[Strikethrough] RE FAILURE OF HIGH SPEED JET CONTROL. [/Strikethrough] Referring to the faulty sample/cap returned from the demonstration class off 89-RG{Mr Rowledge}, it is very evident that the cause of the sticking of the plunger is the fact that an oversize spanner has been used on the hexagon, which has taken the corners off the latter and apparently squeezed the brass housing smaller where the spanner slipped on the corners. It is of the utmost importance that this piece should not be unnecessarily mishandled. With the object of trying to improve the design from a point of view of strength, I propose to carry the hexagon down to the spherical end and form a collar between the main collar on the present upper edge of the hexagon. In the meantime, I do not propose to make this a wholesale changeover job. BY.{R.W. Bailey - Chief Engineer} | ||
