Cow Jump! Download and Make.

Turn the handle on this paper automata and the cow jumps up and down in a completely improbable fashion! 

The model uses a scotch yoke mechanism to drive the cow up and down and a simple linkage to make the legs move.

Members can of course download the parts for free, thanks for signing up! Non-members can download the parts for £2.50
