| HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} [Strikethrough: C. to WOR.{Arthur Wormald - General Works Manager}] [Strikethrough: DY.{F R Danby}] [Strikethrough: E.{Mr Elliott - Chief Engineer}] SECRET. ORIGINAL DA{Bernard Day - Chassis Design}1/M12.2.29. SS.{S. Smith} UNIVERSAL JOINTS. X.7340 With reference to HS{Lord Ernest Hives - Chair}3/LG8229., we notice that the trunnion bearings as indicated on your sketch at the end of the note are definitely more flexible than those indicated on the N. schemes of either the 20HP. or SS.{S. Smith} We do not say the N. schemes are stiff enough but they are certainly stiffer than the standard pieces. We assume that you are not wanting a further design for these pieces.
