GRYSE me X206 Wor{Arthur Wormald - General Works Manager}2/T8.1.34. HS{Lord Ernest Hives - Chair} BENTLEY - Self Aligning Brake Equaliser Assembly. Referring to the third paragraph of your E/Lid{A. J. Lidsey}2/HP2.1.34 whilst I agree that a complete 10,000 miles test does not seem to be necessary to satisfactorily prove out the modified design of brake equaliser shaft, I do think that very complete tests, both static and running tests, should be made before standardising for production the equaliser shafts in question. I have examined the new shafts with Hy.{Tom Haldenby - Plant Engineer} and we are both of the opinion that it constitutes a major alteration, particularly as one of the bearings brackets has been deleted. It is necessary therefore, that the experimental department should carry out exhaustive static tests from a deflection point of view, and give comparisons with the existing design. I also consider it of great importance that as much actual road running should be obtained as is possible in the shortest time, and that a complete report of the results should be circulated by the experimental department and their full approval obtained. After intensive tests, I should like the necessary results obtained as quickly as possible, as the saving in time and trouble during assembly of the chassis is considerable. When the tests have proceeded far enough, we should again reconsider the question as to whether we should not put in hand counter shafts of the new design, so that production can proceed in parallel with the final tests.
