Introduction: Knex Ball Machine Lift: Triple Moving Arm Lift

About: Hey everyone. I'm Thibault Art and my biggest hobby is to build huge machines in K'nex. I like also to draw a lot and take care of my corn snake. On this page you will find K'nex ball machines, K'nex elements,…

Hey everyone,

Here are instructions for the Knex Triple Arm Lift (a knex ball machine lift).

The lift is quite easy to make and rotates very smooth when the instructions are carefully followed. As you can see by the title, the lift makes 3 separate movements when only 1 (6V) motor with 2 dubble A batteries is required.

The lift can also handle multiple knex balls at one time thanks to a little ball dispenser that is connected to the same motor that rotates the lift.

Make sure to check out Step nr 1 to see if you have all the special pieces you need to make this lift, (like Micro Knex pieces, the big green gear, etc...).

If there are any complains, questions or problems about the lift, please tell me in the comments below.

Thanks for watching, building,

Thibault Art.
