(Requiring Exercises 5, 1, 11, 6, And 2.)

This model for the first time introduces the Brace and Bit. Saw off from Pine a piece 10 in. long, and 3/4 in. square. With the knife, cut one end "across at right angles, and make it smooth. Find the centre of the end as for model No. I. Fix the stem vertically in the Bench Screw, with the smooth end upwards. Fit a 3/16-Shell-Bit into the Brace, and bore a centre hole in the end of the stem as shown in Fig. 2 of drawings No. 6, and to the depth dotted in Fig. 1. Great care must be taken in drilling, so that the hole may be clean and perpendicular. With the knife, pare down each side so as to leave a 1/2-in. square, with the drilled hole in the centre. Find the centre in the opposite end. Mark a line about 2 1/4 in. from the drilled end, as shown in Fig. 1. From that line, shave each side down to the centre last found. Then take off the corners so as to make a tapered octagon. Then take off the corners of the octagon, so as to produce a round tapered rod. Measure from the thick end and mark the exact length, and, at the mark, cut across. Then round the end as shown in Fig. 1, and finish with sand-paper.

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.
