Home Built Firewood Processor: 5 Expert Tips for Efficiency

Building your own firewood processor can be a daunting task, but the rewards—increased efficiency, reduced physical strain, and cost savings—are well worth the effort. I’ve spent years tinkering with and refining my own firewood processing setup, and I’m excited to share my experience with you. These five tips are based on my observations, experiments, and lessons learned the hard way.

1. Foundation First: Understanding the Core Components

Before you even think about welding or hydraulics, it’s crucial to understand the core components that make up a firewood processor. This knowledge will guide your design and ensure that your machine is both functional and safe.

• Infeed System: This is where the logs enter the processor. It can be as simple as a ramp or as sophisticated as a powered conveyor.
• Cutting Mechanism: This is usually a chainsaw (gas, electric, or hydraulic) that cuts the log into desired lengths.
• Splitting Mechanism: This is typically a hydraulic splitter that splits the cut rounds into smaller pieces.
• Discharge System: This is how the processed firewood is moved away from the machine, often using a conveyor belt.
• Power Source: This could be a gasoline engine, an electric motor, or a tractor’s PTO (Power Take-Off).
• Control System: This encompasses the levers, buttons, and switches that control the various functions of the processor.
• Safety Features: These are essential for protecting the operator and bystanders. They include guards, emergency stop buttons, and two-hand operation.

Key Concepts Explained:

• Green Wood vs. Seasoned Wood: Green wood is freshly cut and has a high moisture content (often above 50%). Seasoned wood has been dried for several months, reducing its moisture content to 20% or less. Seasoned wood burns more efficiently and produces less smoke.
• Hydraulic Pressure (PSI): Pounds per square inch (PSI) is the unit of measurement for hydraulic pressure. Higher PSI means more force is applied by the hydraulic cylinder.
• GPM (Gallons Per Minute): GPM refers to the flow rate of hydraulic fluid. Higher GPM means faster cylinder operation.

My Experience: I initially underestimated the importance of a robust infeed system. I started with a simple ramp, but quickly realized that it was too slow and required too much manual effort. I upgraded to a powered conveyor, which significantly increased my processing speed.

Actionable Steps:

• Chainsaw Selection: Choose a chainsaw that is powerful enough to handle the diameter of logs you typically process. Consider both gas-powered and electric options. Gas-powered chainsaws offer more power and portability, while electric chainsaws are quieter and require less maintenance.

  • Gas Chainsaws: Look for models with engine sizes between 50cc and 70cc for optimal performance.
  • Electric Chainsaws: Choose models with at least 15 amps of power and a chain speed of 4000 FPM (Feet Per Minute) or higher.

• Chain and Bar Selection: Use a chain with a low-kickback design and a bar length that is appropriate for the size of logs you process. A full chisel chain will cut faster than a semi-chisel chain, but it also requires more frequent sharpening.

• Control System Design: Design a control system that allows you to operate the chainsaw safely and efficiently. Consider using a hydraulic valve to control the chainsaw’s movement and a foot pedal to activate the chain.
• Automatic Oiler: Ensure that your chainsaw has an automatic oiler to keep the chain lubricated. Proper lubrication is essential for preventing chain wear and extending the life of the chainsaw.

Key Concepts Explained:

• Chain Speed: Chain speed is the speed at which the chain moves around the bar, measured in feet per minute (FPM). Higher chain speed results in faster cutting.
• Low-Kickback Chain: A low-kickback chain is designed to reduce the risk of kickback, a dangerous phenomenon that can occur when the tip of the chainsaw bar contacts an object.
• Hydraulic Valve: A hydraulic valve is used to control the flow of hydraulic fluid, which in turn controls the movement of hydraulic cylinders.

My Experience: I initially used a small electric chainsaw, which struggled to cut through larger logs. I upgraded to a gas-powered chainsaw with a larger engine and a full chisel chain, which made a huge difference in my cutting speed. I also added a hydraulic valve to control the chainsaw’s movement, which allowed me to make more precise cuts.

Actionable Steps:

1. Research different chainsaws: Compare the features and specifications of different gas-powered and electric chainsaws.
2. Choose the right chain and bar: Select a chain and bar that are appropriate for the size of logs you process.
3. Design your control system: Create a detailed design of your control system, including the location of the levers, buttons, and foot pedal.
4. Install an automatic oiler: Ensure that your chainsaw has an automatic oiler to keep the chain lubricated.
5. Implement safety features: Install guards and an emergency stop button to protect the operator and bystanders.

3. Splitting Power: Hydraulic System Design and Optimization

The splitting mechanism is responsible for breaking the cut rounds into smaller, more manageable pieces. A well-designed hydraulic system is essential for achieving high splitting power and efficiency.

• Hydraulic Cylinder Selection: Choose a hydraulic cylinder with enough force to split the type of wood you typically process. Consider the diameter and species of wood.

  • Cylinder Size: A 4-inch diameter cylinder with a 24-inch stroke is a good starting point for most firewood processors.
  • Splitting Force: Aim for a splitting force of at least 20 tons.

• Hydraulic Pump Selection: Select a hydraulic pump that can deliver enough flow to operate the cylinder at a reasonable speed.

  • GPM (Gallons Per Minute): A pump that delivers 11-16 GPM is generally sufficient for a firewood processor.
  • PSI (Pounds per Square Inch): Ensure the pump can deliver the required PSI for the cylinder you selected (typically 2500-3000 PSI).

• Hydraulic Valve Selection: Choose a hydraulic valve that is compatible with your pump and cylinder.

  • Spool Valve: A 2-spool valve is a common choice for firewood processors, allowing you to control the cylinder’s movement in both directions.

• Hydraulic Hoses and Fittings: Use high-quality hydraulic hoses and fittings that are rated for the pressure and flow of your system.

• Hydraulic Oil: Use the correct type of hydraulic oil for your pump and cylinder.
• Log Restraints: Install log restraints to prevent the log from moving during the splitting process.

Key Concepts Explained:

• Splitting Wedge: A splitting wedge is a wedge-shaped piece of steel that is attached to the end of the hydraulic cylinder. It is used to split the log.
• Cycle Time: Cycle time is the time it takes for the hydraulic cylinder to complete one full cycle (extend and retract).
• Two-Stage Pump: A two-stage pump delivers high flow at low pressure and low flow at high pressure. This allows for faster cycle times when splitting smaller logs.

My Experience: I initially used a small hydraulic cylinder, which struggled to split larger, knotty logs. I upgraded to a larger cylinder with more splitting force, which made a huge difference. I also added a two-stage pump, which significantly reduced my cycle time.

Actionable Steps:

1. Calculate the required splitting force: Determine the splitting force you need based on the type of wood you typically process.
2. Select a hydraulic cylinder: Choose a cylinder that can deliver the required splitting force.
3. Select a hydraulic pump: Choose a pump that can deliver enough flow to operate the cylinder at a reasonable speed.
4. Select a hydraulic valve: Choose a valve that is compatible with your pump and cylinder.
5. Assemble the hydraulic system: Connect the pump, cylinder, valve, hoses, and fittings.
6. Test the hydraulic system: Test the system to ensure that it is working properly.
7. Install log restraints: Install log restraints to prevent the log from moving during the splitting process.

4. Material Handling: Infeed and Discharge Systems

Efficient material handling is crucial for maximizing the throughput of your firewood processor. A well-designed infeed and discharge system can significantly reduce the amount of manual labor required.

• Infeed System:

  • Log Deck: A log deck is a platform that holds the logs before they are fed into the processor.
  • Log Lift: A log lift is used to lift the logs onto the log deck. This can be a hydraulic lift or a simple ramp.
  • Conveyor Belt: A conveyor belt is used to feed the logs into the cutting mechanism. This can be a powered conveyor or a gravity-fed conveyor.
  • Log Stop: A log stop is used to stop the log at the correct position for cutting.

• Discharge System:

  • Conveyor Belt: A conveyor belt is used to move the processed firewood away from the machine.
  • Firewood Elevator: A firewood elevator is used to lift the processed firewood into a pile or truck.
  • Trommel Screen: A trommel screen is used to separate the firewood from the debris.

Key Concepts Explained:

• Live Deck: A live deck is a log deck with a powered conveyor that automatically feeds logs into the processor.
• Gravity-Fed Conveyor: A gravity-fed conveyor uses gravity to move the logs or firewood.
• Trommel Screen: A trommel screen is a rotating cylindrical screen that is used to separate materials based on size.

My Experience: I initially used a simple ramp to feed logs into my processor, which was slow and tiring. I upgraded to a powered conveyor belt, which significantly increased my processing speed and reduced my fatigue. I also added a firewood elevator to lift the processed firewood into my truck, which saved me a lot of time and effort.

Actionable Steps:

1. Design your infeed system: Consider the size and weight of the logs you typically process.
2. Design your discharge system: Consider how you will store and transport the processed firewood.
3. Choose the right conveyors: Select conveyors that are appropriate for the size and weight of the logs and firewood.
