| Hy.{Tom Haldenby - Plant Engineer} from EP.{G. Eric Platford - Chief Quality Engineer} X4086 EP{G. Eric Platford - Chief Quality Engineer}2/LG6.4.22. 5-Goshawk-11. We have received your report dated 4th.inst. I have no doubt, after your run on the 1st. and 2nd. April you will be able to give us some idea of the effectiveness of the undershield etc. on 5-Goshawk-11. As regards the steering levers. It would appear pretty evident from your report that the steering levers have not bent but are in the condition as originally turned out. Although the gen.arrgt. scheme N.999 shows the ball ends vertical the detail scheme for this job gives the lean of the ball to be exactly the same as the lean of the pivot from the vertical, which is 4°. The amount of incline of the ball therefore in position taken over a length of 2" should be about .13 which you report confirms 5-Goshawk-11 as being O.K. in this respect. I have examined 6/7-Goshawk-11 and find that they are as specified above. I have been into this matter very carefully with the Works and BY.{R.W. Bailey - Chief Engineer} and actually discussed the point with the man who built up the three front axles for 5/6/7-Goshawk-11 and I am assured that all these axles were built up with the same list of parts, the same pieces being used in each case. I have carefully examined 6/7-Goshawk-11 in this respect and they seem quite O.K. and fulfil the conditions as above specified, which also seems to be the case according to your report with 5-Goshawk-11. The binding in the neck of the ball end is a point we have also taken up and on examining 6-Goshawk-11 and 7-G-11. they are quite clear in this respect, but there is not very much clearance and I have brought this matter to the attention of BY.{R.W. Bailey - Chief Engineer} so that a little more clearance can be considered. As regards the lean of the ball end and pivot etc. it certainly appears that these are consistent on all of these cars, and in principle, the same as the 40/50. The lean of the ball being exactly the same as the lean of the pivot. I have no doubt that you have now received the two spare levers sent. Is it possible the shape or size may vary to those originally fitted on 5-Goshawk-11. In view of your report, I do not now propose sending the spare set of levers. You do not ask for your last report to be circulated so we are not doing so. I am sending a copy of this report to Hs.{Lord Ernest Hives - Chair} privately, with my reply. Will you please always say on your reports whether you wish them to be circulated or not. In any case, there is nothing in this report of vital importance. EP.{G.
