Contrivance is a modular wooden mechanism machine with a virtually endless amount of configuration possibilities. This mechanical demonstrator is more than just gears; it has nine different mechanisms to mix, match, and move. It’s a do-it-yourself Rube Goldberg machine.
Contrivance began as a “what if.” The idea started several years ago when my friend Chris and I were looking through Henry T. Brown’s book, 507 Mechanical Movements. “What if someone made these just for fun, just to have a bunch of mechanical demonstrators?” we asked each other. “What if they could be designed to all work with a common interface? And, what if they could chain together Rube Goldberg style?” We both thought it would be fun if somebody made this toy-like device for grown-ups someday.
Fast forward to someday. After finishing my Merlot sculpture, I wanted to take a step back from designing larger, complex systems and focus on something smaller, something that didn’t take quite so much time and effort to engineer and build, something a little simpler, and something really fun. Thinking back to my conversation with Chris, I decided to build a DIY mechanism machine. Contrivance is a project that was enlightening to design, fun to build, and a blast to play with. Every time I walk up to it, I make something new.
Plans for Contrivance include detailed patterns and assembly instructions for:
1. Three different size spur gears
2. Elliptical gears
3. Kooky gears
4. Geneva wheel
5. Scotch yoke
8. Hypocycloid Reducer
