In addition, it was agreed to analyse the material of the Buick pivot and get out dimensions to see if a further saving could be introduced by making the B.V. in 1% chrome. All parts which mean an alteration in design or material relative to those which have already completed 50,000 miles will be thoroughly tested before being introduced on production. In addition to the foregoing, it is thought that an appreciable saving could be brought about by modifying the needle bearing design, but this will be mainly labour. It will be observed that as a result of this discussion, it is expected that the material cost of the front suspension section could be reduced from £14/15/7 to £11/18/4, or 19%, without having to place orders for greater quantities than at present. We have looked at REC/CAN's cost figures, but have not yet had a copy of them. We should, if possible, like to have detail costs put against the weight analysis which we attach, and of which CAN. has already had a copy for reference. Rm.{William Robotham - Chief Engineer} | ||
