| -2- (a) We have breathing vents. (b) Anti surge tank. (c) Anti surge trough for gauge. (d) Tank baffles, (e) Our fittings are heavier. It was agreed that we should design the petrol tank for Ripplet using the wrapped design and the gauge (22+thous.) lead sheet with stiched ends. The tank should have no baffles and the finger grooves atop the top of the tank, the filler is to be on the top of the tank and all fittings are to be lightened. A similar tank is to be designed although of smaller capacity for the Rippletto, with Rm{William Robotham - Chief Engineer}'s. instructions for tank rationalisation. (5) Gearbox. The gearbox is to have no drain plug, The washer of the cover is to be stuck to the casing to hold in position the selector balls and springs so that this cover may be used for draining the gearbox. (6) Hand Brake. A simplified design of hand brake lever is to be produced for the senior range. (7) Simplified Flexible Flywheel. Rm.{William Robotham - Chief Engineer} promised to get details of the design of such a flywheel which is already in existance from NRC.{N. R. Chandler} (8) Rear Axles. Rm.{William Robotham - Chief Engineer} stated that he wished the alum axle as projected by Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} to be designed for application to the Senior Range. | ||
