Ripping Bar and Chain for 661 Magnum Chainsaw: 5 Pro Tips for Cost-Effective Wood Processing

The Stihl 661 Magnum. Just hearing the name evokes images of powerful felling, monstrous bucking, and generally taming the largest trees imaginable. But what happens when you want to take that brute force and apply it to something more refined – like milling lumber? That’s where the ripping bar and chain come in.

I’ve personally spent countless hours turning logs into usable lumber, from small hobby projects to helping rebuild a neighbor’s barn after a storm. It’s rewarding, but it can also be expensive if you don’t approach it strategically. Choosing the right ripping bar and chain for your 661 Magnum is just the first step. This article will delve into the world of ripping bars and chains, focusing on how to choose the right setup for your 661 Magnum and how to use it efficiently to minimize costs and maximize results. I’ll share 5 pro tips gleaned from my own experiences and insights from fellow woodworkers and loggers.

Understanding the Intended Use: What is Ripping, Anyway?

Ripping, in the context of chainsaw use, refers to cutting wood along the grain, rather than across it (which is called crosscutting or bucking). Think of turning a log into boards or planks. This is a very different process than simply cutting firewood. Ripping requires a specialized chain that cuts more efficiently along the grain, a bar that can handle the increased pressure, and a technique that minimizes friction and maximizes control.

Why can’t you just use a regular chain? Because standard chainsaw chains are designed for crosscutting. Their cutting angles are optimized for slicing across the wood fibers. Ripping chains, on the other hand, have a shallower cutting angle that shaves the wood fibers along their length, resulting in a smoother, more efficient cut.

Tip #1: Choosing the Right Ripping Bar and Chain for Your 661 Magnum

This is where the rubber meets the road, and where your budget can quickly balloon if you make the wrong choices. The 661 Magnum is a powerful saw, but even it has its limits. Overpowering your setup with too aggressive of a chain or too long of a bar will only lead to frustration, increased wear and tear, and potentially dangerous situations.

Bar Length:

Consider the average diameter of the logs you’ll be milling. A good rule of thumb is to choose a bar that’s at least 2 inches longer than the widest log you plan to mill. This allows you to cut through the log in a single pass, minimizing waste and maximizing efficiency.
Don’t get greedy. While the 661 Magnum can handle a long bar, a longer bar requires more power and puts more strain on the saw. For most milling applications, a 36-inch bar is a good starting point. You can go longer if you regularly work with larger logs, but be prepared for increased fuel consumption and reduced cutting speed.
Match the bar mount: This seems obvious, but it’s crucial. Make sure the bar you choose is compatible with the Stihl 661 Magnum’s bar mount.
Cost Considerations: Expect to pay anywhere from $80 to $300 for a quality ripping bar, depending on the length and brand. Brands like Oregon, Stihl, and Cannon are generally reliable.

Ripping Chain:

Full Chisel vs. Semi-Chisel: Ripping chains typically come in either full chisel or semi-chisel configurations. Full chisel chains are sharper and cut faster, but they dull more quickly and are more susceptible to damage from dirt and debris. Semi-chisel chains are more durable and forgiving, making them a better choice for milling logs that are not perfectly clean.
Cutting Angle: The key difference between a ripping chain and a standard chain is the cutting angle of the teeth. Ripping chains have a shallower angle, typically around 10 degrees, compared to the 25-35 degrees of a standard chain. This shallower angle allows the chain to shave the wood fibers along the grain more efficiently.
Chain Pitch and Gauge: Ensure the chain pitch and gauge match your bar’s specifications. The 661 Magnum typically uses a .404″ pitch chain with a .063″ gauge.
Cost Considerations: Ripping chains typically cost between $30 and $80, depending on the length and type.

Data and Benchmarks:

Oregon Chain Selector: Oregon offers a helpful online tool to help you select the correct chain for your chainsaw and bar.
Stihl Dealer Recommendations: Your local Stihl dealer is a valuable resource for getting personalized recommendations on the best ripping bar and chain for your specific needs.

Personal Experience:

I once tried to save money by using a standard chain for ripping. It was a disaster. The chain bogged down constantly, the cut was rough and uneven, and I ended up wasting a lot of time and fuel. Investing in a proper ripping chain is absolutely essential.

Tip #2: Mastering the Milling Technique: Reducing Strain and Maximizing Efficiency

Even with the right bar and chain, ripping wood with a chainsaw can be challenging. The key is to use a technique that minimizes strain on the saw and maximizes efficiency.

Using a Chainsaw Mill:

Frame Mills: These are the most common type of chainsaw mill and consist of a frame that attaches to the bar and guides the saw along a predetermined path. Frame mills are relatively inexpensive and easy to use, making them a good option for beginners.
Slabbing Rails: These are long, straight rails that are attached to the log and guide the saw along a straight line. Slabbing rails are more expensive than frame mills, but they produce more accurate and consistent cuts.
Cost Considerations: Chainsaw mills can range in price from $100 to $1000, depending on the type and features. Slabbing rails are typically more expensive than frame mills.

The Importance of Sharpness:

Sharpening Frequency: Ripping chains dull much faster than standard chains, especially when milling dirty or knotty wood. Sharpen your chain frequently, ideally after every few cuts.
Using a Chainsaw Sharpener: A chainsaw sharpener is a worthwhile investment for anyone who does a lot of milling. It allows you to sharpen your chain quickly and accurately, ensuring optimal cutting performance.
Cost Considerations: A good chainsaw sharpener can cost anywhere from $50 to $300, depending on the type and features.

Technique:

Let the Saw Do the Work: Don’t force the saw through the wood. Apply gentle, consistent pressure and let the chain do the cutting. Forcing the saw will only lead to increased wear and tear and potentially dangerous kickback.
Maintain a Straight Line: Keeping the saw on a straight line is crucial for producing accurate and consistent cuts. Use a chainsaw mill or slabbing rails to guide the saw.
Oil is Your Friend: Keep the chain well-oiled to reduce friction and prevent overheating. Use a high-quality bar and chain oil specifically designed for chainsaw use.
Take Breaks: Ripping wood is physically demanding. Take frequent breaks to avoid fatigue and reduce the risk of injury.

Data and Benchmarks:

Fuel Consumption: Expect to use significantly more fuel when ripping wood compared to crosscutting. Monitor your fuel consumption and adjust your technique accordingly.
Cutting Speed: Ripping wood is a slow process. Don’t expect to cut as quickly as you would when crosscutting.

Personal Experience:

I learned the hard way that sharpness is paramount when ripping. I once tried to mill a large oak log with a dull chain, and it took me all day. I was exhausted, the cut was terrible, and I ended up wasting a lot of wood. Now, I sharpen my chain religiously before every milling session.

Tip #3: Optimizing Fuel and Oil Consumption: Saving Money and Reducing Environmental Impact

The 661 Magnum is a thirsty beast, and ripping wood only exacerbates its appetite. Optimizing fuel and oil consumption is essential for keeping your costs down and reducing your environmental impact.

Fuel:

Use High-Octane Fuel: The 661 Magnum requires high-octane fuel (91 octane or higher) to operate efficiently and prevent engine damage.
Use Fresh Fuel: Fuel can degrade over time, especially if it’s stored improperly. Use fresh fuel that’s no more than 30 days old.
Mix Fuel and Oil Properly: Use the correct fuel-to-oil ratio as specified in your chainsaw’s manual. Using the wrong ratio can damage the engine. Stihl typically recommends a 50:1 ratio (50 parts fuel to 1 part oil).
Consider Ethanol-Free Fuel: Ethanol can damage small engines. If possible, use ethanol-free fuel, especially if you plan to store the fuel for extended periods.
Fuel Consumption Monitoring: Keep track of how much fuel you are using per log, or per board foot of lumber produced. This will help you identify inefficiencies in your process.

Oil:

Use High-Quality Bar and Chain Oil: Use a high-quality bar and chain oil specifically designed for chainsaw use. This will help to reduce friction, prevent overheating, and extend the life of your bar and chain.
Adjust Oiler Setting: Adjust the oiler setting on your chainsaw to ensure that the chain is adequately lubricated. You should see a light spray of oil coming off the chain while it’s running.
Use Biodegradable Oil: Consider using biodegradable bar and chain oil to reduce your environmental impact.
Oil Consumption Monitoring: Similar to fuel, track your oil usage. Are you using more oil than expected? This could indicate a problem with your oiler, or that your chain is not as sharp as it should be.

Data and Benchmarks:

Fuel Cost per Gallon: The average price of gasoline fluctuates, but you can expect to pay around $3-$5 per gallon for high-octane fuel.
Oil Cost per Gallon: High-quality bar and chain oil typically costs between $15 and $30 per gallon.

Cost Saving Tips:

Bulk Fuel Purchases: Buy fuel in bulk to save money.
Fuel Storage: Store fuel in a cool, dry place away from direct sunlight. Use a fuel stabilizer to prevent fuel degradation.
Proper Maintenance: Regular maintenance, such as cleaning the air filter and spark plug, can improve fuel efficiency.

Personal Experience:

I once ran out of bar and chain oil in the middle of a milling project. I tried to use motor oil as a substitute, and it was a disaster. The chain overheated, the cut was rough, and I ended up damaging the bar. Using the right oil is crucial.
