| 102H. HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} Rm{William Robotham - Chief Engineer}/Les8/R.4.5.37. WRAITH BUMPER CHASSIS. The rear shock damper connecting tubes LeC. 5607 are knocking badly on the above chassis. We should like the following work done in order to reduce the knocking:- (a) The spring load increased as much as possible with existing springs. (b) New springs to be tried having double the load. As at the moment the ball ends and seatings are badly worn, it will be necessary to fit new ball ends F.89106 and seatings F.88010/1. We should also like one of these links built up for W. Bell's damper test rig. Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} | ||
