Work in Progress: One Ball at a Time

Work in Progress…

One GBC ball at a time :)

We’re currently working on the GBC 62 Lifting Factory (LEGO 8258 Alternate Build), and today’s sneak peek shows one of our favorite mechanisms so far.

The challenge? Reliably picking up exactly one GBC ball at a time before sending it on its journey through the machine. It took plenty of prototyping, tweaking, and fine-tuning, but watching it finally work smoothly is incredibly satisfying.

Can you figure out how the mechanism works just by looking at the photo?

Stay tuned—there’s much more engineering madness to come!
