6. It is then pulled through the hole in the box.

6. The cable channel is covered. This is done by filling it with plaster, which is then painted or papered.

6. The socket is connected to the cable by inserting each wire in the terminal and tightening the screw (see FIG. 3).

6. The socket is screwed to the box.

Making a car panel

This panel (FIG. 1) fits

onto- the front right-hand

side of a car. It is made

by three methods. \

First, sheet steel is made. This is done by pushing a piece of steel between two rollers (see FIG. 2), which squeeze the metal and make it longer and thinner. This method is called ROLLING. Not all metals can be rolled. For example, iron cannot be rolled because it is too brittle. But steel can be rolled because it is tough and malleable enough.

Next, the steel is cut into a flat shape (see FIG. 3). This is done by placing the i sheet onto a die, and then cutting a hole in it with a punch. The method is called \ PUNCHING. The steel can be cut easily because it is now very thin.

Finally, the sheet steel is bent and pressed into a rounded shape (like in FIG. 1). This is done by putting the sheet onto a die and then bending the sheet around the die with a press (see FIG. 4). This method is called PRESSING. It is not ] difficult to press sheet steel because it is thin and malleable. ,

_{PAINTING EQUIPMENT}

First, you need paint brushes. There are three main types: broad, narrow and angled. Use the broad brush for broad flat areas such as walls. Use the narrow one for corners. And use the angled one for window frames and difficult angles.

Next you need a roller for painting flat surfaces smoothly. Use a long extension on the handle for reaching high places, such as ceilings.You will also need a tray for holding the paint and the roller.

Next, you need a paint pot for holding the paint and the brush. Make sure that the mouth of the pot is wide enough for the widest brush, and that it is small enough to carry.

Next, you need a stepladder for climbing up to the job, a scraper for scraping off old paint and paper from the walls, cloths for covering the furniture, and rags for cleaning paint off the floor.

Finally, you need turpentine for cleaning the paint brushes and rollers.
