| To BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} X7410 Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}2/LG14.11.27. 14-EX - COACHBUILDERS DRAWINGS. X7830 We asked for .250 additional clearance on the coachbuilders drawings for maximum bump position. WW. now say that they do not want the axle to penetrate further into the frame than shewn on N.Sch.2494/7 and so we must not use the .250" we previously called for. We propose to use 30% stiffer springs instead of the 25% stiffer at present used if we run into trouble at this point as WW. consider this is the best line to take. We shall adhere to the .5" shallower buffer whatever happens. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
