Use your calipers to find the center of the mannikin on the nose and between the eyes. Align graph and adjust the angle guide to match the mannikin’s width. Set the rear of the glass eye using the angle guide: rule markings, assure an equal distance from the nose. The eye cant is set by free hand aligning the graph to the mannikins. The graph may be bent as needed, but please do not fold. Slit-pupil eyes are set by aligning the center line of the graph with the mannikin. Adjust pupils to the proper angles shown on graphs. Set includes graphs for: bear, lion and canine families, antelope, elk, buffalo, caribou and larger game: whitetail, mule deer, blacktail, bighorn sheep, bobcat, fox and javelina.
