The world of chainsaw chains can be a labyrinth of numbers, angles, and specialized designs. Among these, the skip tooth chain stands out, not just for its distinctive appearance, but for the unique advantages it offers to both seasoned arborists and weekend woodcutters. I’ve spent countless hours in the woods, felling trees and processing timber, and I can tell you firsthand, understanding the nuances of different chain types can dramatically impact your efficiency and the quality of your work. This article dives deep into the skip tooth chain, revealing five critical arborist tips that you probably didn’t know, and that will help you make informed decisions about when and how to use this powerful tool. We’ll also explore the costs associated with using skip tooth chains, and how to budget effectively for your wood processing and firewood preparation projects.

1. What is a Skip Tooth Chain and Why Should You Care?

A skip tooth chain, also known as a full skip chain, is characterized by its wider spacing between cutting teeth. Unlike a standard chain where every link has a cutting tooth, a skip tooth chain has a drive link without a corresponding cutter in between each cutting link. This seemingly small alteration has a profound impact on the chain’s performance.

• Increased Cutting Speed: The reduced number of teeth means less resistance as the chain moves through the wood. This translates to faster cutting, particularly in softer woods.

• Better Chip Clearance: The wider gaps between teeth allow for more efficient removal of wood chips. This is crucial when cutting large diameter logs, where chip build-up can significantly slow down your progress.

• Reduced Power Requirement: Because there are fewer teeth engaging with the wood at any given time, the chainsaw requires less power to operate. This can be beneficial when using smaller or less powerful saws.

• Aggressive Cutting: Skip tooth chains are known for their aggressive cutting action. They tend to “bite” into the wood more readily, making them ideal for felling and bucking large trees.

2. Arborist Tip #1: Identifying the Ideal Wood Types for Skip Tooth Chains

Not all wood is created equal, and neither are chainsaw chains. Skip tooth chains excel in specific types of wood.

• Softwoods: Pine, fir, cedar, and spruce are prime candidates for skip tooth chains. These woods are relatively easy to cut, and the aggressive cutting action of the skip tooth chain can significantly speed up your work. I’ve personally found that when processing large quantities of pine for firewood, switching to a skip tooth chain can cut my time in half.

• Large Diameter Logs: When dealing with logs exceeding 12 inches in diameter, the improved chip clearance of a skip tooth chain becomes invaluable. I remember one particularly challenging job where I was felling old-growth redwood. The sheer volume of chips produced by those massive trees would have bogged down a standard chain, but the skip tooth chain kept things moving smoothly.

• Avoid Hardwoods (Generally): While skip tooth chains can cut hardwoods like oak, maple, and hickory, they are not the optimal choice. Hardwoods are denser and require more precise cutting. The aggressive nature of a skip tooth chain can lead to rough cuts and increased wear on the chain.

3. Arborist Tip #2: Understanding the Trade-offs: Aggression vs. Finish

The skip tooth chain’s aggressive cutting action comes with a trade-off: a less refined finish.

• Rougher Cuts: The wider spacing between teeth means that the cut surface will be rougher compared to a standard chain. This is generally not an issue for felling or bucking, but it can be problematic if you’re aiming for a clean, smooth cut for woodworking or milling.

• Increased Kickback Risk: The aggressive “bite” of a skip tooth chain can increase the risk of kickback, especially for inexperienced users. Always use proper safety gear and techniques when operating a chainsaw, and be extra cautious when using a skip tooth chain.

• Chain Maintenance is Key: Because skip tooth chains are subjected to more stress, regular maintenance is crucial. Sharpening the chain frequently and ensuring proper lubrication will help prolong its lifespan and maintain its performance. I’ve found that using a high-quality bar and chain oil can make a significant difference in the longevity of my chains.

4. Arborist Tip #3: Matching the Chain to Your Chainsaw’s Power

One of the biggest mistakes I see people make is mismatching the chain type to their chainsaw’s power. A skip tooth chain can actually benefit smaller chainsaws.

• Smaller Saws, Big Impact: A smaller chainsaw (30-45cc engine) might struggle to pull a standard chain through large diameter logs. The reduced power requirement of a skip tooth chain can alleviate this issue, allowing you to cut larger logs with a smaller saw. I’ve used this trick countless times when working in remote areas where I couldn’t bring my larger saws.

• Larger Saws, More Speed: On larger chainsaws (50cc+ engine), a skip tooth chain can unleash even more cutting power. The saw can spin the chain faster, resulting in even quicker cuts.

• Always Consult Your Manual: Before switching to a skip tooth chain, consult your chainsaw’s manual to ensure compatibility. Some chainsaws are not designed to handle the aggressive cutting action of a skip tooth chain.

5. Arborist Tip #4: Sharpening Skip Tooth Chains: A Different Approach

Sharpening a skip tooth chain requires a slightly different approach compared to a standard chain.

• Consistent Angle is Key: Maintaining a consistent sharpening angle is crucial for optimal performance. Use a chainsaw file guide to ensure that you’re sharpening each tooth at the correct angle.

• Sharpening Frequency: Because skip tooth chains are subjected to more stress, they tend to dull more quickly. Sharpen your chain frequently, ideally after every tank of gas.

• Pay Attention to Depth Gauges: The depth gauges (also known as rakers) control how much wood each tooth can cut. If the depth gauges are too high, the chain will cut slowly. If they are too low, the chain will be too aggressive and prone to kickback. Use a depth gauge tool to maintain the correct height.

• Professional Sharpening: If you’re not comfortable sharpening your own chains, consider taking them to a professional. A professional sharpener can ensure that your chain is properly sharpened and ready for action. I’ve used professional sharpening services for years, and it’s always been a worthwhile investment.

6. Arborist Tip #5: Knowing When Not to Use a Skip Tooth Chain

While skip tooth chains are excellent for specific applications, they are not a universal solution.

• Precision Cuts: As mentioned earlier, skip tooth chains are not ideal for precision cuts. If you’re building furniture or doing other woodworking projects where a clean, smooth cut is essential, stick with a standard chain.

• Hardwoods Requiring Finesse: While a skip tooth can cut hardwoods, you may find it less efficient and more prone to vibration than a standard chain. If you are cutting hardwoods for milling, or other applications where a smooth cut is required, a standard chain is a better option.

• Small Diameter Trees and Limbs: When pruning small trees or limbing, a skip tooth chain can be overkill. The aggressive cutting action can make it difficult to control the saw, increasing the risk of injury. A standard chain provides more control and a cleaner cut in these situations.

7. Cost Analysis: Skip Tooth Chains vs. Standard Chains

Understanding the cost implications of using skip tooth chains is crucial for effective budgeting.

• Initial Purchase Price: Skip tooth chains typically cost slightly more than standard chains. Expect to pay around $20-$40 for a high-quality skip tooth chain, depending on the length and gauge.

• Chain Longevity: Due to the increased stress on each tooth, skip tooth chains may wear out slightly faster than standard chains. However, this can be mitigated by proper maintenance and sharpening.

• Fuel Consumption: Because skip tooth chains require less power, they can potentially reduce fuel consumption. This can result in significant savings over time, especially if you’re using your chainsaw frequently. I’ve tracked my fuel consumption over several months, and I’ve consistently seen a 10-15% reduction when using a skip tooth chain on softwood projects.

• Labor Costs: The increased cutting speed of a skip tooth chain can translate to reduced labor costs, particularly for large-scale logging or firewood preparation projects. I’ve seen crews cut their processing time by as much as 20% simply by switching to skip tooth chains.

8. Budgeting for Chainsaw Chains and Maintenance

Creating a realistic budget for chainsaw chains and maintenance is essential for managing your wood processing costs.

• Estimate Chain Usage: Based on the types of wood you’ll be cutting and the frequency of use, estimate how many chains you’ll need per year. A good rule of thumb is to have at least two chains per chainsaw, allowing you to rotate them and extend their lifespan.

• Factor in Sharpening Costs: If you’re sharpening your own chains, factor in the cost of files, file guides, and other sharpening tools. If you’re using a professional sharpening service, budget for the cost per chain. Expect to pay around $10-$20 per chain for professional sharpening.

• Consider Bar and Chain Oil: Using a high-quality bar and chain oil is crucial for prolonging the lifespan of your chains and your chainsaw. Budget for a sufficient supply of oil based on your estimated usage. I typically go through about a gallon of oil per month during peak cutting season.

• Preventive Maintenance: Regular preventive maintenance, such as cleaning the chainsaw, checking the spark plug, and inspecting the air filter, can help prevent costly repairs down the road. Set aside a small amount of money each month for preventive maintenance.

• Contingency Fund: Always include a contingency fund in your budget to cover unexpected repairs or replacements. Chainsaws can be temperamental, and you never know when a part might break down.

9. Data-Backed Insights: Timber Prices, Equipment Rental, and Fuelwood Rates

Understanding current industry benchmarks can help you make informed decisions about your wood processing projects.

• Timber Prices: Timber prices vary significantly depending on the species, quality, and location. According to the Forest Resources Association, the average price for standing timber in the United States ranges from $20 to $100 per thousand board feet (MBF) for softwoods and $50 to $300 per MBF for hardwoods.

• Equipment Rental: Renting logging equipment, such as skidders and loaders, can be a cost-effective option for short-term projects. Rental rates vary depending on the equipment type and location. Expect to pay around $500-$1,000 per day for a skidder and $300-$800 per day for a loader.

• Fuelwood Market Rates: The price of firewood varies depending on the region, species, and quantity. According to the U.S. Energy Information Administration, the average price for a cord of firewood in the United States ranges from $150 to $400.

10. Case Study: Optimizing Firewood Preparation Costs with Skip Tooth Chains

Let’s consider a case study to illustrate how skip tooth chains can help optimize firewood preparation costs.

• Scenario: A small-scale firewood supplier processes 100 cords of firewood per year. They use a 45cc chainsaw with a 16-inch bar and currently use a standard chain.

• Analysis: By switching to a skip tooth chain, the supplier can potentially reduce their cutting time by 15%. This translates to a savings of 15 hours of labor per year. At a labor rate of $20 per hour, this results in a savings of $300 per year.

• Additional Savings: The reduced power requirement of the skip tooth chain can also lead to a savings of 10% on fuel costs. Assuming the supplier spends $500 per year on fuel, this results in an additional savings of $50 per year.

• Total Savings: By switching to a skip tooth chain, the supplier can potentially save $350 per year.

11. Cost Optimization Tips for Wood Processing and Firewood Preparation

Here are some practical tips for optimizing your wood processing and firewood preparation costs.

12. Calculating Log Volume: Board Feet and Cords

Understanding how to calculate log volume is essential for accurately estimating timber yields and firewood quantities.

• Board Feet: A board foot is a unit of volume equal to 144 cubic inches. The formula for calculating the board feet of a log is:

  • Board Feet = (Length in Feet x Diameter in Inches x Diameter in Inches) / 144

• Cords: A cord is a unit of volume equal to 128 cubic feet. A standard cord of firewood is typically stacked 4 feet high, 4 feet wide, and 8 feet long.

• Estimating Cordwood from Logs: Estimating the number of cords you can get from a given volume of logs is more complex, as it depends on the log’s diameter, straightness, and the efficiency of your splitting process. However, a rough estimate is that you can get approximately 2-3 cords of firewood per thousand board feet of logs.

13. Estimating Drying Time Based on Moisture Content

Properly drying firewood is crucial for efficient burning. The drying time depends on several factors, including the wood species, the size of the pieces, and the climate.

• Moisture Content: Freshly cut wood typically has a moisture content of 50% or higher. For optimal burning, firewood should be dried to a moisture content of 20% or less.

• Drying Time: In a dry, sunny climate, firewood can dry in as little as six months. In a humid climate, it may take a year or more.

• Measuring Moisture Content: You can use a moisture meter to measure the moisture content of your firewood.

• Improving Drying Time: Stacking firewood in a sunny, well-ventilated location can significantly reduce drying time. Covering the top of the stack with a tarp can also help prevent rain from soaking the wood.
