Camtoys are a popular way of delivering understanding of cams, followers and direction changing mechanisms, but most of all it is FUN. We start by making some basic lever cam card models and progress these to the more complex dog cam toy model ( freely available from me by the way - can be photocopied onto card for students to make ).
If any teacher would like a copy of the basic net for making the mechanism shown here please contact me - Mr. Geekie at the school or simply leave a message and I will post the template to you.
