Here is a complete list of lifts that we (people on this forum) have made:

If you're looking for something easy, I would suggest the chain lift. It requires special chain pieces.

If you're looking for something interesting but sturdy, I would suggest a helix lift. It requires special tubing.

Another sturdy lift is the Up and Down Lift. I made a version with a much lower piece-count that I can share with you.

If you're looking for something aesthetic (but big) I would suggest a wheel/ring lift.

If your lift is only raising balls 2ft, I would suggest an arm lift.

Almost every lift requires the ball to start a few inches above the ground, so that the lift can reach underneath the ball.

Here is a simple track to build:

I'm not sure how friendly that guide is for new builders.

You can get inspiration by searching for "Knex ball machine" on Youtube.
If you have any specific designs you would like help with, we can help!

Can you be more specific? What do you need help with?

Is this the video you're talking about? I've made a lift very similar to this and I could make instructions.



It's nice to see new people joining!

I'm at the point where I just number my projects. I can never think of a good name.

I like it, but the squeaking is so annoying.

The ball lands on an arm. The counterweight of the arm contains a gear which can move.
