| To BY.{R.W. Bailey - Chief Engineer} from Da.{Bernard Day - Chassis Design} c. to CJ. c. to Wor.{Arthur Wormald - General Works Manager} c. to Hs.{Lord Ernest Hives - Chair} X.4263. Dal/M14.3.23. GOSHAWK 11. FRONT AXLE ETC. X.4263. X.4219 We send herewith N.sch.1386 shewing the front axle arranged for radius rods in accordance with Mr. Royce's instructions that future Goshawks are to be fitted with radius rods to perfect the steering. We understand that you wish to order material for a further series of Goshawks in the immediate future, and it would be desirable if this improvement could be incorporated if it is found at all possible. It will be seen that it means a new axle forging which has been modified between the spring and the pivot in order to drop the steering arm lower. A new top steering lever, and a new shock absorber lever are also needed. The object in sending you this is principally that you may get on with these forgings. The remaining details as to the rear end of the rear radius rods etc, we shall send you in a short while. We do not now require the sheath over the front springs, but any existing springs can be used up by inserting a taper bush in the top leaf, where the taper head now fits. We have suggested that both on the side steering tube and on the cross steering tube the position of the lubricator should be altered to directly over the ball which we understand is in accordance with the Expl: Dept's recommendations. We have schemed the radius rods and shock absorber ball ends with a radius where the shank joins the boss. We think that this is an improvement and might be found advantageous on the top steering lever ball end, and we have therefore indicated an experiment that we should like tried, but we do not propose to alter the ball end unless the results are found worth while. It will be noticed that we have somewhat altered the angle of the spring table to suit the new lie of the springs on the chassis. Da.{Bernard Day - Chassis Design} | ||
