Knex Ball Machine Radon





Introduction: Knex Ball Machine Radon

Runner Up in the
Community Contest: Toy Rods and Connectors

I built this ball machine back in early spring, but decided not to post it until the K'nex contest opened up. It's a smaller ball machine due to the fact that I still had my K'nex TV stand up. Still, It's got; 1 network, 4 lifts, a motorized ball distributer, and 8 tracks with some awesome new elements that will be posted on my guide.

This instructable is not instructions on how to build the ball machine. I made it that way because it would be easier to show.

If you like my ball machine, please vote for it in the K'nex contest. Enjoy the video! The song is Emergency by Jeremy James Whitaker.

Step 1: Track 1

This is a pretty simple track. Just some tubes and panel levels.

Step 2: Track 2

This track has some cool looking panel stairs and a 2 part ball arm.

Step 3: Track 3

Yay! A roller coaster track that ends in an awesome spiral bowl.

Step 4: Track 4

A new type of panel ferris wheel, a small, horizontal ball arm, and some simple stairs made out of bumpers from the knex pinball table.

Step 5: Track 5

This is my favorite. It's a big reversing spiral tower.

Step 6: Track 6

I call it, The Roller Coaster Stairs Track. A track made almost entirely out of elements made from k'nex roller coaster pieces.

Step 7: Track 7

The fast panel drop. A track witch takes less than 5 seconds to complete.

Step 8: Track 8

And last but not least. Track 8, the longest track of them all.
