Today, while the tools and techniques have evolved, the fundamental principles remain the same: transforming raw wood into usable material. As someone who has spent countless hours in the woods, felling trees, splitting logs, and milling lumber, I understand the allure and the challenges of wood processing. In this article, I’ll dive into the world of cost and budgeting for wood processing and firewood preparation, drawing on my own experiences and insights.

Stihl Weedeater FS 91 Tips for Wood Processing: A Deep Dive into Cost and Budgeting

The Stihl FS 91 is primarily designed as a string trimmer, but with the right attachments and know-how, it can be surprisingly versatile for small-scale wood processing tasks. While it won’t replace a chainsaw for felling large trees, it can be a valuable tool for clearing brush, preparing firewood, and even light milling applications. However, before you start modifying your FS 91, it’s crucial to understand the costs involved and how to budget effectively.

1. Understanding the Scope: Variables Affecting Project Costs

Before even thinking about starting, I always take a moment to consider the variables that will impact my costs. Just like a seasoned sailor reads the wind, understanding these factors helps me navigate the financial waters of any wood processing project.

• Wood Species: Softwoods like pine are generally cheaper and easier to process than hardwoods like oak or maple.
• Wood Quality: Rot, knots, and other defects can significantly reduce the usable yield and increase processing time.
• Location Accessibility: The ease of access to the wood source will impact transportation costs and labor time. A remote location will require more effort and potentially specialized equipment.
• Seasonality: The time of year affects wood moisture content, drying times, and even labor availability. Winter often brings lower labor rates but harsher working conditions.
• Project Scale: Are you processing a few logs for a small woodworking project or preparing cords of firewood for the winter? The scale directly impacts equipment needs, labor requirements, and overall costs.

2. Breaking Down the Cost Components: A Systematic Approach

To effectively budget, it’s essential to break down the costs into manageable components. This allows me to identify areas where I can potentially save money and ensure I’m not overlooking any expenses.

2.1 Timber Purchase or Harvesting Costs

• Purchasing Timber: If you’re buying timber, the price will depend on the species, grade, and volume. Prices can vary widely based on location and market conditions. I’ve seen timber prices range from \$50 per cord for mixed hardwoods to \$200+ per cord for premium hardwoods like black walnut. The key is to shop around, compare prices, and negotiate when possible.
• Harvesting Your Own Timber: If you’re harvesting your own timber, you’ll need to factor in the cost of permits (if required), equipment (chainsaw, fuel, safety gear), and labor (your time or hired help). Even if you’re not paying yourself an hourly wage, it’s essential to value your time. I typically estimate my time at \$25-\$50 per hour, depending on the complexity of the work.

2.2 Tool Costs: Chainsaw, FS 91 Attachments, and More

• FS 91 Attachments: The Stihl FS 91 can be adapted for various wood processing tasks with attachments. A brush knife attachment is useful for clearing small trees and brush, while a circular saw blade can be used for light milling or cutting small logs. Attachment prices range from \$50 to \$200, depending on the type and quality.
• Chainsaw: While the FS 91 can handle some tasks, a chainsaw is essential for most wood processing projects. The cost of a chainsaw can range from \$200 for a basic homeowner model to \$1000+ for a professional-grade saw. I recommend investing in a quality chainsaw that is appropriate for the size of the trees you’ll be working with.
• Other Tools: Don’t forget about other essential tools like axes, splitting mauls, wedges, measuring tapes, and safety gear (helmet, chaps, gloves, eye protection). These can add up to several hundred dollars.
• Tool Maintenance: Regular maintenance is crucial to keep your tools running smoothly and safely. This includes sharpening chains, cleaning air filters, replacing spark plugs, and lubricating moving parts. I typically budget 10-15% of the tool’s purchase price annually for maintenance.

2.3 Labor Wages: Hiring Help or Valuing Your Time

• Hired Labor: If you’re hiring help, labor costs will depend on the skill level and experience of the workers. General labor rates typically range from \$15 to \$30 per hour, while skilled chainsaw operators or millwrights may charge \$30 to \$50+ per hour.
• Valuing Your Time: Even if you’re doing the work yourself, it’s important to value your time. Consider what you could be earning doing other tasks and factor that into your budget. This will help you make informed decisions about whether to hire help or tackle the project yourself.

2.4 Permits and Regulations: Navigating the Red Tape

• Harvesting Permits: In many areas, you’ll need a permit to harvest timber, even on your own property. Permit fees can vary widely depending on the location and the volume of timber being harvested.
• Environmental Regulations: Be aware of any environmental regulations that may apply to your project. These regulations may restrict the types of trees you can harvest, the time of year you can harvest, or the methods you can use.
• Local Ordinances: Check with your local government to see if there are any ordinances that regulate wood processing activities. These ordinances may restrict noise levels, hours of operation, or the storage of firewood.

2.5 Transportation Costs: Getting the Wood Where it Needs to Be

• Fuel Costs: Transporting logs or firewood can be a significant expense, especially if you’re hauling them long distances. Fuel costs will depend on the type of vehicle you’re using, the distance you’re traveling, and the current price of fuel.
• Vehicle Maintenance: Hauling heavy loads can put a strain on your vehicle, so be sure to factor in the cost of maintenance and repairs.
• Rental Equipment: If you don’t have a truck or trailer, you may need to rent one. Rental rates can vary depending on the type of equipment and the rental period.

2.6 Drying and Storage Costs: Preparing for the Long Haul

• Drying Time: Proper drying is essential for preventing wood from warping, cracking, or rotting. Drying times can vary depending on the species of wood, the climate, and the drying method. Air-drying typically takes several months to a year, while kiln-drying can take as little as a few days.
• Storage Space: You’ll need a dry, well-ventilated space to store your wood while it’s drying. This could be a shed, a barn, or simply a covered area in your yard.
• Storage Costs: If you’re renting storage space, you’ll need to factor in the cost of rent. Even if you’re using your own property, there may be costs associated with maintaining the storage area.

3. Data-Backed Content: Industry Benchmarks and Statistical Data

To provide a realistic picture of wood processing costs, it’s essential to look at industry benchmarks and statistical data.

    18. The Versatile FS 91: Beyond the Weeds

    While primarily a string trimmer, the Stihl FS 91, when paired with the right attachments, can be a useful ally in certain wood processing tasks. Here are some specific “pro hacks” you can employ, remembering that safety and appropriate usage are paramount:

    • Brush Clearing Powerhouse: The brush knife attachment transforms the FS 91 into a formidable tool for clearing undergrowth, small saplings (up to 2-3 inches in diameter, depending on the wood species), and dense vegetation. This is invaluable for preparing a worksite before felling larger trees or for creating access paths in wooded areas. Cost consideration: While the attachment itself is relatively inexpensive (around \$75-\$150), factor in the cost of replacement blades and the time saved compared to manual clearing. Manual clearing can easily take 2-3 times longer, translating to significant labor cost savings.
    • Precision Pruning and Limb Removal: Using a pruning saw attachment, the FS 91 becomes a precise tool for removing small branches and limbs from felled trees. This is particularly useful for preparing logs for milling or firewood processing. Cost consideration: The pruning saw attachment offers greater control and precision than a chainsaw for smaller limbs, reducing the risk of kickback and improving the overall quality of the wood. The cost savings come from reduced material waste and improved efficiency.
    • Firewood Kindling Creation: While not ideal for splitting large logs, the FS 91 with a circular saw blade attachment can be used to create kindling from small branches and scraps. Cost consideration: This is a great way to utilize waste wood and avoid the need to purchase kindling. However, always exercise extreme caution when using a circular saw blade attachment and wear appropriate safety gear.
    • Debarking Aid (with caution): With a specialized debarking tool attachment (less common but available), the FS 91 can assist in removing bark from logs. Cost Consideration: Debarking can speed up drying times and reduce the risk of insect infestation. However, this application is demanding on the tool and requires careful technique to avoid damaging the wood. The cost saving is in reduced drying time and potential wood loss from insect damage.
    • Small Diameter Log Cutting (with extreme caution): With a carbide-tipped circular saw blade (specifically designed for wood cutting), the FS 91 can be used to cut small diameter logs (up to 4-5 inches, depending on the blade and wood density). Cost Consideration: This is the most dangerous application and should only be attempted by experienced users with appropriate safety gear. The primary benefit is portability – the FS 91 is much lighter and easier to maneuver than a chainsaw. However, the risk of kickback and injury is significantly higher. It is generally better to use a proper chainsaw. I would only recommend this if you are cutting small logs in an extremely remote location where carrying a chainsaw is impractical.

    Important Note: Always consult the Stihl FS 91 user manual and follow all safety guidelines when using attachments. Never exceed the tool’s recommended capacity.
