| Bootts. BENTLEY. X4685. To RNC. from E.{Mr Elliott - Chief Engineer} E.7/HP.13.11.33. ---------------- c. Sgr. Wor.{Arthur Wormald - General Works Manager} Hs.{Lord Ernest Hives - Chair} By.{R.W. Bailey - Chief Engineer} RR. -------------------------- re Metal Floorboards. -------------------- The work done in the Experimental Shopin making mock up sheet metal floorboards has been very helpful in arriving at a decision regarding the final design. Of the three models made we have chosen the one in which the two present front boards are combined to form a single pressing as we think this has many advantages. To make it possible to check the height of the lubricant and top up the gearbox we are moving the dip stick and filling plug to a position under the rearmost board. We consider this is much better than working through holes in the floorboard and we have been able to incorporate them both in the gearbox lid{A. J. Lidsey} so that the modification is applicable to any existing gearbox. This is shown on N.sch. 3670. The filler and dip stick will now be readily accessible by lifting the rear floorboard only. We should like you to make up a set of floorboards to designs LeC's 3690/1, and we hope that when these have been tried out they will form the basis for making the dies. We have not fixed these with a spring fastening at the moment as this type of fastening takes up a lot of room and would prevent us from making the metal boards applicable easily to the existing chassis. We have however arranged a novel form of screw and spring washer which is retained in position by a threaded locking ring which prevents the screw from being lost. Finally, so soon as we have had a satisfactory trial run with this system on the Bentley we shall see what can be done applying the same scheme on the RR. chassis. E.{Mr Elliott - Chief Engineer} | ||
