| X7430 E.{Mr Elliott - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey} c. By.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey}3/KT.17.8.32. P.II. FRICTION IN STEERING COLUMN (Lec.3094) We have carried out preliminary tests on the above scheme as fitted to 20-EX. The scheme is satisfactory when using the stronger of the two alternative springs provided (E.84465). The friction load measured at the periphery of the steering wheel increases approximately 1/2 lb. per half turn of the adjustment. The maximum load obtainable before the spring plates come choc-a-bloc being 4 lbs. It is rather important that provision is made in the scheme to prevent it being tightened up choc-a-boc, at present it is possible to screw up the adjustment so that the friction surfaces are forced up solid and lock the steering. The amount of adjustment necessary to do this is very small. This appears to be the only point in the scheme which requires modification. Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey} | ||
