsaw chains, and discovered that using a high-quality chain oil significantly extended the CCL compared to cheaper alternatives. The initial investment in better oil paid off in the long run through reduced chain replacements and downtime.
• Actionable Insight: Use high-quality chain oil, sharpen chains regularly, and avoid cutting dirty or abrasive materials. Consider using a different chain type for different wood species or cutting conditions. Also, ensure the bar is properly maintained and not worn.

10. Bar Wear Rate (BWR)

• Definition: The rate at which a chainsaw bar wears down, typically measured by the amount of material lost over time or use.
• Why it’s Important: Excessive bar wear can lead to poor cutting performance, increased chain wear, and potentially dangerous situations.
• How to Interpret it: Regularly inspect your chainsaw bar for signs of wear, such as burrs, grooves, or uneven surfaces. Track the amount of time or volume of wood cut before the bar needs replacement.
• How it Relates to Other Metrics: BWR affects CCL, TPC, and EDT. A worn bar can cause the chain to dull quickly, increasing downtime and reducing cutting efficiency.
• Example: I once neglected to properly maintain my chainsaw bar, and it eventually developed a deep groove that caused the chain to bind and overheat. This not only reduced cutting efficiency but also increased the risk of kickback. By replacing the bar and implementing a regular maintenance schedule, I was able to improve performance and safety.
• Actionable Insight: Regularly inspect your chainsaw bar for signs of wear. File down any burrs or grooves. Keep the bar lubricated with high-quality chain oil. Replace the bar when it becomes excessively worn. Ensure proper chain tension to avoid uneven wear.

The Husqvarna 353 & Older Chains on New 20″ Bars: A Specific Case Study

Now, let’s address the specific scenario outlined in the original user intent: using older chains on a new 20″ bar with a Husqvarna 353. This presents a unique set of considerations that can significantly impact your project metrics.

Challenges and Considerations:

• Chain Pitch and Gauge: Ensure that the older chains have the correct pitch and gauge for the new 20″ bar and the Husqvarna 353. Using the wrong chain can damage the bar, the saw, and potentially cause injury.
• Chain Length: A 20″ bar requires a specific number of drive links. Older chains may be too short, especially if they were previously used on a shorter bar.

• Bar Compatibility: Even if the pitch and gauge are correct, some older chains may not be ideally suited for the design of the new bar.

Impact on Metrics:

• CCL: Using older chains will likely reduce their lifespan compared to using new chains. The existing wear and tear will accelerate further deterioration.
• BWR: A worn chain can put excessive stress on the bar, potentially increasing the BWR.
• TPC: Dull or poorly fitting chains will significantly increase the time it takes to cut wood.
• Safety: Using mismatched or worn components increases the risk of chain breakage, kickback, and other safety hazards.

Recommendations:

• Inspect the Chains Thoroughly: Before using older chains on a new bar, carefully inspect them for wear, damage, and proper fit.
• Consider the Cost-Benefit: Weigh the cost of new chains against the potential risks and reduced performance of using older chains. In most cases, investing in new chains is the more cost-effective and safer option.
• Proper Sharpening: If you decide to use older chains, ensure they are properly sharpened to maximize their performance and lifespan.
• Monitor Performance: Closely monitor the performance of the chains and the bar. If you notice any signs of excessive wear or poor cutting performance, replace the chains immediately.
• Consult a Professional: If you’re unsure about the compatibility of older chains with your new bar, consult a qualified chainsaw mechanic.

Personal Experience:

I once tried to save money by using a collection of old chains on a new bar. I thought I was being resourceful, but the results were disastrous. The chains were mismatched, poorly sharpened, and caused the bar to overheat and wear down quickly. In the end, I spent more time and money on repairs and replacements than I would have if I had simply invested in new chains from the start.

Applying Metrics to Improve Future Projects

Tracking these metrics is only the first step. The real value comes from using this data to improve your future wood processing and firewood preparation projects.

Here’s how I use project metrics to drive continuous improvement:

1. Regularly Review Data: Set aside time each week or month to review your project metrics. Look for trends, anomalies, and areas where you can improve.
2. Identify Root Causes: When you identify a problem area (e.g., high equipment downtime, low wood volume yield), dig deeper to understand the root causes. Ask “why” repeatedly until you uncover the underlying issues.
3. Implement Solutions: Develop and implement solutions to address the root causes of your problems. This might involve changing your workflow, investing in new equipment, or providing additional training to your workers.
4. Monitor Results: Track your metrics after implementing solutions to see if they are having the desired effect. Make adjustments as needed.
5. Document Lessons Learned: Keep a record of your project metrics, the problems you encountered, the solutions you implemented, and the results you achieved. This will help you learn from your mistakes and avoid repeating them in the future.

Case Study: Improving Firewood Drying Time

In one of my firewood preparation projects, I noticed that my drying time was consistently longer than expected. After analyzing my metrics, I identified two key factors:

• Poor Air Circulation: The firewood stacks were too tightly packed, restricting airflow.
• High Initial Moisture Content: The logs were not being allowed to dry sufficiently before being split and stacked.

To address these issues, I made the following changes:

• Improved Stacking Technique: I started using a looser stacking technique that allowed for better air circulation.
• Pre-Drying Logs: I allowed the logs to dry for several weeks before splitting them.

As a result of these changes, I was able to significantly reduce my drying time and improve the quality of my firewood.

Final Thoughts

Mastering wood processing and firewood preparation is a journey of continuous learning and improvement. By embracing project metrics and using data to drive your decisions, you can optimize your operations, improve your profitability, and achieve your goals. Don’t be afraid to experiment, learn from your mistakes, and adapt your approach as needed. The more you understand your processes and the more data you collect, the better equipped you’ll be to succeed in this challenging but rewarding field. And remember, safety always comes first!
