| contd :- -2- The 3 short roller bearings might be adopted which should certainly put to rest any doubt of friction in the pendulum lever shaft. I understand we have adopted the longer worm so that the nut does not get partly off the worm on the extreme locks. It will be as well to keep the full area of surface at the ends for the sake of the lubrication and strength. You can use either my idea of forging one lever on the pendulum lever shaft, or Mr. Day's scheme of central flange with 2 levers exactly alike bolted to it, which ever is considered the quicker and better to get going, both seem equally good.
