| HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Std. 340 Rm{William Robotham - Chief Engineer}/Std.17/AP.16.4.37 As discussed with you, we wish to carry out corrosion tests on two Ph.III. crankcases cyl. heads etc. with the minimum of delay. We are arranging with W.Bell. to construct a rig consisting of the necessary portions of a Ph.III. engine unit connected to a Ph.III. radiator. The water pump will be driven by an electric motor and the water heated by electricity or gas. Will you please prepare for us as soon as possible one Ph.III. crankcase as standard (it can be an old or scrap case) and one new Ph.III. crankcase which should be anodically oxidised throughout the water space and then treated with the standard linseed oil doping. The first case should be built up with a pair of cylinder heads, water rails, hot spot box, water pump and drive as standard - after we have tested this case we shall require the second case building up in a similar manner but using an aluminium hot spot box and a pair of cylinder heads which have also been anodically oxidised internally ( we believe that this could be carried out on already machined heads or boxes.) It is necessary that we should find a cure for this corrosion with a minimum of delay since we have already experienced trouble on Production. Rm{William Robotham - Chief Engineer}/Std. | ||
