1. Identification of Cutting Tools
Cutting tools are tools designed to remove material by cutting through it. Common cutting tools used in woodwork include:
- Crosscut Saw: Used for cutting across the grain of wood.
- Rip Saw: Used for cutting along the grain of wood.
- Tenon Saw: Used for making precise cuts in wood, especially joints.
- Chisel: Used for carving, shaping, and cutting wood.
- Plane: Used for smoothing and shaping wood surfaces.
- Coping Saw: Used for cutting curves and intricate shapes in wood.
Examples:
- A crosscut saw is ideal for cutting boards into smaller pieces.
- A chisel can create mortises for joints.
2. Uses of Cutting Tools
Each cutting tool has a specific purpose in woodworking:
- Crosscut Saw: Cuts wood perpendicular to the grain for shorter pieces.
- Rip Saw: Cuts wood parallel to the grain for longer pieces.
- Chisel: Shapes wood and creates detailed designs.
- Plane: Smoothens rough edges for a polished finish.
- Coping Saw: Makes decorative cuts or curves.
Examples of Usage:
- A tenon saw is commonly used when creating a mortise and tenon joint.
- A plane is used to achieve a smooth tabletop finish.
3. Proper Techniques for Using Cutting Tools
Using cutting tools correctly ensures safety and precision.
General Rules:
- Select the right tool for the task.
- Secure the wood firmly before cutting.
- Hold the tool at the proper angle for the best results.
- Apply consistent pressure without forcing the tool.
- Maintain a steady pace to avoid splintering the wood.
Examples:
- When using a crosscut saw, align the saw teeth with the cutting line.
- While carving with a chisel, always push the tool away from your body to avoid injury.
