Shown above is
the assembled top section of the cradle. Drywall screws and
wood glue were used in its construction. Due to inaccurate cutting of
the two tube support brackets, the trunnions are attached to the bottom
edge on both sides of the cradle. The trunnions are made from two strips of 3/4" inch plywood glued together. The bottom piece of which is
shorter at both
ends to fit between the two tube support brackets for the bottom of the
cradle. They will prevent back and forth movement of the assembled top
and bottom cradle sections. A top plate between the tube support
brackets help to provide strength. The top plate can also serve as a
means to attach a camera or other device.
