Counter Parallel Arm Lift, a Knex Ball Machine Lift




Introduction: Counter Parallel Arm Lift, a Knex Ball Machine Lift

About: Hey! I'm Sandroknexmaster. I like building with knex, especially ball machines. I live in Belgium. I speak Dutch, but also English and French. I hope you like my stuff, and like always comment, rate &...

Hey everyone!

Here are the instructions for one of my two new lifts that I've build in my knex ball machine Euphoria. The second new lift is here.
I didn't change anything, except the entrance, I reinforced it a bit.
The lift works good with the newer style balls.
Hopefully everything is clear enough, if not let me know.
If you build this lift, read all image notes please! They will help you a lot!

Have fun building!



Step 1: Piece List

Here's a list with all pieces you'll need to build this lift.
They're named by their original color.


green: 237
white: 45
blue: 144
yellow: 160
red: 165
grey: 20

Total rods: 771


dark-grey: 39
light-grey: 10
orange: 45
red: 72
green: 18
yellow: 233
white: 8
purple: 139
blue: 27

Total connectors: 591


tan clip: 10
blue clip: 2
Y-clip: 33
blue spacer: 69
silver spacer: 106
small blue gear: 4
medium red gear: 2
large yellow gear: 2
medium hub: 1
medium tire: 1
green motor: 1

Total other parts: 231


Step 2: Tower Part 1

We will start with the first part of the tower, that exists out of 2 parts.

Step 3: Tower Part 2

Here's the second part of the tower. Yes I know it's boring to build but just do it, without a strong tower structure the lift won't work!

Step 4: Entrance

The entrance. Here the balls wait to enter the entrance arm.

Step 5: Entrance Arm

Very simple. This small arm will lift the ball from the entrance track to the first arm.

Step 6: First Arm

Here we will make the first of four arms. This one is apart because it's modified, the three other arms are almost the same.

Step 7: Second, Third and Fourth Arm

Now we will build the three other arms. They almost look the same, but they aren't so build everything correctly.

Step 8: Exit

Here the ball exits the last arm.

Step 9: Axle

Here we will build the axle. It's a quite difficult part, sure when you're near the end of this step.

Step 10: Arm Connections

These two parts connect the arms.

Step 11: Crank

Let's build the crank now. You're almost finished!

Step 12: Motor Section

This is the very last step, the motor section. You're almost done!

Step 13: Finished!

Yeah! The lift is finished!

Thanks for building or watching this new lift.
I hope it'll be usefull for your ball machine.

If you've built this lift, please sent me a picture so I can add it to this step.

Till next time!

K'heb hem ook gebouwt voor in mijn volgende bal machine. Het werkte in het begin niet helemaal perfect omdat ik die groene motor niet heb. Maar na enige aanpassingen wel!
