Intro: Falling Arm Lift, a Knex Ball Machine Lift

Hello fellow knexers!

Finally, after a long time, I managed to find some time for this ball machine lift.
The Falling Arm Lift was first seen in my knex ball machine Paradox.
This is the second new lift in a series of 4 new lifts, all from Paradox.
It's a nice lift, with an average piece count for it's height.

However, this lift doesn't always perform very well. The version I used in Paradox worked at 99%, but the second version I made only worked at, let's say, about 70%.
I want to be honest and tell this to you before you start building.
But why making instructions if the lift doesn't work very well?
1) Sometimes it does work, so you can always try.
2) Some knexers requested instructions for this lift, so I'm sure some of you are going to build it.
3) Lifts can always be modified.

If you build this lift, read every image note! It will help you a lot!
If you have any problems or questions, feel free to comment or PM me.

I hope you like it, and thanks for watching / building!

STEP 2: Arm Catcher

This part will "catch" the arm.

STEP 3: Entrance

Here the balls will wait to enter the arm.

STEP 4: Combining Arm Catcher and Entrance + Adding String

First we'll combine the previous steps, after that we'll add the string.

STEP 5: Connection Support

This is the easiest step, it will connect the entrance and arm catcher with the rest of the lift.

STEP 6: Gears

The gears are very necessary to move the arm.

STEP 7: Crank

This is the crank, it will pull the arm to the top and then let it fall down.

STEP 8: Motor Section

This part contains the motor and the rest of the gears.

STEP 9: Tower Support

Time to make some height!

STEP 10: Exit

Here the ball will exit the lift.

STEP 11: The Arm

The arm carries the ball to the top of the lift. This is the very last step!

STEP 12: Finished!

Congratulations, your Falling Arm Lift is finished!
Always slide the switch of the motor to the left!

You can always send me a picture when you've built this lift so I can add it to this step.

Thanks for building / watching!
