Pecking Bird

Notes:

A rather more complicated model to construct. The pecking motion
is obtained by moving the tail backwards and forwards. This is a
good example of connected 2nd and 3rd class levers in operation.

– To ease construction attach all brackets to the base top
before attaching it to the bottom 4½”x2½” Flat Plate.

– Make sure all locknuts are properly constructed.
