Introduction: Spiral Stepper 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 & …


Here are the intructions for the fourth new lift in my knex ball machine Elysium.

It is based on the stepper lift, but instead of two sets of steppers, this lift has four.

In step 3, you can choose how high you want to make your spiral stepper lift.

The gearbox is different from the original one used in the ball machine, this one uses less gears.

When you encounter a problem or have a question, you can always send me a message. Thanks for watching / building!

Step 2: Entrance

This is the entrance where the balls wait to enter the lift.

Step 3: Steppers

You can choose how many steppers you want in your lift. I built 13 in this instruction, the same number I originally used in my ball machine. Keep in mind that you have to add three more steppers after this step. That means this lift will have a total of 16 steppers.

Step 4: Exit and First Extra Stepper

This is the exit. There is also one of the extra steppers in this step.

Step 5: Second Extra Stepper

The second extra stepper for this lift.

Step 6: Third Extra Stepper

The third and last extra stepper.

Step 7: Stepper Connections

These parts connect the steppers to the axle.

Step 8: Axle

The axle, where two sets of steppers are connected, twice.

Step 9: Crank

The crank pushes the steppers up and down.

Step 10: Motor

In this last step we will build the motor and attach it to the rest of the lift.

Step 11: Finished!

The Spiral Stepper Lift is finished!

Always slide the switch of the motor to the left.

Thanks for watching / building!
