- Fuel Tank Capacity: 0.56 l / 18.9 oz
- Oil Tank Capacity: 0.28 l / 9.5 oz
- Recommended Bar Length: 16″ – 20″
These specifications provide a foundation for understanding the chainsaw’s capabilities. However, the recommended bar length is just that – a recommendation. Modifying it can tailor the saw to specific needs, but it’s essential to proceed with caution and knowledge.
Understanding Bar Length and Its Impact
The bar length of a chainsaw dictates the size of the wood it can efficiently cut. A longer bar allows for felling larger trees and processing bigger logs in a single pass, while a shorter bar offers increased maneuverability and control for limbing and smaller tasks.
Choosing the right bar length is a balancing act. A bar that is too long for the engine can strain the saw, reducing its lifespan and cutting efficiency. Conversely, a bar that is too short can limit the saw’s versatility.
5 Pro Tips for Bar Length Modifications on the Stihl 310
Here are five pro tips to consider when modifying the bar length of your Stihl 310:
1. Consider Your Primary Use
What will you primarily be using the chainsaw for? Felling large trees? Clearing brush? Cutting firewood? The answer will heavily influence the ideal bar length.
- Felling Large Trees: If you regularly fell trees with a diameter exceeding 20 inches, a longer bar (20 inches) might be beneficial.
- Firewood Processing: For firewood, a shorter bar (16 inches) offers better control and maneuverability, especially when bucking smaller logs.
- General Purpose: A 18-inch bar offers a good compromise for a variety of tasks.
2. Evaluate Engine Power and Torque
The Stihl 310 boasts a respectable 3.1 kW of power, but it’s crucial to consider this in relation to the bar length. Overloading the engine with a bar that is too long will significantly reduce its performance and potentially damage it.
- Longer Bar = More Resistance: A longer bar requires more power to pull the chain through the wood.
- Listen to Your Saw: If the saw bogs down or struggles to maintain RPMs, the bar might be too long.
3. Check Chain Pitch and Gauge Compatibility
The chain pitch and gauge must match the sprocket and bar. Using an incompatible chain can damage the saw and create a safety hazard. The Stihl 310 typically uses a .325″ pitch chain with a .063″ gauge. Always verify compatibility before making any changes.
- Pitch: The distance between three consecutive rivets divided by two.
- Gauge: The thickness of the drive links that fit into the bar groove.
4. Adjust Chain Tension Properly
Proper chain tension is crucial for safe and efficient operation, regardless of the bar length. A loose chain can derail, while a tight chain can overheat and break. Check the chain tension regularly and adjust as needed.
- Ideal Tension: The chain should be snug against the bar but still able to be pulled around by hand.
- New Chains Stretch: New chains will stretch during the first few uses, requiring frequent adjustments.
5. Upgrade the Sprocket (Optional)
For significant bar length modifications, consider upgrading the sprocket. A different sprocket ratio can optimize the saw’s performance for the new bar length. This is especially relevant when moving to a significantly longer or shorter bar.
- Smaller Sprocket: Can provide more torque for longer bars.
- Larger Sprocket: Can increase chain speed for shorter bars.
The Economics of Wood Processing and Firewood Preparation
Now, let’s shift our focus to the financial aspects of wood processing and firewood preparation. I’ve been involved in firewood production for over 15 years, and I can tell you firsthand that understanding the costs involved is crucial for profitability, whether you’re a small-scale operator or a homeowner looking to save money on heating.
Variable Factors Affecting Project Costs
Several factors influence the overall cost of wood processing and firewood preparation. These include:
- Wood Species: Hardwoods like oak and maple are denser and require more effort to cut and split than softwoods like pine and fir. They also command a higher price in the firewood market.
- Wood Quality: Rotten or diseased wood is difficult to process and has little value as firewood.
- Location and Accessibility: The distance to the wood source and the ease of access significantly impact transportation costs.
- Seasonality: Wood prices tend to fluctuate with demand, typically peaking during the colder months.
- Labor Costs: Whether you’re paying a logging crew or doing the work yourself, labor is a significant cost factor.
- Equipment Costs: Chainsaws, splitters, trailers, and other equipment represent a substantial investment.
Breaking Down the Cost Components
To effectively budget for wood processing and firewood preparation, it’s essential to break down the cost components systematically:
1. Timber Purchase or Harvesting Costs
If you’re purchasing timber, the cost will vary depending on the species, quality, and location. Prices are typically quoted per board foot, cord, or ton.
- Board Foot: A unit of volume equal to 144 cubic inches (12″ x 12″ x 1″).
- Cord: A unit of volume equal to 128 cubic feet (typically a stack of wood 4′ x 4′ x 8′).
- Ton: A unit of weight equal to 2,000 pounds.
According to recent data, the average price for standing timber (the price paid to the landowner for the right to harvest trees) in the United States ranges from $20 to $50 per ton for softwoods and $50 to $100 per ton for hardwoods. However, these prices can vary significantly depending on regional market conditions.
If you’re harvesting timber from your own property, you’ll still incur costs associated with felling, skidding, and loading the logs. These costs can range from $5 to $20 per ton, depending on the terrain and equipment used.
2. Tool Costs: Chainsaws, Splitters, and More
The cost of equipment is a significant investment. Chainsaws, splitters, trailers, and safety gear can quickly add up.
- Chainsaw: A quality chainsaw like the Stihl 310 can cost between $400 and $600.
- Log Splitter: A hydraulic log splitter can range from $1,000 to $5,000, depending on the size and power.
- Trailer: A utility trailer for hauling logs and firewood can cost between $1,000 and $3,000.
- Safety Gear: Helmet, chaps, gloves, and eye protection can cost between $200 and $400.
In addition to the initial purchase price, you’ll also need to factor in maintenance costs, such as fuel, oil, chain sharpening, and repairs. I typically budget around 10% of the equipment’s purchase price annually for maintenance.
3. Labor Wages
If you’re hiring a logging crew or firewood handlers, labor costs will be a significant expense. Wages vary depending on the region and the skill level of the workers.
According to the Bureau of Labor Statistics, the median hourly wage for logging workers in the United States was $20.19 in May 2022. However, wages can be higher in areas with a high cost of living or a shortage of skilled workers.
When calculating labor costs, be sure to include not only wages but also payroll taxes, workers’ compensation insurance, and any benefits you provide. These additional costs can add 20-30% to the base wage.
4. Permits and Fees
Depending on your location and the scale of your operation, you may need to obtain permits for harvesting timber or selling firewood. These permits can cost anywhere from a few dollars to several hundred dollars, depending on the regulations in your area.
Be sure to research the permit requirements in your area and factor these costs into your budget.
5. Transportation Costs
Transportation costs can be a significant expense, especially if you’re hauling logs or firewood over long distances. These costs include fuel, vehicle maintenance, and driver wages (if applicable).
Fuel costs are particularly volatile, so it’s essential to track fuel prices closely and adjust your budget accordingly. I use a fuel cost calculator to estimate my fuel expenses based on the distance traveled and the fuel efficiency of my vehicles.
6. Drying and Storage Costs
Firewood needs to be properly dried before it can be burned efficiently. This typically involves stacking the wood in a well-ventilated area for six to twelve months.
If you’re selling firewood, you’ll also need to factor in the cost of storing the wood. This may involve renting a storage yard or building a shed.
Current Industry Benchmarks and Statistical Data
To provide a better understanding of the costs involved, here are some current industry benchmarks and statistical data:
- Average Price per Cord of Firewood: The average price for a cord of firewood in the United States ranges from $200 to $400, depending on the species, quality, and location. Prices tend to be higher in urban areas and during the winter months.
- Average Cost to Produce a Cord of Firewood: The average cost to produce a cord of firewood ranges from $100 to $200, depending on the factors mentioned above.
- Average Profit Margin for Firewood Sales: The average profit margin for firewood sales ranges from 10% to 30%, depending on the efficiency of your operation and the prices you can command in the market.
These benchmarks provide a starting point for estimating your own costs and profitability. However, it’s essential to conduct your own research and tailor your budget to your specific circumstances.
Practical Tips for Cost Optimization and Budget Management
Here are some practical tips for cost optimization and budget management in wood processing and firewood preparation projects:
- Negotiate Timber Prices: Don’t be afraid to negotiate timber prices with landowners. You may be able to get a better deal if you’re willing to harvest a larger volume of timber or if you’re willing to take on more of the harvesting responsibilities.

Relevant Calculations and Formulas
Here are some relevant calculations and formulas that can be helpful in budgeting for wood processing and firewood preparation:
-
Estimating Volume of Logs in Board Feet:
- Doyle Log Rule: (Diameter – 4)^2 * Length / 16 (This rule tends to underestimate the volume of smaller logs)
- Scribner Log Rule: (Diameter – 4)^2 * Length / 20 (This rule is more accurate for larger logs)
- International 1/4-inch Log Rule: This rule is considered the most accurate, but it requires specialized tables or software.
-
Estimating Volume of Firewood in Cords:
-
Measure the length, width, and height of the stack of 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:
-
The drying time for firewood depends on several factors, including the species of wood, the size of the pieces, the climate, and the stacking method.
- Generally, hardwoods take longer to dry than softwoods.
- As a rule of thumb, firewood should be dried for at least six months, and preferably for a year, before burning.
- You can use a moisture meter to check the moisture content of the wood. Firewood should have a moisture content of 20% or less for optimal burning.
