Introduction: NK Sideliner K'nex Ping Pong Ball Machine

Picture of NK Sideliner K'nex Ping Pong Ball Machine

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!

Instructions? This thing is really cool!

Thanks! Sorry I can't post instructions for this because it took a week to build, and I've taken it down already. :/

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

Not bad for a first machine, and I like the name of the lift. :-)

Haha, well it's the first thing that came to mind when I finished it. :P

Thanks man!

hunter999 (author)2014-01-12

Wow, pretty nice for a first attempt, it looks rather neat and nice job on modding the green path element from Paradox!

hunter999 (author)hunter9992014-01-12

by the way, why are there ping pong balls on the track below in pic 3?

nerfrocketeer (author)hunter9992014-01-12

That's a storage area for extra ping pong balls.
