It has practically been decided to standardise this scheme immediately, the usual standardisation test to be run in parallel, as we feel that any troubles we may encounter through fitment of this mechanism will be preferable to the present complaint of judders, which may lead to a serious accident. In consequence we would like you to proceed with the necessary dies, so that we can produce the parts with the minimum of delay. Already we have had to call for 24 sets. Four dies will be required, 3 for steel forgings and one for an alum. casting. The lever GB.2390 should be made in nickel steel and not alum. bronze for production, therefore we need a die for this. Dies are also needed for GB.2388 and GB.2387. The alum. stiffener GB.2389 will need a die. None of these parts are 'handed'. We think it very important to test these parts on the bumper rig immediately; therefore will you please urge the fitment of parts as instructed in Hs{Lord Ernest Hives - Chair}/AFM.{Anthony F. Martindale}20/JH.4.8.36. A die for the long lever GB.2388 (for use with alum. drums) is not needed at present. Hs{Lord Ernest Hives - Chair}/A.F.Martindale. | ||
