LOOSE BOLTS

TIGHT NUTS. Many holts upon the chassis and body of a motor car are so placed that the head is iriaccessible, ahd only the nut for manipulation available. It often happens that with use these bolts become lqose, and at the same time th'e hut by rUst or for some other reason seizes on to the thread, and efforts either to remove or tighten it fail because the whole bolt turns as the wrench is applied to the nut. There are two ways in which a nut ■ may be turned in "such circumstances. If the portion of the bolt protruding from the nnt is long enough, two other nuts may be screwed on to it and locked together. They can then be held in a wrench while the rustedup nut is eased with another wrench. Once this nut begins to turn its .com- ; plete removai is usually not difficult if the thread be carefully cleaned and oiled. An altefnative method '6f h'Olding a bolt while a hut is eased is to 'cut a slot across the end of the bolt with a hacksaw. A screwdriver can then be applied to this slot to prevent the bolt from turning. Practically all modern cars are now equipped with. head lamps having twin-filament hulbs. This enables the beam of light to he dipped at the touch of a switch, so that a useful driving light is retained, 1 although dazzle is totally eliminated. _ This Valuable refinement may easily be fitted to any car having the usual single-wire system of cahles. Necessary parts are neat ahd simple, consisting of a pair of douhle-contact lamp sockets of a type suitable for replacing the single-contact ones in the lamps; double-filament bulbs, . a two-way tumbler switch, ohtainable from a dealer in house-lighting fit- • tings, and douhle the ainount of flex necessary to run from the dash to the froht of the 'car.
