I haven’t shown you any of my Great Ball Contraption Modules recently, and this is one which I built back in October last year – my Rainbow Cardan Lift. This was the BrickFair 2019 GBC Workshop module by Lawrie George. Plans for his Compact Cardan Lift are available on the Brickfair.com website.
This is another new Great Ball Contraption module for my collection. I call it the Rainbow Rover, and is made to a design by Lawrie George, adapted slightly by me. You can download the instructions for the build from Lawrie’s website.
My next Great Ball Contraption module is the Rainbow Serpentine. The original design was developed by Brian Alano, who had spotted something similar in European GBC loops and made plans of his version available online. This in turn was modified by Lawrie George, who replaced the large cogs in the centre of the curves with the rotating claw pieces to scoop the balls around the lane. I built my module from Lawrie’s plans, once again in rainbow colours with the parts I had to hand. It handles large numbesr of balls in the input hopper with ease, and translates into a steady flow which exits the module at the top behind the spinners.
