See C, Topic 81.

New subjects: Relation of dimensions to grain. German bits. Countersink. Screwdriver. Wood: Basswood. Preparatory.

A.   Make working drawing.

B.   Cut one piece 1/4" wider and 2 1/2" longer than required to include all three pieces.

Exercises.

1, 2. Same as in Fig. 1.

3, 4. Same as in Fig. 5.

5. Cut from each end of above piece, one piece 3" long, or 1/2" longer than required for short pieces. 6. Cut one of above pieces to the width of the narrower short piece. Cut out a blemish, if there is one that can be removed in this way.

7.   A. Smooth the largest piece of the three upon both sides, but do not sandpaper. B. Mark with the exact location of the blocks of each end on opposite sides. The distance between the vertical faces of the short pieces should come in the middle of the Length of the large piece, leaving an indefinite distance at each end.

8.   A. Bore and countersink screw holes in small pieces. Make the holes large enough to allow the screws to slip through easily.

B.   Hold the different pieces in their permanent positions by means of hand screws, and drive screws into the large piece to mark the holes there.

C.   Remove pieces.

9.   A. Spread glue thinly on the bottom of one of the small pieces.

Do not use enough glue to squeeze out, or it will make unnecessary work in cleaning it off.

Fig 14

B. Place screws in holes as in Ex. 8, A and B, and turn them in. If the screws do not bring the pieces to a joint, apply hand screws until the glue sets. Be sure that the piece is exactly in its position. Repeat the operation with the other piece.

10. Consider the three pieces as one and treat them as in Exs. 1, 2,

3,4, above, except that the vertical distance between the two short pieces should be the basis of the extreme length. This model should be neither sandpapered nor finished. Enough of these models should be made to keep the shop supplied with bench hooks.
