These keep the clockworks together The alarm wheel K is the one that works the sort of ratchet that moves the alarm hammer. The wheel M need not be one from a speedometer. It must, however, be one that will. mesh, The drive to propeller N, is a bicycle spoke, with the wheel M soldered to the end of it.
Here is the pattern of the propeller I promised. The heavy lines are the pattern. I have purposely left in the lines showing how I drew the pattern of the propeller. The edges of the propeller are sharpened and the blades bent to the shape shown in the smaller diagram. They are then twisted. The propeller is . attached to the shaft, by soldering the propeller to the nipple of a bicycle spoke. The shaft is a bicycle spoke. This propeller is quite suitable for the clockwork drive as well as the electric motor, though perhaps on a somewhat smaller scale. It depends on the strength of the drive.
