What Kaushal Vikas Chapter 8 Covers

Sheet Metal Work and Plumbing cover cutting, bending, forming and riveting GI or aluminium sheets (defining forming, burr, rivet and gauge), and installing, joining and repairing water pipes and fittings.

Food Processing covers hygienic preparation, preservation, packaging and quality checks for processed food items.

Furniture Making and Pottery explain seasoned wood, joinery, try-square alignment and sanding/varnishing for simple furniture (stools, shelves, boxes), and clay preparation, shaping, drying and firing in pottery.

Key steps and quality: sheet metal work starts with a simple item such as a dustpan, dustbin or chalk box, from sketch to prototype, with gloves, goggles and ear plugs. Plumbing is judged by leak-free joints, straight pipes, secure fittings and smooth flow. Food processing needs clean hands, no cross-contamination and proper storage. Furniture making covers joinery for stools, shelves and boxes. Pottery makes diyas, bowls, cups, tiles and planters.
