Pro Tips for Firewood Prep with the Dolmar 510

Now that we’ve covered the basics of the Dolmar 510, let’s dive into some pro tips for using it to prepare firewood efficiently and safely.

Efficient Bucking Techniques

• Use a sawbuck: A sawbuck is a simple wooden frame that holds logs in place while you buck them. This allows you to cut multiple logs at once, saving time and effort.
• Cut multiple logs at once: If you have several logs of the same diameter, you can stack them together and cut them all at once. This is much faster than cutting each log individually.
• Use the “step-over” method: When bucking large logs, use the “step-over” method. This involves cutting partway through the log from one side, then stepping over the log and finishing the cut from the other side. This helps to prevent the log from pinching the chain.
• Maintain a sharp chain: A sharp chain will cut through wood much faster and more efficiently than a dull chain.

Splitting Techniques

• Use a log splitter: A log splitter is a hydraulic machine that splits logs with ease. This is the most efficient way to split large quantities of firewood.
• Use a splitting maul: A splitting maul is a heavy axe-like tool that is used to split logs by hand. This is a good option for smaller quantities of firewood or for splitting logs that are too large for a log splitter.
• Use wedges: Wedges are metal or wooden tools that are driven into the log with a sledgehammer. This is a good option for splitting particularly tough or knotty logs.
• Split with the grain: Always split logs with the grain of the wood. This will make the splitting process much easier.

Wood Drying and Storage

• Season your firewood: Seasoning firewood involves allowing it to dry for several months before burning it. This reduces the moisture content of the wood, making it burn hotter and cleaner.
• Stack your firewood properly: Stack your firewood in a way that allows for good air circulation. This will help it to dry more quickly.
• Store your firewood in a dry place: Store your firewood in a dry place, such as a shed or under a tarp. This will protect it from rain and snow, which can slow down the drying process.
• Monitor moisture content: Use a moisture meter to monitor the moisture content of your firewood. The ideal moisture content for burning firewood is below 20%.

Metrics for Success:

• Processing Time: Track the time it takes you to process a cord of firewood from start to finish. This will help you to identify areas where you can improve your efficiency.
• Moisture Content: Regularly check the moisture content of your firewood to ensure that it’s properly seasoned.
• Equipment Maintenance: Keep track of your chainsaw’s maintenance schedule to ensure that it’s running smoothly and efficiently.

Personal Tip: I’ve found that using a combination of techniques is the most effective way to prepare firewood. I use the Dolmar 510 to fell trees and buck logs, a log splitter to split most of the wood, and a splitting maul for the tough stuff. I also make sure to season my firewood properly and store it in a dry place.
