| Dealing with the progress made in each particular section of the chassis. RADIATOR & COOLING. Latest 18 x 62 core 10-15% more efficient. We can and must get Marstons to produce this core as soon as possible. We have a Chevrolet and Buick radiator on the way showing the more or less standardised method of construction. Very light and cheap to produce. Any points not already incorporated on Wraith radiator should receive attention. A better oil cooler has been developed and we are handing RHC.{R. H. Coverley - Production Engineer} a model to see if he can manufacture it. COACHWORK, HEATING & COOLING. Air conditioning is rather too advanced and complicated to justify our giving it attention, particularly in such a temperate climate as England. The small defrosters consisting of warm air blown from the car heater on to the wind screen are excellent. We have samples and can get Claytons to manufacture, but one difficulty will be to get provision made by the coachbuilder for the hot air to get to the windscreen. Ev.{Ivan Evernden - coachwork} should provide a sketch of what is required so that if and when demanded by the customer it can be built into the car. FRONT SUSPENSION. From the point of view of silence, freedom from lubrication joints, etc. we prefer the Packard. We believe that eventually rubber will be universally used for front suspension joints. The difficulty in England will be getting the correct grade of rubber. The Dubonnet will work well on a small car, but is considerably heavier than the wishbone scheme, particularly when applied to a big car. It is more expensive to produce than a wishbone layout. The Cadillac and Buick layout of wish-bones is giving satisfaction, though threaded shackles suffer from exposure. We have not tried a softly sprung car of the conventional type that compares with the independently sprung cars for directional stability. SHOCK ABSORBERS. The new bicycle pump shock absorbers are excellent in conception, being lighter and less costly than the type we are using. Samples obtained. We must find some way of getting these made in England, and in the meantime, proceed with experimental test. | ||
