Hi, Thank you all for the help, replacing the axle 8 with stop has fixed the issue. Thanks again Steve

Hi, I've been using the slowest speed it now works perfectly except the arm furthest from the motor moves weather there is a ball there or not. Steve

Hi, Not sure what I did because it's now working with balls but only 1 arm worked before, is it sensitive to weather Lego or non-Lego balls are used I wonder. Now to work out which GBC to build next. Thanks again for your help. Steve

Hi, All the cranks rotate it's just that the arms don't lift and I can't see why - even after watching this video. I can gently lift each arm and as the crank rotates I can feel it being pulled down so I know they move freely. Which pieces interact to lift the arms - maybe I've just got something misaligned? Thanks for your help. Steve

Hi, Long time reader but first post having become addicted to GBC. I'm trying to build the lifter triggered by a stuck ball but I've hit a couple of problems: 1) I've built up to page 73 of the instructions but when I connect power only the arm furthest from the motor moves - any ideas what I've done wrong? 2) On page 73 of the instructions in stage 23 it looks like the left black pin goes in a hole that's already occupied or am I looking at it wrong? Thanks in advance for any help. Steve
