| P.T. FROM DA. {Bernard Day - Chassis Design} Copy to HS. {Lord Ernest Hives - Chair} BY {R.W. Bailey - Chief Engineer} /HED DA {Bernard Day - Chassis Design} 1/W15.10.31. Y5L10 Y741D ROAD SPRINGS. Referring to BY {R.W. Bailey - Chief Engineer} /G121031, we had the impression that one solid eye was not regarded as a great disadvantage, and had the effect of causing the spring centres to be rather more accurate than when both were rolled. Apart from this however the solid eye fits into the new deep frame more conveniently than does the rolled eye. We should therefore like to have your further comments, namely, some idea as to the increased cost due to using one solid eye. If the matter is very important we would have another go at the spring ends but it is evident that either the negative camber of the rear spring must be increased - which we should be reluctant to do - or the frame depth must be reduced. As regards the front springs we could probably do something by re-setting the frame. As regards the clips we think that if these stand up on the experimental springs we shall have no objection to using them. IA. RECEIVED 16 OCT 1931 | ||
