| (sheet 2) at present designed which we should lose by going to the J.III type, and we ought, therefore, to endeavour to secure a good banjo. With regard to the question of slacks in the drive, we had set out before the holiday to design a 3/4 floating end as an alternative to the type issued, which had only the slack arising from the keys to the differential, and which represented a further economy in manufacture. We agree that the scheme put forward by Hs{Lord Ernest Hives - Chair}/Gry{Shadwell Grylls} would eliminate even this slack. This scheme appears to be used on the Ford axle. We understand that this car was found bad for take-up noise, and certainly inferior to the Buick. The elimination of this slack in the axle, therefore, is not a cure for charking as is also evidenced by the Lincoln Zephyr, which uses the same axle. We are rather doubtful, therefore, whether this scheme justifies any big departures in construction. E.{Mr Elliott - Chief Engineer} | ||
