| Contd. -2- EH1/LG18.1.19. that the faces which the nuts bolt up against, not being square, this we know is disastrous as regards the bolts breaking. Fitting these frame stiffeners in the frame is a hand job from beginning to end. The stiffener must be fitted to each individual side member as the side members vary anything to ¼". They have to be drilled in position then they have to be taken out and spot faced. What we feel, is that we have well over 1000 wars of this type on the road without the stiffeners and we cannot say that they have shewn any obvious faults which would be improved by the addition of the frame stiffener. Is it then worth while making this change which has not been tested at all on the road or on the bumping rig for the last 500 chassis. Attached to Mr. Royce's copy is drawing shewing the frame stiffener. EH. R.{Sir Henry Royce} R.{Sir Henry Royce} 235A (500 D) (S.D. 408 28-4-17) Bm. 2/158/13. | ||
