Put all 3 shaped pieces back into the shell and line everything up the way you want it when it's done. Without disrupting that placement, clamp the thing down on the end where the fork tines and knife and spoon tips are. Then mark on the other end a point that's directly in the center of the width of the piece, and that same measurement from the end of the piece. Draw a circle (if you want) that's the diameter of your dowel. This is where the hinge will go for the whole 'moving parts' idea to work.
