Understanding Cherry Wood: The Root of the Problem

Before we get into the how, let’s tackle the why. Cherry wood, scientifically known as Prunus serotina, is prized for its rich color, smooth grain, and excellent workability. But these qualities come with a catch: cherry is prone to splitting, especially in the bark.

The Cellular Structure:

Cherry wood has a relatively fine, uniform cellular structure. This makes it easy to work with, but it also means that moisture can move through it quickly. This rapid moisture movement, especially during drying, is a major culprit behind splitting. Think of it like a sponge: if you squeeze it too hard too fast, it tears.

Moisture Content and Stress:

Green cherry wood can have a moisture content of over 80%. As it dries, the outer layers shrink faster than the inner layers. This difference in shrinkage creates internal stress, which often manifests as splits in the bark. The bark, being less flexible than the wood, is particularly vulnerable.

Data Point: According to the USDA Forest Service, the ideal moisture content for woodworking is between 6% and 8%. Getting cherry down to this level without inducing splits requires careful control of the drying process.

My Personal Experience:

I remember the first time I tried to dry a large cherry log without taking proper precautions. I stacked it in my shed, figuring it would be fine. A few weeks later, I went back to find splits running the entire length of the log. It was a painful lesson, but it taught me the importance of understanding the wood’s behavior.

Preventative Measures: Stopping Splits Before They Start

The best way to deal with split bark is to prevent it in the first place. This starts from the moment you fell the tree and continues through the initial stages of processing.

1. Felling Techniques:

• Avoid Felling in Extreme Weather: Felling trees during hot, dry weather or freezing temperatures increases the risk of splitting. The rapid temperature changes put extra stress on the wood. Aim for felling in the spring or fall when temperatures are more moderate.
• Proper Undercut and Back Cut: Use a proper felling technique with a deep undercut and a precise back cut. This helps control the direction of the fall and minimizes impact. A hinge of sufficient width will help prevent the tree from twisting and tearing as it falls.
• Felling Wedges: Employ felling wedges to gently guide the tree’s fall. This prevents the tree from slamming into the ground, which can cause significant splitting. I prefer using plastic or aluminum wedges, as they are less likely to damage the chainsaw chain if accidentally contacted.

2. Bucking Strategies:

• Cut Logs to Manageable Lengths: Bucking logs into shorter lengths reduces the overall stress on the wood. Shorter logs are less likely to develop long splits. I typically buck cherry logs into lengths of 4-8 feet, depending on the intended use.
• Relieve Tension Cuts: Before making the final bucking cut, make a shallow relief cut on the opposite side of the log. This helps relieve tension and prevents the wood from pinching the saw blade, which can lead to splitting.
• Support the Log: Ensure the log is properly supported during bucking. Use log supports or a log jack to prevent the log from sagging or rolling. This reduces the risk of splits and makes the job safer.

3. Initial Sealing:

• End-Grain Sealer: Apply an end-grain sealer immediately after bucking. This slows down the rate of moisture loss from the ends of the logs, which is where most splits originate. I use a commercial end-grain sealer, but you can also use latex paint or even melted wax in a pinch.
• Whole-Log Sealing (Optional): For particularly valuable or sensitive cherry logs, consider sealing the entire log with a breathable sealant. This helps to control the overall drying rate and minimize stress.

Expert Insight: According to Dr. Gene Wengert, a renowned wood drying expert, end-grain sealing can reduce end checking (splits) by up to 80%.

My Personal Experience:

I once had a beautiful cherry log that I was determined to preserve. I meticulously sealed the ends, but I neglected to seal a small knot hole on the side. Sure enough, a split developed right at that knot hole. Lesson learned: even small imperfections can become weak points.

Tool Selection: Choosing the Right Weapons

Having the right tools can make a world of difference when working with cherry wood. Here’s a breakdown of the tools I rely on to minimize splitting.

1. Chainsaws:

• Sharp Chain: A sharp chainsaw chain is essential for clean, efficient cuts. A dull chain will tear the wood fibers, increasing the risk of splitting. I sharpen my chain before every major cutting session.
• Low-Kickback Chain: For safety, I recommend using a low-kickback chain, especially if you’re a beginner. Kickback can be dangerous and can also cause damage to the wood.
• Appropriate Bar Length: Choose a bar length that is appropriate for the size of the logs you’re working with. A bar that is too short will make the job difficult, while a bar that is too long can be unwieldy.

2. Wedges:

• Plastic or Aluminum Wedges: As mentioned earlier, I prefer plastic or aluminum felling wedges. They are less likely to damage the chainsaw chain if accidentally contacted.
• Steel Splitting Wedges: For splitting logs, I use steel splitting wedges. These are designed to be driven into the wood with a sledgehammer. Choose a wedge with a wide, sharp edge for maximum splitting power.
• Feather and Wedge (Shims and Wedges): For controlled splitting, particularly when dealing with highly figured or valuable cherry, consider using feather and wedge sets. These are inserted into a drilled line and gently tapped to create a precise split.

3. Splitting Axes and Mauls:

• Splitting Axe: A splitting axe is designed for splitting smaller logs. It has a wide, heavy head that delivers a powerful blow.
• Splitting Maul: A splitting maul is a heavier version of the splitting axe, designed for splitting larger, more difficult logs. I prefer a maul with a fiberglass handle for its durability and shock absorption.
• Hydraulic Log Splitter: For high-volume splitting, or for those with physical limitations, a hydraulic log splitter is a great investment. These machines can split even the toughest logs with ease.

4. Moisture Meter:

• Pin-Type Moisture Meter: A pin-type moisture meter measures the moisture content of wood by inserting two pins into the wood. These meters are relatively inexpensive and easy to use.
• Pinless Moisture Meter: A pinless moisture meter uses radio waves to measure the moisture content of wood without penetrating the surface. These meters are more expensive but are less likely to damage the wood.

My Personal Experience:

I used to think that any old axe would do for splitting firewood. But after struggling with a dull, poorly balanced axe for years, I finally invested in a quality splitting maul. The difference was night and day. It made the job faster, easier, and safer.

Drying Strategies: The Art of Patience

Drying cherry wood is a marathon, not a sprint. The key is to slow down the process to minimize stress and prevent splits.

1. Air Drying:

• Proper Stacking: Stack the wood in a well-ventilated area, away from direct sunlight and rain. Use stickers (small strips of wood) to separate the layers of wood, allowing air to circulate freely.
• Sticker Spacing: The spacing between stickers is crucial. I typically use stickers that are 1 inch thick and place them every 12-18 inches.
• End Coating: Ensure the ends of the boards are coated with an end-grain sealer to prevent rapid moisture loss.
• Weighting: Weighting the top layer of the stack with concrete blocks or other heavy objects can help prevent warping.

Data Point: Air drying cherry wood can take anywhere from 6 months to 2 years, depending on the thickness of the wood and the climate.

2. Kiln Drying:

• Professional Kiln: The best way to kiln dry cherry wood is to use a professional kiln. These kilns are designed to control the temperature and humidity, ensuring a consistent and even drying process.
• DIY Kiln (Advanced): If you’re feeling ambitious, you can build your own solar kiln or dehumidification kiln. However, this requires a significant investment of time and resources.

3. Monitoring Moisture Content:

• Regular Checks: Use a moisture meter to regularly check the moisture content of the wood. This will help you track the drying progress and identify any potential problems.
• Target Moisture Content: Aim for a moisture content of 6-8% for woodworking and 15-20% for firewood.

4. Dealing with Existing Splits:

• Butterfly Joints: For small splits, you can use butterfly joints (also known as dovetail keys) to reinforce the wood and prevent the split from spreading.
• Epoxy Resin: Epoxy resin can be used to fill larger splits and stabilize the wood. Choose a clear epoxy for a natural look, or add pigment to match the color of the wood.
• Embrace the Character: Sometimes, the best approach is to embrace the natural character of the wood. Use the splits to create unique design features in your projects.

My Personal Experience:

I once tried to speed up the drying process by placing a fan directly on a stack of cherry boards. The result was disastrous. The boards dried unevenly, and several of them developed severe warping and splitting.

Salvage Techniques: Making the Most of Damaged Wood

Even with the best preventative measures, splits can still occur. But don’t despair! There are several techniques you can use to salvage damaged wood and minimize waste.

1. Cutting Around Splits:

• Strategic Cuts: Carefully plan your cuts to avoid the splits. This may require using smaller pieces of wood than you originally intended, but it’s better than throwing the whole piece away.
• Template Routing: Use templates to guide your cuts and ensure consistent shapes. This is particularly useful for making smaller items like boxes or cutting boards.

2. Filling Splits with Resin:

• Epoxy Resin: As mentioned earlier, epoxy resin can be used to fill splits and stabilize the wood. Choose a resin that is specifically designed for woodworking.
• Colored Resin: Add pigment to the resin to create a contrasting color. This can create a striking visual effect.
• Inlay: Fill the splits with inlay materials like turquoise, metal, or other types of wood. This can add a unique and artistic touch to your projects.

3. Using Splits for Decorative Purposes:

• Rustic Furniture: Embrace the rustic look by using wood with natural splits and imperfections to create furniture. This can add character and charm to your home.
• Firewood Art: Use split pieces of wood to create decorative art pieces for your fireplace or wood stove.

4. Making Small Items:

• Cutting Boards: Small pieces of wood with minor splits can be used to make cutting boards. The splits can be filled with resin or left as natural features.
• Boxes and Trays: Smaller items like boxes and trays can be made from salvaged wood.
• Knife Handles: Wood with interesting grain patterns and minor splits can be used to make unique knife handles.

Original Research Findings:

I conducted a small-scale experiment comparing the strength of cherry wood with and without epoxy-filled splits. I found that the epoxy-filled splits significantly increased the wood’s resistance to bending and breaking. This suggests that epoxy resin can be an effective way to reinforce damaged wood.

My Personal Experience:

I once had a beautiful cherry slab with a large split running down the middle. I was about to give up on it, but then I decided to try filling the split with blue epoxy resin. The result was stunning. The blue resin created a striking contrast with the red cherry wood, and the slab became a unique and eye-catching piece of furniture.
