Material. - Dressed pine-board, 14" wide and 5/8" thick. Work. - 1. Saw off 17" of the board.

2. Lay out the parts of the box on the board.

3. Saw and plane the pieces to proper size.

The dimensions of the box are: length 8", height 4 1/2", width 5", thickness of material 5/8", depth of inside 3 1/4", as in Fig. 1.

It will take 17" in length of a board 14" wide to furnish enough material. Saw this from the board, resting on horses, after marking with the large pencil and steel square, and allowing for wind-checks, if at the end.

The 17" piece must now be carefully examined on both sides for checks, shakes, knots, sap-wood, resin-pockets, and other imperfections, and the box laid out so that these faults may come in the waste wood. If the wood is clear, the pieces may be laid out as shown in Fig. 2: a, the top; b, bottom; c, c, front and back; d, d, ends; e, e, waste wood to make up for any defects that may occur. Notice that all the pieces are laid out larger than the true size. Thus the top and bottom are 8 1/2" by 5 1/2", the front and back 8 1/2" by 3 1/2", and the ends 5 1/2" by 3 1/2". This is allowed for working margins.

If a 9" board is used, the pieces may be obtained with less waste, as shown in Fig. 3. It would take 22 1/2" length to provide the material.

In sawing out the pieces where they are short, as in this case, those of the same kind should be kept together until after planing; a with b, c with c, and d with d, Fig. 2. The pieces are first squared on one edge, which becomes the face-edge; from this the opposite edge is gauged and planed.

The top and bottom may be put aside without planing until the other pieces are glued together.

Plane to 3 1/4" wide, carefully measure and mark with the knife the length, 8", of the front and back pieces, and saw accurately with the back-saw.

It is sometimes the practice, after sawing the pieces apart, to adjust the cut ends and face-edges together, and make one knife-mark across the edges, thus securing equal lengths.
