A simple but yet so effective timings mechanism is featured in our latest GBC 50 Tow Lift – 42128 Alternate Build.
We needed a way to only let GBC Balls go through once the Tow Lift is in the lower and upper position.
We used a combination of levers and counter weights to tilt the ball gate up and down at the exact correct moment. There is even an option to tune the timing once you have finished the build.
One of those cool mechanisms which make us smile every time again :)
