| H50b + 1245 W/P. To Sr. from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} c. Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}3/MH.{M. Huckerby}16.3.39. We have a note from IMW.{Ivan M. Waller - Head of Chateauroux} asking whether 10 thou end float in the Wraith first motion shaft bearing is within the allowed limits and likely to cause clonks. The answer to both questions is "yes". Bearings with less end float will shortly be obtainable in the works for use in complaint cases. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
