The acquisition by Makita, the shift towards battery power, it all felt like the end of an era.

But even as we reminisced about the legendary two-stroke engines, we understood that progress is inevitable. Still, the lessons learned from decades of working with wood, fueled by that distinctive Dolmar hum, remain timeless.

So, grab your axe, sharpen your saw (metaphorically, for now), and let’s delve into the world of Dolmar chainsaws, the changing landscape of the industry, and, most importantly, five must-know tips to help you master the art of wood processing and firewood preparation, all while keeping a close eye on your budget.

Dolmar Chainsaws: Gas Power Ended? (5 Must-Know Wood Tips)

The acquisition of Dolmar by Makita marked a significant shift in the chainsaw industry. While Dolmar gas-powered saws were renowned for their power and reliability, the move towards battery-powered alternatives reflects a broader trend towards sustainability and reduced emissions. Whether this truly signals the “end” of gas power remains to be seen, but it undeniably marks a turning point. This article explores the legacy of Dolmar gas chainsaws, the rise of battery-powered options, and, most importantly, how to navigate the world of wood processing and firewood preparation, regardless of your preferred power source.

1. Understanding Your Wood: Species, Quality, and Cost Implications

The single most important factor influencing the cost of your wood processing project is the wood itself. It’s not just about grabbing the cheapest pile you can find. Understanding the species, quality, and moisture content will significantly impact your labor, tool wear, and ultimately, the value you get from your firewood or lumber.

• Species Matters: Different species have vastly different densities, burning characteristics (if you’re dealing with firewood), and working properties. Hardwoods like oak, maple, and beech are denser, burn longer, and produce more heat than softwoods like pine, fir, and spruce. However, hardwoods are also harder to split and can dull your chainsaw blade faster.
  • Example: A cord of seasoned oak might cost twice as much as a cord of seasoned pine in some regions. But the oak will provide significantly more heat and burn for a longer period, making it a better long-term investment.
  • Data Point: According to the U.S. Energy Information Administration (EIA), the average heat content of hardwoods is approximately 20 million BTU per cord, while softwoods average around 15 million BTU per cord.
• Quality Counts: The quality of the wood, specifically the presence of knots, rot, and insect damage, will affect how easy it is to process and how much usable material you get. Avoid wood that is excessively knotty or shows signs of decay.
  • Personal Experience: I once bought a “bargain” load of firewood that turned out to be riddled with rot. I ended up throwing away nearly half of it, making it a very expensive lesson in quality control.
• Moisture Content is Key: For firewood, moisture content is critical. Green wood is difficult to burn and produces creosote, a flammable substance that can build up in your chimney and pose a fire hazard. Seasoned wood, with a moisture content of 20% or less, burns cleanly and efficiently.
  • Rule of Thumb: It generally takes 6-12 months to properly season firewood, depending on the species, climate, and how it’s stacked.
  • Cost Implication: Green wood is often cheaper than seasoned wood, but you’ll need to factor in the time and effort required to season it yourself. You’ll also need a moisture meter (cost: $20-$50) to accurately assess the moisture content.
• Timber Prices Globally: Timber prices vary significantly worldwide, influenced by factors like species, location, demand, and harvesting regulations. For example, in Scandinavia, where forestry is a major industry, timber prices are generally competitive due to well-managed forests and efficient harvesting practices. In contrast, regions with limited forest resources or stricter environmental regulations may have higher timber prices. Keep in mind that transport costs can also heavily influence the final price of timber.

  • Case Study: I switched from a gas-powered Dolmar to a battery-powered saw for limbing and smaller firewood tasks. While the initial investment was higher, I’ve saved money on fuel and maintenance in the long run, and the convenience of not having to mix gas is a definite plus.
• Chainsaw Size and Power: Choose a saw that is appropriate for the size of the wood you’ll be cutting. A small saw will struggle with large logs, while a large saw can be unwieldy for smaller tasks.
  • General Guidelines:
    • Small Limbs and Branches: 14-16 inch bar
    • Firewood (Small to Medium Logs): 16-18 inch bar
    • Large Logs (Felling Trees): 20+ inch bar
• Chain Sharpening: A sharp chain is essential for efficient cutting and safety. A dull chain will require more effort, increase the risk of kickback, and put unnecessary strain on your saw.
  • Cost of Sharpening: $10-$20 per sharpening (professionally) or $20-$50 for a chain sharpening kit (DIY).
  • Expert Tip: Learn to sharpen your own chain. It’s a valuable skill that will save you time and money in the long run.
• Bar Oil: Use high-quality bar oil to lubricate the chain and bar. This will reduce friction, prevent overheating, and extend the life of your saw.
  • Cost of Bar Oil: $10-$20 per gallon.

Actionable Takeaway: Carefully consider your needs and budget when choosing a chainsaw. Factor in the long-term costs of fuel, maintenance, and battery replacement. A well-maintained saw will not only save you money but also improve your safety and efficiency.

3. Mastering Splitting Techniques: Manual vs. Powered

Splitting wood is often the most physically demanding part of firewood preparation. Choosing the right splitting technique and tools can significantly reduce your labor and improve your efficiency.

• Manual Splitting:
  • Axe: A good splitting axe is essential for manual splitting. Choose an axe that is the right weight and length for your strength and experience.
    • Cost of Splitting Axe: $50 – $150
  • Splitting Maul: A splitting maul is heavier than an axe and is designed for splitting larger, more difficult logs.
    • Cost of Splitting Maul: $75 – $200
  • Wedges: Wedges can be used to split particularly tough logs that resist the axe or maul.
    • Cost of Wedges: $20 – $50 per set
  • Technique is Key: Proper technique is crucial for safe and efficient manual splitting. Keep your back straight, use your legs and core muscles, and aim for the natural grain of the wood.
• Powered Splitting:
  • Hydraulic Log Splitter: A hydraulic log splitter can significantly reduce the effort required to split wood, especially large or knotty logs.
    • Cost of Hydraulic Log Splitter: $1000 – $3000+ (depending on size and power)
    • Rental Fees: $50-$100 per day (a viable option for occasional use)
  • Electric Log Splitter: Electric log splitters are quieter and more environmentally friendly than gas-powered models.
    • Cost of Electric Log Splitter: $500 – $1500
  • Cost-Benefit Analysis: Consider the amount of wood you need to split each year. If you only split a few cords, manual splitting may be the most cost-effective option. However, if you split a large amount of wood, a hydraulic log splitter can save you significant time and effort.
• Labor Costs: If you are hiring someone to split wood for you, labor costs can be a significant expense.
  • Average Labor Rate: $20-$40 per hour (depending on location and experience).

Cost Example: Splitting 5 Cords of Wood

Actionable Takeaway: Evaluate the amount of wood you need to split and your physical capabilities. Consider renting a log splitter if you only need it occasionally. Invest in quality tools and learn proper techniques to minimize your effort and risk of injury.

4. Drying and Storage: Maximizing Efficiency and Minimizing Waste

Proper drying and storage are essential for maximizing the efficiency and minimizing the waste of your firewood.

• Seasoning Time: As mentioned earlier, green wood is difficult to burn and produces creosote. Seasoning wood involves allowing it to air dry until its moisture content is below 20%.
  • Factors Affecting Seasoning Time:
    • Species: Hardwoods generally take longer to season than softwoods.
    • Climate: Warm, dry climates promote faster seasoning.
    • Stacking Method: Properly stacking wood allows for good air circulation, which speeds up the drying process.
• Stacking Techniques: Stack wood in a single row, off the ground, and with gaps between the pieces. This will allow for maximum air circulation. Cover the top of the stack to protect it from rain and snow.
  • Materials Costs: Pallets (free or $5-$10 each), tarps ($20-$50).
• Storage Location: Choose a storage location that is well-ventilated and protected from the elements. Avoid storing wood directly on the ground or in damp areas.
• Moisture Meter: Use a moisture meter to accurately measure the moisture content of your wood. This will help you determine when it is properly seasoned.
• Minimizing Waste: Proper drying and storage will prevent wood from rotting or becoming infested with insects. This will ensure that you get the most value from your firewood.

Formula for Estimating Drying Time:

While it’s impossible to give an exact timeline, you can estimate drying time based on these factors:

• Drying Time (Months) ≈ (Initial Moisture Content – Target Moisture Content) / Drying Rate

  • Initial Moisture Content: The moisture content of the wood when freshly cut (typically 40-60%).
  • Target Moisture Content: The desired moisture content for burning (below 20%).
  • Drying Rate: The rate at which the wood loses moisture, which depends on the climate, species, and stacking method (typically 1-3% per month).

Example:

• Initial Moisture Content: 50%
• Target Moisture Content: 20%

• Drying Rate: 2% per month

  • Drying Time ≈ (50 – 20) / 2 = 15 months

Actionable Takeaway: Invest the time and effort to properly dry and store your firewood. This will improve its burning efficiency, reduce creosote buildup, and minimize waste.

5. Budgeting and Cost Optimization: Making the Most of Your Resources

Effective budgeting and cost optimization are essential for managing your wood processing and firewood preparation projects.

• Create a Detailed Budget: Start by creating a detailed budget that includes all of the costs associated with your project, including:
  • Wood Purchase: Cost of raw wood (logs, standing timber, or pre-cut firewood).
  • Tool Costs: Chainsaw, axe, splitting maul, wedges, log splitter (purchase or rental).
  • Maintenance Costs: Fuel, bar oil, chain sharpening, repairs.
  • Labor Costs: Wages for hired help (if applicable).
  • Transportation Costs: Fuel for hauling wood.
  • Permit Costs: If you’re harvesting timber from public lands, you may need a permit.
• Compare Prices: Shop around for the best prices on wood, tools, and supplies.
• Consider Used Equipment: Buying used equipment can save you money, but be sure to inspect it carefully before you buy.
• DIY vs. Hiring: Evaluate whether it is more cost-effective to do the work yourself or hire someone to do it for you.
• Optimize Your Process: Look for ways to improve your efficiency and reduce waste. For example, properly stacking wood will speed up the drying process and reduce the risk of rot.
• Track Your Expenses: Keep track of your expenses so you can see where your money is going and identify areas where you can save.
