K'nex Supernova Ball Machine Instructions

Introduction: K'nex Supernova Ball Machine Instructions

  This ball machine is my first model that uses the white floor to funnel the balls to the lift. The lift is a wheel lift which is a larger than usual one that uses many pieces but still works. This machine has three paths. Enjoy building and as a warning, this instructable is not for the faint of heart. . It only took me a couple days to design this. I just build on the top of my head and this is what came out. Only two balls can occupy this machine at a time because of a long reset period at the end of path one, my favorite element. There are over 4,500 pieces in this model as well. This may take you a little while especially step 2 which may be difficult but it is almost built the same as the original lift.

Step 1: Piece Count Time!

You can skip this if you don't care about a piece count:)

Step 2: Base and Lower Framework

This is where the white floor will be attached to and also holds the yellow return path.

Step 3: The Wheel Lift (Main Support)

This step may make you turn your back towards the project but take breaks if necessary and take your time looking at the pictures. This is the hardest step in the instructable. There are bonus pictures at the end of the step since the second half of the lift isn't that good at different views. 

Step 4: White Floor Ball Return

The second largest step. Take your time. This is a white-connector hog as well! 

Step 5: More Supports

The last step until the paths.

Step 6: Path 1

My favorite path. The last element in the path I got lucky on in terms of it properly working.

Step 7: Path 2

The semi-double path.

Step 8: Path 3

The last short  path featuring a little element I came up with by pure accident, a ball arm that when the ball falls out, it "hops" out landing on a track below. After that, congratulations on making this ball machine and thank you for viewing!

    Thanks, what ever happened to the rating system? Did instructables take it off?
