| 224 To G/Rb.{R. Bowen} from Rm{William Robotham - Chief Engineer}/Std. Rm{William Robotham - Chief Engineer}/Std.5/AP.27.11.36. FAN PULLEY CONSTRUCTION We should like you to give us an estimate of the saving in cost (if any) to be obtained by making up our Ph.III. fan pulleys from sheet metal pressings instead of machining them from the solid (see attached sketch.) The cost can be obtained on the assumption that we should use the identical pulley on Ph.III, Bentley and 25/30 HP. Rm{William Robotham - Chief Engineer}/Std. | ||
