Note.—This is a repetition to a considerable extent of [Model 1] on a larger scale. The student may be tempted to proceed without going through the processes described, but the temptation should be rigorously resisted, as a satisfactory result cannot be obtained except by adhering to all the details prescribed.

This is mainly intended for an exercise in planing, and it is better to get out a piece of Pine sufficient for two models—that is, about 9 in. long, 13⁄4 in. wide, and 1 in. thick.
Plane one side, and then one edge, perfectly straight and square to each other. Then set the gauge to 11⁄2 in. to fit Fig. 1 of [drawings No. 7]. Apply the gauge to the straightened edge and mark off the width along the smooth side. Then plane that edge down to the line so made, using the try-square to keep the edge at right angles with the straightened side. Next find the centre 3⁄4 in. from the top end, as shown in Fig. 1. From that centre describe with the compasses a semicircle. Then fit a 3⁄16-Shell-bit into the Brace, and bore a hole, at the centre of the semicircle, right through. Then set the gauge to 5⁄16 in. for the thickness, as shown by Fig. 2. Apply the gauge to the straightened side, and mark the line for thickness along each edge. Then plane the rough side down to those lines. Then, with the knife, cut round precisely to the semicircle, using the try-square frequently.
[If a double length is commenced with, as before recommended, the centering, marking, drilling, and rounding must be done at both ends.]
