Object

To produce a useful model embodying very elementary processes, viz. sawing, smoothing, shooting, grooving, and nailing. An American clock is utilized for the movement. This must have three small ears or flanges soldered to the sides (see sectional and back view) which provides for the necessary fixing. The bottom curve may be dispensed with if necessary.

The Process

1. Prepare a working drawing of the model upon a 1/4 imperial sheet of cartridge paper, viz. full front elevation and a sectional view.

2. Prepare also a cutting list or timber sheet from the drawing.

3. Saw out and plane up smooth the following material:-

Shoot face edges of all.

4. Shoot face side of each piece on shooting board. Square also one end of each piece.

5. Place sides, back, and bottom together, and mark length across the three edges, also position of grooves (to receive bottom).

6. Mark bottom and top to finished length.

7. Saw and shoot all pieces to length; gauge and plane all pieces to width.

8. Round three edges of top, cut grooves and circular hole for face in front and back.

9. Nail sides on to bottom, then front between sides. Follow by nailing top down.

10. Fix the clock movement, and complete by nailing in the back.
