| contd:- -3- bush or replace by a bush having an elongated hole so that one brake shoe does not prevent the other from operating. Test this completely equalised brake to see if it is more consistent in behaviour. Further, if you have any of the old floating brakes on the back axle of an earlier 40/50 can you tell us if these are more consistent? Fit up brakes you have designs for and do such experiments as you can until you obtain more drawings. Proceed with fitting up and find the value of the 'servo(. We hope the Goshawk side lever box will leave here this week. You may be able to rig up and test the E.A.C.1 'servo'. You can only experiment with designs and materials in hand as you find profitable. We expect you will not be able to get on very quickly until you receive the modified designs which we hope will meet all the difficulties that have so far shewn themselves. Some of these designs we expect will leave here every few days. We endeavour to shew the present state of the situation as follows :- See original for modifications etc. R.{Sir Henry Royce} | ||
