Knex Ionization Ball Machine Instructions




A semi-huge project. This ball machine is around five feet tall and has almost 5000 pieces. I designed a wheel gate to make sure only one ball occupies the bottom of the lift. Enjoy building this ball machine as much as I did creating it. This machine also uses the newer larger K'nex balls.

Step 2: Base

A very small step!

Step 3: Return Track, Wheel Lift and Wheel Gate

This is where the new gate system is built and installed.

Step 4:

I managed to make a very long classic spiral lift by reinforcing it with more support. Take your time and build carefully.

Step 5: Other Supports

One last step before the paths.

Step 6: Path 1

Yay! Finally onto the paths!

Step 7: Path 2- Double- Arm

This path uses a new ball arm I invented where the ball uses it twice.

Step 8: Path 3- Torqued-Off Supernova

This path uses a combination of Torque and Supernova elements.

    Yet again, another wonderful ball machine! How do you churn them out so fast? (I'm still stuck on a troublesome element, so my next release will probably be a while.) A well conceived lift system and creative elements. I love the instructions as always; they allow me to catch things I might otherwise miss in the video. Good job, a five star (if ratings were still up) machine!

         I like to follow 1 Thessalonians 5:11 - "Therefore encourage one another and build each other up, just as in fact you are doing." Besides, who likes the people who gripe about the one tiny flaw of a model when there are so many positive aspects to applaud? My specialty is being the voice of constructive criticism, and encouraging people to keep at it and keep improving!
