The NK Pongescalator Lift was the key mechanism in my NK Sideliner project. It follows a simple escalator design, with a Mini-K'nex chain pushing up lightweight ping-pong balls to the top. It lifts about one foot, and can use any kind of motor. Only two chain gears are necessary, and they are the only "unusual pieces" in this lift. The entrance track holds the ping-pong ball in place until it is lifted up, and can be attached to any other element. This lift is piece-efficient, sturdy, and fast, and very easy to build, (especially with the above pictures). Anyone who wishes to build this lift and cannot do so with just the pictures I have provided is welcome to ask me (Nerfrocketeer) any questions they have while building. Thank you for looking at the NK Pongescalator lift and please take the opportunity to use it in your next ping-pong ball machine!
