Carlton File O Plate Revival (7 Insider Tips For Sharp Chains)

Just like an onion, there are levels to this process. Today, we’re peeling back those layers to revive your Carlton File-O-Plate, that trusty sidekick that might be gathering dust in your workshop. We’re diving deep into sharpening, cost considerations, and everything in between to ensure your saw is always ready to rip.

Carlton File-O-Plate Revival: 7 Insider Tips for Sharp Chains

The Carlton File-O-Plate. It’s a name that probably conjures up memories for many seasoned woodcutters, perhaps even a bit of nostalgia. It’s a simple, yet effective, tool for maintaining your chainsaw chain’s sharpness. But sometimes, it needs a little… revival. We’re not just talking about basic filing; we’re talking about optimizing your technique, understanding the nuances of your chain, and ultimately, getting the most bang for your buck from your chainsaw.

1. Understanding Your Chain: The Foundation of Sharpness

Before you even pick up the File-O-Plate, you need to know your chain. What’s the pitch? What’s the gauge? Are you working with standard, semi-chisel, or full-chisel cutters? Each of these factors affects how you should approach sharpening.

Pitch: This is the distance between three rivets divided by two. Common pitches are .325″, 3/8″, and .404″. Knowing your pitch is crucial for selecting the correct File-O-Plate.
Gauge: This is the thickness of the drive links that fit into the guide bar groove. Common gauges are .043″, .050″, .058″, and .063″. Again, important for File-O-Plate compatibility.
Cutter Type: Full-chisel chains are designed for fast, clean cuts in softer woods, but they dull quicker. Semi-chisel chains are more durable and better suited for dirty or frozen wood. Understanding your cutter type will help you determine how aggressively to file.

Why this matters for cost: Incorrect filing can lead to premature chain wear, requiring you to replace chains more often. Chains aren’t cheap! I’ve seen guys burn through chains in a matter of weeks because they were filing incorrectly. A new 18-inch chain can easily set you back $30-$50, depending on the brand and type. Understanding your chain and sharpening it correctly is a direct way to save money.

Personal Anecdote: I remember when I first started felling trees, I thought all chains were created equal. I’d just grab whatever was on sale and slap it on my saw. My cuts were slow, the chain would dull quickly, and I was constantly replacing them. It wasn’t until a seasoned logger took me aside and explained the importance of understanding chain types that I started seeing a real difference. Now, I know exactly what chain to use for what type of wood, and I’m saving a significant amount of money on replacements.

2. The Right Tools for the Job: Beyond the File-O-Plate

While the File-O-Plate is your primary sharpening tool, having a few other essentials on hand will make the process smoother and more effective.

Depth Gauge Tool: This is essential for maintaining the correct depth of the rakers (also known as depth gauges or gullets). Rakers control how much wood the cutter takes with each pass.
Flat File: Used for filing down the rakers.
Stump Vise: A portable vise that clamps onto a stump or log, providing a stable platform for sharpening.
Cleaning Brush: Keeping your chain clean of sawdust and debris is crucial for effective filing.

Cost Breakdown:

Depth Gauge Tool: $5 – $15
Flat File: $5 – $10
Stump Vise: $20 – $40
Cleaning Brush: $5 – $10

Total Investment: $35 – $75

Is it worth it? Absolutely. Investing in these tools will not only improve the quality of your sharpening but also extend the life of your chain, saving you money in the long run. Think of it as a preventative maintenance investment. I’ve found that a well-maintained chain cuts faster, requires less effort, and reduces wear and tear on my chainsaw, which translates to fewer repairs and a longer lifespan for the saw itself.

3. Mastering the Filing Angle: The Key to a Sharp Edge

The Carlton File-O-Plate is designed to help you maintain the correct filing angle, but it’s crucial to understand what that angle should be. Generally, you’re aiming for a top plate cutting angle of around 30-35 degrees and a side plate angle of around 60 degrees. The File-O-Plate is designed with these angles in mind, but you still need to pay attention to how you’re holding it.

Consistency is Key: Maintain a consistent angle and pressure with each stroke.
File in One Direction: Always file from the inside of the cutter to the outside.
Count Your Strokes: File each cutter the same number of strokes to ensure they are all the same length.

Why angle matters for cost: An incorrect filing angle can lead to a weak or overly aggressive cutting edge. A weak edge will dull quickly, while an overly aggressive edge can chip or break easily. Both scenarios lead to premature chain wear and increased replacement costs.

Data Point: A study by the Forest Engineering Research Institute of Canada (FERIC) found that proper chain maintenance, including correct filing angles, can increase chain lifespan by up to 50%. That’s a significant saving!

4. Depth Gauge Adjustment: Taming the Rakers

The rakers (depth gauges) control how much wood the cutter takes with each pass. As you sharpen the cutters, they become shorter, and the rakers need to be filed down to maintain the correct relationship. If the rakers are too high, the chain will chatter and cut slowly. If they are too low, the chain will grab and be difficult to control.

Use a Depth Gauge Tool: Place the tool on the chain, and any raker that protrudes above the tool needs to be filed down.
File Evenly: File the rakers down evenly, taking care not to round them off too much.
Check Regularly: Check the raker depth every few sharpenings.

Cost Implications: Neglecting the rakers can put undue stress on your chainsaw engine and bar. A dull chain forces the engine to work harder, leading to increased fuel consumption and potential engine damage. A new chainsaw engine can easily cost hundreds of dollars to replace. I learned this the hard way when I ignored my rakers for too long and ended up burning out my saw’s clutch. The repair bill was a painful reminder of the importance of proper maintenance.

5. Chain Tension: The Goldilocks Zone

Proper chain tension is crucial for both safety and performance. Too loose, and the chain can derail or bind. Too tight, and it can overheat and stretch.

The Sag Test: Lift the chain in the middle of the guide bar. You should be able to pull it out about 1/8 inch.
Adjust as Needed: Adjust the tension as needed, especially when the chain is new. New chains tend to stretch more than older chains.
Check Frequently: Check the tension frequently, especially when cutting different types of wood or in different temperatures.

Cost Savings: A properly tensioned chain reduces friction and wear on the guide bar and sprocket. A worn guide bar can damage the chain, and a worn sprocket can cause the chain to skip or bind. Replacing a guide bar can cost $20-$50, and a new sprocket can cost $10-$30. Maintaining proper chain tension is a simple way to avoid these unnecessary expenses.

Personal Story: I once had a chain snap on me while I was cutting firewood. It was a close call, and I was lucky to escape without injury. The chain snapped because it was too loose and had been rubbing against the guide bar for too long. I learned a valuable lesson that day about the importance of chain tension and safety.

6. Cleaning and Lubrication: The Lifeblood of Your Chain

A clean and well-lubricated chain will cut faster, last longer, and reduce wear on your chainsaw.

Clean Regularly: Use a brush or compressed air to remove sawdust and debris from the chain after each use.
Use the Right Oil: Use a high-quality bar and chain oil designed for chainsaws.
Check the Oiler: Make sure your chainsaw’s oiler is working properly. A lack of lubrication can quickly ruin a chain and damage the guide bar.

Cost Justification: Bar and chain oil is relatively inexpensive, typically costing around $10-$20 per gallon. However, the cost of neglecting lubrication can be significant. A dry chain creates excessive friction, leading to rapid wear and tear on the chain, guide bar, and sprocket. Additionally, a dry chain puts extra strain on the chainsaw engine, potentially leading to costly repairs. I always keep a spare gallon of bar and chain oil on hand, just in case. It’s a small price to pay for peace of mind.

Tip: Consider using a bio-degradable bar and chain oil. It’s better for the environment and often performs just as well as traditional oil.

7. Storage: Protecting Your Investment

Proper storage is often overlooked, but it’s essential for protecting your chain from rust and damage.

Clean and Oil: Clean and oil the chain before storing it.
Store in a Dry Place: Store the chain in a dry place to prevent rust.
Use a Chain Case: Use a chain case or wrap the chain in a cloth to protect it from damage.

Long-Term Cost Savings: Rust is a chain’s worst enemy. It weakens the metal and makes the chain more prone to breakage. A rusted chain is also more difficult to sharpen and will dull more quickly. By properly storing your chain, you can prevent rust and extend its lifespan, saving you money on replacements. I’ve seen chains that were practically brand new ruined by improper storage. It’s a shame to waste money like that.

The Economics of Chainsaw Sharpening: A Data-Driven Approach

Now that we’ve covered the “how,” let’s talk about the “why.” Why bother sharpening your own chains when you can just take them to a professional? The answer, as always, comes down to cost.

Professional Sharpening vs. DIY: A Cost Comparison

Professional Sharpening:

Cost per Sharpening: $10 – $20 (depending on the size and type of chain)
Turnaround Time: Typically 1-3 days
Convenience: Convenient if you don’t have the time or skills to sharpen your own chains.

DIY Sharpening (Using a File-O-Plate):

Initial Investment: $20 – $40 (for the File-O-Plate and other essential tools)
Cost per Sharpening: Minimal (primarily the cost of your time)
Turnaround Time: 10-15 minutes per chain
Convenience: Requires time and skill, but allows you to sharpen your chains whenever and wherever you need to.

Break-Even Analysis:

Let’s assume you sharpen your chain 10 times per year. If you take it to a professional, you’ll spend $100 – $200 per year. If you sharpen it yourself, your initial investment will be paid off within 1-2 years, and you’ll save money in the long run.

Beyond the Numbers:

The cost savings of DIY sharpening are significant, but there are other benefits as well. Sharpening your own chains gives you more control over the quality of the sharpening. You can customize the angles and raker depth to suit your specific needs. Additionally, sharpening your own chains allows you to keep your saw running at peak performance, which can improve your productivity and reduce fatigue.

Case Study: I recently spoke with a small-scale logger who had been taking his chains to a professional for years. He was spending around $300 per year on sharpening. I convinced him to invest in a File-O-Plate and teach himself how to sharpen his own chains. After a few weeks of practice, he was able to sharpen his chains just as well as the professional. He estimated that he was saving around $250 per year, and he was also able to keep his saw running sharper for longer.

The Cost of Dull Chains: A Hidden Expense

Dull chains are not only frustrating, but they can also be expensive.

Increased Fuel Consumption: A dull chain forces the engine to work harder, leading to increased fuel consumption. I’ve seen fuel consumption increase by as much as 20% with a dull chain.
Increased Wear and Tear on the Saw: A dull chain puts extra stress on the engine, bar, and sprocket, leading to increased wear and tear and potential repairs.
Reduced Productivity: A dull chain cuts slower and requires more effort, reducing your productivity.
Increased Risk of Injury: A dull chain is more likely to kick back or bind, increasing the risk of injury.

Quantifying the Costs:

Let’s say you use your chainsaw for 10 hours per week. With a dull chain, your fuel consumption might increase by 20%, costing you an extra $5 per week in fuel. Over the course of a year, that’s an extra $260 in fuel costs. Additionally, the increased wear and tear on your saw could lead to an extra $100 in repair costs. Finally, the reduced productivity could cost you several hours of work per week. All told, a dull chain could easily cost you hundreds of dollars per year.

The Bottom Line:

Keeping your chain sharp is not only important for safety and performance, but it’s also a smart financial decision. Investing in a File-O-Plate and learning how to sharpen your own chains is a simple way to save money and improve your productivity.

Wood Species and Their Impact on Chain Wear and Sharpening Frequency

The type of wood you’re cutting significantly impacts how quickly your chain dulls. Hardwoods, naturally, are tougher on chains than softwoods. But within those categories, there’s a wide range of abrasiveness.

Hardwoods: Oak, maple, hickory, and beech are known for their density and hardness. They require more frequent sharpening and can wear down chains faster. I’ve found that oak, in particular, can be quite abrasive, especially when it’s dry.
Softwoods: Pine, fir, spruce, and cedar are generally easier on chains. However, some softwoods, like pine, can be sappy and gum up the chain, requiring more frequent cleaning.
Exotic Woods: Some exotic hardwoods, like teak and mahogany, can be extremely dense and oily, requiring specialized chains and sharpening techniques.

Data on Wood Density:

The Janka hardness test measures the resistance of wood to indentation. Here are some examples:

Oak (Red): 1290 lbf (pounds-force)
Maple (Hard): 1450 lbf
Pine (Eastern White): 380 lbf
Cedar (Western Red): 350 lbf

As you can see, hardwoods are significantly harder than softwoods, which translates to more wear and tear on your chainsaw chain.

Adapting Your Sharpening Strategy:

Hardwoods: Sharpen more frequently, use a slightly more aggressive filing angle, and consider using a chain with carbide-tipped cutters for increased durability.
Softwoods: Sharpen less frequently, use a less aggressive filing angle, and clean the chain regularly to remove sap and gum.
Dirty Wood: If you’re cutting wood that’s dirty or has bark, sharpen more frequently and clean the chain regularly to prevent abrasive particles from dulling the cutters.

Cost Optimization:

By understanding the properties of the wood you’re cutting and adapting your sharpening strategy accordingly, you can extend the life of your chain and reduce your sharpening costs. For example, if you’re primarily cutting softwoods, you can get away with sharpening less frequently, saving you time and effort. On the other hand, if you’re cutting hardwoods, you’ll need to sharpen more frequently, but you can also invest in a more durable chain that will last longer.

Key Budget Items:

Chains: Chains are a consumable item and will need to be replaced eventually. Factor in the cost of replacement chains based on your usage and the type of wood you’re cutting.
Bar and Chain Oil: Bar and chain oil is essential for lubricating the chain and preventing wear. Budget for a sufficient supply of oil.
Sharpening Supplies: This includes the File-O-Plate, depth gauge tool, flat file, and any other sharpening tools you use.
Guide Bar: The guide bar will eventually wear out and need to be replaced. Budget for a new guide bar every few years.
Sprocket: The sprocket is another wear item that will need to be replaced periodically.
Air Filter: A clean air filter is essential for proper engine performance. Budget for a new air filter every year.
Spark Plug: The spark plug will need to be replaced periodically to ensure proper ignition.
Fuel: Factor in the cost of fuel for your chainsaw.
Repairs: Set aside a contingency fund for unexpected repairs.

Sample Budget:

Here’s a sample budget for a chainsaw used for occasional firewood cutting:

Chains: $50 per year
Bar and Chain Oil: $20 per year
Sharpening Supplies: $10 per year
Guide Bar: $30 every 3 years (or $10 per year)
Sprocket: $20 every 5 years (or $4 per year)
Air Filter: $5 per year
Spark Plug: $5 per year
Fuel: $50 per year
Repairs: $50 per year

Total Annual Budget: $214

Adjusting the Budget:

This is just a sample budget, and you’ll need to adjust it based on your specific usage and needs. If you use your chainsaw more frequently or for more demanding tasks, you’ll need to increase the budget accordingly.

Cost-Saving Tips:

Perform Regular Maintenance: Regular maintenance can prevent costly repairs.
Sharpen Your Own Chains: Sharpening your own chains can save you money on professional sharpening services.
Buy in Bulk: Buy bar and chain oil and other supplies in bulk to save money.
Shop Around for Parts: Compare prices from different suppliers before buying parts.
Consider Used Parts: Consider buying used parts if you’re on a tight budget.

The Art and Science of Drying Firewood: Optimizing for Cost and Efficiency

Seasoning firewood is a crucial step in the firewood preparation process. Properly seasoned firewood burns hotter, cleaner, and is easier to ignite. However, the drying process can take time and requires careful planning.

Understanding Moisture Content:

Freshly cut wood can have a moisture content of 50% or higher. Seasoned firewood should have a moisture content of 20% or less.

Impact of Moisture: High moisture content reduces the heat output of firewood and increases the amount of smoke produced. It also contributes to creosote buildup in chimneys, which can be a fire hazard.
Measuring Moisture Content: You can use a moisture meter to measure the moisture content of firewood. Moisture meters are relatively inexpensive and can be purchased at most hardware stores.

Drying Methods:

Air Drying: Air drying is the most common method of seasoning firewood. It involves stacking the wood in a well-ventilated area and allowing it to dry naturally.
Kiln Drying: Kiln drying is a faster method of seasoning firewood. It involves placing the wood in a kiln and using heat to remove the moisture. Kiln-dried firewood is typically more expensive than air-dried firewood.

Factors Affecting Drying Time:

Wood Species: Softwoods dry faster than hardwoods.
Climate: Warm, dry climates are ideal for seasoning firewood.
Stacking Method: Stacking the wood properly can improve air circulation and speed up the drying process.
Wood Size: Smaller pieces of wood dry faster than larger pieces.

Cost Considerations:

Air Drying: Air drying is the most cost-effective method of seasoning firewood. The primary cost is the time and effort required to stack the wood.
Kiln Drying: Kiln drying is more expensive than air drying, but it is faster and can produce higher-quality firewood.

Optimizing the Drying Process:

Stack the Wood Properly: Stack the wood in a single row with plenty of space between each piece.
Elevate the Wood: Elevate the wood off the ground to improve air circulation.
Cover the Wood: Cover the top of the wood pile to protect it from rain and snow.
Choose a Sunny Location: Choose a sunny location to maximize drying potential.
Allow Sufficient Time: Allow sufficient time for the wood to dry. The drying process can take anywhere from 6 months to 2 years, depending on the wood species and climate.

Calculating Log Volume: Board Feet vs. Cords – A Practical Guide

Understanding how to calculate log volume is essential for accurately estimating the amount of wood you have and determining its value. There are two primary units of measurement used for logs: board feet and cords.

Board Feet:

A board foot is a unit of volume equal to 144 cubic inches. It is typically used to measure the volume of sawn lumber.

Calculating Board Feet: There are several formulas for calculating board feet, but one of the most common is the Doyle Log Scale:
- Board Feet = (D – 4)^2 * L / 16
- Where:
  - D = Diameter of the log in inches
  - L = Length of the log in feet
Example: A log that is 16 inches in diameter and 10 feet long would contain approximately 144 board feet.

Cords:

A cord is a unit of volume equal to 128 cubic feet. It is typically used to measure the volume of firewood.

Calculating Cords: To calculate the number of cords in a pile of firewood, measure the length, width, and height of the pile in feet. Multiply these dimensions together to get the volume in cubic feet. Then, divide the volume by 128 to get the number of cords.
- Cords = L * W * H / 128
- Where:
  - L = Length of the pile in feet
  - W = Width of the pile in feet
  - H = Height of the pile in feet
Example: A pile of firewood that is 8 feet long, 4 feet wide, and 4 feet high would contain one cord.

Converting Between Board Feet and Cords:

There is no precise conversion factor between board feet and cords, as the number of board feet in a cord can vary depending on the size and shape of the logs. However, a general estimate is that one cord of firewood contains approximately 500 board feet.

Cost Implications:

Understanding how to calculate log volume is essential for accurately pricing timber and firewood. When buying or selling logs, it’s important to agree on a unit of measurement and a method for calculating volume.
