With regard to the exhaust valve failure, a fitter has been sent to France to replace all the exhaust valves and to fit a new liner and piston. The failure of the exhaust valve was due to the valve being drilled for lightness. We are going to discard the drilled valves. We have this week made tests at Brooklands of the latest type Harrison radiator matrix with a view to having something more efficient for the SpectreCodename for Phantom III if this is required. The steering problem is receiving continuous attention, and we are co-operating with the Marles people. So far we have not made much progress. (2) Petrol Tank. This is being dealt with by the Design. (3) BENTLEY. Isolated Gear Lever. The question of getting this on production quickly is being dealt with by By.{R.W. Bailey - Chief Engineer} Stellited Valves. Textolite Gears. These again are being dealt with by BY.{R.W. Bailey - Chief Engineer} We have been considering the Textolite gears and consider that 50 sets is perhaps an excessive quantity to put through for the first batch. The object of the change is solely to facilitate the production of quiet timing gears. We are by no means certain that production will find these easier to produce than the standard gears. We therefore recommend that the 50 sets should be reduced to 25. | ||
