| -2- TURNING CIRCLE. x426 This appears to be slightly on the increase. From my old notes I find that we used to turn the old 40/50 (about 1100 series) long chassis in approximately 44 ft. and the short chassis in about 42 ft. From trials taken recently the average circle is about 48 ft. All these figures refer to the diameter of the space required to turn the car round, taken to the outside of the outside wheels (standard 895 m/m). JACKING UP CARS. Mr Hanbury has suggested to me how much better it would be to have the same height from ground to each axle. At present there is a difference of about 2¼". If the under side of back axle had a bracket fitted to make the height same as front axle the great jack question would be simplified. SELF STARTERS. I have sent to W particulars of The Ever-Ready Automatic Engine starter. This is working quite well on a four cylinder Austin car which I have seen. NAVALTUM. I have sent to W some particulars of this metal, which appears to be an improved aluminium alloy. I should like to know whether the Works consider this metal is likely to prove of use for lamp brackets, wing stays, and other parts. [FR Monogram] | ||
