| Xu4263 To BY.{R.W. Bailey - Chief Engineer} from Da.{Bernard Day - Chassis Design} c. to CJ. c. to Wor.{Arthur Wormald - General Works Manager} c. to Hs.{Lord Ernest Hives - Chair} Da{Bernard Day - Chassis Design}/2M/27.3.23. RE. 20 HP. WITH FRONT AXLE RADIUS RODS. X.4263. X.4261. We send herewith N.scheme 1394 shewing the rear end of the side steering tube arranged on the lines of the flexible joint we are at present using but with the stiffer springs which Mr. Royce wishes used with radius rods. We expect that it will be found that quite stiff springs can be used, and therefore are giving you a choice of two springs, one giving a normal load of 250 lbs., and in case this should be found to be too stiff, another giving a normal load of 175 lbs. We suggest that in any case you might like to try the weaker spring, and see whether there is a definite advantage in a smaller load. The front end of the side steering tube remains as now but the bending is slightly different and we shall send you particulars of this on the general arrangement.
