I’m working on a new Essential Mechanism. I will be mashing together the Scotch Yoke from here and a modified version of this six step Geneva Drive from here. The result will be a mechanism where the main vertical shaft moves intermittently up, up, up then down, down, down… Should be an interesting project!

You can see the initial sketches and a stop-motion animation of the Geneva Drive on my Instagram feed and below. Like all the projects on my site, the final design will be available to download for free for all members.
