With this in mind, let’s dive into the three pro arborist tips that will transform your cutting game.

Tip #1: The Undercut, Overcut, and Meeting Cut – The Foundation of Control

This is the bread and butter of professional tree felling and limb removal. It’s all about managing the forces within the wood to prevent pinching and splintering.

Wood Anatomy and the Importance of Managing Tension

Wood isn’t just a solid, uniform substance. It’s a complex matrix of cells, fibers, and vessels, all arranged in a specific pattern. Understanding this anatomy is crucial for predicting how wood will behave under stress.

Tension and Compression: When a tree branch is hanging, the upper side is under tension (being pulled apart), while the lower side is under compression (being squeezed together).
Fiber Direction: Wood fibers run lengthwise, making wood strong along the grain but weaker across it.
Moisture Content: The moisture content of wood significantly affects its strength and flexibility. Green wood is more pliable, while dry wood is more brittle.

I once worked on a project involving the removal of a large, leaning pine tree. The tension on the upper side of the trunk was immense. Without proper cutting techniques, the trunk could have split violently, posing a serious safety hazard. That’s where the undercut, overcut, and meeting cut came into play.

The Undercut: Relieving Tension and Preventing Splintering

The undercut is the first step in this cutting sequence. It involves making a notch on the underside of the branch or trunk, typically about one-third of the diameter.

Purpose: The undercut relieves the tension on the lower side of the wood, preventing it from splintering upwards as the cut progresses.
Technique: Use the tip of your chainsaw bar to create a clean, angled cut upwards. Ensure the angle is steep enough to create a clear notch.

The Overcut: Controlling the Fall and Preventing Pinching

The overcut is the second step, made on the upper side of the branch or trunk, slightly above the undercut.

Purpose: The overcut controls the direction of the fall and prevents the chainsaw bar from getting pinched as the wood closes in.
Technique: Start the overcut a few inches above the undercut and cut downwards, aiming to meet the undercut.

The Meeting Cut: Completing the Cut with Precision

The meeting cut is the final step, where you carefully connect the undercut and overcut.

Purpose: To cleanly sever the wood without causing splintering or kickback.
Technique: Once the overcut gets close to the undercut, slow down and use precise movements to connect the two cuts. Avoid forcing the chainsaw.

Data-Backed Benefits of the Undercut, Overcut, Meeting Cut

Reduced Splintering: Studies have shown that using this technique reduces splintering by up to 80%.
Improved Safety: This technique significantly reduces the risk of chainsaw kickback and uncontrolled falls.
Enhanced Wood Utilization: Clean cuts minimize waste and maximize the usable timber.

Real-World Example: Removing a Large Oak Limb

Let’s say you need to remove a large oak limb that’s overhanging a house.

Assess the Situation: Carefully examine the limb, noting its size, weight, and the direction of lean.
Make the Undercut: Use your chainsaw to create a clean undercut on the underside of the limb, about one-third of the diameter.
Make the Overcut: Start the overcut a few inches above the undercut and cut downwards, aiming to meet the undercut.
Complete the Meeting Cut: Carefully connect the overcut and undercut, allowing the limb to fall safely and cleanly.

Actionable Advice: Practice Makes Perfect

Start with Smaller Branches: Practice this technique on smaller branches before tackling larger, more challenging cuts.
Use a Sharp Chain: A sharp chainsaw chain is essential for making clean cuts.
Maintain a Stable Stance: Ensure you have a firm, balanced stance before making any cuts.

Tip #2: Mastering Bore Cutting – A Precision Tool for Complex Situations

Bore cutting is an advanced technique that allows you to make cuts from within the wood, providing greater control and precision in complex situations.

Understanding the Mechanics of Bore Cutting

Bore cutting involves plunging the tip of the chainsaw bar into the wood and then using the bar to create a cut from the inside out. This technique is particularly useful when you need to remove a section of wood without affecting the surrounding areas.

I remember using bore cutting techniques on a project where we had to remove a section of a tree trunk that had been damaged by insects. The surrounding wood was healthy, and we wanted to avoid causing any further damage. By using bore cutting, we were able to remove the damaged section with pinpoint accuracy.

When to Use Bore Cutting

Removing Internal Decay: Bore cutting allows you to access and remove internal decay without damaging the surrounding wood.
Creating Hinges: This technique is essential for creating hinges when felling trees, allowing you to control the direction of the fall.
Releasing Trapped Chainsaws: If your chainsaw gets pinched in a cut, bore cutting can be used to create space and release the bar.

The Bore Cut Technique: A Step-by-Step Guide

Assess the Situation: Carefully examine the wood and determine the best entry point for your bore cut.
Establish a Pivot Point: Use the tip of your chainsaw bar to establish a pivot point on the wood.
Plunge the Bar: Carefully plunge the tip of the chainsaw bar into the wood, using a slow, controlled motion.
Create the Cut: Once the bar is fully inserted, use it to create the desired cut, moving the bar from side to side.
Withdraw the Bar: Slowly and carefully withdraw the chainsaw bar from the wood.

Safety Considerations for Bore Cutting

Bore cutting can be a dangerous technique if not performed correctly. Here are some important safety considerations:

Use a Sharp Chain: A sharp chainsaw chain is essential for safe and efficient bore cutting.
Maintain a Firm Grip: Keep a firm grip on the chainsaw and maintain a stable stance.
Be Aware of Kickback: Bore cutting can increase the risk of chainsaw kickback. Be prepared for this possibility and take precautions to avoid it.
Avoid Overheating: Bore cutting can cause the chainsaw bar to overheat. Take breaks to allow the bar to cool down.

Bore Cutting for Hinge Creation: A Case Study

Creating a hinge is a critical step in tree felling. The hinge controls the direction of the fall and prevents the tree from twisting or kicking back. Here’s how to use bore cutting to create a hinge:

Make the Face Cut: Create a face cut on the side of the tree in the direction you want it to fall.
Bore Cut to the Hinge: Use bore cutting to create a cut that extends from the back of the tree to the hinge.
Leave the Hinge Intact: Leave a section of wood intact to form the hinge. The size of the hinge will depend on the size of the tree and the desired direction of fall.
Make the Felling Cut: Make the felling cut from the back of the tree, leaving the hinge intact.
Use Wedges (If Necessary): If the tree doesn’t start to fall on its own, use wedges to encourage it to fall in the desired direction.

Practical Tips for Bore Cutting Success

Practice on Scrap Wood: Practice bore cutting on scrap wood before attempting it on a real tree.
Use a Chainsaw with a Narrow Bar: A chainsaw with a narrow bar is easier to control when bore cutting.
Keep the Chain Oiled: Proper lubrication is essential for smooth and efficient bore cutting.

Tip #3: The Importance of Chainsaw Maintenance – Keeping Your Tool Sharp and Ready

This might seem obvious, but it’s the most overlooked aspect of achieving clean cuts. A dull chainsaw is not only inefficient but also dangerous.
