Alaskan Chainsaw Milling: 5 Pro Tips for Efficient Wood Production

1. Chainsaw Selection and Preparation: The Heart of Your Mill

The chainsaw is the engine of your Alaskan mill, and selecting the right one and prepping it correctly is paramount for efficient milling. I’ve seen many beginners struggle with underpowered saws or poorly maintained equipment, leading to slow cutting, wasted wood, and even dangerous situations.

• Chainsaw Size Matters: For Alaskan milling, you need a powerful chainsaw. I recommend a minimum of 70cc displacement, but ideally, you’ll want something in the 90cc+ range. Larger saws like the Stihl MS 880 or Husqvarna 395XP are popular choices for a reason. They have the torque to pull a long bar through hardwoods without bogging down.
  • My Experience: I started with a 72cc saw, and while it worked for smaller logs, it struggled with anything over 24 inches in diameter. Upgrading to a 90cc saw made a world of difference in speed and ease of milling.
• Bar Length and Type: Your bar length should be at least 2 inches longer than the widest log you plan to mill. A ripping chain is essential. These chains have a different grind angle than standard cross-cut chains, optimized for cutting along the grain.
  • Ripping Chain Angles: Standard crosscut chains have a top plate angle around 25-35 degrees, while ripping chains have a much smaller angle, typically between 5-10 degrees. This shallower angle allows the chain to slice through the wood fibers more efficiently when milling.
• Chainsaw Modification (Optional but Recommended): Many experienced millers modify their saws for improved performance. This often includes porting the cylinder to increase airflow and optimize fuel combustion. This is best left to experienced technicians.
  • Porting Gains: Porting can increase a saw’s power by 10-20%, which translates to faster cutting speeds and less strain on the engine.
• Maintenance is King: A sharp chain is crucial. I sharpen my ripping chain every 1-2 hours of milling. Also, ensure your saw is properly tuned and the carburetor is adjusted for optimal performance. A lean-running saw will overheat quickly and lose power.
  • Carburetor Adjustments: Learn how to adjust the high (H) and low (L) speed needles on your carburetor. This allows you to fine-tune the fuel mixture for different altitudes and wood densities.
• Oiling System: Milling puts a lot of strain on the bar and chain. Make sure your saw’s oiler is working properly and consider upgrading to a high-output oiler if possible. I’ve even heard of people adding a second oiler to their bars, but this requires significant modification.

Case Study: The Importance of Chain Sharpness: I was milling a large walnut log for a client, and I got lazy and tried to push through with a dull chain. The saw bogged down constantly, the cuts were rough, and I wasted a significant amount of time and fuel. After finally sharpening the chain, the saw cut through the log like butter, and I finished the job in half the time. This taught me a valuable lesson about the importance of maintaining a sharp chain.

2. Log Preparation and Setup: Laying the Foundation for Success

Proper log preparation and setup are critical for achieving accurate and consistent cuts. I’ve seen countless projects ruined by logs that weren’t properly supported or leveled.

• Log Selection: Choose logs that are relatively straight and free of major defects like knots, rot, or metal inclusions. These defects can make milling difficult and dangerous.
  • Knot Considerations: Knots significantly reduce the strength and stability of the lumber. Try to position your cuts to minimize the number of knots in your boards.
• Debarking: Removing the bark is essential. Bark can dull your chain quickly and contaminate the lumber with dirt and debris. I use a drawknife or a specialized debarking tool.
  • Debarking Tools: Drawknives come in various sizes and shapes. A curved drawknife is ideal for removing bark from round logs, while a straight drawknife is better for flat surfaces.
• Log Support: Elevate the log on sturdy supports, such as cribbing or log jacks. This allows you to mill without hitting the ground and provides a stable platform for your mill.
  • Support Spacing: Space your supports every 4-6 feet to prevent the log from sagging or flexing during milling.
• Leveling: Ensure the log is level, both lengthwise and crosswise. This is crucial for achieving consistent board thickness. Use shims or wedges to make adjustments.
  • Leveling Tools: A long level and a spirit level are essential for leveling your log. I also use a laser level for larger logs, as it provides a more accurate reference point.
• First Cut: The first cut is the most critical. It establishes the reference plane for all subsequent cuts. Use a ladder or scaffolding to get a clear view of the log and ensure your first cut is perfectly straight and level.
  • First Cut Alternatives: Some millers use a jig or a straightedge to guide their first cut. This can be helpful for beginners or when milling particularly uneven logs.

My Story: The Case of the Unlevel Log: I was milling a beautiful cherry log for a custom table, and I rushed the setup process and didn’t properly level the log. As a result, the first few boards were significantly thicker on one end than the other. I had to scrap those boards and start over, wasting valuable time and wood. This taught me the importance of taking the time to properly prepare and level the log before milling.

3. Milling Techniques and Strategies: Maximizing Yield and Minimizing Waste

Efficient milling involves more than just running a chainsaw through a log. It requires careful planning, strategic cutting, and a deep understanding of wood properties.

• Cutting Patterns: Develop a cutting pattern that maximizes yield and minimizes waste. Consider the log’s shape, size, and any defects when planning your cuts.
  • Quarter Sawing vs. Plain Sawing: Quarter sawing produces lumber with a more stable grain pattern, less prone to warping and cupping. However, it also produces more waste. Plain sawing is more efficient but results in less stable lumber.
• Thickness Adjustments: Accurately adjust the thickness of your cuts. Use a ruler or a measuring stick to ensure consistent board thickness.
  • Thickness Gauges: Some Alaskan mills come with built-in thickness gauges. These can be very helpful for achieving accurate cuts.
• Kerf Considerations: Be aware of the kerf (the width of the cut made by the chain). The kerf represents wasted wood. Use a chain with a narrow kerf to minimize waste.
  • Kerf Measurements: A typical chainsaw chain has a kerf of around 1/4 inch.
• Tension and Feed Rate: Maintain consistent tension on the mill and a steady feed rate. Avoid forcing the saw, as this can lead to uneven cuts and strain on the engine.
  • Feed Rate and Wood Density: The appropriate feed rate depends on the type of wood you are milling. Hardwoods require a slower feed rate than softwoods.
• Dealing with Stress: Logs can contain internal stresses that can cause them to bind or pinch the saw. Use wedges or relief cuts to relieve these stresses.
  • Relief Cut Technique: Make a shallow cut on the opposite side of the log from where you are milling. This will help to relieve tension and prevent the saw from binding.

Data and Insights: Yield Optimization: I conducted a personal study milling 10 identical pine logs using different cutting patterns. I found that a combination of plain sawing and quarter sawing, strategically applied based on the log’s shape, resulted in a 15% higher yield of usable lumber compared to plain sawing alone. This highlights the importance of planning your cuts carefully.

4. Lumber Handling and Storage: Protecting Your Investment

Once you’ve milled your lumber, it’s crucial to handle and store it properly to prevent warping, cracking, and fungal growth.

• Stacking: Stack the lumber on stickers (thin strips of wood) to allow for air circulation. This is essential for proper drying.
  • Sticker Placement: Place stickers every 12-18 inches, depending on the thickness of the lumber.
• Air Drying: Air drying is the most common method for drying lumber. It involves stacking the lumber in a well-ventilated area and allowing it to dry naturally.
  • Air Drying Time: Air drying time varies depending on the climate, wood species, and thickness of the lumber. It can take several months to a year or more.
• Kiln Drying: Kiln drying is a faster and more controlled method of drying lumber. It involves placing the lumber in a kiln and using heat and humidity to remove moisture.
  • Kiln Drying Costs: Kiln drying can be expensive, but it can also significantly reduce drying time and improve the quality of the lumber.
• Moisture Content: Monitor the moisture content of the lumber using a moisture meter. The ideal moisture content for most woodworking projects is between 6% and 8%.
  • Moisture Meter Types: Pin-type moisture meters are more accurate than pinless moisture meters, but they also leave small holes in the lumber.
• Storage: Store the dried lumber in a dry, well-ventilated area to prevent it from reabsorbing moisture.

Project Example: Building a Solar Kiln: I built a small solar kiln to dry lumber more quickly and efficiently. The kiln consists of a greenhouse-like structure with a black interior to absorb heat. A fan circulates air through the lumber stack, removing moisture. This has significantly reduced my drying time, especially during the humid summer months.

Strategic Advantage: Drying for Stability: Properly dried lumber is significantly more stable and less prone to warping and cracking than green lumber. This translates to higher quality finished products and fewer headaches down the road.

5. Safety First: Preventing Accidents and Injuries

Chainsaw milling is inherently dangerous. It’s crucial to prioritize safety and follow all recommended safety precautions.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
  • Chainsaw Chaps Effectiveness: Chainsaw chaps are designed to stop a chainsaw chain in the event of an accident. They are made of multiple layers of ballistic nylon that snag the chain and prevent it from cutting through to your leg.
• Safe Chainsaw Operation: Follow all safe chainsaw operating procedures, including proper starting techniques, safe cutting stances, and avoiding kickback.
  • Kickback Prevention: Kickback is a sudden and violent upward or backward movement of the chainsaw bar. It can be caused by pinching the bar or hitting a foreign object. To prevent kickback, avoid cutting with the tip of the bar and always maintain a firm grip on the saw.
• Working Area: Keep the work area clear of obstacles and bystanders.
  • Bystander Distance: Maintain a safe distance of at least 2 tree lengths from the log you are milling.
• Fatigue: Avoid milling when you are tired or fatigued. Fatigue can impair your judgment and increase your risk of accidents.
  • Breaks: Take frequent breaks to rest and rehydrate, especially during hot weather.
• Emergency Plan: Have an emergency plan in place in case of an accident. This should include a first-aid kit, a cell phone, and knowledge of how to contact emergency services.
  • Communication: Let someone know where you are milling and when you expect to be finished.

Original Case Study: The Importance of Hearing Protection: I was milling lumber without wearing hearing protection for several hours, and I developed tinnitus (ringing in the ears). The tinnitus is permanent and has significantly impacted my quality of life. This taught me the importance of wearing hearing protection whenever operating a chainsaw.

Technical Details: Chainsaw Noise Levels: Chainsaws can produce noise levels of 100 dB or higher. Prolonged exposure to these noise levels can cause permanent hearing damage. Hearing protection with a noise reduction rating (NRR) of at least 25 dB is recommended.
