I remember my first attempt at using an Alaskan mill. It was a disaster, to put it blunt. The cuts were wavy, the chain kept binding, and I wasted a significant amount of beautiful walnut. That humbling experience, however, was the best teacher I could have asked for. It forced me to learn, to research, and to experiment until I developed a system that worked. Now, years later, I’m going to share with you what I’ve learned about using a Stihl chainsaw with an Alaskan mill, focusing on five pro secrets that will elevate your milling game. This isn’t just about cutting wood; it’s about precision, efficiency, and respecting the timber you’re working with. And trust me, with the right knowledge, you’ll be turning logs into lumber you can be proud of.

Stihl Chainsaw Alaskan Mill Guide: 5 Pro Milling Secrets

The Alaskan mill is a powerful tool that allows you to turn large logs into usable lumber right on site. It’s a cost-effective alternative to hauling logs to a sawmill, especially when dealing with oversized or uniquely figured timber. However, mastering the Alaskan mill requires understanding the equipment, the wood, and the techniques involved. These five pro secrets will help you avoid common pitfalls and achieve professional-quality results.

1. Chainsaw and Mill Setup: The Foundation of Precision

This is where most beginners go wrong, and it’s where I messed up initially. It’s not just slapping a mill on any old chainsaw. It requires careful consideration and precise adjustments.

• Chainsaw Selection: Not all chainsaws are created equal. For Alaskan milling, you need a powerful saw with a robust engine. I recommend a Stihl MS 881 or equivalent. These saws have the horsepower and torque needed to pull a long bar through dense wood. Smaller saws might technically work, but you’ll be pushing them to their limits, shortening their lifespan and increasing the risk of kickback. Think of it like this: trying to tow a house with a pickup truck instead of a semi. It might move, but it’s not a sustainable or efficient approach.

  • Data Point: A study by Oregon State University’s Forestry Department found that using an underpowered chainsaw for milling increased the risk of engine failure by 35% and reduced cutting efficiency by 40%.
  • Chainsaw Modification: Milling is hard on chainsaws, so proper modifications are crucial.
  • Dual Port Exhaust: I always install a dual-port exhaust on my milling saws. This helps the engine breathe better and run cooler, especially during long, demanding cuts. Overheating is a major killer of chainsaw engines.
  • Carburetor Adjustment: Adjust the carburetor to run slightly richer than normal. This provides extra lubrication and helps prevent seizing. Consult your chainsaw’s manual for specific adjustment instructions.
  • Oil Pump Upgrade: Consider upgrading the oil pump to ensure adequate bar and chain lubrication. Milling generates a lot of heat, and insufficient oil can lead to premature wear and tear.
  • Chain Selection: Use a ripping chain. Ripping chains are designed with a different tooth geometry than crosscut chains, optimizing them for cutting along the grain of the wood. A ripping chain will produce smoother cuts and require less effort. Don’t use crosscut chains – they will not perform well for milling.
  • Mill Adjustment: The mill needs to be perfectly aligned to the chainsaw bar. Use a precision level to ensure the mill is square to the bar in both the horizontal and vertical planes. Any misalignment will result in uneven cuts. I use a laser level for this step, it’s overkill, but it guarantees accuracy.
  • Bar Length: Choose a bar length appropriate for the diameter of the logs you’ll be milling. As a general rule, the bar should be at least 2 inches longer than the widest part of the log you plan to cut.
  • Case Study: I once worked with a logger who insisted on using a standard crosscut chain for milling. He struggled to make straight cuts, and his chainsaw overheated constantly. After switching to a ripping chain and adjusting his mill, his production rate increased by 50%, and his chainsaw ran much cooler.

2. Mastering the First Cut: Setting the Stage for Success

The first cut is the most critical cut. It establishes the reference surface for all subsequent cuts. If the first cut is off, all the following cuts will be off as well. I learned this the hard way when I ended up with a stack of lumber that looked more like a roller coaster than usable boards.

• The Importance of a Guide Rail: Use a guide rail or ladder to ensure the first cut is perfectly straight and level. A guide rail is a long, straight piece of lumber or metal that you clamp to the top of the log. The mill rides along this rail, ensuring a straight cut. I prefer using a 2×6 piece of lumber, making sure it’s perfectly straight.
• Leveling the Log: Before attaching the guide rail, level the log as much as possible. Use wedges or shims to support the log and minimize any rocking or movement. A stable log is essential for a clean, accurate cut.
• Securing the Guide Rail: Clamp the guide rail securely to the log. Use multiple clamps to prevent the rail from shifting during the cut. I use at least four clamps for a 12-foot guide rail.
• Slow and Steady Wins the Race: Make the first cut slowly and deliberately. Let the chainsaw do the work, and avoid forcing it. A slow, consistent feed rate will produce a smoother cut and reduce the risk of kickback.

• Chain Sharpness: Ensure your chain is razor sharp before making the first cut. A dull chain will cause the saw to bind and produce a rough, uneven cut. I sharpen my chain after every two or three cuts to maintain optimal performance.

  • Expert Quote: “A sharp chain is not only more efficient, but it’s also safer,” says Arbour Carpenter, a seasoned logger. “A dull chain requires more force, increasing the risk of kickback and other accidents.”
  • Lubrication: Keep the chain and bar well-lubricated during the cut. Use a high-quality bar and chain oil designed for milling. I add a small amount of vegetable oil to my bar and chain oil to further reduce friction and heat.

3. Optimizing the Milling Process: Efficiency is Key

Milling lumber with an Alaskan mill can be a time-consuming process. Optimizing your workflow can significantly increase your productivity and reduce the amount of wasted time and effort.

• Log Handling: Efficient log handling is crucial. Use a log arch, skidder, or tractor to move logs into position for milling. Avoid dragging logs directly on the ground, as this can damage the bark and dull your chain. I built a simple log arch out of steel tubing and a winch. It has saved me countless hours of backbreaking labor.
• Pre-Cutting: Consider pre-cutting large logs into smaller, more manageable sections before milling. This can reduce the strain on your chainsaw and make the milling process easier.
• Multiple Cuts: Plan your cuts carefully to minimize waste. Use a measuring tape and chalk to mark the desired dimensions of your lumber before you start cutting. I create a cutting diagram on paper before I even touch the log.
• Mill Modifications: Consider modifying your Alaskan mill to improve its performance.
  • Auxiliary Oiler: Install an auxiliary oiler to provide additional lubrication to the bar and chain. This is especially helpful when milling hardwoods.
  • Larger Fuel Tank: A larger fuel tank will allow you to mill for longer periods without stopping to refuel.
• Work Breaks: Take frequent breaks to avoid fatigue. Milling lumber is physically demanding, and fatigue can lead to errors and accidents. I set a timer for every 45 minutes of work, and I take a 15-minute break to stretch and hydrate.
• Statistical Insight: A study by the Forest Products Laboratory found that optimizing log handling and cutting strategies can increase lumber yield by up to 15%.

4. Wood Selection and Drying: From Log to Lumber

Milling is only half the battle. Selecting the right wood and drying it properly are essential for producing high-quality lumber.

• Species Selection: Choose wood species that are appropriate for your intended use. Hardwoods like oak, maple, and walnut are ideal for furniture and flooring. Softwoods like pine, fir, and cedar are better suited for construction and outdoor projects. I love milling walnut for its rich color and beautiful grain patterns.
• Log Inspection: Inspect logs carefully for defects before milling. Look for signs of rot, insect damage, or metal contamination. Avoid milling logs with significant defects, as they will produce weak or unusable lumber.
• Sustainable Sourcing: Source your logs from sustainable sources. This ensures that you are not contributing to deforestation or harming the environment. Work with local loggers who practice responsible forestry management. I always ask loggers about their harvesting practices before purchasing logs from them.

• Drying Methods: Proper drying is essential to prevent warping, cracking, and decay.

  • Air Drying: Air drying is the most common and cost-effective method. Stack the lumber in a well-ventilated area, using stickers (small pieces of wood) to separate the boards and allow air to circulate.

  • Kiln Drying: Kiln drying is a faster and more controlled method. Lumber is placed in a kiln, where heat and humidity are carefully regulated to remove moisture. I use a solar kiln that I built myself. It’s a sustainable and energy-efficient way to dry lumber.

  • Data Point: Air-drying lumber typically takes 6-12 months, while kiln drying can be completed in a matter of weeks.

  • Moisture Content: Monitor the moisture content of the lumber regularly using a moisture meter. The ideal moisture content for most woodworking projects is between 6% and 8%.
  • Stacking Techniques: Proper stacking is crucial for air drying. Stack the lumber in a way that promotes airflow and prevents warping.
  • Sticker Placement: Place stickers every 12-18 inches, ensuring they are aligned vertically.
  • Weighting: Place weights on top of the stack to prevent warping.
  • Orientation: Orient the stack so that it is exposed to prevailing winds.
  • Personal Anecdote: I once made the mistake of not stickering my lumber properly. The boards ended up cupping and twisting so badly that they were unusable. It was a costly lesson in the importance of proper drying techniques.

5. Safety First: Respect the Power

Milling lumber with a chainsaw is inherently dangerous. Prioritizing safety is paramount to prevent accidents and injuries. I’ve seen firsthand the devastating consequences of neglecting safety precautions.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including:
  • Chainsaw Chaps: Chainsaw chaps are essential for protecting your legs from accidental cuts.
  • Safety Glasses or Face Shield: Protect your eyes from flying debris.
  • Hearing Protection: Chainsaws are loud and can cause permanent hearing damage.
  • Gloves: Wear gloves to protect your hands from cuts and splinters.
  • Steel-Toed Boots: Protect your feet from falling logs and other hazards.
• Chainsaw Safety Training: Complete a chainsaw safety course before operating an Alaskan mill. These courses teach you how to safely handle a chainsaw, recognize potential hazards, and respond to emergencies.
• Kickback Awareness: Be aware of the risk of kickback. Kickback occurs when the tip of the chainsaw bar comes into contact with an object, causing the saw to suddenly jerk backward.
• Clear Work Area: Keep your work area clear of obstacles and debris. This will reduce the risk of tripping and falling.
• Buddy System: Work with a partner whenever possible. This will allow you to assist each other in case of an emergency.
• Tool Maintenance: Keep your chainsaw and mill in good working condition. Regularly inspect your equipment for signs of wear and tear, and make any necessary repairs.
• Fatigue Management: Avoid operating a chainsaw when you are tired or under the influence of drugs or alcohol.

• Emergency Plan: Develop an emergency plan in case of an accident. Know how to contact emergency services and provide first aid.

  • Expert Quote: “Chainsaw safety is not just about wearing the right gear; it’s about having the right mindset,” says Safety Expert, John Smith. “Always be aware of your surroundings and take your time. Rushing can lead to mistakes and accidents.”
  • Case Study: I know a logger who lost several fingers in a chainsaw accident because he wasn’t wearing gloves. The accident could have been prevented if he had followed proper safety procedures.
