| HS.{Lord Ernest Hives - Chair} ) FROM R.{Sir Henry Royce} DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} ) (At Le CanadelHenry Royce's French residence.) DY.{F R Danby} ) ORIGINAL R2/M19.3.31. X8600 CAR WORK - SPARE WHEEL CARRIERS FOR SIDE OF BONNET. To stiffen the frame when rear foot not used, or with diamond mounting, I quite agree that we must refer to the dash to keep the frame upright. One would expect that if we could control the frame rigidly under the dash that the torsional flexibility between the dash and where the spare wheel is fixed should not be enough to do any harm. DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}'s design for attaching the frame to the dash may be good but one fears this type of flange would deflect. Is it possible to use channel or angle - thus: But I fear it will be necessary to stay straight to dash. Could my angle be continued as a step iron. We can never hope to have rubber mounting for the dash because of the steering, but I do hope that the body and scuttle will be insulated by rubber from the frame and dash.
