    A different engine configuration

    Hi Brian, Great project! The basic design is around 130 years old. Below is a video of an 1891 4 hp Van Duzen inverted walking beam engine along with a new re-design that a fellow in China is working on which is a horizontal version of similar design. Gil

    Verical hit and miss engine

    Why not just add a collar with set screws on top of the green spring? Just leave enough room above it for height adjustments.
