Unleashing the Beast: Long Bar Chainsaw Options for Your Stihl 070 (5 Expert Tips)

The Stihl 070. Just saying the name conjures images of raw power and the satisfying roar of a two-stroke engine devouring wood. I remember the first time I saw one; it was in the hands of a seasoned logger who made it look like he was cutting butter with a hot knife. But sometimes, even the mighty 070 needs a little extra reach. That’s where the long bar comes in.

Now, before you go strapping a four-foot bar onto your saw and tackling a redwood, let’s talk strategy. Over the years, I’ve seen folks make some serious blunders with long bars, from overheating their saws to getting pinched tighter than a drum. So, let’s get it right.

1. Understanding the Limits: Bar Length and Engine Power

The first thing to understand is that simply slapping on the longest bar you can find isn’t the way to go. The Stihl 070 is a powerful saw, no doubt, but it still has its limits. You need to match the bar length to the engine’s capabilities.

• Recommended Range: For the 070, I generally recommend sticking to bars between 36 inches and 60 inches. While you can technically go longer, you’ll start to seriously bog down the engine, increase wear and tear, and make the saw incredibly unwieldy.
• The Sweet Spot: In my experience, a 42-inch to 48-inch bar is the sweet spot for most applications. It provides ample reach for felling larger trees and milling decent-sized lumber without overtaxing the engine.
• Why Not Longer? Think of it like this: the longer the bar, the more chain you have to pull through the wood. This requires more power. If the engine is struggling, it will overheat, wear out faster, and your cuts will be slow and uneven. Plus, a longer bar increases the risk of kickback and makes the saw harder to control.

Data Point: A study by the Forest Engineering Research Institute of Canada (FERIC) showed that using an oversized bar on a chainsaw can reduce cutting efficiency by as much as 30% and increase fuel consumption by 20%.

Personal Story: I once saw a guy try to use a 72-inch bar on his 070. He managed to make a few cuts, but the saw was screaming, smoking, and generally sounding like it was about to explode. He ended up burning out the clutch within a week. Lesson learned: respect the saw’s limits!

2. Bar and Chain Selection: Matching Components for Optimal Performance

Choosing the right bar and chain is just as important as selecting the correct length. You need to ensure that the components are compatible and suited for the type of cutting you’ll be doing.

• Bar Types:
  • Solid Bars: These are the most common type and are suitable for general-purpose cutting. They’re durable and relatively inexpensive.
  • Laminated Bars: These are lighter than solid bars, which can be an advantage when using a long bar. They’re also less prone to bending. However, they’re not as durable as solid bars and are more susceptible to damage.
  • Hard-Nose Bars: These have a hardened tip that is more resistant to wear. They’re a good choice for abrasive cutting conditions, such as cutting dirty or sandy wood.
• Chain Types:
  • Full-Chisel Chains: These are the fastest-cutting chains, but they require more skill to use and are more prone to kickback. They’re best suited for clean wood.
  • Semi-Chisel Chains: These are a good compromise between cutting speed and safety. They’re more forgiving than full-chisel chains and are less prone to kickback. They’re a good choice for general-purpose cutting.
  • Low-Profile Chains: These are the safest chains to use, but they’re also the slowest-cutting. They’re a good choice for beginners or for cutting in areas where kickback is a concern.
• Matching the Pitch and Gauge: This is crucial! The pitch is the distance between the chain’s drive links, and the gauge is the thickness of the drive links. The bar and chain must have the same pitch and gauge for them to work together. Your Stihl 070 typically uses a .404″ pitch chain, so make sure your bar is designed for that. The gauge is usually .063″. Check your owner’s manual to confirm.

Wood Science Insight: The type of wood you’re cutting also plays a role in chain selection. Hardwoods like oak and maple require a more aggressive chain, while softwoods like pine and fir can be cut with a less aggressive chain. The moisture content of the wood also affects cutting performance. Wet wood is generally easier to cut than dry wood, but it can also dull the chain faster.

Practical Tip: Always use a chain sharpener to keep your chain sharp. A dull chain will not only cut slower but also put more strain on the saw and increase the risk of kickback.

3. Oiling is Key: Keeping Your Long Bar Properly Lubricated

With a longer bar, proper lubrication becomes even more critical. The chain has to travel a greater distance, which means more friction and heat. If the bar and chain aren’t adequately lubricated, they’ll wear out quickly, and you could even damage the saw.

• Check Your Oiler: Make sure the oiler on your 070 is working correctly. You should see a steady stream of oil coming from the bar when the saw is running. If not, check the oil level, the oil filter, and the oil pump.
• Adjust the Oiler (If Possible): Some 070 models have an adjustable oiler. If yours does, increase the oil flow when using a long bar.
• Use High-Quality Bar and Chain Oil: Don’t skimp on the oil! Use a high-quality bar and chain oil that is specifically designed for chainsaws. This will help to reduce friction, dissipate heat, and prevent rust and corrosion.
• Consider a Supplemental Oiler: For extremely long bars (50 inches and up), you might want to consider using a supplemental oiler. These are small, manually operated oilers that you can use to add extra oil to the bar and chain as needed.

Data Point: A study by Oregon Products found that using a high-quality bar and chain oil can extend the life of the bar and chain by as much as 50%.

Personal Experience: I once neglected to check the oil level on my saw when using a long bar. The bar overheated, turned blue, and the chain seized up. I had to replace both the bar and the chain. It was a costly mistake that I won’t make again.

4. Mastering the Technique: Safe and Effective Long Bar Cutting

Using a long bar requires a different approach than using a shorter bar. You need to be aware of the increased risk of kickback, pinching, and loss of control.

• Stance and Balance: Maintain a wide, stable stance and keep your weight balanced. This will help you control the saw and prevent it from kicking back or getting away from you.
• Cutting Techniques:
  • Avoid Pinching: Pinching occurs when the bar gets stuck in the cut. This can happen if the wood closes in on the bar, or if the chain binds. To avoid pinching, use wedges to keep the cut open, and be careful not to bury the bar too deep in the wood.
  • Use a Felling Lever or Wedges: When felling large trees, always use a felling lever or wedges to help control the direction of the fall. This will prevent the tree from falling in an unexpected direction and potentially causing damage or injury.
  • Boring Cuts: Be extremely cautious when making boring cuts (plunging the bar into the wood). These cuts are particularly prone to kickback. Use a low-kickback chain and keep the saw moving.
• Be Aware of Your Surroundings: Before you start cutting, take a look around and identify any potential hazards, such as power lines, fences, or people. Make sure you have a clear escape route in case the tree falls in an unexpected direction.

Safety First: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, and chaps. Never operate a chainsaw when you’re tired, distracted, or under the influence of drugs or alcohol.

Case Study: A logger was felling a large oak tree with a long bar chainsaw. He failed to use wedges to keep the cut open, and the bar got pinched. The saw kicked back, and he lost control, resulting in a serious leg injury. This incident highlights the importance of using proper techniques and safety precautions when using a long bar chainsaw.

5. Maintenance Matters: Keeping Your 070 and Long Bar in Top Condition

Proper maintenance is essential for keeping your Stihl 070 and long bar in top condition. This will not only extend their lifespan but also ensure that they operate safely and efficiently.

• Regular Cleaning: After each use, clean the bar, chain, and saw. Remove any sawdust, dirt, or debris.
• Sharpen the Chain: Keep your chain sharp. A dull chain will put more strain on the saw and increase the risk of kickback.
• Check the Bar: Inspect the bar for wear and damage. Make sure the rails are straight and the sprocket tip is in good condition.
• Lubricate the Bar: Regularly lubricate the bar with bar and chain oil. This will help to reduce friction and prevent wear.
• Store Properly: When not in use, store the saw and bar in a dry place. This will prevent rust and corrosion.

Tool Maintenance Best Practices: Invest in quality tools for sharpening and maintaining your chainsaw. A good file, depth gauge, and raker gauge are essential for keeping your chain in top condition.

Unique Insight: I’ve found that using compressed air to clean the saw after each use is a great way to remove sawdust and debris from hard-to-reach areas. It also helps to prevent rust and corrosion.

Diving Deeper: The Nitty-Gritty of Wood Processing

Now that we’ve covered the basics of long bar chainsaw usage, let’s delve into some of the more nuanced aspects of wood processing.

Wood Anatomy and Properties

Understanding the anatomy and properties of wood is crucial for making informed decisions about cutting techniques, seasoning methods, and firewood preparation.

• Hardwood vs. Softwood: Hardwoods come from deciduous trees (trees that lose their leaves in the fall), while softwoods come from coniferous trees (trees that have needles and cones). Hardwoods are generally denser and more durable than softwoods, but they can also be more difficult to cut.
• Grain Structure: The grain structure of wood affects its strength, stability, and appearance. Straight-grained wood is easier to split and work with than wood with knots or irregular grain.
• Moisture Content: The moisture content of wood is the amount of water it contains. Freshly cut wood can have a moisture content of 50% or more. As wood dries, it shrinks and becomes more stable. The ideal moisture content for firewood is around 20%.

Data Point: A study by the U.S. Forest Service found that the heat value of firewood increases significantly as the moisture content decreases. Dry firewood can produce up to twice as much heat as green firewood.

Firewood Seasoning Techniques and Safety Considerations

Seasoning firewood is the process of drying it to reduce its moisture content. This makes it easier to light, burn hotter, and produce less smoke.

• Stacking Methods: There are several different methods for stacking firewood, each with its own advantages and disadvantages. Some common methods include:
  • The Traditional Row Stack: This involves stacking the wood in long, parallel rows. This method is easy to do, but it doesn’t allow for good air circulation.
  • The Circular Stack: This involves stacking the wood in a circular pattern. This method provides good air circulation, but it can be more time-consuming to build.
  • The “Holz Hausen” Stack: This is a German method that involves stacking the wood in a circular pattern with a hollow center. This method provides excellent air circulation and is very stable.
• Drying Time: The amount of time it takes to season firewood depends on the type of wood, the climate, and the stacking method. In general, hardwoods take longer to season than softwoods. In a dry climate, firewood can be seasoned in as little as six months. In a humid climate, it may take a year or more.
• Safety Considerations: When handling firewood, always wear gloves to protect your hands from splinters. Be careful when lifting heavy loads, and use proper lifting techniques to avoid back injuries. Never stack firewood near your house or other buildings, as it can attract insects and rodents.

Original Research: I conducted a small-scale experiment to compare the drying times of different firewood stacking methods. I found that the “Holz Hausen” stack dried the fastest, followed by the circular stack, and then the traditional row stack.

Logging Tool Selection and Maintenance Best Practices

In addition to chainsaws, there are a variety of other logging tools that can be used for wood processing. These tools include axes, splitting mauls, wedges, felling levers, and log tongs.

• Axe Selection: Axes come in a variety of sizes and shapes, each designed for a specific purpose. Felling axes are used for felling trees, splitting axes are used for splitting wood, and carving axes are used for carving wood.
• Splitting Maul vs. Hydraulic Splitter: A splitting maul is a heavy, blunt tool that is used to split wood by hand. A hydraulic splitter is a machine that uses hydraulic pressure to split wood. Hydraulic splitters are faster and easier to use than splitting mauls, but they are also more expensive.
• Wedge Types: Wedges are used to help split wood or to prevent a tree from pinching the chainsaw bar. There are several different types of wedges, including steel wedges, plastic wedges, and wooden wedges.
• Maintenance Best Practices: Keep your logging tools clean and sharp. Sharpen axes and mauls regularly, and lubricate moving parts. Store tools in a dry place to prevent rust and corrosion.

Project Planning and Execution

Before you start any wood processing project, it’s important to plan ahead and execute the project safely and efficiently.

• Assess the Site: Take a look at the site where you’ll be working and identify any potential hazards, such as power lines, fences, or people.
• Develop a Plan: Develop a plan for how you’ll fell the trees, split the wood, and stack the firewood.
• Gather Your Tools: Make sure you have all the tools you need before you start working.
• Work Safely: Always work safely, and follow all safety precautions.

Real-World Example: I was hired to clear a small lot of trees for a new construction project. Before I started working, I assessed the site and identified several potential hazards, including a power line and a nearby house. I developed a plan for how I would fell the trees safely, and I gathered all the tools I needed. I worked carefully and followed all safety precautions, and the project was completed without any incidents.
