Introduction: Mutualism - KNEX Ball Machine

Picture of Mutualism - KNEX Ball Machine
This is my 7th KNEX ball machine "Mutualism." This took a little over a month to build with 2 lifts and 5 paths, here are more details.
HERE'S THE VIDEO if you haven't seen this yet:

Step 1: The Bottom & Network

This is where the balls land when they reach the bottom. Then, the balls go up one by one by mathsboy314's Multiple Arm Lift and a Chain Lift.

Step 2: Path 1 (path 4 Connects)

The beginning of this path is the same as the path 5 start out. This path features 95martb's halfpipe element & one of Kairah89's elements from Metropolis.

Step 3: Path 2

This path connects to Path 1.

Step 4: Path 3

This path features Kairah89's spinning basket that doesn't always work for me.

Step 5: Path 5

The two things featured on this path are the panel stairs and panel drop both by 122Heb (Knextreme).

my question is where you were able to get a collection of that many knex

collinjo12 (author)infernisdiem2012-02-20

Well, it's a long story. It all started with the Musical Ferris Wheel. (I really don't want to explain where everything came from, but some.) I got the Red Battery-Powered Motor from the K'NEXosaurus Rex Set. I got all but 2 panels from Craigslist with more pieces. I hope I get more pieces like gold rods, tubing, etc.
