(Requiring Exercises 5, 12, 8, 9, 10, 14, 15, 26, 34, 13, 25, And 24.)

This especially involves straight and square planing. Cut from Deal a piece 20 in. long, 6 1/2 in. wide, and 1 in. thick. Plane one side perfectly level and one edge perfectly straight at right angles. Gauge and mark for width at 5 3/4 in. Find and mark the centre line A to B in Fig. 1 of drawings No. 18. Set the compasses to a radius from A to B, and describe, with A for the centre, the semicircle shown at the top of the Fig. Fit a 1-in. Centre-bit to the Brace, and drill a hole with A for the centre, taking care that it goes vertically through at right angles, and that there is no splitting when the bit is nearly through. With the small turning saw, cut round the semicircle at right angles, and, with the chisel, shave off and round the two corners that spring from the semicircle, also at right angles. Then, measuring from the centre of the rounded end at B, mark the entire length at 16 7/8 in., and, with the tenon saw, cut off at the mark at right angles. Then shave and round at right angles the two bottom corners. Plane the bottom edge smooth, and file the edges where necessary. Set the gauge at 3/4 in., mark with it the edge all round for thickness, and plane the rough side down to the mark, perfectly level throughout. Then, with the smoothing plane, take a thin shaving from the first side, merely enough to remove the marks, taking care to maintain an accurate level. Finish throughout with sandpaper.

*** The object of deferring the planing of the second side until so late a period, is that, at the same time, minute chipping and roughness of edge on that side, almost certain to result from the boring and sawing, are at the same time disposed of.
