| Contd :- -2- and possibly we may do some good by the horizontal hydraulic damping of the periods when they do occur. In the meantime we are finding out whether moderate modifications will improve the situation. These consist of :- (1) Variations in the vertical pivot, placing it more within the wheel. (2) Lightening the front axle, etc. We have however very little confidence that these will have any affect because the wheels and rims bear such a large proportion of the total weight of the front axle. The stiffness of the springs does slightly help the situation, but as the chief control of the axle is the tyres on the road, anything we can do outside the tyres only seems to amount to 10% in any direction, but if we can find three 10%s, we shall have made a valuable improvement.
