We believe that the Order Office are about to order 50 steering cams from the Adamant Co. for the B.V. 50 sets. We recommend that the Adamant Co. should grind the bearing cones before and not after hardening. The cones should then be lapped by R.R. This procedure avoids eccentricity of the cam tracks resulting from inaccurate setting up prior to grinding. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} | ||
