Double Crank Box Prototype

Tue, 17 Jun 2014

As an extension to the Crank Box project I have put together this Double Crank Box. The mechanism is basically the same as the Crank Box project. there is a sliding pad on the top of the box onto which can be attached a variety of different characters, this time though there are two pads for twice the fun!

The crank that drives the pads back and forth are set at one hundred and eighty degrees to each other making them move constantly in opposite directions, perfect, as Mr Cool pointed out, for a walking character.


Here’s the finished project animated. If you squint you can just about make out the pads moving back and forth on the box top.

I have completed photography of this project so I’ll be releasing this and the single crank box shortly.
