sawyer klegr Posted October 22, 2018 Posted October 22, 2018 This lego great ball contraption miniloop uses a ball pump style mechanism to lift the balls up, when they reach the top they fall out of the "lighthouse" down onto the rocks and back to the start again. The mechanism is quite reliable and can be made as tall as you want, if it is built higher it might need extra weights to make up for the weight of the balls though. (I am considering using it for the start of my next module). LDD file. Quote
Carsten Svendsen Posted October 22, 2018 Posted October 22, 2018 I like the style, but the liftarms rotating are really taking the beauty of it away. Consider replacing that with a ball pump Quote
