[DART FOR WHIP-BOW—][Plate 1].
This dart is best made of a shingle. Lacking that, plane a 1/2" board thin[1] at one end to 1/8". Draw the center line lengthwise and lay out the shape of the dart with the broad part at the thin end. Saw crosswise from each edge of the shingle to the place where the curve begins, then lengthwise to that point. Holding the thin end in the vise, pare the curves with a knife, spokeshave, or draw-knife. Make the point at each end with a plane. To plane to slanting lines such as these, it is very important to place the work in the vise at such a slant that the line is parallel with the top of the bench and quite close to the jaws of the vise. Find the point where the dart balances by testing it on the finger, and make the little notch for the string, using a back-saw first, then a knife.
A whip-bow consists of a string 20" long tied to the end of a stick 20" long. A knot is tied at the free end of the string. To throw the dart, catch the string in the notch, hold the wide end of the dart in the left hand and the stick in the right, throw the right hand forward, and let the dart fly from the string.
[1] To hold a board while planing it very thin, fasten it to another flat board with four wooden pegs.
For several of the models in this book, a flat board about 9" × 4" × 7/8" with a cleat nailed to one end and extending 1/8" above its upper surface will be found most convenient for holding thin boards while planing. If the cleat is a little wider than the height of the block on the bench-hook, the bench-hook serves well to hold it.
[BUZZER—][Plate 2].
The buzzer consists of a wheel and two handles, connected with string. To make the wheel draw a 3" circle on a piece of wood 3/16" thick. Draw a line thru the center the way the grain goes and another at right angles to it, thus dividing the circle into quarters, [Fig. 1]. Notice, now, that to avoid splitting the circle, the four quarters must each be cut in a different direction. Lay the model flat on the bench-hook and saw off the corners of the square. Now, holding it in the vise with one quarter up, with the spokeshave, pare the corners in the direction of the arrow in this quarter until the circle is reached. Be careful not to pare away any part of the line. It will be observed that paring can be done safely on the end grain beyond the arrow-head in this quarter, but this is not at all possible on the side grain where the arrow begins. The spokeshave should be held rather lightly so as to allow it to follow the curve. Observing carefully the direction of the arrows, proceed with the other quarters in this same manner. The last few chips should be very fine ones. Drill two small holes for the string 1/4" each side of the center. Sandpaper the model nicely. (See [Sandpaper], [page 11].)
