X1166 E/Ev.{Ivan Evernden - coachwork}5/MN.19.2.36. GRY{Shadwell Grylls} D.W.S. Jacks with Hand Pump. Phantom III Production. We send herewith LeC 5001, sheets 1,2,3 and 4, showing the mounting of the D.W.S. jack pump and the modifications to the piping which we mentioned in our E/Ev.{Ivan Evernden - coachwork}2/MN.14.2.36 as being prepared for issue. We have modified the original design of hand pump and have sent a print to Mr. Sessions to enable him to modify his designs. The remaining schemes show the piping from the pump forward for the front engine foot, and aft to the front end of the rear springs, and also the pipe line from the jack to the pump. The whole of the piping is .250" diameter with .175" diameter bore with the exception of the pipe from the tank to the pump which we suggest should be .312" diameter as drawn. Practically no modifications to the existing pipes and wiring have been made. We have already issued instructions for the remainder of the jack pipes in our E/Ev.{Ivan Evernden - coachwork}2/MN.14.2.36. Ev.{Ivan Evernden - coachwork} Att: LeC 5001. | ||
