Northern Tool Stihl Chainsaws Review (Expert Firewood Tips)

Imagine a crisp autumn afternoon, leaves swirling like confetti as a child, eyes wide with wonder, watches their grandfather expertly wield a chainsaw, transforming a fallen tree into a winter’s worth of warmth. That image, that connection to nature and the satisfaction of self-sufficiency, is what fuels many of us in the wood processing and firewood preparation world. But beyond the romanticism, there’s a practical side – a need to understand efficiency, cost, and quality. And that’s where tracking project metrics becomes crucial. In this article, I’ll share my experiences and insights on how to measure success in this field, focusing on key performance indicators (KPIs) that can significantly improve your operations, whether you’re a seasoned professional or just starting out. Let’s dive in!

Decoding the Chainsaw’s Song: Project Metrics for Wood Processing and Firewood Mastery

Why bother with metrics? Because without them, you’re operating in the dark. You might think you’re efficient, but data tells the true story. Tracking these metrics allows you to identify bottlenecks, optimize processes, reduce waste, and ultimately, increase profitability (or, at the very least, reduce your personal firewood costs!). It’s about making informed decisions, not just relying on gut feelings.

The User Intent: The user is looking for a review of Stihl chainsaws available at Northern Tool, specifically for firewood preparation, and expert tips on using chainsaws for this purpose. They likely want to know which Stihl chainsaw model is best for their needs, considering factors like power, bar length, weight, and cost. They also seek practical advice on safe and efficient chainsaw operation for firewood cutting.

Here’s a breakdown of crucial project metrics, presented with actionable insights and real-world examples.

1. Wood Volume Yield Efficiency

• Definition: This metric measures the percentage of usable wood obtained from a raw log or tree, compared to the total volume of the original material. It’s essentially how much firewood or lumber you get versus how much you started with.

• Why It’s Important: High yield efficiency directly translates to lower material costs and increased profitability. Minimizing waste reduces the need to purchase more raw materials, saving you money and labor.

• How to Interpret It: A low yield efficiency indicates significant waste. This could be due to poor cutting techniques, inefficient equipment, or low-quality raw materials. A high yield efficiency means you’re maximizing the use of your resources.

• How It Relates to Other Metrics: This metric is closely tied to wood waste (see metric #3) and cutting time (see metric #5). Reducing cutting time and minimizing waste directly improves yield efficiency. It also relates to material costs (see metric #10), as higher efficiency means lower cost per unit of usable wood.

• Practical Example: Let’s say you start with a log that’s 10 cubic feet. After processing, you have 7 cubic feet of usable firewood. Your wood volume yield efficiency is 70%. Now, if you adjust your bucking techniques and reduce waste, and your yield increases to 8.5 cubic feet, your efficiency jumps to 85%. That 15% increase translates directly into more firewood from the same log, saving you money and time.

• My Experience: I once worked on a project where we were processing a large quantity of storm-damaged oak. Initially, our yield efficiency was around 60% due to inexperienced workers and dull chainsaws. By providing proper training on cutting techniques and investing in better saw maintenance, we were able to increase the yield to 75% within a month. This resulted in a significant increase in our overall profitability.

2. Moisture Content Levels

• Definition: This refers to the amount of water present in the 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 hotter, cleaner, and more efficiently than wet wood. High moisture content leads to smoky fires, reduced heat output, and increased creosote buildup in chimneys, which is a fire hazard.

• How to Interpret It: Firewood ideally should have a moisture content below 20%. Freshly cut wood can have moisture levels as high as 50% or even higher. The lower the moisture content, the better the firewood.

• How It Relates to Other Metrics: This metric is directly related to drying time (see metric #6). Proper stacking and seasoning techniques (drying) are essential for reducing moisture content. It also affects burn time (see metric #9) and fuel efficiency.

• Practical Example: You cut a batch of oak firewood in the spring. Its initial moisture content is 45%. After properly stacking and seasoning it for six months, the moisture content drops to 18%. This firewood will burn much more efficiently and cleanly than if you had tried to burn it immediately after cutting.

• My Experience: I learned this lesson the hard way. Years ago, I was eager to burn some freshly cut pine in my wood stove. The fire was smoky, produced very little heat, and coated my chimney with creosote. After that experience, I invested in a moisture meter and always check the moisture content of my firewood before burning it. A good moisture meter is a worthwhile investment.

3. Wood Waste Percentage

• Definition: This represents the percentage of wood that is unusable or discarded during the processing or firewood preparation process. This includes sawdust, bark, irregularly shaped pieces, and wood damaged by insects or rot.

• Why It’s Important: Minimizing wood waste reduces material costs, disposal fees, and environmental impact. It also increases overall efficiency and profitability.

• How to Interpret It: A high wood waste percentage indicates inefficiencies in the process. This could be due to poor cutting techniques, inefficient equipment, or low-quality raw materials. A low percentage means you’re maximizing the use of your resources.

• How It Relates to Other Metrics: This metric is inversely related to wood volume yield efficiency (see metric #1). Reducing wood waste directly improves yield efficiency. It also relates to material costs (see metric #10) and disposal costs.

• Practical Example: You process 100 cubic feet of logs and generate 20 cubic feet of wood waste. Your wood waste percentage is 20%. By optimizing your cutting techniques and using a more efficient wood splitter, you reduce the waste to 10 cubic feet, bringing the waste percentage down to 10%. This means you have 10 more cubic feet of usable firewood from the same amount of raw material.

• My Experience: I discovered that the type of chainsaw chain I was using significantly impacted wood waste. A full-chisel chain, while faster, produced more sawdust than a semi-chisel chain. For certain types of wood, switching to a semi-chisel chain reduced sawdust waste by 5%. This seemingly small change added up to significant savings over time.

4. Equipment Downtime

• Definition: This is the amount of time equipment (chainsaws, wood splitters, log loaders, etc.) is out of service due to maintenance, repairs, or breakdowns.

• Why It’s Important: Downtime directly impacts productivity and increases labor costs. Frequent breakdowns disrupt workflow and can lead to missed deadlines.

• How to Interpret It: High downtime indicates potential problems with equipment maintenance, operator training, or the quality of the equipment itself. Low downtime means your equipment is running reliably and efficiently.

• How It Relates to Other Metrics: Downtime affects cutting time (see metric #5), processing time, and overall project completion time. It also impacts labor costs (see metric #8) and material costs (if delays lead to spoiled wood).

• Practical Example: Your chainsaw breaks down frequently, resulting in an average of 2 hours of downtime per week. By implementing a regular maintenance schedule (cleaning, sharpening, lubrication) and training operators on proper usage, you reduce the downtime to 30 minutes per week. This frees up 1.5 hours per week for actual wood processing, increasing your productivity.

• My Experience: I once tried to save money by buying a cheap, off-brand chainsaw. It broke down constantly, costing me more in repairs and downtime than I would have spent on a quality Stihl chainsaw in the first place. I learned that investing in reliable equipment is crucial for long-term efficiency and cost savings. Proper chain sharpening is key to minimizing chainsaw downtime. A dull chain puts extra strain on the engine and can lead to premature wear and tear.

5. Cutting Time per Unit Volume

• Definition: This measures the amount of time it takes to cut a specific volume of wood (e.g., minutes per cubic foot).

• Why It’s Important: Cutting time directly impacts labor costs and overall production rate. Reducing cutting time increases efficiency and allows you to process more wood in a given time period.

• How to Interpret It: A high cutting time indicates potential problems with cutting techniques, equipment efficiency, or the hardness of the wood. A low cutting time means you’re cutting efficiently.

• How It Relates to Other Metrics: This metric is closely tied to equipment downtime (see metric #4), wood volume yield efficiency (see metric #1), and labor costs (see metric #8). Improving cutting techniques and using efficient equipment reduces cutting time, improves yield, and lowers labor costs.

• Practical Example: It takes you 15 minutes to cut one cubic foot of oak with a dull chainsaw. After sharpening the chain and improving your cutting technique, you reduce the cutting time to 10 minutes per cubic foot. This 33% reduction in cutting time translates to a significant increase in your overall productivity.

• My Experience: I realized that proper body positioning and stance while using the chainsaw made a huge difference in cutting time and fatigue. By adopting a more ergonomic posture and using my body weight effectively, I could cut for longer periods without getting tired, and I was also able to cut faster. Learning proper limbing techniques is another way to improve cutting time. Removing branches efficiently reduces the overall time spent preparing the logs for bucking.

6. Drying Time to Target Moisture Content

• Definition: This is the amount of time it takes for firewood to dry to a target moisture content (ideally below 20%).

• Why It’s Important: Drying time affects the availability of firewood for sale or personal use. Reducing drying time allows you to turn raw wood into usable firewood more quickly.

• How to Interpret It: A long drying time indicates potential problems with stacking techniques, location, or weather conditions. A short drying time means your firewood is drying efficiently.

• How It Relates to Other Metrics: This metric is directly related to moisture content levels (see metric #2) and stacking density (see metric #7). Proper stacking techniques and a well-ventilated location reduce drying time.

• Practical Example: You stack your firewood in a dense pile in a shaded area. It takes 12 months to dry to a moisture content below 20%. By restacking the firewood in a loose pile in a sunny, well-ventilated location, you reduce the drying time to 6 months.

• My Experience: I experimented with different stacking methods and found that elevated stacks, allowing airflow underneath, dried significantly faster than stacks placed directly on the ground. I also discovered that covering the top of the stack with a tarp, while leaving the sides open, protected the wood from rain and snow while still allowing it to breathe. This reduced drying time by several weeks.

7. Stacking Density

• Definition: This refers to the tightness or looseness of the firewood stack, measured in terms of volume of wood per unit volume of stack (e.g., cubic feet of wood per cubic foot of stack).

• Why It’s Important: Stacking density affects airflow and drying time. A loose stack promotes airflow, which speeds up drying, while a dense stack restricts airflow and can slow down drying.

• How to Interpret It: A very dense stack may hinder drying, while a very loose stack may take up too much space. The ideal stacking density balances airflow with space efficiency.

• How It Relates to Other Metrics: This metric is directly related to drying time to target moisture content (see metric #6) and space utilization. It also indirectly affects fuel efficiency (see metric #9) because properly dried wood burns better.

• Practical Example: You stack your firewood in a very dense pile, filling every available space. The stack takes up a small area, but it takes a long time to dry. By restacking the firewood in a looser pile with more air gaps, you increase the drying rate, even though the stack now occupies a slightly larger area.

• My Experience: I found that using pallets as a base for my firewood stacks created an air gap that significantly improved airflow and reduced drying time. This also helped to prevent the bottom layer of wood from rotting. I also realized that the orientation of the wood in the stack matters. Stacking the wood with the split faces exposed to the air promotes faster drying.

8. Labor Costs per Unit Volume

• Definition: This measures the total labor costs associated with processing a specific volume of wood (e.g., dollars per cubic foot).

• Why It’s Important: Labor costs are a significant expense in wood processing and firewood preparation. Reducing labor costs increases profitability.

• How to Interpret It: High labor costs indicate potential inefficiencies in the process or high labor rates. Low labor costs mean you’re operating efficiently.

• How It Relates to Other Metrics: This metric is closely tied to cutting time per unit volume (see metric #5), equipment downtime (see metric #4), and overall project completion time. Improving efficiency in these areas reduces labor costs.

• Practical Example: It takes two workers 8 hours to process 10 cubic feet of firewood, and their combined hourly wage is $40. Your labor cost per cubic foot is $32 ($40/hour x 8 hours / 10 cubic feet). By investing in a more efficient wood splitter and training the workers on better techniques, you can reduce the processing time to 6 hours. This lowers the labor cost per cubic foot to $24.

• My Experience: I discovered that investing in good quality personal protective equipment (PPE) not only improved safety but also increased worker productivity. Workers who felt safe and comfortable were able to work more efficiently and for longer periods without fatigue. Proper training on safe chainsaw operation and wood splitting techniques also reduced the risk of injuries, which could lead to costly workers’ compensation claims and lost productivity.

9. Burn Time and Heat Output

• Definition: Burn time refers to how long a specific volume of firewood burns. Heat output refers to the amount of heat produced by the burning firewood, typically measured in BTUs (British Thermal Units).

• Why It’s Important: These metrics are crucial for assessing the quality and value of firewood. Longer burn times and higher heat output mean the firewood is more efficient and provides more warmth.

• How to Interpret It: Short burn times and low heat output indicate low-quality firewood, likely due to high moisture content or the type of wood. Long burn times and high heat output mean you have high-quality firewood.

• How It Relates to Other Metrics: These metrics are directly related to moisture content levels (see metric #2) and wood species. Drier wood and denser wood species generally burn longer and produce more heat.

• Practical Example: You burn one cubic foot of freshly cut pine. It burns quickly and produces very little heat. You then burn one cubic foot of seasoned oak with a moisture content of 15%. It burns much longer and produces significantly more heat.

• My Experience: I found that mixing different types of wood in the firebox provided a more consistent and efficient burn. For example, I would use a combination of faster-burning softwoods (like pine or fir) to get the fire started quickly, and then add slower-burning hardwoods (like oak or maple) to maintain a consistent heat output. I also learned that the size of the wood pieces affected burn time. Smaller pieces burned faster, while larger pieces burned slower.

10. Material Costs per Unit Volume

• Definition: This measures the cost of raw materials (logs, trees) required to produce a specific volume of firewood (e.g., dollars per cubic foot).

• Why It’s Important: Material costs are a major expense in firewood production. Reducing material costs increases profitability.

• How to Interpret It: High material costs indicate that you’re paying too much for raw materials or that you’re not using them efficiently. Low material costs mean you’re sourcing materials effectively.

• How It Relates to Other Metrics: This metric is closely tied to wood volume yield efficiency (see metric #1) and wood waste percentage (see metric #3). Improving yield efficiency and reducing waste lowers material costs.

• Practical Example: You purchase logs for $50 per cubic foot. After processing, you only get 0.5 cubic feet of usable firewood from each cubic foot of logs. Your material cost per cubic foot of firewood is $100. By improving your cutting techniques and reducing waste, you increase the yield to 0.75 cubic feet of firewood per cubic foot of logs. This lowers the material cost per cubic foot of firewood to $66.67.

• My Experience: I learned the importance of negotiating prices with log suppliers and exploring alternative sources of raw materials. For example, I was able to obtain storm-damaged trees at a significantly lower cost than commercially harvested logs. I also discovered that purchasing logs in bulk often resulted in a lower per-unit cost. Building strong relationships with local landowners and logging companies can also provide access to a steady supply of affordable raw materials.
