Double Ring Lift v1.05

Pieces - 450*

The Double Ring Lift uses the newer smaller "banana gears" to provide a rhythmic yet reliable ball lifter. Using a planetary style rotation system, this unique lifter has an intermediate buffer of three balls, and is a very constant and reliable unit.

The Double Arc Lifter uses a slow and gentle arc to clip and transport one ball at a time. Rotational forces are counter balanced by introducing an opposed crank which allows double throughput of the balls. The main input is by a traditional track lifter, which simply feeds up into a rocking intake bin that facilitates singular sorting of balls. This linear ball pattern is regularly “picked” by the action of the sweeping arms and “delivered” to the end chute. The rocking action of the second regulation intake bin is to aid in the reduction of blockages, and to facilitate the balancing of output quantities.

GBC 002_5

Track Lifter

Pieces – 347*

This is a traditional Track Lifter module that has been designed to either be a standalone unit to comply with GBC Rules, or to specifically compliment my GBC Module 002 Double Arc Lifter. The simple curved inner lining of the ball intake facilitates almost no blocks or jams, and eliminates the need for a rotating sweeper or jigger to dislodge concurrent balls.
* May include ball or motor.

This simple looking loop mechanism is a uni-directional single ball lifter. By harnessing constrained rotational force, an elevated arm movement is achieved with a slow and simple cupping method. The ball is lifted along the constraining curve of the “banana gears” and is rolled out of the cupping arm lifter to return to the simple cycle continuously. This mechanism can be hand cranked, and with a flick of the clutch and removal of the handle, a motor can be engaged to provide continuous mesmerising Great Ball Contraption experience.

* May include ball or motor.

Generalised Rules

(pdf document only - No bricks)

If you're thinking about building and designing a GBC module, there are a few things you should keep in mind. First off, you'll want to consider things like dimensions and ball flow so that you can connect multiple GBC modules together and create one big GBC loop.

The great thing about building your own module is that you can make it as simple or complex as you like! Just make sure that your module meets the following 5 rules:

Each module should have an input bin (located on the left side) and an output (located on the right side) that are directly in line with each other.
The input bin should be at least 10x10 studs (outside dimension) with an 8x8 studs opening, and it should be no more than 10 bricks tall.
Your module should be able to accept balls at an average rate of 1 ball per second. You can pass balls individually or in batches of up to 30 GBC Balls.
The output should be no more than 8x8 studs (outside dimension) and at least 11 bricks tall so that it can connect to another input bin.
There are no size limits! What you do in between the input bin and output is totally up to you. Get creative and have fun with it!
