Bailey - Chief Engineer} Rm{William Robotham - Chief Engineer}/FJH{Fred J. Hardy - Chief Dev. Engineer}7/R.13.7.38. BENTLEY 60 TIMING GEARS. During our recent measurements of static deflection on Wraith timing gears we have found that the camwheel bends appreciably as a diaphragm. It has been decided to stiffen the B.60 camwheel, EB.3956, by thickening the web, and the modified detail is now being made. Will you please hold up the ordering of the mould for forming the bakelite part of the gear. This is the only part affected. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev.
