  • Hexasphericon toy video

    Some of the long-time members here may remember the hexasphericons I made a while back. They are single surface solids with a continuous flat side winding around them, and look like this:

    They're made by joining to pieces into a blank with pin between them. The blank is machined into a cylinder with conical ends. The length of the cylindrical center section is the same as the slant height of the cones, and the cones are sloped at 60 degrees. After the blank is finished, the two halves are rotated 60 degrees to get the final configuration.

    Well, I finally got a video camera function with my early Christmas present Cannon camera, and I wanted to post a video of the hexasphericon rolling down an slight incline. (Click on the picture below)

        Wow, very cool!

        Did you have a build thread on this?

          I made one too after seeing that thread years ago, I show it to a lot of people and only one was able to guess how it was made.

            The machining steps are here (2 through 18):


            This one had a hollow center, which isn't really necessary and requires a bit more machining. You'll also have to do some calculating to avoid a breakthrough.

            mochinist, seeing that just made my day. Thanks for posting the pics.

              More info:



              Weird shape, hard to visualize until the dimensions along the split line are given.
