Lesson Content/Board Summary

Router and Spindle Moulder, Parts and Uses

The Router Machine

A router is a power tool used for hollowing out an area in a relatively hard material like wood or plastic. It is primarily used for routing edges, cutting grooves, and creating decorative profiles.

Parts of a Router Machine

Key parts of a router machine include:

1. Motor Housing: Encases the electric motor that drives the spindle.
2. Collet: A clamping device that holds the router bit securely.
3. Base Plate: The flat bottom part that rests on the workpiece and guides the router.
4. Depth Adjustment Mechanism: Allows precise setting of the cutting depth for the bit.
5. Handles: Provide grip and control for the operator during use.
6. Power Switch: Turns the motor on or off.
7. Router Bit: The cutting tool inserted into the collet, available in various shapes and sizes.

Uses of a Router Machine

A router machine is used for various woodworking tasks, such as:

1. Edge Profiling: Creating decorative edges on tabletops, shelves, and panels.
2. Cutting Grooves and Dadoes: Making channels for joints or decorative purposes.
3. Rabbeting: Cutting a step-shaped recess along the edge of a workpiece.
4. Template Routing: Following a template to create identical shapes or patterns.
5. Inlay Work: Cutting recesses for decorative inlays.
6. Trimming Laminates: Neatly trimming excess laminate from edges.

The Spindle Moulder Machine

A spindle moulder (also known as a shaper) is a stationary woodworking machine used for shaping wood by rotating a cutting tool (cutter block) at high speed. It is ideal for producing complex profiles, tenons, and rebates on larger workpieces.

Parts of a Spindle Moulder Machine

Key parts of a spindle moulder machine include:

1. Spindle: The vertical shaft that holds and rotates the cutter block.
2. Table: The flat work surface where the workpiece is supported and guided.
3. Fence: Adjustable guides that control the depth of cut and guide the workpiece past the cutters.
4. Guard: A safety device that covers the rotating cutter block to prevent accidental contact.
5. Hold-downs/Hold-ins: Devices used to keep the workpiece firmly against the table and fence during machining.
6. Cutter Block/Cutters: The cutting tools, which are usually interchangeable and come in various profiles.
7. Rise and Fall Mechanism: Adjusts the height of the spindle and cutter block.
8. Power Feed Unit (Optional): Automatically feeds the workpiece past the cutters for consistent results and increased safety.

Uses of a Spindle Moulder Machine

A spindle moulder machine is used for a wide range of heavy-duty shaping operations, including:

1. Shaping and Moulding: Creating intricate profiles on edges, such as crown mouldings, door frames, and window sashes.
2. Tenoning: Cutting tenons for mortise and tenon joints, especially for larger components.
3. Grooving and Rebating: Producing precise grooves and rebates for panel inserts or joinery.
4. Panel Raising: Creating decorative raised panels for cabinet doors.
5. Profiling: Machining custom profiles for furniture components and architectural details.

For further understanding, students can search for videos on YouTube using the terms:

• “Router machine parts and uses”
• “Spindle moulder machine operation”
• “Woodworking router techniques”

Teacher Guide for Using This Lesson Plan

Before the lesson, ensure you have clear and accurate diagrams or charts of both a router machine and a spindle moulder machine. If possible, bring actual router bits and spindle moulder cutters to show the students. Begin by engaging students with questions about their prior knowledge of woodworking machines. Systematically introduce each machine, its parts, and then its uses, allowing time for questions and discussion. Emphasise the practical application of each machine. During the instructional procedures, guide students through identifying parts on the diagrams and describing their functions. Encourage active participation throughout. Ensure students copy the Board Summary notes accurately after the main teaching points have been covered. Conclude by reinforcing the importance of safety in machine woodworking.
