Pole Pet Hummingbird Automaton
Your own little wooden flapping hummingbird. Pull the ball to watch him flap his wings and ascend the pole.
He comes in kit form for you to slot together in about an hour, with no glue required. Digital files are also available on my Etsy site if you want to laser cut or scroll saw the parts yourself.
Made with quality laser cut Birch plywood. This mechanism uses two pulleys of different diameter. This means when tension is placed on the string, there will be more torque in one direction causing the spool to wind it's way up the pole as if by magic. Great as an educational toy or an elegant desktop sculpture.
