Exchange tips, advices and ideas about this GBC module on PLANET GBC Forum
I have built this gbc. had trouble at first lining up the rotating arms but managed to get it eventually. my only gripe was that you can only use a couple of balls as if there are more than 1 ball at the bottom then it tends to get stuck and will stop working.
Same issue with gears being too tight for me as well. 🙁
Has anyone tried this? I Can’t get it to work. Gears are too tight and don’t spin.
