Lots of times people ask how I come up with the projects and mechanisms for the pieces I build. The ideas are generated anywhere, this one while driving along in the car on a recent trip. Back in the studio I imagine the required action, roughly draw the components and action, and then work on a mechanism. After a bit of scribbling a sketch like the one shown here evolves. I make myself notes so that when I get to the detailed prototype design I can remember points of concern, integration with other parts, or things to experiment with.
This sketch is for a future yet to be named piece.
