What type of guards should jointers be fitted with

Jointing machines are important woodworking machines used to create a flat surface on wood, ensuring the edges are straight and true for further processing. While they are a valuable tool in any woodworking shop, safety must always be the top priority when handling connectors. One of the most critical aspects of ensuring safety is the proper use of guards. This article will explore the types of guards that should be installed on joints, their importance, and best practices for safe operation.

Understand connectors

Before delving into the details of guards, it is necessary to understand what connectors are and what they do. The combined machine consists of a platform, a cutterhead and a fence. The cutter head contains a sharp blade that rotates at high speed to remove material from the wood to create a flat surface. Jointers are often used to prepare wood for further processing, such as planing or joining edges for gluing.

While connectors are powerful tools that can produce precise results, they also come with significant risks. High-speed blades can cause serious injury if proper safety measures are not taken. This is where guards come into play.

The Importance of Guarding

Guards are safety devices designed to protect the operator from the moving parts of the machine. They have several key functions:

  1. Prevent Contact with Blade: The main purpose of the guard is to prevent accidental contact with the blade. This is crucial because even a brief lapse in concentration can lead to serious injury.
  2. REDUCED Lumber Kickback: When using joiners, there is a risk of wood kickback, where the wood may be pushed back towards the operator. Proper guards can help minimize this risk by controlling the movement of wood.
  3. Enhanced Visibility: Guards also enhance workpiece visibility, allowing operators to monitor the cutting process without compromising safety.
  4. Comply with regulations: Many areas have safety regulations that require specific guards to be installed on woodworking machinery. Complying with these regulations is not only a legal obligation but also a best practice to ensure safety.

Connector Guard Type

For connectors, several types of guards can be installed for added safety. Each type serves a specific purpose and can be combined to provide comprehensive protection.

1. Blade Guard

The blade guard is designed to cover the rotating blades of the splicing machine. These guards are usually adjustable and can be positioned to allow for different thicknesses of wood while still providing protection. They should be designed to automatically return to their original position after the passage of wood, ensuring that the blades are always covered when not in use.

2. Feeding and discharging protection device

Infeed and outfeed guards are located at the entry and exit points of the joining machine. These guards help guide the wood into the cutter head while preventing the operator’s hands from getting too close to the blade. They should be adjustable to accommodate different sizes of wood and should be designed to minimize the risk of kickback.

3. Anti-kickback device

Anti-kickback devices are essential to prevent wood from being pushed back toward the operator. These devices can take many forms, such as pawls or rollers, which grip the wood and prevent it from moving backwards. They should be positioned close to the cutter head and designed to allow forward movement of the wood while preventing backward movement.

4. Putter and Push Block

Although push rods and push blocks are not traditional guards, they are important safety tools that should be used when operating a splicing machine. These devices allow the operator to push lumber through the jointer without having to put hands near the blades. They should be used when the wood is too short to handle safely by hand.

5. Emergency stop switch

While an emergency stop switch is not a guard in the traditional sense, it is an important safety feature and should be easy to operate. These switches allow operators to quickly close the connector in an emergency, preventing potential injury.

Best practices for using guards on connectors

While it is crucial to install proper guarding, it is equally important to follow best practices for its use. Here are some tips for ensuring safety when handling joints:

  1. Regular Maintenance: Make sure all guards are in good working order and properly adjusted. Check the protective cover regularly for wear and replace if necessary.
  2. Training: Ensure all operators receive training on the importance of proper use of connectors and guards. They should know how to adjust the guard for different thicknesses of wood and how to use the push rod effectively.
  3. Keep the Area Clean: A clean workspace reduces the risk of accidents. Make sure the area around the adapter is clear of debris and that the machine itself is clean and well-maintained.
  4. Use Proper Technique: Always use the adapter according to the manufacturer’s instructions. Avoid forcing wood through the machine and always feed it in the correct direction.
  5. STAY FOCUS: Distractions can lead to accidents. Always stay focused when operating the jointer and avoid engaging in conversations or multitasking while using the machine.
  6. Wear appropriate personal protective equipment (PPE): In addition to protective gear, operators should also wear appropriate PPE such as safety glasses, hearing protection, and dust masks to protect against flying debris and noise.

in conclusion

Connectors are powerful tools that can significantly enhance a woodworking project, but they also come with inherent risks. Installing appropriate guards is vital to ensure the safety of the operator and anyone nearby. By understanding the types of guards available and following best practices for their use, woodworkers can minimize the risk of accidents and injuries. Remember, safety should always be the top priority in any woodworking environment.
