Fig. 28 — Stag's head in plaster from clay model.
Assuming that the student has managed a cast to his satisfaction, he will see, by looking at the accompanying cut, Fig. 28, that the orbits of the eyes are shallow, that only the upper line of the sinus shows, that the lips and nostrils are also shallow depressions; all of these parts must be hollowed out or undercut. To do this we require a knife such as that figured No. 12 in Chapter III., and three other tools, one a large crooked awl (sharpened at one edge), in handle, and steel "undercutting" and "relieving tools" (see Figs. 29 and 30). [Footnote: Messrs. Lechertier, Barbs, et Cie., of 60, Regent-street, London, have many patterns of these for plaster work, at a low figure.]
Fig. 29 — Steel "undercutting" tool.
Fig. 30 — Steel "relieving" tool.
With these the eyes, nostrils, lips, etc.., of the model, are relieved and undercut, in order to take in the folds of the inner surfaces of the skin of those parts. Be sure to hollow out the mouth upward toward the nostrils, keeping it fine, however, at the lips, and not opening it outward too much; the same with the nostrils, looking to the dead head to note the beautiful curves which can be treated so as to express, at will, rest, alarm, or defiance, according as the under-cutting is managed; the eyes of the model must be hollowed out and deeply undercut to receive the hollow glass globes (see Chapter XII), and the eye pits (lachrymal sinuses) relieved.
Although we have cast the head whilst attached to the body in order to get our difficulties increased, yet we will now imagine the stag's head, with a long piece of neck-skin attached, severed from the body, in the manner in which heads usually arrive from Scotland to be mounted as trophies of the chase. The model being ready, the dead head is now skinned, the skin being taken entirely off the head, and being "double-skinned" as described, washed and cured, is now ready for mounting.
First, however, the horns must be sawn from the skull by cutting away a triangular piece of the bone to which they are attached; drill this bone for two long screws, by means of an American "twist-drill," fitted into an ordinary brace. Next, the prepared model requires blocking; this may be done as shown at Fig. 26. A slot to receive the board should have been previously cut in the plaster under-jaw of the model, or, in a more simple and efficient manner (see Fig. 31), by procuring a piece of "quartering," 3 in. x 2 in., about 2 ft. in length, cutting a channel in the under-jaw and the back of the head to fit it, wedging up, and pouring in wet plaster to make all secure. The head of the model should be cut to receive the horns, leaving about half-an-inch or more of plaster before coming to the wood.
The quartering protruding below the neck must now be fixed in a vice, and the horns screwed in. seats, the screws coming through the plaster and into the wood, which they should "bite" for an inch or so of their length; wet plaster is then poured on the top, and the back of the head made up by the addition of more. When dry the quartering should support the model with horns attached, and all parts should be immovably rigid.
