| To DA.{Bernard Day - Chassis Design} from E.{Mr Elliott - Chief Engineer} -2- El/G19/6/20 Contd. quite easy to put in a single serration, as the metal of the tube would walk up from both directions during the spinning operation, but he thinks that the addition of other grooves will probably require special precautions taken to preserve the form of the first groove that has been spun, and we can hardly hope to get such elaborations carried out at least by Birmingham spinners. He would therefore like you to try a single corrugation of maximum size, that is to say, the size shewn on the drawing, and also a number of shallow corrugations, and further to put it up to the sheet metal people to supply the sleeve exactly as on Lec.1247.
