A key feature in Da Vinci's illustrations was the application of cage gears, which can also be a practical learning tool for students. Encourage them to examine how this mechanism operates as the driving force. Ensure they understand that the cage gear plays a pivotal role and prompt them to consider why it functions as such. The recommended materials include 5mm plywood and 3/8 dowels, with 3/16" dowels for the cage gear assembly.
