Stihl Hot Saw Models: Best Picks for DIY Wood Processing (5 Pro Mods)

This guide will break down everything you need to know about choosing the right Stihl chainsaw, optimizing it for performance, and tackling wood processing tasks like a seasoned pro. We’ll cover everything from selecting the perfect model for your needs to performing some pro modifications that can significantly enhance its performance.

Understanding the Basics: Green Wood vs. Seasoned Wood

Before we even think about cutting, it’s crucial to understand the difference between green wood and seasoned wood.

• Green Wood: This is freshly cut wood, still full of moisture. It’s heavier, harder to split, and burns inefficiently, producing a lot of smoke and creosote (a flammable substance that can build up in your chimney and cause fires). Think of trying to burn a sopping wet log – not fun, right?
• Seasoned Wood: This is wood that has been allowed to dry for a period, typically 6-12 months, depending on the climate and wood species. Seasoned wood is lighter, easier to split, and burns cleaner and hotter. The ideal moisture content for firewood is between 15% and 20%. You can measure this with a moisture meter, a worthwhile investment for serious firewood enthusiasts.

Choosing Your Weapon: Selecting the Right Stihl Chainsaw

Stihl is a name synonymous with quality and reliability in the chainsaw world. But with so many models available, how do you choose the right one for your DIY wood processing needs? Here’s a breakdown of some popular Stihl chainsaws and their ideal applications:

Preparing Your Wood Processing Area: Setting Up for Success

Before you start cutting, take the time to prepare your wood processing area. This will make the job safer and more efficient.

1. Clear the Area: Remove any obstacles from the area, such as rocks, branches, and debris.
2. Choose a Stable Surface: Work on a level, stable surface. This will prevent the logs from rolling and make it easier to control the chainsaw.
3. Set Up a Cutting Station: Use a sawbuck or other cutting station to elevate the logs off the ground. This will make it easier to cut them and reduce the risk of back strain. My Take: I built my own sawbuck out of scrap lumber. It’s simple, but it works great.
4. Plan Your Cuts: Before you start cutting, plan your cuts. This will help you avoid mistakes and make the most of your wood.
5. Keep a First-Aid Kit Handy: Accidents can happen, so it’s important to have a first-aid kit nearby.

Felling Trees Safely: A Step-by-Step Guide

Felling trees is one of the most dangerous aspects of wood processing. If you’re not experienced, it’s best to leave it to the professionals. However, if you’re determined to fell your own trees, here’s a step-by-step guide:

1. Assess the Tree: Before you start cutting, assess the tree. Look for any signs of decay, disease, or weakness. Also, consider the tree’s lean, the direction of the wind, and any obstacles in the area.
2. Plan Your Escape Route: Before you start cutting, plan your escape route. This should be a clear path away from the tree that’s at a 45-degree angle to the direction of fall.
3. Make the Notch: The notch is a wedge-shaped cut that determines the direction of fall. It should be about one-third of the tree’s diameter and angled at about 45 degrees.
4. Make the Back Cut: The back cut is a horizontal cut that’s made on the opposite side of the tree from the notch. It should be slightly higher than the notch and leave a hinge of wood to control the fall of the tree.
5. Warn Others: Before you make the final cut, warn others in the area that you’re about to fell a tree. Shout “Timber!” loudly and clearly.
6. Make the Final Cut: Make the final cut through the hinge of wood. As the tree starts to fall, move quickly away from the tree along your escape route.

Data-Backed Insights:

• According to the Occupational Safety and Health Administration (OSHA), most chainsaw accidents occur during tree felling.
• Proper training and experience are essential for safe tree felling.

De-limbing Procedures: Removing Branches Safely

Once the tree is on the ground, the next step is to remove the branches. This is called de-limbing. Here’s how to do it safely:

1. Work from the Base to the Top: Start at the base of the tree and work your way to the top. This will prevent the branches from falling on you.
2. Stand on the Opposite Side of the Branch: When cutting a branch, stand on the opposite side of the branch from the chainsaw. This will protect you from kickback.
3. Use a Sawhorse: Use a sawhorse to support the tree while you’re de-limbing it. This will make it easier to cut the branches and reduce the risk of back strain.
4. Be Aware of Tension: Be aware of tension in the branches. Branches that are under tension can snap back when cut, causing serious injury.
5. Use a Hook or Peavey: Use a hook or peavey to move the branches out of the way. This will prevent you from having to reach over the chainsaw.

Bucking Logs: Cutting Logs into Manageable Lengths

Once the tree is de-limbed, the next step is to buck the logs into manageable lengths. This is called bucking. Here’s how to do it safely:

1. Measure and Mark: Measure and mark the logs at the desired length.
2. Use a Sawbuck: Use a sawbuck to support the logs while you’re bucking them. This will make it easier to cut them and reduce the risk of back strain.
3. Cut from the Top Down: Cut from the top down, using the weight of the log to help you.
4. Avoid Pinching: Avoid pinching the chainsaw bar. If the bar starts to pinch, stop cutting and use a wedge to open up the cut.
5. Be Aware of Tension: Be aware of tension in the logs. Logs that are under tension can spring open when cut, causing serious injury.

Splitting Logs: Preparing Firewood for Burning

Once the logs are bucked, the next step is to split them into smaller pieces for firewood. This is called splitting. Here’s how to do it safely and efficiently:

1. Choose the Right Tool: You can split logs with an axe, a maul, or a log splitter. An axe is best for splitting small logs, while a maul is better for splitting larger logs. A log splitter is the most efficient tool for splitting a lot of firewood. My Take: I use a combination of an axe and a maul, depending on the size of the logs.
2. Use a Splitting Block: Use a splitting block to support the logs while you’re splitting them. This will make it easier to split them and reduce the risk of back strain.
3. Position Yourself Properly: Position yourself properly before splitting a log. Stand with your feet shoulder-width apart and your knees slightly bent.
4. Swing with Your Whole Body: Swing the axe or maul with your whole body, using your legs and core muscles to generate power.
5. Aim for the Center: Aim for the center of the log.
6. Wear Safety Glasses: Wear safety glasses to protect your eyes from flying wood chips.

Data-Backed Insights:

• Using a hydraulic log splitter can reduce the risk of back injuries compared to splitting logs with an axe or maul.
• The optimal size for firewood is between 4 and 6 inches in diameter.

Stacking Firewood: Promoting Optimal Drying

Once the firewood is split, the next step is to stack it properly to promote optimal drying. Here’s how to do it:

1. Choose a Sunny and Windy Location: Choose a location that’s sunny and windy. This will help the firewood dry faster.
2. Elevate the Firewood: Elevate the firewood off the ground using pallets or other materials. This will prevent it from absorbing moisture from the ground.
3. Stack the Firewood Loosely: Stack the firewood loosely to allow air to circulate.
4. Cover the Firewood: Cover the firewood with a tarp or other waterproof material to protect it from rain and snow.
5. Allow Time to Season: Allow the firewood to season for at least 6-12 months before burning it.

Data-Backed Insights:

• Firewood that’s stacked in a sunny and windy location will dry faster than firewood that’s stacked in a shady and sheltered location.
• Covering firewood with a tarp can reduce the moisture content by up to 20%.
