| To By.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Gry{Shadwell Grylls}: Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}6/KT.1.9.33. SERVO CAMS - 20/25 & BENSPORT. Further to our conversation about the finish of the inclined faces of the servo cams, we suggest that the outer ring G.55341 retaining the balls be made a sliding fit instead of .001 press fit. This ring invariably distorts when pressed into position and is then tight on the moving cam, and is a further cause of the device operating stickily.
