| K8220 c. to Hs{Lord Ernest Hives - Chair}/Mr Hancock. BY/CSA/DB.{Donald Bastow - Suspensions}5.6.28. Re Phantom - Spring Drive - Sec:5020. LeC.2462/2472. Please receive herewith prints of - E.77646 - Spring (driving). detailed in accordance with Mr Hancock's request for a stronger driving spring. This has been detailed for use with existing parts, and it should be noted that in so doing, the stress has been increased to approximately 90,000 lbs. per sq:in: therefore if this spring is successful, would suggest that design be modified to accomodate a more reason-ably stressed spring. Will you please instruct up one set of these springs. WADE & CROXLEY BY/CS. | ||
