Rollercoaster Push Lift: a K'nex Ball Machine Lift

Introduction: Rollercoaster Push Lift: a K'nex Ball Machine Lift

About: I like to build with K'nex and Lego.

Here are the instructions for 1 of the 3 lifts that I designed for my ball machine Ribdul.

Click here to see the video, which I am unfortunately unable to post on Instructables.

Supplies

Here is a list of all the pieces you will need to build a Rollercoaster Push Lift:

RODS

  • Micro black: 1
  • Long classic-to-micro: 2
  • Green: 66
  • White: 45
  • White-length flexi: 1
  • Blue: 78
  • Yellow: 42
  • Red: 55
  • Gray: 42
  • Black*: 1

CONNECTORS

  • Micro purple: 1
  • Micro light gray: 1
  • Classic-to-micro: 10
  • Gray: 4
  • Light gray: 1
  • Orange: 14
  • Red: 31
  • Green: 2
  • Purple: 75
  • Yellow: 43
  • Blue: 35
  • White: 27

OTHER

  • Blue clip: 2
  • Blue spacer: 46
  • Chain guard: 11
  • Hinge: 1
  • Long micro rollercoaster track: 4
  • Micro chain link: 132
  • Micro chain sprocket: 4
  • Micro rollercoaster car: 1
  • Micro Y-clip: 12
  • Short micro rollercoaster track: 1
  • Silver spacer: 53
  • Tan clip: 2
  • Y-clip: 6
  • Motor**

TOTAL PARTS: 862 (gray motor) or 891 (green motor)

*This is the same length as a gray rod. You could use a normal gray rod, but it might bend too much.

**You will need either a gray motor or a green motor (your choice), plus some additional parts that depend on which motor you are using.

If you are using a gray motor, you will also need:

CONNECTORS

  • Yellow: 2

OTHER

  • Gray motor: 1
  • Silver spacer: 4
  • Tan clip: 2
  • White gear: 1

If you are using a green motor, you will also need:

RODS

  • Green: 12
  • White: 1
  • Blue: 2
  • Yellow: 2
  • Red: 2

CONNECTORS

  • Purple: 11
  • Blue: 7
  • White: 1

OTHER

  • Green motor: 1

Step 1: Frame, Part 1

You will begin by building the shorter half of the frame.

Step 2: Frame, Part 2

You will now complete the frame.

Step 3: Rollercoaster Track

Now it's time to attach the rollercoaster track and chain.

Step 4: Tunnel

The tunnel keeps the ball on the rollercoaster track so the car can push the ball.

Step 5: Entrance & Exit

All lifts must have some way to get balls onto and off of them.

Step 6: Gray Motor Gearbox

If you want to use a gray motor to power the lift, follow this step to build the gray motor's gearbox.

Step 7: Green Motor Gearbox

If you want to use a green motor to power the lift, follow this step to build the green motor's gearbox.

Step 8: Customize!

The Rollercoaster Push Lift can easily be customized. Here are some ideas:

  • You could make the lift taller or shorter.
  • You could build a full rollercoaster for the car to traverse on its way down the lift.
  • If you want to make the lift taller or build a rollercoaster, you might want to add more cars. Beware, though: every micro rollercoaster car is unique, and each one coasts a different distance up the chain. Thus, you would need to design some way to keep the cars a uniform distance apart.
