Bailey - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} ORIGINAL BUMPER TEST ON LATEST PHANTOM STEERING @ .720 LEAD. X8772 X8420 One of the new steerings has been run for 145 hours on the bumping rig. No failure has occurred; all the parts were found to be in excellent condition on examination at the finish of the test. The thread in the nut on this steering is the solid whitemetal type. The proposed standard will be the whitemetal steel thread. There are no signs of failure of the solid white-metal nut which is the same construction as is used on the Hispano. We are continuing the test experimentally using the solid whitemetal thread as it is undoubtedly an easier production job. Hs.{Lord Ernest Hives - Chair} | ||
