This consists of two pieces, as shown in Figs. 1 and 2 of drawings No. 11, each piece so made as to cross and fit the other at the centre, hence called a Flower-Pot Cross, the whole being a test of exactness and good work, surpassing any preceding model.

Cut from Pine a piece 12 in. long, 1 1/4 in. wide, and 1/2 in. thick. Plane one side and one edge at right angles; then gauge for height and thickness, and plane the other side and edge as shown by the section represented in Fig. 3. Saw across the middle so as to make two pieces, and, from the end of each so cut, measure off and saw both to the equal length of 5 1/4 in. each, taking care that both ends of each are accurate right angles. Then place them on their sides and draw the centre line indicated by A B, continuing the line all round each piece. From the centre, mark off the places indicated by e f and g h. At c and d of each, with the compasses, describe the quarter circle shown at each top corner of the figures, striking the segments from the respective dots shown for the purpose near each top corner. Then, with the bottom edge for a base, draw a gauge line on each side of both pieces to the depth represented by ij, and with the tenon saw, make a slit at e and f to the depth of such gauge line. Then, with the knife or chisel, cut out the openings between e and f to the depth of the gauge line, taking care to finish the opening perfectly level and true. Then, at the bottom of one piece and the top of the other, as shown in Figs. 1 and 2, gauge, saw, and cut out the spaces from g to h in the same manner as for the spaces before mentioned. The openings from g to h, if well done, will fit accurately in all directions, and, when put together, will form a firm cross. Then, with the knife, round the corners of each piece, at c and d. Then smooth with file where required, and finish with sand-paper.
