The most difficult part is getting a reliable feeding mechanism, especially when the lifting part is narrower... I got this one right quite easily (the low profile blade easily slides below the balls but keeps on stirring so there is no jam): <http://philohome.com/gbc/screw5.jpg <http://philohome.com/gbc/screw5-v.jpg>> ...But I spent hours on this one to get the geometry right. And even now, rarely I have a ball that engages partially in the output drain and locks the rotating liftarm. With the worm gear drive, there is enough torque to overcome the lock but once in a while a ball or two flies across the room...: <http://philohome.com/gbc/pump2.jpg <http://philohome.com/gbc/pump2-v.jpg>> Philo
