Intro: Knex Dual Ball Machine
Step 1: More Information
Hello viewers, this is my Dual Ball Machine. It is my first ball machine on instructables and my third custom ball machine overall. This is also my first instructable. My ball machine has 7,144 pieces. It is 5 feet 5 inches tall, it has 9 paths, 3 lifts, and 3 new elements. It has taken me a bit more than a month on/off to build. I am entering it for the 2011 knexpert search along with two other things. It has taken up about 1/4 of my living room. The other 3/4 are filled up with mess it came with.
Step 2: The Ball Secluder(new Element)
This is my new element, the ball secluder. It is in the picture below. It separates the new size balls and the old size balls. The newer size balls go over the path because they are too big. The older size balls go throgh the trap because they are smaller. In the video on the first page it shows it in action.
