did it in 27:35 as well ;-) and no guessing.. but couldn´t see what it was until I´ve finished it.. typical for Da Vinci, it´s often almost impossible to see what he was drawing

It's a treadle. You pump the pedal with your foot, and it turns the wheel to do work for you. Like a sewing machine.

MMM I found that quite tough, It didn't make visual sense until it was almost finished. It was fun t do though - I like a challenge!!!
