    That is an intriguing gearset... but I don't see how it could work. When I mentally follow the motions at each interaction point it locks up. Won't move at all. Am I seeing it wrongly?

    Suggestions:
    #1 - Prepare a sketch to explain your setup. Words are inadequate.
    #2 - You describe the motion well, but made no mention of loads, accuracy, or any other requirements.

    The best way to reduce CFM is to reduce bore or stroke. What is the actual force required of those cylinders? Is it possible they are a little oversized now? If you attach them to the frame at a...
