I received several request to show the cradle in action while rocking. Readers wanted to see the effect of the 27-inch radius on the action of the rockers. The following 1-minute video illustrates this — click on the link below and the video will appear in a small window, with the background darkened:
It is not a perpetual-motion machine, so someone will have to provide the rocking power. I chuckled while watching and listening to our granddaughters discuss who will be the first to rock their new baby in the cradle.
I am working on resolving a problem with the aspect ratio of the video. Once this is resolved, I will be able to post the actual video directly in this article. Meanwhile, you can view the video by clicking on the link above. Thanks for your patience!
