Crank!

Thu, 4 Nov 2010

Continuing my ongoing project to mechanify everything into paper, I've been working on a crank based model. I spent longer than usual with the sketchbook just trying to work out how I'm going to lay out this mechanism. I've finally settled on a crank that drives a platform back and forth. First step, the crank.

I've made the crank from a single piece, sort of like the handles that I use for my models but with a few more corners!

With the push rod in place its just a case of folding it up and gluing.

Next, the box. Oh and the push rod will need re-doing because it is too short.

    I was just trying to figure out a triangular folding paper crank shaft along similar principals. Seeing your four-sided version helps me visualize what I was doing wrong.

    Thanks for your site, and all of your hard work.
