We shall immediately be making a drawing and issuing instructions for the use of rubber buffers being inserted between the scuttle vertical rail and the pot on the dashboard. A modified scuttle isolation print will be issued to all coachbuilders. As soon as possible we shall make RR. scheme of this shewing the rubber in a cup in the side of the dashboard pot mounted in such a way that it may be screwed out after the body is mounted. We shall shortly also shew on the scuttle isolation print the instruction that the rubber supplied by us must NOT be compressed the required amount, and should the scuttle isolation gap be irregular those rubbers in the wider part of the gap must have packing washers underneath them until all the rubbers have the same compression. A further item which affects the regularity of the scuttle isolation gap is the thickness of the edge of the dashboard. When we designed the cast dash it was assumed that this edge would be kept constant by surfacing both the back and front face. If there is no great difficulty we would like this to be done. | ||
