Copy to -- LHS.{Lord Herbert Scott} C. X4613 X4270 SCUTTLE ISOLATION ON 20.HP. CHASSIS. For two reasons we have been unable to standardise a method of scuttle isolation on the 20.HP. chassis. Firstly we have not been definitely sure exactly how to deal with the problem of 'D' type cars, where the steering column needs support from either the instrument board or dashboard. In the case of 5.G.11. (FHX) the instrument board was tied to the scuttle transversely only, but we now understand that some cars have been successfully treated by fixing the instrument board rigidly to the scuttle, and not attaching it to the instrument board bracket, while the steering column is steadied by using the instrument board bracket on its side only. We have some doubts as to whether such a bracket can give the wheel the necessary horizontal stability and we would like a report from both the Coachbuilding Dept. in London, and the Experimental Dept. in Derby as to the effectiveness of this scheme. Hs.{Lord Ernest Hives - Chair} { The type of scuttle isolation we are inclined to prefer is that using 2 upper bolts with rubber washers. If you can supply us with this information we will then be in a position to get a standardisation sheet for the various modifications put in hand. We will also discuss with R.{Sir Henry Royce} the possibilities of stiffening the 'D' type column in such a way that it needs no further support after the dashboard.
