| Rm.{William Robotham - Chief Engineer}S/ST.11.8.41. - 2 - 6 - BORE WEAR 3½ LITRE ENGINES. This will be brought up again at the next meeting. 7 - BUICK STEM VALVE. This is fitted to 10.B.V. No tests have yet been made. 8 - FLUSH TOP PISTONS. Rm{William Robotham - Chief Engineer}/HH. will make a drawing of the 3¼ bore piston and Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} will order some. 9 - VALVE GEAR WEAR ON 10.G.VII. In view of the fact that this car appears to be functioning quite satisfactorily, it was agreed that inspection should be deferred until 100,000 miles had been run. 10 - REPLACEMENT ENGINE FOR 10.G.VII. This is now on the test bed. Rm.{William Robotham - Chief Engineer} will ask Ry. for a re- port on the cracked crankshaft which came out of this engine. 11 - COMBUSTION CHAMBER DESIGNS. It was agreed that some heads for the 75 mm. should be made with the new cylinder design and tried. Also that the 3¼ bore can now be instructed. 12 - MANUFACTURE OF COMPLETE RANGE OF SIX AND FOUR CYLINDER ENGINES. Rm{William Robotham - Chief Engineer}/HH. stated that he had now completed up to date drawings for the whole range of engines. It was agreed that the Foundry should be asked to produce three castings in every cylinder size. It was agreed that these parts would be instructed direct to the Foundry and that Rm{William Robotham - Chief Engineer}/FTS. would discuss the matter with Walker and Kinegg before the next meeting. 13 - MECHANICAL PETROL PUMP. Rm.{William Robotham - Chief Engineer} pointed out that this had failed on 9.B. when he went to Wolverhampton the other day. As the consumption tests are now finished, he suggested that it should be coupled up; but it should definitely be tested before the car is used for ordinary transport work. 14 - BUICK TYPE PIVOTS. This will be brought up again at the next meeting. | ||
