GBC 51 Gravel Works progress continues

The progress is going strong on this one and we have already a few modules up and running. Now is the task of combining them into one big GBC layout.
This next module we want to highlight is lifting a batch of GBC Balls up at once all with a automatic gearbox. Even though we could program a motor to switch between forward and backward drive we think it adds so much more to mechanically accomplish this.
