In this connection we would add that in the gear as sent back to you we have fitted a new set of hemispheres which we have given a tempering operation in order to relieve some of the machining stresses. We are of the opinion that this will greatly increase the life of these hemispheres, and we shall be very interested to hear how these new hemispheres stand up.
