how to cut a log lengthwise with a chainsaw


Cutting a log lengthwise with a chainsaw can be a useful technique for various woodworking or construction projects. However, it’s essential to follow safety precautions and use proper techniques to prevent accidents. Here’s how to cut a log lengthwise with a chainsaw:

Materials You’ll Need:

  • Chainsaw with a sharp chain
  • Log or timber
  • Sawhorses or a stable work surface
  • Personal protective equipment (PPE), including safety goggles, ear protection, gloves, and appropriate clothing
  • Chainsaw chaps or pants (optional but recommended for added safety)

Safety Precautions:

  1. Ensure you have the necessary safety equipment and wear it at all times while operating the chainsaw.
  2. Choose a well-ventilated outdoor area for cutting, away from people, structures, and combustible materials.
  3. Ensure the log is secure and stable on sawhorses or a work surface.
  4. Keep bystanders and pets at a safe distance.
  5. Familiarize yourself with the chainsaw’s controls and safety features.

Steps to Cut a Log Lengthwise with a Chainsaw:

  1. Position the Log:
    • Place the log on sawhorses or a stable work surface with the side you want to cut facing up.
  2. Measure and Mark:
    • Determine the lengthwise cut you want to make on the log and measure and mark it using a chalk line or a straightedge. Ensure your markings are straight and accurate.
  3. Starting the Chainsaw:
    • Start the chainsaw according to the manufacturer’s instructions. Ensure the chain is sharp, and the saw is properly maintained.
  4. Cutting the Log:
    • Stand on one side of the log, ensuring you have a stable and balanced stance.
    • Hold the chainsaw firmly with both hands, placing one hand on the rear handle and the other on the front handle.
    • Position the chainsaw with the bar and chain along the marked cutting line.
    • Engage the chainsaw throttle and begin cutting slowly and steadily.
    • Keep the chainsaw steady, maintaining a controlled motion along the marked line. Do not force the chainsaw through the log; let the chain do the work.
    • Pay close attention to the chain’s progress and the depth of the cut. Ensure the chain remains in contact with the log at all times.
    • Use caution when approaching the end of the log to prevent the chainsaw from striking the ground or surface below.
    • If the log is particularly large or challenging to cut, you may need to make a series of passes along the same cut line to achieve the desired depth.
  5. Completing the Cut:
    • Once you’ve cut through the log, release the throttle to stop the chainsaw.
    • Allow the chain to stop moving completely before setting the chainsaw down.
    • Carefully inspect the cut and make any necessary adjustments or additional passes to achieve a clean and straight cut.
  6. Safety First:
    • Always prioritize safety when operating a chainsaw. When finished, turn off the chainsaw, engage the chain brake, and set it aside in a safe location.
    • Dispose of any wood scraps safely and store the chainsaw properly.

Remember that chainsaws are powerful tools that can be dangerous if not used correctly. If you’re not experienced with chainsaw use, consider seeking guidance from a knowledgeable person or a professional, and always prioritize safety.
