| 350 M.1770. To Rm{William Robotham - Chief Engineer}/FJH{Fred J. Hardy - Chief Dev. Engineer} from H1/EJW. Laboratory. H1/EJW. 4/JM.{Mr Morley} 30.12.38. FJH{Fred J. Hardy - Chief Dev. Engineer} Phantom III Steering. Your ref. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}3/R.12.12.38. Two inner roller races were submitted from the steering of chassis 3.CM.83. One of these was worn for more than half the circumference of the track. The other race was in good condition. The damaged race was sectioned through the centre of the worn area and diametrically opposite. The depth of case on the unworn section was .024". On sectioning the good race at two diametrically opposite points the depth of case was .032" and .024". Hardness tests on undamaged sections of the races gave satisfactory results. Worn roller race. Unworn roller race. H.{Arthur M. Hanbury - Head Complaints} VPN/30. _______ 752. H.VPN/30 _______ 705. Roller races returned herewith. H1/EJW. | ||
