Gear-Crank Two versions
Two Gear/Crank projects to download and make. This mini-collection has two versions for the gear/crank essential mechanism, one with a long box and a second with a tall box. Turn the crank roughly three times and the crank completes a single rotation. Great for slowing down the action on a project and making the ‘story’ of your automata longer. Members can download the pair of projects for free, thanks for your support. Non-members can join in the fun for £3.50 or equivalent.
Gear and Crank together in perfect harmony. The gear works to reduce the crank speed to just a smidge over a third speed. Use this Essential Mechanism as the starting point for your own character based automata or as an exercise in pure mechanism.
Turn the handle and the mesh gear drives the push rod protruding from the top of the box via a crank. Use this model as an exercise in pure mechanism or as the starting point for making animated paper characters.Â
