Introduction: Knex Dual Ball Machine

Picture of Knex Dual Ball Machine
This is my first instructable.  It is a ball machine that has 9 paths, 3 lifts, 5 feet 5 inches tall, and has 3 new elements.  This is my third ball machine, but this is my first on instructables.


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)

Picture of 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.

Instructions for the whole ball machine

Hitchtopher (author)bumboozer2010-09-25

I am not going to make instructions for the whole ball machine. You seem like you have a lot of K'nex. You should build your own ball machine. I will not make instructions for my 7,144 piece thing. Plus I'm not legally allowed to. K'nex owns the rights to it.

What do you mean, "knex owns the rights to it" You created it.

I had no clue what I was talking about then. I just needed an excuse for being lazy.
