Bailey - Chief Engineer} -5- R10/G25/11/21 Contd. of the column could probably more easily be adapted with the suggestion that we already have for brazing on the bottom flange and making a hole in the dashboard sufficiently large for this to pass through. With regard to the steering connections on the axle the best scheme apparently that we can adopt is single split steering connections and set-up springs on the rear end of the side rod as on the first "Goshawk II". With regard to the leather covers on steering joints, I think we should have these laced on as they, in my experience, are superior to those wrapped round and fixed by a strap. (17) PEDALS. I think the front seat is not sufficiently luxurious and that the pedals should be moved nearer the dash. We are investigating this point to see how we can make the "D" type pedals better in this respect. The pedal plates Mr. Hives reports, are rather too weak, and tend to bend over if the pressure be applied at the top, which is rather likely to occur. These will be made slightly thicker. (18) PETROL TAP AND PETROL LEVEL INDICATOR. Mr. Hives suggests that the double level device could be abandoned if we fit a good gauge, and that the tele-gauge shewn at Olympia is the best we have yet seen, and might meet our requirements. I agree to this policy and suggest we obtain some of these instruments and fit them on to the chassis. We should then have a simple stand pipe in the petrol tank fitted with a filter. With regard to the petrol tap, Mr. Hives said there was a suggestion that this ought to be on the outside of the chassis, and between the Autovac tank and the carburettor, so as to be easily got at in case of emergency. We cannot, however arrange this outside simply, and the best and cheapest device we can have is a needle valve on the service tank itself. This device within the bonnet will act as prevention against theft, especially if the bonnet be fitted with locks. There is a "D" pattern of tank design in hand to try to make the rear of the car better and get the spare wheel inside the rear [illegible] tube. (19) BONNET LOCKS. Derby are asking for the bonnet to be fitted with locks to prevent tampering with the engine. This is necessary also in cases of "Goshawk" chassis fitted with magnetos, to prevent theft. (20) ELECTRICAL CIRCUITS ON "GOSHAWK II". v4075 x2338 Owing to the various troubles that may arise through the blowing of fuses, I have come to the conclusion that the following is the best and simplest scheme that we can adopt. Relative to the battery the switch box comes before the fuses, and is protected in case of short within it, by a buzzer contact breaker (like Delco) or thermal breaker (like Remy). Much of the distributing is done in the switches where the wires leave for the distributing fuse and terminal board. There will be separate fuses for. | ||
