| Contd; -3- is quite low; and it is certainly surprising, when the water boils, the amount of water which is actually pushed through the over-flow. THBN. is again giving this case serious attention and we propose making experiments on the unit bed for the purpose of ascertaining the rate of flow caused by the pump and the corresponding rate of flow in the radiator and how this is affected under various running conditions. We should be glad to hear from you of the trouble you have experienced in this respect, if any, on your car as we know of no complaint made by you in this respect and we may be unnecessarily concerning ourselves, but from the experience we have had so far, we feel the matter requires some investigation. The action appears to be similar to the 40/50 but much more aggravated. We understood that your trouble is that of the water-over-heating. Do you find this is so even although the radiator cover is removed? In view of your report, however, we have taken up with BY.{R.W. Bailey - Chief Engineer} the question of the largest diameter.of fan as possible being used. We have made a test on 2-Goshawk-ll which as you will remember was a bad one for steering shocks, and as previously mentioned have replaced the original fibre thrust washers with bonded Ferodo without lubrication and we are certainly impressed with the steering of this car as it is very much improved; but at the same time it now appears to suffer from having a little more friction than one desires, although no worse than the limousine car 3-Goshawk-ll which is accepted by the Sales Dept. as being generally satisfactory, and the only reason we can find that 3-Goshawk-ll is free from these road shocks, is because ~~the-steering-gear-on-3-Goshawk-ll~~ of the increased friction and we are proposing to investigate the steering gear on 3-Goshawk-ll to ascertain, if possible, what the actual friction is which is now taking place. Having thus got this information, you may feel keen on trying it yourself on 4-Goshawk-ll. There is no movement at present being made for cut-outs to be used on the Goshawk car. If it is considered that cut-outs are definitely required for Continental cars, we feel that cut-outs should be standardised for all Goshawk chassis. We take it that this action is, however, one which you can most usefully take up with R.{Sir Henry Royce} for definite settlement. As regards front shock absorbers. In order to obtain the increased poundage it will be necessary to obtain different springs and possibly a stronger base. We will, however, take this matter up and see what can be done on shock absorbers on expl: cars at the works. I take it that you think we should be in a position to, at least, turn these shock absorbers out so that when new, they will hold 40 lbs. at the end of the lever. This is in reply to your memo. from Hyeres dated Tuesday EP.{G. Eric Platford - Chief Quality Engineer} R.R. 189 (600) (H) 296. 10s.0d (M) 12.3.17 M.P. 176542. | ||
