Introduction: Knex Ball Machine Lift: Endless Arm Lift

Picture of Knex Ball Machine Lift: Endless Arm Lift

Hey everyone,

Here are instructions for the final lift that was featured in my knex ball machine ECLIPSE.

If you're looking fore a very reliable lift that you can make as long as you want, this is the lift you need! It works 99,9% of the time when instructions are carefully followed. No rare or special pieces are needed for this lift and it's really easy to build.

I just want to say, if you want to make this lift a lot longer, I recommend you to install a second 12V motor on top of the lift.

The only disadvantage on this lift is the dispenser. The dispenser is only capable of handling 3 knex balls at a time. If there are 4 or more knex balls waiting to be dispensed, it could cause damage to the lift.

If there are any complains, problems or questions, feel free to tell me in the comments below or pm me.

Thanks for watching/ building.

Thibault Art.

Make sure when the arms are perfectly vertical that the dispenser is exactly in this position.

Excellent project. Very pleased with this build.

I made a couple of adjustments as shown in the two images below.

In the entrance, I added the yellow connector. It eliminated the occasional ball jam I was experiencing. I thought about adjusting the ball feeder but this solved the problem for me.

At the exit point, I added a white connector as shown in the second image. The balls were not landing on the exit ramp properly and this bounced them back onto the track.

This is pretty cool! Lift four is the best, because it seem impossible.
