Bailey - Chief Engineer} X7430 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/LG27.3.28. SEMI-ISOLATION. XW413 We send you a scheme for semi isolation which we have been using with success. We find that it is necessary to use rubber everywhere if we are to avoid squeaks as there is no possibility of lubricating the bolts. We tried spherical washers and rejected them for this reason. We are not at all convinced that the cast dash can easily be made to support the column unless it is arranged as on 12-EX, we think that 14-EX column would move about unpleasantly if the car was driven hard, we know that 15-EX column also with a cast dash was quite hopeless for rigidity. We therefore consider that we should do well to carry on with semi isolation until we have had more experience with the scuttle damper. Certainly, again and again we have cured steering complaints by semi-isolation and so steadying the column. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
