Jacks Rm{William Robotham - Chief Engineer} reports that this matter is progressing and that someone is proceeding to the Works of Lockheed and Smith to investigate the progress. Valve Gear Clatter E.{Mr Elliott - Chief Engineer} reported that the materials used for the rocker cover, i.e. magnesium, are resonant, and it is recommended that they revert to aluminium. Engine Bearings A discussion took place on this in view of the fact that the bearings on Hancock's car did not stand up. It was decided to revert to the marine type connecting rod, and by the use of white metal bearings the difficulties experienced in production would be minimised. Mx{John H Maddocks - Chief Proving Officer} was instructed forthwith to proceed with his piston tests by the adoption of the short liners necessary for this arrangement. [Handwritten note: Don't agree] Autolock This matter was discussed, and it was agreed that the first 50 cars must have this device. Our first impressions that the trouble has been reduced, when passing over humpback bridges, are due only to alterations in the front springing and making the riding a bit harsher. Alignment of Engine and Gearbox The merits of the unit construction as opposed to the separate engine and gearbox were discussed. It was decided to produce two types of gears at first, the coarser gears enabling the box to be more rigidly mounted in the frame, and this is a help in the maintenance of alignment. Hydraulic Tappets. The criticisms of hair and fluff from the filter, referred to by Hancock, were discussed, and it was decided to | ||
