| To DA.{Bernard Day - Chassis Design} from E.{Mr Elliott - Chief Engineer} -2- E1/G30/6/19 Contd. a sweated joint. The dotted line XX on the pencil sketch Fig.2 on Lec.1105 shews the only places where machining should be performed on the tube extension. This piece should be left unannealed from the pressing operations, as should the other sheet metal pieces used on this job. The nut should be made from a sheet brass pressing bored and threaded. The outside of the nut should be pressed with a hexagon form, or with suitable castellations. The locking of this nut should be accomplished (after the job is assembled in the tank) by sweating. It is thought that for this purpose a blow-pipe can be inserted through the petrol filter hole. The inside of the suspension tubes should be treated with enamel to prevent rusting. Would you kindly proceed with this design in the manner indicated. E.{Mr Elliott - Chief Engineer} | ||
