I'll soon post photos of the double pump I designed based on the
single cylinder one on Mike?'s site. It has a smoother power stroke when the

The small cylinder is used as the bucket actuator in my excavator. Note
the use of a mechanical "amplifier" to get more travel. For photos of
this MOC see...
