Stihl MS 250 Chain Size Guide (5 Expert Tips for Optimal Cutting)

Introduction: Riding the Wood Processing Wave – Smart Cuts and Smart Budgets

I’ve been around wood my whole life, from helping my grandfather stack firewood as a kid to now managing my own small-scale wood processing operation. I’ve seen firsthand how the right equipment and a solid understanding of costs can make all the difference between a profitable venture and a costly hobby. The rising costs of energy and the renewed interest in sustainable heating have created a surge in demand for firewood and processed wood. This, in turn, has driven up the prices of timber, equipment, and even labor. But with careful planning and a keen eye on expenses, you can navigate this market successfully.

Understanding the Stihl MS 250 Chain: Size Matters (and So Does Your Wallet)

The Stihl MS 250 is a popular choice for homeowners and light-duty professionals because it strikes a good balance between power and portability. However, maximizing its performance requires using the correct chain.

• Standard Chain Sizes: The Stihl MS 250 typically uses a 16-inch or 18-inch bar, which corresponds to specific chain lengths. The number of drive links will vary depending on the bar length. For a 16-inch bar, you’ll generally need a chain with 55 drive links, while an 18-inch bar requires 61 drive links. It’s crucial to check your bar’s stamped information for the exact number.
• Chain Pitch and Gauge: The MS 250 commonly uses a .325″ pitch chain with a .050″ gauge. The pitch is the distance between three rivets divided by two, and the gauge is the thickness of the drive links that fit into the bar groove. Using the wrong pitch or gauge can damage your chainsaw and create unsafe cutting conditions.
• Chain Types: You have options like full chisel, semi-chisel, and low-kickback chains. Full chisel chains are aggressive cutters ideal for clean wood but dull quickly in dirty conditions. Semi-chisel chains are more forgiving and hold their edge longer, making them a good all-around choice. Low-kickback chains are designed for safety and are recommended for inexperienced users.

Cost Considerations: The price of a replacement chain for the MS 250 ranges from $20 to $40, depending on the brand, type, and retailer. I’ve found that buying chains in bulk online can save you money in the long run, especially if you’re processing a lot of wood.

5 Expert Tips for Optimal Cutting (and Minimal Waste)

1. Sharpness is Key: A dull chain not only cuts poorly but also puts unnecessary strain on your chainsaw and increases fuel consumption. Sharpen your chain regularly using a file or a chain grinder. I personally prefer using a file in the field because it allows me to maintain the chain’s edge between major sharpening sessions.
   • Cost of Sharpening: A chainsaw file kit costs around $20-$30. If you prefer using a professional sharpening service, expect to pay $10-$15 per chain.
2. Proper Chain Tension: A properly tensioned chain should be snug against the bar but still able to be pulled around by hand. Too loose, and it can derail; too tight, and it can overheat and wear prematurely.
3. Lubrication is Essential: Use a high-quality bar and chain oil to keep the chain lubricated and reduce friction. Check the oil level frequently and refill as needed.
   • Cost of Bar and Chain Oil: A gallon of bar and chain oil typically costs between $15 and $25. I’ve found that using a good quality oil can extend the life of your chain and bar.
4. Cutting Techniques: Use proper cutting techniques to avoid kickback and other hazards. Always maintain a firm grip on the chainsaw and keep both feet firmly planted on the ground.
5. Clean Your Saw Regularly: Sawdust and debris can accumulate in the chainsaw’s components, causing it to overheat and malfunction. Clean your saw regularly with compressed air or a brush.

The Real Cost of Firewood: Breaking Down the Expenses

Now, let’s get down to the nitty-gritty: the cost of producing firewood. This is where my experience really comes into play. I’ve learned that careful budgeting and cost control are essential for making a profit in the firewood business.

• Timber Costs: The cost of timber varies widely depending on the species, quality, and location. In some areas, you can obtain free firewood by clearing dead or fallen trees on your property or with permits from local authorities. However, if you need to purchase timber, you’ll need to factor in the cost per cord or board foot. According to the US Forest Service, the average stumpage price (the price paid for standing timber) for hardwood sawtimber in the Eastern United States ranges from $50 to $200 per thousand board feet. Firewood prices per cord ranged from $120 to $400 depending on wood species and location in 2023.
• Harvesting Costs: If you’re harvesting your own timber, you’ll need to factor in the cost of your chainsaw, fuel, bar and chain oil, and safety equipment. You’ll also need to consider the time it takes to fell the trees, limb them, and buck them into firewood lengths.
  • Chainsaw Costs: As mentioned earlier, the Stihl MS 250 is a good option for homeowners and light-duty professionals. However, if you’re processing a lot of wood, you may want to consider a more powerful chainsaw. The cost of a professional-grade chainsaw can range from $500 to $1000 or more.
  • Fuel Costs: Chainsaws typically consume about 1 gallon of fuel per day of heavy use. At a price of $4 per gallon, that’s $4 per day.
  • Safety Equipment: Safety equipment, including a helmet, chaps, gloves, and eye protection, is essential for safe chainsaw operation. The cost of a complete set of safety equipment can range from $100 to $200.
• Processing Costs: Once you’ve harvested the timber, you’ll need to process it into firewood. This typically involves splitting the wood and stacking it to dry.
  • Splitting Costs: You can split wood manually with a maul and wedge, or you can use a log splitter. Manual splitting is a good option for small quantities of wood, but it can be physically demanding. A log splitter can significantly speed up the process, but it’s a significant investment.
    • Manual Splitting: A good quality maul and wedge set costs around $50-$100.
    • Log Splitter: A gas-powered log splitter can range from $1000 to $3000 or more. Electric log splitters are also available and are typically less expensive. Rental options for log splitters are also available, costing approximately $75-$150 per day.
  • Stacking Costs: Stacking firewood is a labor-intensive task. If you’re paying someone to stack your firewood, you’ll need to factor in their hourly wage.
• Drying Costs: Firewood needs to be dried before it can be burned efficiently. The drying process can take several months or even a year, depending on the species of wood and the climate.
  • Storage Costs: You’ll need a place to store your firewood while it’s drying. This could be a simple woodpile in your backyard, or it could be a more elaborate woodshed.
  • Time is Money: Remember that the longer it takes to dry your firewood, the longer it takes to sell it and recoup your investment.
• Delivery Costs: If you’re selling firewood, you’ll need to factor in the cost of delivering it to your customers. This could involve using your own truck or hiring a delivery service.
  • Truck Costs: If you’re using your own truck, you’ll need to factor in the cost of fuel, maintenance, and insurance.
  • Delivery Service: Hiring a delivery service can be a good option if you don’t have your own truck or if you’re delivering firewood to a large area.

Data-Driven Insights: Timber Prices, Equipment Rentals, and Fuelwood Market Rates

To give you a clearer picture of the costs involved, here’s some data from various sources:

• Timber Prices: According to the Timber Mart-South, a leading timber price reporting service, the average price for hardwood pulpwood in the Southern United States was around $20 per ton in 2023. This price can vary depending on the species, quality, and location.
• Equipment Rental Fees: According to Sunbelt Rentals, a national equipment rental company, the daily rental rate for a gas-powered log splitter ranges from $75 to $150, depending on the size and power of the splitter.
• Fuelwood Market Rates: According to the Energy Information Administration (EIA), the average price of residential firewood in the United States was around $250 per cord in 2023. This price can vary depending on the species of wood, the location, and the time of year.

Original Research: Budgeting Case Study – My Own Firewood Project

To illustrate how these costs can add up, let’s look at a case study based on my own firewood project. Last year, I harvested and processed 10 cords of firewood from my property. Here’s a breakdown of my costs:

• Timber Costs: $0 (I harvested the timber from my property)
• Chainsaw Costs: $50 (Fuel, bar and chain oil, and maintenance for my Stihl MS 250)
• Safety Equipment: $0 (I already owned the necessary safety equipment)
• Splitting Costs: $0 (I split the wood manually with a maul and wedge)
• Stacking Costs: $100 (I paid a neighbor $10 per cord to help me stack the wood)
• Drying Costs: $0 (I stored the firewood in my backyard)
• Delivery Costs: $50 (Fuel and maintenance for my truck)

Total Costs: $200

I sold the 10 cords of firewood for $250 per cord, generating a revenue of $2500.

Profit: $2300

This case study demonstrates that it’s possible to make a profit from processing firewood, even on a small scale. However, it’s important to carefully track your costs and price your firewood accordingly.

Practical Tips for Cost Optimization and Budget Management

Here are some practical tips for optimizing your costs and managing your budget in wood processing or firewood preparation projects:

• Source Your Timber Wisely: Look for free or low-cost sources of timber, such as dead or fallen trees on your property or with permits from local authorities.
• Maintain Your Equipment: Regularly maintain your chainsaw and other equipment to prevent costly repairs.
• Sharpen Your Chain Regularly: A sharp chain will cut more efficiently and reduce fuel consumption.
• Split Wood Manually: If you’re only processing a small amount of wood, consider splitting it manually with a maul and wedge to avoid the cost of renting or purchasing a log splitter.
• Dry Your Firewood Properly: Properly dried firewood will burn more efficiently and generate more heat.
• Price Your Firewood Competitively: Research the market rates for firewood in your area and price your firewood accordingly.
• Track Your Costs: Keep track of all your costs, including timber, equipment, fuel, labor, and delivery. This will help you identify areas where you can reduce your expenses.

Calculations and Formulas: Estimating Volume and Drying Time

Here are some relevant calculations and formulas that can help you estimate the volume of logs and the drying time of firewood:

• Board Feet: A board foot is a unit of measurement for lumber that is 1 inch thick, 12 inches wide, and 12 inches long. The formula for calculating the board feet in a log is:

  Board Feet = (Diameter in inches - 4) * (Length in feet / 16)

  This formula is a simplified version of the Doyle Log Scale, a common method for estimating the board feet in a log. * Cords: A cord is a unit of measurement for firewood that is 4 feet high, 4 feet wide, and 8 feet long. A cord contains 128 cubic feet of wood, including air space. * Drying Time: The drying time of firewood depends on several factors, including the species of wood, the climate, and the size of the pieces. As a general rule, hardwoods take longer to dry than softwoods. You can estimate the drying time of firewood using the following guidelines:

  • Softwoods: 6-9 months
  • Hardwoods: 12-18 months

  These are just estimates, and the actual drying time may vary depending on the specific conditions.
