NK Sideliner K'nex Ping Pong Ball Machine

About: Hello! I'm Nerfrocketeer, also known as Nefrock', Nerf, or NK. I am an avid fan of Nerf wars, engineering, and animal activism (but no I don't go overboard). Thank you for A MILLION views (woah!) and making ...

I have wanted to build a K'nex ball machine for a long time, and only recently have obtained the necessary pieces to do so. My first creation of this caliber is a piece of mechanical artwork that I call the NK Sideliner. It uses ping pong balls and a standard green motor, and it has a Pongescelator lift that uses a mini K'nex chain. After ascending to the top of the machine, the balls roll down a green path (a modified version of Sandroknexmaster's Green Path from his ball machine, Paradox) and hits a random-passive selective path separator. They then can go down two paths that are mirror images of each other, first going down a simple green bendy rod path, and then through a chain path decoration. They then roll down the "sidelines" of the machine, and roll back into the entrance path of the lift. Overall it is a simple machine, but I deem it acceptable for a first experience. I will post the Pongescelator Lift in the future, and will continue to makeball machines. A general thank-you goes out the the ball machine builders of the Instructables K'nex community for all of their support and suggestions. O will continue to learn from them in the future! Thank you for viewing the NK Sideliner, it was a very entertaining build!

    Nice! I actually like how you made it portable (in terms of ball machines). Did you get inspiration from the rapid ball juggler?
