| To RHC.{R. H. Coverley - Production Engineer} X340 HS{Lord Ernest Hives - Chair}/Std.14/JH.24.3.36. We shall shortly be taking a Phantom III car to Brooklands for radiator cooling tests, and shall require to have the temperature of the circulating water entering and leaving the radiator. Our usual method of measuring the exit temperature i.e. putting a thermometer pocket on the bottom water connection, cannot be used owing to the fact that the bottom water pipe passes through a hole in the crankcase, and therefore it would be necessary to remove the engine in order to fit a thermometer pocket. We should therefore like to put a thermometer pocket on the pump cover as shown on attached sketch the latest type of pump cover being used. This cover is in aluminium and the thermometer pocket could be made by welding sheet aluminium to the cover and the union if this is practicable. If not we suggest that a new pump cover with a suitable pocket be cast in brass and the union sweated into it. As soon as you have completed such a cover we will decide to which car we want it fitted. HS{Lord Ernest Hives - Chair}/Std. | ||
