| 1020 To By/NS.{Norman Scott} from Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} c. Les/AW. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}3/MH.{M. Huckerby}30.6.39. B.V. AND WRAITH III ROCKER BUSHES. Regarding the complaint that the Works cannot broach out the bore of the Vandervell rocker bushes EB.4309 to the final size of .625 dia. without first enlarging the bush bore as supplied by the makers, which when pressed in has a bore of .595 dia., we have taken this up with Vandervells. They consider that .003 -.006 is sufficient to be left in the bore for broaching and have arranged to send along 50 samples with only this amount left in, and after trial and approval by the makers the drawings and any future orders should be made accordingly.
