Eric Platford - Chief Quality Engineer} DA{Bernard Day - Chassis Design}5/11.9.22. RE. GOSHAWK 11. STEERING. X4264 [Handwritten annotations below RE line: Y4261 (struck through) X.4265] [Stamp: RECEIVED] It is understood from the discussion yesterday that the first production cars which go out are to be fitted with buffer springs in the side steering tube, having a set-up load which will be determined by the Experimental Dept, but which is about 100 to 150 lbs, and a clearance of .4" at least in one direction. This means that the rear ends of the side steering tubes will have to be changed. The other point is that these cars should have the higher rated front springs, with the front of the chassis raised .5" in order to improve the geometry of the steering. In this case the buffers should be increased .5" so that the range of the spring is the same as now. The following points have yet to be experimented with before it can be decided whether they can go on to production chassis or not:- (1) Increased friction in the pivots, probably by means of a small multi-plate clutch arranged in the pivot. (2) Plain thrust in the steering column. Particulars of (1) will be sent in the course of a day or two, and (2) you already have. The above is intended to apply to the first 50 production chassis which are now going through. If there is anything with which you do not agree, would you please inform us so that we may get a definite programme out for the chassis. DA.{Bernard Day - Chassis Design} | ||
