After all the bellow rebuilding, lubrication, and reassembly; the moment of the first turning motor test arrived. We could not believe it when the motor jumped into action with just a small vacuum from a vacuum cleaner hose held near to the port. Clockwise with one port, counterclockwise with the other. It is great fun to watch the sliding valves sequence the bellows. We decided to skip the timing alignment for the time being – sometimes it’s best to quit while you’re ahead.
How’s are the blue boxes coming along – any progress since the April post – or new pictures?
