| LID{A. J. Lidsey} 1237. See me To E.{Mr Elliott - Chief Engineer} from Da.{Bernard Day - Chassis Design} c. Hs.{Lord Ernest Hives - Chair} Da.{Bernard Day - Chassis Design}1/HP.13.9.33. HS{Lord Ernest Hives - Chair} Bensport Universal Joints. These joints still shew a tendency to seize on the pins, presumably the Hardy Spicer shaft is not likely to be available immediately, and something to carry on the present joints will be needed. (1) It is suggested that rear axle oil might be tried. (2) We suspect the hardness of the surfaces. (3) It would be possible to insert a floating bush of bronze by reducing the pin ends to .564". The maximum stress in the pin would not be appreciably altered. (4) Experimental Department have a needle bearing joint already made, adaptable on existing pieces. We can see that there are several ways in which this needle bearing could be arranged. By calculation from information we have these bearings should be well able to take the loads.
