Copy to C.BY.Hs.{Lord Ernest Hives - Chair} EP.{G. Eric Platford - Chief Quality Engineer}PN.{Mr Northey} Re the new London Trials chassis, 129-GH, I was very pleased to hear from PN{Mr Northey} that as the result of the work carried out to this car he was entirely satisfied with it when he tried it the other day at Bignall's Corner. The following is an extract from his report on the subject: "You will be interested to know that I have now no complaint of this car having a rough engine when picking up. It is an unusually good example of our standard production in this respect. I understand that this result has been obtained almost entirely due to attention being given to the scuttle isolation scheme, enabling the rigidity of the body to act in such a way as to damp out or prevent the development of vibrations between the chassis and the coachwork. This is achieved chiefly by the use of much denser rubber than was previously employed. "It is, of course, too early to say how far this method may prove effective in all such cases of engine roughness, but it certainly would appear very encouraging from this point of view. It is very important that instructions should be issued at the earliest moment enabling all coachwork to benefit by this method. "I understand that EP.{G. Eric Platford - Chief Quality Engineer} and Hs.{Lord Ernest Hives - Chair} have this matter in hand." Sg.{Arthur F. Sidgreaves - MD} Stamp Text: RECEIVED HFS SEP 1930 | ||
