THAT SCREEN WIPER.

MAKE IT PERMANENT. The automatic windscreen wiper is a reasonably reliable piece ol' medianism, but its transmission system, usually a piece of perishable rubber tubing is a fruitful source of failure. Indeed, *the bappy-go J .U)Cky type of motorist rarely has bis wiper woritinging except when he works it by hand, while even the most methodical are apt to leave it inoperative for days on end in postponing the search for that elusive leak.

The iirst step in attaining absolute reliability in tiie windscreen wiper is to scrap the rubber tubing. In its place buy a length of largesized waterproof Bowden cable casing, as generally used for motor-cycle clutch controls, also about six inches of rubber gas tubing sutticiently large to fit over the (able. The rubber tubing is jor connecting up at the induction pipe and wiper ends, and if it proves too big to tit the small pipes at these extremities, a turn or so of insulation tape round them will cure this. Having made the connections by the use of the rubber tubing, wrap it well with insulation tape, entirely binding the rubber, then give the tape a final coating of shellac or paint or enamel to lender the binding permanent. Thereafter you should have no more trouble as regards visibility till the actual mechanism wears out. The trouble with the ordinary rubber tubing is that heat destroys it at the engine end, and sharp bends and sun at the windscreen end. By binding it with tape at the joints and at the bends it can be rendered reasonably durable, provided it does not come in close proximity with the exhaust pipe at the induction end.
