Steering Joggling. In making comparisons of the Goshawk cars between, say 2-Goshawk II and 1 or 3 Goshawk II, the only difference I can find is the increased friction in the steering of 1 and 3, compared with 2. As already reported, we were able to make 2 - G-II the same as the others by replacing the fibre friction washer with bonded Ferodo asbestos. In going into your suggestion of fixing a spring loaded friction device, we do not feel that this can be applied satisfactorily with the present design, but EY. has agreed to instruct for an experimental set of pivots to be made, in which the top bearing bush andthe top part of the pivot pin will be serrated and a friction device fixed, similarly as was fixed on the rear shock absorber. By this means we can increase or diminish the amount of friction according to the plates used, and shall by this means be able to ascertain the right amount of friction required. If you have any further information to convey on this point, please let us know, as we feel that this weakness is one of the salient faults which must have attention prior to delivery. EY. has also instructed for a steering tube to be made up with buffer springs at each end. LOSS of Water from Radiator. Warwick reports that by fixing up both outlets from the bottom of the radiator and connecting to a pipe which fits over the body of the inlet to the water pump, so as to make about 1" bore, the the water is less inclined to over-fill the top tank and so run away from the overflow. He is preparing actual figures of comparative tests made with various devices which have been suggested, and if possible we hope to include this report with this memo. Steering Levers bending. EY. has agreed to instruct a stronger pair of these, which I hope to fix on the next car going to France, 6 Goshawk II. Clutch Springs. The 120 Lbs. spring, i.e. C50468 has now been standardised.
