How to Make Wood Shakes (5 Pro Tips for Perfect Splits)
The art of splitting wood shakes, those rustic and charming roofing materials, is a skill passed down through generations. While the technique itself is relatively straightforward, achieving perfect splits consistently requires a blend of experience, understanding of wood properties, and a keen eye for detail. However, beyond the satisfying thwack of the froe and the satisfying crack of the wood, lies a world of measurable metrics that can elevate your shake-making from a hobby to a truly efficient and profitable endeavor. These metrics, often overlooked, are the key to optimizing your process, reducing waste, and ensuring a high-quality product.
How to Make Wood Shakes (5 Pro Tips for Perfect Splits): Unveiling the Metrics for Success
1. Moisture Content: The Foundation of Quality Splits
Definition
Moisture content (MC) refers to the amount of water present in the wood, expressed as a percentage of the wood’s oven-dry weight. It’s a critical factor influencing the ease of splitting, the stability of the finished shakes, and their resistance to decay.
Why It’s Important
Wood that’s too wet is difficult to split cleanly, leading to ragged edges and inconsistent thicknesses. Wood that’s too dry becomes brittle and prone to cracking, resulting in waste and lower-quality shakes. The ideal moisture content for splitting wood shakes typically falls within a specific range, generally between 20% and 30%. This range allows for clean splits while minimizing the risk of excessive shrinkage or warping as the shakes dry.
How to Interpret It
I use a pin-type moisture meter to accurately measure the MC of my wood. Here’s how I interpret the readings:
- Below 20%: Wood is too dry. Splitting will be difficult, and the shakes are likely to crack. I’ll often re-wet the wood by spraying it with water and allowing it to soak for a few days.
- 20% – 30%: Ideal moisture content. The wood should split easily and cleanly.
- Above 30%: Wood is too wet. Splitting will be messy, and the shakes will be prone to mold and decay if not properly dried. I’ll allow the wood to air-dry in a well-ventilated area before splitting. Example: I once received a shipment of cedar logs that measured 35% MC. Attempting to split them resulted in uneven shakes and a significant amount of splintering. After allowing the logs to air-dry for two weeks, the MC dropped to 25%, and the splitting process became significantly easier and more efficient.
How It Relates to Other Metrics
Moisture content directly impacts yield rate (see metric #2) and drying time (see metric #5). Wood that’s split at the ideal MC will result in a higher yield of usable shakes and will dry more evenly, reducing the risk of warping or cracking.
2. Yield Rate: Maximizing Resource Utilization
Definition
Yield rate is the percentage of usable wood shakes produced from a given volume of raw material (logs or bolts). It’s a measure of efficiency in the splitting process and reflects how effectively you’re utilizing your resources.
Why It’s Important
Tracking yield rate helps you identify areas for improvement in your splitting technique, wood selection, and overall process. A low yield rate indicates that you’re wasting valuable wood, which translates to increased costs and reduced profitability.
How to Interpret It
I calculate yield rate by dividing the volume of usable shakes produced by the volume of raw material used, then multiplying by 100 to express it as a percentage. For example, if I start with 1 cubic meter of cedar logs and produce 0.6 cubic meters of usable shakes, my yield rate is 60%.
- Below 50%: Low yield rate. Indicates significant waste. Investigate splitting technique, wood quality, and equipment.
- 50% – 70%: Average yield rate. Room for improvement.
- Above 70%: High yield rate. Excellent resource utilization.
Example: Early in my shake-making career, my yield rate was consistently around 45%. I realized I was losing a lot of wood due to improper splitting technique and using logs with excessive knots. By improving my technique and carefully selecting logs, I was able to increase my yield rate to over 65%, significantly boosting my profitability.
How It Relates to Other Metrics
Yield rate is closely linked to moisture content (see metric #1), splitting time (see metric #3), and waste reduction (see metric #4). Maintaining the optimal moisture content, improving splitting efficiency, and minimizing waste will all contribute to a higher yield rate.
3. Splitting Time: Optimizing Efficiency
Definition
Splitting time refers to the amount of time it takes to split a specific volume of wood into shakes. It’s a measure of productivity and reflects your efficiency in the splitting process.
Why It’s Important
Tracking splitting time helps you identify bottlenecks in your workflow and optimize your process for maximum efficiency. Reducing splitting time translates to increased output and reduced labor costs.
How to Interpret It
I track splitting time by measuring the time it takes to split a standard unit of wood, such as a cubic meter or a cord. I use a stopwatch to record the time for each batch and then calculate the average splitting time.
- High splitting time: Indicates inefficiencies in the process. Investigate splitting technique, tool sharpness, and wood quality.
- Low splitting time: Indicates a highly efficient process.
Example: I noticed that my splitting time was significantly higher when using a dull froe. After sharpening my froe, my splitting time decreased by approximately 20%, allowing me to produce more shakes in the same amount of time.
How It Relates to Other Metrics
Splitting time is influenced by moisture content (see metric #1), tool maintenance (see metric #4), and splitting technique. Maintaining sharp tools, optimizing moisture content, and improving your splitting technique will all contribute to a lower splitting time.
4. Waste Reduction: Minimizing Loss, Maximizing Profit
Definition
Waste reduction refers to the strategies and practices employed to minimize the amount of wood that’s discarded during the shake-making process. It’s a measure of resourcefulness and reflects your commitment to sustainability and cost-effectiveness.
Why It’s Important
Minimizing waste reduces the amount of raw material required to produce a given quantity of shakes, which translates to lower costs and increased profitability. It also promotes sustainable forestry practices by ensuring that every part of the log is utilized effectively.
How to Interpret It
I track waste by measuring the volume of wood that’s discarded during the splitting process. This includes wood that’s too knotted, cracked, or otherwise unsuitable for making shakes. I then calculate the waste percentage by dividing the volume of waste by the volume of raw material used, then multiplying by 100.
- High waste percentage: Indicates significant inefficiency. Investigate wood selection, splitting technique, and tool maintenance.
- Low waste percentage: Indicates effective waste reduction strategies.
Example: I used to discard a significant amount of wood due to knots and imperfections. However, I discovered that I could salvage some of this wood by using it to make smaller shakes or shingles. By implementing this waste reduction strategy, I was able to reduce my waste percentage by approximately 15%. I even began selling the remaining waste as kindling, generating additional revenue.
How It Relates to Other Metrics
Waste reduction is closely linked to yield rate (see metric #2), splitting time (see metric #3), and moisture content (see metric #1). Improving your splitting technique, selecting high-quality wood, and maintaining the optimal moisture content will all contribute to a lower waste percentage.
Tool Maintenance: A Crucial Element of Waste Reduction
Proper tool maintenance is vital for waste reduction. A dull froe or axe will lead to ragged splits and increased waste. Regularly sharpening and maintaining your tools will ensure clean, efficient cuts, minimizing the amount of wood that’s unusable.
Wood Selection: Choosing the Right Material
Selecting the right type of wood and carefully inspecting logs for defects is another key factor in waste reduction. Choosing straight-grained, knot-free wood will significantly reduce the amount of waste generated during the splitting process.
Splitting Technique: Mastering the Art
Mastering the proper splitting technique is essential for minimizing waste. Learning to read the grain of the wood and using the froe and mallet effectively will result in cleaner splits and less waste.
5. Drying Time: Ensuring Stability and Longevity
Definition
Drying time refers to the amount of time it takes for freshly split shakes to reach the desired moisture content for installation or sale. It’s a critical factor influencing the stability and longevity of the finished product.
Why It’s Important
Shakes that are installed before they’re properly dried are prone to shrinkage, warping, and cracking, which can compromise their structural integrity and aesthetic appeal. Tracking drying time helps you ensure that your shakes are properly seasoned before they’re used.
How to Interpret It
I track drying time by measuring the moisture content of the shakes periodically as they dry. The desired moisture content for installation typically falls within a range of 12% to 15%. I use a moisture meter to monitor the MC and record the time it takes to reach the target range.
- Long drying time: Indicates poor drying conditions. Improve ventilation and reduce humidity.
- Short drying time: Indicates ideal drying conditions.
Example: I initially stacked my shakes in a damp, shaded area, which resulted in a very long drying time and some mold growth. After moving the shakes to a well-ventilated, sunny location, the drying time decreased significantly, and I eliminated the mold problem.
How It Relates to Other Metrics
Drying time is influenced by moisture content (see metric #1), stacking method, and environmental conditions. Splitting the wood at the optimal moisture content, stacking the shakes properly to allow for good air circulation, and providing adequate ventilation will all contribute to a shorter drying time.
Stacking Methods: Optimizing Airflow
The way you stack your shakes can significantly impact drying time. Stacking them loosely with adequate spacing between each shake allows for good air circulation, which speeds up the drying process.
Environmental Conditions: Harnessing the Power of Nature
Environmental conditions, such as temperature, humidity, and sunlight, play a crucial role in drying time. Drying shakes in a sunny, well-ventilated location will significantly reduce drying time compared to drying them in a damp, shaded area.
