The long arm that slowly swings down to nearly horizontal, then after the weight transfer swings back to vertical, is inspired. I also like the paddlewheel pump. Video is nice to watch too.
Thanks. That arm was modeled after one I've seen on George Rhoads ball machines. The key is the large aluminum counterweight at the bottom being adjustable so I can dial in the weight perfectly. It is definitely the best new element I've created in a quite a while.
