| -2- With regard to Rdy's. memo., we have not been able to clear this matter up. A test taken with only one steel plate in the clutch drive has given exactly the same result as previously; i.e., the cone bedding hard in the root. From this result we are inclined to believe that the cones, bronze and steel, are not sufficiently rigid. The investigation of this requires following up, as we are on the point of taking up our 15,000 miles test. Hs{Lord Ernest Hives - Chair}/G.W.Hancock. | ||
