| 354 To Mx.{John H Maddocks - Chief Proving Officer} from Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} c. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux}18/AP.8.11.37. 37-EX.PHANTOM III. Tappet Setting Test. Herewith the tabulated results of our test which are self explanatory. We think that arguments could be brought in favour of either cold or hot setting according to the point of view and that actually there is very little to choose between the two methods. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} has found hot setting satisfactory and GWH.{George W. Hancock - Head Chateauroux} has found cold setting satisfactory over a number of years. Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} | ||
