Stihl MS171 Chain Size Guide (5 Pro Tips for Sharp Cutting)

Understanding the Stihl MS 171 Chain: Size and Specifications

The Stihl MS 171 typically uses a chain with a 3/8″ low profile (Picco Micro 3) pitch and a 0.050″ (1.3mm) gauge. The number of drive links will vary depending on the bar length. Common bar lengths for the MS 171 are 14″ and 16″.

• 14″ Bar: Usually requires a chain with 50 drive links.
• 16″ Bar: Usually requires a chain with 55 drive links.

Important Note: Always consult your chainsaw’s manual or the stamping on the guide bar to confirm the correct chain specifications. Using the wrong chain can damage your saw and be dangerous.

Why is chain size so critical?

Using the correct chain size ensures proper engagement with the sprocket and guide bar. A chain that’s too loose can derail, causing injury. A chain that’s too tight puts excessive strain on the saw’s motor and can lead to premature wear. Pitch refers to the distance between three rivets divided by two, while gauge is the thickness of the drive links where they fit into the guide bar.

5 Pro Tips for Sharp Cutting with Your MS 171

1. Choose the Right Chain Type: While the standard Picco Micro 3 is a good all-around chain, consider specialized chains for specific tasks. For example, if you’re cutting a lot of dirty or abrasive wood, a chain with hardened cutters will hold its edge longer.
2. Sharpen Regularly: A dull chain is a dangerous chain. It requires more force to cut, increasing the risk of kickback and putting unnecessary strain on the saw. Sharpen your chain every time you refuel, or more frequently if you notice it’s struggling to cut.
3. Maintain Proper Chain Tension: The chain should be snug against the guide bar but still able to be pulled around by hand. Check the tension frequently, especially when the chain is new, as it will stretch during the initial break-in period.
4. Lubricate Properly: Use a high-quality bar and chain oil to keep the chain lubricated. This reduces friction, prevents overheating, and extends the life of both the chain and the guide bar. Check the oil level frequently and refill as needed.
5. Clean and Inspect Regularly: After each use, clean the chain and guide bar with a brush and solvent to remove sawdust and debris. Inspect the chain for damage, such as cracked or broken cutters, and replace it if necessary. Also, flip the bar regularly to ensure even wear.

The Real Costs of Wood Processing: A Personal Perspective

I’ve been working with wood for over 20 years, from felling trees on my family’s property to processing firewood for our wood stove. Over that time, I’ve learned that the initial cost of a chainsaw like the MS 171 is just the tip of the iceberg. The true cost of wood processing involves a complex interplay of factors, including material costs, labor, equipment maintenance, and even the value of your own time.

One year, I decided to take on a large firewood project, aiming to process enough wood to last us two winters. I figured I could save a significant amount of money compared to buying seasoned firewood. What I didn’t fully account for were the hidden costs. I underestimated the amount of time it would take, the wear and tear on my equipment, and the sheer physical labor involved. By the end of the project, I realized that while I did save some money, the savings weren’t as substantial as I had initially anticipated. This experience taught me the importance of careful planning and accurate cost estimation.

Breaking Down the Cost Components: A Systematic Approach

To accurately budget for wood processing, we need to break down all the cost components. Here’s a systematic approach:

1. Material Costs (Timber Acquisition):

   • Standing Timber: If you’re felling your own trees, there might not be a direct purchase cost, but there’s still an opportunity cost. What else could you do with that land? If you’re buying standing timber, prices vary wildly depending on species, quality, and location.
   • Purchased Logs: Prices for logs are typically quoted per board foot or per cord. A board foot is a unit of volume equal to 144 cubic inches (e.g., a piece of wood 12″ x 12″ x 1″). A cord is a stacked volume of wood measuring 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet. Prices can range from \$50 to \$500+ per cord, depending on the species and location.
   • Firewood Rounds: Purchasing firewood in round form (uncut logs) is often cheaper than buying split firewood, but it requires more labor on your part. Prices typically range from \$100 to \$300 per cord.

   • Tool Costs:

   • Chainsaw (Initial Investment): The Stihl MS 171 typically costs between \$200 and \$300 new.
   • Chainsaw Maintenance: This includes the cost of replacement chains, bar oil, sharpening files, and occasional repairs. A good quality chain can cost between \$20 and \$40. Bar oil typically costs around \$10-\$20 per gallon. Sharpening files cost a few dollars each.
   • Splitting Maul or Log Splitter: A splitting maul costs around \$50 to \$100. A gas-powered log splitter can cost anywhere from \$1,000 to \$4,000, depending on its size and power. You can also rent log splitters for around \$50 to \$100 per day.
   • Safety Gear: This is non-negotiable. Invest in a good quality helmet with a face shield and ear protection (around \$50-\$100), chainsaw chaps (around \$100-\$200), and work gloves (around \$20-\$40).
   • Other Tools: This might include wedges, a sledgehammer, a cant hook (for rolling logs), and measuring tools.

   • Labor Costs:

   • Your Time: Don’t underestimate the value of your time. How much is your time worth per hour? Factor this into your calculations.

   • Hired Labor: If you’re hiring a logging crew or firewood handlers, labor costs can be a significant expense. Logging crews typically charge by the hour, day, or by the amount of timber harvested. Firewood handlers may charge by the cord. Average labor rates can range from \$20 to \$50+ per hour, depending on experience and location.

   • Transportation Costs:

   • Fuel: Hauling logs or firewood requires fuel for your truck or trailer.
   • Vehicle Maintenance: Heavy loads can put extra strain on your vehicle, leading to increased maintenance costs.

   • Permits and Fees:

   • Logging Permits: In some areas, you may need a permit to fell trees, especially on public land. These permits can cost anywhere from a few dollars to hundreds of dollars, depending on the location and the scope of the project.

   • Firewood Cutting Permits: Some national forests and state parks require permits to collect firewood. These permits are usually relatively inexpensive, but it’s important to obtain them to avoid fines.

   • Drying and Storage Costs:

   • Storage Space: You’ll need a dry place to store your firewood. If you don’t have a shed or garage, you may need to build or rent one.
   • Tarps: Tarps can be used to protect firewood from rain and snow.

   • Miscellaneous Costs:

   • Unexpected Repairs: Equipment can break down unexpectedly, leading to repair costs.

   • Medical Expenses: Wood processing can be dangerous, and injuries can occur. Factor in the potential cost of medical expenses.

Data-Backed Insights: Timber Prices, Equipment Rental Fees, and Fuelwood Market Rates

To provide a clearer picture of the costs involved, let’s look at some data-backed insights:

• Timber Prices: According to the US Forest Service, the average stumpage price (the price paid for standing timber) for sawtimber in the United States in 2022 was around \$300 per thousand board feet (MBF). However, this price can vary significantly depending on the species and location. For example, high-quality hardwoods like black walnut can fetch prices of \$1,000+ per MBF.
• Equipment Rental Fees: Home Depot and other equipment rental companies typically charge around \$75 to \$125 per day for a gas-powered log splitter. Skid steer loaders, often used in larger logging operations, can cost \$200-\$400 per day to rent.
• Fuelwood Market Rates: According to the Hearth, Patio & Barbecue Association (HPBA), the average price for a cord of seasoned firewood in the United States in 2023 was around \$250. However, prices can range from \$150 to \$400+ per cord, depending on the location, species, and dryness of the wood. In some areas, especially in urban centers, the price can be even higher.

Regional Variations: It’s crucial to remember that these are just averages. Timber prices, equipment rental fees, and fuelwood market rates can vary significantly depending on your location. For example, firewood is typically more expensive in areas with colder climates and limited access to forests.

Original Research and Case Studies: Budgeting and Cost Management

To illustrate the importance of budgeting and cost management, let’s consider a hypothetical case study:

Case Study: John’s Firewood Project

John decides to process 5 cords of firewood for his wood stove. He owns a Stihl MS 171 chainsaw and plans to split the wood by hand using a splitting maul. He estimates that he can purchase logs for \$150 per cord.

Here’s a breakdown of his estimated costs:

• Logs (5 cords x \$150/cord): \$750
• Chainsaw Maintenance (chain, bar oil, sharpening): \$100
• Splitting Maul (already owns): \$0
• Safety Gear (already owns): \$0
• Fuel (for truck): \$50
• His Time (50 hours x \$20/hour): \$1,000 (This is an opportunity cost – what else could he be doing with this time?)

Total Estimated Cost: \$1,900

Based on these estimates, John calculates that his cost per cord of firewood will be \$380 (\$1,900 / 5 cords). This is significantly higher than the average market price for seasoned firewood in his area (around \$250 per cord).

Analysis:

John’s case study highlights the importance of factoring in the value of your time. While he may be saving some money on the logs themselves, the amount of time he’s spending processing the firewood is significantly increasing his overall cost.

Cost Optimization Strategies:

• Consider Renting a Log Splitter: Renting a log splitter could significantly reduce the amount of time it takes to split the wood, potentially offsetting the rental cost.
• Negotiate a Better Price for Logs: Shop around for the best price on logs.
• Process the Wood More Efficiently: Streamline your workflow to reduce the amount of time it takes to process each cord of wood.

Practical Tips for Cost Optimization and Budget Management

Here are some practical tips for cost optimization and budget management in wood processing or firewood preparation projects:

• Plan Ahead: Develop a detailed plan that outlines all the steps involved in the project, from acquiring the timber to storing the finished firewood.

• Negotiate Prices: Don’t be afraid to negotiate prices with suppliers and contractors.
• Buy in Bulk: Purchase logs or firewood rounds in bulk to take advantage of volume discounts.
• Maintain Your Equipment: Regularly maintain your chainsaw, log splitter, and other equipment to prevent costly breakdowns.
• Sharpen Your Chains Regularly: A sharp chain cuts faster and requires less effort, saving you time and fuel.
• Dry Your Firewood Properly: Properly dried firewood burns more efficiently, reducing the amount of wood you need to burn. Aim for a moisture content of 20% or less.
• Track Your Expenses: Keep track of all your expenses to see where your money is going and identify areas where you can save.
• Consider Bartering: If you have skills or resources that others need, consider bartering for logs or labor.
• Take Advantage of Free Resources: Many state and federal agencies offer free resources on wood processing and firewood preparation.

Relevant Calculations and Formulas

Here are some relevant calculations and formulas that can be helpful in budgeting for wood processing:

• Estimating the Volume of Logs in Board Feet:

  • Doyle Log Rule: (Small End Diameter in Inches – 4)² x Length in Feet / 16
  • Scribner Log Rule: (0.79 x Small End Diameter in Inches² ) – (2 x Small End Diameter in Inches) – (4 x Length in Feet / 16)
  • International 1/4-inch Log Rule: (0.905 x Small End Diameter in Inches²) – (1.65 x Small End Diameter in Inches) – (3.75 x Length in Feet / 12)

  Note: These formulas provide estimates, and actual yield can vary.

• Estimating the Volume of Firewood in Cords:

  • Measure the height, width, and length of the stacked firewood in feet.
  • Multiply the three dimensions together to get the volume in cubic feet.
  • Divide the volume in cubic feet by 128 to get the volume in cords.

• Estimating Drying Time Based on Moisture Content:

  • Drying time depends on several factors, including wood species, climate, and storage conditions.
  • As a general rule, it takes at least 6-12 months for firewood to dry properly.
  • Use a moisture meter to measure the moisture content of the wood. Aim for a moisture content of 20% or less.
