X2654 Our difficulty so far is that of measuring absolutely any improvement we make to the conditions under which the camshaft drive operates. At present we cannot break anything under 20 or 30 hrs. running on the hangar, our most severe test. We have therefore fitted up an artificially weakened drive which we can easily replace. By this we hope to determine the relative value of flywheel effect on the life of the drive, and the benefit likely to be obtained from damping the camshaft or magneto shafts. We also hope to establish a relative value for hangar and bench tests. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
