Electric saw Jig saws are invaluable for general cutti of timber and sheet materials. The best saw will have a reciprocal blade and blowing action to clear the cutting line. 1 Power drill 2 Masomy bit 3 Twist bits 4 Radiator cleaning bit 5 Cordless drilllscreiodn 6 Screwdriver bits and extension 7 Countersink attachme 8 Polishing pad 9 Sanding sheets 10 Rotary sanding/polis! attachment Scroll action is another refinement, enabling you to make tight curved cuts by turning the blade and not the whole tool. Circular saws are useful for cutting sheet materials and timber in a straight line. These are not as versatile as jig saws – and they are considerably less safe to use. Different blades are available for cutting a variety of materials. Electric sander Rotary sanders are attachments for power drills. Glasspaper is fitted to a simple sanding disc or, for a better finish, a foam drum sander. A foam drum sander gives a good finish on both flat and shaped surfaces. An orbital sander is a dedicated power tool, which drives a rectangular pad fto which the sandpaper is fixed) in small, rapid orbits. Use gentle pressure falways with both hands on the tool) to produce a smooth finish in quick time.

available in size for orbital sanders. When you have completed sanding a floor with an industrial appliance, an orbital sander will give a smooth finish and is particularly useful for edges and corners of floors. Most sanders will work on wood, plastics, metals, or fillers, so long as the abrasive is suited to the top. A random orbital sander uses circular, grip-on pads and works in eccentric movements. Hot air stripper This is a convenient alternative to a blowlamp for softening and stripping the old paint, particularly oil-based paint from the woodwork. You can use a blowlamp which works off bottled gas, or a hot-air gun which is powered by electricity.
