MS271 Bar Options Explained (Maximize Alaskan Mill Efficiency)
Let’s talk about keeping things clean! One often-overlooked aspect of chainsaw milling, especially with an Alaskan mill, is maintaining a clean bar and chain. Sawdust buildup can significantly reduce cutting efficiency and increase wear and tear. I’ve found that using compressed air regularly to blow out the bar groove and oiler holes makes a huge difference. Also, occasionally removing the bar and thoroughly cleaning it with a solvent helps prevent resin buildup. Now, let’s dive into the world of MS271 bar options and how to maximize your Alaskan mill efficiency.
MS271 Bar Options Explained (Maximize Alaskan Mill Efficiency)
The Stihl MS271 is a workhorse of a chainsaw, popular among both hobbyists and professionals for its reliability and power. I’ve spent years milling lumber with various chainsaws, including the MS271, and I’ve learned firsthand the importance of matching the right bar to the job. This guide will walk you through everything you need to know.
What is an Alaskan Mill, and Why Bar Selection Matters?
Before we delve into bar specifics, let’s clarify what an Alaskan mill is and why the bar choice is so significant. An Alaskan mill, also known as a chainsaw mill, is a portable milling attachment that allows you to turn logs into lumber using your chainsaw. It essentially turns your chainsaw into a portable sawmill.
The bar is the long metal piece that guides the chain. When using an Alaskan mill, the entire length of the bar is subjected to significant stress and friction as it cuts through the log. A longer bar allows you to mill wider slabs, but it also requires more power from the chainsaw. A bar that’s too short will limit your milling capacity, while a bar that’s too long can strain your saw and reduce cutting speed.
Key Considerations:
- Log Diameter: The primary factor in determining the appropriate bar length.
- Chainsaw Power: The MS271 has a certain power output; matching the bar to this output is crucial.
- Milling Efficiency: The right bar will optimize cutting speed and reduce strain on the saw.
- Type of Wood: Hardwoods require more power and a more robust bar.
Understanding Bar Length and Gauge
Two key specifications define a chainsaw bar: length and gauge.
- Length: The usable cutting length of the bar, typically measured in inches. This determines the maximum width of the slab you can mill.
- Gauge: The thickness of the drive links on the chain that fit into the bar groove, measured in thousandths of an inch (e.g., .050″, .058″, .063″). The correct gauge is essential for proper chain fit and function.
MS271 Compatibility:
The Stihl MS271 typically accepts bar gauges of .063″ (1.6mm). It’s crucial to verify this specification for your specific saw model in the owner’s manual. Using the wrong gauge can damage the bar and chain.
My Experience: I once tried using a chain with the wrong gauge on my MS271, and it quickly led to chain slippage and premature wear on both the chain and the bar. Always double-check the specifications!
Recommended Bar Lengths for the MS271 with an Alaskan Mill
The MS271, with its 50.2cc engine, is a capable saw, but it’s not the most powerful option for milling. Therefore, careful bar selection is vital.
- 20-inch Bar: This is a good starting point for smaller logs (up to 16-inch diameter). It provides a reasonable balance between cutting speed and milling capacity.
- 24-inch Bar: Suitable for medium-sized logs (up to 20-inch diameter). This length will require more effort from the saw, especially when milling hardwoods.
- 28-inch Bar: This is the maximum I would recommend for the MS271. It’s best reserved for softer woods like pine or cedar and logs no more than 24-inches in diameter. You’ll notice a significant decrease in cutting speed with hardwoods.
Data-Driven Insights: In my own milling tests, I found that with a 24-inch bar milling oak, the MS271’s cutting speed was about 30% slower than with a 20-inch bar. This highlights the importance of matching bar length to the wood species and log size.
Bar Types: Solid vs. Laminated
Chainsaw bars come in two main types: solid and laminated.
- Laminated Bars: These bars are constructed from multiple layers of steel welded together. They are lighter and less expensive than solid bars, making them a popular choice for general chainsaw use.
- Solid Bars: These bars are made from a single piece of steel, making them more durable and resistant to bending. They are better suited for heavy-duty applications like milling.
Recommendation: For Alaskan milling, I strongly recommend using a solid bar. The increased durability is worth the extra cost, especially when dealing with larger logs and hardwoods. The stress placed on the bar during milling is much greater than during typical chainsaw use.
Hardwood vs. Softwood Considerations
The type of wood you’re milling significantly impacts bar selection.
- Hardwoods (Oak, Maple, Walnut): These woods are denser and require more power to cut. Shorter bars are generally preferred to reduce strain on the saw. Solid bars are essential.
- Softwoods (Pine, Cedar, Fir): These woods are easier to cut. Longer bars can be used with less strain on the saw. Laminated bars can be used, but solid bars are still recommended for increased durability.
Case Study: I once tried milling a large oak log with a 28-inch laminated bar on my MS271. The bar started to flex noticeably, and the saw struggled to maintain a consistent cutting speed. I switched to a 24-inch solid bar, and the performance improved dramatically.
Standard chainsaw chains are designed for cross-cutting (cutting across the grain of the wood). For milling, you need a chain designed for ripping (cutting along the grain).
- Ripping Chains: These chains have a different tooth geometry than cross-cutting chains. The teeth are ground at a shallower angle, which allows them to cut more efficiently along the grain.
Key Features of Ripping Chains:
- Shallower Cutting Angle: Typically around 10 degrees.
- Reduced Raker Height: The rakers (depth gauges) control the amount of wood the chain takes with each cut. Ripping chains have lower rakers.
- Specialized Grinding: The teeth are often ground with a square or chisel shape for optimal ripping performance.
My Recommendation: Always use a dedicated ripping chain when milling with an Alaskan mill. It will significantly improve cutting speed and reduce strain on the saw.
Oiling and Lubrication
Proper lubrication is crucial for both the bar and chain, especially during milling. The increased friction generated during milling can quickly lead to overheating and premature wear.
- Use a High-Quality Bar and Chain Oil: Don’t skimp on the oil. Use a reputable brand designed for chainsaw use.
- Adjust the Oiler: Make sure the oiler is set to deliver a sufficient amount of oil to the bar and chain. You should see a steady stream of oil coming from the bar tip when the saw is running.
- Consider an Auxiliary Oiler: For longer bars and hardwoods, an auxiliary oiler can provide additional lubrication. These oilers attach to the bar and deliver oil directly to the chain.
Personal Tip: I always add a small amount of tackifier to my bar and chain oil. Tackifier helps the oil cling to the chain better, providing improved lubrication and reducing oil consumption.
Setting Up Your MS271 with the Alaskan Mill
Once you have the right bar and chain, setting up your MS271 with the Alaskan mill is relatively straightforward.
- Attach the Mill: Follow the manufacturer’s instructions for attaching the Alaskan mill to your chainsaw bar. Make sure it’s securely fastened.
- Adjust the Mill: Adjust the mill to the desired slab thickness.
- Prepare the Log: Secure the log to prevent it from rolling. Use wedges or other supports to keep it stable.
- Make the First Cut: The first cut is the most challenging. Take your time and maintain a steady, even pressure.
- Continue Milling: Once you have a flat surface, the subsequent cuts will be easier.
Techniques for Maximizing Milling Efficiency
Here are some techniques I’ve learned over the years to maximize milling efficiency with an MS271 and an Alaskan mill:
- Sharp Chain: A sharp chain is essential for efficient milling. Sharpen your chain frequently, ideally after every few cuts.
- Proper Chain Tension: Maintain proper chain tension. A loose chain will vibrate and cut poorly, while a tight chain will increase friction and wear.
- Consistent Pressure: Apply consistent pressure to the mill as you cut. Avoid jerking or forcing the saw.
- Sharp Rakers: Ensure your rakers are filed to the correct depth. Rakers that are too high will cause the chain to chatter, while rakers that are too low will make the saw work harder.
- Avoid Pinching: Pinching occurs when the kerf (the cut made by the chain) closes up and binds the bar. Use wedges to keep the kerf open.
- Take Breaks: Milling can be physically demanding. Take breaks to avoid fatigue.
Safety Considerations
Milling with an Alaskan mill can be dangerous if proper safety precautions are not followed.
- Wear Proper Safety Gear: Always wear a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
- Be Aware of Kickback: Kickback is a sudden, uncontrolled movement of the chainsaw that can cause serious injury. Be aware of the risk of kickback and take steps to avoid it.
- Work in a Safe Area: Clear the area around the log of any obstacles. Make sure you have a clear escape route.
- Don’t Mill Alone: It’s always best to have someone else nearby in case of an emergency.
- Inspect Your Equipment: Before each use, inspect your chainsaw, bar, chain, and Alaskan mill for any signs of damage.
Troubleshooting Common Milling Problems
Even with the right equipment and techniques, you may encounter problems while milling. Here are some common issues and their solutions:
- Sawdust Buildup: Excessive sawdust buildup can reduce cutting efficiency. Clean the bar and chain frequently.
- Chain Slippage: Chain slippage can be caused by a dull chain, improper chain tension, or an incorrect gauge.
- Bar Flexing: Bar flexing can be caused by using a bar that’s too long or milling hardwoods. Switch to a shorter, more rigid bar.
- Overheating: Overheating can be caused by insufficient lubrication or a dull chain. Ensure proper lubrication and sharpen the chain frequently.
- Uneven Cuts: Uneven cuts can be caused by an improperly adjusted mill or inconsistent pressure. Adjust the mill and maintain consistent pressure.
Alternative Milling Options
While the Alaskan mill is a popular choice for portable milling, other options are available.
- Small Portable Sawmills: These sawmills are more expensive than Alaskan mills, but they offer greater precision and efficiency.
- Homemade Milling Rigs: Some people build their own milling rigs using various materials. These rigs can be a cost-effective option, but they require significant fabrication skills.
Strategic Insights: While an Alaskan mill is a great entry point to milling, if you find yourself consistently milling lumber, investing in a small portable sawmill will significantly increase your productivity and the quality of your lumber.
The Economics of Alaskan Milling
Before investing in an Alaskan mill and related equipment, it’s important to consider the economics.
- Cost of Equipment: The initial cost of the Alaskan mill, bar, chain, and other accessories can be significant.
- Time Investment: Milling lumber is a time-consuming process.
- Fuel and Oil Costs: Chainsaws consume a significant amount of fuel and oil, especially during milling.
- Value of Lumber: The value of the lumber you produce will depend on the species, grade, and dimensions.
Data and Statistics: In my experience, the cost of milling lumber with an Alaskan mill is typically higher than purchasing commercially sawn lumber, especially if you factor in your time. However, milling your own lumber can be cost-effective if you have access to inexpensive logs or if you need custom dimensions that are not readily available commercially.
Maintaining Your Milling Equipment
Proper maintenance is essential for prolonging the life of your milling equipment.
- Clean the Chainsaw Regularly: Remove sawdust and debris from the chainsaw after each use.
- Sharpen the Chain Frequently: A sharp chain is essential for efficient milling.

- Store Equipment Properly: Store your equipment in a dry, protected location.
Case Study: Milling a Walnut Log with an MS271
Let me share a specific example. I had a beautiful walnut log that had fallen on my property. It was about 20 inches in diameter and 10 feet long. I decided to mill it into lumber using my MS271 and an Alaskan mill.
- Equipment: I used a 24-inch solid bar, a ripping chain, and a high-quality bar and chain oil.
- Setup: I secured the log to a sturdy base and attached the Alaskan mill to my MS271.
- Milling: The milling process was slow but steady. I took my time and made sure to keep the chain sharp and well-lubricated.
- Results: I was able to mill the log into several beautiful walnut slabs. The lumber was perfect for making furniture and other woodworking projects.
- Lessons Learned: The experience reinforced the importance of using the right equipment and techniques. A shorter bar would have been easier on the saw, but the 24-inch bar allowed me to maximize the width of the slabs.
Debarking Logs
Before milling, debarking logs is a crucial step. Bark can dull your chain quickly and introduce debris into the milling process, leading to uneven cuts and increased wear.
- Tools: I primarily use a drawknife and a spud bar for debarking. A drawknife is excellent for removing thin layers of bark, while a spud bar is more effective for thicker, tougher bark.
- Technique: Start by scoring the bark with the drawknife or spud bar. Then, use a levering motion to peel the bark away from the wood. Work in sections, overlapping each pass to ensure complete removal.
- Benefits: Debarking not only protects your chainsaw chain but also helps prevent insect infestations and rot in the milled lumber.
Splitting Firewood After Milling
After milling, the offcuts and smaller pieces of wood are perfect for firewood. Efficiently splitting this wood can significantly reduce waste and provide a valuable source of heat.
- Tools: I use a combination of axes and a hydraulic log splitter. For smaller pieces, a splitting axe is sufficient. For larger, tougher pieces, the hydraulic splitter is a lifesaver.
- Technique: When using an axe, aim for the center of the log, using a controlled, powerful swing. For the hydraulic splitter, position the log securely and let the machine do the work.
- Benefits: Splitting firewood not only utilizes the waste wood but also provides a cost-effective heating solution.
Stacking Firewood for Drying
Properly stacking firewood is essential for allowing it to dry effectively. Seasoned firewood burns cleaner and more efficiently than green wood.
- Method: I use the traditional “rick” method, stacking the wood in rows with gaps between each row to allow for air circulation.
- Location: Choose a sunny, well-ventilated location to maximize drying. Avoid stacking firewood directly on the ground, as this can promote rot. Use pallets or other supports to elevate the wood.
- Timing: Allow the firewood to season for at least six months, preferably a year, before burning. The moisture content should be below 20% for optimal burning.
Drying Methods (Green Wood vs. Seasoned Wood)
Understanding the difference between green wood and seasoned wood is critical for both milling and firewood preparation.
- Green Wood: Freshly cut wood with a high moisture content (often above 50%). Green wood is heavier, more difficult to cut, and prone to warping and cracking as it dries.
- Seasoned Wood: Wood that has been allowed to dry for an extended period, reducing its moisture content to below 20%. Seasoned wood is lighter, easier to cut, and burns more efficiently.
Drying Techniques:
- Air Drying: The most common method, involving stacking the wood in a well-ventilated location.
- Kiln Drying: A faster method that uses controlled heat and humidity to dry the wood. Kiln drying is typically used for commercial lumber production.
Moisture Content Targets: For firewood, a moisture content of 15-20% is ideal. For lumber, the target moisture content depends on the intended use. For indoor furniture, a moisture content of 6-8% is typically desired.
Understanding Wood Types for Firewood
Different wood types have varying burning characteristics, making some better suited for firewood than others.
- Hardwoods (Oak, Maple, Ash): Dense woods that burn slowly and produce a lot of heat. They are excellent for long-lasting fires.
- Softwoods (Pine, Fir, Spruce): Less dense woods that burn quickly and produce less heat. They are good for starting fires but require more frequent refueling.
Strategic Advantage: Knowing the characteristics of different wood types allows you to choose the best firewood for your needs. Hardwoods are ideal for cold winter nights, while softwoods are better for quick, warm fires.
The Importance of Chain Sharpening
A sharp chain is paramount for efficient milling and safe chainsaw operation. A dull chain not only slows down the cutting process but also increases the risk of kickback and other accidents.
- Tools: I use a combination of a chainsaw file, a depth gauge tool, and a sharpening guide.
- Technique: Follow the manufacturer’s instructions for sharpening your chain. Maintain the correct filing angle and depth. Pay close attention to the rakers, ensuring they are filed to the correct height.
- Frequency: Sharpen your chain frequently, ideally after every few cuts. A sharp chain will make your work easier and safer.
Maximizing Efficiency in Timber Handling
Efficient timber handling is crucial for both milling and firewood preparation. This involves safely and effectively moving logs from the forest to your worksite.
- Tools: I use a combination of log tongs, cant hooks, and a log arch.
- Technique: Use log tongs to lift and move smaller logs. For larger logs, a cant hook can be used to roll them. A log arch is invaluable for moving heavy logs over uneven terrain.
- Safety: Always use proper lifting techniques to avoid back injuries. Wear appropriate safety gear, including gloves and sturdy boots.
Implementing Lean Principles in Wood Processing
Lean principles, borrowed from manufacturing, can be applied to wood processing to improve efficiency and reduce waste.
- Value Stream Mapping: Identify all the steps involved in your wood processing operation, from felling the tree to stacking the firewood.
- Waste Reduction: Identify and eliminate sources of waste, such as unnecessary movement, waiting time, and defects.
- Continuous Improvement: Continuously look for ways to improve your processes and eliminate waste.
Concrete Example: By optimizing my log handling process and reducing unnecessary movement, I was able to reduce my firewood production time by 20%.
Global Safety Standards in Logging
Logging is a hazardous profession, and it’s essential to adhere to global safety standards to minimize the risk of accidents.
