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. r2ph 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 further cause of the device operating stickily.
