Hdy.{William Hardy} Rm{William Robotham - Chief Engineer}11/R.26.10.38. B.80 CRANKSHAFT - EB.4104. With reference to HPS{Horace Percy Smith - Experimental Factory Mgr}7/VS.{J. Vickers}25.10.38., we are disappointed that we are unable to make pressed-in oil caps work on this crankshaft. When RHC.{R. H. Coverley - Production Engineer} was in America with me we saw these caps being assembled in Lincoln Zephyr crankshafts, the whole operation being carried out by one man in about 20 secs. We will try and get hold of a Lincoln Zephyr crankshaft, so that you can submit it to your oil pressure tests, because unless we can succeed in saving labour costs by following practices which have proved to be successful in America, we shall always be at a disadvantage from the price aspect. In the meantime, we suggest that different thicknesses of discs and types of grooves should be tried. Rm.{William Robotham - Chief Engineer} | ||
