Controllable Pitch Propeller
thingiverse
This is a reverse engineered demo for display at Bay Area Maker Faire. It explains the inner workings of a controllable pitch propeller. Ideally the hub should be transparent but I don't have the equipment. All threads are metric: holes are provided to the right diameter to tap them by hand. Plastic tubing is in English dimensions as that's all that was available locally. The history of the whole project is here: https://www.flickr.com/photos/steamboat_ed/albums/72157643364703844
