We are, however, still not satisfied with the instrument, and we are continually in correspondence with the manufacturers to obtain further improvements. Item No.14. PROPELLER SHAFT JOINTS. Attention has been paid to the fitting of the leather packing rings by the Works. We are experimenting with an improved method of filling the joints to prevent pressure making the joints leak. Item No.15. STARTER MOTOR DRIVES. We are carrying out work with the Phantom starter motor to overcome the over lubrication and gumminess.
