Hello everyone! This is an Instructable of a new ball machine lift, the Alternator Lift!

This is a lift I made and worked on for a month. Here's how it works: a tower in the middle of the main tower (called the lifter) has ball grabbers on it. There are ball holders built into the front of the tower. When the lifter goes up and down, the balls are alternated from one side to the other, which is why I named it the Alternator Lift!
This lift does not fit balls from Motorized Madness, Big Air Ball Tower, or Loopin' Lizard.

Fun fact: this Instructable has over 211 pictures.

So, if you want to build it, move on to Step 1!  :-D

I hope you like it!
