| To DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X4613 Hs{Lord Ernest Hives - Chair}/Rml/LG8.3.28. 15-EX CAR IN FRANCE. X4613 X8940B Further to our Hs{Lord Ernest Hives - Chair}/Rml/LG5.3.28. You will see that GWH.{George W. Hancock - Head Chateauroux} reported cracks as indicated in the attached sketch. We appreciate that these are due to our holding the body down on the rubber pads instead of with springs, but the springs allowed too much movement. Possibly we would be able to revert to them if we could use semi-isolation. However we should like to know if you see any prospect of strengthening up the body in the region of the failure. This might also be of assistance in enabling the body to stand up to semi-isolation. We are circulating some information on our experience with total isolation shortly. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} [Text within sketch] Observed cracks. Can we triangulate across A-B to improve matters. | ||
