This section is the core of our lesson. We will explore five important machines, their parts, uses, and then delve into the principles of their care. Part A: Identification, Parts, and Uses of Key Woodwork Machines

(Teacher leads a discussion, using charts, videos, or actual machines) Mortising/Drilling Machine What is it? A machine used to cut square or rectangular holes (mortises) in a piece of wood. Many can also be used as a powerful drill press for making round holes. Key Parts: Motor: Provides the power to rotate the bit. Chuck: Holds the mortising chisel or drill bit securely. Table: A flat surface where the workpiece is placed and clamped. Fence: An adjustable guide to position the workpiece accurately. Feed Lever/Handle: Used by the operator to lower the cutting tool into the wood. Uses: Primarily for creating mortise and tenon joints, which are fundamental in making furniture (chairs, tables) and door frames. Also used for precision drilling. Router Shaping Machine (Router/Shaper) What is it? A versatile machine used for hollowing out an area in a piece of wood, creating decorative edges, and shaping profiles. A handheld version is a router; a larger, stationary version is a shaper. Key Parts: Motor: A high-speed motor that spins the cutting bit. Collet: A specialised chuck that grips the router bit. Base: The flat platform that rests on the wood surface, providing stability. Depth Adjustment: A mechanism to control how deep the bit cuts into the wood. (For Shapers): Spindle: A vertical shaft that holds the cutting tool. Uses: Creating decorative mouldings, cutting grooves (dadoes, rabbets), trimming edges, and carving intricate designs. Essential for kitchen cabinets, wardrobes, and decorative furniture. Grinding Machine (Bench Grinder) What is it? A machine with abrasive wheels that spin at high speed, used for grinding, sharpening, and shaping metal tools. It is crucial in a wood workshop for maintaining hand tools. Key Parts: Motor: Drives the grinding wheels. Grinding Wheels: Two abrasive wheels, often one coarse and one fine. Tool Rest: An adjustable support to hold the tool being sharpened at the correct angle. Safety Guards/Eye Shields: Clear shields to protect the operator from sparks and debris. Uses: Sharpening chisels, plane irons, drill bits, and other cutting tools. A sharp tool produces better work and is safer to use. Lathe Machine What is it? A machine that rotates a workpiece on its axis, allowing it to be shaped by cutting tools. It's for creating cylindrical or "turned" objects. Key Parts: Headstock: Contains the motor and drive system; it holds and rotates one end of the workpiece. Tailstock: A movable support for the other end of the workpiece. Bed: The main horizontal beam that connects the headstock and tailstock. Tool Rest: An adjustable support for resting the turning tools (chisels, gouges) on during cutting. Uses: Making round table legs, chair legs, lampstands, bowls, and other rounded or symmetrical wooden items. It is a cornerstone of artistic and traditional woodwork. Drum Sander Machine What is it? A machine that uses a rotating cylindrical drum covered with sandpaper to smoothen the surface of wood, especially wide boards. Key Parts: Sanding Drum: The main rotating cylinder wrapped in abrasive paper. Conveyor Belt/Table: Moves the wood under the sanding drum at a consistent speed. Dust Collection Port: An outlet to connect a vacuum system to remove sawdust. Height Adjustment Crank: Used to set the distance between the table and the drum, controlling the amount of wood removed. Uses: Achieving a perfectly flat and smooth finish on large surfaces like tabletops, cabinet doors, and floorboards before applying varnish or paint. Part B: Principles of Machine Care and Maintenance

(Teacher explains these principles using a whiteboard and demonstrating with tools like an oil can and rag)
